Using remote control in tmux through ssh.

[NikoKS]

Hi, I'm trying to use kitty remote control on an ssh'ed server running tmux. Somehow this doesn't seem to be possible.

for example, kitty @ ls works through ssh, works inside tmux, but not inside tmux over ssh.

What I've tried:

1. try running kitty @ ls. keep gives me time out error similar to 2338
2. set to listen on tcp:localhost:12345 socket and do kitty @ --to=tcp:localhost:12345. Keep getting connection refused

Does anyone ever succeed in trying this?

tmux will be filtering out the escape codes kitty uses for remote control, so you cant. As always with tmux issues: https://sw.kovidgoyal.net/kitty/faq.html#i-am-using-tmux-and-have-a-problem

If you really want to do it still, you could tell kitty to listen on a tcp port, forward it to the remote host via ssh and use --to tcp:forwarded-port

Hi Kovid. Thank you very much for your reply.

Unfortunately, I still do need tmux's remote persistence since I'm almost always working on remote system. (Really wish kitty would be able to do this in the future 😉)

Just test using ssh -R option to forward the port and it works!

May I know why it's able to work without port forwarding when not inside tmux?
Also, are you aware of any fatal security flaws doing port forwarding like this?
