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.
