There's not a lot more to read. In essence, unless the client helo is too bit to fit into one TLS-record layer packet the length in the client hello is 4 bytes less than the length of the containing record, but here the difference is 2, which I don't know how to explain. Not relevant to your issue, just a tangetial oddity. > what tool are you using to extract the > > >> Handshake type: 01 (Client Hello) > >> Length: 00 00 9c (156) No tool. Just known structure of the TLS handshake packet. -- Viktor. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
