Hi all, currently I am considering writing a patch for OpenSSH that will allow portforwarding using the control_master unix domain socket. The idea is to introduce an extra SSHMUX command, SSHMUX_COMMAND_SOCKS, which will then pass control to the normal socks functions used for dynamic forwarding. The main reason for me to write this patch are: - some more control over who gets to connect to portforwardings. (t...

Hi, (I'm not subscribed to the list, so please CC me on reply.) I'd like to request adding a feature to OpenSSH: Task: ~~~~~ It is quite sometime useful to invoke a program prior to connecting to an ssh server. The most common use case will probably be port knocking. That is a small program sends certain packets to a server and the server reacts to this by unlocking the ssh port, which

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

5.1p1 disconnects after the password prompt when connecting to my router and UPS. 5.1p1 connects fine to other unix hosts, and my Windows client connects fine to 5.1p1 servers. 5.0p1 works fine everywhere. I've tried ssh -T, ssh -t, permutations with ssh -o Compression=no -o TCPKeepAlive=no, etc, to no avail. I've used the default ssh_config file, and it still fails. Can anyone

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config. The problem I find is that the Host pattern is only applied to the argument given on the command line, as outlined in the man page: "The host is the hostname argument given on the command line (i.e. the name is not converted to a canonicalized host name
