What is radsecproxy?

radsecproxy is a generic RADIUS proxy that in addition to to usual RADIUS UDP transport, also supports TLS (RadSec), as well as RADIUS over TCP and DTLS. The aim is for the proxy to have sufficient features to be flexible, while at the same time to be small, efficient and easy to configure.

https://software.nordu.net/radsecproxy/

radsecproxy is used within the eduroam infrastructure at the federation or top level to securely proxy RADIUS requests between known eduroam Identity and Service Providers.

---

Changes in 1.8.2

• The container now runs as the radsecproxy user with UID=52000 and GID=52000 -- When inserting an external log file into the container, ensure the owner and group are 52000
• Now using Alpine as the base for improved security and significantly smaller image size

Custom -xeap2 Tag

Tags that end with the xeap2 suffix include the log patch that adds the Operator Name and Chargeable User Identity (CUI) attributes to the Access-Accept/Reject logs. Shout-out to Vlad Mencl, REANNZ, for creating the patch needed for the eXtending eduroam in Asia-Pacific (XeAP2) Project.

Example log:

Access-Accept for user [email protected] stationid 02-00-00-00-00-01 from SINGAREN_1 to 172.23.1.1 (172.23.1.1) (Operator_Name 1nus.edu.sg) (CUI f4334d537e2aa92876fc6ca902c57513c97bacaa)

For those using version 1.9.0, the CUI and Operator Name attributes are now built into the logs if present.

Access-Accept for user [email protected] stationid 02-00-00-00-00-01 cui f4334d537e2aa92876fc6ca902c57513c97bacaa from SINGAREN_1 to 172.23.1.1 (172.23.1.1) operator 1nus.edu.sg

How to use this image

• Create and place a radsecproxy configuration file in your desired directory to be mounted into the container on start-up. E.g. /etc/radsecproxy.conf
• Create a log file if you want logs to be saved on the Docker host machine : E.g. # touch /var/log/radsecproxy.log,

Start the container using the following command: (Make sure to replace the filepaths, timezone and Docker tag placeholders)

docker run -it --name eduroam-radsecproxy \
-p 1812:1812/udp \
-p 1813:1813/udp \
-e TZ=timezone #e.g. Pacific/Auckland \
-v /path/to/log/file:/var/log/radsecproxy/radsecproxy.log \ 
-v /path/to/radsecproxy.conf:/etc/radsecproxy.conf \
spgreen/eduroam-radsecproxy:tag
