SCION Java examples

Send packet example

This is a simple example project that uses JPAN to send a packet to the SCION packet inspector.

To try out the example please download the stand-alone jar file through one of these options:

Then join on of the IETF's WLANs: ietf, ietf-hotel, ietf-dual-stack, or eduroam.

Then execute the example (requires Java 1.8 or later):

java -Dorg.scion.bootstrap.host=scion-ietf126.ddns.net -jar packet-example-0.5.0.jar "Your unique message"

Note: the bootstrap argument is only required because this is an experimental set-up.

JPAN CLI tool

JPAN-CLI is a tool that allows echo, traceroute, showpaths, ... and other functionality, similar to the SCION CLI tool. JPAN-CLI is stand-alone based on JPAN and does not require any locally installed SCION software. Here are some examples you can run, but first, to download the jar file:

wget https://github.com/netsec-ethz/jpan-cli/releases/download/v0.3.0/jpan-cli.jar

List the paths to ETH Zurich:

java -Dorg.scion.bootstrap.host=scion-ietf126.ddns.net -jar jpan-cli.jar showpaths 64-2:0:9

Only 10 paths??? Well, let's pass a parameter to list the first 100 paths:

java -Dorg.scion.bootstrap.host=scion-ietf126.ddns.net -jar jpan-cli.jar showpaths 64-2:0:9 -m 100

Or do a traceroute:

java -Dorg.scion.bootstrap.host=scion-ietf126.ddns.net -jar jpan-cli.jar traceroute 64-2:0:9,0.0.0.0

Other destinations to try:

  • ETH 64-2:0:9
  • Cambridge 71-20965
  • Cloudscale 64-2:0:9c
  • CSCS 64-2:0:c
  • Korea University 71-2:0:4d
  • University of Virginia 71-225
  • OvGU 71-2:0:4a

A list of reachable ASes can be found at the end of this document.

Other things to try

Additional examples

The project contains other examples, but they do not come with an executable jar file:

Troubleshooting

No DNS search domain found. Please check your /etc/resolv.conf or similar.

This happens, for example, on Windows when using a VPN. There are several solutions to this (aside from reconfiguring your system).

Solution #1: Provide search domain

This is useful if you have access to a search domain with a NAPTR record of the discovery server. You can execute the jar with the following property (on example of a search domain is ethz.ch. but it obviously works only when you are in that very domain):

java -Dorg.scion.dnsSearchDomains=<search domain> -jar packet-example-<version>.jar

Solution #2: Provide a discovery server

You can directly set the IP:port of the discovery server:

java -Dorg.scion.bootstrap.host=<IP of bootstrap server:8041> -jar packet-example-<version>.jar

Solution #3: Provide a topology file

If you have a topology file, you can do the following:

java -Dorg.scion.bootstrap.topoFile=<yourTopologyFile.json> -jar packet-example-<version>.jar
