ID-INT Debug/Traceroute Tool

This tool sends an empty UDP packet with an ID-INT header from a client to a server. The server responds with a UDP packet containing a fresh ID-INT header and the original ID-INT header from the client as payload.

Use with this fork of SCION.

To build just run go build.

Usage

Run the server in one AS

./idint-traceroute --sciond [fd00:f00d:cafe::7f00:54]:30255 --local [fd00:f00d:cafe::7f00:53]:32001

and the client in another

./idint-traceroute -sciond 127.0.0.60:30255 -local 127.0.0.1:32000 \
  -remote 2-ff00:0:222,[fd00:f00d:cafe::7f00:53]:32001 -encrypt \
  -nid -inst0 RTT_NEXT_BR --inst1 EGRESS_LINK_TX -inst2 INGRESS_TSTAMP -inst3 INST_QUEUE_LEN

If idint-traceroute can't key keys, make sure the local address in the command above matches the address the SCION daemon (which idint-traceroute uses) responsible for the AS you want to run id-int-traceroute in.

If the border routes can't get level 1 keys, make sure their IPs are allows for idint keys in the drkey.delegation section of the control service configuration.

To select the path and run continuously use the -i (interactive) switch. Also see ./idint-traceroute -h.
