[SOLVED] eth# changed so I have to run dhcpcd manually?

Hello again everyone.

I borrowed the hdd from my media PC for my son's computer and when Slackware boots I I have to run dhcpcd manually. I do see that it finds and gets an IP for eth1 where the old system got the IP on eth0 so it appears the interface number changed.

I ran netconfig and went through all the steps but I still don't get an IP unless I manually run dhcpcd after login, how can I get it to run and get the IP during boot like normal?

As root, change the beginning part of /etc/rc.d/rc.inet1.conf so it matches the following:

Code:

# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

# Config information for eth1:
IPADDR[1]=""
NETMASK[1]=""
USE_DHCP[1]="yes"
DHCP_HOSTNAME[1]=""

Congratulations, you just found another of the 'improvements' that our ever-loving udev upstream maintainers inflicted on us all to satisfy their use cases but not ours.

Code:

rm /etc/udev/rules.d/70-persistent-net.rules

then reboot. This will make the 'new' ethernet interface eth0 instead of eth1.

Thanks, I see the nic info on the -rules with a mac address and all.

Waiting for him to quit playing Minecraft before I can reboot.

Or just edit the file by hand to make the MAC match the card you want.

Worked fine after the reboot. Eventually he'll get his own drive and I can get mine back.
