Re: [OCLUG-Tech] is "xargs" really still useful just for limiting command line size?

[James]

All I know is that I have hit the arg list too long error. That was 
redhat-6.x so maybe it was old.

I think it is worth mentioning the solution if they ever run into that problem.

  i'm pretty sure that's not true.


Wildcarding substitutes the full file names of each matching result
of the wildcard on the command line. Thousands of matching
names/paths can easily blow up the buffer.


  but that's the very point i was making ... that once upon a time,
there was limited space to construct a command before running it but,
these days, that limit is clearly much larger.

  in the old days when i wanted to demonstrate this issue happening, i
would run a series of commands that looked like this:

  $ ls /*
  $ ls /*/*
  $ ls /*/*/*
  $ ls /*/*/*/*
  ... etc ...

note how that wildcard expansion blows up pretty quickly; years ago,
that would generate the "Arg list too long" error in a hurry. these
days, though, as long as the wildcard expansion succeeds and the
command is invoked, i believe we can say that we haven't reached that
limit.

  and it's easy to see the length of each expansion:

  $ echo /* | wc -c
  119
  $ echo /*/* | wc -c
  159988
  $ echo /*/*/* | wc -c
  688989
  $ echo /*/*/*/* | wc -c
  3882671
  $

so if i can successfully run:

  $ ls /*/*/*/*

i'm fairly sure i can conclude that a command can be at least 3882671
characters long, can i not?

  IIRC (and i might not), the historical limiting factor for command
line length was the limit of an internal buffer in the shell that was
used to build the command to be run, and it used to be fairly small
(5000 bytes?). these days, i'm fairly sure bash can handle far longer
commands than that.

  now i can see the obvious value of xargs in that it supports a ton
of cool options like defining the delimiter to be used in parsing the
input stream and so on, but WRT simply limiting the command line size,
rather than something like this:

  $ find . -type f -name core | xargs rm -f

i would simply assume i can generate a really long command and write:

  $ rm -f $(find . -type f -name core)

and, yes, there's always "find  -exec rm -f {} \;" and so on. but
does bash these days have any need for simple command line limiting?
and what would that limit be, anyway?

[OCLUG-Tech] Anyone use thinstation and/or xrandr

[Trevor James]

Good Day all

I am trying to set up a PXE client for a VDI project.  We are using the 
ThinStation developer tool.  I very nice tool that builds a very stripped down 
Linux system (less than 1 minute to boot from PXE which is great).

Problem is this:

It is using xrandr to set up the X-Windows (or I assume since it is all the 
graphics setup) but does not see Display Ports properly.  When we boot the 
machine we get video and everything is great, but if you turn off the screen, 
or it goes into suspend mode, or unplug the cable etc, when you turn it back 
on, or plug it back in, no video.  The system seems to be working fine 
otherwise just no video out.

I have tried adding to the configuration file XRANDR_OPTIONS="-addmode DSP-0 
1680x1050_60.00" without success.

Google has been unhelpful, so if anyone has hands on with this sort of thing I 
would appreciate a nudge in the right direction.

[OCLUG-Tech] Looking for a Linux Consultant

[Jeremy James]

Hi sorry for the late reply, however your response was found in my junk mail.

I am not looking for a software developer.

I am looking for someone who can do IT for a Linux based software development 
environment.
The plan is to do software development on  Linux servers from workstations that 
are Windows Bases.  The developed software is then tested on Linux based based 
targets which are also servers but are embedded computers connected to the 
development network via a wireless interface.

I hope that helps.

Using scripts from the net, I followed this path

Create a user "webguy"

mkdir /home/webguy/www_dev

edited /etc/fstab to make it permanent

This redirect worked

Getting the rights/owners and httpd.conf has not worked

I created a group called webusers, and made webguy a member of that group (we 
don't have to keep this, but it is how I got it to work for sftp access)

Lschown 
 chmod

/var/www   root:webusers  770
/var/www/html   root:webusers770

Now webguy can upload, and change files but I go http://myserver/ I get 403

[OCLUG-Tech] SSL not staying after reboot

[Trevor James]

Good Day all.

I hope I am just missing something small, but two days and not much progress.

I had to update the crt for our https server.

I created a new csr, etc... and after installing everything, neither ssh, nor 
https worked.

I think it came down to a bad private key (or an expired private key since I 
cannot remember the exact openssl command I did a year or more ago)

This is a Centos 7 server

So moved everything to a backup folder

In the /etc/pki/tls/certs folder (where all the last certificates were)

openssl genrsa -out myserver.key 2048
restorecon -RvF /et/pki

The restorecon probably was not needed but it will avoid the linux security 
checks.

Do an SSH to my server, can able to login

Reboot

Do an SSH to my server no connection.

So best I can figure the .key file is not staying after a reboot.  Until I fix 
that I don't think I can redo the certificates for my https service.

Any assistance would be appreciated.

Thanks.

Exquilla is free.

I think it uses the webmail interface in Exchange.
But it has stopped working (I think it is Exchange's fault or rather the

The only thing that is supported at my work is running Exchange in the

Every other way of accessing Exchange else is prone to frequent breakages.

Re: [OCLUG-Tech] Set up a SAMBA server

[James, Trevor]

Interfaces I think are best when one has bound multiple IPs to one NIC, or 
multiple NICS.  The Allow/Deny does the same thing for a single NIC machine (my 
2 cents only).

The Firewall is based on exposure of course.  A SOHO, is more than likely 
behind a bridge/router to the internet, so exposure is limited to usually 
192.168.X.X, or local devices.  In this specific case I am have several 
subnets, so blocking everything but what is needed (first rule of security I 
found) means someone from another subnet cannot port scan and try to compromise 
this machine (which should basically become a set it and forget it type 
machine).

8)  Set up the IPTables

a.   Block all ports all networks

b.  Open SAMBA ports on 192.168.1.X

Any input on this would be greatly appreciated.

 Hi James.  Can you do a $ telnet [destination] 25
 from the other lan to the machine?  If you can, then at least it
 shouldn't be a network firewall issue.  If not, can you ping the mail
 machine from the other lan?  If not, perhaps you have a routing
 problem.  Also, you may have smtp configured such that it only pays
 attention to lan connection requests, although that is less likely.

I can't ping the mail machine from the remote LAN but I can SSH to it.
I can telnet to the mail machine from the same LAN it is on.
Could my ISP be blocking me from telnetting to port 25 on the mail machine?

 Bell internet, in terms of outages, although they have a pretty good system
 for letting people know what is going on etc, if you check out their site

 I feel pretty sure I'm being throttled, with the issues I'm having with
 certain sites, and I don't feel that NCF is very likely to do this, so I
 wonder if somewhere else along the line I am having issues - network card
 or OS or whatever are possibilities, but Bell owns the infrastructure, and
 some sites might be routed through other bottlenecks/ control points, so I
 was wondering if others might be throttling my connection sometimes, and my
 guess was that it would be Bell.  They have been doing stuff to try and...
 force the small providers to charge the same prices they do, to kill their
 competitiveness, etc. 

They resell TekSavvy.
Bell turned off all throttling last year (so they say but I believe them).

 I've got a PCIe x16 slot.  If it crashes we know; if it works, I'd
 like to try hooking my antenna up to it and seeing if a quick menu
 config will yield compatibility.  I'm not going to make you sit there
 while I hunt drivers.  I just want to gauge the effort.

 I don't care if you get any channels, I just want to see it not crash. :-)
I had a 2nd PCIe slot so I tried that and it works out of the box.
I use VLC and it works perfectly (probably better than Windows).
I tried Kaffeine (nice interface) but it stutters on the audio.

I didn't like using that slot because I had to disconnect the firewire 
header which blocked the card.
I never use firewire so it's not huge loss.

[OCLUG-Tech] network printer

[James]

I want recommendations for a network printer.
I have a printer so would it just be better to buy a wireless print server?
Maybe I need a new router with a built-in print server.
I don't have a lot of plugs.
Do they make routers with all 3: wireless/VOIP/print server?

 I have a 4 year old Brother 420CN (printer, fax, scanner) that has a
 built in Ethernet server. The current model is about $100. They provide
 Linux CUPS drivers as well as drivers for Mac and Windows. I
 haven't tried using the scanner from Linux yet.

We have one of those at work, and it does work with Linux.

 Before this printer, I bought a new one every year because they
 wore out.

I upgraded the kernel and now it won't boot all the way.
It gives a bunch of grub errors and then continues booting but it hangs on

I am going to try booting from USB.

I'm considering something like this:

There is a model with a hard drive too.

Are there any other distributions that are good for SSD?

Is it a bad idea to buy SSDs drives?

I have an external USB drive so I'm not concerned about storage space on
the machine.

I just need something cheap and portable for web browsing and email.
