It lists the single nodes of a route and displays the quality of the connections in between. Finally it shows the needed effort to get a packet through the whole route.
The program uses ttl-manipulatet icmp-echo-requests to find the intermediate nodes and reads the udp-messages used and generated by the olsr-deamons to gather present information about the link-quality and neighbor-link-quality of node-node-pairs in the watched route. Due to this structure there is no instant information on a new node-node-pair. Until the information is available it is left blank and unregarded by the whole-route-etx. @@ -17,4 +19,4 @@ an olsr-plugin or the screen-output in something that can be diplayed graphical
