two network cards on a server

Hi everyone,

I've got a Linux server on which there are two network cards. One of
the network cards has been configured, and has been running
satisfactorily for a while. I recently plugged in the other network
card and started using it for a different IP address. However, I've
been having persistent problems with that interface. Namely, some of
the time I can't connect to the interface, which seems to go up and
down unpredictably, and floods the system logs with DHCP
requests. Clearly something is badly wrong here, and I am hoping this
is something simple that can be fixed easily.

This typically looks like

Apr 18 15:16:42 florence kernel: e100: eth0: e100_watchdog: link up,
100Mbps, full-duplex

Apr 18 15:16:43 florence dhclient: DHCPDISCOVER on eth0 to
255.255.255.255 port 67 interval 3

Apr 18 15:16:43 florence dhclient: receive_packet failed on eth0:
Network is down

Apr 18 15:16:45 florence dhclient: DHCPDISCOVER on eth0 to
255.255.255.255 port 67 interval 3

Apr 18 15:16:46 florence dhclient: DHCPOFFER from 152.3.172.1

Apr 18 15:16:46 florence dhclient: DHCPREQUEST on eth0 to
255.255.255.255 port 67

Apr 18 15:16:46 florence dhclient: DHCPACK from 152.3.172.1

Apr 18 15:16:46 florence dhclient: bound to 152.3.172.111 -- renewal
in 43200 seconds.

Apr 18 15:16:48 florence dhclient: DHCPREQUEST on eth1 to 152.3.250.61
port 67

Apr 18 15:16:48 florence dhclient: DHCPACK from 152.3.250.61

Apr 18 15:16:48 florence dhclient: bound to 152.3.172.60 -- renewal in
43200 seconds.

Apr 18 15:16:53 florence kernel: eth0: no IPv6 routers present

If any has any ideas about this, please let me know. Please copy me at

if you can past here some logs -- what do you get when you type
ifconfig - and netstat -rn.
from the log that you pasted i can guess that you need to add router
address for your eth0 .
