Problem with my ssh session

james80 · 1 February 2024 18:19

HI,

I’M from linux mint and pop OS, and usualy to open my ssh session without having to add everytimes my passphrase, I always use a script in bashrc, so when I start a new session I just have to enter one my pass, but with garuda, when I open the session with konsole, I don’t receive the passphrase asking, do you know why? Maybe I have to do something else with garuda?
thanks

here the script:

if [ ! -S ~/.ssh/ssh_auth_sock ]; then
  eval `ssh-agent`
  ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock
fi
export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock
ssh-add -l > /dev/null || ssh-add

here we go, sorry

Most likely not the root cause of your problem, but that symbol means that a reboot is pending after an update.

After that, you should probably investigate this

Additionally, rather than bashrc, I think you should use config.fish, because fish is the shell we use here by default.
I can’t help you much here, but give a look at this hint and, if necessary, the linked Arch wiki article.

if [ ! -S ~/.ssh/ssh_auth_sock ]; then
  eval `ssh-agent`
  ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock
fi
export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock
ssh-add -l > /dev/null || ssh-add

What you are setting up is ssh agent and making it share a single session so that other terminals can use it as well. The only problem is you are setting it up for bash and garuda by default uses fish.

Go to,

~/.config/fish/config.fish

Put this at the end of file

if ! pgrep -u "$USER" ssh-agent > /dev/null;
    ssh-agent -c -t 1h > "$XDG_RUNTIME_DIR/ssh-agent.env"
end
if [ ! -f "$SSH_AUTH_SOCK" ];
    source "$XDG_RUNTIME_DIR/ssh-agent.env" >/dev/null
end

Save it exit it and open a new terminal.

Please note the -t 1h ensures that ssh agent only holds identities for a max time of 1h i.e. you would be asked to enter password again after an hour has passed. I do this for better security you can remove this flag if you want.

In new terminal type

ssh-add

This will prompt you to enter password for the ssh id you have created and add it to ssh-agent. Once done ssh session’s won’t request passwords unless the ssh-agent expires (due to -t flag) or you reboot.

You can

ssh-add -l

To see the identites ssh-agent currently has.

thank you very much, but ssh-add does not work, my script was about .ssh with my id_ed25519 key, but I guess I need to copy that to .config/fish ?

ssh-add
Could not open a connection to your authentication agent.

I added in config.fish

## Run fastfetch if session is interactive
if status --is-interactive && type -q fastfetch
fastfetch --load-config dr460nized
end

if ! pgrep -u "$USER" ssh-agent > /dev/null;
ssh-agent -c -t 1h > "$XDG_RUNTIME_DIR/ssh-agent.env"
end
if [ ! -f "$SSH_AUTH_SOCK" ];
source "$XDG_RUNTIME_DIR/ssh-agent.env" >/dev/null
end

james80 · 1 February 2024 22:03

do you know what it could be?

NaN · 1 February 2024 22:06

Did you open a new terminal after adding that to config.fish? Because it says ssh-agent is not available.

It’s your system. Help yourself.

Either of

systemctl status [email protected]

Or

journalctl --grep [email protected]

Would show you what’s going on.

james80 · 1 February 2024 22:31

yes, but seems to work now after reboot

BluishHumility · 3 February 2024 00:28

OpenSSH includes a user service that takes care of this for you. You just need to set the SSH_AUTH_SOCK="$XDG_RUNTIME_DIR/ssh-agent.socket" environment variable somewhere (in ~/.profile is fine) and enable the service.

systemctl --user enable --now ssh-agent.service
