Hi all, I am having some problems in trying to write a little module to handle some custom attributes. Because I have a project regarding very specific requirements I preferred to write a module instead of trying to use the existing ones, so I can know in a better way where to go to change things when I want a different behaviour.
What I am doing right now is trying to have a testbed with a client, a proxy and a server, exchanging some custom attributes saved in the users file of the server and transmitted with auth-accept messages. The proxy should intercept these new attributes and save them in a specific syntax in a local file. I managed to create and transfer successfully the custom attributes and to have them saved in a local file by the proxy. The problem is that if these attributes have a string as a value, there is no problem in reading it using the field vp_strvalue. If these attributes have the attribute ipv6address, when I try to access to them using vp_ipv6address I get a segFault. The values are correctly stored in the packets because I can see them with wireshark and the client receives them successfully. In the documentation (the wiki) there is written to access the attributes through request->packet->vps but I managed to do it only with request->reply->vps. (initially I wanted to save this local file using the post-proxy section because I was thinking that it was the best place to do it (it's an action to do when the proxy receives the reply from the server) but I couldn't access the right packet through the API and so I found out that I could do it in the post-auth phase) I would not want to disturb you too much but the problem is that it seems to me that there is a bit of lack in the documentation regarding how write modules in the newer versions of freeradius and so I didn't know other places to look (I have been looking at the source code for all the day but maybe I can do it faster if pointed into the right direction) Thank you in advance for any answer, Best regards, D'Avella Stefano Bell Labs Alcatel-Lucent Centre de Villarceaux Route de Villejust 91625 NOZAY
