Forces a poll of a remote BNU system.
uupoll [ -gGrade ] [ -n ] SystemName
The uupoll command forces the Basic Networking Utilities (BNU) to poll the remote system specified by the SystemName parameter. The command is usually run by the cron daemon or by a user who wants to force a job to be executed immediately. Otherwise, remote systems are polled by the uudemon.poll command at times scheduled in the /etc/uucp/Poll file and the /var/spool/cron/crontabs/uucp file.
Normally, the uucico daemon contacts a remote system only at times specified in the Poll file or when there is a job queued for that system. The uupoll command queues a null job for the remote system and then invokes the uucico daemon. This forces the uucico daemon to contact the remote system immediately and attempt to send any jobs which are queued for that system. Use the -g flag to specify that only high priority jobs be sent.
Use the -n flag to queue the null job without starting the uucico daemon. Use this option to:
The SystemName parameter is required, and specifies the name of the remote system to be polled.
|-gGrade||Instructs the uupoll command to send only jobs of the given grade (specified by the Grade parameter) or higher on this call. Jobs of a lower grade will remain in the queue until the next time the remote system is polled.|
|-n||Queues the null job, but does not invoke the uucico daemon.|
0 1,7,16 * * * /usr/bin/uupoll heraThis polls system hera at 0100 hours (1 a.m.), 0700 hours (7 a.m.), and 1600 hours (4 p.m.) daily.
0 1,7,16 * * * /usr/bin/uupoll -n zeus 0 5,12,21 * * * /usr/bin/uupoll -n hera 5 * * * * /usr/sbin/uucp/uucico -r1This queues null jobs for the remote sites on the hour, and they are processed by the uucico daemon when it runs at 5 minutes past the hour.
