:) Another rainy day in southern California, so I thought of sharing this URL.
h**p://linux.opennet.ru/docs/HOWTO/Security-Quickstart-Redhat-HOWTO/appendix.html
The first URL I posted seems to have been taken down, possibly because I hot-linked it.
Here is the original URL and my apologies to the webmaster in Russia.
http://www.tldp.org/HOWTO/Security-Quickstart-Redhat-HOWTO/index.html
I was referring to part 8, but the entire document is a good read!!!
It is well written and easy to follow. Save the page(s) or bookmark the URL. Open a shell and maximize it (you'll need the room for all the output columns) and you can toggle between the shell and the web-page. If you have two machines so much the better.
This tutorial will walk you through the use of "netstat" and how to identify open ports and services and the associated process ID's, helping you find the services. It is a bit dated, but should nevertheless be of help to many. It will also improve your understanding of the power of the command line. There is much more info on this single page...ipchains, iptables, nmap etc.
Remember, if you've been broken into or your host has been compromised :eek: , there are ways to fool netstat and its output, so take this with a grain of salt.
Have fun.
