Salt-Minion can't talk to Salt-Master

[DustinB3403]

Well going into the salt master config file you'd have to look and see if it's set correctly.

Just for laughs check the status of setenforce.

Try setting setenforce to permissive or disabled for now and test.

Cool so now you need create an exclusion in setenforce.

I think that was part of it. The other part as not to specify a port to the server in the minions config file.

How do I do that? Help the newb here please.

I don't recall ever needed to configure SELinux.

You'll need to use semanage to allow this.

[DustinB3403]

Here is a decent man page and examples.

Since you're allowing ports through you'd want to do that.

semanage port -a -t http_port_t -p tcp 4505-4506

What would http_port_t translate to? Everything else I understand except that.

@black3dynamite said in Salt-Minion can't talk to Salt-Master:

Will you show the command for adding the firewall rules for 4505-5606?
The reason I'm asking is because if you include --zone=FedoraServer but your active firewall zone is public then that could be the issue.

I've tried a number of commands

firewall-cmd --permanent --zone=trusted --add-port=4505-4506/tcp
firewall-cmd --permanent --zone=default --add-port=4505-4506/tcp
firewall-cmd --permanent --add-port=4505-4506/tcp

In that order, but not all at the same time. I reloaded the firewall and retested between each line.

None of those is expected to work. The default zone is FedoraServer

-t specifies a type of service http_port_t is all "type 80 traffic"

Followup question. Is this a security risk? Do they need to be removed? Or they just won't work?

It's bloating the firewall with rules you don't need.

No, they are just ignored.
