Speaking of which, is anyone going to implement traceroute for UNIX which using icmp echo requests, instead of (semi-)random udp packets, as the ammo? This is one way which I think Microsoft out did the old UNIX implementations. The combination of the above and the below would give us the usefulness we want and the security we want. (I don't think the below would work with Van Jacobsen's traceroute 1.2) On Wed, 21 Aug 1996, Vadim Antonov wrote:
On itself, LSRR is a godsend to hackers (i can think of about a dozen of very nasty attacks using general LSRR). The only useful application for it is traceroute. Why don't router vendors provide an option to turn it off for everything but ICMP ECHO? --vadim
