4.9FTP 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.
