I've installed two systems with RedHat 9. They both only have console interface.
During the initial installation of the firewall setup process, one system has all the items checked, the other one only has DHCP checked. Both are setup as Medium security level.
I'm trying to access these two servers from via a SSH client.
The server with all items checked has no problem in establishing the connection.
The other server with onlyDCHP checked is having trouble in establishing the connection.
How to release the traffic blocking?
Any helpful instruction would be greatly appreciated
