Telnet - Acer ARMC_3P User Manual

C 4: U
HAPTER SAGE
The ARMC/3P features an embedded operating system and applications offering a
variety of standardized interfaces. This chapter will describe both these interfaces and
the way to use them in a more detailed manner. The interfaces are accessed using the
TCP/IP protocol family, thus they can be accessed using the built-in Ethernet adapter or
a modem, too.
The following interfaces are supported:
Full access is provided by the embedded web server. The ARMC/3P environment
can be entirely managed using a standard web browser. You can access the
ARMC/3P using the insecure HTTP protocol or using the encrypted HTTPS
protocol. Whenever possible use HTTPS.
A standard Telnet client can be used to access ay device connected to the
ARMC/3P's serial port via a terminal mode.
The ARMC/3P also offers SSH (Secure Shell) access as a secure alternative to

Telnet.

The primary interface of the ARMC/3P is the HTTP interface. This is covered extensively
in this chapter. Other interfaces are addressed in subtopics.
In order to use the Remote Console window of your managed host system, the browser
has to come with a Java Runtime Environment version 1.1 or higher. If the browser has
no Java support (such as on a small handheld device), you are still able to maintain your
remote host system using the administration forms displayed by the browser itself.
For an insecure connection to the ARMC/3P we can recommend the following web
browsers:
- Microsoft Internet Explorer version 5.0 or higher on Windows 98,
Windows ME, Windows 2000 and Windows XP
- Netscape Navigator 7.0, Mozilla 1.6 and Mozilla Firefox on Windows 98,
Windows ME, Windows 2000, Windows XP, Linux and other UNIX-like
Operating Systems
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. Some of the old browsers do not have a strong 128 Bit
encryption algorithm.
