Hi Marek,
I request you to please have mercy on me. I have to
communicate to SSL v3 Server using SSL v3 Client Hello Message. The following
is my client hello message:
<snip>
"\x01"
"\x03\x01" /* SSL Version */
"\x40\x7b\xab\xc0" /* GMT */
"\x32\x41\x52\xd3\x46\x63\xea\x22"
"\x37\x22\x33\x70\x2e\xfe\x80\x08"
"\xeb\x82\xe9\xcd\xba\x97\x84\xbd"
"\xd4\x8a\x9d\xe2" /* Random Value */
"\x00\x18" /* cipher specs length */
"\x00\x00" /* Session ID Length */
"\x00\x00\x33\x00\x00\x32\x00\x00" /* cipher specs data */
"\x35\x01\x00\x80\x08\x00\x80\x06"
"\x00\x40\x04\x00\x80\x02\x00\x80"
"\x02\x01\x00" /* Compression Method */
</snip>
I am somehow not getting GMT and random value details in ethereal. Is the above
stuff the right SSL v3 Client Hello?
Please help me out as i have to finish my project tomorrow morning!
Thanks and Regards,
Suchindra Chandrahas

This looks like SSL2 client_hello.
For that to work you must add SSL2 record header, in this case
two bytes {0x80, len} where len in length of handshake data.
You cannot use here SSL3/TLS1 record header.
And if you specified 16 bytes of chalenge/random data, you must add this
data to packet too.
Best regards,
