Server Tasks Linux Can Do
Full documentation will not be available right here, but here are some of the server tasks Linux is capable of
  • Apache web server and Postfix SMTP server It comes right out of the box in a default install with both capabilities. For sending mail you no longer need to know the address of your internet provider's SMTP server. As long as you are connected to the internet, you can send mail by entering localhost as your SMTP server, and Postfix will send your mail. No longer are you out at the mercy of your ISP to send mail. For a similar capability in Windows, you'll need to install Windows 2000 (Professional is enough) or NT4 Server (to get IIS and SMTP service which is a part of the IIS package).
  • I've previously gone over its file and print server capabilities on a Windows network, using Samba.
  • It can also run DHCP server, and (within limits) netlogon services. SQL and Oracle database capabilities also exist. It won't fully substitute foe Microsoft Exchange, but then your organization might only need a POP and SMTP server, in which case their deployment in lieu of Exchange can save your organization from a forced deployment of NT Server or 2000 Server which MS-Exchange requires in order to function. Linux is commonly used even in NT organizations as a firewall. Click here for a discussion of firewalls and internet connection sharing
