Re: connect to two different networks

[Walter Neumann <neumann math columbia edu>]

I have found the only way to do this is to stop NetworkManager.

But even with NetworkManager stopped dhcpd keeps running in the background 
and resets my wireless device after a minute or so. So I added the 
following at the end of the script that sets up networking in this 
situation; it repeats relevant bits of the setup and kills itself after 5 
minutes.  Klutzy but it works.

#!/bin/sh
/sbin/service NetworkManager stop
 ...
delay=300
sta=ath0
KEY=abcdefabcdefabcdefabcdef64
ESSID=private
 ...
# Kill the following after $delay seconds
 ( sleep $delay ; killall $0 ) &
# Keep restarting ath0 until dhcpd has finished trying to do things
# with it.
while true; do
 sleep 2
 /sbin/ifconfig ath0|grep $IP ||
   ( /sbin/iwconfig $sta essid $ESSID key $KEY ; /sbin/ifconfig $sta $IP up )
 /sbin/route|grep 192.168.1.1 ||
   (/sbin/ifconfig $sta $IP up; /sbin/route add default gw 192.168.1.1 $sta)
done
