However, it does not escalate its precedence when I open a 'finger' TCP connection to it. (it does request High Throughput, though, which I didn't send). Recent discussion of TCP and Precedence reveals that RFC-793 and MIL-STD-1778 disagree as to whether an actively-opening TCP can raise its precedence. One authority I've talked to thinks the MIL-STD is right, and the opener can raise, but not everyone has been heard from. Sorry, I am not yet equipped to play with IP options, but I'll keep the fuzzies in mind when I start (Basic Security first). jbvb
