poll

Poll(4) 						     Kernel Interfaces Manual							   Poll(4)

NAME

       Poll - Contains information specifying when the UNIX-to-UNIX Copy Program (UUCP) should poll designated remote computers

SYNOPSIS

       /usr/lib/uucp/Poll

DESCRIPTION

       The  /usr/lib/uucp/Poll	file  contains information for polling remote computers. Each entry in the Poll file contains the name of a remote
       computer to call, followed by a <TAB> character, and a sequence of hourly intervals expressed in digits. These are the hourly intervals	at
       which the local system polls a remote system; you must specify interval times as digits between 0 and 23. The format of entries in the Poll
       file is: sys-name<TAB>hour

       Note that you must be logged in as root to edit the Poll file, which is owned by the uucp login ID.

       The Poll file is used with the crontabs/uucp file, the uudemon.hour script, and the uudemon.poll script.  Together, these files are respon-
       sible for initiating automatic calls to remote systems to perform certain maintenance tasks.

EXAMPLES

       The  following  example provides polling of computer eagle every 4 hours: eagle	   0 4 8 12 16 20 The follwing example provides polling of
       computer hera every hour: hera 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

FILES

       Contains all the configuration files for UUCP, including the Devices file.  Describes accessible remote systems.  Initiates file  transport
       calls  to  remote  systems.  Polls remote systems listed in /usr/lib/uucp/Poll file.  The uucp file that contains instructions for the cron
       daemon.
