Hello Rasmus, It seems that your beacons do not connect correctly to the central server. Please verify that the TCP connexion between the central server and you clients is active. Are you using the IPv6 beacon 1.0 with the ipv6 patch or did you enable it only with --enable-ipv6 ? I am asking that because IPv6 is only officialy supported from the 1.1 version. Mickaël
