["Gilbert Ramirez Jr." <gram@xxxxxxxxxx>]

Perhaps we should include a modified libpcap source tree in
the ethereal distribution until wiretap can capture packets,
to make sure the Linux timeout bug and the lex-restart bug
are fixed for Ethereal.

I'm working on the wiretap capture routines right now, but they won't
be ready for the next few ethereal releases.

BTW, on my system, RedHat 6.0 Linux ix86, I was not able to
reproduce Roberto's problem.

Hi, Gilbert!

 The tests work ok. And I tried to make a capture under my own account
 now, and it worked. Sorry to report a non existing problem. I'm
 pretty sure this *was* happening, but I can't reproduce it right now.

 I think this was happening with.... Wait a minute!

 [a few minutes later]

 Ok, what I saw might be related to the libcap's buffer flush error.
 This is how you can, hopefuly, reproduce it:

 - run ethereal
 - open the capture windows
 - fill the filter with an invalid entry 
 - parse error
 - reopen the capture window
 - remove the filter (delete)

 There, capture goes ok, but there is a "The file /var/tmp/ether...
 does not exist".

 It happens as root, too. I was induced to error because when it
 happened I always restarted etherealas root, and it was a fresh
 session without any parsing error.

Regards, Roberto
