kde ksshaskpass ssh-agent plasma

Kubuntu 20.04 LTS

0. keys.

put keys in $HOME/key folder (optional)

make sure private key files permission is 400 or 600. (required), and file extension is ".key".

1. install ksshaskpass (mine is installed)

$ sudo apt install ksshaskpass

2. add keys

$HOME/.config/autostart-scripts/load-keys.sh file content:

#!/bin/bash

export SSH_ASKPASS=/usr/bin/ksshaskpass
SSH_ASKPASS=/usr/bin/ksshaskpass ssh-add ~/key/*.key </dev/null

Run this script manually once. It will ask for password if key file is password-protected, and it can save the password in kwallet so you won't need to input it again.

3. make load-keys.sh executable

$ chmod +x $HOME/.config/autostart-scripts/load-keys.sh

4. load ssh-agent (not required on mine) (make it executable too)

$ cat ~/.config/plasma-workspace/env/ssh-agent-startup.sh
#!/bin/bash
[ -n "$SSH_AGENT_PID" ] || eval "$(ssh-agent -s)"
