4. Usage
Introduction
The IP-KVM features an embedded operating system and applications offering a variety of
standardized interfaces. This chapter describes using these interfaces.
4.1 Prerequisites
The interfaces are accessed using the TCP/IP protocol family, thus they can be accessed using
either LAN port on the device. The following interfaces are supported:
•
HTTP/HTTPS This provides full access to the embedded web server so the IP-KVM
environment can be managed using a standard web browser. You can access the IP-KVM
using the insecure HTTP protocol, or using the encrypted HTTPS protocol. It is
recommended whenever possible to use HTTPS. HTTP/HTTPS is the primary interface of
the IP-KVM and it is covered extensively in this chapter
•
Telnet A standard Telnet client can also be used to access an arbitrary device connected to
the IP-KVM's serial port via a terminal mode. However this is not the primary interface and
is addressed in subtopics
4.1.1 Browser
In order to use the Remote Console window of your managed host system, the browser has to
come with a Java Runtime Environment version 1.5 or above. If the browser has no Java support
(such as on a small handheld device), you are still able to maintain your IP-KVM using the
administration forms displayed by the browser itself.
Your web browser also must be configured to accept cookies or else login is not possible.
In order to access the remote host system using a securely encrypted connection you need a
browser that supports the HTTPS protocol. Strong security is only assured by using a key length of
128 bit and some of the old browsers do not have a strong 128 bit encryption algorithm. You
should check your browser (e.g. for Internet Explorer select Help:About )
