Proxy server on linux

[ansonng]

Hi All,

I know nothing about linux basically because I am a windows guy. Now my boss want me to setup a proxy server on a linux machine and I am stucked here.

The situation now is we have a linux machine for this purpose and I can see from the login screen it is a red hat 7.3(valhalla). The problem is I dont have the password for to login this machine. I've tried all my ways to obtain the password from the previous engineer who setup this machine but still couldn't get it. Do I have to reinstall? And if I want to do so, which version should I install? Any guide on the net for the installation as I am totally newbie here...

Any help is deeply appreciated.

If you end up re-installing.....stick with RedHat seeing as it's already there. Their site has excellent instructions

Red Hat isn't any better than any other linux distro for use as a firewall. He'll need to write a few routing table rules and a document or two on subnetworking. That's all.

Linux kernel (fully proxy capable) at

http://www.kernel.org

If you are using GRUB

Select kernel that you wish to boot and type e for edit. You will be presented with a list of items in the configuration file for the title you just selected.

Select the line that starts with kernel and type e to edit the line.

Go to the end of the line press the Spacebar and then type single. Press Enter to exit edit mode.

Back at the GRUB screen, type b to boot into single user mode.



If you are using lilo

At the lilo prompt type
linux single


The kernel will load up and you will be in a root shell. Now just use

passwd root
