image_server

README

This example application fetches a JPEG image from the server and saves it to the disk.

To run the example, first start the server like this

go run server.go -local 17-ffaa:1:c2,[127.0.0.1]:40002 -cert tls.pem -key tls.key

Then, start the client:

go run client.go -local 17-ffaa:1:c2,[127.0.0.1]:0

The local address can be omitted, in that case the application binds to localhost.

For an interactive mode that lets the user choose a path from all available paths add the -i flag:

go run client.go -local 17-ffaa:1:c2,[127.0.0.1]:0 -i

Make sure to replace the addresses with your own AS addresses and to set the TLS key/cert paths to point to your tls.key and tls.pem files.

Also, image-server must resolve to the SCION address on which you run the server. You can add image-server to your known hosts by adding the following line to /etc/hosts. (replace ISD-AS and IP with your actual address):

ISD-AS,[IP] image-server
