Hi there We have set up our first Cisco ASA (8.4) to send syslog (TLS) messages through to graylog via
logging host outside ip.add.ress TCP/6666 secure We already have some Unix systems using rsyslog successfully doing the same thing, but the Cisco records aren't being accepted. A sniffer shows traffic coming in from the Cisco, but server.log reports the following. That sounds like the Cisco attempted to handshake TLS and then sent an alert to graylog stating the error was "certificate_unknown"? That would make sense, but our network group have no idea how to make the CA trusted. Can someone point me at something they need to read to do this properly?
