Subject:     Re: TCP SYN attacks


My preferred approach is to not even have to store state on any
of the embryonic connections.  And to implement the fix on all
of my hosts.  And customers can implement it in a firewall, if
they choose (and have boxes which can't be fixed: Win95, NT, Macs, ...).

Avi,

Did you mean to state that these boxes can't be fixed (hardened against
SYN attacks) by you?

Ted L.

My statements are my own and not of the Microsoft Corp. 

If I had Win95 or NT source I suppose I could harden them w/out
a SYN-handling proxy...

Ditto for MacOS (if that's what it's called).
