New Network Card - DHCP issues
« on: May 29, 2012, 02:55:31 pm »
Over the weekend I decided to upgrade the internal nic on my core to a 1G intel pro 1000. I edited the rules for eth0 and eth1 so that they pointed to the correct cards, I have my /etc/network/interfaces all set up correctly and when I run ifconfig, everything is setup and ip addresses are as expected. eth0 gets an ip from my service provider and eth1(new intel pro 1000) is set to 192.168.80.1.

My problem is dhcp is no longer working, so none of my MD's boot anymore? Any ideas? Is DHCP tied to the mac address of the nic? And therefore tied to the nic I removed?

thanks for the help,

Kevin

If I understand correctly you now have 2 Pci Nics? Did you disable the onboard?
Whats the contents of /etc/default/dhcp3-server   ?

I pulled a 10/100 pci nic out and replaced it with a 10/100/1000 pci nic in the same pci slot.

The contents of /etc/default/dhcp3-server ?

What does your webadmin look like for the network settings and dhcp?

Thx Karel, my DHCP server was set to eth0, when I set it to eth1 all was well.
