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:
uudemon.poll
uudemon.hour
uudemon.admin
uudemon.cleanup
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.
How to Start UUCP
To activate the uudemon.crontab file, do the following:
- 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.
To configure a role with the Primary Administrator profile, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
- Edit the /usr/lib/uucp/uudemon.crontab file and change entries as required.
- 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:
Calls the uusched program to search the spool directories for work files (C.) that have not been processed. The script then schedules these files for transfer to a remote machine.
Calls the uuxqt daemon to search the spool directories for execute files (X.) that have been transferred to your computer and were not processed when they were transferred.
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:
Runs the uustat command with p and q options. The q reports on the status of work files (C.), data files (D.), and execute files (X.) that are queued. The p prints process information for networking processes that are listed in the lock files (/var/spool/locks).
Sends resulting status information to the uucp administrative login by using mail.
uudemon.cleanup Shell Script
The default uudemon.cleanup shell script does the following:
Collects log files for individual machines from the /var/uucp/.Log directory, merges these files, and places the files in the /var/uucp/.Old directory with other old log information
Removes work files (C.) seven days old or older, data files (D.) seven days old or older, and execute files (X.) two days old or older from the spool files
Returns mail that cannot be delivered to the sender
Mails a summary of the status information that was gathered during the current day to the UUCP administrative login (uucp)
