I've been testing tunneling on Linux with openssh-SNAP-20060116.tar.gz and found a problem. When I use LocalCommand for doing ifconfig stuff, the command line was executed before a tunneling interface is opened. This causes errors on Linux and the interface is not automatically set up. This is not a problem on *BSD because you can do ifconfig for unopened tun/tap interfaces. But in Linux,

...couple cases where it would be nice to use LocalCommand to run something to setup a session in some way when using ControlMaster. For example, to scp something or do an sshfs mount automatically once your session is established using the control socket. However, in 4.7, LocalCommand is run before ssh_control_listener. It's not terribly hard to work around (fork and sleep first in the command), but is there some reason these couldn't be swapped? (I see some discussion about LocalCommand and tunneling from last year which wanted to move it earlier, but it doesn't seem this was done.) :-Dylan
