Wireless Access

Hi everyone. I found some interesting information while analyzing controller. Does anyone know about problem presented at the attached picture... I suspecting it as UTF 8 encoding, but cannot understand the reason of this issue.

What version of ArubaOS is this?

cjoseph,

ArubaOS 6.3.1.13

Hi, 

We've seen this before. The error is caused by client http request to the controller with a URI that is not understood by the controller's web server.
The error is harmless but if the client is requesting a lot of odd URI's, the client needs to be investigated as what it's trying to access.
Sometimes browser addons will try to access certain URIs from a frequently visited site which includes the controllers' web UI.

Thanks,

Ok, I understood that..
Actually, it's little strange, because clients don't have any access to controller...
Also, regular wireless client doesn't have any information about controller.

The Client is 10.78.30.18 as per the log message. You may need to investigate this IP address. 

is there any way to decrypt that string?

I don't think there is an option for that on the controller. May be a packet capture on the client side could help.
