I had a similar problem for a while on one of my Debian boxes with early series 2.4.x kernels. It had nothing to do with DHCP, as I wasn't running any DHCP at the time on my net. My workaround was a cron job run every five minutes which bounced the card if I was unable to ping my firewall: #!/bin/bash ping -q -c1 firewall 2>&1 >/dev/null && exit 0 logger -t ifbounce -p kern.warn "Bouncing eth0" /sbin/ifdown --force eth0 /sbin/ifup --force eth0 The machine in question has a Linksys EtherFast 10/100 (tulip chipset) NIC in it. The problem does not occur anymore, using a recent 2.4.x kernel. Of course, this may not even be the same problem. -- $ fortune -m Kellen -------------- next part -------------- A non-text attachment was scrubbed...
