We are running about 200 HP servers (mostly Linsux unfortunatly) but we use the serial console on some specific servers where kernel modules could fence the box and if that happens nothing will be still written to the syslog (local or remote). So we use serial console and conserver to log such things. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204 You can find my resume at: http://www.Alameda.net/~ulf/resume.html
