Summary
Linux and networking go hand in hand. The Linux kernel has
support for all common and most uncommon network protocols. The
standard UNIX networking tools are provided in each distribution.
Next to those, most distributions offer tools for easy network
installation and management.
Linux is well known as a stable platform for running various
Internet services, the amount of Internet software is endless. Like
UNIX, Linux can be just as well used and administered from a remote
location, using one of several solutions for remote execution of
programs.
We briefly touched the subject of security. Linux is an ideal
firewall system, light and cheap, but can be used in several other
network functions such as routers and proxy servers.
Increasing network security is mainly done by applying frequent
updates and common sense.
