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.

An out of band management ( solution can provide network administrators with a convenient, reliable means to communicate with remote network devices when communication via network is not available. Although out of band communication is a vital element in many remote network equipment management applications, in most cases, out of band management solutions rely on a dial-up modem connection between the administrator and the out of band management unit.

An out of band management solution provides an extremely convenient tool for network administrators who need to manage and troubleshoot remote network equipment sites. In most cases, out of band management relies on a secondary network to allow access to command functions on remote network elements in order to check unit status, diagnose problems and get remote network equipment up and running again. This obviously simplifies the process of dealing with problems at remote network sites … but what does an administrator do if a secondary network is unavailable or unfeasible?

Sometimes, it’s nice to have as many alternatives as possible; especially when you’re talking about a console server. When your network is down, a console server with an out of band management solution often provides the only way to access command functions on remote network devices, without a long, expensive trip to a remote network facility. With that in mind, it’s good to know that WTI console server products provide two different means for accessing command functions on remote network devices: via out of band network, or via dial-up modem.


Out of Band Management – An Essential Tool for Network Administrators

Wednesday, October 20th, 2010

To network administrators, the term “out of band management” can mean a number of different things, in some cases, it refers to a secondary, maintenance network that parallels the main network, and in other cases, it may refer to a dial-up/phone line connection to network devices. Generally speaking though, out of band management refers to a connection to a network device that comes from outside of the main user network.


Out of Band Management via Dial-Up

These days, when network administrators talk about “out of band management,” they’re usually talking about a serial console server, coupled with a secondary, maintenance network that works in parallel with the main network and serves to provide maintenance access when the main network is down. For the most part, that’s usually the case, but there are also cases where “out of band management” refers to a serial console server that can be accessed via a dial-up connection when network communication is not available.


Does Your Console Server Provide Adequate Out-of-Band Security?

Monday, September 13th, 2010

These days, it’s pretty hard to find a modern console server that doesn’t include several different levels of security and authentication for web access. But what if you need to contact your console server when the network is down? Does your console server provide adequate security for out-of-band, dial-up access too?

Like most console server products on the market today, WTI console servers include a robust assortment of security and authentication features, but WTI console servers also go a step further by including password protected, dial-back security for out of band access. This means that even when network communication is not available, you can still dial into a WTI console server without compromising security.
