It Fixed it for me - eBox on Virtual Box

I came across an interesting Linux distribution I though I might try out called eBox.
From their website

eBox Platform can act as a Gateway, an Infrastructure Manager, a Unified Threat Manager, an Office Server, a Unified Communication Server or a combination of them. One single, easy-to-use platform to manage all your network services.
I didnt have any extra physical machines to run this on so I decided to try this one on Virtual Box as I am running some other test distros on my Vmware server. Anyway I downloaded the iso image and mounted it in my new Virtual Box virtual machine. The install ran fine without any issues however when the base install step completed it needed to reboot to start the actual eBox setup. Upon restart the virtual machine would not start and I was presented with the following error

this kernel requires the following features not present on the CPU: 0:6

As eBox is based on ubuntu linux I found the solution on the ubuntu forums.
In order for to get ebox running in Virtual box you must follow the below steps:

In VirtualBox. Right Click on the eBox virtual machine and choose settings. In the Settings window that pops up, General selection on the left, click the Advanced tab on the right. Enable PAE/NX is in the middle of the window in Extended Features.
Once I made the above change I restarted the virtual machine and it continued with the eBox set.

VMware Server - vmrun list command

This is a quick how to article on using some basic command line tools to administer VMware server 2 virtual machines running on a Linux system. In my case I am running Vmware Server on Centos 5.4 but I'm sure this will be very similar if not exactly the same on other versions of Linux.

Anyway here is the small problem I ran into. I wanted to get a list of running virtual machines on my centos server so I used the command

vmrun list

If memory serves me corretly this used to spit back a list of the running vms. However the above command now returns

Error: Malformed hostname parameter. For the given service provider, the hostname must be a URL, in the form https://:/sdk

The correct command that did work was

vmrun -h https://localhost:8333/sdk -u adminusername -p adminpassword list

The above command would then produce the following output.

Total running VMs: 1
[standard] XPPro/XPPro.vmx

The command above can be adjusted accordingly run other functions on the vm as well (start, stop, pause, etc...). Please see the full documentation on the website.

I not sure when the command changed (perhaps for better security in the latest vmware server software) but the above steps now get me to where I need to be.

Hope this helps someone else.

Samsung Omnia i910 CF03 update

As you may have already heard Samsung has released an update for the Samsung Omnia SCH-i910 Cell phone. The latest update is the CF03 and is available from the Samsung website.

There is a fairly straight forward install directions page located here. This page is for performing the upgrade on a Windows XP (32bit) system. There is also a version available for Vista (32bit)
At this time the 64 bit version is not available. ( or at least I couldn't find it).

A high level overview of the process is listed below.

  • Installation Of Microsoft ActiveSync 4.5
  • Backup Data from the SCH-i910 to the Computer Using ActiveSync 4.5
  • Downloading of the Software Upgrade to the Phone
  • Verification of the Phone's Software Version

As I already had ActiveSync 4.5 installed I moved on the next step.
After I backed up the data to my PC I downloaded the upgrade app. Be aware the app is about 125MB to download. The download is a zip file to you will need to unzip the file to run it.
Just double click the app and follow the on screen instructions. After the process completes successfully all user data and settings will be gone and will need to be set again. This includes any apps that you may have purchased separatly. For example I bought SPB Pocket Plus. After I ran the upgrade I needed to reinstall the app and reenter my serial number. So make sure that it is handy before the upgrade.

The whole upgrade to CF03 process took about 30 minutes and was fairly straight forward. I did encounter one small issue that I was able to overcome. After you backup your files and start the upgrade app it states that you should reset the phone (power cycle) and the upgrade will start automatically.
For me this did not happen. I had to reset the phone a second time. After the second reset the upgrade proceeded normally. Im not sure if this is a know issues but I was very cautious about resetting it again as I have read that it could render your phone useless.

Once the upgrade completed it rebooted the phone and came up to the first Windows Mobile set up wizard ( for the touch screen).

I have been restoring all of my data and settings but so far all seems to work well. There have been a few UI updates that are noticable including a better touch keyboard feel. The GPS receiver has also been unlocked for third party apps.

As the Samsung website states there is link to customer support if needed.

Now if I can only get Google Maps to connect to the GPS I will be all set.

Good Luck.

It Fixed It for Me - How to remove Antivirus System PRO

Antivirus System PRO is apparently a new rogue program that infects your pc then nags you about false infections in attempt to scam the user to purchase the software. Antivirus System PRO will nag the user with bogus pop ups claiming infections that are not really present. For example, I had a pc with this infection that was the network cable was removed from pc that continuously displayed a popup message that there was an attack underway from seemingly random ip addresses.

This infection is removed by using my favorite spyware removed program, Malwarebytes.
Here is how I removed this infection
  1. Boot the Pc into SAFE mode
  2. Login as the Admin user
  3. Install Malwarebytes if its not already installed ( I used a USB key to transfer the most recent installer to the infected pc) and update the definitions to the current database.
  4. Run a full scan on the infected pc
  5. Reboot once the scan is done
  6. Again login in safe mode as the Admin User
  7. Run a full scan again to ensure that the infections are gone.
  8. I then rebooted into normal mode and logged in as a regular user.
  9. I ran the scan again just to triple check. ( if there is more than one normal user repeat for each user)
  10. The Pc should now be clean

Hope this helps.

It Fixed it for me - How to hide the mysql information_schema database.

This is a quick post on how to hide the information_schema database from standard users.
In teaching a web design class I set up a few test student accounts on my mysql Linux database server for the class to play with. However when they logged in to phpmyadmin they could see their own database as well as the "information_schema" database. For security I wanted to hide the information_schema database from the users while they "play"

The solution I found was to add the following code to your file

$cfg['Servers'][$i]['hide_db'] = 'information_schema';

After the above change the users could only see the database that they were allowed to see when logged into phpmyadmin.

Hope this helps someone.

It Fixed it for me - VMware MUI blank page

I can't take credit for creating this fix but I thought it may be helpful to get the info out there again.
I recently installed VMware Server 2.0.2 on a new Centos 5.4 Linux server (32bit but it may work on 64bit as well) the install appeared to go smoothly but when I tried to go to the MUI (management user interface) all I received was a blank page.

I found a post over at that seemed to remedy the issue.
What I had to do was from a command line on the Centos 5.4 Server run:
(Note the below script may wrap on the screen.)
mkdir /usr/lib/vmware/lib/
cd /tmp
mkdir tmp
cd tmp
rpm2cpio glibc-2.5-34.i386.rpm |cpio -ivd
mv lib/ /usr/lib/vmware/lib/
rm -rf /tmp/tmp
service vmware restart
After I ran this mini script I then restared the VMware services and I was able to see the MUI web page again.

Apparently there is a problem with a particular library on Red Hat and CentOS systems.

As usual this may not be the only solution but "It Fixed It for me"

Product Review - PNY 4GB USB Flash Drive

Here is a small review of a USB Flash drive I just picked up.
I bought a PNY 4GB USB 2.0 Flash Drive Micro Swing Attache drive from Staples for $17.99

I havent been using it for long but so far I really like it. It has a push button on the side that make the USB connecter "flip out" from the side of the device. It comes in several different colors ( I picked Blue) so you can keep different drives for different purposed or even one for each family member. Another thing I liked about the drive is that it has a small hole in the end to attach it to a key ring. I seem to always leave mine on my desk but usually always have my keys.

I have installed almost 1GB of portable apps on it so far and have plenty of room for my other needed docs.

For only $17 you cant go wrong with this one. If you have one please let me know your opinion of it by posting a comment.

It Fixed it for me - Event ID 7031 - Source Service Control Manager

This past week I had a client contact me regarding a strange printing problem. It seems that when ever he rebooted or even tried to open up the Windows XP printers screen he would get a message that "The Print Spooler service terminated unexpectedly." If I looked in the Windows services applet the Print Spooler service was stopped. If I tried to start it, it would start but as soon as I tried to look at the installed printers or try to print from any application it would give me the same error again. In the Windows Event log I found many Event ID 7031 errors.
I did come across a windows kb article that sounded somewhat similar but it didn't help in my case.

The solution I found was fairly simple:

First I needed to stop the spooler service (which was already stopped and would not start ayway)

Second I opened up a Windows Explorer window and browsed to C:\WINDOWS\System32\spool\PRINTERS. I simply deleted all the files in this folder.

Once this was done I could start the print spooler service and everything worked again.
This worked for me on a Windows XP pro machine so I am not sure if it will work for Windows Vista or Windows 7. If anyone tries this on those operating systems please let me know if it worked by posting a comment. Apparently it had to do with an application that sent a print job to the spooler that got corrupted or was not in the correct format.

As usual this may not be the only way to remove the software but "It Fixed It for me"
