In /etc/pcmcia/network There is a case statement with "start" and "stop" clauses. This script gets called by the cardctl process when it detects a change in pcmcia network devices.
You could add "rmmod MODNAME" there to the "stop" clause for both of the modules you use. Then when you unplug a NIC your Module will be unloaded?? (maybe?) Test it and see. Also, I have had problems with my laptop when doing things like that when in X-windows. Because of DISPLAY ID issues. But you may not have such issues. I don't switch my network config very much unless I am shutting down the box and taking it home. So I have disabled the System V init scripts for almost everything that has to do with the Docked vs. Undocked hardware config and the home vs. office network config. Then in my rc.local script I use mii-tool to figure out which NIC I am using, the onboard, the PCMCIA aironet card, or the docking station NIC, and then I have rc.local copy the correct XF86config, the right modules.conf for the sound config, and the /etc/sysconfig/mouse file and the right /etc/resolv.conf file into place, do a network reload, and then start up the network daemons like sshd ntpd and xfs. I guess if I wanted to not reboot, but change around the NIC's *I* would log out of X, then init 1, do an rmmod -a a few times, then change the network cards and init 3, then log back in and start X. The way I have my laptop set up it handles the reconfigurations for different hardware/net environments very well. -Ben. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
