A Console Server with Reverse SSH Capabilities Provides Additional Options for Out-of-Band Communication

Friday, May 1st, 2015

In most out-of-band management applications, a console server is connected to a secondary network, cellular router or wireless router and deployed at a remote site in order to allow remote access to console port command functions when primary network communication is not available. This works well in most cases, but if out-of-band access via both Ethernet and console port is required, a console server that supports reverse SSH connections can be used in place of a basic console server.

Communicating with Devices on an Isolated LAN via Reverse SSH

Tuesday, April 28th, 2015

Isolated LANs are often found in applications where either the remote nature of the site makes contact via outside network impractical and in applications where an outside network connection to the LAN might jeopardize network security. In cases like this, one of the few options for outside maintenance access to devices on the isolated LAN is often a console server that supports both dial-up access and the ability to create reverse SSH connections.

A Dual WAN Console Server Provides More Alternatives for Out-of-Band Management

Thursday, March 19th, 2015

When managing network elements in oil and gas applications, a Dual WAN Console Server can provide out-of-band communication options that usually aren’t possible with a traditional console server that only includes a single Ethernet port. In most cases, console servers with a single Ethernet port are designed primarily to allow communication via network and in some cases, dial-up. The presence of an additional Ethernet Port on Dual Wan Console Servers allows for connection to a secondary network and also simplifies the challenge of adding out-of-band access via 3G/4G/LTE cellular broadband or satellite broadband.

A Console Server Provides Out-of-Band Access to Remote Network Elements

Friday, August 9th, 2013

When you need to communicate with an unresponsive network element at a remote equipment site, there are basically two choices: you can either travel to the remote site in person, or you can use a console sever to establish an out-of-band connection to the problematic network device. When direct communication with a malfunctioning device is not possible, a console server provides a secondary, out-of-band means to access console port command functions on a remote device.

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 – The Fastest Way to Correct Problems with Remote Network Devices

Tuesday, October 12th, 2010

Computer networks offer an extremely practical and convenient means to allow many different users to access commonly used functions such as email, inventory programs, file servers and etc. But unfortunately, a network is only as strong as it’s weakest link. This means that if a firewall or a switch crashes, then all across your organization, users are suddenly locked out of the network functions that they depend upon in order to complete day-to-day tasks.

Obviously, in a world that depends on network communication, this means that large networks must include some sort of means to quickly correct any problems that might arise; these days, it has become increasingly common for networks to rely on an out of band management solution in order to make certain that network capabilities are always available when users need them.

Out of Band Management via Dial-Up

Friday, October 8th, 2010

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.

Why Do Most Large Corporate Networks Include an Out of Band Management Solution?

Tuesday, September 28th, 2010

Sometimes, it almost seems like network equipment has a built-in, evil sense of humor; it always seems to crash at the time that you need it the most, and when it does crash, it’s never a box that’s located just down the hall, it’s always some router or server located two states away, in a remote equipment cabinet at the end of a long, unpaved road in the middle of nowhere. This doesn’t mean that network equipment always has the last laugh though; especially if your equipment rack includes an out of band management solution.

Can Your Console Switch Tell You When Equipment is Misbehaving?

Saturday, August 28th, 2010

Most console switch products can provide network administrators with vital tools to allow management and troubleshooting capabilities for network devices at remote installation sites, but wouldn’t it be handy if your console switch could also automatically notify you when a network device ceases to function? WTI console switch products include a heartbeat feature, which when used in conjunction with our “Lost Communication” alarm, can immediately notify you when compatible devices, hang, fail, crash, or just stop working.

Do You Need to Know When Power to Network Devices has Been Interrupted?

Friday, August 27th, 2010

WTI RSM and TSM serial switch products include a power cycle alarm, which can be used to provide notification when power to the serial switch is interrupted for any reason. This may go without saying, but in most cases, when power to your serial switch has been interrupted, this generally means that power to your other rack mount network equipment has been interrupted too.
