Remote connections.

	Rlogin and telnet are two programs which allow you to log into
remote systems elsewhere on the internet.  You typically need to have
an account on the machine you're connecting to, however many services
on the internet are available via remote connections with special
names and passwords.

	To telnet to a remote system, you need to enter the entire
internet address of the remote system (the address of this system is
"earth.execpc.com", if you'd like to telnet here from somewhere else
on the internet).  You may also enter in an optional port number.
Some machines offer special services, for which you have to use a
special port number.  For example, "lambda.parc.xerox.com 8888" would
connect you to the popular LambdaMOO game.  "madlab.sprl.umich.edu
3000" would connect you with a machine dedicated to offering weather
data.  If you're outside the menu, you can always type "telnet",
followed by the machine name and the optional number.

	When you telnet someplace, you will be offered a login prompt
on the remote machine, and you can then log in as if you had dialed
there.  There are no long-distance charges on the internet, but it is
considered polite to not do non-essential telnetting during business
hours (if you're telnetting somewhere far away, remember time zones!).
Besides, telnetting during off hours means a much nicer connection
with less lags.  When you log off of the remote system, you'll be
right back here again.

	In telnet, the fastest way to end a connection is to press
control-], and then at the "telnet>" prompt, type "close".  You can
press "?" at the telnet> prompt for a list of settings you can change,
but this is almost never necessary.

	Rlogin is telnet's older brother.  You can only log in with
rlogin, not use port numbers.  Rlogin offers no advantage over telnet,
but in rare cases, it can offer a better connection.  To escape out of
a rlogin session, either log off the remote host, or hit the return
key, the tilde (~), then a period.
