Right, but I've seen the same thing on RH 6.2 with ppp pseudo-devs. Sometimes when I'm setting up a SSH/PPP tunnel between a 6.2 and 7.2 box, when the tunnel is taken down 7.2 will destroy the ppp0 pseudo-dev but it will stay around forever on the 6.2 box. After the box is up for awhile and a number of tunnels have been started/stopped, ifconfig is really messy. ;) The behavior seems to act the same way with tun0 on my -stable box. I start the tunnel, stop it, then tun0 never gets cleaned up. I figure I must be missing the vital piece of information that actually lets the system know it can do the cleanup. I just wasn't sure where to find it. At first I thought pppd just wasn't letting go or something, but there are no tunnel-related processes lying around, no packets flowing, tun0 is 'down', etc. -mrh To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
