That's because the correct key has not yet appeared:

# salt-key --list-all
Accepted Keys:
Denied Keys:
Unaccepted Keys:
ip-65-75-137-152.local
Rejected Keys:

@WrCombs wait.
let me retry that with the correct name

Won't work, the minion has not sent its key yet.

WrCombs

@WrCombs same error occurss

WrCombs

@Romo neither is mine now

@scottalanmiller shouldn't the salt-master have already sent its own key? In my vm the first key I accepted was the key my master.

This could mean there is something else that's wrong don't you think?

Which part? The master? That seems fine.

Romo

@scottalanmiller Yes, on my install the master shows fine on @WrCombs the master doesnt appear.

scottalanmiller

Don't rename the hosts, that's going to lead to more problems.

scottalanmiller

I'm rebooting to test something. For some reason, the Salt Master never showed up in the key list either. This implies something is certainly wrong.

Romo

@WrCombs By the way, do you remember if you did open the ports in the master?

Romo

All set on my install, I hadn't reloaded the firewall rules so that's why my minion could reach the master.

He did, I looked.

scottalanmiller

Here is his firewall...

# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0
  sources: 
  services: dhcpv6-client ssh
  ports: 4505-4506/tcp

Here is the error message on the Salt Master's minion process:

Jan 31 20:32:37 salt salt-minion[901]: [ERROR   ] The Salt Master has cached the public key for this node, this salt minion will wait for 10 seconds before attempting to re-authenticate

That happens to all minions when they are waiting for the master to approve their key.

Yeah, the master didn't have an /etc/hosts entry so it was pointing itself to a different Salt Master. So that was awfully confusing.

scottalanmiller

Ok, so after fixing the hostname on the master, fixing the /etc/hosts file and then checking the errors, we find that that weird ip local address there is NOT from the Minion, but from the Master itself. So the Minion has never checked in at all.
