Hi, Running FreeRadius 2.0.3 built from source on Centos 5.1 with a Mysql 5.0.45 back end. We've been doing testing on our setup for MONTHS (First FR1, now FR2) and its been flawless. Today we went to put our first unit into production and am having issues. We are reading NAS from SQL. The entry is : (3,'192.168.25.13','SBC-1918','other',0,'KhLcPALLdzTcJs3f','GLRXTAFLfhf3N4zT','First Install') From the user table I have : (1, 'tuc','User-Password',':=','PLAINTEXT') And when I run : #!/bin/sh (echo 'User-Name = "tuc"' echo 'User-Password = "PLAINTEXT"' echo 'NAS-IP-Address = 192.168.25.13' echo 'NAS-Port = 0') | /usr/local/bin/radclient -x localhost auth KhLcPALLdzTcJs3f I get : [root@ports ~]# sh TESTRAD User-Name = "tuc" User-Password = "PLAINTEXT" NAS-IP-Address = 192.168.25.13 NAS-Port = 0 rad_verify: Received Access-Reject packet from client 127.0.0.1 port 1812 with invalid signature (err=2)! (Shared secret is incorrect.) and in radius.log I see : Wed Apr 30 16:38:43 2008 : Auth: Login incorrect: [tuc/eY\261㡩\226`\305\020y\366/�?\333] (from client localhost port 0) HELP... I can't see what I'm doing wrong. Thanks, Tuc
