uucpd daemon — Invoke uucico for TCP/IP connections from remote UUCP systems
Format
uucpd [–l seconds] [–x debug_level]
Description
The uucpd program allows remote uucico programs to communicate with local uucico in order to perform file transfers via TCP/IP connections. inetd starts uucpd when the remote uucico connects to the UUCP port. uucpd manages the login sequence with the remote uucico. After successful login, it then starts uucico to complete the transfer.
uucp stream tcp nowait OMVSKERN /usr/sbin/uucpd uucpd -l0
Options
- –l seconds
- Sets the login timeout value in seconds. When seconds are specified as zero, the login will wait without timing out.
- –x debug_level
- Invoke uucpd and uucico with
the –x option. debug_level indicates
the level of detail (0 has the least detail
and 9 has the most detail). The uucpd login
sequence debug output is written to a file in TMPDIR with a
filename beginning with uucpd and followed by randomly generated
characters. The uucico debug output is written
to the uucp logfile.
Guideline: When using the –x option, the UUCP logfile should be monitored so that it does not become too large and fill up the file system.
The Permissions file provides an alternative method for setting debug for connections on a system-by-system basis. See the section on Permission file in z/OS UNIX System Services Planning for more information.
Usage notes
uucpd is not affected by the locale information specified in locale-related environment variables.
