4.I have installed freeradius(mysql moudule) with pptp vpn in different servers,they work fine,but in my vpn server( radiusclient server) , the log file shows that "pppd[3359]: rc_avpair_gen: received unknown attribute 85 of length 4: 0x0000003C". and the "radiusd -X" show nothing wrong. Does it matter?
