NS-25 Radius with SSH
I currently configured a Netscreen 25 to authenticate admin users via Radius Server but the connections aren’t being authenticated. The following message error is logged after trying to connect via SSH:
SSH: Admin ‘<my_username>’ at host A.B.C.D attempted to be authenticated with no authentication methods enabled.
The authentication via Telnet and Web Interface is working fine…
What can be wrong?

I got same problem. I am not able to access via SSH with Radius Authentication. If using web access is success. Below is my system details
Is there any bug for the OS?
Thanks & Regards
OK guys! Thanks for helping me!
Just to add to Tim’s comments, 5.0.0r8 was a really bad release. Recommend you upgrade to the latest 5.0.0, which is 5.0.0r11.
ScreeenOS 5.0.0r8 has a bug in it that will not work with Radius. Upgrade to 5.0.0r9
per the 5.0r9 release notes:
Here is the bug entry.
02986 – SSHv2 with RADIUS authentication failed to authenticate external
02044 – An operation using SSH version 1 to access the device failed when
using Radius for administration authentication.
The Screen OS in use is 5.0.0r8.0
The configurations related to Authentication follows:
set auth-server “Local” id 0
set auth-server “Local” server-name "Local"
set auth-server “Radius” id 4
set auth-server “Radius” server-name "RADIUS_IP_ADDRESS"
set auth-server “Radius” account-type admin
set auth-server “Radius” timeout 0
set auth-server “Radius” radius port RADIUS_PORT
set auth-server “Radius” radius secret "RADIUS_SECRET"
set auth default auth server "Local"
set admin ssh port SSH_PORT
set admin auth timeout 10
set admin auth server "Radius"
unset admin device-reset
set admin privilege get-external
set admin format dos
