Firewall questions-activation and stealthing

Post by OldSchool43 » 2018/06/21 15:09:54

Hi guys, I've been using various debian and ubuntu based distros since I started using Linux back in 2015. Now I was curious about trying out CentOS7 as a basic desktop. I've heard that CentOS doesn't have GUFW firewall like the others do and I wanted to know how to activate it. I also was wanting to make the firewall work in 'stealth' mode. When I've installed and tweaked gufw firewall in the past, I always like to go to www.grc.com and run the 'shields up' test to make sure all my ports are in green. Are there any tutorials on how to do that?

CentOS follows RHEL and firewalld is the default firewall in CentOS 7. Many of us hate it and think it's a massive bloated pig and revert to plain old iptables-services. You can find a ufw package in the EPEL (Extra Packages for Enterprise Linux) third party yum repo if that's what you want to use.
CentOS 5 died in March 2017 - migrate NOW!

Sounds interesting, where do I find that repository? Also is there a version of GUFW that can be used with it?
