Our SunOS 3.3 system needed another kernel mod for traceroute to work. In netinet/ip_icmp.c, icmp_input() only hands a few types of incoming ICMP's to listening sockets -- redirects and echo replies, but *not* the time-to-live expired or port unreachable errors that traceroute requires. The effect is just what you found, endless *'s. If you don't have source, you might try building a kernel with the ip_icmp.o in uc.msc.umn.edu:~ftp/pub/traceroute.tar.Z... note this is only for Sun-3's running 3.x (3<=x<=5).
