Preface ^^^^^^^^^^^^^^ The programs and files in this distribution are FREEWARE. That is: they are copyright © Rudi Chiarito, but they may be freely distributed as long as no more than a nominal fee is charged to cover distribution costs. Moreover they can't be distributed separately or in a commercial package without written permission from the author. That's all. 1.2. Welcome to HiJack! ^^^^^^^^^^^^^^^^^^^^^^^^^ Do you have two or more computers and just one modem? Do you want to share an IP address among them? Well, then HiJack is a partial (still) 2.5kb large answer to your needs. /* *\ * 2 * Usage \* */ ^^^^^^^ 2.1. Requirements ^^^^^^^^^^^^^^^^^^^ HiJack hasn't been tested with AS225, but as far as I know it should work fine. If you manage to install and run successfully my 'beast' with the above-mentioned protocol stack, PLEASE contact me so that I'll be able to give users information about HiJack and AS225. 2.2. Installation ^^^^^^^^^^^^^^^^^^^ It shouldn't be that difficult, if you've already installed any other 3rd-party inetd daemons. You just basically need to bind as many ports as you want to HiJack by editing the AmiTCP:db/inetd.conf file on the computer which establishes the SLIP/PPP/WHATEVER connection and should work as some sort of gateway. Before doing that, you'll also have to add each of the ports to the AmiTCP:db/services database. Here are some (NON-WORKING!) examples... they must be appended to the files (lines with a leading # are just comments). Well.. of course the HiJack executable needs to be copied in AmiTCP:serv :) ------------------------------------------------------------------------------ AmiTCP:db/Inetd.conf ------------------------------------------------------------------------------ # Allows remote host to access my.host and foo.bar.com through telnet protocol HJteln stream tcp nowait root amitcp:Serv/hijack (HJ) my.host 23 HJfoo stream tcp nowait root amitcp:Serv/hijack (HJ) foo.bar.com 23 # Finger service on pippo.baudo.it PippoBaudo stream tcp nowait root amitcp:Serv/hijack (HJ) pippo.baudo.it 79 # an IRC server HJirc stream tcp nowait root amitcp:Serv/hijack (HJ) my.irc.server 6667 ------------------------------------------------------------------------------ AmiTCP:db/services ------------------------------------------------------------------------------ # Dont use already assigned port numbers! HJteln 2900/tcp HJfoo 2901/tcp PippoBaudo 2902/tcp HJirc 2903/tcp ------------------------------------------------------------------------------ 2.3. Getting started ^^^^^^^^^^^^^^^^^^^^^^ Provided that AmiTCP and inetd are running on the 'gateway', you should simply use your software from the other local hosts by accessing the ports you have configured. For example, by issuing on one of your computers the command telnet 2901 the login prompt of foo.bar.com should appear. PLEASE notice that not all of the services will work with the current release, ftp being probably the most notable. When using IRC, DCC GET/CHAT connections WON'T BE ESTABILISHED. The http protocol works just fine but it would be nearly impossible to follow links to other hosts since 1) you'd need to add such hosts to the configuration files 2) you'd also have to change the port numbers 'on the fly' A better 'trick' would be installing a http-proxy on your gateway. Such a solution provides a 'global cache' for all the local machines as well, shared also indipendently of the browser(s) used. /* *\ * 3 * Odds and ends \* */ ^^^^^^^^^^^^^^^ 3.1. HiJack: the making ^^^^^^^^^^^^^^^^^^^^^^^^^^ HiJack is a little C program, my third 'socket-based' program, compiled using SAS/C v6.56. Please dont blame me if it isnt 100% working! 3.2. Acknowledgements ^^^^^^^^^^^^^^^^^^^^^^^ I would like to thank... · Commodore-Amiga... · Luca Viola... my housemate, for testing HiJack using his A4000 (and also for porting ncurses, ytalk, ncftp 2.3.0 and midnight commander) · Sting, D. Fagen, Queen, D. Bowie, G. & P. Conte, Yes, Bangles, INXS, Elio e le storie tese, Dire Straits, Cure, D. Byrne, W.A. Mozart, B52's, Toto, L. Dalla, The Who, J.M. Jarre, Fleetwood Mac, L. van Beethoven... · D. Adams, M. Serra, K. Vonnegut, A. Rice, E. Queen, H. Hesse... · Michelle Their contribution has been invaluable to the development of this program! 3.3. Future improvements ^^^^^^^^^^^^^^^^^^^^^^^^^^ "If it's a future world we fear We have tomorrow's seeds right here For you can hold them in your hand Or let them fall into the sand" - Sting Here's what I'd like to add in future releases · An Installer script · Better documentation · Support for ftp etc · Who knows what else Any suggestions, as usual, would be very appreciated. Meanwhile *please* also check its stability and let me know about it... I've been testing HiJack a lot during the last weeks and it has never crashed on me (well, my housemate and I suspect that magplip.device should be responsible for the many reboots we have experienced lately). If you are almost 100% sure that you've found some bug, send me enough details to me and I'll try to track down the nasty creature. 3.4. The author ^^^^^^^^^^^^^^^^^ This program is FREEWARE. I don't ask anything, but if you like, you can send me PD programs, sources, money (why not?) or anything you can think of (I'd like to receive sweetmeats, anyway). Oh, yes, you can send me nice postcards, too. Here's my address... of course you can also send me suggestions, comments, questions, bug reports (Aaaaargh! God Forbid()!) and gossips! Email is far better: I study in Pisa (550kms from home) and most of the time I'm there. As if it weren't enough, mail delivery in Italy is sooooo sloooooooooooow...
