netreport (1) Linux Manual Page

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.
