Unable to connect to my Radius Server . Test connectivity settings on Fortigate primary server fails

[srajeswaran]

Can you collect diagnose sniffer output and then fnbamd debug as suggested in below article?

says the invalid RADIUS SERVER.

10.76.0.1 is my fortigate LAN IP and 10.76.12.15 is my Radius SERVER

[RBA · Accepted solution]

Try with below command

diagnose test authserver radius "RADIUS SERVER" mschap2 username password

Server_name indicates the value of "name" field configured under FortiGate Radius Profile.

Also share the output of command "sh full-configuration user radius"

Hi @JOSIAH_BOZIAH 

Please take the sniffer on ports 1813 and 1812 and attach it here.

Regards,

[JOSIAH_BOZIAH]

Do I need to check Radius accounting under Administrative access, also the command just hangs, no output until I terminate it control C.

HI @JOSIAH_BOZIAH 

Thanks for the update.

Open two putty 

Please take the output of the below commands 

# diagnose debug application fnbamd -1

# diagnose debug enable

 In the second putty run the sniffer.

diagnose sniffer packet any "host x.x.x.x and port 1813 and port 1812" 6 0 a

where x.x.x.x is radius server IP

Please recreate the issue (test connectivity) while taking the logs.

After taking the logs please disable the debug command.

# diagnose debug disable

# diagnose debug reset

Regards,
