Created in the early 1970s, Telnet provides a method of running command
|
|
line applications on a remote computer as if that person were actually at
|
|
the remote site. Telnet is one of the most powerful tools for Unix, allowing
|
|
for true remote administration. It is also an interesting program from the
|
|
point of view of users, because it allows remote access to all their files
|
|
and programs from anywhere in the Internet. Combined with an X server (as
|
|
well as some rather arcane manipluation of authentication 'cookies' and
|
|
'DISPLAY' environment variables), there is no difference (apart from the
|
|
delay) between being at the console or on the other side of the planet.
|
|
However, since the 'telnet' protocol sends data 'en-clair' and there are
|
|
now more efficient protocols with features such as built-in
|
|
compression and 'tunneling' which allows for greater ease of usage of graphical
|
|
applications across the network as well as more secure connections it is an
|
|
effectively a dead protocol. Like the 'r' (such as rlogin and rsh) related
|
|
protocols it is still used though, within internal networks for the reasons
|
|
of ease of installation and use as well as backwards compatibility and also
|
|
as a means by which to configure networking devices such as routers
|
|
and firewalls.
