rsyslog server does not send the ServerHello response back to the rsyslog client system within the scope of the TLS handshake.
Issue
- TLS Handshake Hangs Waiting for ServerHello Response
- There is an issue in utilizing rsyslog-gnutls where the rsyslog server does not send the ServerHello response back to the rsyslog client system within the scope of the TLS handshake. On the rsyslog client end of the spectrum when testing the TLS connection using gnutls-cli the client connection hangs indefinitely at the Client Hello. tcpdump captures show that no packets leave the rsyslog server within the scope of the TLS handshake. rsyslog daemon has been verified as running and the TCP socket is open. The configuration functions with Red Hat Enterprise Linux 6 and rsyslog 4. However, this same configuration does not function with Red Hat Enterprise Linux 5 and rsyslog 3.
