New issue 138 by [email protected]: Non TLS Connection to TLS
Listening Point hang
http://code.google.com/p/jain-sip/issues/detail?id=138
we found that SIP tls connections are not handled properly.
When we send plaintext message "\n\n\n\n" to SIPs (5061) socket, server
hangs out (did not response to the SSL handshakes anymore)
with "Unrecognized SSL message, plaintext connection?" (attached). HTTPs
(8181) refuse plaintext connections correctly.
Steps to reproduce:
telnet $host 5061
telnet $host 8181
(enter few newlines)
When we try to handshake with unsupported chipper, server just log
exception and connection hangs without server response. Connections to
https (8181) are refused correctly with "Secure Renegotiation IS NOT
supported".
Steps to reproduce:
$ openssl s_client -cipher EDH-DSS-DES-CBC-SHA -connect $host:5061
$ openssl s_client -cipher EDH-DSS-DES-CBC-SHA -connect $host:8181
(or whatever chipper unsupoprted by server)
