Sending ClientHellos results in TLSAbruptCloseErrors

[tyll]

I would like to send ClientHellos with tlslite but I get TLSAbruptCloseErrors when trying to get the server's response. Can you please help?

script:

#!/usr/bin/python -tt
# vim: fileencoding=utf8

import socket


import tlslite

    def __init__(self, sock):

                             cipher, 52, 58]
        print ciphers
        client_hello.create(version,

You could ask for help on the mailing list, I'm not sure this is a tlslite issue though.
