I didn’t want to send this letter, but I’ve had enough of other people lying and not doing their jobs. It’s 2,000+ words of hatred and aggravation directed at a time honored service. I’m posting it here because I don’t think the USPS takes delivery seriously- I know they don’t because you can’t call them to tell them- their escalation method is, I swear on the life of my Mother- to SEND A LETTER. The call centers can’t do anything. You MUST send them a letter. I also don’t think that sending it Priority Mail Express, Insured w/ Signature Required will actually get delivered. Read on for more information. Updates will be posted at the bottom of the post.
This works for Linux and Mac command lines. It’s fast and easy to remember. Ready?
That’s it. It just returns your external IP. If you have curl under Windows it should work there too.
After making an image of a physical linux box (Dell hardware running CentOS), I converted the IMG file to a VDH file and after booting had many issue. One of which was the following error which caused all databases on the respective volume to fail because the volume was in read-only mode.
EXT3-fs error (device hda3) in start_transaction: Journal has aborted
Turns out, the system is telling me that it’s detected a file system/journal mismatch, and it can’t utilize the journal any longer. When this situation pops up, the file system gets mounted read-only. To fix the situation, I had to boot the system (now in the VM environment) in single user mode, dismount the volume and fix it.
I first started by removing the journal from the file system:
# tune2fs -O ^has_journal /dev/hda3
Then I tried to fsck it to correct any possible problems:
# e2fsck -p -f -v /dev/hda3
Unfortunately this lead me to another error: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options).
Ugh. fsck again….I had originally run it without the -f option and it found no errors, yet it refused to mount in read-write mode. So now running it sans the -p option, -f forcing it to check it anyway, seems to have helped- but this time I needed to be present to hit y to every single error. There were hundreds.
Once that finished I ran it again with the -y option to see if it picked up anything and it was clean!
Time to make a new journal which makes the partition an ext3 file system again:
# tune2fs -j /dev/hda3
I can now mount the partition as an ext3 partition:
# mount -t ext3 /dev/hda3 /mnt/fixed
After rebooting the system seems happy once again with no mounting errors. Quick and simple!
HP for the most part is a pain in the butt when it comes to finding parts for servers. BUT- I found a neat resource that lets you not only find parts but specific ones based on your server serial number. Total win.
It’s called the HP PartSurfer.
Finding a motherboard part number with just a serial number is stupid simple. Love it.
When you use your Windows 7 workstation for heavy network file copying the lan manager server tends to run out of memory. By making the following setting changes you can avoid this and enhance the file copy speeds.
Set the following registry key to ‘1′:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
and set the following registry key to ‘3′:
After making these changes, restart for them to take effect.
Additionally, this entry will likely be in your System event log:

The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.

Not sure where I found this but it’s a great email tag line:
Contents: 1 Hammer, 1 roll of Duct Tape.
Instructions: If it doesn”t move and you think it should, use the Hammer. If it does move and you think it shouldn’t, use the Duct Tape.
Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
The Big Bang Theory is a wealth of great quotes. It’s worth the time to watch!
