Change Interface Name

kidskc · 08-15-2005, 09:59 PM

Hello,
Is there a tool/system call to rename a Network Interface on Redhat linux?
We want to change the names of all the interfaces on our host according to a particular scheme.

For Example,:
Change eth0 to eth0/0 .

Typically, this name is created by the driver. Are there any disadvantages/caveats in Changing the name?

I found a command 'ifrename' on google (This forum doesnt allow me to provide a link). But RedHat doesnt seem to support it.

Thanks,
Kidskc

i beleive you can just change the name of the interface in the ifcfg-eth0 file suing the DEVICE= entry i've not seen anythign using a slash though, any secondary IP's on an interface are typically displayed as eth0:1 not eth0/1 etc...

There shouldn't be any real problems in changing the name, just make usre you really want to do it before you commit to it. sounds like you're trying to replicate the Cisco IOS formats?

Thanks for the reply..

I assume I have to change the file name itself (ifcfg-eth0 to ifcfg-eth0/0) ?? Just changing the Device name in the file doesnt seem to work. Its not able to recognise the card. Need to see if changing the name of the file works..

The name format doesnt matter.. I just used it as an example. But curious, does using the '/' break any existing scripts???

well the scripts are generally distro specific, you might break something though, i wouldn't be suprised really, what with "/" being in there. not somethign i've ever messed with though. I've definitely had a eth0:0 on redhat before though.
