Greetings,
can somebody help me?
I am writing some perl scripts (ActivePerl 5.6.1 on a Win2K system) that perform tests on network devices. The basic structure of these scripts is : start (asynchronously) a tethereal capture, perform some operation on devices, stop the trace, analyze the trace.
I'm using the Win32::Process package but the kill method look unreliable (for small traffic the capture file is empty, it looks like tethereal or the underlying libpcap perform a sort of buffering and I don't know how to force a disk write). For longer traces I miss the latest packets and the last packet is almost always corrupted.
Tethereal autostop conditions don't look suitable: in general I cannot predict the running time of the script or the number of packet to capture.
A stop condition triggered by a capture filter would be very helpful, but as far as I know is not implemented yet.
I noticed that typing CTRL-C on the console where tethereal is running make it exit gracefully (but, alas, it's a manual operation).
Thank You
