Are you sure aboult sol2? I know there is a icmp patch for sunos
4.1.3_u1, which is vulnerable. I have seen no such sol2 patch, so I
assumed it was protected against such attacks (atleast 2.5/2.4 should be).

I hope AIX's protection isn't as poorly designed as Linuxes though. It
stops the original nuke, but not a easy to write variation of the same
tired theme.
