A couple of years ago I made modifications to the Berkeley ping to allow writing and reading of route-record packets. That is dimacs.rutgers.edu:~ftp/pub/ping.shar. I also found that 4.3BSD hosts didn't do the right thing per the RFCs with ICMP echo request packets that had record-route set (and by association, timestamp request packets also). dimacs.rutgers.edu:~ftp/pub/rr.shar are kernel changes to 4.3BSD to deal with that. Although I've submitted both back to Berkeley, I don't know if they've made 4.3-Tahoe, -Reno, or 4.4. I've also gotten a report of a portability bug for rr.shar, but haven't dealt with it yet (change the caddr_t definition of "opts" to u_char *).
