With tax season coming up I have been asked to set up a certain centralized tax service for a company. I won't mention the company nor the well known tax program involved as this post isn't about flaming a product but just to show you how cool commands in Linux can be used to solve, what would originally seem like, complicated problems.

Here's the scenario. The software runs on JBoss (a java app server) and it has log output. During client testing with fake social security numbers...

Ventrilo and RHEL/Fedora

Well I just set ventrilo up on my internal dev server. Just trying it out because I've heard other people talk about it and thought I would integrate it better with my system. I'm running Fedora 14 on my server but all of these scripts should work on Fedora 12/14 and RedHat EL 5/6. Untested on the new Fedora 16. Here's the service script.
Code:
#!/bin/bash

#For RHEL and Fedora-like operating systems

SELinux and sshd

So I've started using the new Fedora 16 on my main media server (previously F14) and decided to try something new this time. I've always set SELinux to permissive which is a bad idea normally for anything public (which this server isn't but I still want it). Anyway I believe I was testing something before I left for the holidays and ran
Code:
setenforce 0
which disables SELinux. I guess at some point it turned back on somehow and I was locked out of ssh. I dug through my logs (/var/log/messages,...

SELinux and Apache ProxyPass

Posted 12-07-2011 at 12:39 PM by sag47
Updated 08-05-2012 at 12:58 AM by sag47

Today I was having trouble getting a httpd ProxyPass and ProxyPassReverse to work. As a background I'm working in RedHat Enterprise Linux 6.1. It took me a while to figure out what was wrong (longer than it should have) and as it turns out it worked after I disabled SELinux. So my configs were correct in /etc/httpd/conf.d/* and it passed all config tests. I'm sure you don't want to read a whole post of talking so I'll just get right into the grit of the commands. For the rest of the explanation...

Stress testing a new hard drive...

You should always stress test a new harddrive when you buy it.

Some people say, "Just hook it up for a few months and keep unimportant data on it. If it breaks in that 1-3 month time then it will be good for 3 or 4 years."

While that metric is okay at best I prefer to take a more systematic approach to it. I want to fill the whole hard drive with random 1 and 0 over a constant and long period of time. I do that because you are stressing the hard drive out...
