OpenVPN Auto installer

Auto installers are designed to make your life easy. Installing and configuring things like Nginx and OpenVPN can be hard for novices. You can use the Nginx Autoinstaller listed on my blog if you need that, but what about OpenVPN? OpenVPN-AS is free and comes with a great web based control panel, but the problem is that the free version is limited to 2 concurrent users. But that’s the way to go if you are fine with 2 user limit, You can view my OpenVPN-AS setup guide here.

If you don’t like the 2 user limit on OpenVPN-AS you can install regular OpenVPN but it requires little bit of work, it has no limits on users and you and your friends or clients can use the same VPN concurrently. I have found a great OpenVPN auto install script on github and I thought about sharing it with you. You can find it here installing it is very easy. See below Continue reading →

If you are a regular follower of this blog, you might remember that I have wrote about how you can get remote desktop running on Ubuntu VPS or Dedicated Server. And to connect it via VNC I have used Gtkvnc viewer in the past. Read about it here However Gtkvnc viewer had major drawbacks like, there is no option to save the server details, So it means that you have to enter the details of your remote desktop server every time when you want to connect to it.

Ubuntu 13.04 released and my thoughts

Leave a reply

Ubuntu 13.04 Raring Ringtail got released few days ago on April 25th. I have been using Ubuntu as server OS for past 3 years and as you might already know I have switched to Ubuntu from Windows as my primary work OS about 8 months ago and I don’t regret it. Until the release of 13.04 I had 12.10 wubi dual boot setup because that’s how I started using Ubuntu. Even though I had dual boot setup I didn’t used windows at all, I had it on my 128GB Samsung 830 SSD and since the space on my wubi installation was running out I have decided to wait for 13.04 release and do a clean installation of Ubuntu without any dual boot setup.

The minimum requirements to run linux kernel is mentioned as 2MB RAM and 80386 processor (32bit) on Linux documentation project. This 32bit requirement is addressed by emulating ARM processor inside the micro. And micro is overclocked to 24Mhz. Continue reading →

VPS connectivity and performance benchmark

Leave a reply

Easiest and best way to find the performance of your dedicated servers or VPS’s is to benchmark them. I have covered how to do a Geekbench test on your linux server here . But that doesn’t test for variables like bandwidth. I know that testing connectivity speeds is easy as running “wget”s against some test files. But I have found a great little script which does this very easily Continue reading →
