Check /var/log/messages and /var/log/secure - it should tell you the
problem after a failed ssh authentication.
Often its going to be the permissions are too open on either/all:
Check:
$HOME
$HOME/.ssh
$HOME/.ssh/authorized_keys $HOME/.ssh/id_rsa
Permissions should be:
$HOME/.ssh = drwx------ (owner= full , none othter)
$HOME/.ssh/authorized_keys = -rw------ (owner read-write only)
$HOME/.ssh/id_rsa = -rw------ (owner read-write only)
Also make sure the OEM server is correctly resolving the correct host and
not going out to some other host you didn't expect.
Either way, /var/log/messages, /var/log/secure should tell you what the
problem is.

This one is kind of strange. I have tested ssh from the oem server to the
particular database server in question logged in as oracle, and it works
fine.
However, whenever I try to deploy an agent onto the new database server, I
get this error:
Connection to the SSH daemon (sshd) on the target host failed with the
following error : Too many authentication failures Connection to the SSH
daemon (sshd) on the target host failed with the following error : Too many

I have tested the credentials multiple times from oem and verified that
they are valid. I cant figure out what the issue is. Has anyone run into
this and have any ideas. My next step is probably to try the agent pull,
but I would really like to understand what is going on here.
