[ethereal-dev] Ethereal and tftp

[Richard Sharpe <sharpe@xxxxxxxxxx>]

Hi,

I must have been smokin some really good stuff when I did those mods for
the TFTP protocol.

I forgot that when I use ethereal, I am going to have a class full of
students who will all be monitoring TFTP sessions. So there will be at
least n/2 sessions going, plus possibly other UDP related stuff going on.

This means that I need a way to distinguish between them, and I should try
to remove the dissect_tftp routine from the dispatch table when I see the
last block of a tftp transfer.

As Guy suggested, I should probably include the (source and dest) IP
address(es) in the hash that I am constructing. I was thinking of a hash
where I simply add together, byte by byte, the SIP, DIP, SPORT, and DPORT.
Will this distribute the things across enough of the hash table entries?  I
don't whant too many collissions.


Regards
