Run "tac_plus-ng", a new TACACS+ daemon, on Alpine Linux with Docker.
This version of tac_plus-ng is a major rewrite of the original public Cisco source code and is in turn largely based on tac_plus from Marc Huber.
It has multiple useful features, like LDAP / ActiveDirectory / RADIUS backends and rule-based permission assignment.
Project URLs: https://www.pro-bono-publico.de/projects/ and https://github.com/MarcJHuber/event-driven-servers/
If you just want to use the container from docker hub, create the directories and configurations - then proceed with step 2.
docker build -t obtag/tac_plus-ng .
Just copy your tac_plus-ng configuration to "etc" directory or adjust your settings in the existing file "tac_plus-ng.cfg".
Hint: The sample configuration "etc/sample_tac_plus-ng.cfg-ads_working" is working well with Active Directory backend and logging. The AD groups "tacacs_admins" and "tacacs_readonly" can get access to network devices with different privelege levels.
Run the container with:
docker run --name tac_plus-ng -p 49:49 -v $(pwd)/etc/tac_plus-ng.cfg:/usr/local/etc/tac_plus-ng.cfg -v $(pwd)/log/:/var/log/ -d -t --restart=always christianbecker/tac_plus-ng
Configure your network devices to use the new TACACS+ service - example:
# Aruba CX switch
tacacs-server host 192.168.1.3
tacacs-server key plaintext "SECRET30CHARACTERTACACSKEY1234"
If you have enabled logging in your tac_plus-ng.cfg configuration file, all login attempts (failed or succeeded) are logged. The logging includes date, time, device, username, source of connection and status.
