By default, HP’s ILO interfaces are set to DHCP.
Yes you could go into your router to see which DHCP lease it got, but here is a much more easy solution that you can use anywhere, even though you don’t have access to the router/DHCP server.
You don’t need much. What you need on your Linux computer for this to work is:
If someone would like to take pictures and screenshots of the process for me that I can put into the guide, that would be great. Since I do not have a running Windows computer at the moment I can’t make them myself. (post a comment and I will contact you). This line will be removed once I have the pictures i need.
Some guys a reddit.com requested that I made a quick guide on how to flash a LSI Megaraid M1015 SAS/SATA controller for pass-through firmware.
This guide will be on how to flash it for pass-through OR raid functions, since it’s the same method but with two different files.
I will supply you with the files needed as well.
You will need the following:
That’s all you need except for the raid controller itself and a computer/server to install it in!

Yesterday I decided to upgrade my two ESXi servers from ESXi 5.1 to ESXi 5.5 since the update came out some time ago.
The upgrade from ESXi 5.0 to ESXi 5.1 went great, without any problems. But this time, that is not the case.
My two ESXi servers are white boxes made of the following hardware:
The problem was the motherboard that ships with an onboard Realtek 8111E network adapter.
This problem has been verified to be the same with Realtek 8168 and Realtek 8169.
The reason for this, is that VMware removed the drivers from the new ESXi 5.5 iso.
In this post I will show you how to get ESXi 5.5 working with the Realtek network adapters.

Distributed file system between multiple servers is a thing I have planned for a long time, but I never got around to it because I first had to find the right filesystem for it.
After a lot of research, I found that GlusterFS was the right file system for me.
My plan was to use a distributed filesystem to share the content of my webservers to make sure all my webservers had the same content on their pages at all time and using some sort of high availability to make sure the content was always there.
To this I used a tool in Linux called Lsyncd before I set up my GlusterFS cluster, this worked well and did live syncing of all the servers using rsync. But there was one problem with it.
If I uploaded a lot of files (20+) to one webserver, and it started to sync to the other webserver before I was finished copying, the result would be that some of the files ended up corrupt, and this was a problem for me!
Here is the overview of the setup I am making, it’s not pretty but I’m sure it’s a lot more easy to explain the setup using a simple mspaint drawing than with text!
As you can see in the picture above, I have build this with high availability in mind, since I want my websites to always be up and running!

So you found an old D-link DP-101 or other printer server that you need to use, but don’t know what static IP address you gave it years ago?
The solution is simple.
This also on other D-link print server models, if you did this on models that are not listed below, please leave a comment so i can add them.
Verified to work with:
The D-link Dp-101 is a stable parallel to network print server, but it does not have the feature of a “Reset to default settings” hardware button anywhere. If you want to reset the device to default, or change the IP address without knowing what it is now, you have to do it with D-link’s tool, and it only works on 32Bit computers!
Here is how you do it, with link to the software

This is a quick post on how to configure the management IP address on a D-link switch. Mine was a DGS3324SR but i bet it’s the same on all D-link managed rack switches.

Update: I have not tested this on Windows 8, but it should work. If anyone does this on Windows 8 (i don’t have a Windows 8 machine laying around), please leave a comment to verify if it works or not.
Yes, this post is about Windows!
I had a problem yesterday, and thought I should post my solution since I had a hard time getting it to work and it might help others.
I have a D-link DGS-3324SR rack switch for my servers, and it had some random IP address on the configuration interface that I was not able to find, and I needed to get into the switch to configure some vlans.
I thought “That’s easy, just connect to the console port and thats it”, but then i came home to notice that none of my computers have a serial (RS323) port!
I then found a serial (RS323) to USB converter at work, the Belkin F5U103V and borrowed it for the day, but when i got home and plugged it into a Windows 7 64Bit laptop I noticed that there was no driver found for the device.

TEMPer v1.4 is a great little gadget.
I bought this of dx.com for under $10 with free shipping all the way to Denmark!
Here is a quick review of what i think about the device.

I have a small server room, with some rack servers, NAS’s, VMware ESXi’s and other fun stuff, but I had one problems.. in the summer it got really hot, and I had to open the window to let fresh air in, and the old out to lower the temperature again, but I never knew when it was too hot, so i had to drive by the server room once or twice a day to manually feel if it was too hot..
This was a problem, because sometimes I was not home, or sometimes I forgot, or just had no time to drive by to check the temp.
Having a temperature sensor in the room, from a freezer or something like that didn’t help me much, since I still had to drive by to check it manually.
So I had to make something I was able to get the room temperature from, over the internet/lan, and thats when I decided to make my network thermometer.
I looked for weeks on the internet for a good guide about this, but none of them worked. so I decided to write my own to help others with the same problem out.
How to make your own network thermometer, using open source software and a cheap USB temperature sensor!

Having your MySQL data on a separate partition is important because when your root partition fills up and no space is left, your system won’t be able to boot and might crash when running, you then have to boot from a recovery disk to remove files before you can boot on your normal system again.
This is critical for servers that you can’t allow to be down for an hour or two!
The solution is easy, you just move your MySQL data to a separate partition, and this problem won’t occur any longer, the only thing that happens when you run out of space, is that the MySQL can’t write any new data to the database, which is better than the entire system crashing and being unable to boot.
In this guide i will show you how to make the changes needed to get this problem resolved.
