Re: [PLUG] UNIX administration survey
|
I'm sorry, I should have re-phrased the question. I wanted to
say too many things in a short sentence.
I really just wanted to know what UNIX/Linux programs people
were running on their network and why. However, I realize that
this would normally take much too long to explain so I just said
"administrative tools", while adding Samba, LDAP, etc into the
mix in the hopes that someone would mention them specifically.
I'm sorry about that, but I'm very cut-off from the Linux world
because my office is heavily Windows oriented.
If you have any input that you believe could be helpful to my
knowledge quest please do. I appreciate it very much. Thanks
Brent
