Ubuntu 12.04 with winbox issue...

Hi dude,
i just installed 3 ubuntu 12.04 LTS, but i notice there is some issue…

when i connect to the routerboard, there is no issue i can login via the ip.
but when i scan the routerboard via winbox, it’s shown me empty…

if, there is connection like ping or traffic flow, i able to scan and see the routerboard via winbox.

any advice on this?

Try disabling your firewall if you have one.
