Leaning more about Linux skills...

[Marvel Carvalho]

Hi everybody!    My name is Marvel Carvalho.    I work in a company called Portway. We developed systems to HandHeld and Palm platform , and also Sales Administration Systems to Intel platform - with Delphi and Oracle.    I'm interested in setting up a Linux station in our net NT. We want it working as a PROXI server, FTP Server, internal e-mail Server.  I need to learn how to do all of these things. I know that it can take many time. Which is the best way to learn it? Courses / Books / what else????    I'll appreciate your opinion very much...    I'm looking forward to hearing from you.    Marvel Carvalho  Portway - Brazil - SP
