ssh.sh is a small wrapper script around ssh to open a ssh connection in tmux.
|
|
|
|
The main purpose of this script is to configure the tmux windows titles with
|
|
the hostnames provided by the ssh command line itself. I have often to connect
|
|
to cloud hosts with crude hostnames I can't remember and therefore I prefer to
|
|
use cnames or hostnames set via .ssh/config - and exactly these names should
|
|
be used for window names in tmux and not set via escape sequences (pane
|
|
titles) from within the target hosts to their crude names.
|
|
|
|
Additionally a map file can be configured which stores styles for tmux panes
|
|
matched by patterns - like in ssh_config the first count matches. This makes
|
|
it easier to see which pane has a ssh connection to which host when e.g. the
|
|
hostnames are the same but from different subdomains.
|
|
|
|
Simply place ssh.sh, ssh.conf and ssh.map into the same directory. It should
|
|
not interfere with existing configs because it starts an own server at an own
|
|
socket with an own session. For testing simply run "sh ssh.sh -c targethost".
|
|
Without arguments it starts a session without ssh and attaches a xterm to it.
|
|
|
|
It can be configured via a shell alias like this:
|
|
```
|
|
alias ssh="sh ~/.tmux/ssh.sh -c"
|
|
```
|
|
I wrote and tested this with OpenBSD's ksh. I guess bash should work too but
|
|
not tested yet.
|
|
|
|
As a lucky OpenBSD user I also use cwm as my preferred window manager. This
|
|
script can also be used with cwm's wonderful "ssh to" dialog by placing the
|
|
following into your .cwmrc:
|
|
```
|
|
command term 'sh -c ". ~/.tmux/ssh.sh -c $1"'
|
|
bind CM-Return xterm
|
|
|
|
# ...to launch the server only with one window with default shell
|
|
bind CM-s 'sh -c ". ~/.tmux/ssh.sh -c"'
|
|
|
|
# ...and if autogroup is preferred
|
|
autogroup 1 "SSH,XTerm"
|
|
|
|
# ...or if you want prefer to use rofi place this into the config
|
|
ssh-command: "sh ~/.tmux/ssh.sh -c {host}";
|
|
```
|
|
Or if you prefer rofi then put this line into .config/rofi/config.rasi:
|
|
```
|
|
ssh-command: "/bin/sh .tmux_ssh/ssh.sh -c {host}";
|
|
```
|
|
|
|
If you have xdotool installed it also focusses the xterm which is attached to
|
|
the session or spawns a new term and reattaches to an existing session.
|
|
|
|
Special thanks go to the OpenBSD developers for providing such a high quality
|
|
and stable operating system and to Nicholas Marriot for tmux - a tool I can't
|
|
work without it and his patience to answer my questions.
|
|
|
|
Enjoy.

With my sample config it looks then like this:
