decoupled accounting

Hi, I just made the setup of a second RADIUS server, and trying to relay the accounting, preferably with decouple-accounting, because I think it is a more robust configuration. I have already read the freeradius.org pages, a lot of posts, and the virtual server itself; put the decouple-accounting in sites-enabled; managed to intercept the accounting setting up the write_detail.xxxx server, and indeed all the correct accounting goes to /var/log/freeradius/radacct/detail.xxx I also setup on the master side, this secondary server as client in the clients.conf file. However, I am a bit at a loss how to reach the read_detail.xxx server to process the files left by write_detail. Any clues? Regards, Rui Ribeiro
