I have i dhcp3-client 3.0.3-4 i dhcp3-common 3.0.3-4 My lease time is about 60 minutes. Just last night the dhcp server was down and I got this in my syslog every five minutes: Oct 17 13:18:02 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 5 Oct 17 13:18:07 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 6 Oct 17 13:18:13 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 6 Oct 17 13:18:19 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 11 Oct 17 13:18:30 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 7 Oct 17 13:18:37 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 13 Oct 17 13:18:50 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 13 Oct 17 13:19:03 localhost dhclient: No DHCPOFFERS received. Oct 17 13:19:03 localhost dhclient: No working leases in persistent database - sleeping. After 13 hours, when the dhcp server came alive, the dhclient got the address just like always: Oct 17 13:25:25 localhost dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3 Oct 17 13:25:25 localhost dhclient: DHCPOFFER from vvv.xxx.yyy.zzz Oct 17 13:25:25 localhost dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67 Oct 17 13:25:25 localhost dhclient: DHCPACK from vvv.xxx.yyy.zzz Oct 17 13:25:25 localhost dhclient: bound to vvv.xxx.my.ip -- renewal in 2731 seconds. I'm sorry I can't think of any reason why yours exit while mine goes to sleep. I don't know any config file where that could be adjusted. My /etc/dhclient.conf is pretty much commented out, i.e. the retry and the timeout are the default. > Syslog snippet: > > Oct 17 09:04:19 localhost dhclient: Internet Software Consortium DHCP > Client 2.0pl5 > Oct 17 09:04:19 localhost dhclient: Copyright 1995, 1996, 1997, 1998, > 1999 The Internet Software Consortium. > Oct 17 09:04:19 localhost dhclient: All rights reserved. > Oct 17 09:04:19 localhost dhclient: > Oct 17 09:04:19 localhost dhclient: Please contribute if you find this > software useful. > Oct 17 09:04:19 localhost dhclient: For info, please visit > http://www.isc.org/dhcp-contrib.html > Oct 17 09:04:19 localhost dhclient: > Oct 17 09:04:19 localhost dhclient: sit0: unknown hardware address type 776 > Oct 17 09:04:19 localhost kernel: NETDEV WATCHDOG: eth1: transmit timed out > Oct 17 09:04:19 localhost kernel: eth1: Tx timed out, cable problem?
