i need to make myself more clear. i want to know the general knowledge about using unix platform as web service platform.
apache only covers the web server part.
there are ftp server, telnet server (or ssh), mail server, security and server user management etc. and other operations such as package install etc.
As well as Unix Server management through the Unix command line.
While I was on the linux (Sun Cobalt), it offeres a simple Web Access User Interface to do some of the server management works, but for a pure Unix Box I am going to use, I think everything is from command line.
