Alfred, I'd like to say "thanks" once more.
I tried with newer ciphers and version 1.2 - and now freeradius (3.0.16) indeed sends me the second "challenge". So, it's a huge progress.
However it still complains on the unknown TLS version. I attach the server log and the packet capture, just in case.
Have a lovely day! -- Thanks and regards, Irina Ilina-Sidorova On 03.03.2020 12:25, iilinasi wrote:
Thank you Alfred! Yup, I used old ciphers indeed. I suspect it stops even before checking them, but I'll add newer ones and let you know. This is the relevant part of freeradius log, just in case: -- (1) eap_tls: TLS_accept: before SSL initialization (1) eap_tls: TLS_accept: before SSL initialization (1) eap_tls: <<< recv TLS 1.3 [length 0048](1) eap_tls: >>> send TLS 1.0 Alert [length 0002], fatal protocol_version(1) eap_tls: ERROR: TLS Alert write:fatal:protocol version tls: TLS_accept: Error in error (1) eap_tls: ERROR: Failed in __FUNCTION__ (SSL_read): error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol (1) eap_tls: ERROR: System call (I/O) error (-1) (1) eap_tls: ERROR: TLS receive handshake failed during operation (1) eap_tls: ERROR: [eaptls process] = fail -- On 02.03.2020 14:15, Alfred Arnold wrote:Hi,I'd like to understand, how does OpenSSL get to the idea of "0304" version, if there is no such abyte sequence in the packet...My question is: how OpenSSL determines the TLS version? How to debug it?I don't see any TLS 1.3 in the capture as well, but I see that your client is using only outdated (if not to say: historic) cryptographic algorithms: RC4, RC2 (never seen that in practice!), 3DES and DES. And those even combined with export options to weaken key strength. Many modern servers are configured to disallow such outdated crypto: make your client use at least - AES128/256 (either in CBC or GCM mode) - TLS 1.2 - no export cipher suites Then you might get a more positive reply from the server...
