Apress' Pro Ubuntu Server Administration is described by its author, Sander van Vugt, as the best book he's ever written; he should know — it's his fourtysecond book.
The table of contents is mouth-watering: server installation, system imaging, performance monitoring and optimization, file system management, network monitoring, SAN, configuring OpenLDAP, integrating Samba, adding a mail server, [...]
I was delighted to receive a copy of The Definitive Guide to SUSE Linux Enterprise Server by Sander van Vugt, because of two things: first of all, I greatly enjoyed another book by the same author (Pro Novell Open Enterprise Server), and second I'm feverishly working on a project which will ultimately be based on [...]
I can smell it coming.
Let us rid ourselves of all that OpenLDAP stuff and implement Microsoft Active Directory instead; if others do it, we can't go wrong can we? And while we are at it, who needs Lotus Domino? Let us use Microsoft Exchange with Microsoft Office. Oh, and Linux? Nah!
I'm not religious, but [...]
I spend a good part of my time ensuring that whatever services we offer will be up and running 24/7. Be it an Exim cluster, a failsafe BlackBerry Enterprise Server, MySQL on DRBD, multiple DNS servers, LDAP directory servers, you name it: whatever services we offer are very hard to kill.

We've been running DRBD, the Distributed Replicated Block Device on two pairs of machines for over six months now, without a single glitch. As predicted, the support contract was unnecessary.
The first cluster (for which the contract was purchased) runs a couple of mail servers, with Exim, Dovecot and OpenLDAP on them and has [...]
We've had very good experiences with DRBD, the Distributed Replicated Block Device which we've had running on a pair of machines for a couple of months now. So good in fact, that we invested in another pair of machines to run a similar setup for a good number of MySQL databases used internally.
I have [...]
The mail server for 500 users "I mentioned recently":http://blog.fupps.com/2005/11/04/high-availability/ is ready to rumble. It runs on "CentOS 4.2":http://www.centos.org/ and "uses DRBD":http://blog.fupps.com/2005/12/15/drbd-cluster/ to replicate a 500 Gig file system from a master to a hot-standby machine. These two are crosslinked with Gigabit Ethernet. "heartbeat":http://www.linux-ha.org/ uses that same link as well as a dedicated serial link to [...]
The main clients or MUA(Mail User Agent) for our e-mail cluster will be Mozilla Thunderbird and a web based program. I am currently in the process of creating an automated setup for _Thunderbird_ which will allow an end-user to run a small program, enter some credentials and get a user.js file generated and set up [...]
