Netflix has been down for several hours (November 27, 2011)

I believe Netflix is currently down ... it has been down since 5pm. At first, I thought I forgot my password, then when I clicked the "Forgot password" link, it sent me an e-mail with a link that took me back to this page again. I called the hotline +1 (877) 499-4427 and they said they are currently experiencing "problems with website and video streaming". Oh well.

How to install CentOS 6 from a USB drive with UNetbootin

I believe I'm one of the poor souls who tried to install CentOS 6 64-bit on a laptop with no DVD drive with UNetbootin. I need a full Linux test environment as I'm testing the directory server and a few control panel software and its integration with my Baby Gekko CMS. I tried putting the 4Gb ISO onto a flash drive along with the 4GB image that was created. Then as I was going to mount it, I couldn't go to tty2 since Anaconda installer hasn't given me a prompt yet. I got this error:
So I finally used the CentOS-6.0-x86_64-netinstall.iso with UNetbootin, then extracted the 4GB ISO disc 1 and 2 into a newly created directory in my local EasyPHP development server. I tried again and things are finally looking good, I finally got the graphical installer to show up. It was saying

Then I got this cripting error

Unable to read package metadata. This may be due to a missing repodata directory ... and there was this file ffb0e227e2cdd8a2b3609b65d7f38f6c1e756b437405b2918d6d36ebe59a0cb4 that was in the repodata dirtectory that couldn't be read or something like that.

I was in disbelief, so I tried going to the FTP site and looked up went to /pub/centos/6.0/os/x86_64/repodata and apparently the files were different than the one in the ISO. Then I deleted all of those from the repodata directory and replaced it with this one. Voila - my CentOS 6 is finally installed on my Dell Vostro V131!

Funniest Race Start Fail Ever!

This is definitely the funniest race start fail ever! LOL

 

Simple Bash Script to use OS X 10.4 as a firewall

There was an unused Apple desktop machine running OS X 10.4 sitting around, so I decided to use it as a storage for our company's firewall log. The current log is then rotated and saved in /private/var/log/archived. Here's the script:

#!/bin/bash
echo Stopping Syslog...
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist
sleep 1

echo ""
printf %s "Rotating log files:"
cd /var/log
for i in edmonton.log; do
    if [ -f "${i}" ]; then
        printf %s " ${i}"
        if [ -x /usr/bin/gzip ]; then gzext=".gz"; else gzext=""; fi
        if [ -f "${i}.6${gzext}" ]; then mv -f "${i}.6${gzext}" "${i}.7${gzext}"; fi
        if [ -f "${i}.5${gzext}" ]; then mv -f "${i}.5${gzext}" "${i}.6${gzext}"; fi
        if [ -f "${i}.4${gzext}" ]; then mv -f "${i}.4${gzext}" "${i}.5${gzext}"; fi
        if [ -f "${i}.3${gzext}" ]; then mv -f "${i}.3${gzext}" "${i}.4${gzext}"; fi
        if [ -f "${i}.2${gzext}" ]; then mv -f "${i}.2${gzext}" "${i}.3${gzext}"; fi

        if [ -f "${i}.0${gzext}" ]; then mv -f "${i}.0${gzext}" "${i}.1${gzext}"; fi
        if [ -f "${i}" ]; then
              touch "${i}.$$" && chmod 640 "${i}.$$" && chown root:admin "${i}.$$"
              mv -f "${i}" "${i}.0" && mv "${i}.$$" "${i}" && if [ -x /usr/bin/gzip ]; then
                gzip -9 "${i}.0"; fi

if [ -f /var/run/syslog.pid ]; then kill -HUP $(cat /var/run/syslog.pid | head -1); fi
echo ""

for i in montreal.log; do

        printf %s " ${i}"

sudo rm -f /var/log/montreal.log
sudo touch /var/log/montreal.log
sudo chgrp -v admin /var/log/montreal.log
sudo chmod -v go+w /var/log/montreal.log


sudo launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist

Then, I also added the following to /etc/syslog.conf

local4.*                        /var/log/montreal.log
local6.*                        /var/log/edmonton.log
local0.*                        /var/log/toronto.log

That's it!
