TLS error messages

#1 Post by xeon » 2015-01-31 02:39

Hello,

I'm using FileZilla Client 3.10.1-rc1 and it's still showing the ECONNABORTED error message whenever the server closes the connection. According to the changelog, these should be silenced now.

No, nothing has been changed wrt. this particular error.

What has changed is the reporting of GNUTLS_E_WARNING_ALERT_RECEIVED (-16), GNUTLS_E_FATAL_ALERT_RECEIVED (-12), GNUTLS_E_PUSH_ERROR (-53) and GNUTLS_E_PULL_ERROR (-54)

Hello,

There still appears to be an error message in FileZilla Client, when vsftpd triggers its timeout for idle connections. I've been told by you in the past, that this is harmless, but this error message would probably make most people think that something is wrong.

vsftpd 3.0.2:
12:05:04 Status: Connecting to 216.85.11.73:21...
12:05:04 Status: Connection established, waiting for welcome message...
12:05:04 Status: Initializing TLS...
12:05:04 Status: Verifying certificate...
12:05:04 Status: TLS connection established.
12:05:05 Status: Connected
12:05:05 Status: Retrieving directory listing...
12:05:05 Status: Calculating timezone offset of server...
12:05:05 Status: Timezone offset of server is 0 seconds.
12:05:05 Status: Directory listing of "/" successful
12:10:05 Response: 421 Timeout.
12:10:05 Error: GnuTLS error -110: The TLS connection was non-properly terminated.
12:10:05 Status: Server did not properly shut down TLS connection
12:10:05 Error: Disconnected from server: ECONNABORTED - Connection aborted

vsftpd 3.0.3:
11:48:14 Status: Connecting to 216.85.11.73:21...
11:48:14 Status: Connection established, waiting for welcome message...
11:48:15 Status: Initializing TLS...
11:48:15 Status: Verifying certificate...
11:48:15 Status: TLS connection established.
11:48:15 Status: Connected
11:48:15 Status: Retrieving directory listing...
11:48:16 Status: Calculating timezone offset of server...
11:48:16 Status: Timezone offset of server is 0 seconds.
11:48:16 Status: Directory listing of "/" successful
11:53:16 Error: GnuTLS error -15: An unexpected TLS packet was received.
11:53:16 Error: Disconnected from server: ECONNABORTED - Connection aborted

Edit: Looks like vsftpd 3.0.3 has another bug where it sends some plaintext error messages.
