Remote Access to Console Ports via GigE Networks

Friday, March 18th, 2016

At one time in the not-too-distant past, a service call or truck provided the only workable solution for dealing with unresponsive routers or switches that had crashed and disrupted network communication. Although this approach (eventually) took care of the problem, it also resulted in excessive expenses, hassles and network downtime while you waited for your service team to arrive on-site. Fortunately, thanks to devices such as GigE Serial Console Servers, there are now other, more effective ways to deal with network outages.

Managing Pipeline Monitoring Stations in Public Utilities Networks

Thursday, August 20th, 2015

Large enterprise networks, like those found in public utilities applications, present many unique challenges when implementing an out-of-band management solution. Due to the sheer size and complexity of most public utilities networks, an effective out-of-band management solution must provide sufficient scalability to meet the needs of both large equipment sites such as data centers and also small equipment sites such as pipeline monitoring stations.

Managing Devices at Remote Branch Offices in Large Enterprise Networks

Monday, August 17th, 2015

When a critical network element located at a remote branch office malfunctions and disrupts network communication, an out-of-band management solution allows tech support personnel to address the problem immediately, without the hassles, expenses or delays associated with a physical truck roll or service call. When an effective out-of-band management solution is deployed at a remote branch office, personnel at the NOC can promptly access console port command functions on the remote device or execute a reboot without the need to actually travel to the site in person, minimizing downtime and ensuring that vital network based services are available when needed.

Managing Devices at Remote Data Centers in Large Enterprise Networks

Monday, August 10th, 2015

An effective out-of-band management solution for large enterprise network applications must be able to serve the needs of a wide variety of different types of remote network equipment sites. In order to minimize downtime and ensure access to vital services, an out-of-band management solution in a large enterprise network must be able to provide remote power reboot control and console access for critical network elements located at remote data centers, microwave antenna sites, branch offices and many other diverse types of remote installations.

How to Avoid Potential Pitfalls when Implementing an Out-of-Band Management Solution in a Large Enterprise Network

Monday, August 3rd, 2015

The task of designing an out-of-band management solution for a large enterprise network presents a number of different challenges that are not commonly encountered in smaller scale out-of-band management solutions. In addition to the sheer size and scope involved in large enterprise networks, an effective out-of-band solution must also be able to address many other issues and must include the need to adapt to a variety of different sized remote equipment sites with varying power needs and communication capabilities.

Enterprise Management for Devices on LANs behind 3G/4G/Cellular Routers

Thursday, May 28th, 2015

Cellular routers often present an unexpected challenge for many enterprise management programs. Although the enterprise management program can easily find the IP address for the cellular router, many enterprise programs can’t find devices located behind the cellular router due to the use of port forwarding or port address translation (PAT.) WTI’s WMU Enterprise Management Solution solves this problem by providing the ability to search a range of port numbers associated with the router’s IP address.

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.

Using Reverse SSH to Manage Remote Network Elements

Monday, April 20th, 2015

In addition to providing a secure, encrypted alternative to Telnet communication, SSH (or Secure Shell Protocol,) can also be used for communication with remote devices located at distant network equipment facilities. Reverse SSH commands can simplify the process of communicating with devices protected by firewalls and also allow communication with isolated LAN segments that are normally only accessible via dial-up or local command port.

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.

Secure Out-of-Band Console Access via Dual Ethernet For Financial Applications

Monday, March 10th, 2014

Challenge:

One of the largest North American credit card companies has data centers across the world that house a large installed base of 10G firewalls, IDS sensors, load balancers and routers that support its day-to-day security operations activities. The credit card company has a requirement to be able to securely manage these devices out of band when the primary network path is unavailable.

The NOC team wanted to implement the latest security protocols, logging capability and connectivity options for both in-band and out-of-band management appliances. The company also wanted the console server to have dual Ethernet ports , simultaneous log-in, radius security authentication, event logging and alarming, and enterprise management software to manage all of their out-of-band management equipment through a single portal.
