ASN Database

{% alert %} Automatic download functionality is currently disabled to allow the beta to ship, it will be re-enabled when I can be certain it’ll work. {% /alert %}

Recommended Settings: If you’re not using ASNs, you don’t need to worry about the ASN database, nd don’t worry about making sure you’ve got the latest version all the time.

The ASN database is downloaded from the Route Views project.

This project does amazing work in assembling this data, however there are sometimes problems downloading it (stalled/slow connections), which can stall out the worker container.

Updating the Database

If you would like to upgrade the database to a newer version, it can be performed as follows.

You will need the “pyasn” package from pip installed. this will provide three utility scripts.

Or, if you’re on a Linux system, it’s normally bundled with “python3-pyasn” package for your distro, and can just run these commands from the cli after installing it.

## Download the full rib file
pyasn_util_download.py --latestv4 --filename latest.rib

## Convert that file to a usable format
pyasn_util_convert.py --single latest.rib asn_db

## Download the ASN Names file
pyasn_util_asnames.py -o asn_names

## This will give you two files - asn_db and asn_names

## Get the name of your web docker container
docker ps
## Look for the container name similar to "synclias-web-1"

## Copy the files into the web container
docker cp asn_db synclias-web-1:/app/shared/
docker cp asn_names synclias-web-1:/app/shared/

That’s it! The server will automatically pick up the files when needed.
