I created a shitty Python script to manage multiple SSH connections because I couldnt find a decent one
ryannathans, Wrap a nice ssh config manager around kitty ssh sw.kovidgoyal.net/kitty/kittens/ssh/ and it’d be pretty slick
axum, 
Multiple ssh connections should really just be managed using Ansible.
Oha, isnt ansible a tool for automatically deploying stuff?
falsem, Configuration management.
heartsofwar, (edited ) Given how the python script is written; I doubt this was meant for linux… because its completely unnecessary on Linux: man SSH config
More power to you though!
Illecors, ☝️
Oha, (edited ) I doubt this was meant for linux…
It is. You cant get ssh to print out a nice list afaik.
heartsofwar, I showed you how… read on how to setup an SSH config… its completely possible
aard, 
You have a list of systems you’ve connected to in known_hosts, though. And the config file is easy enough to parse - throwing away the stuff you don’t care about - to expand on that list.
Oha, I could add a import from known_hosts option or something like that
aard, I assume you mean “lookup”, as import doesn’t really make much sense.
I’m currently using this with wofi, though I’ll eventually rewrite it as anyrun plugin, which provides a bit more control:

zacher_glachl, (edited ) I can (and do) just read the
~/ssh/.configfile if needed, it’s quite legible. In most cases however zsh autocompletion does all the heavy lifting for me (ssh ser(tab) -> ssh servername).Still a cool idea for a script, and if it works well for you more power to you, just saying there’s more ergonomic and universally applicable solutions. (Only mentioning this since you said “I couldn’t find a decent solution to this problem”).
forwardvoid, Great attempt on making a tool, I think your usecase might not be as appealing to others. If I need to list the hosts I have config for I would use: grep Host ~/.ssh/config If your list of servers is too long to remember, you might want to look at Ansible for configuration. But whatever works for you :)
ShortN0te, Just on the side, Openssh and ssh config works just as well on Windows.
