Has anyone tried to get timestamp from routers by RFC781 ip timestamp option? Or is their any tool that utilizes this IP option? I've modified ping progam so that IP timestamp option is set, but: (1) If option flag is set to 3 (i.e. timestamp for only prespecified addresses), it seems all routers simply ignore it. (2) If option flag is set to 1 (i.e. address and timestamp all the way), routers actually do timestamping. Especially when I ping a ROUTER itself with flag=3 timestamp option, with their own address prespecified, no router seems to give their timestamp. But when I ping a HOST (I 've tried Solaris,FreeBSD) it does answer. CISCO documentation says IP timestamp option is implemented, so I'm wondering... bye -- H.Taniguchi (taniguti@ntttqn.tnl.ntt.co.jp)
