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,

Numerous how-tos all over the Internet show how one would set up a tunnel using ssh, e.g.: ssh -f -o Tunnel=ethernet <server_ip> true I was wondering if there's a way to subsequently acquire the names of the local and remote tun/tap interfaces (e.g., using the default "-w any:any") for subsequent automatic tunnel configuration, e.g.: ip link set $TapDev up ip link set

Hi, I have a problem with a Linux box which I updated from 2.5.2p2 to 2.9p2 recently. It's running a tunnel started via inittab using a script which starts ssh -2 -N -o 'ConnectionAttempts 3600' -L <tunnel> $host This has run reliable with 2.5.2 over the last months. Now, after I have upgraded to 2.9p2, the tunnel is closed right after each attempt of an application to use

...things if you're using both. Specifically, ssh -W host:port with ControlPersist enabled opens up two connections to host:port and sends data from both back. I think this is happening because channel_connect_stdio_fwd is being called twice, once in client_setup_stdio_fwd, which is called from ssh_init_forwarding, and once in process_mux_stdio_fwd, which is called once the client process starts talking to the master process. It looks like the way ControlPersist is implemented, the process forks, with the child becoming the master process and the child making its connection through that. Thus, it seems li...
