Nas requirements

Use NAS tools like radtest to find out whether the radius server or your implementation causes problems.

SyCes uses a RADIUS server for centrally authenticating users and for accounting. Authentication of users against RADIUS is described by RFC2865. How accounting is done is described in RFC-2866.

These are the specifications for implementing a Network Access Server (NAS) that communicates with SyCes:

  1. No Keep-Alives

No Keep-Alive packets should be sent to test if the server is alive. This adds to load without providing useful information. Monitoring will be done by Synergy Systems GmbH. In case of a system crash the team willl start working on regaining the functionality anyway.

  1. Password (shared secret)

Transactions between the client and RADIUS accounting server are authenticated through the use of a shared secret with a minimum length of 16 characters. It should be possible to change it. It is used for both authentication and accounting.
