Something I just came across recently is I’ve had to switch to using “Machine” credentials with MikroTik RouterOS v7 devices instead of “network” credential types. I’m not 100% sure why this is yet, but something that will maybe help someone facing the same issue. Honestly I don’t have any v6 routers left to check this

Read MoreTransitioning from a traditional network engineer to an automation engineer can come with a steep learning curve. Terms like git, merge, squash, branch, and rebase can be daunting. While there are many “getting started” tutorials out there for git, it feels like most of them are geared toward programmers and those who have team members
Read MoreI have created playbooks for Ansible Network Device Backups. It is important to keep your device configurations backed up in the event of a hardware failure. Check out my GitHub for these Ansible playbooks. Some folks are starting to use Git for device backups as it provides diffs and backup capability. For those who don’t
Read Moretl;dr: Python2 strikes back! Always use Python3. Ran into this issue after an upgrade of AWX from 14.0.0 to 15.0.1, where jobs will just fail with no output in AWX showing what happened.

The only connection required is SSH between the “controller” node (the main AWX/Tower instance), and your remote node. This device can now do work for you in this remote network. The problem with setting these up is that I have yet
Read MoreThis will be a short post today, feeling pretty dumb. Just learned the hard way that Ansible variable names can not start with numbers. It even says so in the first line of the documentation on variables: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#creating-valid-variable-names You’ll get some pretty weird output if you try and start them with numbers.

Read MoreAn issue I ran into the other day when trying to setup Active Directory authentication in Ansible AWX, using LDAP auth type. These are a couple things that aren’t exactly called out in the documentation from Red Hat, and might not be obvious to all. You can use ldap:// if you aren’t setup for ldaps://
Read MoreAnsible doesn’t always have to be crazy complex playbooks doing super cool stuff. Sometimes, it’s really useful to get some output from al your devices like versioning, VLANs, IP addresses, etc… Here I plan to collect some of the one-liners I end up using so others can see what’s possible. This will be a dynamic
