Hello there

I am a Windows NT Network Administrator "MCSE" now i would like to extend my
skill & go for Linux Administration. now the question is that does my
being an Nt administrator help me in any way with Linux.?
Also what should i know to be a good Linux Admin ? I heard linux users have
to
do a lots of  programing too do i have to do that as well ?

thankyou
