Hi I am trying to make communicate between client & server locally and getting following error,

SERVER sysadmin@BLTSP00023:~/workspace/abc/dtls$ ./tests/dtls-server Jan 18 15:21:51 WARN cannot verify peer

CLIENT root@BLTSP00023:/home/sysadmin/workspace/abc/dtls# ./tests/dtls-client 127.0.0.1 20220 Jan 18 15:22:11 � ��� ��ALRT setsockopt IPV6_PKTINFO: Protocol not available

And I verified IPV6 is enables in my system Please help me understand whare I am wrong

It's been a wile since I looked at libcoap and tinydtls, but I believe they are using IPv6. You can't use addresses like 127.0.0.1, as this is an IPv4 address. Try using ::1, which is the localhost address in IPv6.

Thank you, I changed commands to ./dtls-server and ./tests/dtls-client ::1 But I am not getting any output here, Am I missing something now also?

thecodemaiden commented 8 years ago

From looking at the source, it seems the dtls examples expect you to type something in at the client and see it received at the server. What is your input to the client?

Thanks I changed code into IPv4 at protocol level, After that it is working with below commands ./tests/dtls-server ./test/dtls-client 127.0.0.1 Sorry for late reply ..
