Wireshark · Ethereal-dev: [Ethereal-dev] unsupported network type in capture file

[Nathan Jennings <njen@xxxxxxxxxxxxx>]

Hello,

I receive the following error using Ethereal 0.9.11 when I try to open a
certain capture file:

"The file <filename> is a capture for a network type that Ethereal
doesn't support."

The capture file was written by the default, IBM provided tcpdump
included with AIX 4.3. I've read other captures in Ethereal written by
this tcpdump previously, but these successful reads have been of
captures from the host's ethernet interface. The error message above is
generated when I try to read a capture from the host's loopback
interface (lo0).

I compiled/installed the latest tcpdump on my desktop and tried to read
the capture file. It outputs an error message as well, saying datalink
type 24 not found (maybe this helps?).

I was hoping someone might have some suggestions or guidance on how I
might modify Ethereal so it can read these capture files. I will
probably need to read/view capture files off this host's loopback
interface in the future, so I'd like to correct this if possible.

Thanks for your time,  -Nathan
