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 responsible for
  initiating automatic calls to remote systems to perform certain maintenance
  tasks.

       hours:
