Today I had to run a script on a 64Bit server, but was met with the following error:
/lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
The /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory error will happen only on 64 bit systems, the cause is the that 32 bit libraries are missing from the system and the script/program needs them, so it can’t run.
Have you ever been in the saturation that your Linux server is using a lot of network bandwidth, but it’s a guesswork to find the process using it all?
I just stumbled upon this tool, it’s not a new tools, but it’s extremely useful!
Let’s say you have a server running apache, mysql, ftp, btsync and a lot of other network services. and somehow that server is using up 100Mbit constantly. You want to find out what it is but only got tools like iftop, atop, iptraf and others which are all great tools, but they only show which connections are using the network bandwidth.

Are you like me, who want to listen to music while you work? But then your boss comes over and you quickly have to pause it? Or maybe you just want some key bindings on your linux workstation to make life a lot easier, then look no further! xbindkeys is the solution, and I will show you how in this post! it’s really easy to configure and extremely helpful.
In my example, I will use it to pause/unpause my music when i press CTRL+space no matter what desktop I’m on and even if I’m not in the terminal where MOC (the music player I use) is running.
xbindkeys is the name of the only package you need for this. It should be in the official repository for your distro. Install examples below:
apt-get install xbindkeys
pacman -S xbindkeys
yum install xbindkeys
This might be basics for some, but it’s a good thing to have bookmarked for the day you might need it. It helped me a lot.
The answer is really simple. I guess you formatted the drive using “fdisk” which use a ms-dos partition table.
MS-dos partition table (MBR) is 32 bit, and thereby it can’t handle anything above 2 TeraBytes
To fully use your 2+TB harddrive, you have to use a partition table that supports it. We now know that the MS-DOS partition table (MBR) does not, so what should you use instead? GPT.
GPT supports up to 9.4 ZB (ZetaByte). That’s 9895604649984 GB (GigaByte)!. It’s pretty safe to say, that you will not hit this limit in the near future.

I needed this to do some testing with a load problem I had. One of our server would spike in load for a minute or two, but at random times.
I needed to see what was generating these spikes, but did not want to sit around waiting for it to happen and being ready to hit enter on the commands i needed to run when the load was spiking. So I made this simple little script that you can edit to your needs.
It’s a bash script, and requires the package “bc” to be installed (install it using your package manager if you don’t already have it installed.)
I have tested the script on CentOS and Debian.
I have tried commenting everything in the script as good as possible, but if you have any changes feel free to post a comment.
Chromium is the open source version of Google Chrome.
There are some none-open source stuff in it that has been left out, a good example is the Chrome in-browser PDF viewer.
I needed this back, since I like it. so I did some googling around. I found lots a lots of posts, and none of them worked. But when I finally got it working, I decided to make this post hoping it will help others like me!
So this will be a short post on how to enable the in-browser PDF viewer in Chromium.
I think we all have been in the situation before, you have some scanned documents in JPG or PNG format that you need to convert into a PDF file.
There are many solutions for this on the internet, including free sites that just does it for you if you upload your images, but they almost always put some kind of watermark on the pages if you don’t pay them.
There are also a bunch of Windows applications that do this, but they are often complicated or full of ads.
This guide show you a free solution on Linux, that just works, is fast, and does not add any crap to the PDF.
