SSH example not working "dial unix: missing address"

[Sam Fourman Jr.]

I am new to golang, and I am trying to run a command remotely via ssh.


I have found a example, but I am confused as to why it wont work, it compiles fine
but I always get this runtime error and I don't understand why?

dial unix: missing address



I think it has to do with the following code,

agentConn, err := net.Dial("unix", os.Getenv("SSH_AUTH_SOCK"))
	if err != nil {
		log.Fatal(err)

	}

here is the full example:

Thank you for any insight.

Works just fine here.

It would seem you haven't exported the SSH_AUTH_SOCK environment variable. Most likely since you are not runnig an ssh agent.

root@0863af494d85:/# env | grep AUTH_SOCK
root@0863af494d85:/# eval $(ssh-agent)
Agent pid 3110
root@0863af494d85:/# env | grep AUTH_SOCK
SSH_AUTH_SOCK=/tmp/ssh-mcGXzz6Gxmwq/agent.3109
root@0863af494d85:/# ssh-add /root/.ssh/id_rsa
Identity added: /root/.ssh/id_rsa (/root/.ssh/id_rsa)

Don't forget to add an SSH key to your agent (otherwise your example will just fail a little later).

That error message is printed when you don't pass an address to Dial.

Can you confirm that you've set SSH_AUTH_SOCK appropriately?

eval 'ssh-agent'

[output]

SSH_AUTH_SOCK=/tmp/ssh-Ond9LaZuIebk/agent.18010; export SSH_AUTH_SOCK;

SSH_AGENT_PID=18011; export SSH_AGENT_PID;

echo Agent pid 18011;

copy and paste the output in terminal again. Its like setting env varaibles.

then run:

ssh-add ~/.ssh/id_rsa

make sure your both rsa keys are there in ~/.ssh/ folder
