Not really. s_time exists for TLS testing but unfortunately doesn't support DTLS. There is also ssltest which isn't part of the installed files but is contained in the test directory. That does have some DTLS support and could *possibly* be used for this purpose - but both client and server are in the same process and communication is in memory, not via the network. Matt
