Hi Ulf,
to reproduce this:
1. Create a pipe
mkfifo /tmp/fifo
2. Start the writer:
tcpdump -i lo0 -n -w /tmp/fifo
3. Start the reader:
ethereal -i /tmp/fifo
Then you should see the packets in ethereal... Starting tethereal
instead
of ethereal works.
Best regards
Michael

Ulf?
Hmm, yes I've noticed some mails that there are problems with
capturing (or reading?) from a pipe :-(
As I'm usually working on windows where this isn't possible, I don't
have a lot of experience with it.
I'll take a look on my debian box, so could someone explain (or point
me to info) how to use the pipe "mode" ... or even better add this
info to the wiki (if it's not already there).
Is this all about reading from a pipe, capturing from a pipe or even
both?
BTW: Please don't expect any changes since sometime at the weekend,
I'm currently very busy.
Regards, ULFL
