Additional Security for Dial-Up, Out-of-Band Access to Console Servers

Monday, January 9th, 2012

Although there are plenty of different security and authentication options available for IP communication with a console server, security and authentication options are much more limited for those who need to establish a dial-up out-of-band connection with a console server. Popular authentication protocols such as LDAP, Kerberos and TACACS+ work fine when communicating via IP, but at present, there are few alternatives for authenticating dial-up out-of-band communication.

Secure Communication with a Console Server that Supports SSHv2 Encryption

Friday, December 16th, 2011

A console server can provide network administrators with many convenient tools that simplify the task of managing network elements located at off-site data centers and remote equipment racks. When a device at a distant network equipment site suddenly crashes and takes your network down with it, a console server allows out of band access to console port command functions on the malfunctioning device, and often eliminates the need for an expensive service call to the remote network site that would otherwise be required in order to address the problem in person.

Out of Band Management via Console Server

Wednesday, November 9th, 2011

Out of band management is a vital capability for any network application that includes communication with remote network equipment, such as is often found at off-site data centers and in distant network equipment racks. When normal network communication with remote network devices is interrupted or not available, an out of band management solution provides an alternative avenue by which network administrators can communicate with remote network equipment in order to restore normal network communication.

IP Address Filtering – A Versatile Security Feature for Console Servers

Thursday, September 1st, 2011

When used properly, a console server can provide network administrators with a broad array of powerful tools that can be used to manage remote network elements, monitor conditions and events at remote network equipment sites and access console port command functions on remote network equipment. As is often the case though, these powerful tools also have a harmful potential if they are available for access by the wrong people. With this in mind, it’s easy to see how important security and authentication measures are to any console server product, and that in many cases, the more layers of security that are available to protect the console server, the better.

The Invalid Access Alarm – An Additional Layer of Console Server Security

Thursday, July 14th, 2011

Given the important role that a console server (http://www.wti.com/c-4-console-server.aspx) plays in out of band management, and the powerful command functions that can be accessed using a console server, it’s fairly obvious that security is an extremely important consideration for any console server application. Since a console server provides remote access to console port command functions on important network elements, it’s absolutely vital that the console server includes adequate security and authentication measures to protect sensitive command functions from unauthorized access.

A WTI Console Server with a Temperature Alarm Can Save Your Bacon

Thursday, June 23rd, 2011

Recently, our sales staff was meeting with an existing customer in order to discuss upcoming features that we intend to add to our console server products. In the course of the discussion, our sales people mentioned the over temperature alarm on our console server and remote power control products. Immediately after the words “temperature alarm” left his mouth, a brief wave of nervous laughter rippled across the room. As it turned out, the customer was already familiar with the over temperature alarms on our console server products; in fact, the temperature alarm on a WTI console server had saved their data center from going up in smoke just a few days before.

Console Servers Make It Easier to Deal with Problems at Remote Network Equipment Racks

Friday, June 10th, 2011

When a minor problem with network element brings down your main network, often all it takes to correct the situation is a few diagnostic and troubleshooting commands issued via the console port on the device that caused the problem. If the troublesome network element is located nearby, then it’s no problem to simply walk over to the device, connect to a console port and start issuing commands, but if the device that brought the network down is located miles away, then even a minor problem can halt network communication for hours while a service team travels to the remote site to deal with the problem in person. The best way to avoid network shutdowns caused by minor flukes at remote network equipment sites, is to implement an out of band management solution that includes a console server unit at the remote site.

Console Servers Provide the Ideal Solution for Remote Network Equipment Management

Friday, May 27th, 2011

The biggest problem with managing remote network equipment sites is fairly obvious; due to the “remote” nature of these sites, it’s usually pretty difficult for an administrator to know exactly what’s going on at a remote site and if anything does go wrong, then the only way to fix it is an expensive, time consuming service call to a site that might be located in a whole different time zone. Remote site management would be easy if you could permanently station a tech support team on-site 24-7, but who’s got the budget for that these days? In cases like this, a console server unit, intelligently deployed at a remote site can often accomplish the same thing as on-site personnel … at a fraction of the cost and also faster and more efficiently than a service call or truck roll.

Callback Security – An Important Feature for Modem-Based Console Server Applications

Friday, May 13th, 2011

When managing network devices at extremely remote installation sites, it’s not always possible to establish a connection with a console server unit via network cable. In cases like this, network administrators often rely on an old fashioned dial-up modem connection in order to communicate with the console server and other devices at the remote site. Although dial-up is obviously slower than a network connection, it serves well for administrators who need to check status or perform troubleshooting functions at these remote sites.
