[CentOS] Disabling Firewall/iptables on CentOS 7??

I apologize if this has been asked and answered, but I googled and attempted things for several hours today without success. I have a freshly installed CentOS 7 system that I'd like to disable the firewall and all iptables rules. Basically the equivalent of doing iptables -F In a nutshell

[CentOS] kerberized-nfs - any experts out there?

Is anyone on the list using kerberized-nfs on any kind of scale? I've been fighting with this for years. In general, when we have issues with this system, they are random and/or not repeatable. I've had very little luck with community support. I hope I don't offend by saying that! Rather, my

I actually move the default *.repo files and replace them with "". The thing is that Katello turns all the downloaded yum content into a single redhat.repo file and I don't have to install any more *-release-* rpms any more. I would argue that I should not need to install any *-release-*

Re: [CentOS-es] Problema Puertos Firewalld e Iptables.

Wilmer Tienes una confusion, firewalld e iptables son servicios de seguridad diferentes y es mas, no deben convivir juntos. Debes parar y hacer un mask del servicio iptables para que firewalld funcione correctamente. Este link puede orientarte https://www.unixmen.com/iptables-vs-firewalld/
