netreport(1) -- Linux man page
NAME
netreport - request notification of network interface changes
SYNOPSIS
netreport
[-r]
DESCRIPTION
netreport
tells the network management scripts to send a SIGIO signal
to the process which called netreport when any network interface
status changes occur.
OPTIONS
- -r
-
Remove the current request (if any) for the calling process.
NOTES
If a program does not call netreport with the
-r
option before it exits, and another process is created with the
same PID before any changes take place in interface status, it
is possible that the new process will receive a spurious SIGIO.
