Redhat 9.0 newbie questions

[jogle900]

1) What is the command to see what os revision / patch level I am at?

2) Where do I get new patches or service packs for Rehdat 9.0?

3) Is there a built-in firewall with Redhat 9.0?

Any info is appreciated.

Thank you,

1. Issuing [tt]uname -r[/tt] will tell you what revision of the kernel you are running. If you installed the kernel from an rpm, then [tt]rpm -q kernel[/tt] will tell you what kernel revisions are available on the system.

2. You don't. RedHat isn't patching RH9.0 any more. If you want a RedHat-like Linux distribution which is begin patched, try Fedora.

3. There has been a firewall built into the Linux kernel for quite some time now. Older Linux kernels used a technology called ipchains. Newer ones use iptables. RH9 should have iptables available.
