Hi: I built wireshark 1.12.5 from source on my ubuntu Linux, trying to use the DTLS decryption function. From "Enabled Protocol" i can see DTLS is enabled, but in the protocol preference tab, i don't see "DTLS", and right click on a captured DTLS packet, the "protocol preference" menu is grayed out. The downloaded windows version 1.12.5 works fine though. Unfortunately i have to use Linux to capture packets. Any idea why i can't set DTLS protocol preferences?

Thanks lei

Thanks for your answer, i will try that. Meanwhile, How do I perform decrypt after capturing packet? my DTLS is pre-shared-key, and i put the psk in the protocol preference of the wireshark, but the packet still show as "encryped application data".

Thanks Lei
