After having nightmares preying on my fears of the unlikely case of my online unstable box compromised I thought I would take a look at Epylog after Walter’s post.

It does not seem to have a debian package so I applied alien to convert rpm to deb and checked its contents, then installed the package. So far, so good.

Edited quite a few files to get it working for my debian system. RH’s secure to auth.log and maillog to mail.log, and in the process I became familiar with the configuration files.

What a mess.

Python type syntax here, config.ini style there and XML stuff throw in for good measure. Sweet baby J. What ever happened to one line files like passwd? Compromise: please use python syntax!

The HTML log files it generates could be much better. Not sure what templating engine they’ve decided to use. Seemingly not htmltmpl which I have bothered to learn. :/

Urgh, I can’t be arsed to log iptables traffic.

When you run epylog, the console output is quite cool (esp. the parsing bit):

Although it would be better if it just gave me the report on the console.

If I was a paid sysadmin I would defn. contribute to this project. There is lots to do. I would like a simple network traffic breakdown. I tried cacti with SNMP and RRDtool or something sometime ago. Nightmare.

I’ll run epylog cron jobs for a few days before I remove it…

Is a service to check what ports are open on my machine (from the outside)? I am not allowed to run nmap from school and I am using putty from my landlord’s Win98 machine.

Found any of my content interesting or useful?
