Just some misc one off standalone scripts for things. Scripts are all standalone.

Scripts

observium-to-dns_ptr.py

Query observium API for IP addresses known. Will spit out a bind style PTR zone based on router interface names. We use this to import into our dns zones to have nice and accurate traceroutes.

Works for ipv4 and ipv6, has some config options but defaults to adding ip4 and ip6 to entries. Attempts to use standard shorthand names for interfaces. Works well with Cisco and Juniper interface names as-is, further configurable.

Sample output:

$ ./observium-to-dns_ptr.py -n 10.20.8.0/24

push-configs-via-observium-group.py

Take config from a local text file and push it to network devices using NAPALM. Uses observium group ID's to choose devices. Ie if you have a group for some specific vendor type (Juniper, Cisco) you'd give it proper config for that platform

Sample output:

$ ./push-configs-via-observium-group.py -g 36  -c policy-standards.txt

Password for username 'falz' required to connect to Observium API and to log in to devices.

Password:

Merging the contents of 'policy-standards.txt' into group 36, which contains 6 devices..
