		<description><![CDATA[One nifty feature that recently made it&#8217;s way into OpenBSD is the ability to remotely update packages with the pkg_add utility. This is accomplished by adding the URL of a remote repository to the PKG_PATH variable, and then running pkg_add with the &#8220;-u&#8221; (update packages) and optional &#8220;-v&#8221; (verbose output) and &#8220;-i&#8221; (interactice installation) options: [...]]]></description>

		<description><![CDATA[Each and every operating systemI support has a different utility to report on swap usage. On my Soalris hosts, I use the swap and vmstat utilities to check utilization: $ swap -s total: 36176k bytes allocated + 4672k reserved = 40848k used, 1189004k available On Linux hosts, I use teh free and top utilities: $ [...]]]></description>

		<description><![CDATA[I recently had to manually add a few users to /etc/passwd and /etc/master.passwd on an OpenBSD 3.9 server. After I added the entries, the accounts were still unable to login. I started poking around with ktrace, and noticed that during a normal account creation session the files /etc/pwd.db and /etc/spwd.db were modified: $ ls -la [...]]]></description>

		<description><![CDATA[I manage a fair number of servers, and use several tools to monitor the health of my systems. One such tool is logsentry (formerly known as logcheck), which is a shell script that can be used to monitor logfiles for anomalies. Logsentry consists of a single shell script and one or more violation files, and [...]]]></description>

		<description><![CDATA[While persuing the OpenBSD ports collection a few weeks ago, I came across the ifstat utility. This nifty utility allows you to view bandwidth totals for each interface in a server, and at specific intervals. Here is a sample run showing the bandwidth in and out of the sis0 and sis1 Ethernet interfaces, and the [...]]]></description>

		<description><![CDATA[OpenBSD has a number of nifty utilities, and I happened to come across the systat(1) utility this weekend while looking for an executable in /usr/bin. Systat prints out performance data in an ncurses display, and can be used to view CPU saturation, I/O statistics, swap utilization, netstat data, and MBUF and network interface utilization. The [...]]]></description>

		<description><![CDATA[I have performed a number of OpenBSD installations in the past, and have always used the installer to set the timezone. One system that I recently built didn&#8217;t have a timezone set, which required me to run the zic(8) utility manually to change the timezone on the system. To set the servers timezone to Eastern [...]]]></description>
