### README #########################################################################################################################################
# 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.
#
# 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.
#
# For now, only IPv4 clients are supported. This will change in the future.

### CHANGELOG ######################################################################################################################################
# v0.4 (2019-08-22)
# * ADD: added better documentation
# * ADD: list of API commands via API
# * FIX: replaced bug-driven LWP::* with HTTP::Tiny
# * FIX: limited adding of clients to source ip of target entry (only add a client which you are coming from)
######################################################################################################################################################
### 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:
# libperlio-gzip-perl
# libdancer2-perl
# libdbi-perl
# libdbd-sqlite3-perl
# libdata-validate-ip-perl
#
