Package Selection Options include: -f <file> Query package owning <file> Note: rpm -q — What does it do? One of the nice things about using RPM is that the packages you manage don't end up going into some kind of black hole. Nothing would be worse than to install, upgrade, and erase several different packages and not have a clue as to what's on your system. In fact, RPM's query function can help you get out of sticky situations like:You're poking around your system, and you come across a file that you just can't identify. Where did it come from? Your friend sends you a package file, and you have no idea what the package does, what it installs, or where it originally came from. You know that you installed XFree86 a couple months ago, but you don't know what version, and you can't find any documentation on it. The list could go on, but you get the idea. The rpm -q command is what you need. If you're the kind of person that doesn't like to have more options than you know what to do with, rpm -q might look imposing. But fear not. Once you have a handle on the basic structure of an RPM query, it'll be a piece of cake.

When I have a device that is acting up, I tend to run: ethtool ethX, check the Supported link modes, the Link partner advertised link modes and the actual speed and Duplex. If my Supported link mode is set low (say 10/Half for some reason) but my switch supports 1000baseT/Full then I'll use ethtool -s ethX to change my ethernet settings to 1000baseT/Full. Just about anything you see from: ethtool ethX, can be changed with ethtool -S ethX. In this case you would use the following:ethtool -S eth0 speed 1000 duplex full autoneg on

A: DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time.C: Key benefits and features of DTrace on Oracle Linux include:Designed to work on finding performance bottlenecks (C) Dynamically enables the kernel with a number of probe points, improving ability to service software Enables maximum resource utilization and application performance Fast and easy to use, even on complex systems with multiple layers of software D: Testers write tracing programs (also referred to as scripts) using the D programming language (not to be confused with other programming languages named "D"). The language, a subset of C, includes added functions and variables specific to tracing. D programs resemble awk programs in structure; they consist of a list of one or more probes (instrumentation points), and each probe is associated with an action. These probes are comparable to a pointcut in aspect-oriented programming.
