[Hosting] Hosting update

[Tanner Lovelace]

Hi folks,

It's been a while since anyone is posted here, but I'd like to 
resurrect this list and use it as a place to discuss the the
new machines that are going in soon.

Currently, we have ldap/kerberos installed on the 1U server
donated by Oculan (moya.trilug.org).  Moya will be going into
the rack tomorrow (Tuesday).  It would have gone in today, but
Bill Ward was kind enough to donate a 60GB drive and the decision
was made to put that in the 1U and set it up as the mail server.
(We might as well make use of the 1GB of ram in the machine.)
I'm currently looking at installing the cyrus imap server
on this machine, primarily because it would make it easy to
store all the mail on the large drive.  If that doesn't work,
I'll look at other options.

Later this week, a new machine donated by the Center for the
Public Domain will be going into the rack.  This machine
(dargo.trilug.org), will be setup as the trilug mirrors.
It holds 9 scsi disks (4 18GB and 5 9GB).  Of the scsi
disks, there are two sets of 3 identical drives.  These
are hooked up to a mylex dac1164 raid controller.  The
other 3 disks are all random disks (2 9GB and 1 18GB) and
are hooked to a Tekram SCSI controller.  At the moment,
the 2 9GB disks are being used for the system (hmm...
I'm trying to remember why we used both... oh well,
it'll come to me later).  The remaining 4 18GB drives
and 3 9GB drives will be setup as a logical volume
and used for the mirrors.  This machine is a full
tower, so we'll probably need to raise the shelf
in the rack that the alphas are currently sitting on.

The other machines we have available are: 
1. Stonesoup - waiting on getting a replacement for
   the 60gb drive that died.  Anyone have any suggestions
   for what to do with it?  Someone suggested a 
   current server, but I think that might work on
   the mirror server, especially since the mirror  
   server is dual PIII-600Mhz.
2. A dell server (dual PII-333Mhz), currently at
   Chris's house.  This machine has no IDE connectors
   but does have 2 4GB scsi disks.  Suggestions for
   what to do with this?
3. Not really a machine, but Bill Ward donated another
   Mylex SCSI RAID card.  Right now we don't have any
   disks to hook up to it, but we should keep this in mind.
4. Bucky and Mudfoot - Two donated alphas.  Jon Carnes had
   a great suggestion for one of these.  I was planning on
   removing them from the rack because they aren't doing
   much, and are seriously underpowered, but Jon suggested
   that we could put one on his network and run another
   name server.  This would be ideal since Jon's
   company's network is on a completely separate network
   from ours.  I think this would be a great use of these
   machines.  Thoughts?

Current plans are to setup the machines like this:

Fatalpha - Shell server.  With the mirrors moved to dargo,
   this will free up room for fatalpha to more easily accomodate
   shell accounts.  We'll probably keep quotas on it, but
   bump them up a bit.  Also, we'll probably take the home
   directories and mount them over nfs (through a private 
   network, more on that later) so they're available on
   the other machines too.
Dargo - Mirror/ftp server.  This will be the mirror server.
   We're finally going to start offering anonymous ftp service,
   but, at least for now, we're going to start it rate limited.
   Trilug users will be able to authenticate, just like now,
   and bypass the rate limitations.  If anyone has suggestions
   for how much bandwidth to apportion for anonymous ftp, please
   let me know. Most likely, normal users will not be allowed
   to log into this box.
Moya - ldap/kerberos/e-mail/imap server.  In addition to being
   the single sign-on server, this will also be the mail server.
   By mounting the home directories here, we'll be able to allow
   users to setup a .procmailrc file so they can do server-side
   mail filtering (yes, cyrus supports this).  Normal users 
   will not be allowed to log into this box.

Like I said above, we're planning on remotely mounting home
directories over nfs.  To make this more secure, we're not
going to do it over the public network.  Instead, all the 
machines have two network ports and will be hooked up to
a second hub in the rack.  This internal network will use
one of the 192.168.n.n networks and NFS will be setup to
only work over that network.  The interface names for
these interfaces will probably be <hostname>.internal.trilug.org.

Okay, that's all I can think about right now.  If you have any
questions about the new setup, please e-mail me (or better 
yet, the hosting list) and let me know.

Thanks,
Tanner Lovelace

 This would be a very good time to hang out with the Open Source 
 people, before they get formally reclassified as a national security 
 threat. -- Bruce Sterling
