Servers in my Ubuntu Server

I installed a testing Ubuntu Server on April 3.
Some software or server application are installed on in during last 7 days.
Now I have a worked server which can be put under production environment.
Let’s list the detail information of them.
OS: Ubuntu 6.10
Control Panel: Webmin 1.320
DNS server: Bind 9.32
Web server: Apache 2.0.55
FTP server: ProFTPD Server 1.30
Database server: MySQL version 5.0.24
SSH server: OpenSSH_4.3
SMTP server: Postfix version 2.3.3
POP/IMAP server: Dovecot IMAP/POP3 Server 1.0
Webalizer: Webalizer version 2.01-10
Perl: Perl version 5.8.8
I also install other programs on top of above platform:
Webmail interface: SquirrelMail version 1.4.8

Two applications:

I trust Open-Source is right direction. Let me do more test and know much about it. I will transfer to Linux world.
The first step is to convert server, then for desktop version.
