How To Enable SSH in Linux Mint
Troubleshooting
(somebody remind me to clean this crap up & make it easier to follow...)
If you get crap like:
Warning: the ECDSA host key for '<snip>' differs from the key for the IP address '<snip>' Offending key for IP in /home/<snip>/.ssh/known_hosts:14 Matching host key in /home/<snip>/.ssh/known_hosts:12 Are you sure you want to continue connecting (yes/no)?
or maybe:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 SHA256:'<snip>' Please contact your system administrator. Add correct host key in /home/user/.ssh/known_hosts to get rid of this message. Offending RSA key in /home/user/.ssh/known_hosts:102 remove with: ssh-keygen -f "/home/user/.ssh/known_hosts" -R '<snip>' RSA host key for '<snip>' has changed and you have requested strict checking. Host key verification failed.
when you try to ssh to a machine...
sudo ssh-keygen -f ~/.ssh/known_hosts -R HOSTIP
Messages like:
Warning: the RSA host key for '<snip>' differs from the key for the IP address '<snip>' Offending key for IP in /home/user/.ssh/known_hosts:102 Matching host key in /home/user/.ssh/known_hosts:103 Are you sure you want to continue connecting (yes/no)?
mean that you have an extra entry in your known_hosts file & indicates the line you want to delete...
If you see:
Failed to add the host to the list of known hosts (/Users/USER/.ssh/known_hosts).
Check permissions & ownership on that file...
