Cancelling x11 forwarding

[issinoho]

When using an SSH session that has x11 forwarding enabled there are various problems with some basic operations, e.g. connecting to a remote system with key pairs, and (as a consequence) trying to use Git over SSH.

For instance, trying to validate an SSH session with a key pair to something like Bitbucket will result in the following...

Code: Select all

$ ssh -T git@bitbucket.org
x11_request_forwarding: bad authentication data: """
%TCPIP-F-SSH_FATAL, non-specific fatal error condition

And, of course, Git will fail because of this.

I tried using, set display/delete on the session but that seems to have no effect that I can see.

Anyone know how to cancel the x11 forwarding from a live session?

You should be able to set any ssh option by specifying it with -o on the command line, like

Code: Select all

$ ssh -T -o "ForwardX11 no" git@bitbucket.org

That's really useful (and works) but to influence Git a more permanent configuration is required.

This looks to be the ticket, https://unix.stackexchange.com/question ... github-com

Just need to work out how to do this on VMS. I tried the following in SSH$ROOT:[ETC]sshd_config. but doesn't work. Any suggestions?

Code: Select all

Host bitbucket.org
    X11Forwarding no

Your're barking up the wrong tree - sshd_config is the config file for the SSH Server (Daemon). The file you need is the client config file - [.ssh2]config. under your login directory.

Thanks. Looks like [~.ssh2] is not used any more and it's now [~.ssh] so the secret sauce here is to create config. in that folder and add the following.

Code: Select all

Host bitbucket.org
    ForwardX11 no

Host *
    ForwardX11 yes

Thanks for the help.
