- INTRODUCTION
- ------------
- What is AmiTrack? Hmm, good question.
-
- I was talking to an AmiPhone user a few weeks ago, and
- he was lamenting that it was hard to find another AmiPhone
- user who was online to talk to. We decided what was needed
- was a way to find out who else is available, sort of an
- "Active Amiga registry".
-
- So that's what AmiTrack does. AmiTrack is an AmiTCP program
- that acts as the keeper of a list of Amigas that are currently
- on-line. It isn't limited to just AmiPhone users, either; you
- can register your Amiga to advertise any message string you want.
-
- This archive contains two executables: AmiTrack and AmiTrackServer.
- AmiTrack is a client that you can use to notify the world of your
- Amiga's presence on the internet, and AmiTrackServer is useful if
- you wish to let people use your Amiga as a registry site. Both
- utilities must be launched from the CLI.
-
-
- INSTALLATION
- ------------
- There isn't any, really. Just copy the files to wherever you
- want to keep them.
-
-
- AMITRACK
- --------
- The AmiTrack program is designed to connect to an Amiga running
- the AmiTrackServer program. While connected, it periodically
- does two things: it sends "ping" packets to the AmiTrackServer
- to let it know that you're still there, and it downloads the
- list of currently registered Amigas on that server, for your
- viewing pleasure. When you quit AmiTrack, you will be removed
- from the server's list of Amigas.
-
- AmiTrack understands the following command line arguments:
-
- #1: The Internet host name of the Amiga that is running AmiTrackServer,
- that you wish to register with.
-
- #2: The comment string you wish to have associated with your Amiga.
- Make sure to put this string in "quotes" if there are any spaces
- in it. This defaults to no comment.
-
- #3: The port number on the server which you wish to connect to.
- This defaults to port 18945 (which by some bizarre coincidence,
- is also the default port for AmiTrackServer to accept connections
- on)
-
- So, a valid AmiTrack command could be:
-
- AmiTrack
-
- or,
-
- AmiTrack isys.ml.org "This is my comment" 5217
-
- or anything in between.
-
-
- AMITRACK GUI
- ------------
- AmiTrack's GUI is fairly straightforward. It consists of several
- string gadgets, two buttons, and a ListView. The Server, Port, and
- Comment string gadgets are self-explanatory (I hope!). The ListView
- shows the IP addresses and comment strings of everyone logged in
- to the server you are connected to. This list may be updated by
- clicking on the "Refresh" button, and will also be updated automatically
- every few minutes, as indicated by the associated string gadget.
- The "Ping" button causes your client to send a packet to the
- AmiTrackServer, in effect saying "I'm here!". If the AmiTrackServer
- does not hear from your client for about five minutes straight, it
- will assume that you are no longer available and remove you from
- its list. Hence, it is probably a bad idea AmiTrack's ping interval
- to more than five minutes.
-
- Automatic refreshes and pings can be disabled by setting their
- interval gadget to zero.
-
- AmiTrack can be iconified via the Project menu. Double clicking
- on its icon will bring back its GUI. It will continue to ping
- the AmiTrackServer while it is iconified.
-
-
- AMITRACKSERVER
- --------------
- The AmiTrackServer executable is designed to accept AmiTrack
- client connections from all over the Internet and dole out
- information about who else has connected to it recently. Most
- people won't need this program, but it's there anyway for those
- who would like to run their own server. AmiTrackServer has no
- GUI, rather it sends only output to the CLI. It will display
- its list of registered Amigas to the CLI at regular intervals,
- and whenever the list is modified. The list displays the IP
- name of each Amiga, its comment string, and the number of seconds
- that have elapsed since the last "ping" was heard from that
- Amiga.
-
- AmiTrackServer takes one optional command line argument, the
- port number upon which it is to accept connections. This number
- defaults to 18945.
-
- AmiTrackServer will quit if sent a CTRL-C signal, and will
- refresh its CLI output of its list if send a CTRL-D.
-
-
- TECHNICAL
- ---------
- AmiTrack tries to be as reliable and efficient as possible.
- The AmiTrack server keeps a linked list of the currently
- registered Amiga hostnames and their comment strings, as
- well as a timestamp of last time those Amigas were heard from.
- If an AmiTrack client has not sent a packet to the server
- for a specified amount of time (currently five minutes),
- it is liable to be removed from the registered list. This
- way, even if the client crashed and didn't send a disconnect
- packet, its entry won't hang around forever. To retrieve
- the list of clients, AmiTrack opens a TCP connection to
- the AmiTrack server, which immediately spits out a list of
- IP numbers, names, and comment strings, and then closes the
- connection.
-
- AmiTrack is written in DICE C, but there shouldn't be anything
- too compiler-dependant in it.

- ------
- This program was written by Jeremy Friesner, using DICE C.

-
- ACKNOWLEDGEMENTS
- ----------------
- Thanks to Oliver Hotz for providing a full-time AmiTrack server site.
- Thanks to AndyS and Gallant on #amiga for helping me debug & test.
-
-
- DISTRIBUTION
- ------------
- AmiTrack is fully in the public domain. Do whatever you want with it.
-
-
- BUGS
- ----
- - Comments with leading spaces can mess up the client's field alignment.
-
- - Sometimes after you exit the server, it can't be run again
- for a minute or so afterwards (it will error out, saying the
- TCP port is in use). This usually happens if GetTrackList has
- been run on this server recently. I think this is a "feature"
- of BSD-based TCP software, though, as I've seen the same
- thing happen on UNIX machines running other software.
-
- - There ought to be a mechanism to ensure that you can't set the
- ping interval to be greater than the server's timeout interval.
-
-
- TODO
- ----
- - Make a UNIX version of the server, and perhaps the client
- as well.
-
- - Add a way to automatically launch your favorite net program
- with a given hostname from the list as an argument.
-
- - Add a "NO GUI" option for completely invisible background use.
-
- - Make AmiTrack runnable from the Workbench.
-
-
- OTHER STUFF
- -----------
- Some other programs I wrote: (try them, they're cool! ;))
-
- GadMget - Loads in an Aminet RECENT or INDEX file and lets you choose
- files to download via a pair of ListViews. Features keyword
- searching and sorting by name, size, age, directory, and
- description. When you're done, it outputs the ftp commands
- that are needed to download the selected files. The output
- formatting is extremely flexible, allowing generation of
- many formats: ftp, ncftp, ftp-by-mail, shell scripts, etc.
- Comes with an ARexx script to completely automate downloading
- with ncFTP. (util/misc/GadMget2.05.lha,93K)
-
- AmiSlate - A paint program that works with AmiTCP to allow two people
- to cooperatively paint on the same drawing from different
- computers. Features an extensive ARexx port which allows
- the construction of new features and games. Comes with
- ARexx scripts for chess, tic-tac-toe, backgammon, and others.
- (comm/tcp/AmiSlate1.4.lha,115K)
-
- AmiPhone - An Internet voice-chat program, similar to IPhone and
- VoiceChat and Nevot and all that, only Amiga-specific.
- Features aflexible buffering mechanism for slow connections,
- an ARexx port, IFF 8SVX transmission and playback, internal
- multitasking, and support for a variety of digitizers.

- HISTORY
- -------
- 1.1 : (Public Release 6/28/96)
- - Separated the AmiTrack server and client into two separate
- programs, and integrated GetTrackList into the client.
- - Added a nice GUI to the client program.
- - The AmiTrack protocol has changed slightly--v1.1 is not quite
- compatible with v1.0. Sorry! :(
-
- 1.0 : (Public Release 6/7/96)
- - Initial release. Works well for me, but untested in "real life".
