i like linux a lot and i intent to make linux and networking my career..even though i like linux better than windows(except when watching movies) i would like to keep an open minded attittude..i dont think linux is an answer for every problem..nor can that be said of the all powerful solaris or windows2000..however i would like to get a good picture of the situations in which one OS would fare better over the other..if i where to deploy linux,solaris and windows2000 advanced server as a nameserver or a mailserver or perhaps a web server how would the three perform over a certian period?
when people say that some OS is more stable and robust over others what do they mean(by stable and robust)?
when a machine is brought down for maintenance what all maintenance work is done on such a machine?
if i were to say that windows2000 has better filesystem security in the form of auditing, discretionary access control through ACL's,quotas and also a much sensible structure for groups and group policy compared to the different UNIX systems available would anyone have a point to prove otherwise?
does any of the UNIX OS have ACL's and auditing build into them?
how can i enable my Red Hat Linux 7.0 machine to do use ACL's and auditing,much like windows2000?by the way is it possible?
that was one series of long questions..they have been bothering me for sometime..i hope someone can throw light on them

with regards
