If anyone out there has experienced any kind of trouble with bogus IP options issued by IBM's secure xenix during ftp's with SunOS 4.1 machines (or for that matter, any other machines) please let me know by email. --gregbo

The secure xenix sends fixed length IP headers - 32 octets - 12 bytes of padded zeroes with no options. I have no idea why, but it causes the Suns to immediately reboot, and as the Sun is trying to reboot, the xenix machine begins retransmitting its last packet causing the Sun to begin rebooting again. This continues until you reboot the xenix machine. We contacted Sun and have received to patches which corrected the problem on the Sun end. I'm still not sure about the xenix 32 octet IP headers. The patches from Sun are #s: 100077-02 and 100149-01. Sun will mail these out to you if you report the problem. Our contact was Arlene at Sun Support (415) 336-6034. Dave Miller dtm@mitre.org

Greg: Maybe you mean Datagrams with protocol type = 91 (in the field where TCP = 6)? This is called LARP from Locus computing. Everyone should feel free to give Locus a very hard time about not documenting this in an RFC. --jon.
