Poll(4)								      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 comput-
  ers. 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 sys-
  tem 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<&lt;TAB>&gt;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 responsible for
  initiating automatic calls to	remote systems to perform certain maintenance
  tasks.

EXAMPLES

   1.  The following example provides polling of computer eagle	every 4
       hours:

       eagle   0 4 8 12	16 20

   2.  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
