Writing an FTPD in DGD

An FTPD can be an excellent alternative to providing your MUD coders with telnet access to your server (which can be insecure). You can either run an external FTPD which is restricted (via chroot()) to a particular subset of your filesystem and has its own restricted user list, or you can build an FTPD into your MUD and handle the security problems there.

Since standard DGD doesn't allow outgoing network connections, and standard FTP protocol requires them, you can't write an active FTP server in unpatched DGD. You choices are to apply the network patch to DGD or to write a passive-mode-only FTPD.

There are existing FTPD implementations in LPC, but none specifically for DGD. Still, you can adapt the FTPD from, say, TMI-2 to run under DGD, either with the network patch or by removing all code that would require outgoing connections.
