Terminal servers provide the ppp protocol already, and authenticate via Radius, or Tacacs. > you use RADIUS and I was just wondering whether there are any implications > with using just PPPD as opposed to RADIUS. You're comparing apples and oranges here. pppd is the protocol used to send TCP/IP over a serial line (encapsulation). Part of its job is authentication between two sites (using CHAP or PAP). Normally for ISPs, the authentication is one way -> ISP authenticates the dialup client. Some implementations of terminal server software in linux (mgetty) auto-run pppd when it detects ppp frames being sent by the client. Some other implementations like portslave actually have radius authentication hacked into the ppp daemon so that if you run portslave on a PC server, it's as if its a terminal server in itself. so, pppd -> daemon that implements tcp/ip encapsulation protocol over serial/dialup lines with built in authentication based on PAP/CHAP. may come with a hack that uses radius for authentication radius -> purely an authentication/accounting protocol, used for network/isp auth/acctg. _ Philippine Linux Users Group.
