Disable logging to syslog

I am experimenting with aircrack-ng and I managed to fill up / with the syslog file complaining about what I’m doing to the poor wifi card. How can I disable logging to syslog for the duration of my Bash session?. Of course I would like other, unrelated, processes to continue their logging as necessary.

The /var/log/syslog file looks like this, repeating:

Oct 24 03:39:40 loathe NetworkManager[673]: <error> [1445647180.233086] [platform/nm-linux-platform.c:2782] do_chan     ge_link(): platform-linux: do-change-link: failure changing link 4: Unspecific failure (1)

This is on Kubuntu 15.10.

Method 1

syslog is system wide, so you can’t disable syslog on a per session basis.

However, you can

• copy /etc/rsyslog.conf to /tmp/rsyslog.conf
• edit /tmp/rsyslog.conf to remove unwanted logging
• kill rsyslogd (/etc/init.d/rsyslogd stop)
• run rsyslogd -d -f /tmp/rsyslog.conf for the time of your “session”

at the end of the session

• kill rsyslogd (find process with ps)
• run rsyslog (/etc/init.d/rsyslogd start)
