I needed some VMs to be available on a backup node, which I accomplished with the distributed remote block device, or DRBD. My host machine is Debian 6.

Mailscanner cut out on me, without errors in the log. It was only after turning on debug (which prevents backgrounding and it then only processes one batch) that it showed me.

If you want to execute system commands from something like PHP, you need a SUID executable which you can call from your PHP scripts. This is such a script. It could be extended to support parameters for the commands you want to execute, but that would be an enormous security risk, because then anybody can execute any command. If you need something as flexible as that, you need to think about adding some kind of security restrictions, like a list of allowed commands.

When you're installing zimbra in an Ubuntu or Debian machine, it seems it installs the MTA in such a way that command line tools like mail and such don't work. But when you install exim, it conflicts with the postfix in Zimbra.

grml seems like an interesting Debian-based Linux Live CD. It seems interesting because “[it] includes a collection of GNU/Linux software especially for system administrators and users of texttools.”

My attempts to get Xen working right on Debian stable (Lenny) were not really successful. Xen has had some interesting developments and the version in Lenny is just too old. Plus, the debian bootstrap scripts used to create images don't support Ubuntu Maverick... Squeeze (testing) has the newest Xen and deboostrap, so that's cool. I used the AMD64 architecture.

I wanted an Exim server which could send mail on its own without the use of another SMTP server.
