bat - error looking for SCION dispatcher socket

[thomasgruebl]

Hi,

I've successfully set up and configured two SCION ASes, and I can ping them, exchange sensor data using the scion-sensorfetcher, and I can test the bandwidth with the scion-bwtestclient. However, scion-bat does not seem to work properly. Whenever I try to get data from my server using the following command:

scion-bat https://<my_other_AS>,127.0.0.1/home

I get an error saying:

The local directory /run/shm/dispatcher does indeed not exist. Do you know if I'm missing a configuration step?

All scion services are running properly:

Thanks for your help!

Best,

Thomas

Hello Thomas, it seems that you are running an old version of the scion-bat binary. In principle, the latest version should work with the new scionlab binaries.

You can run

sudo apt install scion-apps-*

Hi,

thanks for your swift response. I have tried that but it didn't work.

Also, I'm on arm64 and apparently the latest version that I can pull for arm64 is 3.5.1 and not 3.5.2.

Do you think this could be an issue?

Hello,

At least I would expect you have some other problem with that version, but not the one you were seeing here

For more interactive feedeback, we can use our Elements public room for SCION developers. https://matrix.to/#/#dev:matrix.scion.org. Feel free to follow up there.

We updated version 3.5.2 also for arm64 which solves the issue.
