Introduction
Linux is the perfect choice for an operating system on which to build anetwork server. Much of the fame of Linux as a server system comes fromits widespread use as a system on which Apache web servers are built.But the power and reliability of Linux does more than provide a stableplatform for the world’s most popular web server. Linux provides all ofthe most important network services in a single low−cost package.
Low cost, reliability, and power are propelling the continued growthof Linux as a server system. Linux has proven to be a cost−effectivealternative to high−cost Unix servers. And it has proven itself to bemore powerful and reliable than any proprietary desktop operatingsystem trying to recast itself as a server operating system. Salespeople might lust after the vast desktop market, but as professionalsystem administrators, we know that the real technical action is withthe server systems.
The tremendous range of network services provided by Linux meansthat it can be used for all of your network server needs. In this book,servers are categorized as “Internet servers” and “departmentalservers.” This somewhat arbitrary division is done to organize thediscussion of the various services in a rational way. We defineInternet services as those services that are often offered to the worldat large or that are used to connect an organization to the worldwideInternet.
The services that are covered in this category are:
· Domain Name System (DNS) services
· sendmail
· Apache
· Login services such as FTP, Telnet, and SSH
· Routing protocols through Zebra and gated
· Network Address Translation (NAT)
Departmental services are those services that are usually limited to usage on the internal network.
The services that are covered under this category are:
· Dynamic Host Configuration Protocol (DHCP)
· Reverse Address Resolution Protocol (RARP)
· Network File System (NFS)
· Samba file and printer sharing
· LPR/LPD printer sharing
· Post Office Protocol (POP)
· Internet Message Access Protocol (IMAP)
· procmail mail filtering
In addition to these specific topics, this book contains generalinformation on configuring network interfaces, and important chapterson security and troubleshooting.
Linux Network Servers grew out of my earlier book, Linux NetworkServers 24seven. This new book, however, is more than a second edition.Although the character and content that drew high praise for theoriginal book remains, the new book has been completely reworked forthe professional system administrators who rely on the Craig Hunt LinuxLibrary. (Much of the praise for Linux Network Servers 24seven is stillavailable online for your perusal.) Introductory material from theoriginal book was removed to make room for more technical details inthis version. I believe, and I hope you agree, that this new book iseven better than its predecessor.
