Re: [Discuss] Any miners?

[Neil Schelly]

I have a coworker who makes money mining. His strategy is to mine for
the alternative currencies that are still comparatively easy to mine
than BitCoin. Whatever value he earns there gets exchanged for value
in BitCoin. From what I gather, he makes a decently steady side income
from it, though I haven't really probed for details. I suspect it's in
the range of a few thousand dollars a month profit.

Any takers for some computer parts?

to need something here. I live in Merrimack, NH and work in
Manchester, NH, and I can be pretty flexible to drive parts to meet
you. I'd prefer not to see any of this go to waste if someone has a
use for it, but hese are all going to electronics recycling in a week
or so if I don't get any takers.

 Theres a catch. Many of the keyboards look the same on the top, but its

 There are others that look the same but don't have the shape.

 If there are no keyboards, I'm willing to take a system. ;-)

to see if I can get the machine to power up.  The ATX-EPS spec is the
one that has a colorful 24-pin connector and a black/yellow 8-pin
connector.  The ATX-GES spec is a colorful 24-pin connector and a
mostly black/yello 8-pin connector with a gray and red wire thrown in.

Ultimately, LDAP is a database, albeit very different from the more

learning curve to designing LDAP schemas, especially since the rules
defined in there are very different from the hierarchy which is
largely arbitrary organization.  For that reason, I think most people
using LDAP are using out-of-the-box technologies that are based on
LDAP, like Active Directory or contact/login databases, etc.

I also manage LDAP through phpLDAPAdmin, which is very helpful with

 the IP that the Linksys has on the 192.168.0 network?  Or woould it be
 possible to hide the static route from 192.168.0 to 192.168.1 entirely
 in the Netgear's internal routing rules?  (The wireless folks already
 go to the Linksys for routing to 192.168.0, since it's not within their
 local network's netmask.)  Or am I likely to have to hand configure all
 the wired guys with a static route to 192.168.1?

 Or I guess I might be able to connect the routers via downstream ports on
 both, using a cross over cable.  Then I either need to disable DHCP on
 the Linksys (that I'm sure that I can do), or arrange for both DHCP servers
 to specify a 255.255.254.0 netmask, and the Netgear as the router to the
 internet.  (I'd actually like to keep the wireless guys with 192.168.1
 addresses and the wired guys with 192.168.0 addesses, but this is a much
 softer requirement.)

 I'd appreciate comments and (some of the) suggestions.


I've got setups like this and even in my home. That said, I've got wireless 
and wired users in the same subnet in that case.  I would suggest just 
plugging a normal port in each router together. That way, you're using the 
wireless router itself as more of a wireless hub (access point) instead of as 
a router.

If you want to split up the subnet between wired and wireless users, you may 
have to get more creative.  You could certainly give static DHCP assignments 
to MAC addresses that you know are in the wireless segment for example.

Re: Replacement for Yahoo Domains

 Hi,

 My domain kentsjohnson.com is currently hosted by Yahoo Small Business
 Domains. They don't host the actual web site, they just register the
 domain and maintain the DNS entry. Web site access and email are both
 redirected to my ISP account which hosts the actual site and mail
 servers that I use. For this service I pay $35 / year.

 When it works, this is fine. Unfortunately the email forwarding is
 unreliable. Currently mail to [EMAIL PROTECTED] is bouncing with a
 delivery failure notice.

 Can anyone recommend an inexpensive, reliable replacement for this
 service? I don't need or want to pay for site hosting, I just need the
 DNS registration and forwarding.

Re: LDAP from scratch.

[Neil Schelly]

Here's a great generic LDAP resource: http://www.zytrax.com/books/ldap/
It's reference material as well as some overview introductory stuff, but most 
of all, it's got a browseable reference of standard schemas and DNs and all 
that to make it a little easier to find appropriate ones for your needs.

I also use phpLDAPadmin to manage LDAP and it offers a similar browseable 
reference of the installed schemas in your particular setup.

I'd prefer 1U just because I don't really see anything in your description to 
require more.  I hate to waste space, but you didn't list your reasons to 
lean toward 2U, so I can't say for sure.

That said, similar products also have sensors to monitor voltages, current 
draws (assuming that's available through some sort of PDU), door sensors (for 
security), noise levels, and even light levels.  I can see a use for all 
those at least, depending on the environment.  Especially in a remote 
datacenter that is rarely visited, these kind of things can make things much 
easier for an administrator, especially the security ones if it's a 
datacenter operated internally to the company rather than at a collocation

Ultimately, I'm setting up the new Exim server to smarthost everything to the

the domains that the primary MX is responsible for.  That way, it will accept 
mail from anywhere, destined to those domains and if the primary server (the 
smarthost) isn't available, it'll wait until it is.  I'll set the timeouts on 
bounces and such really long, but you should pick something appropriate to 
how long you're willing to buffer email during an outage.

Hope that helps.  What you're really looking for is a secondary MX guide more

all that useful though (see below).  

 http://sourceforge.net/projects/asset-tracker
Has potential - I'll play with it.

Very inflexible, limited selection of attributes and really more intended as a

 http://helpcore.sourceforge.net/
Website is a link to a site that doesn't work.
 http://ascent.sourceforge.net/
Abandonware that didn't get too far.
 https://sourceforge.net/projects/enetman/
Bad website - will have to download a play to see what features it has.
 http://sourceforge.net/projects/nexb
Doesn't actually do asset management, but is a module of an asset management 
project they have planned.
 http://assetmanagement.sourceforge.net/
Development Status  : 1 - Planning 
 http://sourceforge.net/projects/irm/
Decent project, except it doesn't have any ability to change the attributes 
you can store.  This is actually a pretty decent looking package for request 
tracking, task management, etc.

I'm just apparently in a minority looking for an asset manager that *only* 
does asset management, and doesn't compromise that for a bunch of other 
functionality that I'd prefer to stick with Nagios and Request Tracker.  Any 
integration between them, I'd rather just do with cross-links and I'd be 
perfectly satisfied with that.

Well, due to some rather bad development practices here, it's important to 
know the date that a particular installation of our software was built on, 
because development doesn't really have branches or tags in CVS or milestone 
releases or anything.  Instead, whatever is committed into CVS when the 
installation tarball is built is what gets installed.  I know it makes no 
sense and I'd love to change it (as would the developers for that matter), 
but management seems to think it's not worth the investment of time to learn 
how to do things right.  Other than that, specific hardware peripherals, 
firmware revisions, ram types and sizes, slots for more, hard disks, 
brand/model/submodel, OS and version, role within our production 
infrastructure, peers in terms of clustering, wishlist if it's approaching a 
limit of its hardware, date of purchase, number of Us...

That's what I come up with off the top of my head and most of that can be kept

That slight hang would be the timeout of the DNS request.  I'm guessing it's 
about 2 seconds.  If you want more immediate response, I would suggest 
running a local instance of BIND as a caching server.  It can even just 
forward all requests to your primary DNS servers if you'd like.

The benefit of doing this is that you can set more aggressive timeouts on your 
local instance without affecting other users of the real DNS server.  Then, 
your resolv.conf can point to localhost and your nsswitch will fail back to 
files more quickly.

Would that work?

 Just to add more confusion to the mix, or maybe a useful clue, the

is a perfect example a data store that is not relational in nature (whether

for it to be relational).

 In that case, it's really nothing more than a network accessible front

That's what said about network-accessible BDB and exactly what I mean about

Re: Connection Reset By Peer on ssh sessions

 I've got an annoying problem with the new Verizon Fios service.

 If I leave an ssh session open and sits idle for longer than 2-5 minutes,
 it
 is killed with a Connection Reset by Peer error message.

This may not be a Verizon issue at all.  I have always had this problem
with connections through my Netgear router.  Now that I've moved to using
a dedicated router (half-depth server running Linux/iptables), it's not a
problem anymore.

Ultimately, the keepalive stuff ought to work.  It never drops an SSH
connection while in use, so I've done things like 'tail -f
/var/log/messages' or some kind of bash 'while [ 0 ]; do sleep 5; do
something_else;done' loop on the prompt to keep them open longer in the

I can imagine a scenario where this may be helpful to people.  Can't imagine a 
way to misuse that sort of entry, but imagine that a company has a mail 
server on an internal IP address that receives incoming traffic from the 
outside world through NAT.  So that external address gets NAT'd down to the 
internal address.  

Any servers on that internal network that try to send email to their domain, 
looking up the external IP, and try to connect.  Because of the NAT, then 
that may be difficult to route properly.  Even if they can the NAT to 
translate the stream to the mail server, the mail server will likely just 
reply directly to the internal address of the client server because that's 
the source of the incoming connection post-NAT.  This will cause connections 
to fail and hang and all that stuff.

If however, they have an MX record for both the internal and external IP 
addresses and don't setup anything to allow routing from inside to the public 
IPs, then those machines that might try to connect to it will fail to connect 
to the first MX record (the public IP) and fall back to the secondary MX 
record (internal).

It's a hack, but if you don't have good DNS views setup or have difficult 
routing with NAT without the ability to do two-way NAT, then it should work.

 I know Courier supports public folders, though I haven't used it much
 yet. What are the issues with using Courier for public folders that
 makes Cyrus the only option?

Courier has public folders, sorta, but not in the standard usage that IMAP 
users expect.  It won't store message status flags like read, replied, 
forwarded, etc on an individual basis.  Also, rather than ACLs to connect 
users to folders with particular permissions, the users need to be configured 
with the appropriate folder/file permissions on the Maildirs that are holding 
those public folders.

So yes, courier has a public folder implementation, but it's not a very good 
one.  Ultimately, the thing that makes Courier cool in my eyes (Maildir) is a 
very limiting factor when it comes to public folders.

Postfix/Cyrus/etc help

[Neil Schelly]

I'm looking for some book reviews I think.  I'm trying to setup a 
Postfix/Cyrus mail server that will use SpamAssassin, Amavisd, virtual 
domains, LDAP, etc.  I'm familiar with all the parts of this except Postfix 
and Cyrus already and I'm just wading through the documentation of Postfix 
and/or Cyrus trying to make sense of a lot of it.

It could be that I'm a little dense sometimes, but it seems a lot of this 
documentation is very example-based, but if the example doesn't match your 
goal, it's not very helpful.  I find myself jumping from one how-to to 
another in the documentation for each rather than finding a good single 
resource for reference information on each.

I'm wondering if anyone else has particular experience with these tools and 
can recommend a good source for this information.  For example, is the 
O'Reilly book on Postfix a good start? I know it doesn't really cover Cyrus, 
but I'm honestly having more trouble figuring out the Postfix half here since 
it has to incorporate all these other things.

For some perspective, I've always been more of an Exim guy here since it just 
comes with Debian and has always satisfied my needs just fine, but I've been 
thinking that from all I've read, Postfix might be a better choice given all 
the distinct technologies I'm trying to tie together.  Maybe I'm wrong and 
I'd love to hear that too should that be the case ;-)

Re: Requesting ProBIND help

How far does it get?  

When I've setup ProBIND, I've done it with the remote update script.  You 
should be able to follow the steps manually if you use the remote update 
script too and I imagine a similar sort of logic probably works for the local 
update script as well, but I'm not familiar with how it pushes files.

Anyway, for the remote one, login to the server as the user that apache runs 
as.  SSH with key authentication to the user that runs BIND @localhost and 
confirm that you can do that without any prompts.  Try to write to the BIND 
config/zonefiles to ensure you have proper permissions to create/edit files 
there.  Then run rndc to reload the BIND zones and confirm that it works 
properly.  If things aren't working, then one of those steps probably 
required some input (password prompt) or gave an error or something.

Lots of services will check this before establishing a connection, most

 Does it grok views?  That is, when adding/changing/deleting an address
 can it (maybe through rules you specify) make those changes through
 multiple views with appropriate addresses for each view?  Now _that_
 would save me a bunch of time.

That it doesn't do.  It actually doesn't really have any knowledge of
views to begin with.  In my case, I set it up where the DNS servers were
configured with a named.conf that setup the views with include statements
in each. The includes for each view were external/named.conf and
internal/named.conf which went into the subdirectories where ProBIND2
built it's config files.

Ultimately, it doesn't really support views, but so long as you don't

 for cable and one for OTA HD broadcasts (why pay for something which
 is just flying through the air and waiting for a net to be stuck out
 to catch it :)

I have little or no experience with HD, so take this for what it's worth. 
If you live in a place that doesn't get good reception OTA, then don't
bother.  I was at a friends house recently who was showing off his new
HDTV and switched among a few channels showing very pretty pictures.

That said, his reception was poor. So when he flipped to certain stations,
the picture would occasionally hang for a second or two or become very
pixelated and then catch up.  He flipped on a football game to showcase
the sports value and only one audio track was playing.  The commentator
was speaking on the screen, but that whole audio track was just missing.

He said this was pretty typical of HD broadcasts where they were and they
were still waiting to get their cable hookup for HD to fix it.

Re: New member saying 'howdy' --

[Neil Schelly]

 Hello GNHLUG,
Hello Adam,

 I just found out about this LUG through a contact at the NASIOC.com
 boards.
I'm neilschelly on NASIOC, nice to meet you.

 I still consider
 myself fairly new to the area, my fiancee and I have been living here
 since May. I grew up in Southern CT, and so far I am enjoying NH.

I grew up in Cheshire, CT (among other places) - where are you from? My
wife (then fiance) and I moved up here from Worcester probably a year and
a half ago, so I guess we're also kinda new.

 I plan to attend the MerriLUG meetings, and look forward to my first this
 coming Thursday.
Tomorrow's meeting will be the first I'll be able to attend as well (due
to a new job I just started last week).  Looking forward to meeting lots
of new people.

Re: Voip teleophony - Anyone know Packet-8 or others?

[Neil Schelly]

 I recently looked into creating a MythTV box for HD, but unfortunately,
there are no cable-ready receiver cards, so all you can do is receive
and record OTA (over the air) HD broadcasts, so if you wanted to record
say a Discovery HD program, you are SOL.  When WinTV or Hauppage etc
come out with an HD card that can receive HD  cable programs, then that
is when I will be dumping Comcast's DVR box and make my own PVR.

Why wouldn't this work?

Does that only tune OTA broadcasts?

Re: MerriLUG meeting -- books!

[Neil Schelly]

 I just landed myself with a bunch o' books that someone was going to
 throw out(!!).  These include some *nix classics; below is a sampling of
 the better-known titles.  These will be raffled off this evening.  The
 books are in good shape, with the former owner's initials being the most
 obvious bad thing.

 O'Reilly:
 DNS and BIND
 NFS and NIS
 TCP/IP Network Administration
 System Performance Tuning

 And, by-and-large, everyone's favorite overall admin book:
 Unix System Administration Handbook
 [an older edition; not sure which, and the cover's a bit scuffed.]

Those are some nice finds - I'm jealous especially since I still don't
know what happened to my old copy of DNS and BIND.  Alas, my current job
doesn't let me make it to these meetings, but my new one in Nashua in a
couple weeks ought to let me get away and start meeting some of you folk.

Good luck,
-Neil

Re: [OT] Attack of the stupid-bots?

[Neil Schelly]

 Anybody else noticed a sudden flurry of bogus email
 messages from random IP addrs this week.  Malformed
 headers, no message bodies, no Subject: line,
 no payload.  I must have 40 or 50 by now.  Weird...

Yeah, I've been getting them too... SpamAssassin isn't being fooled though.

Re: Toll Booths (Was: Re: [OT] NH protest against HP printers with RFID chips Nov. 5th)

[Neil Schelly]

 I don't think this is true. In nearly all the cases I have seen, they are
 taking existing cash-only booths and making them cash and Fast Lane.
 I have not see one case where they have reduced existing Fast Lane booths
 to
 dual use.

Exits 9 and 10 are often down to only one dedicated FastLane booth, when
they have always had 2 before.  One of the dedicated ones in each case has
switched to usually being a hybrid.  I imagine this is less often the case
in the city if that's where you're talking about.

Any experience with ProBIND?

[Neil Schelly]

I'm wondering if anyone has any experience with using ProBIND (or similar
tools) to manage DNS?  We're looking for a more readily manageable
solution than the spreadsheet we use now at work.  ProBIND seems really
close to what we want, but we also want to be able to simulate split DNS
with views and I can't seem to figure out if ProBIND can do that - seems
that it can't.

I was wondering if anyone had any experience with using it, especially if
you've used it with views.  And does anyone have any particularly
problematic experiences with views?  Seems pretty straightforward to me,
but it'll be my first time deploying it on a large scale.

Re: Laptop HD help

[Neil Schelly]

Have you considered booting the laptop up with a Knoppix disk and
offloading the data to a network share?  Or is the laptop itself dead?

 My brother's laptop HD is dying.. Anybody have a 2.5 to 3.5 HD adapter
 so I can save the day and get the data off the drive..

Re: Some RedHat advice?

[Neil Schelly]

I've found the solution on my own - thanks for the help from those who
offered.  For the curious, essentially, vsftpd has an option called
session_support and doesn't process PAM session modules unless this is
enabled.  In every documentation and FAQ I've found, it's enabled by
default and it wasn't disabled here, but I guess it's plausible that the
Red Hat distribution compiles that with the opposite default or something.
 I set it to YES and it's just working now.

Re: Is a signon to an SSL site from an http:// page secure?

[Neil Schelly]

That's just as secure.  The HTTPS in your location bar means the page
you're on is secure.  In the case of the site you gave, the form itself is
submitting to an HTTPS page, so that data is sent with a request to a
secure server, after that new secure connection is established.  It's
usually more satisfying for people if they can already see the lock icon
in their browser when typing it in, but it really doesn't have much to do
with it.
-N

 I always thought that you needed to be using an https:// page before
 sending user names and passwords to log in. My credit union claims
 this isn't true, and that since clicking the signon button takes you
 to an SSL page, the information typed in is transmitted securely. I
 have my doubts. Here's a portion of their claim, from the front page
 of http://www.navyfcu.org. I'd welcome opinions.

 Your experience online is very important to Navy Federal, and the
 Account Access Sign On is conveniently located on our Navy Federal
 home page. However, you may have recognized that, when you are on the
 home page, the familiar security symbols do not appear in your
 browser to symbolize that the page is secure. In fact, the home page
 itself is informational and not encrypted. Therefore it does not
 display the familiar “Lock” symbol in the bottom right–hand corner,
 nor does the address line begin with https. However, it is “safe” to
 enter your sign-on information from the home page. Your Access
 Number, User ID and Password are not transmitted until you click the
 “Sign On” button. After you click the “Sign On” button, a secure,
 encrypted connection is established between your personal computer’s
 browser and our Navy Federal systems, using Secure Socket Layers
 (SSL). After you click “Sign On”, you can validate that SSL is being
 used by seeing that “https” is displayed at the beginning of the data
 in your browser’s address line.

Re: Fw: PC Mechanic Tip of the Day: Running Windows Software on Linux

 PC Mechanic Tip of the Day
 What do you know about this?  How does it compare to Win4Lin (or other
 hamburger helpers)? Any actual experience with such things?  -Dave E.

I know that Crossover Office is the commercial version of WINE.  I have
experience with WINE, though none recent, so probably none applicable
anymore.   I hear that they are expecting their 0.9 release in September
or something and the major change between now and then will be improving
useability.  I guess that means WINE will have more of the polish that
Crossover Office must have to be worth paying for.

Re: Walmart-Xandors

[Neil Schelly]

 Is the summary that no one has any experience with Xandros, but the
 Microtel PC is probably suitable for an inexpensive desktop?  Sounds
 like it.

Well, I've got experience with Xandros, but not on Walmart PCs.  It's a
good distro in general - makes lots of things nice and easy.  My biggest
qualm with it was that it had it's own peculiar method of automagically
setting up devices that was hard to interfere with.  For the most part of
course, it just works, but I had some odd hardware that didn't play nice
at first, and it took a lot of tooling around to figure out how to work
around it.

On the plus side, there's a strong community of people trying to help out
in the Xandros support forums and they were watched by Xandros support
people chiming in to help often.

I haven't had to reinstall my desktop in years, but were I to try, I'd at
least consider Xandros. I think I'm more likely to get along with Kubuntu
or Mepis, but they're all good-looking, simple-to-setup, Debian-ish
desktops that seem well supported.
