KeeAgent 0.12.1 on KeePass2 2.47 does not function (Ubuntu 22.04 LTS) - root cause SSH_AUTH_SOCK isn't set #372

Hello, i'm trying to log in to my server using ecdsa-keys, but have still to type my password. So i think KeeAgent will not work as a ssh-agent on my local machine. rsa-Keys does not function also.

Did you correctly set the SSH_AUTH_SOCK environment variable before using ssh?

a101755 commented 1 year ago

Hi, i think that may be the failure. printenv | grep SSH shows nothing. I will look for How to set SSH_AUTH_SOCK and post it here.

Sincerely yours a101755

another indication, that SSH_AUTH_SOCK is not present, is the following answer: ssh-add -l Could not open a connection to your authentication agent.

It is definitivly something wrong in my environment with ssh and ssh-agent and the environment variable SSH_AUTH_SOCK.

Why this? If i start Ubuntu-Linux, additional a shell in my graphical desktop and type in this shell

ps ax | grep ssh 1031 ? Ss 0:00 sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups 2363 ? Ss 0:00 /usr/bin/ssh-agent -s 3510 pts/0 S+ 0:00 grep --color=auto ssh

further env | grep SSH has no output.

After typing eval ssh-agent // manual start of the ssh-agent

and env | grep SSH // the output is _SSH_AUTH_SOCK=/tmp/ssh-XXXXXXhjbGUf/agent.3868 SSH_AGENTPID=3869

At last i start KeePass2 in the "background" with following & keepass2 & [1] 3910

The final step is ssh @xxx.xxx.xxx.xxx with the mandatory configuration ssh-keygen, ssh-copy-id and so on... all works fine_

The open task is to configure ssh in that way, so SSH_AUTH_SOCK is set system-wide. The variable above is only visible in the shell.

But this is another story.

So i will close this issue with many thanks to David. His hint was crucial!!

Please look at this thread. Environment variable SSH_AUTH_SOCK isn't set. I hope someone can help me.
