Wireshark · Ethereal-users: [Ethereal-users] Cannot open tcpdump output

[Steve Fink <steve@xxxxxxxx>]

In my first attempt at using ethereal, I have run into two problems:

1. I wrote a dump file with
        tcpdump -i lo -s 1500 -w port8080 port 8080
ethereal says it's in a format it cannot understand.

# tcpdump -h
tcpdump version 3.4
libpcap version 0.4
Usage: tcpdump [-adeflnNOpqStvx] [-c count] [ -F file ]
                [ -i interface ] [ -r file ] [ -s snaplen ]
                [ -T type ] [ -w file ] [ expression ]

# ethereal -v
ethereal 0.7.7, with GTK+ 1.2.6, with libpcap

# uname -a
Linux foxglove 2.4.9 #4 Sat Dec 1 17:17:37 PST 2001 i686 unknown

0000070 10ec 0000 0000 0301 0003 9340 3c1e 3b38

2. Whenever I attempt to get ethereal to capture output for itself,
the capture window pops up blank and never says anything afterwards.
If I set it to realtime display, it initially pops up with text in the
window (all numbers are set to zero), but X never refreshes it.

What am I missing?

Thanks,
Steve
