Not displaying `hostname_ssh` in status bar (macOS Sonoma)

[ww7]

Hi, on macOS (latest 'Sonoma') resolving of SSH hostname is not working. Printing empty value for hostname_full_ssh, hostname_ssh and hostname

At the same time, function ssh_or_mosh_args seems works: ssh -G $ssh_or_mosh_args 2>/dev/null | awk '/^hostname / { print $2; exit }' – printing correct remote hostname

---

I tried to debug as gpakosz#627

pane_info='25239:ww7:zsh (cwterm)' – seems no SSH process associated with that TTY

Before SSH connect, based on tmux display -p '#{pane_pid} #{b:pane_tty} false false #h #D' log:

Hello @ww7 👋

Works for me on Sonoma.

There's an error in the command you tried:

ps: /dev/tty5 and /dev/5: No such file or directory

• Can you please first to try a fresh install of Oh my tmux! ?

• Then with only two panes do the following, let's name them pane 1 and pane 2

  • In pane 2:
  • Run $ tmux display -p '#{pane_tty}' → This will display a value like /dev/ttysYYY
  • Then ssh to a remote host
  • In pane 1:
    • Run ps -t /dev/ttysYYY -o user=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX -o pid= -o ppid= -o command=
    • And paste the result here

Hello @gpakosz !

Thank you for the kind answer! As it works on your side with Sonoma then I should fix it on my side.

There's an error in the command you tried:

ps: /dev/tty5 and /dev/5: No such file or directory

^ sorry, this error is my mistake, it some wrong run.

Test shows SSH process associated with TTY. Before and after SSH session it shows only:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
ww7                             57084 56766 zsh (cwterm)

I'm using sorin-ionescu/prezto Zsh configuration framework and seems some additional customization made this issue possible.

Empty Zsh and fresh setup of Prezto works fine with Oh my tmux!

Great thanks and sorry for disturbing! :)
