Traceroute to Solaris 2.x machines gives many timeouts.



Solaris 2.4 and later (and Solaris 2.3 w/ high rev kernel jumbo
patches) limit the number of ICMP error message to one
per 500 milliseconds. To switch off this feature, use:



/usr/sbin/ndd -set /dev/ip ip_icmp_err_interval 0


In Solaris 8 the rate limiting mechanism was changed and traceroute
will get all responses now as the new mechanism accepts short
burst even though the rate limit is still in effect.
