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
