Hi all, I'm trying to monitor my radius servers using The Dude by Mikrotik. Here, there's not a prebuild check, but there's a radius test, made in UDP on port 1812, where I have to manually set the "sent string" and the "received string". How is a radius request made, or where can I find some docs about it? When I send a request with the default string, on the radius I receive: Wed Jan 14 08:55:45 2009 : Error: WARNING: Malformed RADIUS packet from host xxx.xxx.xxx.xxx: packet attributes do NOT exactly fill the packet Wed Jan 14 08:55:55 2009 : Error: WARNING: Malformed RADIUS packet from host xxx.xxx.xxx.xxx: packet attributes do NOT exactly fill the packet Wed Jan 14 08:56:30 2009 : Error: WARNING: Malformed RADIUS packet from host xxx.xxx.xxx.xxx: packet attributes do NOT exactly fill the packet Thanks, Andrea

I have no idea what that means.

The NAS is completely broken. Tell the manufacturer that you want a firmware fix so that it will implement RADIUS correctly, *or* return it for a refund, and buy a real NAS. Alan DeKok.

Thanks, but this is not a NAS. This is a monitor application for various servers (http, ping, smtp, pop3, ...). http://www.mikrotik.com/img/thedude.jpg The problem is that for the radius test, there's not a prebuild test as for other protocols, but I need to specify the string to send to freeradius, to simulate the RADIUS protocol. Do you know if there's some docs about the RADIUS protocol or radius packet syntax? Otherwise, do you know other software to monitor some radius servers? In other words i need a software to simulate a NAS, and if the radius doesn't respond can send a warning mail to me. Thanks, Andrea

Then it's not doing RADIUS, and telling it to send packets to a RADIUS server is wrong.

As I said, I have no idea what that means. You are coming into a RADIUS mailing list, and using terminology that is specific to a particular product from a particular vendor. I've never used that product from that vendor. Using that terminology here is confusing an unnecessary.
but I need to specify the string to send to freeradius, to simulate the RADIUS protocol.
If you think you can create a static string to simulate RADIUS... it doesn't work that way.
Do you know if there's some docs about the RADIUS protocol or radius packet syntax?
The web site is full of documentation. It contains copies of the RADIUS specifications, which explain the protocol in detail.
Otherwise, do you know other software to monitor some radius servers? In other words i need a software to simulate a NAS, and if the radius doesn't respond can send a warning mail to me.
Perhaps you read the documentation that comes with the server, and the FAQ. It contains examples of using test programs. Alan DeKok.
