hello! i have ubuntu 10.4 and freeradius-server-2.1.10 Recently i made some changes to the users file, to be able to register users via their MAC addresses in which use the following syntax : jesssi cleartext-password :="chispas" service-type= framed-user, framed-protocol =ppp, # framed-ip-address = 172.163.1.12 # framed-ip.netmask = 255.255.255.0 # framed-routing = broadcast-listen, # framed-filter-id="std.ppp", # framed-mtu =1500, Called-Station-Id = "00-0F-CF-BC-2A-9A:3Com", (this is the line that adds) Calling-Station-Id = "00-17-37-FA-B2-EB", (this is the line that adds) framed-compression = van-jacobsen-tcp-ip someone could help me or give me a different syntax to add the mac addresses in the users file? thank you -Viridiana Ambriz Robles
