Hrm. Upon inspection, all logs are coming in with just the hostname, so that's a dead end. All normal syslogs (like cron.info, kernel.notice, daemon.debug, etc.) I can see are being spoofed and sent on to the SIEM, but the logs generated by imfile (all configured as news.info) from client machines get logged on the syslog server, but aren't being spoofed and sent on to the SIEM. -- Rick Brown Office of Information Technology Georgia Institute of Technology 258 4th Street N.W.
