Hi I am trying install the PAM_RADIUS_AUTH on a Solaris 10 server to use RADIUS for user authentication. I have managed to successfully compile and install the pam plugin. When I tried to telnet to the machine from a different server I am getting the following error. Failed looking up IP address for RADIUS server radius1 (errcode=12) I have made a host entry for this server name in /etc/hosts file and able to ping the RADIUS server with name. But still its not working. Could you please help on resolving this.
