If you are a long time follower of this blog, you know that I have shown you how to unlock the voice calling functionality of Huawei HSPA USB dongles.

If you are a Linux newbie and if you are used to Amazon EC2 or any other VPS control panels, Google Compute Engine terminal system will be confusing for you. Google Compute Engine uses Google’s own tool called gcutil tool to manage Compute Engine and its resources. Not only using it but configuring it is bit hard for the newbies. And you wont ever need that if you are just running one or few VMs and not going to unleash the total abilities of Compute Engine.

There is no way to set a root password’s on VM’s from the Console like you do on control panels like SolusVM but you can use SSH keys to access the terminal without ever touching gcutils. Here’s how to do it, Continue reading →

OpenVPN Auto installer

Leave a reply

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 →

Change your DSL modems default logins now or get hacked

Leave a reply

Are you using a DSL modem/router to connect to the internet? Mostly everyone I found haven’t changed the default user name and password which is used to login to the modems admin panel. Most modems comes with the default user/pass combination of admin/admin , admin/password. So what is the risk of not changing these logins?

Most of the older modems and around 20% of newer modems doesn’t have a firewall ( or disabled firewall option by default ) between the internet and the modem. So this means that anyone who knows your public IP can login to your routers admin panel and do potentially dangerous stuff. Including stealing your DSL services login names ( most common ) , opening up ports to give access to run malicious programs etc. Continue reading →
