SDI's audlog allows to *download* logs from any machine (which runs ssyslog), using secure protocol, checking if logs are unchanged. But it doesn't provide a solution for a real-time analysis on a "central machine", the only thing which is possible is to add "download logs from all machines every 5 minutes and pipe it to logsurfer"-like entry to crontab.. or use unsecure-spoofable-sniffable UDP logging. Didn't check nsyslogd yet -- going to do it right now. By the way, if any of us are using logsurfer, probably we can try to create a database of logsurfers rules for a standard programs (sendmail, syslogd, kernel messages, and so on).
