Re: clueless question! - sortof sms/text related

[bruce]

Thanks Mark.

Given me pointers.. Appreciate it.

Ultimately, I envision a backend/blackbox that would handle all the message
stuff, but it seems as though I'm looking for a chat/msg server/client
apps. Ok, narrows down the domain to focus on..

As to the deployment, target group. The focus is the college market, so if
this thing ever happened, and got to 1-2 million, it would be a "wild"
success... but for the testing process, 100-200 test users are more than
enough to really prove the overall concept.

Thanks!

Re: clueless question! - sortof sms/text related

[bruce]

Hi Mark.

Here's my use case.

Master process sends out msgs to 5 people, 'hey, gret deal' 1st 100 people
get it for price X"

The 5 people then send the msgs to their friends, who in turn send to their
friends, etc..


Now, in theory, you can already do this with your cell phone.. You whip out
your contact list, send the msgs.. done!

But for my goal, I'm envisioning a chat/messenger app, allowing the project
to capture/track the msgs, so I guess what is needed is an understanding of
the nuances/issues for a chat/messenger app..

Thanks.

And again, any pointers, either here or offline are great!

clueless question! - sortof sms/text related

[bruce]

Hi guys.

This is totally off topic -- so delete as required!!

I'm investigating a project, and have no clue as to where to start, other
than Google/reseach/etc..

Curious as to how to setup a test system to have test users send/receive
sms/test messages.

If a user has a mobile/app that connects back to the "server" for the msg
handling "stuff" does the process need to involve a twillo/telcom?

I've seen open source projects (zulip) that have the server/client/mobile
parts, but have no clue as to what's involved with architecting or building
out a complete/working solution.

So, I figured I'd ask here if anyone has any insight into this kind of
system, or has pointers to any company/resource that I could talk to.

Thanks guys -- Have a cool weekend!

simple wget question

[bruce]

Hi.

I know.. off topic questions are usually frowned upon!

I was curious as to why the following wget returns a 403/forbidden. The
base url is accessed via the ff/chrome browser.. As far as I can tell/see,
the cmd should match what the network is seeing regarding the
headers/traffic.

Any thoughts.. thanks

oh. ps.

the issue seems to happen with "live" streaming.. i can stream stuff that's
coming from a file server.. ie canned vids/shows/etc.. but something like a
sports event that's happening.. that's choppy

if i reboot, the issue appears to be resolved.

thanks

stuttering/choppy audio/video from chrome/opera

[bruce]

Hey guys.

There's a pusleaudio thread, I didn't want to step on.

I've got a system, and for some reason, I'm getting choppy audio when
running opera/chrome. I've gone into chrome, and I have enabled/disabled
the soundflash plugins.. I see 2 in the chrome:plugins for the chrome
browser.

I'm trying to find a soln short of rebooting. Any pointers would be useful..

I've seen this behaviour from a number other people on diff sites.

And yeah, I know this isn't technically a fed issue!!

Thanks in advance for any pointers you might provide on this.

ok..

so the 0 is local, or remote to you the session/process doing the "ssh"

1) can you do an actual ssh into the remote without port forwarding.. i
know, basic, but it helps..

what you have looks right.. i'll have to check..

 The "unable to resolve host" message indicates you have a broken DNS
 system, apparently. On my system:

 [root@prophead ~]# host raw.githubusercontent.com
 raw.githubusercontent.com is an alias for github.map.fastly.net
 .
 github.map.fastly.net has address 23.235.47.133

 So get your DNS stuff fixed first. Further on, I don't recognize that
 as a standard repo, so you're sorta on your own.

 And as Mark said, the correct adjectival form is "broken".

Hi Mike.

What you suggest sounds like what I might need. Contact me, get me
your contact data, I'll give you a call. I'll gladly pay $$$ to get
this right, And for the right person, this is prob pretty
straightforward, where for me, it might take some time. !!

Re: dns question??

[bruce]

Per mike, and others.

If I understand. I can purchase a domain name "foo.com" I can then use
that name to have sub domains, which can then be applied to the
"boxes" within the internal network. I'm assuming that there's no
additional charge to use the "sub domains" but that these domains can
then be applied to the target instances/boxes of a digitialocean,
mapped to the ip address of the actual instance as defined when the
droplet/vm is created.

So as an example
I could buy foo.com

name   ip address
foo.com   1.2.3.4
nfs.foo.com  1.2.3.5
mysql.foo.com  1.2.3.6
app1.foo.com1.2.3.7

etc... (there would be a bunch more)

with the name/mapping performed via dns of something like a cloudflare..

Is this getting close to being correct?

Thanks guys..

ps. once I get this nailed down, the process will be to auto spin up a
given instance, as well as to perform the dns updates, to create
additional instances to perform the testing for the overall project.

At that point, I'll look into chef/puppet/ansible/shell scripts/etc to
ease the process..

dns question??

[bruce]

Hi.

Researching dns/naming. (sortof fed!!)

Assume I have a server -rackspace/digitalocean/etc.. And I and I want
to serve the DNS via something like cloudflare.

The test server(s) aren't going to be webservers, they're going to be
used to test apps..

As far as I can tell, most of the sites say you need to already have a
"name" from a domain name provider. That can't be right, can it!! One
can have a dns process internal to an org, providing dns names to
machines all over the place. Granted, those machines/names might be
internal/private.

So, does one need an "actual" real name for an externally facing
server in order to process the DNS so one can do a "ssh t...@foo.com"
or can you use something like "ssh t...@foo.example.com"

At the same time.. if you do need a real/actual "domain name" for the
externally facing box, digitalocean provides for both public/private
networks for the linux instances. If you run a private network, would
you then be able to create your own name for the internal instances
that would be available to the other instances on the private
network??

I've tried asking IRC/support forums, etc.. but not getting any progress..

Thanks for helping me get my head around this..

Re: dns question??

[bruce]

Hey Patrick.

Thanks for the reply.

The situation will potentially scale/get to:
-50-100 instances on the rackspace/digitialocean cloud
-the process needs the ability to externally interface with a few of the
  boxes/instances via name as opposed to ipaddress (thus the DNS)
-the internal processes need the ability to be accessible from the other
 instances via name (again, the reason for dns) I'd prefer not to
 do ssh test@1.2.3.4 to instances within the internal boxes/instances
 --names are much easier..
 --the internal machines for the most part are connected to other internal
   instances/boxes..  -- ie, will not be accessed externally

-while one could manage /etc/host files.. not looking to do that for
50/100 instances.. which is why the dns questions are being posed.

Re: selinux??

[bruce]

What the Heck???

So.. people who think/decide to just disable seLinux, instead of
diving in to "learn" it are just lazy  Lord.. shaking my head..

How about.. some might be lazy..

Or, some have a bunch of different things to get accomplished, and
aren't looking to be a sysAdmin, so they want to (if possible) get to
the quickest way of getting their "project" working/tested.. And if
the "security/process" of X (in this case selinux) is in the way.. The
learning required to implement that gets shoved back. It's a
prioritization process for a bunch of people.

You have a limited amount of resources, you priortize and keep going.
And yeah, you realize that you might be cutting corners re security,
but you keep going.

And before people say, "you need to learn security, or you shouldn't
be writing apps!!".. not going to happen.

Implementing "good" secutiry, doesn't happen by spending a few hours
on a few sites. You eventually run into issues that "need to be
solved", etc.. which then adds time/effort/resources. And rightly so,
this is why you have skilled sysAdmin resources. But smaller projects
don't have the resources for this process.. so it becomes a matter of
prioritization/resource allocation..

And I say again.. I've been willing to pay hard $$$ for someone
willing to work with me on security.. No takers..!!!

So, please, no disparaging "laxy" remarks, ok!

Thanks!

Re: selinux??

[bruce]

--Gawd...

Feels like I'm trying to spit in the wind!!

1st, not trying to set up web servers, but am looking at running tests
on linux servers.

2nd, recognize that one should have "secure" systems on the net, but
realize I don't have the time/set of skills to "fully" get there...

So, if you want to say  -- hey, don't have an insecure linux box, it
could be hacked and cause us the Internet community probs due to your
crap, that's fair.

But you need to realize, there are lots of people who are attempting
to do as much as they can with limited resources/time. if anyone here
wants to contact me offline, we can discuss. Heck, I've been looking
for a "sysadmin" type that I can pay, talk with for a bit.

If fed/selinux had a "config" file for simple services/ports, great..
But when you get to policies, and understanding the nuances of
selinux, as far as I can tell, it's a learning curve that has to be
dealt with in order to get it right..

And to be honest, I know of a number of operations/organizations that
have put the "security" sysAdmin stuff off until they could find a
sysadmin resource for that function..

There are lots of "rails/php/nodejs/etc.. " and lots of "be a coder in
4 weeks" courses. that only get to the basics of coding, much less the
sysadmin stuff..

None of these are going away.. so some guy who pops up a website/app
on some aws instance.. has security issues that they might not even
realize..

Anyway.. thanks guys!

Re: selinux??

[bruce]

Look.

I fully get the need for security.. But if I can't get the security
working as it should, but I still need to build whatever the project
might be.. the project is going to get created.

If running Selinux in permissive mode is enough, great, so be it. But
when it comes to policies, for differnt users, applications,
files,etc.. and the possiblity of screwing something up if you go
wrong, then you have a bit of an issue there...  And you can't simpy
tell someone, "if you don't know what you're doing, don't mess with
linux!" Not going to happen..

But hey.. to each his/her own.

My goal wasn't to start a war.. Lord knows there are plenty of those
on the 'net already!

Thanks to all who've replied.

really???

it could also be, prob often is.. is that the person who's doing X is
simply trying to get something done, and not be a Sys Admin!!!

Doing security right.. is an effort in understanding the nuances.. If
you've been playing with OS X, than you might have insight into what's
required. But someone who's not gotten into the "guts" of what
something like SeLinux requires, might not have an understanding of
what needs to be configured, or exactly how to configure it, etc..

Or configuring security (firewall, process restrictions, user
restrictions, port issues, rootkit protections, file restrictions,
etc.. ) might be fairly easy to setup, just not obvious to the casual
user on how to do it.

I haven't met a lot of people in my 30+ years of tech who just gloss
over the impotance of security.. I have met alot who aren't sys
admins.. and, even thought they create software projects from time to
time.. wouldn't have a "clue" as to exactly how to set up a good
secure system.. even thought they'd all say.. would be nice to do it!!

selinux??

[bruce]

Hi.

In testing out creating/setting up remote droplets on digital
ocean/fed (centos), I realize that it should be secured as
much/tightly as possible. However, I also realize that if I screw
something up, I could have an instance that has issues. I'm not a sys
admin, and not trying to be one.

So, here's my question. If I'm going to be spinning up/down an
instance, could I simply disable selinux? For my scenario, I'll be
creating a base instance, with the required apps/processes, and then
using that base instance for any testing droplets I need to create, to
test my apps.

So, if I create an instance, spin it up, fire off my tests on the
instance, run everything for a few hours, and then shut it off, would
that be "reasonably safe/secure"?

My testing apps are a mix of python/php/perl/shell scripts, there's no
web stuff as of yet. Although, there will be dns/nfs/mysql
functionality.

Thanks for thoughts..

Re: screen/remote apps

[bruce]

Thanks Rick,

Thats exactly what I was trying to get to.

The goal, I want to have a local process that iterates through a list
of long running apps.

I want to then spin up a remote instance/screen session on something
like DigitalOcean/DO where I fire up the app, running it on the remote
instance.

The Screen, should then provide a long running process, with the
ability to ssh in, or have a separate app check on the
realtime/ongoing status of the running apps..

As the process grows, I envision having a few hundred of these apps
running/testing...

So, thanks!

Re: screen/remote apps

Hey Markus,

So you're saying it's basically a 2 step process:

1) -ssh remote box start Screen (with starting attributes)
2) --ssh remote box "ScreenCmd --name appToRun"

something like this??

screen/remote apps

[bruce]

Hi.

I can locally run screen, and then run an app.

If I wanted to have a process where I remotely start/run an app on a
remote box (ssh) via screen, How is this accomplished? Can it be done?

Ie, I want the app on the remote instance/box to be running in a
screen process within a term. This would allow someone to login, fire
up the screen process for the screen id, and see the process in
action...

Thanks for any pointers..

Re: digital ocean setup-droplet basic tutorial/questions

Hi Tim. Thanks for the reply.

The goal is to get a basic sys admin understanding of DNS, and how to
apply it to a few instances/VMs.. Over time, the number of machines
will increase. Simply doing the etc/host isn't reasonable.

digital ocean setup-droplet basic tutorial/questions

[bruce]

Hi list.

Taking the plunge to setup some test digital ocean (DO) droplets.
These aren't to be used for web servers, but to be used to run test
apps, and to get a better understanding of actually setting up/plying
with some of the different aspects of a small amount of sys admin.

So, that I don't blow it, I thought I'd post here, and perhaps a few
of my questions can be answered, saving me psin/headache. And hey,
others might learn as well. I've looked over different sites/youtube
vids for a good chunk of these questions, but want to make sure I'm
going down the right path.

I want to setup a few (4-5) different test servers. I want the servers
to be able to communicate with each other via name. I'd also like to
be able to access one of the servers by name, to allow me to ssh into
the box via name, as opposed to ipaddress.

Everything I've seen suggests that I need a domainName, but I suspect
that's due to most people wanting to setup webservers. If I'm setting
up a box within DO's ip range, the box(es) shouldn't need an actual
domain name should they?? I can understand that for a box to be
accessed via/external to DO, it might need a domain name.

  +--   +

box 1
box 2
box3 <<<-- outside boxA (from
internet to box3)
digital ocean ip world

 + - - +

where does the domain name come in?
where does the DNS setup come in.. ?
 box (1-3) will be internal/DO boxes

For each box, I assume I'll have to have a dns entry for each box
(ip/name) yes/no?

Once this gets resolved I can test out setting up nfs/mysql servers,
and having the ability to access the boxes by name from each other.

Thoughts/comments..

Thanks

Re: OT: help with search

[bruce]

Rick!!!

Really, you're throwing this person to java!!!  You're a cruel dude!!!

But yeah, a web crawler is what you need. As stated, do a goog search,
there are plenty out there. You just need an easy to use crawler that
you can point a site at, and the crawler will then iterate through all
the pages on/in the domain, retrieving all the links for you.

Re: OT: help with search

[bruce]

ok...


so you have a 'local' site, not a page, and you want to extract/get
all the links for the 'domain' of the site you're looking at.

you're going to have to have an app/process that crawls the site, and
generates the links.

there are a bunch of open source stuff to allow you to craft a process
to do this, depending on your skillset.  (not sure what your dev
level/skillset is)

you might also have 'plugins' for the browser that will more or less
generate this kind of data.

webscraping/crawling/links  <<< terms if you need them.

let us know what else you need.

Hey Pete/Craig, and anyone else who's replied!!

Thanks for your comments, really appreciate them. There was no reason
to keep the individual replies offlist, just didn't want to have
off-topic subthreads that others might not be interested in on the
list.

However, it might be good to post updates of the process as I go
forth, just to give others the information in case they might want to
chime in, or do something similar.

So, I'll keep you posted. got some more reading to do!

Thanks all!!

Re: anyone here play with rackspace/disgitocean/etc...

[bruce]

Hey Jack.

Thanks for the reply. (aptos) as in santa cruz aptos??

How are you at answering dns/security questions? I'm thinking of
testing some of the tutorials for using cloudflare/dns to allow a
couple of test droplets to be accessed/viewed using the dns of
cloudflare.

The security, well given that my goal is not to be a sysadmin, I know
that screwing up the basic security is somewhat dangerous.

Thanks

hey...

is your issue, you have a specific site you can point to, and you want
to get links off the site?

or is it something else?

digital ocean - setting up secure dev system.

[bruce]

Hey guys.

Thinking of taking the step and putting Fed on a test digital ocean droplet.

Has anyone done this that I  can talk  to/work with to save time/steps.

Basicaally, looking to have a test setup with 3-4 droplets
-minimal ports/services
-mysql on one droplet
-nfs server on one
-dev boxes for the other 2

want to be able to have whatever secuirty is required to lock down the boxes
-want to have php/py on the dev boxes
-is yum/dnf used?
-want dns, to allow me to connect from boxA to boxB by name instead of
ip -- can this be done via cloudflare?

-might also tie git/new relic/etc to have monitoring/backup in place as well

what will I need? I've been looking at different articles and see
different approaches, so figured I'd post here. (sure I'm not the only
one!)

I want to get this all right/correct, as I want to do a writeup, and
walk some others through the process..

So, you sys admins who've been so helpful, pointers, articles I should
definitely hit! All are appreciated.

Thanks

off topic..

[bruce]

Hey

-I know this is off topic of pure fed/rh/centos.

I'm thinking of stepping into playing/testing the learning curve of
the cloud systems. Basically, setting up a test network of a few
boxes, and going through the entire processes of having a working
'cloud' system, using a few cheap instances from Digital
Ocean/Atlantic.net/etc. Not sure I want to tackle AWS.

So, I thought I'd post here to see if anyone has gone through this
kind of process that I can have email/irc conversations with. I'm not
trying to be a sysadmin, so I'm not trying to get really involved.
I've even got some $$$ to throw at the right resource if you're
interested,

I've created a basic list of items that I think would make sense to
know how to do as a start.

If someone is interested, or even if someone is interested to want to
gain this kind of knowledge/skill(s) as well. Hit me up.

Thanks guys/gals!

starting to look at the cloud...

[bruce]

Hey guys/list.

I know. This has nothing to do with fed/centos, but it might be
helpful/useful to others.

I'm starting to lean to tinkering with a couple of instances in the
cloud - DigitalOcean/Atlantic.net/rackspace/etc...  (Not sure I want
to play with AWS as of yet!)

My goal, to get a bit of exposure to how to do basic
dns/provisioning/monitoring of multiple instances. To be able to craft
(quickly) whatever has to be created to be able to spin up/down, have
a couple of separate apps running on different instances, and having
them interact with a test db, that kind of thing..

In order to get the above, gotta climb the learning curve. Keep in
mind, I'm not looking to dive into sysadmin stuff any more than I need
to!!!

So, any pointers on where to turn to for initial docs/stuff to look over..

Heck, if I could find the right resource, I'd pay to get where I need to be!

Thanks guys..

set the tmp file for sed??

[bruce]

Hey.

I know. This is probably really basic/subtle, but 'net searches are
coming up empty.

Doing testing of 'sed' it's generating tmp files in the base
directory. Is there a way that the 'sed' tmp dir can be set to '/tmp'.

A sample sed cmd would be

sed -i '/foo/cat/g' abc.dat
sed -i '/foo/d' abc.dat

thanks..

sed question??

[bruce]

Evening..

As a test, the following is an attempt to replace text from a test
file with text from an external file.

aa=$(cat www1.txt)
sed -i s*#\tISSUES/NOTES::*$aa*g foo.py1

When I check the foo.py1 file, I get $aa in the file, instead of the
replacement text.

The test is using replacement delimeters for the sed, as the
replacement text has slashes...

thanks for any pointers.

curl issue?

[bruce]

Hi Group.

I've got a curl issue that I figured I'd post here as well, given that
this is a slow posting day for fed! Normally, I wouldn't post non fed
things here, but this is a slow day... (I've also posted this to the
curl list as well..)

Heck, I'd even send your fav bev if you were close by!!

Got a short test that should work. The test is doing a
curl/fetch of a page from a site that's running jscript on the back.

The test has stepped through the initial pages/using
Firefox/LiveHttpheaders to see what the network traffic is actually
doing. This is replicated in the test curl functions. The app uses
cookies/SSL, but no user/password login process..

It's actually pretty straightforward as far as I can see.

However, the test is not able to generate the target page, and in fact
seems to be running into a 302 somewhere.

The goal is is to generate the page after the initial pages that has
the list of the dept alphnumeric selection list.

If someone can point out what I've screwed up, much obliged.

Re: wget issue

[bruce]

aha.. we have success...

steps to repeat:

generate the base page to get the initial content, as well as the cookie

wget -S https://isiscc.smc.edu/pls/apex/f?p=123:1:12101780574999:;
 -O  smc.dat

extract the required cookie:
ORA_WWV_APP_123=ORA_WWV-HtXgmY8ZHOxc5O9zc8N8j6tP
ORA_WWV-HtXgmY8ZHOxc5O9zc8N8j6tP

this goes in the wget as the cookie header

use the returned smc.dat file to determine the required attributes
that change.  In this case, we need


p_instance=257747591540
p_page_submission_id=4686527047365
p_page_checksum=DB5BF68CB0895706468BB180F90F4C3B

search/copy these vals from the data

in order to generate the post data, you can do it in a couple of ways.
I viewed the returned post data from a few different pages of the site
in my fav viewer/debugger, and determined that all of the variables
appear to be the same/consistent.  For real accuracy, and in a
crawler, it would be useful to simply do a xpath on the hidden
name/vals  and use that data to generate the post-data.

but we cheat for now:
so the base post-data consists of
p_flow_id=123p_flow_step_id=1p_request=SUBMITp_arg_names=6371933991931405031p_t01=Spring+2015p_arg_names=6362920808091113318p_t02=1+%2C+2+%2C+3+%2C+4+%2C+5+%2C+6+%2C+7+%2C+12p_arg_names=6362811294857854001p_t03=%27OPEN%27+%2C+%27CLOSED%27p_arg_names=6374897696943587288p_t04=20151p_arg_names=3851224476948135099p_t05=1p_arg_names=3851225084220137224p_t06=2p_arg_names=6361666501512343398p_arg_names=6362829299321902607p_arg_names=6363404907668258054p_arg_names=6363528795332614067p_arg_names=6363575091232717019p_arg_names=6363649096707888902p_arg_names=3851458085236906098p_t13=April+02%2C+2015+%40+12%3A05+pmp_arg_names=6372068906550664708p_t14=cls_web_list_20151p_arg_names=6372277789412047762p_t15=web_cat_sched_20151p_arg_names=6361721707633487104p_t16=where+cat_grp_seq_num+in+%28cat_grp_seq_num%29+and+cls_status+in+%28%27OPEN%27+%2C+%27CLOSED%27%29+and+print_seq+in+%28print_seq%29+and+print_seq+in+%281+%2C+2+%2C+3+%2C+4+%2C+5+%2C+6+%2C+7+%2C+12%29+and+nvl%28gnr_emply_name%2C%27*%27%29+in+%28nvl%28gnr_emply_name%2C%27*%27%29%29+and+nvl%28ssn_days%2C%27*%27%29+in+%28nvl%28ssn_days%2C%27*%27%29%29+and+sct_begin_week+in+%28sct_begin_week%29+and+nvl%28begin_time%2C%270%27%29+in+%28nvl%28begin_time%2C%270%27%29%29p_md5_checksum=p_instance=257747591540p_page_submission_id=4686527047365p_page_checksum=DB5BF68CB0895706468BB180F90F4C3Bp_v07=80

wget issue

[bruce]

Hey guys. I know this isn't a fed/linux issue, but thought I might get
some pointers. This has also been posted to the wget list as well.

Trying to fetch class content from a site.

Tested the site, using firefox/firebug appears the site does a couple of calls.

Created a quick shell script to implement the test calls, but for some
reason, cant seem to generate the actual class list.

Steps:
-fire off the initial page
-select the 1st dept accounting - use/leave the rest of the defaults
-implement the select btn, to generate the backend calls.
-in the testing of the 2nd step, the test uses the actual post-data as
generated via the firefox/firebug test

The results of the 2nd call - returns the same data as the initial
call to the base page. I assume Im missing something simple, or else
the app is doing some jscript on the backend that I'm not seeing.

using -vvv for verbosity doesn't point to anything as far as I can tell.

Thoughts/pointers are welcome.

thanks

Re: Wireless can't ping wireless

[bruce]

Hey Jim.

I'm going to cheat!! But given that you're retired, you might have a
bit of time. Is there a big box (staples/bestbuy/radioshack/etc...)
close by. If there is, go get a cheap/different router
(wired/wireless) and test to see if this box gives you the same
behaviour.

To be honest, never run into this kind of issue, but given murphy, I
know that sometime in my future I will!

Let us know.

thanks

 Sort of doing the same as well

 FWIW, the router itself has a diagnostic screen and one option is to
 ping an IP address.  So, wonder if the OP has tried pinging a wireless
 system directly from the router.

 Also, another tool to try would be tcping.


   Now why did I not think to try pinging from the router itself? It's a
 good damn thing I am retired. Anyway, that is an excellent idea and was
 going to try it. However, now, for some reason, both Fedora 21 boxes can
 be shutdown, or their wireless interface disabled, and when brought back
 up can be pinged without a problem from my wired computer. Bizarre. I'll
 keep watching this. When it happens again I'll try pinging from the
 router.

   The original problem is still there. I cannot ping from wireless to
 wireless. I have three Fedoras and one Ubuntu systems, all wireless. No
 box can ping another one while wireless. They can all access the
 Internet just fine. They can all ping to a wired box. The wired box can
 ping/ssh into them (I currently have 4 ssh sessions open, 1 for each
 laptop). If I change to the wired interface it works as expected. Yes, I
 am using the correct IP (gee even I can do that correctly). I'm back to
 being convinced this is a router issue. It's too bad the jerks at
 LinkSys wanted me to pay them to attempt to get it resolved.

   I'll look into tcping and/or tcpdump soon.

open source - drawing/online app

[bruce]

Hey guys.

I know, this has nothing to do directly with Fed. However, I'm looking
for a good/free online app that can be used to do network diagrams.

I was really into draw.io, until it appears that I can't copy a item
from one document to another within the browser. IE, if I create a
block in tab1 in the browser, and do a select/copy I can't then do a
paste of the copied item to the new tab/doc.

draw.io is good, as you can create as many/complex diagrams as you
want, and save them to the cloud/local. If I could solve this minor
issue.. I'd be good to go!

If anyone has a good/free online soln, feel free to let me know!! (Or,
if you know how to solve the issue I mentioned. Couldn't find anything
via searching, that worked for me. -- btw, I tried
Firefox/Safari/Chrome with no luck)

Thanks

 It has similar performance, Atheros hardware and perfect dd-wrt/openwrt

 regards Jens


  Calling that a nightmare is a real understatement. How did things get so
 stupid? Anyway, I believe there are two separate problems here. The
 router is almost certainly part of the problem, and Fedora 21 has a
 problem that Fedora 20 doesn't. I will investigate this more thoroughly
 and report back.

  Thanks everyone for the help.

what do you want to the cluster to do?
how much management do you want to do?
do you want to slap VM/virtual machines on each box?

more data from you might get more useful comments!

 In the old west: first come land rights.

 or stepping on someone else's channels..


 As I wrote over a decade ago, the SSID is there to share the channel.  Much
 like NETBIOS SCOPE back in the days of large, bridged ethernets (which we
 are seeing again in places like stadium wifi! Bounjour makes a mess of those
 environments).  A polite SSID tells who you are so that those around you can
 know where to go to coordinate channel usage.  With 11b/g you only
 effectively have 3 channels, and with planning you can avoid conflicts.
 With a little overlap you can even work 4 channels.

 11a/n and 11ac have more channels, but shorter range.  Speed or range; you
 choose.

 wifi permits numerous packets on same channels,, yes of course there
 might be interference.. but you gets what you pay for!


 Have you ever tried to set up wifi on a trade floor?  A real mess. You have
 to get everyone to turn their power settings down so that their signal stays
 near their booths and not try to cover the whole show floor.  Of course
 BEACONS range much further than you can actually use the network.  This is
 why warflying works.  And why you want power values as well as channel.

 And why NOT use the channels to get better performance?  Be aware and work
 with those around you and everyone gets better performance.

 I just found a little tool, WiFi Radar, that is at least reporting the
 channel, which is what I need right now.  I would like one that also shows
 signal strength.

 I installed kismet, but it does not seem to be working

wifi - repeatedly disconnect/reconnect

[bruce]

Hi guys.

Dealing with a centos 6.5 that's going to be moved to fedora, but I'm
trying to resolve an issue before it gets moved.

The box is running centos 6.5, completely updated. The box is running
NetworkManager, and connecting to a wpa2 wireless network. The wifi is
usb rt5370 ralink. The box has updated elrepo driver

# yum install kmod-rt5370sta

Tried to use different usb/wifi devices that are still rt5370 based,
no change. Tried to switch different usb ports, no luck. Also tried to
connect a different box with the same results.

Rebooting, gives the following that gets repeated over time..

 Perhaps, if you want to try it out, try out one of the LiveCDs first with

 Just a suggestion.

 Hi guys.

 Dealing with a centos 6.5 that's going to be moved to fedora, but I'm
 trying to resolve an issue before it gets moved.

 The box is running centos 6.5, completely updated. The box is running
 NetworkManager, and connecting to a wpa2 wireless network. The wifi is
 usb rt5370 ralink. The box has updated elrepo driver

 # yum install kmod-rt5370sta

 Tried to use different usb/wifi devices that are still rt5370 based,
 no change. Tried to switch different usb ports, no luck. Also tried to
 connect a different box with the same results.

 Rebooting, gives the following that gets repeated over time..

process tbl

[bruce]

Hey..

A test app does a fork, creates children processes.

Is there a way to view the procTBL ps to be able to see that a
process is a child process?

I know you can see when a child has stopped, but the parent is still
running.. but is there a way to see if there are running children,
some attribute that denotes i'm a child?

Or, is there some attribute that denotes the process has running children?

thanks

thanks !  I discovered that the ps -ppid parentID would return the

 Every process has a parent process id (PPID), allowing you to deduce the
 parent-child relationships.

 The GNU ps f option will display the process tree with parent-child
 relationships.

[bruce]

Hi.

Got a network of fed/centos boxes.. The boxes are a combination of
eth, and wifi, with ra3070 chipset.

We reverse tunnel into a couple of the boxes that are wifi, as well as eth.
The boxes have dhcp.
We're using a dyndns kind of service so we can access boxes via name
instead of straight ip address.

Running into an issue where it appears that a couple of the boxes hang.

I can ssh into a box.. and when i try to enter a cmd.. the ssh/term shell hangs.

If I (sometimes) can access the same box from a different window/term
then it appears that the box/term is back to being active..

At the same time, I can sometimes ping a box by name, and I get a no
route for the name.. and if I then use the straight ip address, it
still doesn't return..

This then seems to resolve itself after a few mins...

Any thoughts on what I can start to look at to resolve what the heck
is going on!!

I have no access to the dhcp server, or the wifi router.

thanks guys!!

centos6.5 and I think fed 19.. the issue appears to be on the centos for now..

increasing inode count

hi.

got a test drive, single partition

i'm trying to figureout how to increase the inode count

the drive is formatted, single root partition, fixed inode count

trying to figure out how to increase the inode count

i can do that/increase the inode if i have a partition, and i
unmount,reformat/ use -T news to increase the inode ratio, etc..

but I can't figure out how to accomplish this on a single drive/root partition

Re: increasing inode count

[bruce]

and how does booting off a separate device allow you to change the
root partition /dev/sda inode count?


you still have to then format the dev/sda drive, partition it, place
the os on it, but you're back in the same place!

unless there's a way to use the os install gui, to somehow increase
the inode count at this step.. and there might be if you do a post on
the kickstart, but I haven't found any step by step process on how to
accomplish this..

Re: increasing inode count

[bruce]

Thanks Paul and others.

I've had some tell me that you can do the inode increase as you create
the drive/format it/partition it if you have a post % % process.. but
no one has been able to tell me step by step how to do this!!!

If I use the gui to do an install.. can't figure it out..

A workaround (ugly at best) is to create the initial root partition on
a small chunk of the drive, and then go in and reformat/repartition
the rest of the drive, and then increase the inode ratio.. which is
kind of cheating!!

But doing it in one step/process.. cant figure it out!



Thanks!!

 Typically needing more inodes means that you are using the drive to
 store many small files.  Typically this has to be planned into your
 file systems when you create them.  The ext3/ext4 file system IIRC
 doesn't let you change number of inodes once the file system has been
 laid down.  A file system like XFS might be more useful for your case
 storing many small files since it manages inodes in a different way.

hey cameron...

ok.. that gets me a drive - formatted / with partition, so when the
install process asks if i want to install or reformat.. is there an
option to allow me to simply install on the already
formatted/partitioned drive?? even though it won't have a previous os
on it??

I'm going from mem, I don't have the install docs/site in front of me.

thanks

 Just create the filesystem by hand using mkfs: mkfs.ext3 or mkfs.xfs etc as
 appropriate. See man mkfs.ext3 (et al) for the requisite options. Then:

   mkfs.ext3 ...options... partition-device-name

solution for a quick/robust/secure broadcast issue

[bruce]

Hi.

For a test network, internal 192.168..x subnet, I've got some boxes
that are connected to a dhcp server that I have no control of.

I'm looking to test/play with some services on the different boxes,
but would like to have other boxes be able to reference the boxes
running the services. My issue, the box running service X could have
ip1 which could then change to ip2 the next day..

I'm considering some sort of cheap/fast broadcast process where the
machines running the given services, broadcast out to the network i'm
boxA running service Foo on ipXX and the listening machine would then
decouple the message, and update the resolve.conf file, or whatever
the required file is to then be able to use the required name/ip for
the service..

Thoughts/comments??

Would nc be good for this, would there be a better solution?

Should I create a limited user on each box, and have a process
attached to the user listen, and process the messages?

Thanks guys..

Hey patrick.

couldn't really find any good pointers on this.

any step by steps you can point me to.

ie, boxA with ipA is running mysql and has name boxA

the dhcp of boxA might change day to day

user on boxB wants to be able to get ip of boxA

how can avahi be used in this case?

thanks

 Isn't that pretty much what Avahi does? Why reinvent the wheel?

Re: solution for a quick/robust/secure broadcast issue

[bruce]

so essentially,

the process would have each system in the sub net, report it's
address/name to the external dyndns service, where it would be
managed/returned as a subname, which would then populate the
local/internal resolv.conf (or whatever is required) to allow the
local services/users of the subnet the ability to access the boxes by
the subnames...

could work..

 Wouldn't that just return the public facing address of the network,
 rather than the individual client addresses?


 No.

 You would request sign-up for the service and use their internal domain of 
 dnsdynamic.com and request a subdomain of that.  Then you'd give you systems 
 hostname.mysub.dnsdynamic.com.  Then you'd configure ddclient to send you 
 system's IP address to dnsdynamic.com when it changes.

 Typically, you'd then send it your internal, non-routeable IP address such as 
 192.168.0.12.  You'd do this for all of your systems and then have them 
 address the other systems by these assigned names.

usb/wifi -

[bruce]

hey...

i'm testing on a couple of fed/centos boxes, using cheap ralkink 5370
chipset usb/wifi adapters

i'm getting the following msgs in the /var/log/messages which
indicates that i've got a major wifi issue!!

i'm looking for input/thoughts on trying to debug this to see how to
correct my data issues!

basically:
-how to see/determine exactly how much throughput (download) i'm getting
-what can be done to throttle if this is needed..

the boxes are on a shared wifi router, could this be causing an
issue with other boxes attached to the router as well??

thanks

Re: usb/wifi -

poma...

uber cheap! i'll post the data if/when I can find it. might have
tossed it all ready!!

lsusb - all I have for now..
Bus 001 Device 002: ID 148f:5370 Ralink Technology, Corp. RT5370
Wireless Adapter

As far as I can tell, the device isn't being swamped at least not from
looking at wavemon..

But yet, I had the data in the log file...

And there might have been something else going on that I just haven't
come across yet..

thanks..

Re: SOLVED - Re: Renumbering partitions on an external drive

Hi Robert..

So out of curiosity... what were the exact sequence of commands you used!

 does it.  'w' does not work in expert mode, nor does it give a warning if
 you do 'fiw' so the changes never got written.  You need the 'r' to first
 return to the main menu.  'm' for help really helped!

tracking down crash/error in app running on fed/centos

[bruce]

Hi guys.

running an app in both fed/centos test machines and getting a seg fault.

I know this is a bit off topic, but it does related to segfault
crashes, and how to get/setup the data to analyze track down the
offending code!

to begin,
the system has /var/log/messages with
Sep 30 11:40:57 dell2 kernel: courseSectionDa[3270]: segfault at 868
ip 7f80e8e1e410 sp 7fffe404d0c8 error 4 in
libgearman.so.8.0.0[7f80e8e18000+26000]

isn't this saying the crash is coming from the libgearman.so.8.0.0 as
opposed to the parent php app which uses the gearman lib??

and assuming that this is the case, and i installed the gearman so
with yum (without source) is there a way I can setup the system to
capture the crash data to do an analysis of the crash??

the parent app runs multiple (1000s) of times, and somewhere the crash occurs..

thanks guys..

fed/centos question

[bruce]

Hi.

Really a reinstall question.

You can have an install server for http/ftp/etc install
You can also have pxe startup, as well as the base install from the dvd/network.

However, I'm trying to figure out how to go about (if it's possible)
to do a reinstall of a system remotely.

I'd like to be able to ssh into a box, and then do a reinstall of a
given system  based on the different kickstarter file that I created.
I'd like to ssh into the box, run a given cmd, use a given kickstart
process and have the entire process just work!

But I've been looking all over to try to figure out exactly how this
would work or what all the issues are.

Any thoughts/pointers would be helpful

The target boxes would be centos6.5 (and above) as well as fed 18 and above..


Thanks guys..

testing of drives!

[bruce]

Morning --

Got a situation where we have a number of used/older dell boxes
running centos/fedora (should be the same process of testing the
drives).

Some of the boxes have already had the OS installed/drive
formatted/patitioned/etc.. Some have dual drives.

We realized that we should have tested each drive prior to
installing/formatting/etc..

So, now we're wondering what's the best/god way to test the drives.

We'd like to put together a basic process to allow us to test the
given drive, preferably with the drive in the box/running/formatted so
we don't have to test the drive in a separate box!!

So, any input we can get on software to use, articles to review, etc
in order to get a stable test process to get a good idea of the health
of our drives would be cool

Issues to consider::
-We have running drives, that are partitioned/formatted
-we have drives in systems that we haven't started to use
   some primary formatted/some are installed as 2nd drives

we need a way to be able to test all of the drives, preferably
 without taking the drive(s) out of a box and testing them in a separate box

Concern is/are:
 -bad sectors/blocks
 -health of drive
 -capacity of drive
 -etc..

we've looked into hdparam/smartctl

thanks guys!

update::

The boxes can be remotely/ssh accessed, so it would be easier if
there's a solution that could allow us to simply run software tests
over the net, to the boxes/drives that are installed/formatted if
possible!!

thanks again!!

 Why not set up a compose key? Then you can make all kinds of symbols,
 foreign language characters, fractions, whatever. ™ is just one of the 
 symbols
 you can make easily. (Compose, then t then m.)  Look up Gtk Compose Table

printer configuration all commandline!!

Hi.

Looking to figure out what I've missed/left out in setting up printer
access to a network/wireless HP printer. I can access the printer from

But I can't figure out/recall what has to be used from the command line!!!

so, if i have a test file cat.txt, I thought the command to print was
 lpr -P HP-Officejet-Pro-8600 cat.txt


but that appears to just place the file in the queue..
now, i can get the file to pring if i open the file in the gedit app,
and do a print!!

so, what the heck am i forgetting!!

I cleared the queue
lprm a number of times, verified the queue is empty via lpstat..

resubmitted a test file, same results.

file is listed in the queue, but seems to be in a wait state.. and
again, using gedit, I can print the file.

curious eh?

 active  ihubuse 10  child.php   1024 bytes
 1st ihubuse 12  (stdin) 4096 bytes


 so, if i have a test file cat.txt, I thought the command to print was
  lpr -P HP-Officejet-Pro-8600 cat.txt


 but that appears to just place the file in the queue..
 now, i can get the file to pring if i open the file in the gedit app,
 and do a print!!

 so, what the heck am i forgetting!!

 thanks


 Your lpr command prints a file on my system.  Try clearing the cups
 queue first.

centos/fedora install without gui!

[bruce]

Hi guys/list.

Looking into installing centos/fedora and I'd like to increase the
inodes on the partitions. So I'm trying to find a step by step process
to accomplish this.

As far as I can tell, the GUI/Anaconda doesn't have any place for me
to insert the increased inode count.

Comments would be appreciated.

ps.

I know I can take a partition offline, reformat it, and increase the
nodes, but I don't see how one can do this with the primary/root
portion of the drive on the same system..

thanks

ok...

but given that I've asked for how to be able to install centos/fedora
so I can increase the inode count!

still trying to figure this part out!  ie, where/how does one do the
cmdline/level install and where would the attribute for increasing the
inode count occur..

thanks

 The installer will not provide any interface where you specify the number of
 inodes.
 IMHO, it is for the good or the overwhelming majority of users, who do not
 understand
 the consequences of specifying their own inode count.

 The short of the long is: Fewer inodes are normally used for filesystems
 that
 will contain very large or huge files and hardly any small files. Thus most
 of the
 disk space is used for file storage.
 The converse is that a considerably larger number of inodes would be used
 for filesystems that will contain mostly small files, thus allow a larger
 number of such small files.
 But with the increasing size of disks, this issue becomes less and less
 of a concern for most users.

--mke2fs pre-computes the ratio of number of inodes to total number of
available block in the chosen partition

are you implying/saying that there can only be a single inode count
for a given patition size??

in my case, I'm going to have a large number of small files (2-5K) and
I might have millions in my test.

 6. Now make sure you are root (su) for running the command mke2fs.

Re: centos/fedora install without gui!

[bruce]

per a number of different articles, one of which:
http://www.thegeekstuff.com/2013/01/mke2fs-examples/

# mkfs -t ext3 -v -N 70 /dev/sda6

appears to allow you to simply raise the number of inodes for the
given partition that's already been create

in actuality, it appears that you can achieve an increase in inodes by
either increasing the inode count, or by increasing the ratio...

I have no idea of the risks of either approach.

And I have no idea if you can increase the inode count for a partition
without increasing the size of the partition as well..

seg fault - how to track down cause!

Hey guys..

Running a test parent php app that's a long running app. It spins out
test child apps via the system call periodically. On an intermittent
basis, the parent php app dies, and I get a segmentation fault error.

Any thoughts/pointers on what I can setup from an OS perspective to
allow me to track down exactly what's causing this to happen..

Re: Affordable 802.11n USB dongle that IS supported in Fedora

umm..

if i plug in a usb wifi.. and NM comes up, and I can access a network
via the dongle.. then yeah, I'd argue that you can determine if the
dongle is supported by linux fedora by plugging it in!

 So is there a USB 11n dongle that IS supported and can be had for  $20?
 Actually an external antenna is a plus as it will be on a server that at

 You cannot determine if a usb wifi dongle is supported by linux by
 just plugging it in, nor by brand name.
 You have to know the chipset inside it.

 For example, see
 http://wireless.kernel.org/en/users/Drivers
 and since you are looking specifically for USB dongles, see

abrt questions??

[bruce]

Hi.

Doing some tests on fed/centos boxes..
Running a test app, that in turn kicks off a bunch of python apps..
The test is long running. for hours!

However, somewhere along the way, the py apps die/crash. In looking
over the /var/log/messages logs, I see the abrt indicating it's
captured data for the crash, but it seems to also then delete the data
it collected.

An example of what I'm seeing is below.

I'm trying to figure out what parameters I can set, and where I need
to set the attributes, to be able to capture/analyse the resulting
data to figure out why the test py app is crashing..

Thoughts/comments would be useful..

Thanks

 It saw a crash from a python script that is not part of any package in
 Fedora. So, there's no where to report it to. :)

 You would need to consult with whoever wrote/setup:
 /home/ihubuser/crawltest_denny/rprofParse.py
 on your machine.

bash/shell script question??

[bruce]

Hi.

Trying to run multiple copies of a test as a background process.

I can easily cut/copy/paste the test cmd in the shell, and a check of
the procTBL shows the instances are all running.

However, if I do the same thing, and put it in a test shell script,
when I run it, I don't get any of the instances running...

I'm flumoxed!

any thoughts on what I've screwed up/forgotten.

are there system err logs I might check to see what the issue might be??

thanks

i know run:

from the cmdline, and the test doesn't run in the background.. it runs
as a current/foreground process...

thoughts??

 are there system err logs I might check to see what the issue might be??

 thanks

background - stopped how to kill!

[bruce]

Hi.

I know this isn't really a fed issue, but I'm curious to how to handle it.

I have a basic test php app foo.php

I run it from the cmdline - it sleeps, it dies, life is good. The pID
is removed from the procTBL as expected.

However, if I change the running to be -- foo.php  so the test runs
as a background process, the process gets listed as Stopped T in
the status of the procTBL.

My question, is how the heck can I implement something within the test
foo.php to have it die/be removed from the procTBL when it dies..

I've implemented the kill_posix within the app, and I've searched alla
over trying to resolve this..

So, what the heck am I missing.

And I know I could have an external app kill it, but that's the same
as killing the foo.php test from the cmdline..

Thoughts/comments..

thanks

Re: background - stopped how to kill!

[bruce]

Hi Russell,

the test code is::
#!/usr/bin/php
?php
/*

parent.php

/ycrawl/dcrawl/run/yolo-master/parent.php

test to see about the  background process
*/

print start \n;
sleep(5);

print stop \n;

$t=posix_getpid();
//system(kill -9 .$t);
posix_kill($t, 9);
exit();

?


As you can see, there's nothing special about this. And yeah, when
runs as foo.phpit shows up in the procTBL as T in the status.

There are no filedescriptors in the test.

 If it's stopped that means it's not running, it's probably got an fd to the 
 tty open
 and is listening for input.  Not designed to run in the background.

 kill %1 might work to kill it.

ok...


here's a basic solution for the issue I faced with the dell/broadcom
wireless card/nic.

unning
lspci -nn | grep AR8162
lspci -nn | grep RTL8188EE

or
lspci -n grep '01:00.0'

unning

or
lspci -n grep '03:00.0'

however, for the broadcom, it appears need to build from src..


yum groupinstall 'Development Tools'
yum install redhat-lsb   this didn't result in any file being downloaded
yum install kernel-devel-$(uname -r)

yum reinstall gcc --downloadonly --downloaddir=/dell

yum groupinstall 'Development Tools' --downloadonly --downloaddir=/dell

for the groupinstall.. had to do a bunch of yum reinstall steps
create tmp dir, with all the rpm files..

$mkdir -p ~/rpmbuild/{BUILD,RPMS,SPECS,SOURCES,SRPMS}
$echo -e %_topdir $(echo $HOME)/rpmbuild\n%dist .el$(lsb_release -s

(Note: The rpmbuild option --target=`uname -m` is only required for
EL5 32-bit builds.)

#
# ok - for the above build step, you need to make sure you copy the
# tar file from the broadcom site for the 32/64 bit system
#
# the build process uses the complete tar file, so it doesn't have to be
# extracted
#

once you build the process, you get an actual rpm in the RPMS dir of
the rpmbuild tree that you can use/install, to actually have the
kmod-wl driver for the broadcom nic.

 # modprobe -r b43 b43legacy ssb wl lib80211
 # modprobe -r bcma (Note: needed for EL 6.4 and later)
 # modprobe lib80211_crypt_tkip
 # modprobe wl




eth0 issue::
ok - to get the p5p1 to be seen as the eth0
did a  system-config-network-tui from the term/cmdline
selected the p5p1 and changed the name to eth0, added the rest of the
 required fields
saved the data
-this seemed to generate the /etc/udev/rules.d/70-persistent-net.rules file
-did a reboot and the system now shows via ifconfig -a eth0 instead
 of p5p1 as the eth device...

 4) Download the Broadcom driver matching your architecture (i.e.,

 The tar.gz file for the driver is listed on the page, but I'm not sure
 if I'm supposed to place the entire tar.gz file in the SOURCES dir

 Or, if I'm supposed to follow the readme listed on the broadcom page,
 and build the wl.ko.

 Once I get this resolved, the rest should work ok...

ssh/dhclient

[bruce]

Got a test iisue/problem.

The situation is a group of test servers in a network that's managed
by an upstream DHCP server.

I have no control of the upstream DHCP allocation of IP addresses.

All the test servers (5) are running centos 6.5 as a test. (I know,
this is a fed channel, but the issues shoudl be the same!!)

The test boxes, run the nic/eth0.
The boxes run NetworkManager
All the boxes have the same /etc/resolv.conf
All the boxes can ping each other

All the boxes are on a subnet of 192.168.5.x

The issue I'm trying to track down, is that one box can't seem to
access the external 'net, ie ping www.google.com doesn't return, and
an actual test of ping 1.2.3.4 where the 1.2.3.4 is the actual ip of
google.com doesn't get processed.

I'm running/testing all of this remotely, so I was trying to see if
there's a way to change/force a new ipaddress for the box in question.
I'm curious to see if changing the ip on the box, will result in the
test ping working...

Thoughts/comments things to check??

Thanks

 As I understand it, there's a process/way to use dhclient-scripts to
 generate hook functions that can be called, which can then dynamically
 update the dns using nsupdate...

 Doing that with the client sound rather odd.

 My LAN has a DHCP server that configures the clients, and updates the
 DNS server (on the same PC as the DHCP server) with all the addresses of
 the local machines.

 I suppose it's possible to have your DHCP client do a similar thing.

Re: dns/dhcp client - hooks??

[bruce]

tim..

i have complete control over the local dns

the local client machines are given hostnames upon creation/boot up..

the idea is to be able to have someone within the local network,
who'[s machine has been configured to point to the local dns, to be
able to use the boxname foo to get to the machine instead of the
ipaddress of the foo box.

normally,, all of this would be handled by thre dhcp server.. in this
case it isn't.

so you need to do a kludge which involves updating the local dns
server/records with the updated mapped ip/name.

 And you have access to a DNS server that you can reprogram??

 If so, then have a look at the already existing coding for the DHCP
 servers, and apply the same with your client.

Re: dns/dhcp client - hooks??

[bruce]

kevin.

the whole/partial reason for all of this.

the local system with the dhcp, doesn't have a dns!!!

you come in the lab, connect, you get your ip. as to the external
world, the dhcp serves the dns for the rest of the world. as to the
internal boxes, you get an ip, nothing more!!

it wasn't the intent to have boxes hooked up for long... we're bending
the system... so to do that, we'd rather not have to always recall
ipaddresses,  so we're going to kludge this..

 And you have access to a DNS server that you can reprogram??

 If so, then have a look at the already existing coding for the DHCP
 servers, and apply the same with your client.

 can you 'dig @primaryDNS your.domain.com axfr' the primary DNS server?  If 
 you  can't you probably won't be able to do what you are
 hoping to achieve as the primary name server isn't allowing you to do a zone 
 transfer.  You would essentially have to know each and
 every host and do a name lookup of each and every host one at a time and 
 capture that information and build your zone(s) that way.

 Kevin

 better yet, why don't you just point the dns clients to the primary dns 
 server, set the domain to search, and do the name resolution
 that way?

Re: dns/dhcp client - hooks??

[bruce]

tom..

which is what i'm doing! or rather attempting to do

tom, sorry for the frustration, but this is exactly what I asked in
the very 1st post on this.

I asked, how one can go about updating a local dns using nsupdate from
the clients, based on the dhclient updates, or words to that effect..

 the local system with the dhcp, doesn't have a dns!!!

 It could. You could run your own DNS server in the lab
 for the lab systems and have it forward DNS requests
 to whatever server the lab systems currently use. That
 way the lab systems see each other's names, and they
 all see the outside world as well.

Re: dns/dhcp client - hooks??

[bruce]

and tom

what you state/propose only works if the dhcp server/process is
configured to accept the propogated returned name from the dhclient..

if the dhcp server is not configured to accept this.. you need to
update the  dns (local dns) in another manner.. and this is my case.!!

i know.. a pain...

 I know nuthin about nsupdate. I've used dhcp and bind together
 to provide dynamic DNS, but I did it a long time ago and I remember
 it being very much not fun to get it all working. The dhcp
 and the dns server have to be configured to talk to one another
 and they need keys installed on both systems to verify they
 are supposed to be able to talk, etc.

 Then the dhcp client on each system needs to know to tell dhcp
 it's name (which seems to be something that needs configuring
 differently on every linux distro - sometimes it is automatic,
 sometimes you have to poke config files with a stick :-).

 My named.conf file has something like this in the global
 options:

 options {
...
forwarders { other DNS server IPs; };
 };

 Then has a:

 key DHCP_UPDATER {
   algorithm hmac-md5;
   secret some generated key gibberish goes here;
 };

 Then I have zone file decls to setup a local subnet.

 Then the dhcpd.conf file also has the same DHCP_UPDATER
 key section and zone definitions that mention it and
 correspond to the zones in the named.conf file.

 It also has this option:

 ddns-update-style interim;

 There is probably more junk that needs to be done
 because I remember taking weeks to get it all to
 work :-).

ssh - reverse tunnels

[bruce]

hey guys/gals.

Got an issue where I'm getting hang ups for ssh, where I ssh into a
vm, and then using a reverse tunnel to hop to another box..

here's the basic process:

box1 - create (via cron) ssh/reverse ssh for the vm
-sets up the box1 sshd, as well as the reverse ssh tunnel
  going from the vm1-box1

ssh into vm1 from a box - box is outside the ip sub domain of the box1/vm1

on the vm1 box- ssh into the box1

successfully get into box1/ip1

wait a bit.. few mins, etc..

box1/ip1 times out, user can't type in the term window for the box1/ip1.

go in the vm1 - find the ssh/ps ID for the reverse tunnel/ssh
 netstat -Nplv | grep ssh
kill it, wait a bit for the box1 machine to reset as it realizes
the tunnel is down..

you can then redo the ssh...

but it will still timeout!!

i've changed the ssh_config on the vm1
i've changed the sshd_config on the box1 box

---

however, I'm getting timeouts on the box1. I can wait a few mins. and
then the term for the box1 hangs.

I can kill the ssh/reverse process on the vm, and the box1 will
eventually reset, where I can then get into the box1 again..

I'm trying to figure out what config parameters should be set in the
ssh_config/sshd_config for both the vm1 and box1 processes...

I'd like to be able to access the box1 and not do any action, and have
the term be active (no hangs) 20 mins later!!


thanks

Re: Root Frustrations

[bruce]

Hey Mike,

You could always/perjaps use VNC, and remotely access the vnc app over
a secure ss tunnel, or just access VNC via it's regular/assigned vnc
port.

VNC works, gives you a complete desktop to run whatever you'd run on
the normal desktop. And yeah, the downside is it's slower!

 Good question.  Basically a couple of specialized applications that I run

 I would guess that there might be someway to start a Gnome session from

 Thus if  I can't login to a Gnome session I will have to stay with my old

 Any ideas?

 What would be wrong with the usual method? Meaning, log in as an

 I also remote login to my servers all the time, but I've never ever

example kickstart (ks.cfg)

[bruce]

Hi.

Looking to see how to craft a kickstart (ks.cfg) file by hand that
demonstrates the overall process of setting up a hidden partition, as
well as regular partitions on the drive.

I'm looking to play with creating a regular install of centos (or
whatever) on the main partitions, as well as do some test pre/post
commands..

At the same time, I'd like to create a hidden partition that I can
then do some pre/post functions to play with how the hidden partition
gets created.

The end goal, would be a test process that would allow me to
install/boot into either side.

As to the hidden partition, I'm assuming that this implies me creating
a partition that's not viewable from the df -h commands... Or am I
missing something here. Or, maybe a better question, is there a way to
create a partition that I can boot into that can't be seen by the
casual user using the usual system/disk cmds?
(Looking over different sites/ariticels via the net, not sure about this 
part!)

So, any pointers to sample cfg files would be helpful!

thanks

Re: example kickstart (ks.cfg)

[bruce]

Hey pete!

basically, starting to see exactly what a dual boot process is, how it
works, how the cfg file is setup, etc..

and as I understand the drive, once can create different partitions,
which can then be split to have multiple boot processes.

I was looking into how to actually have a process where the
masterside, can have an app, that can be run, which then invokes a
process on the hidden partition/boot process to then reinstall an OS
onto the master side..

so I'm really asking two questions:
1) where can i find a test kickstart ks.cfg file to see how to setup
dual boot systems, with pre/post actions for both os installs, and
2) is it possible to even have/create a hidden/non visible partition?

thanks

 OK, I'll bite. What is the purpose of the hidden partition ?
