redhat firewall

[littlevito]

I'm using redhat 7.2, and somebody told me that in order to get sendmail to listen to the internet at large, I have to deactivate the firewall. I was wondering how I would go about this, or if I need to do something different. Thank you very much in advance.

I'm using Redhat 7.3, but I think the solution is the same for 7.2. To deactivate your firewall do the following:

as root, run the setup program, on my computer it's located at /usr/sbin/setup. When you start the program you get a menu where you can choose firewall configuration and then you can disable your firewall.

Hopes this helps!

In redahat 7.3 you can also type "lokkit" as root to go straight to the firewall config.

thanks, i used both of thos programs, but after i exit, it isn't updated. every time i return to lokkit, the firewall as back set to High. How do i get it to save the settings? thanks for the information you already gave

I think it does save the settings, it just doesnt show your current settings when you run it again.
I turned set it to high on a server and couldnt access any webpages, when it was turned off it all worked fine. But everytime i ran it, it showed itself as set to high.

You never want to turn off the firewall to let a program have access (unless you are trouble shooting). You should be looking into opening the ports to allow connections to that box or service. If RH is stilling using ipchains for the firewall I can't help you There might be a NHF on ipchains.
If they starting using iptables then there hundreds of posts in LNO to explain how to open ports and forward traffic to your mail server.
