Fatal: Connection to server timed out

Question

Why did a transaction fail with the following error in the transaction log?

Fatal: Connection to server timed out

Environment

All OnApp versions

Answer

Either the server referenced is offline or not accessible from the CP server.

1. Check connectivity from the CP to HV server, if that is ok try to SSH from the CP to HV . It should be that

sudo onapp ssh root@<HV IP>

connects without prompts.

2. If the server mentioned has no resolvers or cannot access the outside world, it could be taking too long to allow the SSH connection:

SSH into the HV

Edit /etc/ssh/sshd_config - set "UseDNS no"

Then restart sshd:

/etc/init.d/sshd restart

If this is regarding a cloudboot server, commands to change the file and restart sshd will need to be added to the custom config.
