Description Adi Linden 2000-02-10 17:36:30 EST
Upgraded to sysklogd-1.3.31-14.i386.rpm. After several days of running just
fine syslogd will start putting -- MARK -- messages into the log at 30
minute intervals. After the next logrotate syslogd will put -- MARK --
messages into the log every 30 seconds and switch to report the mark
messages in UTC instead of local time.

This problem is occuring on 2 machines running RedHat Linux 6.1. Both
machines run webservers, mailservers and name servers and are publicly
available. Firewalling prevents access to port 'syslog 514/udp' on both
system. I cannot reproduce the same problem on 2 other machines which are
workstations and behind a IPmasq firewall.

Could this be a security problem?
Comment 1 Bill Nottingham 2000-02-10 18:53:59 EST
Normal behavior - use '-m 0' as args to syslogd to turn it off.
Comment 2 Adi Linden 2000-02-10 19:58:59 EST
I confirmed that syslogd is running with the -m 0 switch. The problem occurs
regardless. Manually restarting syslogd does not resolve the problem.
Reinstalling the RPM with 'rpm -Uvh --force sysklogd-...' and subsequent
rebooting the system will result in normal and expected syslogd operation for a
few days.
Comment 3 Bill Nottingham 2000-02-16 16:22:59 EST
What does rpm -V sysklogd say on a broken system?
Comment 4 Bill Nottingham 2000-06-10 19:43:42 EDT
closed, lack of input.
