short introduction to myself + a (simple) problem
Hello ! I've been subscribed here approx a half year and I now introduce to myself because its the first time I raise a question. I'm running suse linux 6.3 on a pentium 233 with scsi hard disks and a raid compliant controller (too bad that it doesn't run under linux, its an adaptec AAA131U2) But this is not my problem, Since some days, my /var/log/messages shows every 20 minutes following lines, then sometimes it stops a few days doing so and sometimes it start doing it. There is no cronjob except the one which runs a tar command to zip all user homes to a tape drive and also all configuration files and databases. here is what it looks like : Aug 8 00:12:30 mail -- MARK -- Aug 8 00:32:30 mail -- MARK -- Aug 8 00:52:30 mail -- MARK -- Aug 8 01:12:30 mail -- MARK -- Aug 8 01:32:30 mail -- MARK -- Aug 8 01:52:30 mail -- MARK -- Aug 8 02:12:30 mail -- MARK -- mail is the name of the host does anyone have an idea what it could be ? I have this message since I set up this server. I dont think there is something wrong with the system either I don't believe it's service affecting, but I am really interested what this is. Sorry if I posted to the wrong list regards Michael

mail is the name of the host
does anyone have an idea what it could be ?
I suppose it's syslogd The SuSE support database has the solution at: http://sdb.suse.de/sdb/de/html/js_syslog.html jan.meyer

[...] It's not a bug, it's a feature ;-) This message is produced by syslogd and occurs when there's nothing to log at a time of 20 minutes. You can call it the *heartbeat* of your system. You see that the system is alive and if the machine crashes for instance in a power failure you can get the approximated time of the crash. Jan

Exactly. There is a variable in /etc/rc.config which reads SYSLOGD_PARAMS="" changing it to SYSLOGD_PARAMS="-m 0" turns off the marks completely.

It's the heartbeat of the machine. I believe it flushes some buffers too. Add the line: "mark.* /dev/null" to /etc/syslog.conf if you do not want to see it in the logs. regards,
