Draw graphs of all connections of a system of hosts based
on log files obtained by running ss -natpu -4 on each host.
For example give a list of hosts, the log could be gathered with the following command:
for dest in ulysse danae-bis atlas1 ulysse-bis; do ssh root@$dest "ss -natpu -4 " > logs/netstat-$dest.log ; done
NB: You may need root credentials to run netstat or ss.
It writes a csv gathering the whole platform connections. It writes an image + a dot file for each host processed. Nodes in diamond shapes represent LISTEN sockets.
