# xtr
This is the server for the XTR (XiCoN Trace Route). It's more of a master browser for the clients, so an web frontend can get a list of all the
available clients combined from one auto-updated source. It opens a port and listening to HTTP requests (GET and PUT). It can list all online and
offline clients. It also accepts new client entries via a PUT request (target client address in database has to be the request ip).
This is the server for the XTR (XiCoN Trace Route). It's more of a master browser for the clients, so an web frontend can get a list of all the available clients combined from one auto-updated source. It opens a port and listening to HTTP requests (GET and PUT). It can list all online and offline clients. It also accepts new client entries via a PUT request (target client address in database has to be the request ip).
The server keeps the list of clients up2date with checking their availablity with each request of all online clients.
For now, only IPv4 clients are supported. This will change in the future.
This software uses the MaxMind GeoLite2 database (https://www.maxmind.com) to determine the AS for each hop. To lookup the AS information the script
uses the MaxMind perl module which uses the MaxMind DB library.
This software uses the iptoasn database (https://iptoasn.com/) to determine the AS for each client. To keep track of all ip to asn relations, this software creates a local database file "ip2asn.db", which is a simple SQLite3 database with an index for faster searches.
This product includes GeoLite2 ASN data created by MaxMind, available from <a href="http://www.maxmind.com">http://www.maxmind.com</a>.
For now, only IPv4 clients are supported. This will change in the future.
