Cross-platform, Easy-to-Use Local LAN Chat?

Cliff posted more than 10 years ago | from the simple-communication dept.

Communications 39

Ars-Gonzo asks: "I was at a conference last week, and had a surprising number of people connected to a peer-to-peer wireless LAN during the lectures. I saw several Mac users typing away during the lectures, and I found out later that they were using iChat's Rendezvous-based local chat to talk to each other. iChat's local subnet chatting functionality is supposedly based on Jabber, but I can't get a Jabber client (on Windows or Linux) to connect to iChat, locally. Has anyone seen any iChat compatible LAN-chat apps for a platform other than Mac?"

GNAA Announces responsibility for kernel backdoor (-1, Offtopic)

GNAA Announces responsibility for kernel backdoor
By Tim Copperfield
Raleigh, NC - GNAA (Gay Nigger Association of America) this afternoon announced one of their loyal members was responsible for planting the "backdoor" inside the popular opensores operating system, Lunix [] (Stocks [] , Websites [] ).

In a shocking announcement this afternoon, GNAA representative goat-see revealed that the mistery hacker who penetrated high-security defenses of the Lunix "source code" repository and injected viral gay nigger seed deep inside the kernel was indeed a full-time GNAA member.
"This is serious," goat-see began. This is a first event of such magnitude since GNAA opened its doors to new members in 1996. Until now, we were gathering new members by announcing our group information on a popular troll website, [] , but this is a whole new era. By injecting our holy gay nigger seed right into the Lunix kernel, we will be able to immediately collect thousands of members. "Make the most of the next six weeks," he added. "We will grow in numbers more than you can possibly imagine".
Insertion of the GNAA backdoor came right between the consideration of Novell [] to buy out the entire Lunix Kernel programming team, and will most likely positively affect the decision. By adding all the gay niggers working for Novell with the gay niggers developing Lunix kernel source, GNAA will be all-powerful and will begin plotting our next plans to add "backdoors" into the next favorite operating system, BeOS [] .

About Lunix
Lunix is an operating system. An operating system is the basic set of programs and utilities that make your computer run. Some other common operating systems are Unix (and its variants BSD, AIX, Solaris, HPUX, and others); DOS; Microsoft Windows; Amiga; and Mac OS.
Lunix is Free Software. Now, just because it's Free, doesn't necessarily mean it's free. Think "free" as in "free speech," not "free beer," as we in the Free Software/Open Source community like to say. In a nutshell, software that is free as in speech, like Lunix, is distributed along with its source code so that anyone who receives it is free to make changes and redistribute it. So, not only is it ok to make copies of Lunix and give them to your friends, it's also fine to tweak a few lines of the source code while you're at it -- as long as you also freely provide your modified source code to everyone else. To learn more about free software and the major software license it is distributed under, called the General Public License (GPL), go here [] .

Windows Messenger and/or Net Send (1, Funny)

Nomihn0 (739701) | more than 10 years ago | (#8710105)

What about the built in Windows Messenger service? All you have to do is hand out a list of computer names and you're good to go.

if that is not your style, then write a frontend for Net Send using VB and just "net send ' Response with your computer name" That's worked wonders for me on school networks in the past.

Re:Windows Messenger and/or Net Send (2, Funny)

gazoombo (650701) | more than 10 years ago | (#8710879)

Re:Windows Messenger and/or Net Send (1)

fyonn (115426) | more than 10 years ago | (#8718020)

when I was at university (UND in south africa) one of the lab tech's used a net send (or novell's equiv, it was a while ago) to send a message to everyone in the lan about a broken printer I think. As I vaguely knew the lan admin I replied and we spent the next hour chatting via net sends.

at that point I was using 3 computers at once. one with windows 3.11 loaded and netscape 2 running from disk, one in dos running several ncsa telnet sessions to the CS student unix box (beastie for anyone who remembers) and a third machine just running net sends.

actually, that lan admin was incredibly cute.. *sigh* happy days...


Re:Windows Messenger and/or Net Send (1)

afidel (530433) | more than 10 years ago | (#8710936)

Not even necessary in a domain environment, the network will find a user name and send the message to them. Not sure exactly how it handles multiple logins but I've never failed to contact someone I knew was online.

Dude, that's exactly what I did back in Grade 8.

VB program for messaging around the school network? I was -selling- this program! Had some registration key thingy for it, sold the keys for 50c each, and they are locked per user, so they can't share keys.

It was all good until I was experimenting with net send one day, and accidently sent it to the domain. Simultaneously, every computer on the school network went "ping!". I logged off and slowly walked out of the computer room...

Needless to say, it got banned. And I wasn't punished or anything.... woohoo!

You'll have to create a text file with a list of everything you want to send to, though.

Probably not Jabber-based (4, Informative)

mrpuffypants (444598) | more than 10 years ago | (#8710108)

I'm going to argue that iChat's LAN chatting mechanism probably isn't based upon Jabber at all. Jabber is a server that clients all connect to, whereas Rendezvous is a true P2P technology, where everybody connects to everybody else.

And good luck on getting 3rd-party support for other protocols in iChat. Apple's got that bolted down to AIM and Local LAN chatting.

Re:Probably not Jabber-based (1)

2nd Post! (213333) | more than 10 years ago | (#8710320)

If nothing else, the discovery mechanism is Rendezvous, so if you've got an open source AIM client that's willing to implement Rendezvous discovery, I bet it would be simple enough to 'sniff' the LAN and figure out how to chat with the iChat clients.

No harder than figuring out any other chat protocol.

Message format (1)

lovelace (4159) | more than 10 years ago | (#8711265)

The message format is exactly Jabber (just load up ethereal if you don't believe me), but the discovery mechanism is based on Rendezvous. The conversations themselves happen peer to peer (the ones I've seen are on port 5298, but since the port is specified through multicast dns that could probably be anything). Creating a client for linux would be easy, but the most difficult part would be setting up the multicast DNS. Mandrake 10.0 ships with a multicast DNS responder but afaik no other linux distros do.

Re:Probably not Jabber-based (1)

jahndm (213097) | more than 10 years ago | (#8711589)

iChat Rendezvous uses ports 5297 and 5298. Or at least those are the ports that are opened up if you enable iChat Rendezvous in Mac OS X's firewall setup.

winpopup (1)

winpopup []

Re:winpopup (1)

bhtooefr (649901) | more than 10 years ago | (#8714327)

It works totally differently on NT/2000/XP/2003. Fire up a command line, and type "net send ", then the computer or user name you wish to send to (and a space), then the message you wish to send. You do not need WinPopup running on the client if it is one of the OSes mentioned above, but Windows Messenger Service must be enabled (it is by default, but it is often disabled for security reasons).

irc, of course (2, Informative)

jleq (766550) | more than 10 years ago | (#8710170)

just set up an irc server, give out the IP address, and let the conversations begin! i've had some good experiences with bircd (, it's quite lightweight, and works well

Re:irc, of course (2, Informative)

cgranade (702534) | more than 10 years ago | (#8710240)

I agree. IRC may not be fully P2P, but it is very reliable and complete. There's a client for every known OS, and its name is X-Chat [] . Only one big problem: seizure of the server can reveal who connected, which isn't good for sharing files. For chatting, though... it works wonders.

iTunes chat (5, Funny)

Dixie_Flatline (5077) | more than 10 years ago | (#8710401)

My sister got involved in this one day while she was sitting around in an office at her university.

She and her friend were both working on their laptops, and they both had iTunes opened. They were sharing their playlists, and came across a playlist with some good music (belonging to someone that I'll name GuybrushT). Clever person that she is, she changed the name of HER playlist to say 'GuybrushT is cool!'. He noticed, and she and her friend and GuybrushT had a conversation, all in their shared playlist names!

Your other alternative is, of course, to buy yourself an iBook and just give in to Apple and OS X. It's a pretty cheap way to buy an addition to your social life.

Searched - Eimp (2, Informative)

Cyberop5 (520141) | more than 10 years ago | (#8710616)

I searched the web for about an hour and I wasn't able to find much. The UPNP vulnerabilities in Windows XP seemed to have scared many people away.

I was able to find this [] , but rendezvous support isn't fully integrated. The feature status is at 50% now and the developer hasn't posted anything in 4 months. There are rendezvous libraries in the latest release.

I'm in the process of trying out Eimp. Its not a very robust program, but it does seem to offer rendezvous support. I'm testing it now, I'll reply with results.

There is also JXTA - a jabber/rendezvous/zeroconf chat protocal being developed by sun.

Re:Searched - Eimp (3, Informative)

Cyberop5 (520141) | more than 10 years ago | (#8710858)

it only seems to support Rendezvous discovery. I can see my other system online, but I cannot chat with it. This is very buggy software. I can't remove persons on my contact list either, even if i create them. I can however, see their status. IOW, Eimp has a ways to go.

It's somewhat open (3, Insightful)

eyeball (17206) | more than 10 years ago | (#8710836)

I'm no expert in rendezvous, but it uses open (although not too commonly used) protocols like multicast-DSN. See Apples FAQ on Rendezvous []

As for iChat LAN (which I'm pretty sure is much different than AOL's protocol). Looks like these guys reverse engineered and built a LAN iChat plugin [] for Proteus (the multiprotocol IM client). They have the source available for download.

It would be possible to port the rendezvous+iChat protocol to a Jabber server plugin.

Re:It's somewhat open (1)

burns210 (572621) | more than 10 years ago | (#8711845)

Rendezvous is Apple's implementation of the open standard of zeroconf... Linux could just as easily have a compatable equivalent if someone coded it. Apple employees the main(or one of the main) developers/writers/originators of the standard, which is why they have adopted and used this super-awesome protocol so quickly.

iChat does borrow from Jabber... (2, Informative)

Wade Tregaskis (696280) | more than 10 years ago | (#8711285)

...but nothing useful for your purposes, in this case. The local messaging uses a subset of the Jabber protocol (as opposed to the AIM protocol used for peer->server->peer messaging). I think the file transfer code is also based in part on Jabber, although I do know that some of the essential specifics are proprietary and undocumented (the original developer made the note a few weeks ago that he can't even remember how it works anymore).

So while it does borrow from Jabber, it doesn't "use" Jabber. You can't connect to a Jabber server, nor communicate directly between Jabber & iChat.

There are some chat clients out there with similar functionality on Windows (and I believe Linux), but they're somewhat hit-and-miss affairs, from my experience. I like the suggestion to just get an iBook - I already have one :) - but a more reasonable idea is probably to look at Proteus, as someone mentioned, and think about some sort of Windows/Linux/your-poison port.

Xuri (755951) | more than 10 years ago | (#8714447)

Not iChat related, nor cross-platform, but... On my neighbourhood-LAN(includes coax, tp & wireless heh..) we use Cheezepopper [] . It's not fancy, it's not filled with dozens of cool features - but it does list all computers on the LAN and allow you to send messages either directly to said computers or to the domain/workgroup they're on.

A potentially hazardous (to your own health) program for big LAN-parties where lots of people have neglected to turn off their Messenger-service in Windows before booting up Counter-Strike for the compo-finals, but generally a decent program which behaves most of the time, and a great replacement for Windows' built-in messenger service in any case. ;P
