McFeely requires libknetstring. Source and binary RPMs as well as a tarball are also in the distribution directory . IO 1.20 works and is available from CPAN . It may be run out of inetd, but if you prefer it works well with tcpserver. You can get tcpserver as part of the ucspi-tcp package.
RPMs are available .
At Kiva Networking , where McFeely was first put together, the communication between the mcfeely server and remote mcfeely clients is done through ssh tunnels. This is not required, but is probably a good idea if you are going to be using mcfeely on an open network. If you have questions on how to do this, please subscribe to the mailing list and ask, that will help us to create good documents. Here are some preliminary documents that describe McFeely. Obviously more is needed.
