Network
When x29uucpd is executed, it examines the /etc/x25/x29hosts file for all PAD devices that are configured for UUCP.
When x29uucpd receives a copy request, it establishes an SVC with the remote host specified by the X.121 address and transfers the data.
If the remote host is an HP 9000, the x29server process monitors that system for incoming calls. x29server and x29uucpd cooperate to handle all SVC requirements while the UUCP processes on each system perform the UUCP operations.
When the UUCP data transfer is complete, the UUCP processes terminate. x29server and x29uucpd then terminate the SVC connection.
Configuring UUCP PAD Support
To configure PAD support for UUCP services, the x29hosts file and other system and device files must contain the appropriate references and parameters. This section provides information on configuring these files. See Appendix B, X.25 Configuration Files and Examples, for examples of the x29hosts and x3config files.
