[nycbug-talk] BSD books for admins

[Az]

Hi all
i wanted to buy some books for unix system administration ( multiuser
access, MTA,firewalls, scripting,creating shares,workgroups  etc), is there
anybody who can say something about the following books  or recommend some
other ones ?
 i am new in *nix's  world and  was using freebsd 5.1 in cli mode for a last
2-3 months only.
i need the books  that will teach me  how to do all that stuff  in cli not
gui.
