I had a problem with an AWS Micro instance running WordPress on Ubuntu Linux where mysql would shut down randomly, at least once per week.
Looking in the error.log file I found the following error “fatal error: cannot allocate memory for the buffer pool” and “InnoDB: mmap(137363456 bytes) failed; errno 12“
I did some research and found that an Ubuntu micro instance doesn’t have a swap file configure due to it’s low memory capacity.
TO create a swap file, type the following commands:
- sudo dd if=/dev/zero of=/swapfile bs=1M count=1024
- sudo mkswap /swapfile
- sudo swapon /swapfile
- Add this line: /swapfile swap swap defaults 0 0 to /etc/fstab

I wanted to be able to work out how much internet bandwidth I was using via a Cisco router. To do this i needed to turn on NetFlow and then send that data to Solarwinds Network Traffic Analyzer.Here are the steps.
Log into your router.
Enter global configuration mode (configure terminal)
Enable NetFlow for each interface(in this case Dialer0) by typing: interface Dialer0
Then type: ip route-cache flow
then type (replacing xxx.xxx.xxx.xxx with the ip adderess the analyzer server) : ip flow-export destination xxx.xxx.xxx.xxx
Open up the Active Directory Module for Windows PowerShell from Administrative tools on your AD domain controller.
Type the following: Search-ADAccount -PasswordNeverExpires | FT Name,ObjectClass -A
And you will be returned a list of the accounts.
sudo apt-get install php5-curl
sudo service apache2 restart
I was getting this error on a Windows 2003 server with SQL 2005
Event ID 17182 “TDSSNIClient initialization failed with error 0x7e, status code 0×1″ and “TDSSNIClient initialization failed with error 0x7e, status code 0×60″
The fix for this is to disable the VIA protocol.
To do this, open up the SQL Server Configuration Manager, click on SQL Server 2005 Network Configuration , then click on Protocols for MSSQLSERVER and then right click on VIA and choose Disable.
You should then be able to start the MSSQLSERVER service.
To disable login acces to a user: sudo passwd -l USERNAME
To enable login acces to a user: sudo passwd -u USERNAME

Go to Run and then enter this:
A folder will open containing lots of ”.automaticDestinations-ms” files.
You can open these with notepad and edit them, or remove them to clear away broken links.
NOTE: removing the files will clear away all shortcuts from the Jump Lists.
Simply go to Run and enter this
C:\Users\%username%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
And you will have the folder with the shortcuts to pinned items.
