Hi, I'm having a small problem when using ProxyCommand and ExitOnForwardFailure in combination with OpenSSH 5.1 under Ubuntu 8.04. In order to enable multihop scp and port forwarding, I have enabled automatic public key authenticated tunneling from hostA to hostC via hostB using ProxyCommand in my private .ssh/config file on hostA. <end of .ssh/config>: host hostB...

I'm merging my "streamlocal" unix domain socket forwarding patch into 4.4p1 (or rather 20060926 SNAP) and I gather that the ExitOnForwardFailure capability only works for protocol 1.0. Am I misreading things? I was really looking forward to that feature. I noticed when I began fixing a merge reject in channel_request_remote_forwarding(). - Bill

Hello, I just ran upon this problem and couldn't find it in bugzilla. SSH crashes (abort trap) if all of the following conditions are met: (a) option -f is used (crash happens when going to background), (b) reverse port forwarding is set up (option -R), (c) option ExitOnForwardFailure is enabled, (d) there are no actual port-forwarding failures. The problem can be reproduced by running this command: ssh -f -N -R 1234:[::1]:4321 -o ExitOnForwardFailure=yes ::1 Repeatable every time at least on OpenBSD 5.9 and the latest snapshot (July 17th), on amd64/bsd.mp using default...

AFAIK this is all that is needed. But maybe I am missing something. Is there a feature of autossh that I don't get with systemd? --
