Free cmc software for linux

naim project is the original ncurses, console-based AIM client, which also supports IRC, ICQ, and Lily CMC.
For AIM and ICQ, it uses the TOC protocol, and includes many commonly-requested features found nowhere else, while still preserving naims classic look and feel.
Main features:
- naim includes unique features like zero-configuration peer to peer encryption, automatic message queueing, and incoming message modification (to correct common spelling mistakes and expand common abbreviations; see /help filter).
- naim also includes powerful dynamic module support, allowing developers to modify all major aspects of naims behavior.
- Third-party plug-ins have been used to extend naims functionality for use in embedded monitoring clients, and for use as host to automatic clients ("bots").
- The naim-modules package (distributed below) includes several example plug-ins, including a telnet server (nsocket), an interactive bot (naimusers), and a simple anti-spam measure (nantispam).
- When combined with GNU Screen, naim is great to use as a chat client as well as an answering machine. Individual users can detach, log out, pack up and go home, then log back in from anywhere on the Internet to resume their naim session.
- naim is maintained by an OPEN, DIRECTED COMMUNITY, and has been in development since October, 1998.
