[SCION] SIG Configuration

[Chandrashekar Dheeraj]

Hello Cedric


Yes, I'm trying to setup a SIG between ASes 130d and 130e.

I had setup the SIG before the SCION upgrade, but not able to do it now.


I tried to give the remote IP address in sig.toml, also tried the default IP still not reachable.


- I remember previously when the SIG was working, I had defined a SIG section in topology.json file and assigning a IP address

  which basically tells the AS to run SIG on that IP address, so that the remote AS can connect

  But, I lost the topology.json file after the upgrade and I cannot seem to remember the part.

Its the same after assigning the IP addresses and adding routes.


Regards

Dheeraj

Hi Dheeraj

I’ve corrected the link, the component was renamed to “posix-gateway” upstream. Thanks for letting us know.

As for the SIG operation itself, are you trying to set this up between the hosts running ASes 130e and 130d? If so, I noticed two things:

- The sig.toml uses the IP address of the remote host for connecting to the scion-daemon, and vice versa on the other host. Is the intentional?
- The sig devices have no IP address assigned

If that is not helping, or you are setting this up on completely different hosts, then kindly ignore my comments — but may I suggest putting your sig.json, sig.toml, network interface setup and routes into a gist or similar and post it here? That way somehow with more knowledge about the SIG can follow-up.

Best,
Cedric
