Starting UUCP

UUCP includes four shell scripts that poll remote machines, reschedule transmissions, and clean up old log files and unsuccessful transmissions. The scripts are as follows:

These shell scripts should execute regularly to ensure that UUCP runs smoothly. The crontab file to run the scripts is automatically created in /usr/lib/uucp/uudemon.crontab as part of the Solaris installation process, if you select the full installation. Otherwise, the file is created when you install the UUCP package.

You can also run the UUCP shell scripts manually. The following is the prototype uudemon.crontab file that you can tailor for a particular machine:

#ident  "@(#)uudemon.crontab    1.5     97/12/09 SMI"
# This crontab is provided as a sample. For systems
# running UUCP edit the time schedule to suit, uncomment 
# the following lines, and use crontab(1) to activate the
# new schedule.
#48 8,12,16 * * * /usr/lib/uucp/uudemon.admin
#20 3 * * * /usr/lib/uucp/uudemon.cleanup
#0 * * * * /usr/lib/uucp/uudemon.poll
#11,41 * * * * /usr/lib/uucp/uudemon.hour

Note –

By default, UUCP operations are disabled. To enable UUCP, edit the time schedule and uncomment the appropriate lines in the uudemon.crontab file.

ProcedureHow to Start UUCP

To activate the uudemon.crontab file, do the following:

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Edit the /usr/lib/uucp/uudemon.crontab file and change entries as required.

  3. Activate the uudemon.crontab file by issuing the following command:

    crontab < /usr/lib/uucp/uudemon.crontab

uudemon.poll Shell Script

The default uudemon.poll shell script reads the /etc/uucp/Poll file once an hour. If any machines in the Poll file are scheduled to be polled, a work file (C.sysnxxxx) is placed in the /var/spool/uucp/nodename directory. nodename represents the UUCP node name of the machine.

The shell script is scheduled to run once an hour, before uudemon.hour, so that the work files are in place when uudemon.hour is called.

uudemon.hour Shell Script

The default uudemon.hour shell script does the following:

By default, uudemon.hour runs twice an hour. You might want uudemon.hour to run more often if you expect high failure rates of calls to remote machines.

uudemon.admin Shell Script

The default uudemon.admin shell script does the following:

uudemon.cleanup Shell Script

The default uudemon.cleanup shell script does the following:
