bsdtalk138 - Central Syslog

News:DesktopBSD 1.6 and FreeBSD 6.3 released.Setting up a central syslog server.If you are concerned about the security of your logs, use a dedicated machine and lock it down.Keep clocks in sync.You may need to change log rotation schedule in /etc/newsyslog.conf. You can rotate based in size and/or time. This can be as much a policy decision as a hardware decision.On central log host, change syslogd flags to listen to network. Each BSD does this differently, so check the man pages. Also, check out the -n flag for busy environments.Make sure host firewall allows syslog traffic through.Be careful to limit syslog traffic to just the trusted network or hosts. FreeBSD man page refers to syslogd as a "remote disk filling service".For heavy logging environments, it is important to have a dedicated network. A down syslogd server can create a lot of "ARP who-has" broadcasts.Most network devices such as printers and commercial firewalls support sending to a central syslog server. Take a look at "Snare" for Windows hosts.To send messages from a Unix host, specify the host name prepended with @ instead of a file for logging in /etc/syslog.conf. For example, change /var/log/xferlog to @loghost.mydomain.biz. You can also copy and edit the line to have it log to both a local file and a remote host.File Info: 7Min, 3MBOgg Link:https://archive.org/download/bsdtalk138/bsdtalk138.ogg
