ssh tunnel warning

[ecerroni]

Although I think it's a configuration server issue I'm posting it here anyway as I think it might be common case I'm looking to solve here:

Every time I try to ssh to the container through the remote host I'm getting the following warning:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the RSA key sent by the remote host is 36:e1:fc:d8:be:10:8a:26:d9:d1:e6:1f:aa:78:cf:93. Please contact your system administrator. Add correct host key in /home/rico/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /home/rico/.ssh/known_hosts:31 remove with: ssh-keygen -f "/home/rico/.ssh/known_hosts" -R [163.172.171.82]:33 RSA host key for [163.172.171.82]:33 has changed and you have requested strict checking. Host key verification failed.

I can't establish the ssh tunnel. Any advice?

Got further with -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no but then the connection closes immediately.

Here there is the error:

This error indicates that /var/run/docker.sock doesn't exist. Did you map it into the container like so /var/run/docker.sock:/var/run/docker.sock ?

[ecerroni]

It worked! You were right, there was a typo in my docker-compose.yml
