What would you like to do?
Use the module in the official FreeRADIUS v3.1.x branch, this Gist is kept only for history purpose.

Cassandra backend for FreeRADIUS.

Please make sure that in accounting section of the site config, cassacctsupplement appears before cassacct, cassauth should also be added to the accounting section to enforce Simultaneous-Use checks.

Neat. I've wanted to do that for a while, but thought there'd be issues about linking against a CPP library. Couldn't find any good articles on the subject.

If you'd like it included in the server, please add the GPLv2 license header as found at the top of this source file https://github.com/FreeRADIUS/freeradius-server/blob/v3.1.x/src/modules/rlm_always/rlm_always.c.

I'll handle reformatting the code, but you'll still be credited as the author (of course 😄).

is there a way to connect cassandra as a backend from rlm_perl only for accounting

i just need the RAD_REQUEST data to the Cassandra.

I made it in the way by the use of IO:Async and Cassandra CQL modules in the perl to write the data.

Is there any proper way in rlm_perl to do that.

Thanks

No, there's not, as that'd require FreeRADIUS to support asynchronous request processing, else there's no benefit to using the async IO AP. It's the direction we'll be heading in, but it is a significant amount of work.

If we did add asynchronous request processing, the SQL module would be one of the first to be rewritten to use it, so there'd be no benefit to using perl anyway :)

linnaea's module has now been merged into the v3.1.x branch (with some changes), and seems to work fine (locally at least). So if you want to use cassandra with FreeRADIUS that's your best bet.
