Tip: SSH Client Issues

Sometime you may see issues such as the following:

Issue 1: Public Key issue

============
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
============

Solution: Look inside the .ssh directory in your home directory. Do you see .ssh/id_rsa.pub? If not, try to get it from your backup or generate a fresh key pair (and pass the public key to your server admin).

Issue 2: ssh config file permission issue

==============
Bad owner or permissions on /home/anil/.ssh/config
fatal: The remote end hung up unexpectedly
==============

Solution: chmod 600 ~/.ssh/config
