Some of our neighbors run BRL VAX Unix and wanted to network to our machines, without buying anything. So, I handed them an obsolete Xerox 3-megabit Ethernet board from our stockpile and connected it up for them. Their vax won't talk to the two of ours that are on that net. We tried a 3-meg board in another neighbor's Eunice vax and it won't talk to us either - but it *will* talk to the BRL Unix vax. Our if_en.c has conditionals to swab header and data of IP packets, all packets, or none. SWABALL is what's currently in effect. The BRL Unix machine does not appear to be doing any byte swabbing at all. One of us is using the wrong byte order. Which of us is it? Does it have anything to do with the V-kernel 'enetfilter' hooks scattered throughout if_en.c? Don Speck speck@cit-vax.arpa
