[Solved] Ethernet - Multiple incompatible configurations

[lyallp]

I have a gentoo amd64 laptop, with one network interface.

Usually, it's plugged into the office and uses DHCP.

However, occasionally I need to be in a lab environment where DHCP is not available, for reasons I won't go into. I have to setup a fixed IP address, whilst in the lab environment.

I had thought I would just setup an /etc/init.d/net.thelab symlink and update /etc/conf.d/net to reflect the required IP address, netmask and gateway.
Then, I setup a runlevel for thelab which turned of net.eth0 and started net.thelab.
However, this does not work, as the device /dev/thelab does not exist so when I try /etc/init.d/net.thelab start, it fails with a missing device.
Now I could manually create a symlink of /dev/thelab to /dev/eth0 but that seems all too much of a hack.

How should I proceed? Maybe a udev rule?

Any suggestions would be gratefully received

Hi,

any reasons for not using a Networkmanager? wicd e.g. also has a tui interface for non-X.

I found /etc/conf.d/net

fallback entries being the key !

Code: Select all

# General DHCP
config_eth0="dhcp"

# Lab area
fallback_eth0="10.100.100.20 netmask 255.255.255.0"
fallback_routes_eth0="10.2.25.0 netmask 255.255.255.0 via 10.100.100.1"
