Friday, November 4th, 2011

A network power switch can provide network administrators and tech support personnel with an incredibly convenient tool for controlling power and reboot functions at off-site data centers and remote network equipment cabinets. In many cases, the remote reboot and power control functions provided by a network power switch can allow you to deal with power related problems with remote network elements without the expense and lost time of traveling to the network equipment site in person.


Upgrade Security on Secure Shell with a Few Easy Steps

Monday, January 17th, 2011

Here’s some food for thought for network administrators …

Secure Shell is nearly always put in place as a secure replacement for telnet. It’s default behavior for any administrator. But the problem is, out of the box, Secure Shell isn’t as secure as it can be.

WTI Out of Band Management products include Direct Connect capabilities, that allow you to initiate a Telnet, SSH or Raw Socket session with the Out of Band Management unit and then make an immediate connection to a serial port of your choice, without first being presented with the Out of Band Management unit’s command interface.

Monday, December 20th, 2010

Here’s a cool trick for Seahorse users …

Seahorse is a very powerful tool for the creation and managing of various keys. Seahorse is the default keyring manager for the GNOME desktop.

As you know, you can create secure shell keys that can be used for an even more secure ssh environment. I have shown how this is done via command line (see my article “Five handy secure shell tips and tricks“), but did you know that this can be taken care of using the Seahorse GUI? Let’s take a look and see how this is done.

But in the finance industry, the most important server console switch feature is always security and authentication.
