Party Authentication and Accounting Software FAQs

Q9. RADIUS authentication is not working. How can I troubleshoot

RASExpress and RADIUS problems?

A9. If you are dialing into the CommPlete Server using a PPP dialer (such as Win95

Dial-Up Networking) try to dial in using a terminal program.

Dial into the rack using HyperTerminal (or any other terminal program). Log into

the RASExpress Server manually. If you can log in and get to a RASExpress

menu, the RASExpress Server is communicating with RADIUS. There could be

an incorrect setting in RADIUS that is not allowing the remote user to connect via

PPP, or possibly PAP authentication is turned off in RADIUS.

If dialing from a terminal program works, try to dial in using the Win95 dialer.

Before dialing in, change the Connection Settings so the Terminal Window will

appear after connection. Dial out using the Win95 dialer, but then type the

Username and Password manually. Then choose Option #1 (PPP Session) and

click the Continue button. If this works, there is a problem with PAP

authentication and RADIUS.

If this doesn't work, you may have an IP assignment problem. If you are using

DHCP IP addressing, try setting a static group of IP addresses in the

RASExpress Server. Telnet into the RASExpress Server and change the IP

assignment type to Address Pool. Configure the RASExpress pool to use 24 IP's

that are available on your network.

Make sure that you have RADIUS as the security type on your RASExpress

Server. Also be sure the Primary Server IP address is pointing to your RADIUS

server. The Secret password must match the password you have configured in

the RADIUS server. Also, make sure the IP address of the RASExpress Server

and the Key are in the RADIUS Clients file. The Client Name must be the IP

address of the RASExpress Server (not the server name). The Key must be the

Secret Password that you have set in the RASExpress Server security section

(case sensitive).
