Up front, everyone, please forgive the rant I'm about to do... Since I did not see an immediate way for Snort to send syslog alerts to a remote syslog daemon, I went so far as to install a local syslog daemon on my WinNT4 Snort box just so I could "see" what type of data was being sent to syslog from Snort. I figured that if the Snort syslog output was sufficient for my needs, I'd configure the local syslog daemon to forward all messages to my main syslog server. Well, much to my surprise, Snort did not send *any* data to the local syslog daemon. So, I snatched the Snort 1.8.6 tar ball archive from the Snort web site and looked at the source. Who would have thought that the alert_syslog functionality under Win32 would be sending data to the local Event Log!!! Evidently, somewhere along the Snort development line, decisions were made to have Snort's alert_syslog functionality under Win32 send messages to the Event Log. Why?! Who knows. I figured that syslog meant syslog. If someone wanted Event Log functionality, then there would be an alert_eventlog output plug-in. Arghhhhh.... I run a mixed Wintel/*nix environment and having a syslog daemon around isn't an issue. The issue now is that Snort under Win32 does *not* send data to a syslog daemon -- either local or remote -- but only to the local Event Log. Enough of my rant. I've got Win32 code around that shows how to send messages to a syslog daemon, and the daemon does not have to be local; it can be remote. But I don't want to be in the business of modifying the Snort source code every time a new Snort version is released. Oh well... I guess that I'm off to pursue other means for handling/logging Snort alerts under Win32.

I was under the impression that you have to get some sort of syslog client and put it on the snort box. In Linux, syslog reads syslog.conf, and you can specify what alerts go where. Snort passes its alerts into syslog for processing. If you were to get something like Monilog, you could transmit the snort log files themselves via SETP or syslog, for example. -----Original Message----- From: L.

You can make it easy on yourself by making snort log to 'Local1' if you'd like. -----Original Message----- From: L.
