[c-nsp] Need old version of IOS for Cat3550 24-port EMI switch

[Joel M Snyder]

Folks:

I'm working on an IPS test for Network World and we're trying to 
validate some of the attacks.  There's a particularly tasty stateless 
SNMP-based attack that some of the IPS devices are missing, and now we 
need to "fact check" to see that they are, in fact, letting bad 
datagrams through.

The proof of the pudding is in the crashing, so we're trying to find one 
of the vulnerable versions of IOS for a Cat3550 to see whether the 
attack actually works.

Unfortunately, Cisco takes vulnerable stuff off of their web site, so 
it's not so easy to find this version if you don't happen to be still 
running it (and I'm not).  Does anyone out there have any of the 
following versions they can let me have?  I suspect SMI or EMI version 
will be equally useful.

Thanks!
