...ection is active. Or, in my particular case, I have many routers running OpenWRT, using sshtunnel to establish a persistent connection to my central server. I want to be able to reach systems behind the gateways. I currently have the sshtunnel configuration set up as follows: On the router: ssh StreamLocalBindUnlink=yes -nN -R /sshvpn/gateway-xxxx:127.0.0.1:22 sshvpn at central In this way, should I want to connect to a system behind the router, I can first establish a new SSH connection back to the router itself, from the central server: ssh -o ProxyCommand='socat UNIX:/sshvpn/gateway-xxxx -' -D 108...

...alestyo at scientia.net Hi. AFAIU such options which are allowed for Match blocks are marked with "SSHCFG_ALL" in servconf.c. Going through the list, a number of the is apparently allowed but missing from sshd_config(5): AllowStreamLocalForwarding IPQoS RevokedKeys StreamLocalBindMask StreamLocalBindUnlink TrustedUserCAKeys Could you please add these? I'd have written a patch, but since all my pull requests are apparently generally ignored it's probably just a waste of time :( Cheers, Chris. -- You are receiving this mail because: You are watching the assignee of the bug.

...-R /tmp/.X11-unix/X1:/tmp/.X11-unix/X0 USER at HOST DISPLAY=:1 xterm rm -Iv /tmp/.X11-unix/X1 You have to manually remove /tmp/.X11-unix/X1 afterwards, because SSH doesn't to that and won't create a new socket file on the next connection if the old one still exists. There's a switch StreamLocalBindUnlink=yes but it only works for forwarding the other way around with -L instead of -R. QUESTION: Could this be fixed too? It's quite annoying to delete the socket file manually. Or is there a certain reason why this must not be removed automatically? -- You are receiving this mail because: You are...
