I'm trying to tunnel to a remote VM.
I previously used the below command:
ssh -N -p 22 username@1.2.3.4 -o StrictHostKeyChecking=no -L 127.0.0.1:8080:5.6.7.8:443
Something went wrong with the server at the weekend and the SA had to restore the image.
Now when I try to do this I get prompted with the following:
Permission denied, please try again.
username@1.2.3.4's password:
I don't know what this password should be and the SA isn't available. I am able to ssh directly onto 1.2.3.4 using my public key and when on it I can ssh onto 5.6.7.8 with this command:
ssh -A blueboxadmin@5.6.7.8
Is there any way I can use this to tunnel right through. Failing that, is there anything I can setup on 1.2.3.4 that will allow me to tunnel through?
Looks like the ssh key value pair is missing from the remote server.
You will have to copy the entry of you server ssh key (from $HOME/.ssh/id_rsa.pub file) into the remote server's $HOME/.ssh/authorized_keys file. Make sure the key is pasted in a single line. After doing this, you should be able to connect.
