I have to explain to someone the possible problems
that might be encountered by using old software on a 
machine in the internet.

One thing that came to mind is that it's possible this role
might include some 'firewall' type duties.

can someone explain to me the problem that was hinted at recently,
to do with malicious fragmentation of packets, so as to
get them through a firewall, and have them re-assemle on the other side..
I seem to remember it had something to do with getting a session
to open from the outside or something..

(p.s. I need this info pretty quickl (as per normal))

(I.P.Spoofing is another thing I'm sorta curious about..
I guess there may be CERT notes on these right?)

(got a cert URL?)
