Posted on by

Yet another scam that goes around. This time it`s an attempt to brand owners to “register” their brands in China before “some company steals it”. And as usually, just to ignore.

(Letter to the President or Brand Owner, thanks)

Dear Sir/Madam,

We are the department of Asian Domain Registration Service in China. I have something to confirm with you. We formally received an application on April 22, 2013 that a company which self-styled “YaZi Int’l Company” were applying to register “<brand>” as their Brand Name and some domain names through our firm.

Now we are handling this registration, and after our initial checking, we found the name were similar to your company’s, so we need to check with you whether your company has authorized that company to register these names. If you authorized this, we will finish the registration at once. If you did not authorize, please let us know within 7 workdays, so that we will handle this issue better. After the deadline we will unconditionally finish the registration for “YaZi Int’l Company”. Looking forward to your prompt reply.

If you want a shortcut to some of your favorite websites from the home screen, you first have to add those websites as bookmarks. In Chrome i do this by pressing menu, then selecting the star icon.

Afterwards, go back to the home screen, select menu, select “add apps and widgets”, then add the bookmark widget. You will then get a list of your bookmarks which you can add to your home screen.

Adding SSH support to PHP on Ubuntu

I have previously written a post on how to add SSH support to PHP, but that post is old, and it has now become even easier to get it up and running. And therefore making it much easier to auto upgrade WordPress via SSH. (automatic, yay!)

As root, do the following:

1: apt-get install libssh2-1-dev libssh2-php

2: Check that is installed: php -m |grep ssh2

3: Restart apache: service apache2 restart

And you should now have SSH support in PHP.

Outdated entry in the DNS cache error when using Remote Desktop

Posted on by

You may sometimes get error messages about outdated entries in the DNS cache, when you are using remote desktop. (The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name.)

The first thing you should do, is to make sure that the clock is correct on these nodes:
1: The client machine
2: The remote machine you are connecting to
3: And if used, the domain controller(s).

And of course, make sure that you don’t have any invalid dns cache. clear the dns cache by doing this in cmd: ipconfig /flushdns.

If it is still an issue, another work around can be found here: http://extremeengineers.net/?p=126 (although, you should fix the problem and not the symptom)

 

Enabling SSH installation of Data Protector clients

Posted on by

Just a quick how-to- make sure that you can install new Data Protector clients using SSH.

All this is done FROM the Linux the installation server, using the root user.

First of all, you have to copy the .omnirc-file if you have not done it before.
cp /opt/omni/.omnirc.TMPL /opt/omni/.omnirc

Then, edit the .omnirc file in /opt/omnic/ and make sure that OB2_SSH_ENABLED is set to “1″.

Then you need to make sure that the installation server can SSH to the client(s) without being asked for a password. If you do not have a SSH-key, you can generate one by running ssh-keygen.

Now copy your public key to the client(s) that you are going to install Data Protector on, by running ssh-copy-id root@<client>. Test it afterwards by SSHing to the client(s), if you do not get asked by a password, you are good to go!

PS: You have to SSH to the client at least once, as you will be asked to confirm the client certificate the first time.

KVM: Optimizing performance on virtual machines (VM`s)

Posted on by

After having set up quite a few VM`s in my career, i have picked up a couple of tips on how to get the most power out of your VM`s:

Get new/correct drivers for your VM`s
Remember to make sure that you have all the correct drivers, this is at least important for IO(Disk) and Network devices. Windows has many devices that will work with basic Microsoft drivers, but that does not mean that the performance magically gets awesome. After making sure that the correct drivers were in place, i managed to go from ~900Mbit to 9.9Gbit on a 10gbit-network between a Linux (Red Hat) and Windows 2k8 server. (tested with iperf which exists for both Windows and Linux)

Turn off Power saving options in BIOS / Hardware
More or less all servers, either they being brick servers, home servers or blade servers, have BIOS settings that enables or disables power saving mode. I know from experience that at least all HP blades comes with power saving enabled per default. Turn off this to make sure that your VM`s gets the performance they expect to get. (I have had VM`s simply be sluggish with this feature turned on, turning it off made CPU-performance get normal)

Turn off CPU throttling on the VM host machine
I have also had issues with slow VM`s even when the power options was fixed in BIOS. I then realized that some Linux distributions (Ubuntu) have a default CPU scheduler that throttles down the CPU when it is not needed. After making sure that the host did NOT do this, the VM`s finally started acting as they should. Check out your Linux distributions guides on how to change this.

 

Any other tips i should add to the list? Feel free to add a comment below! :)

HP iLO: Controller firmware revision 2.07.00 Embedded media manager failed initialization

Posted on by

I just received a notice during boot of a HP G8 server regarding iLO issues: “iLO 4 has detected a self test error. For details consult the iLO 4 server and iLO 4 diagnostics page”.

Went into the iLO diagnostics page (in the Blade Center admin) and found the error message “Controller firmware revision 2.07.00 Embedded media manager failed initialization”. Google does not give too much info regarding this, so it is a bit hard to see what is going on regarding this. I tried to restart both the blade and the iLO itself, but the error did not go away.

I had to contact HP regarding this, and the conclusion(after both having to try a firmware upgrade and firmware re install), was that it was a hardware error on the iLO storage, so HP had to replace the whole motherboard for that server.

How to install Munin-node on RHEL6

Posted on by

Munin-node is not available per default on RHEL6 servers. But luckily, somebody has made a mirror which contains many nice applications, including the munin packages we want.

rpm -Uvh http://ftp.uninett.no/linux/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum install perl-XML-SAX

yum install munin-node

And voila! :)

perl-XML-SAX has to be installed first due to dependency issues.
