The strange thing is that if the hosts on those subnets initiate the connection to the 20, then communcation is established with no problem. One of the Suns in question is reporting 103104 messages < minimum length and so we have reason to suspect that the problem has to do with the length of ICMP packets. Apparently the Unix 4.2 which runs on the Suns doesn't accept ICMP packets which are less than 8 bytes long. Has anybody experienced this problem? A while back there was some mention about a large number of patches to the IP stuff in generic 4.2. I'm hoping that one of them addresses this. Many thanks, Clive Dawson -------
