Chapter 3 Installation and Initial Configuration
Note: The protocol and mode parameters are only present if licensed. When a protocol or mode is
active, the parameter shows the value “Y”, and when inactive, the parameter shows the value
“N”.
The new IP address parameters is initialized with immediate effect. If the IP address used to login to the unit
for the
telnet
session is changed, the user is automatically logged out of the session. However, the user can
log in again without delay using the new IP address.
The Ethernet connection should be verified by attempting to “ping” the SGW from a computer connected to
the same Ethernet network, using the following command:
ping 123.124.125.126
If the Signaling Gateway has been configured correctly, it responds to the
ping
and the host machine displays
a message confirming communication with the Signaling Gateway (the exact format and response of this
message is operating system dependant).
If
ping
fails, the user should check that the IP address was entered correctly and that there is no fault with
the cabling to the Signaling Gateway.
Once the
ping
command shows that the Ethernet connection is valid, it should be possible to access the
management interface previously used on the VT100 compatible terminal via
telnet
. This is achieved by
establishing a
telnet
session to port 8100 or 8101.
Note: It is not possible to
telnet
to the standard
telnet
port 23.
For example, on a typical host console, the following command starts a
telnet
session to a Signaling Gateway
with an IP address of 123.124.125.126:
telnet 123.124.125.126 8100
The
telnet
terminal displays the MML interface prompt:
SS7G20(SGW) logged on at 2004-01-20 14:52:29
<
An optional password can be set to control remote access to the MML. This is also done using the
CNSYS
command:
CNSYS
:
PASSWORD
=password,
CONFIRM
=password;
If set, a user opening a
telnet
session to the MML is prompted to enter a password, for example:
SS7G20(SGW) logged on at 2004-01-20 14:52:29
password:
Password access can be removed by specifying “null” values for the
PASSWORD
and
CONFIRM
parameters,
that is:
CNSYS
:
PASSWORD
=,
CONFIRM
=;
For additional security, the units support the use of Secure Shell (SSH) tunnelling for
telnet
and secure FTP
operation. The user should use the CNSYS command to restrict
telnet
access to "
telnet
via SSH tunnelling"
only. For example:
CNSYS
:
SECURE
=Y;
Note: The unit does not provide a Secure Shell session connection. Your SSH client may need additional
configuration to allow SSH tunnelling without a session connection.
