if you are new you need to do some reading, this is a good starting point
I am new to Linux. I want to learn linux networking. How to start? Please guide me.
Thanks in advance.
Bring up a console and start reading man pages. For example, if you want to know more about samba, type "man samba", which will bring up useful documentation about the program.
There are a ton of GREAT books. You might want to read Sam's Teach Yourself Unix in 24 Hours.
