Hello, everyone.

I am new to UNIX, is their a GUI or way to block ping from the outside world. I am not sure as to do I want to block ICMP all?

Hopefully simple, but will work with all solutions.

This is for security reason.

Thanks in advance!

Hello,

I would suggest looking into firewalls for Unix/Linux systems.

IP Filter is a package that provides Firewall and NAT capabilities that works on many Unix/Linux environments:

If you are running Solaris, you may also try the Sun Screen Lite package available at no cost:

Hope it helps.
Good Luck!

Jim
