netreport − request notification of network interface changes |
|
netreport [-r] |
|
netreport tells the network management scripts to send a SIGIO signal to the process which called netreport when any network interface status changes occur. |
|
-r |
Remove the current request (if any) for the calling process. |
|
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. |
