Are there any known problems in the 4.3 code dealing with IP options? I can't understand it.... Specifically, in routine ip_dooptoptions, file ip_input.c: 1) Strict source route with record appears to record an address for the receiving interface rather than the transmitting one. 2) Record route appears to route the datagram based on a garbage address, bouncing an ICMP "source route failed" if this fails or recording an address for the bogus transmitting interface if it succeeds. Are these bugs or have I missed something? Has anybody fixed them? Does anybody use IP options anyway? Do I have an out-of-date RFC? Thanks in antici... . . . pation, Jeremy Reference: RFC 791: IP protocol spec. Sept '81 pp. 20,21 "... address as known in the environment into which this datagram is being forwarded" (identical wording in two places) -- Jeremy Harris jgh@root.co.uk
