Hi all, After giving up my Openssl 0.9.8k, I've installed Openssl 1.0.0c version with latest patches for dtls support. All went well. After that, I tried to search for some DTLS tests (other than openssl s_server/s_client) and this is what I found :
http://sctp.fh-muenster.de/dtls-samples.html I've compiled the source from 'DTLS Echo Server and Client' and tried to run the binary (in my case './dtls_udp_echo'). # ./dtls_udp_echo -h ./dtls_udp_echo: invalid option -- 'h' Usage: dtls_udp_echo [options] [address] Options: -l message length (Default: 100 Bytes) -p port (Default: 23232) -n number of messages to send (Default: 5) -v verbose -V very verbose I get some errors. It's strange for me how comes that, depending on the specified arguments, I get two different errors: I case : # ./dtls_udp_echo 127.0.0.1 SSL_connect: Connection refused error:00000000:lib(0):func(0):reason(0) Unexpected error while writing: 5 error:00000000:lib(0):func(0):reason(0) II case : # ./dtls_udp_echo -p 23232 -V 127.0.0.1 SSL_connect: Connection refused error:00000000:lib(0):func(0):reason(0) Connected to 127.0.0.1 ------------------------------------------------------------ Segmentation fault Wireshark shows the beginning of dtls negotiation, but it's clear that after these errors, it stops. Does someone know the correct usage of this sample? I'm out of ideas! Thank you in advance!
