Trust

As is outlined in this LiveOverflow video, trusting information is hard.

Note that I disagree with some of the key talking points in the video, as you will see later on in this guide.

My credentials, as of time of writing:

• Security+ certified
• Linux admin for over a decade
• Professional Linux admin for about 6 years

Debian/Ubuntu + Active Directory/LDAP v2

This is another quick write-up on getting Debian/Ubuntu to play nicely with LDAP groups. This includes logins, sudoers, home directories, default shells, the works.

This is tested and working on Ubuntu 18 and 20.04 and Windows Server 2016. This setup assumes you already have users/groups in AD/LDAP and have a basic understanding of users/groups.

While this guide is written toward Debian-based systems, some tweaks and downloading the appropriate PBIS script will allow this to work on any Linux-based system.

More techniques - caching apt packages network-wide

This guide runs through setting up AptCacherNg on a proxy/server to provide apt caching to clients. The client proxy scripts allow for multiple proxies, and account for proxies being offline.

Note that, for obvious reasons, this only works on Debian-based machines (Ubuntu and derivatives as well).

Server (the cache/proxy)

Note: you will need port 3142 open to the clients using this cache/proxy
