Uucpm software offers networked uucp services to older systems without such capability.
If you're using an older system like SCO Xenix or NCR Towers, you might find that you're lacking networked uucp services. That's where uucpm comes in. This software package provides TCP/IP networking support for systems that wouldn't otherwise have it.
The package includes two programs. The first is a port of the Berkeley `uucpd' daemon (version 5.9 6/1/90) to System V, usually run out of `inetd'. It authenticates incoming uucp requests and starts up a uucp session to talk to the remote system. The second program is a new program called `uucpm'. It's a daemon that converts a pseudo-tty (pty) into a device for network communications. The daemon sits on the master end of the pty, allowing `uucico' to connect to the slave end of the pty and issue requests to connect to systems across the network.
Once `uucpm' is installed, it's a simple one-line modification to the Systems and Devices files to implement TCP/IP capability. Here's a schematic diagram of how the pieces fit together:
+---------+ +---------+ +---------+
| uucico | -> | uucp | ->| uucp |
+---------+ +---------+ +---------+
| | | |/ /dev/ttyXX
+---------+ +---------+ +---------+
| pty | | uucpm | ->| inetd |
+---------+ +---------+ +---------+
| /dev/ptyXX | | socket |
+---------+
When `uucico' connects to the pty, the `uucpm' daemon issues a `host:' prompt. The originating system then sends the name of the remote machine. The `uucpm' daemon establishes a socket to the well-known uucp port on that system, and from there a standard uucp login is performed.
Overall, if you're in need of networked uucp services on an older system, uucpm is a great solution. The included daemons work seamlessly together to provide the necessary functionality, and installation is straightforward.
