The information below, to the
best of my knowledge, is an accurate guide to connecting to talkers via
telnet. If you have any additional advice or corrections please email me
at alexis@li.net.
UNIX
Mac
Windows
Firewalls
UNIX
The basic telnet provided
on UNIX works fine, if a little inelegantly. You may have firewall concerns
(see below). If you prefer, a MUD client such as TinyFugue
(aka tf) will work as well. To connect to a talker from UNIX simply type:
telnet host port at the prompt, like so:
korova:/home/alexis 75 % telnet mudhole.ehche.ac.uk 4444
Macintosh
The standard
NCSA telnet works wonderfully on Macintosh. Simply download it to your
Desktop and double click to install it. It's distributed as a BinHexed
StuffIt archive. After installing it, go to the `Open Connection' dialog
box (Command-O) and type the address you wish to connect to in the `Host'
space, making sure to include the port number if one is specified.
Windows 3.1 / 95
Most Windows telnets are utterly
crap, and present a major problem for some sites: these apps operate only
in character mode, making it impossible for the user to talk on sites
that only allow line-mode (the default for UNIX telnet) COLD in
particular. If you find that every time you type a character, the talker
behaves as if you've hit enter (you can only type one letter at a time)
you're in character mode when you should be in line mode.
I've found 2 solutions to
this problem:
a. Use a MUD client.
The best MUD client, Zmud,
presents a problem in that most of the punctuation characters are
reserved as commands. Talkers, which expect many of the same characters,
don't work very well with it. The tried-and-true MUD client is WinWorlds,
which I have attached to this page, version 0.1a. To install
it:
1. Download both wwrld02.zip and vbrun300.zip by clicking on the links in
Netscape. The first file is the program; the second is a Visual Basic
library that is missing on some PCs.
2. Unzip both files using a
program such as WinZip.
3. Move the vbrun300.dll file
(from vbrun300.zip) and the .vbx files from wwrld02.zip into your
\windows\system directory.
4. Move the other files from
wwrld02.zip into the directory of your choice.
b. Use NetTerm.
NetTerm is a standard, very
full featured telnet program available via shareware. It is available
from papa.indstate.edu and its
mirrors.
Nnt16420.exe
is for 16 bit (Win3.1) and
nt32420i.exe
is the 32 bit (Win95 and NT) version. It's distributed as a
self-extracting executable file; simply run the program to install
it.
The only problem I've
experienced with NetTerm is that, at least on the Windows 3.1 system I
used it on, it did not correctly display non-ASCII characters. Instead
of, say, an é (e with an accent) I would get a symbol character.
My guess as to why is because the PC and UNIX character sets are
different, but I'm no expert.
Firewalls
A firewall is an electronic
barrier between your site and the rest of the Internet. They vary in
level of restrictiveness, but what they all have in common is a desire to
restrict, in some way, connections between your site and those `beyond
the firewall'. This can present problems when one is trying to use
talkers, as alternate port numbers may be blocked, or you can't telnet
directly at all.
Firewalls are most commonly used
at corporations and universities; private providers don't tend to
restrict the sites available to their users. The simple (but not
infallible) test to see if you're firewalled is to go to the Network
Preferences dialog in Netscape and look under `proxies'. If you're
configured to use a proxy server you're probably firewalled. Try turning
proxies off, then going to the Netscape home page (or any page not within
your domain). If it works, then your proxy is only a cache server, which
is basically a sophisticated, big version of the Netscape cache. If it
doesn't work, you're firewalled, at least for HTTP connections; contact
your systems administrator for details. Remember, though, if your boss
thinks you're playing on company time, you may not be employed for long!
