I didn't see anything on the website about bug tracking so I am going to
assume that posting to this list will get it to the right place.
Description:
I found that if I run tethereal -Nn -R http to filter http traffic with
reverse DNS it will only capture a few packets; somewhere between 1 and
10 then it stops capturing. If I run it without -Nn for reverse DNS it
will capture perfectly. After repeated straces it dies exactly the same
each time. I have included the last few lines of the strace and the
version info for tethereal and for the debian package.
Let me know if anyone else is seeing this or if it is
machine/environment specific....
Thanks,
Nick
