Thanks for all who helped. I had been having problems setting up RADIUS (all versions) on RH 4.2 to authenticated users dialing into a USR TC Netserver modem server. Radius always responded with the following message: unix_pass: password for <myid> failed Sending Reject of id ... to netserver I had everything configured as recommended by the docs and list members. It turns out the the minimum configuration required by Netserver are the following: User Password Framed-Protocol Framed-IP-Address Framed-IP-Netmask I had not specified a netmask before. Also used the command line to set the secret key (MD5 Key) of the Netserver. One thing though, I must start radius a few minutes before it starts responding to queries from Netserver or any other utilities such as testuser. I still can't figure out the reason for this. I don't think that it is a Linux issue since I wrote a small server program which receives input on the 1645 port and prints it out. The program had no problems with immediate response. Now I really have to dive into the rest of the stuff.
