The problem is in the processing of their SSL/TLS Server Hello message
so they probably have a bug in their implementation of RFC 2246.
We are never getting to the point in the SSL/TLS handshake where
certificates are used. We are simply waiting for them to indicate
which cipher suites to negotiate.
You are going to have to figure out this problem with their technical
support in conjunction with the openssl-users@openssl.org mailing list.
Subscribe at http://www.openssl.org. The problem you are facing is
not in C-Kermit. It is apparently an incompatibility between the
version of OpenSSL you are using and the SSL/TLS implementation used
by WS_FTPD.
