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 Console Switch with Outbound SSH and Outbound Telnet Capabilities

Wednesday, January 18th, 2012

When your primary means of communication with remote network equipment fails, it’s always good to have other options for contacting various devices in the remote network equipment rack. As long as you can communicate with the devices in the remote equipment rack, then you still have a chance of solving the communication problem without an expensive service call to the remote rack. Although a console switch provides the basis of an excellent out of band management solution, it can also be helpful if the console switch provides additional communication options that can be employed to communicate with other devices in the remote network equipment rack when your primary network is down or unavailable.


Outbound SSH/Telnet Provides Another Alternative for Console Switch Communication with Remote Network Devices

Wednesday, November 23rd, 2011

Most network administrators are already familiar with the concept of using a console switch to create an out of band connection to network elements at a remote equipment site, but it might come as a surprise to some that a console switch can also be used to provide out of band access to a local network at a remote equipment site. When network equipment cabinets are located so far off the beaten track that direct network communication with the cabinet is not possible, a console switch that supports outbound SSH/Telnet can be employed to allow users to access a local network at the remote site via dial-up connection, and then communicate with any device on the local network at the remote site.


A Server Console Switch with Outbound SSH and Telnet Provides More Communication Alternatives

Wednesday, October 5th, 2011

When implementing an out of band management solution for an offsite data center or remote network equipment rack, it’s best to include as many communication options as possible. The reason for this is simple; if problems with vital network elements at the remote site disrupt normal network communication, then you need an alternative channel of communication in order to be able to access the problematic network device and solve the problem without resorting to a service call. In cases like this, a server console switch with outbound SSH capabilities can provide network administrators with a versatile, alternative means of communication when normal network communication is not available.


Outbound SSH and Telnet: A Useful Feature for Linux Powered Console Servers

Wednesday, September 7th, 2011

When managing remote network devices located in offsite equipment cabinets, it’s always best to have as many options for communication with those remote devices as possible; in fact, the more options the better. When normal network communication is either unavailable or impractical, a Linux powered console server should be able provide several different alternatives for communication with vital network elements at a remote site in order to ensure that administrators will always be able to access console port command functions on remote devices, without the need to either visit the remote network equipment site in person, or send out a service team on an expensive truck roll.


A Linux Powered Console Server with Outbound SSH and Telnet Support

Network administrators who are charged with the task of managing off-site data centers and network elements in remote equipment racks know the value of an effective out of band management solution. When problems at remote network equipment sites disrupt normal network communication, an out of band management solution often provides the only means to remedy problems with remote network devices without physically traveling to the installation site and dealing with the problem in person. That’s why so many network administrators rely on a Linux powered console server to provide reliable, secure out of band communication with remote network equipment.


Using a Server Console Swith to Communicate with Network Devices at Remote Sites

Thursday, June 16th, 2011

When designing a remote network equipment site or off-site data center, it’s always important to ensure that IT support personnel in your central office have an avenue for out of band management of network elements at the remote equipment site. An out of band management solution ensures that even when your main network is down, tech support personnel will still be able to communicate with devices at the remote site without relying on expensive service calls and truck rolls. The most popular solution for providing out of band communication with devices at remote equipment sites, is to include a server console switch in the remote equipment rack.


A Server Console Switch Provides Communication When No Network Cable is Available

Friday, May 20th, 2011

Often, the remote nature of a network equipment site makes it impossible to connect a network cable directly to the remote site. Although the remote network equipment site might include a LAN which allows communication between the devices at the site, outside users such as network administrators back at company headquarters, aren’t able to directly communicate with the devices at the site via network cable. In cases like this, sometimes the only way to establish communication with devices at the remote site is create a modem connection to a server console switch ( at the remote site, and then use the server console switch’s outbound SSH or telnet capabilities to communicate via the LAN at the remote site.


A Console Access Server with Outbound SSH/Telnet Support Provides More Alternatives for Communication

Tuesday, April 26th, 2011

In out of band management applications that rely on a console access server ( for communication with remote network devices, reverse/outbound SSH/Telnet can be an extremely useful feature. In addition to providing a means to communicate with other network devices, outbound SSH/Telnet is also extremely handy in cases where an equipment rack is not connected to your main network, and the only way to communicate with devices in the rack is via dial-up or satellite modem.


Outbound SSH and Telnet Allows a Terminal Switch to Go Where a Network Cable Can’t Go

Monday, April 11th, 2011

A full featured terminal switch unit ( can often do a lot more than simply provide access to remote network elements when your main network is down. For example, if a terminal switch unit includes outbound SSH/Telnet capability, this allows administrators to create a dial-up connection with a remote terminal switch unit, and establish an SSH or Telnet connection with other devices that reside on the network at a remote site.
