Using Radius with ocserv
|
|
========================
|
|
|
|
For radius support the [radcli library](http://radcli.github.io/radcli/)
|
|
is required. The minimum requirement is version 1.2.0. Alternatively
|
|
the freeradius-client library can be used (1.1.7 is the minimum
|
|
requirement), but not all radius features may be available.
|
|
|
|
radcli uses a configuration file to setup the
|
|
server configuration. That is typically found at:
|
|
/etc/radcli/radiusclient.conf
|
|
and is best to copy the default installed as radiusclient-ocserv.conf
|
|
and edit it accordingly.
|
|
|
|
The important options for ocserv usage are the following:
|
|
```
|
|
dictionary /etc/radcli/dictionary
|
|
servers /etc/radcli/servers
|
|
```
|
|
|
|
The dictionary should contain at least the attributes shown below,
|
|
and the servers file should contain the radius server to use.
|
|
|
|
Note, that ocserv provides the 'NAS-Port' attribute to server,
|
|
which corresponds to the worker process PID value. This PID value
|
|
may change during accounting, and it is often desirable to prevent
|
|
any unique IDs generated by the server to include the NAS-Port
|
|
attribute.
|
|
|
|
|
|
Ocserv configuration
|
|
====================
|
|
|
|
For authentication the following line should be enabled.
|
|
```
|
|
auth = "radius[config=/etc/radcli/radiusclient.conf,groupconfig=true]"
|
|
```
|
|
|
|
Check the ocserv manpage for the meaning of the various options
|
|
such as groupconfig.
|
|
|
|
To enable accounting, use
|
|
```
|
|
acct = "radius[config=/etc/radcli/radiusclient.conf]"
|
|
```
|
|
|
|
and modify the following option to the time (in
|
|
seconds), that accounting information should be reported.
|
|
```
|
|
stats-report-time = 360
|
|
```
|
|
|
|
That value will be overriden by Acct-Interim-Interval if sent
|
|
by the server.
|
|
