hi list,
i wonder whether anybody run into this scenario before and has a hint=20
how to resolve it...
my DrayTek Vigor 2200W router mangles UDP-based traceroute, i.e. the=20
only hop that is listed is the router/gateway itself -- then it gets=20
pitch black :(
when running =B4traceroute -I bla.foo.bar' (thus forcing traceroute to=20=
request ICMP echo replies) all works well.
but this is not the problem since i can put traceroute the options i=20
want it to get. xtraceroute is the problem because it *always' runs the=20=
UDP-way of tracerouting... and thus gets no useful information.
anybody with a nice idea how to solve this?
tia & cheers,
timo=
