Hi, I have two network interfaces in my laptop, rl0 and an0. rl0 is my onboard Ethernet adapter and an0 is a Cisco wireless PCMCIA card.
When I'm at home, there are often times in which I may wish to switch from wireless to wired for performance reasons when transferring files over my LAN. Unfortunately the process to do this, as far as I know, is rather awful. My wireless network is configured with a WEP key and a passphrase. As a result I have attempted to simplify my life by creating a script that I execute when my system boots. It checks to see if my hard-wired ethernet has an IP address, and if not, it grabs one via the wireless card (and sets up the WEP key etc): ------ [EMAIL PROTECTED] /home/adam]$ cat /usr/local/bin/wireless #!/bin/sh # Check to see if we have an Ethernet address on the physical port if ifconfig rl0 | grep 0.0.0.0 then killall dhclient ifconfig an0 wepmode on wepkey mywepkey ssid myssid dhclient an0 mount /data fi ------ It kills dhclient, because I can't run two instances of it at once. This works rather well at the moment, however if I want to switch back from wireless to wired, I have to kill dhclient, config my wireless with 'ifconfig an0 0.0.0.0' and then re-run 'dhclient rl0'. That's really annoying. What I'd like to accomplish is to be able to switch between these two cards automatically. Preferably, I'd like to use wireless as a 'backup' to wired, so that if I am hardwired in, wireless just shouldn't bother trying to obtain an IP address. If I unplug my Ethernet connection, wireless should sync up and take over operations. I was inspired by OS/X's sweetness. It does exactly that; switches between the two interfaces magically. I want some of that sweet stuff. Any idea if the FreeBSD OS itself has any underlying capability for this kind of thing (some sort of Interface watching daemon?) Also, if I configured DHCP to assign the same IP address to both my wireless and wired interfaces, that would possibly mean that any TCP sessions that I have open will stay open, which is really, really cool.
