I am actually running RedHat Linux 6.2 on Intel 486dx-100! Guess I didn't
wait for tethereal to capture 4096 bytes and thus the file size appeared
zero. So is there something I can do so that the output doesn't get
buffered???
thanks

Tethereal does not buffer output, it writes it immediately. What you're
probably
seeing is a side-effect of buffering from the stdio routines in C library.
By default output is buffered; for example, on my Linux system, data is
written
to the file every 4096 bytes. Once you stop tethereal, any remaining
data is flushed out of the buffer to the file, too.

Hi there,
I am using tethereal[the command line version] with a capture filter and
writing the output to a file with the '-w' switch but tethereal doesn't dump
to the file till I kill the tethreal process. I notice the size of the
output file to be zero till I actually kill tethereal.
Wondering if there is any way I could get it to dump to the file while
capturing itself. This way I could see if there are any packets that match
the filters ....
thanks
