I've been playing around with this sort of setup, too, where I want a command line to change from wired to wireless (at the same IP address, even) and back again. I haven't found the magic solution, particularly one that doesn't have a lot of hardcoded network config in it. I'm also somewhat ticked that "route flush" doesn't really flush all routes like the man page says. 8-) Eventually, I usually arrive at a point where I can't find my way back and have to reboot to get some work done. Some things I've been using are "route delete <my ip address>" and "route add -ifp <interface> default". Might be a good idea to "arp -a -d", too. -- J. Porter Clark <jpc@porterclark.com>
