Take Your Rootshell Wherever You Go
posted in admin on 3 August 2012Working at a client's site I used to take my laptop with me in case I needed a rootshell on one of my servers. These times are gone, thanks to a little tool made by bitvise.com. Dr. Chris Brown pointed me in the right direction writing about this tool in his revealing and always well-written column in the Linux Format magazine. Essentially, the new tool called tunnelier, is a mature and stable ssh client for Windows. So I grabbed an empty memory stick and downloaded tunnelier. Running the exe file for the first time I decided to extract the software onto the memory key and put my encrypted ssh secret key on the stick too.
How To Secure Your Own Mailserver
posted in email on 8 Feb. 2013
Taking full control over your online business is the most important reason why you may decide to run your own server on the internet.
On your own server you can provide secure mailboxes for all your staff and you can make sure that all email accounts you use for your business are protected from unauthorized access. While you'll be able to control what's going in and out, you will also have to guard your mailserver against attempts to misuse the service you are providing for your staff and customers.
Fortunately, with the use of proper encryption methods, running a secure mail server is not only feasible but a great asset of your online business. I will describe all aspects of the set-up here in detail.
