Bug #10196
closed[RHEL7] Modification of ~/.ssh/config in admin node restricts ssh to other nodes.
0%
Description
While setting up Ceph cluster using RHEL7 VMs, I found that modifying ~/.ssh/config file in admin node with details i.e, Host, Hostname and User of other nodes doesn't work and the admin node fails to ssh to other nodes. I checked the details multiple times and found that nothing was wrong in it and without configuring the file, passwordless ssh was working fine. So, I modified the global file /etc/ssh/ssh_config instead with details of other nodes and it worked. Admin node was able to ssh to all other nodes and there were no ssh issues whatsoever.
Modifying /etc/ssh/ssh_config instead might be a better option as it is a global config file for sshd but still the reason why modification of ~/.ssh/config didn't work on RHEL7 might be worth investigating.

Could you please attach the output of ssh in verbose mode when trying to connect to the remote host ? That will show the exact error message you're seeing.

The output of ssh in verbose mode just showed the error "Bad owner or permissions in /home/ceph/.ssh/config". So, the error shows the solution itself which I ignored earlier. It was a just a permission issue. I changed the permission and it started working. I commented out the modifications done in /etc/ssh/ssh_config because it was no more required.
Sorry for filing the bug. Modifying ~/.ssh/config works as expected and there is no need to modify /etc/ssh/ssh_config.
