Ubuntu – Huge citadel log files

citadeldisk-space-utilizationlog-filesloggingUbuntu

I noticed today that my mysql server was not starting up anymore. Checking the error logs, it showed that it didn't have enough disk space. I thought that's really weird since there's nothing on my server that could possibly take up 30GB. After digging around I observed my citadel logs are taking up a massive 22GB of space in the /var/lib/citadel/data/ directory:

This is split in lots of smaller (still big) log files:

Why is this happening and how can I prevent it in the future?

EDIT: Here's a sanitized sample of one of the log files:

They're database logs. Citadel has functionality to delete them. Just turn on automatic log pruning and the logs that are committed to the database will go away.

This means people are trying to brute-force your passwords (common on any public-facing server).

It shouldn't cause any harm to clear out this file.

One way to reduce this is to change the port for SSH from 22 to something arbitrary. For some additional security, DenyHosts can block login attempts after a certain number of failures. I'd highly recommend installing and configuring it.

Following the intruction on this link made the setup work correctly.

http://www.ducky-pond.com/posts/2012/Jul/installing-citadel-on-rpi/

sudo mkdir /etc/citadel/netconfigs
sudo chown citadel:citadel /etc/citadel/netconfigs
sudo service citadel restart


sudo /usr/lib/citadel-server/setup

Then you will need to edit /etc/init.d/webcit, and put this just after #/bin/sh (If it is missing)

### BEGIN INIT INFO
# Provides:  webcit
# Required-Start:
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start daemon at boot time
# Description: Enable service provided by daemon.
### END INIT INFO
