Hello, this is Alan Francisco with Engage Communication.
Please tell me if there is a way for Ethereal to decode an
SS7 message (FISU, LSSU, or MSU) preceded by an Ethernet header, IP
header, UDP header, and then a two-byte non-standard header.
Only if there's a protocol dissector for your non-standard header for
SS7-over-UDP.
I assume from "FISU, LSSU, or MSU" that this is MTP2-over-UDP. The
current version of Wireshark (Gerald moved to a new company, but the
old company had the Ethereal name, so development is continuing at
wireshark.org with the new name) doesn't have any MTP2-over-UDP
encapsulations, so you'd have to write a dissector for your
encapsulation and submit it to wireshark-dev@xxxxxxxxxxxxx in order
for Wireshark to recognize it.
(BTW, Gerald, Gilbert, and I are all on the ethereal-users and
wireshark-users lists; you don't need to send mail to us individually
if you're sending it to the users lists.)
