### README
# to install needed modules on debian:
# * apt-get install libnet-whois-ip-perl libperlio-gzip-perl libdancer2-perl libnet-dns-perl libnet-traceroute-perl libdbi-perl libdbd-sqlite3-perl
### vars

### README #########################################################################################################################################
# This is the client for the XTR (XiCoN Trace Route). It opens a port and listening to HTTP requests. It answers with a traceroute
# in a json hash. The hash contains for each hop the IP, the PTR, the request time and the AS (Autonomous System).
#
# This client also tries to connect to a "master server" which helps keeping track of all the traceroute clients and their availability.
#
# This software uses the iptoasn database (https://iptoasn.com/) to determine the AS for each hop. 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.
#
# For now, the traceroutes are only IPv4. This will change in the future.
######################################################################################################################################################
### INSTALL ########################################################################################################################################
# This is a standalone software which usually runs in the "foreground". Starting it in a screen session or via init.d/systemd/rc.d is
# highly recommended. For testing, starting this script in a screen session is also fine.
#
# Either install all listed modules with "cpan -i <module>" or use your system's package manager (apt, yum, yast).
#
# On Debian just install there packages:
# libnet-whois-ip-perl
# libperlio-gzip-perl
# libdancer2-perl
# libnet-dns-perl
# libnet-traceroute-perl
# libdbi-perl
# libdbd-sqlite3-perl
# libdata-validate-ip-perl
