Are you initiating SSH connections from all these hosts?

If you just need to SSH to these hosts, use a single key and copy the public key only to the hosts you need to connect to. If you don’t want to copy the pubkeys to target hosts, use LDAP + SSSD or certificates.

Then, if you do need to initiate connections from these hosts and use an SSH agent you can forward your agent and SSH to another host

</span><span style="color:#323232;">host1> ssh host2
</span><span style="color:#323232;">host2>
</span>

<pre style="background-color:#ffffff;">
<span style="color:#323232;">client> ssh -A host1
</span><span style="color:#323232;">host1> ssh -A host2
