routeviews 0.1.3

CLI tools that support RouteViews.

Route Views requires many tools to support its functionality. This package is a place for those tools to live.

This package also acts as a python library for Route Views.

routeviews-build-peer CLI tool

This tool is for (consistently) updating the Route Views ansible inventory (private repo) when folks submit new peer requests.

This tool uses information provided by PeeringDB for the peering information.

Prerequisites

1. Route Views Ansible Inventory: You must have a local copy of the Route Views ansible inventory available, for this tool to update.
   • If you will be running this command with any regularity, is useful to export the ROUTEVIEWS_INVENTORY environment variable to point to your local copy of the Route Views ansible inventory repository (private).

   # (Optional) Place in your ~/.bashrc
   export ROUTEVIEWS_INVENTORY='<working-tree>/ansible/inventory'
   

   • <working-tree> refers to wherever you've cloned the repository on your filesystem.

Example: Peer with an ASN using IP Addresses

This tool supports arguments for asn, as well as ip. The ip argument can be used multiple times to peer with multiple IP Addresses at once.

⚠ Only supports peering with one ASN at a time.

ℹ Use the --help flag to learn more about how to use these arguments.

As discussed in the prerequisites, there is also the inventory argument required that points to the "inventory/" directory.

ℹ Tip: Provide an asn and omit the ip argument entirely -- the tool will attempt to peer with ALL compatible IP Addresses for the provided asn!

Example: Peer with an ASN (at ALL IXes)

If an ASN is wanting to connect wherever possible, provide only the asn argument and the tool will determine all the possible ip arguments from PeeringDB.

routeviews-email-peers CLI tool

This tool will get a list of email addresses for any networks that are actively peered with a particular Route Views Collector. This tool is for gathering email address information about Route Views Collector's peers around the world, leveraging PeeringDB and RDAP.

Future Plan: Use UO SMTP server to automate actually sending many types of 'standard Route Views Operations emails' (use Jinja2 Templates for the email templates).

Prerequisites

1. SSH Access: This script uses NetMiko, and assumes that the current user can SSH into the collector using SSH keys (recommend using an ssh-agent).
2. PeeringDB Account (Optional, if you would like this tool to search PeeringDB): Export your PeeringDB credentials as environment variables, PEERINGDB_USERNAME and PEERINGDB_PASSWORD:

   # (Optional) Place in your ~/.bashrc
   export PEERINGDB_USERNAME=rleonar7
   export PEERINGDB_PASSWORD=MySuperSecretPassword
   

(non)Anonymous access to PeeringDB API: Unfortunately, PeeringDB APIs only return the info we need when using a PeeringDB account, and not when using anonymous access.

Example

Run the routeviews-email-peers command against a specific Route Views collector, e.g. "route-views4.routeviews.org".

Today, this command will to produce a semicolon-separated list of email addresses for each (established) peering session on that collector.

$ routeviews-email-peers --collector route-views4.routeviews.org
> WARNING:root:No email found for ASN: 204028
> [e-mail]; [e-mail]; [e-mail]; ... trimmed for brevity...

YAML Python API

We have a custom YAML module for handling (Ansible) YAML config files. In particular, this module will handle whitespace matching the standard way used throughout the Route Views Infrastructure repo. Further, this module ensures that the order data dumped is the same as ingested.

Today, this functionality comes thanks to the ruamel.yaml package (PyPI)!

Example

This example loads a file by filename, then saves that file back.

In this case, this will essentially create a copy the "vars.yml" file.

ℹ Tip: The "vars2.yml" copy, or any file dumped using routeviews.yaml, will follow the Route Views YAML styling convention.

import routeviews.yaml

my_variables = routeviews.yaml.load('vars.yml')

# ... make updates to `my_variables`...

routeviews.yaml.dump(my_variables, 'vars2.yml')

Additional APIs

Besides the CLI tools discussed above, this package contains many internal packages/modules that might be useful.

⚠ NOTICE: Major version zero (0.y.z) is for initial development. Anything MAY change at any time. This public API SHOULD NOT be considered stable.

• There is the routeviews.peeringdb package that has some great methods for interfacing with the PeeringDB API.
• There is the routeviews.yaml module that can load and save YAML config files (without rearranging them).
  • Depends on the ruamel.yaml package
• There is the routeviews.ansible package, that can load, modify, and save the Route Views Ansible Inventory.
• There is the routeviews.bgpsummery module, that defines a BGPSummary class as well as functions for retrieving a BGPSummary from any collector.
• There is the (start of a) routeviews.api module/package, for interfacing with the Route Views API/DB (undocumented).

Release Notes

This project follows Semantic Versioning.

Notice: Major version zero (0.y.z) is for initial development. Anything MAY change at any time. This public API SHOULD NOT be considered stable.

0.1.3

• Fix Bug: routeviews-build-peer CLI tool rearranges the 'Route Views Peer Config' in the Ansible Inventory.
  • Now we track the 'order' of attributes whenever loading any routeviews.ansible.NeighborConfig class from a YAML file. That 'order' is then used when subsequently dumping the data, thus ensuring that nothing is rearranged unnecessarily!

0.1.2

• Bug: routeviews-build-peer CLI tool rearranges the 'Route Views Peer Config' in the Ansible Inventory.

• Fix PeeringDB Authentication!

  • See the relevant GitHub Issue where we discovered the following details about PeeringDB API Basic Authentication:

  1. Do NOT base64 encode
  2. Username/Password Must be space-separated (e.g., must not be colon ":" separated)
  3. Username when using API tokens is "Api-Key"
  4. Ensure "www" is in all API requests!

• Enable using PeeringDB API Key instead of username/password.

  • Exposed via --peeringdb-key argument in routeviews-build-peer CLI tool (or as env var: PEERINGDB_KEY).

• Add the filepath to the exception message when routeviews.yaml encounters a ParseError.

  • This enables fixing syntax issues very quickly.
  • "Unable to parse <filepath>" is the added message, seen below:

  ... omitted traceback for brevity...
  routeviews.yaml.ParseError: while parsing a block mapping
      in "<unicode string>", line 1, column 1:
          short_name: decix
          ^ (line: 1)
  expected <block end>, but found '-'
      in "<unicode string>", line 109, column 1:
          - peer_as: 8888
          ^ (line: 109)
  Unable to parse <working-tree>/ansible/inventory/host_vars/route-views.decix.routeviews.org
  

• Ensure that PyVCR cassettes do not contain HTTP Basic Authentication secrets.

  • Rotated the (randomly generated) Base64 encoded password that was previously exposed via HTTP Basic Authentication Headers.

0.1.1

• Fix Bug: Package failed to declare some critical dependencies.

0.1.0

Bug: Package failed to declare some critical dependencies. Was missing uologging and raumel.yaml dependencies deceleration in "setup.py".

The first release of the routeviews package contains some core CLI tools, as well as some functions/classes that might be useful to routeviews maintainers.

CLI Tools

Provide two CLI tools:

• routeviews-build-peer CLI tool: automation of updating "Route Views Ansible inventory", toward 'adding BGP peers to XYZ collectors'.
• routeviews-email-peers CLI tool: get list of email addresses actively peered with a Route Views Collector.
