SS7G2x Signaling Server SGW Mode User Manual Issue 4
4.9
FTP Access
The Signaling Gateway supports FTP server operation allowing the user to perform maintenance operations,
such as software, license and configuration update without the use of MML as well as providing access to
locally stored continuous records and periodic reports.
An FTP session should be established between the remote machine and the Signaling Gateway by entering
the appropriate command on the remote machine's keyboard, for example:
ftp 123.124.125.125
The FTP server can be activated or deactivated using the
FTPSER
parameter on the
CNSYS
command.
The appropriate user name and password to use depends on whether the
FTPPWD
option has been set to Y
using the
CNSYS
MML command.
When
FTPPWD
= Y, FTP access must use the fixed user name “siuftp” in conjunction with the normal MML
access password as configured by setting the
CNSYS
parameter
PASSWORD
.
Access to the Signaling Gateway using other user accounts except “siuftp” is denied. Note also that access is
denied if
FTPPWD
= Y, but there is no MML password.
When
FTPPWD
=N, no FTP access is permitted. Access with “siuftp” or any other user account is disabled.
Therefore, the user is strongly advised to activate
FTP
password security.
The state of
FTPPWD
can be viewed using the
CNSYP
command.
For additional security, the Signaling Gateway supports the use of Secure Shell (SSH) access for
FTP
operation. The user should use the
CNSYS
command to allow only secure FTP access to the unit, for
example:
CNSYS
:
SECURE
=Y;
For a client on a UNIX operating system, the command sequence to log in for FTP access using the sftp
application is:
sftp -l ftp@<IP Address>
The user is also prompted to enter the password for the siuftp login account.
The secure connection to a unit can also be established from Windows
®
operating system using the
appropriate SSH software.
