After upgrading SSL Orchestrator to version 5.x, traffic gets reset, SSL Orchestrator hangs, and tcpdump analysis indicates that connections are being reset due to SSL handshake timeout exceeded.
SSL Orchestrator hangs on that connection, unable to bypass traffic until the connection times out. Other connections handle traffic during this interval.
-- SSL Orchestrator configured. -- Initial plaintext traffic resembles SSLv2 hello message or has less-than-enough bytes for SSL to process.
None.
This release adds a db variable to enable/disable SSLv2 hello parsing. It is called tmm.ssl.v2compatibility and is disabled by default.
