<p><strong>Greetings,
|
||
|
</strong></p>
|
||
|
<p><strong>I used to be a sysop of FidoNet using Maximus as my BBS system in
|
||
|
DESQview environment. Now I have switched from DOS/Windows to Linux
|
||
|
as my major working platform.
|
||
|
</strong></p>
|
||
|
<p><strong>The question is, is there any BBS system that is recommended to run
|
||
|
in Unix ? It should be able to handle both dial-up & TCP/IP, of
|
||
|
course. <IMG SRC="../gx/dennis/smily.gif" ALT=":)" height="24" width="20" align="middle">
|
||

|
||
|
|
||
|
<blockquote>There are several packages there --- including a number of
|
||
|
utilities for ifmail (the Internet to FIDO gateway).
|
||
|
</blockquote>
|
||
|
<blockquote>Most of these are free or shareware.
|
||
|
</blockquote>
|
||
|
<blockquote>There are also Linux ports of MajorBBS and MMB Teammate
|
||
|
(a couple of major commercial BBS packages --- which are
|
||
|
pretty expensive).
|
||
|
</blockquote>
|
||
|
<blockquote>I haven't used any of them so I can't offer specific
|
||
|
suggestions. However, I've crossposted the two newsgroups
|
||
|
that are most likely to have interested and informed
|
||
|
participants (alt.bbs.unixbbs and comp.bbs.misc).
|
||
|
</blockquote>
|
||
|
<blockquote>There are about 50 newsgroups devoted to BBS'
|
||
|
(including various specific BBS packages like TBBS,
|
||
|
MajorBBS, Citadel, etc).
|
||
|
</blockquote>
|
||
|
<blockquote>(I've been a sysop on two large corporate systems,
|
||
|
for Symantec and for McAfee --- so, I used to subscribe
|
||
|
to some of these. However I've never run a small hobbyist
|
||
|
system so I just haven't kept up in the field).
|
||
|

<blockquote>Linux can handle dial-up as well as console login and give a remote user
|
||
|
normal shell. But you probably want to restrict access for BBS users.
|
||
|
</blockquote>
|
||
|
<blockquote>You can set them up with simple shell script (or <tt>perl</tt>,
|
||
|
or <tt>tcl</tt>) which
|
||
|
would emulate maximus as close as you wish, but I think that better
|
||
|
approach is to use text-based web-browser
|
||
|
<tt><a href="http://lynx.browser.org/">lynx</a></tt> for their shell.
|
||
|
</blockquote>
|
||
|
<blockquote>These are likely to be severe security problems unless
|
||
|
you are a phenomenally good (and careful) programmer.
|
||
|
</blockquote>
|
||
|
<blockquote>I'd did play with a configuration that ran <tt>lynx</tt> in a
|
||
|
chroot jail. That was to prototype a "dial in kiosk"
|
||
|
</blockquote>
|
||
|
<blockquote>One sticking point for my application was that I wanted
|
||
|
a replacement '<tt>getty</tt>' that could auto-detect ANSI PC
|
||
|
emulation (which many BBS' can do with some sort of
|
||
|
magic escape code) and bypass the Unix login command
|
||
|
--- I think I replaced /bin/login in the jail with an
|
||
|
SUID "nobody" copy of <tt>lynx</tt>, and put a <chroot><tt>/etc/issue</tt>
|
||
|
that just said: "Hit any key to ...."
|
||
|
</blockquote>
|
||
|
<blockquote>Thus you set up normal Web site instead of BBS, solving problem with
|
||
|
TCP/IP instantly, and let dial-in users to view it in <tt>lynx</tt>.
|
||
|
<tt>Lynx</tt>
|
||
|
includes provisions to download/upload files using Z-Modem and Xmodem
|
||
|
(by calling external programs <tt>sz</tt> and <tt>rz</tt>) and allows to
|
||
|
restrict users almost as much as you wish.
|
||
|
</blockquote>
|
||
|
<blockquote>However, those various restrictions may not be foolproof.
|
||
|
There have been exploits that bypassed <tt>lynx</tt> restrictions before.
|
||
|
</blockquote>
|
||
|
<blockquote>So, if security is an issue, you definetely want to
|
||
|
lock this in a jail with no shell and take some other
|
||
|
precautions.
|
||
|
</blockquote>
|
||
|
<blockquote>You are right that this is an interesting way to
|
||
|
provide "kiosk" style dial-up using stock HTML/web pages
|
||
|
and off the 'net freeware. That was the whole point of
|
||
|
my prototype (which took all of about three hours one
|
||
|
afternoon).
