hi,

my apologies if this is the wrong place to send this.  I didn't see
anywhere else to submit bug reports on http://www.tcpdump.org/

I notice that when I record a tcpdump 3.61 using 'tcpdump -w ...' and then
try to read it back using 'tcpdump -r' the following strange thing happens:

if I read the file in using 'tcpdump -r' the sequence numbers on tcp
packets are one off from the sequence numbers when I read the file using
'tcpdump -r src hostname'.  Here's an example:

% tcpdump -w t.o tcp and port 5001 &
% ttcp -t -s tuesday
% (kill tcpdump)
% tcpdump -r t.o | fgrep 15:37:40.281973
15:37:40.281973 monday.1120 > tuesday.5001: P 46337:47785(1448) ack 1 win 
39062 <nop,nop,timestamp 102779314 102780069> (DF)
% tcpdump -r t.o src monday | fgrep 15:37:40.281973
15:37:40.281973 monday.1120 > tuesday.5001: P 46336:47784(1448) ack 1 win 
39062 <nop,nop,timestamp 102779314 102780069> (DF)

As you can see, the start and end sequence numbers reported are one off 
from each other when I specify a src filter than when I don't specify one.

Anyone else seen this, and if so, is there a bugfix for it?  Thanks
  - Mike Schwartz
