Equal-cost multi-path using Dublin traceroute

A graph with every hops found can be found there

For a graph with only the inside node of OVH can be found there

Utilisation

You need to install the requirements that are in scripts/requirement.txt

To trace all ip launch the trace.sh script.

Need to be run with sudo to work

It will restart where it stop in case of a error.

Trace

trace.sh will run traceroute.py with the default argument. traceroute.py can be found in the scripts folder.

traceroute.py will save the traces in the traces folders, but it can have two arguments.

python3 traceroute.py [address] [--local]

Also need to berun with sudo

If no address if given it will trace all the ip in the ip.json file. If the local flag is put the trace will be save in a folder named traces_local in other case all the trace will be saved in a traces folder.

Inside the traces folders there are saved in a directory named after there ip, them in a json file, named with the timestamp from when there were traced.

Graph

To make sens of the traces, there is convert_trace.py in the scripts folder

It will read the traces from the traces folder and write the images inside the images folder.

python3 convert_trace.py [-a|--aio] [--local] [-f filename] [-r address_source] [-d address_destination] [-c] [-o]

Without any argument, convert_trace will take every destination separetly and save each image in images/by_dest with the name (dest)_(most_recent_timestamp).png.

The -a | --aio is all in one, wich mean all destination in one graph. If -f not defined the images will be named *ALL_IN_ONE.png" and save in images

The --local will take the trace from traces_local instead of traces and save the images in images_local instead of images

The -f filename will overwrite the name of the image.

The -r is use to select only one source instead of the two by default. Can't be used with -a

The -d make an image of only one destination

The -c will put color one the graph. Really usefull (Recommended)

The -o (only work with -a) output only the hops from OVH.

Other parameter can be ignored.
