We have a newsletter that goes out to our petstore members
every morning. Some people complained that they were not getting
the newsletter so the first thing that i checked was the maillog.
I checked the sendmail maillog for an email address that
was supposed to get the newsletter and i saw that sendmail never sent that
email.

Implementing Disk Quotas on Linux
This tutorial walks you through implementing disk quotas for both
users and groups on Linux, using a virtual filesystem, which is a
filesystem created from a disk file. Since quotas work on a per-filesystem basis,
this is a way to implement quotas on a sub-section, or even multiple
subsections of your drive, without reformatting. This tutorial also
covers quotactl, or quota’s C interface, by way of an example program that can store
disk usage in a SQLite database for monitoring data usage over time.

The Requisite Disclaimer: If you are on a different hosting company, I cannot guarantee this tutorial will work for you (though it may be helpful in figuring out your issues). As always, before you make changes to critical files (http.conf, .bashrc, etc.), do yourself a favor and make a backup copy; this tutorial offers assistance, but no warranty, so if you mess something up during the install, you’re on your own (but Westhost tech support should be helpful). Finally, this tutorial assumes some familiarity with the Site Manager from Westhost and some basic knowledge of the Linux shell.

There are times when you’re looking for a particular library, or file, which you know is available to Debian but you cannot find the package which contains it. This is the kind of job that the Debian packages site helped with in the past, but given its current unavailability we’ll look at another approach.
Finding the package which has installed a particular file upon your system is accomplished via the dpkg command. This can be used as follows:

With the introduction of the Apache2 packages in Debian it is much simpler to create and use a secure SSL protected webserver than in the old days with Apache 1.3, here we’ll show how it is done.
If you have Apache 2.x installed already then you’re good to go as you don’t need anything extra installed.

Recently I inheritted ownership of an SVN server which was misbehaving. Trying to determine why it wasn’t working correctly involved a few hours of testing, careful thought, and caffeine. Eventually I got it working correctly using the often-overlooked tool strace.
strace is a common tool upon many GNU/Linux systems including Debian. Put simply strace is a “system call tracer” - which is where it gets its name from.
Using strace, as root, you can monitor the system calls made by any process upon your system. This can be enormously beneficial when you have a misbehaving program.

If you have control over your DNS you can setup ‘wildcard hosting’, which means you can have a webserver accept connections for any given subdomain. This can be enormously useful for community websites, or other hosting purposes.

One of the most common Apache2 questions I’ve seen on Debian mailing lists is from users who wonder how to host multiple websites with a single server. This is very straightforward, especially with the additional tools the Debian package provides.
We’ve previously discussed some of the tools which are included in the Apache2 package, but what we didn’t do was show they’re used from start to finish.
