Codice: Seleziona tutto
Errore: Errore GnuTLS -50 in gnutls_priority_set_direct: La richiesta non è valida.
Errore: Non è stato possibile inizializzare TLS.
Errore: Impossibile collegarsi al server
Cosa può essere?
Cercando in rete ho trovato poco. La cosa che mi fa pensare è che hanno interotto il supporto a tls1.0, ma almeno un server so per certo che ha anche tls 1.1 e 1.2
Nella documentazione di proftpd vedo questo
Question: My FTPS client has trouble connecting to proftpd using SSL/TLS, with the following error appearing in the TLSLog:
mod_tls/2.1.2[9628]: TLS/TLS-C requested, starting TLS handshake
mod_tls/2.1.2[9628]: unable to accept TLS connection: received EOF that violates protocol
mod_tls/2.1.2[9628]: TLS/TLS-C negotiation failed on control channel
Is this a bug in mod_tls, in the client, or something else?
Answer: There might be several different causes for this error. It could be a bug in the OpenSSL library, in mod_tls, in the FTPS client, or it could be a transient network issue.
The usual culprit for the above error is an FTP-aware network device such as a NAT, router, or firewall between the client and the server. Such network devices "peek" into the FTP control connection in order to dynamically open the necessary ports for data transfers. However, this "peeking" fails once an SSL/TLS handshake starts on that same control connection, and when that happens, these network devices usually terminate the control connection, resulting in the EOF ("end of file") error reported.
