The problem of standard traceroute in TCP #9

Open xhdix opened 2 years ago

xhdix commented 2 years ago

In standard traceroute mode, most of the time the answer is just hop 255. But I set the maximum hop to 50.

The traceroute measurement has what is called a 'gap limit'. Basically, if there are 5 consecutive hops that have no response then traceroute will try hop 255 and stops.

The measurement code (this repo) supports different gap limits, but it seems that the Atlas user interface doesn't have that option at the moment.
