Are you using snort with the option : snort -O ? snort -U stores local alert in UTC time, this may be the problem. ----- Original Message ----- From: "Bruno Sicchieri" <bsicchieri () hotmail com> To: <focus-ids () securityfocus com> Sent: Tuesday, October 15, 2002 2:56 PM Subject: How to keep sensors in sync using NTP?
Hi all, I´ve just installed Snort, MySQL and ACID on Redhat7.3 following the Snort Installation Manual, by Steven J. Scott (http://home.earthlink.net/~sjscott007/) In one of the sections (Network Time Protocol - NTP) he explain how to keep accurate time on the sensors (Snort) without having to manually set the clocks, using NTP: 1) Editing the /etc/ntp.conf file and changing the server entry to reflect my timeserver and comment out the entry starting with "fudge" ------ntp.conf------ server mytimeserver.com #fudge 127.127.1.0 stratum 10 -------------------- 2) # /etc/rc.d/init.d/ntpd start 3) # chkconfig ntpd on I´m using "ntp-4.1.1" and writing from "/usr/share/zoneinfo/America/Sao_Paulo" with "UTC=true" in /etc/sysconfig/clock file. Everything looks OK but the sensors stay 2 hours in advance. I already read the NTP manual but I still can´t figure out what is happen. Anyone could help please? Thanks, Bruno.
