Hi, I found after repeatably installing Ubuntu minimal 24.04.(1)(2) with rsyslog and the ISPconfig auto install script, that I couldn't read in the ISPConfig panel the syslog messages. After a reboot it worked temporally, but after the daily logrotate the syslog file seemed to be 0 bytes and wouldn't rotate anymore. The server seemed to write then in syslog.1 I removed all the 0 bytes files and did this. The solution, add the line: su root syslog ### Rsyslog and rotation issue ``` sudo vi /etc/logrotate.d/rsyslog ``` Make it like this ``` /var/log/syslog /var/log/mail.log /var/log/kern.log /var/log/auth.log /var/log/user.log /var/log/cron.log { rotate 7 daily missingok notifempty compress delaycompress sharedscripts su root syslog potrotate /usr/lib/rsyslog/rsyslog-rotate endscript } ``` Hopefully it helps somebody. Update 02-03-2025: I found out that now I can read the syslog that the logrotation doens't go well (0 bytes files for all the logs in /etc/logrotate.d/rsyslog). I first removed all the 0 bytes files (these stop rotating). Then I restarted the rsyslog deamon (sudo systemctl restart rsyslog My final solution is/was: sudo rm /etc/logrotate.d/rsyslog The rotation for these logs comes from the file /etc/rsyslog.conf. Those two files where the cause off the issue, so i removed the first one and waited until 00:00 for the rotation > Looks good now.
