Error when ssh-ing

[RobertAudi]

When I ssh to my linode vps I get the following error:

Error: Can't open display: (null)

If I stop using oh-my-zsh the error disapears...

IIRC you have asked in #zsh about this too. Could this be solved?
Otherwise, please provide any additional info that might have came up. Thanks.

I don't know but this issue is definitely caused in some way by oh-my-zsh. The first step would be to locate the source of the error before even thinking of a solution imho.

This might be caused by alias ssh='ssh -X'. There is no X Server on your VPS. Deleting the alias should fix this.

@sorin-ionescu I just checked and ssh is not aliased. So that's not the problem...

[sorin-ionescu]

Check the SSH configuration files as well. It sounds like it's trying to start the X Server.

I checked all the SSH config files that I know of (/etc/ssh/ssh_config and /etc/ssh/sshd_config on my VPS and on my Mac) and I found the following two lines in sshd_config on my VPS:

X11Forwarding yes
X11DisplayOffset 10

I then created the file ~/.ssh/sshd_config on my VPS and added to it the following:

X11Forwarding no

But that didn't fix the problem.

Do you have export DISPLAY=:0.0 by any chance? Google the error message.

Anyway, this is not an OMZ issue, but a ssh-agent issue and should be closed.

[RobertAudi]

ok I found the problem. It was coming from an alias I had set in the git plugin. The alias used xclip which uses X's clipboard. Removing that alias made the error message disappear. The moral is, don't use xclip in OMZ...
