All,

The system is a Thinkpad laptop running Fedora Core 5. I would like to configure one pcmcia rf card to work on two networks. One of the networks has security configured and requires a key and the other network does not have security configured.

How can one card be configured to optionally support two networks? I would simply like to ifup eth0 to work on the first network and ifup eth1 to work on the second.

Attempts to do this with the configuration tools seem to result in conflicting configurations. The dynamic network alius is confused with the device name. When the card is inserted it is automatically set to device eth0. There does not appear to be a way to configure it to network script eth1.

Alternatly there does not appear to be a way to optionally force configure, insert, etc. a card to a specific device on insertion.

Thanks in advance. - Dan

You can replace your ifcfg-eth0 with a script that presents a menu and asks you which configuration you wish to use at this moment. Would require that you be on one network or the other. Then just call the eth0 configuration you need for which network you want to log into.

You can also assign two IPs to the nic card and use virtual networking. Never tried this myself, I'd post a URL I found with info but don't think I have enough points yet to post URLs. No way to tell. Googling Linux virtual networking brought up several promising topics. This would allow you to be on both networks at the same time. I am certain there are lots of pains involved in the configuration of it Who couldn't use more charactor eh?

There's a good little tutorial on ip alias here: http://www.cyberciti.biz/faqs/2006/0...ew-network.php

You cant use eth1 for a virtual device but you can alias your current nic to an alias with a different ip, Im not sure if it will let you have ip's in different subnets but its worth a try.

your device would be refered to something like eth0:0 eth0:1 etc
ifconfig will return a complete list.

WiFi Radar at http://gnomefiles.org/app.php?soft_id=332 was suggested as a Gnome alternative to KDE's kwifimanager at ubuntuforums.org

Thank you, very interesting.

I installed wifi-radar. It loops on 'eth2', a non existant device.

Where does wifi-radar find devices?

How can wifi-radar be configured to not search this device?

Hopefully then it will report correctly on the nets found.

Thanks, Dan

I can't help you much with wifi-radar I'm afraid. I use kwifimanager in KDE.

Do you have a configuration file for an eth2 at /etc/sysconfig/network-scripts/ifcfg-eth2 perhaps? Else find out where wifi-radar stores settings and see if there is a reference to an eth2 there.

I had thought of that, no files in etc with eth2 in the name.
