[openssl-dev] need clarification on openssl s_server s_client applications

DTLS standard: DTLS does not permit fragmentation of the data (handshaking has it’s own fragmentation mechanism separate from the record layer).

See https://tools.ietf.org/html/rfc4347#section-4.2.3

Hi,

When I try to send any data > MTU (1500) from s_server/client
applications (in DTLS mode), I see an error (errno:90) on the sender
side. Is it normal? Is it a limitation of the s_server/client
applications or the OpenSSL implementation or the DTLS standard
itself?

I'm using Openssl-1.0.2g on Ubuntu-14.04


Thanks,
Balaji M
