then then the file will appear at ~cottrell/public_html/graph-DRC-to-Africa.gif
It also creates two other files (for example):
- rawtraceroutes-DRC-to-Africa.txt, this is the raw traceroute data measu4red, for example a series of traceroutes of the form:

Problems
Accurately locating the routers can be difficult. We use Geo IP Tool as the default. We also looked carefully at hostip.info, however it provides locations for fewer hosts and is not more accurate for our purposes. Both systems use databases and are not very complete/accurate for router interfaces. We are also developing TULIP to provide Geolocation using ping RTTs. It is a very valuable check on suspicious locations provided by the database methods. When we find the locations of hosts for which database methods provide the wrong countries, we provide a simple lookup table with the preferred countries.
