Hi Alan, Ok, seems the default install is dated that comes with CentOS 4.4... I've upgraded to FreeRADIUS Version 1.1.7 now and logging seems to be working but I'd like to be able to get more usable data. I nthe /etc/syslog.conf file I have this entry: # .* will log all messages in the same log file local1.* /var/log/radius/radius.log From the syslog server I see this data: Oct 17 19:11:16 radius radiusd(pam_unix)[15776]: authentication failure; logname= uid=95 euid=95 tty= ruser= rhost= Oct 17 19:12:06 radius radiusd(pam_unix)[15776]: authentication failure; logname= uid=95 euid=95 tty= ruser= rhost= Oct 17 19:12:26 radius radiusd(pam_unix)[15776]: authentication failure; logname= uid=95 euid=95 tty= ruser= rhost= Oct 17 19:13:52 radius radiusd(pam_unix)[15776]: authentication failure; logname= uid=95 euid=95 tty= ruser= rhost= But I'd like to see the User_Name and Client_Name similar to what you in localhost:/var/log/radius/radius.log file. Thanks again,
