SSH Hostname Not Displayed Correctly on Status Right/Left

[kitos9112]

Hello!

I've been going through a few older issues #361 #690

Put simply, I just want to display the full SSH hostname on my status bar.

To simplify troubleshooting I've just set tmux_conf_theme_status_right=" #{hostname_full_ssh} " in ~/.tmux.conf.local

With only 2 panes. I replicated the debug steps stated on https://github.com/gpakosz/.tmux/issues/627#issuecomment-1440661476

In pane 2: Run $ tmux display -p '#{pane_pid} #{pane_tty}'

102938 `/dev/pts/2

Then ssh to a remote host

ssh myremotessh-host.company.net

In pane 1: Run ps -t /dev/ttysYYY -o user=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX -o pid= -o ppid= -o command= And paste the result here

❯  ps -t /dev/pts/2 -o user=myuser -o pid= -o ppid= -o command=
myuser

myuser 3163299 3163296 /usr/bin/sss_ssh_knownhostsproxy -p 22 myremotessh-host.company.net

In Pane 1: Run cut -c3- ~/.tmux.conf | sh -sx _pane_info XXXX /dev/ttysYYY

❯ cut -c3- ~/.tmux.conf | sh -sx _pane_info 102938 /dev/pts/2

Hello @kitos9112,

Can you please share your ~/.ssh/config file? Redact as necessary.

[kitos9112]

Hello @gpakosz 👋🏼!

Yup, here it comes the SSH config that matches the target host

Host *.company.net
    User myUser
    GSSAPIDelegateCredentials yes
    SendEnv LANG LC_*
    HashKnownHosts yes
    GSSAPIAuthentication yes

[kitos9112]

I must add to the above comment that we also add a few custom lines from /etc/ssh/ssh_config

PubkeyAuthentication yes
GlobalKnownHostsFile /var/lib/sss/pubconf/known_hosts
Match exec true
  ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p %h

[gpakosz]

Ah yeah I'm not sure I can make all the ssh introspection work with custom ProxyCommand directives 🤔

[gpakosz]

I'll give it a try but I can't promise an ETA

[gpakosz]

Hmm actually it might be as simple as dealing with #690

Can you please give the gh-718 branch a try?

[kitos9112]

On it. Yup

[kitos9112]

Oh, amazing. It does work!

Any ETA to get those lines rebased into master?
