We finally have our spam filtering back in place at kulish.com. We’ve set it to a semi-aggressive filter where pretty much every incoming email is marked with a spam score.

We’re using the postfix+amavis+clamd+spamassassin setup.

While we’ve been doing without it for a few months (using client side stuff until I found time), I still don’t remember it working this well on the last server install.

Here’s a wopper of an email, just after the installation and testing were completed. The receiving parties and server names have been sanitized to protect the marginally innocent (**PROTECTED**).

Below is a simple database backup script to use with MySQL.

#!/usr/bin/perl -w

use strict;

# Backup – Script used to backup MySQL databases to an NFS share.

# This is a Freebsd 4.x-centric script. It may run on other
# versions of Freebsd, or any other BSD for that matter, but I
# wrote it on a Freebsd 4.7 system. It’s not even guaranteed
# to run on that.

I’ve spent the last few months picking at a FreeBSD clustering project. Well, with some help from BSDHound and the Central Iowa Linux Users Group (CIALUG), it’s finally complete.

I clustered 4 Pentium 133s running FreeBSD 5.1-Release using LAM-MPI for the messaging interface and Ganglia for the monitoring. You can view the statistics here, but you must be registered and signed-in to do so (the pages are fairly graphic intensive).

I believe there will be a clustering How-To posted to BSDHound.com in the future, and if it is, I will be sure to post and update here.

After my fiasco trying to get FBSD to auto mount when the jumpdrive was inserted, I ended up just creating a little perl script to take care of it for now (being finals week and all). It’s not much and does absolutely no error checking, but if anyone has any suggestions, they are more than welcome.

Keep in mind, you must have the proper settings active in your kernel for this to work.

Here it is:

#!/usr/bin/perl -w

use strict;

I made a bad decision that resulted in a non-bootable (to single user only) FreeBSD system. Now I realize that no one really cares what kind of jam I’m in, just like I don’t normally care what kind they are in. But when you have to sit through some ‘open sourcer’ stroke his own ego with the “I know something or where to find it, and you dont. I know its a simple question to answer quickly, but Im just gonna post tidbits of a manpage out of context” attitude, it really irritates me.
