  5. In the environment I work in we have multiple firewalls in a path so the likely of your traffic being blocked is high. Most of us use to troubleshoot using telnet which has many many flaws and not a great method of testing but it was all we had. Here is an example of testing using telnet telnet 10.11.24.11:80 telnet: 10.11.24.11:80: Name or service not known 10.11.24.11:80: Unknown host The telnet results don't really give you anything to tell you if its successful or not. Then I discovered at a young age the power of nmap (which is probably why it was quickly blocked in mos
  6. Yea yea, I know this title is very generic and yes we all like to bag on Microsoft but this is more of a very high level side by side with Microsofts product, Windows. Why is Wordpress like Windows? They both are slow over time. The more you add the slower it gets. The more software, plugins you add the slower it gets. They are both very insecure and require a separate security package. Here is my experience with Wordpress since this is all just a learning experiment. I built a community on Joomla using Kunena as a forum and EasyBlog as my blog and eDocman as my File M
  7. Sometimes your linux box has been running for such a long time you may have forgotten what the heck you are running. The quickest and easiest way to identify what you have is run the following command lsb_release -a example: If that doesn't work for one reason or another try this command instead cat /etc/*-release example: You may also want to know what kernel version you are running uname -a or uname -mrs example: Linux = Kernel name 3.2.0-35-generic-pae = Kernel version number i686 = Machine hardware name Finally you can see what kernel and gcc versio
  8. There are several commands to show how much memory is being used or how much is free or what process is taking how much memory. What command can you run to show the percentage of what is free? Would be helpful to compare to reporting tools to see if they match.
  9. NAME vmstat - Report virtual memory statistics SYNOPSIS vmstat [-a] [-n] [delay [ count]] vmstat [-f] [-s] [-m] vmstat [-S unit] vmstat [-d] vmstat [-p disk partition] vmstat [-V] DESCRIPTION vmstat reports information about processes, memory, paging, block IO, traps, and cpu activity. The first report produced gives averages since the last reboot. Addi- tional reports give information on a sampling period of length delay. The process and memory reports are instantaneous in either case.
  10. Sometimes its helpful to know what ports on your Mac are in LISTENING status. So here are a few commands that I found helpful in my quest to find what ports are open. $ netstat -atp tcp | grep -i "listen" tcp4 0 0 *.irdmi *.* LISTEN tcp4 0 0 localhost.49155 *.* LISTEN tcp4 0 0 localhost.49154 *.* LISTEN tcp4 0 0 localhost.49153 *.* LISTEN tcp4 0 0 localhost.49152 *.* LISTEN tcp4 0 0
  11. We may deploy several servers and we need an easy quick way to see if they are now responding I found fping to work best Throw all your IP's in a text file (for example pinglist.txt) and run it sudo fping -a -r 0 -f pinglist.txt
  12. On my Ubuntu Installation I found the installation at ls -l /usr/local/nagios/etc/ -rw-rw-r-- 1 nagios nagios 12270 Aug 4 07:09 cgi.cfg -rw-rw-r-- 1 nagios nagios 12270 Aug 3 15:05 cgi.cfg~ -rw-r--r-- 1 root root 50 Aug 3 15:07 htpasswd.users -rw-rw-r-- 1 nagios nagios 44904 Nov 2 08:22 nagios.cfg -rw-rw-r-- 1 nagios nagios 44833 Aug 4 06:58 nagios.cfg~ drwxrwxr-x 2 nagios nagios 4096 Nov 2 08:44 objects -rw-rw---- 1 nagios nagios 1315 Aug 4 07:09 resource.cfg -rw-rw---- 1 nagios nagios 1315 Aug 3 15:05 resource.cfg~ drwxr-xr-x 2 root root 4096 Nov 2 09:42 servers
  13. It helps, sometimes, to know what the last commands issued from a user on a Linux box was. I found troubleshooting this is helpful or to to help learning and it's just sometimes good to know. The easiest way I found is to issue the following command to identify what commands have been issued by a certain user on your linux operating system sudo vim /home/USER_YOU_WANT_TO_VIEW/.bash_history
  14. There comes a time that the DNS server(s) do not have the name to address resolution you need so just add it to your local hosts file. Mac OS X 10.2 or later Edit the /private/etc/hosts file. For more information on how to use the hosts file, open Terminal and type: man hosts Note: Editing this file requires root privileges. I suggest typing while in Terminal sudo nano /private/etc/hosts It may be a good idea to flush the DNS Cache that is running by then typing the following after you save the hosts file dscacheutil -flushcache
  15. Switching operating systems is a scary and can be exciting adventure. It can also be a major pain in the butt. I am not author of any book but hope I can help fill in some blanks. If you want a recommendation on a book, for beginners I strongly recommend a book called Teach Yourself VISUALLY Mac OS X Leopard It has proven itself to people of all ages on getting up and going with there move from Windows to Mac. Here are some basic things you may or may not know. Open Applications... In Windows you click the Start button - Click on Programs - Select Your Application In Mac OS X you click
  16. I am curious as to what I should do when I can not click on FInder (it just makes a sound everything I click on it like something is in the background waiting for me to answer it but I can't seem to find anything). I can not open a new window and I'm not able to click on the apple to do a restart. Someone said to open terminal and type something like: sudo -h shutdown now but i can't get to Terminal. You could click on spotlight and type Terminal and it will find it for you at which time you could just double-click on. As far as shutting down or restarting your system you could do either wi
  17. One way to store or group files on a Mac is to create a Disk Image. A Disk Image is a file which has the properties of a separate hard drive or CD. It has a size limit and options for encryption to keep your files safe and secure. This how-to will work with Mac OS X. Steps Create a New Folder and place the files you would like in your disk image into this new folder. Right click (or CTRL-Click) the folder and select "Get Info" and note the size of it's contents. Open Disk Utility (Applications > Utilities > Disk Utility) Click the "New Image" icon to create a new dis
  18. Your bad kitty will run faster and smoother after it sheds a few gigabytes. A slimmer cat is a faster cat, and we'll bet dimes to DIMMs that you can shed several gigabytes from your Mac's hard drive without missing them. If you installed the default Mac OS10.4, for example, you've got 1GB of foreign language translation support, 2.1GB of printer drivers, and 9.9GB of bundled software. Once you've removed the biggest offenders post facto by following the steps below, take an hour to browse your hard drive for such junk as sample or stock images in Photoshop and sample songs in GarageBand (they
  19. Tweak processor priorities and RAM usage where available Mac OS X is a masterfully multithreaded system with the ability to run and manage hundreds of tasks simultaneously, including tasks that you've initiated (a Final Cut Pro render, a Photoshop filter, a spell-check in Word -- anything) as well as oodles of background daemons, enless Spotlight indexing, and other noise. It's your Mac, so you get to decide which apps get processor priority and when -- it's known as niceness in the Unix world. Make iMovie nicer as it chews on your epic film while you write your acceptance speech in Word, or
  20. The Mac is rightfully revered for the beauty, power, and simplicity of its graphical user interface. Indeed, it was the release of the first Macintosh that brough the concept of pointing and clicking to the average computer user. But in addition to the point-and-click ease of the OS X Finder, your Mac sports on of the most powerful command-line interfaces on the planet: the Terminal. Mac OS X comes with hunderds of Unix programs - and you can get them all through the Terminal. As much as we love the ease of the GUI, the power of the Terminal is hard to beat. It allows you to do many things fas
