Status(4)						     Kernel Interfaces Manual							 Status(4)

NAME

       Status, .Status - Contains information about the status of the uucp program contacts with remote systems

SYNOPSIS

       /usr/spool/uucp/.Status

DESCRIPTION

       The /usr/spool/uucp/.Status directory contains information about the status of the uucp program contacts with remote systems.

       For  each remote system contacted, the uucp program creates a file in the .Status directory called SystemName, where the SystemName file is
       named for the remote system being contacted.  In the .Status/SystemName file, the uucp program stores the following  information:  Time	of
       the last call in seconds Status of the last call Number of retries Retry time, in seconds, of the next call

       The  times  given  in  the .Status/SystemName file are expressed as seconds elapsed since midnight of January 1, 1970 (the output of a time
       system call).  Thus, the retry time is in the form of the number of seconds that must have expired since midnight of January 1, 1970 before
       the  system  can  retry.  To make this entry in the .Status/SystemName file, uucp performs a time system call, adds 600 seconds, and places
       the resulting number of seconds in the file.  If the last call was unsuccessful, the uucico daemon will wait until the  time  specified	by
       the retry time before attempting to contact the system again.
