Hello Guys, I am new in Freeradius server and also in linux and I need your help regarding the functionality of the server. I am currently using freeradius version 2.2.3 and my desktop computer is running the CentOS 6.4 linux operating. First of all, I've downloaded the uncompressed freeradius software package (freeradius-server-2.2.3.tar) from the freeradius website: http://www.freeradius.org from source code in the tar format. Then after I had to create a folder using CentOS linux in order to the freeradius server source code package to the folder, uncompressed and installed on the computer. After copied to the folder, I used the tar commands to uncompress the source code package and install it on the computer using #./configure, #make and #make install commands from the INSTALL file of the uncompressed server package. After installed, the configurations files of the RADIUS SERVER were found under /usr/local/etc/raddb directory path. i tested the server on the debugging mode using radiusd -X and at the end of the output i saw this line " Ready to process requests". I have first created a user inside the users file and I did the normal default testing with the debugging mode and the user was accepted. After that i change the clients.conf file putting my shared key and the IP Address of the switch and also configure ssh on the server side I have done the AAA , Radius and SSH configurations on the switch, then I used Putty on another computer to access to the server by putting the IP address of the switch . Is this the right way to access the server ? i ran the debugging mode on the server and try to access using putty on another PC . here is the result i got this : rad_recv: Accounting-Request packet from host 192.168.9.26 port 5001, id=151, length=122 User-Name = "testing" NAS-Identifier = "002389550a92" NAS-Port = 16781313 NAS-Port-Type = Ethernet Calling-Station-Id = "0000-0000-0000" Acct-Status-Type = Start Acct-Authentic = RADIUS Acct-Session-Id = "1100030205009" Framed-IP-Address = 192.168.9.25 NAS-IP-Address = 192.168.9.26 Event-Timestamp = "Apr 2 2000 12:00:06 ICT" Service-Type = Login-User # Executing section preacct from file /usr/local/etc/raddb/sites-enabled/default +group preacct { ++[preprocess] = ok [acct_unique] Hashing 'NAS-Port = 16781313,NAS-Identifier = "002389550a92",NAS-IP-Address = 192.168.9.26,Acct-Session-Id = "1100030205009",User-Name = "testing"' [acct_unique] Acct-Unique-Session-ID = "6ff6addd9c912e31". ++[acct_unique] = ok [suffix] No '@' in User-Name = "testing", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] = noop ++[files] = noop +} # group preacct = ok # Executing section accounting from file /usr/local/etc/raddb/sites-enabled/default +group accounting { [detail] expand: %{Packet-Src-IP-Address} -> 192.168.9.26 [detail] expand: /usr/local/var/log/radius/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/detail-%Y%m%d -> /usr/local/var/log/radius/radacct/192.168.9.26/detail-20140310 [detail] /usr/local/var/log/radius/radacct/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/detail-%Y%m%d expands to /usr/local/var/log/radius/radacct/192.168.9.26/detail-20140310 [detail] expand: %t -> Mon Mar 10 13:12:05 2014 ++[detail] = ok ++[unix] = ok ++[exec] = noop [attr_filter.accounting_response] expand: %{User-Name} -> testing attr_filter: Matched entry DEFAULT at line 12 ++[attr_filter.accounting_response] = updated +} # group accounting = updated Sending Accounting-Response of id 151 to 192.168.9.26 port 5001 Finished request 1.

Cleaning up request 0 ID 10 with timestamp +122 Ready to process requests. then i stopped the debugging mode. and run the server using this commands [root@chris raddb]# service radiusd restart Stopping radiusd: [ OK ] Starting radiusd: [ OK ] on the user's PC side i got access denied and the server does not report on the radius.log file . please help me and also correct me where ever i went wrong.
