Recently I decided to use Amazon AWS EC2 platform to host systems in the Cloud. As operating system I needed is Linux I quickly deployed Amazon Linux AMI, which is quick and simple to do.
Once instance was created I downloaded key pair. Now it came down to connecting to my virtual machine in the cloud.My SSH client of choice is SecureCRT. Let’s see how to configure session parameters in SecureCRT in order to connect to Amazon Linux AMI instance hosted on EC2 platform.

Usually I tend to create DHCP server on Windows Server. However, sometimes there is no server on site. Only what I have are network devices, workstations and voip phones. In those cases I used to create DHCP server on switches. As environment I operate in contains mainly Cisco devices, each location has at least one or more Cisco Catalyst switches (2960 or 3560) it is possible to provide DHCP service using IOS features. Example contains DHCP configuration for network with different VLANs for data, voice and printers.
Below is short description and set of commands demonstrating how to setup:
- DHCP scopes
- Define DHCP helper on the interface
- Check status of DHCP assignments

So, I was wondering how to access my PlayBook using SSH. It would be really convinient to access it from laptop, browse files, etc. I did poke around on Internet and finally identified solution how to SSH to PlayBook 🙂 For now only as a normal user and working towards getting root access (I guess Dingleberry will be helpful at some stage) 🙂
For now let’s have a look into details of accessing PlayBook via SSH. for that I will use:
- BlackBerry Tablet SDK 2.0.0 – available for free on BlackBerry web page here. There might be newer version available by now.
- PuTTY – I guess most popular free terminal emulator for SSH, Telnet and Serial connections, available here. From that package PuTTY.exe and PuTTYgen.exe will be required.
