knockd dies if I 'suspend'

[Chris Moore]

When I close the lid of my laptop, it goes into 'suspend' mode.

When I wake the laptop up again, the 'knockd' process is no longer running.

This happens even if I close the lid for just a second, and wake the laptop up immediately.

"sshd" survives a 'suspend', even for 10 hours. I think 'knockd' should be similarly resiliant.

The main loop does the following:

 while(ret >= 0) {
  ret = pcap_dispatch(cap, -1, sniff, NULL);
 }

When I suspect, ret gets set to -1, the loop exits, and the program ends, with this message:

  pcap: recvfrom: Network is down

It should wait for the network to come back again, probably set up a new pcap, and start again.

that's "suspend", not "suspect" (!)

Is this still a problem with Dapper/Edgy ? Thanks.

[Vassilis Pandis (pandisv)]

obviously still an issue since no code has changed

Exact same problem and exact same fix as the original reporter.
The package should come with that script.
Thanks.
