RADIUS Authentication for Ubuntu
May 23, 2023 - Alex Roland
Local accounts on Ubuntu servers can be a hassle to manage, just as it is on routers and switches. We can solve this by configuring RADIUS authentication on the Ubuntu server, which will allow standard login and the sudo command to use your AD credentials. Read more to learn how to do this. I'll explain which files to modify, the package to download, and how to simplify the configuration changes with sed.
Automated ACL Management
August 22, 2022 - Alex Roland
ACLs, or Access Control Lists, are an important part of a network that consists of more than one LAN. When you only have a couple of routers and/or networks, managing the ACLs might not be that much of a challenge. Of course that entirely depends on the ACL and the environment, which is why I think it is important to automate your ACL management no matter the size of the environment. This way you are setting yourself up to be able to handle an expanding network.
