iBBS follows a clever concept by utilizing standard UN*X / Linux tools like inn, alpine, talk etc. in order to provide a compact yet feature rich BBS system. This allows for a high level of customization as additional programs (e.g. ntalk) can easily be added to the corresponding menu (bash) script. iBBS also offers file areas and classic X/Y/Z modem uploads through the default command line tools provided by lrzsz (another clever way of implementing such a feature). However, installation instructions are a bit vague when it comes to configuring xinetd, telnet, inn (NNTP server) which are used as the core technologies behind the iBBS shell script collection. What I like about iBBS is that due to the way it is implemented, your BBS has a more unixish look and feel to it.
