KBtin

KBtin is a very heavily extended clone of well-known TinTin++.

If you're new to MUDding, I would really recommend using one of modern clients, such as Mudlet instead. The TinTin++ language is awful to use; the codebase in ancient; user-friendliness is an unthing.

On the other hand, it's one of last remaining text-mode clients, which enables you eg. to run it on a box in the same datacenter as the game server -- for juicy 0.1ms ping and thus reaction time -- while still giving you adequate interactivity despite you living on the other side of the world, hobbled by that pesky speed of light. You can use all the usual Unix tools like mosh, screen/tmux, etc...

The features include:

• editing keys, input box
• scrollback
• status line
• keybindings ("#bind F9 {do drop pasty from cloak,eat pasty}")
• aliases, actions (triggers), substitutions, highlights
• shortest-path graph traversing aliases ("mt>rh")
• guaranteed actions (a line being split between two packets is not a problem)
• lists processing ("#foreach {$friends} {tell $0 [XX] $message}")
• TELNET protocol support
• MCCP compression
• the ability to run local programs as it was a MUD -- this is the only client you can use with games like adventure, or even programs like mysqlclient
• secondary sessions (ICQ integration, etc)
• UTF-8 and IPv6 support
• native SSL, with certificate retention to avoid MitM attacks
• fractional arithmetic

KBtin has been ported to the following systems:

• Linux
• SunOS^{long untested}
• MacOS X
• {Free,Open,Net}BSD
• Tru64 Unix^{long untested}
• HP-UX^{long untested}
• IRIX^{long untested}
• SCO OpenServer^{long untested}
• Solaris^{long untested}

Dependencies required to build:

• cmake
• perl
• zlib (libz-dev) [OPTIONAL]
• gnutls (libgnutls28-dev) [OPTIONAL]
• hyperscan/vectorscan [OPTIONAL]
• valgrind-dev [OPTIONAL]

Security warning

This codebase is truly ancient, and large pieces of it have been written by people who were obviously 1st year students with only a beginner's knowledge of C -- at a time when even good programmers' practices could be considered atrocious by modern standards. While any obvious holes have been patched by yours truly, it's beyond any doubt that further security issues may be found by anyone who bothers to look closely enough. Thus:

DO NOT EVER CONNECT TO A REMOTE SERVER WHOSE ADMINS YOU DO NOT TRUST.

Then why even bother with KBtin? Well, a sizeable minority of players still swear by clients like CMUD or zMUD that haven't been updated since beginning of this millenium, and sky isn't falling.

Still, you should not use KBtin (nor play most remote-accessing games) from any account/machine you have sensitive data -- including credentials -- on.
