Hey there to all!

Im currently running RH9 and I need to create 253 virtual ethernet cards!! Redhat calls them aliases not virtual and I believe it's because the ones that are aliased do not use the 802.1q standard, but not positve on this though. So I know you can create aliased ethernet cards in the GUI app redhat-config-network, but this is a very time consuming task. I was wondering if there was a command line app I could write a script around. I know there is a program called vconfig but every time I execute it, it reports that the 802.1q module is not loaded, also it creates the cards as eth1.2 eth1.3 eth1.4 etc... but redhat-config-network creates them as eth1:1 eth1:2 eth1:3 etc.... are theses two types of ethernet aliases the same? And does vonfig do what I need it to?

P.S. I know people are going to ask WHY I'm doing this, I just am! I want to create a 192.168.0.0/16 network off of one box. Yes I know thats big, but thats what I want to do! Each aliased ethernet card will get its own subnet 192.168.x.0.

Thx to all for any answers you give.

Whatever reason you need 254 addresses, here is how you can

#cd /etc/sysconfig/network-scripts
#vi ifcfg-ethx-rangex

IPADDR_START=192.168.0.1
IPADDR_END=192.168.0.254
CLONENUM_START=0

Ok, I understand, and I did think that the network-scripts have something to do with it, but why are you telling me to make the range 192.168.0.1-192.168.0.254? I need 192.168.1.3-192.168.253.3

is it the same trick?
I assume not cause eth1:1's can only have one subnet assigned to them

Assuming eth1 is the card you want to host the entire internet on

#vi ifcfg-eth1-range0
IPADDR_START=192.168.0.1
IPADDR_END=192.168.0.254
CLONENUM_START=0

#vi ifcfg-eth1-range1
IPADDR_START=192.168.1.1
IPADDR_END=192.168.1.254
CLONENUM_START=254

and so on and on.
