Wireshark · Wireshark-users: [Wireshark-users] Dump file format?

[Trevor Bosaw <bosawt@xxxxxxxxxxxxxxxx>]

Hey,

I have been examining data from a group that saves their packet data  
in a dump file.  Wireshark recognizes these dump files, but they are  
too large, and it crashes before it can finish reading in the entire  
file.  I have been able to split the files using the Unix command  
'split', but since this command obviously cannot read the dump format,  
it splits the file in the middle of a packet.

Now, I don't really care about the loss of this packet, as it is only  
one among thousands, but when I try to load the second portion of the  
file that was split, wireshark doesn't recognize it (since it starts  
with the second part of a packet, and not a new one).

Does anyone know what the wireshark dump file format is, and if so, if  
it's possible that I can manually open the second and on portions of  
the dump file, delete the second part of the packet, and load the rest  
into wireshark?

I am not sure if this will appear appropriately on other computers,  
but here is an example of a packet from the dump file:

‘√≤°`
P”Ceå	6åfl§ †	 
\E~kí@6ìÙÍ>É@J‚P£ƒZ«AD§O¶P–Ã

This is exactly one packet.
Also, here is a selection of the very beginning of the second part of  
the file:

Ø˛©P˙ÏÕR”Ce6	
fl§ †	 
\E˚øi@q«‹∂ú
Ö"Ñ©ØP‰Ó‡ì8=œΩP˝ = R”Cl6Ofl§ †	 
\EA¯É@4£¡ƒ'xÀ«Ä5-Ï.IT
R”Cû

£âP·ñÑrXÛ(‘PˇˇX’R”CB6<†	\fl§

6<†	\fl§ E(Û€@vèP°Í∆F”©®PÙü6Å 
∞

Again, this is just gibberish to me, so I really don't know exactly  
what to delete from the second file.

Any help would be very much appreciated.

-Thanks
