From: Jonathan Burishkin ------------------------------------------------------ History: Server running Ubuntu 10.10 Server Edition straight out of the box, CUPS and SSH. Often throughout the day cant print to laser printer (via cups) from windows laptop untill the computer is rebooted, then after a while of inactivity it fails again. Wrote a cron script to see if it solves issue. crontab -e Code: */10 * * * * sh /scripts/keepalive Script: Code: ping -c 1 192.168.1.1 > /stuff/ping

When it fails, is CUPS still running? Can you leave an SSH session running with "sudo top" (sudo so you can kill processes to recover the box without reboot) up? Dan
