I'm a Linux newbie and I'm trying to setup CentOS to do some testing.
I'm aware that CentOS v8 is the latest environment, but my hardware is old and v8 doesn't have the disk drivers where v7 does.
I've configured a static IP on the Centos host and have basic network connectivity (can ping and access yum / Internet)
I've installed and configured SSH but cannot connect to the host and I can't ping it either.
I would appreciate it if someone can explain how to configure the firewall to allow
- incoming ICMP
SSH
I just want to find a straight-forward explanation that applies to Centos v7
Thanks
