Hello, I have an older eMac in my lab I am using to test the PAM module (pam_radius-1.3.17) and have been able to compile by changing the Makefile to use: gcc -bundle pam_radius_auth.o md5.o -lpam -lc -o pam_radius_auth.so for the final linking of the shared object. The resulting .so seems to work except the password hashing comes out garbled on the server side and debug output indicates: Server Side: WARNING: Unprintable characters in the password. ? Double-check the shared secret on the server and the NAS! Client Side: pam_radius_auth: packet from RADIUS server 192.168.2.4 fails verification: The shared secret is probably incorrect However I've gone over the secrets on both side more times than I can remember, I even slipped in a debug message into pam_radius_auth.c to report the secret to make sure the file (/etc/raddb/server) was parsing properly. The secrets are identical, which leaves me to think that there's something about the crypto algorithm that's not matching between the client and server and I have successfully tested using PAM on the Linux machine that hosts the server (Ubuntu 7.10). Any suggestions or pointers as to where the problem may lie are greatly appreciated. -alex
