TELNET

(Note from the Author: Check back again soon, for the suggestions for the Topic wise sites to telnet to )

Telnet is a service on the Internet which allows you to log on to a remote system, provided you have the userid and password. There are however computers around the world which permit guest logins, including VSNL's host computer, for the Terminal account. In case you have an account on some remote computer, e.g. arbornet or cyberspace.org, which provides services that are not provided by VSNL (till the time of this writing), then, in order for you to use those services, you have to learn to use guest login.

Like any large community, cyberspace has its libraries, places you can go to look up information or take out a good book. Telnet is one of your keys to these libraries.

Telnet is a program that lets you use the power of the Internet to connect you to databases, library catalogs, and other information resources around the world. Want to see what the weather's like in Vermont? Check on crop conditions in Azerbeijan? Get more information about somebody whose name you've seen online? Telnet lets you do this, and more. Increasingly, information once available only via telnet is being disseminated by the World-Wide Web-- see Chapter 7-- but it can still be useful to learn your way around telnet.

To start using telnet, select item 3 from the First Menu, and you will get a telnet prompt as shown

in Fig.6-1:

SunOS UNIX (svpal)

login:


At telnet prompt type "open telnet-site-name". In this case we typed "svpal.org" , a computer in California. The telnet utility logs on to that site and informs you that the computer you have been connected is running Sun's Operating System UNIX and gives you a login prompt. In this case, this not being a free site, you have to have an account there to log on, like what you require to log on to VSNL's GIAS. If you supply a valid userid and password you will be in the account and your computer terminal will act as a terminal to that account.

This is all there is to telnet. Of course there are advanced features to telnet, but unless you are going to use this service extensively and for more than logging on to a computer, you have no need to bother about it.

Below we list all the other options available with this service:

close close current connection.
display display operating parameters.
mode try to enter line-by-line or character-at-a-time mode.
open connect to a site. This can be abbreviated to "o".
quit exit telnet.
send transmit special characters ('send ?' for more)
status print status information.
toggle toggle operating parameters ('toggle ?' for more)
z suspend telnet.
? print help information.
set set operating parameters ('escape char ^C' to get out of
telnet. This sometimes is very important. E.G. if you are
using Procomm Plus for DOS, the standard escape
character is "^]". But for Procomm this keyboard
sequence will toggle the bottom status bar and from your
computer you won't be able to send this character
sequence to get out of the telnet session. You can set
escape character to "^C".

The commands given above are some of the most frequently used ones, but there are many more and also there are sub-commands. Try the command "set ?" to see the list of these offered by your operating system.

There are lots of sites around the world which allow you to log on without a password. They can be searched on the NET.
