Hi,
If the output is from some sort of trace tool you could write a dissector which could strip off those octets. Do they contain some meaningful information ?
Packet length?
Which TCP port(s) are used ?

Subject: [Ethereal-users] Decoding with an intermediate non recognized layer

Hi, i have captures of messages following next stack: Phy / Eth / IP / Tcp / 2 octets / SCCP / RANAP ..., the problem is layer between TCP and SCCP, consisting of two octets, an unrecognized format that makes impossible decoding upper layers, which are known for Ethereal.
Is there any way to configure an : ignore these two octets an continue decoding from there', or something similar to avoid this 'layer'?
Maybe some kind of output manipulation to overwrite these octets with some dummy, but known, header like M3UA...?
I would thank any idea, i'm new in Ethereal.
