System Services
Communication ports
Ports 22 (SSH) and 23 (TELNET) are closed for security reasons in the default
configuration in the firmware version 2.3.0 and later. To open them use a console or
this configuration tool. Enter the "root" login for Telnet or SSH. The password is not
defined by default. You are strongly recommended to set the password! The password
setting command syntax is as follows:
passwd root <Enter>
Changing password for root
New password: <Enter>
Retype password: <Enter>
The password will be changed regardless of the original password. If you forget your
password, you can change it any time in the same way. All you have to know is your
console login name.
Use the "Admin" login for the console and password "2n" (by default).
If you, despite recommendations, use the TELNET and SSH protocols
for login to the NetStar PBX, any software warranty provided by the
manufacturer shall be null and void. The system access is logged and
intended for servicing purposes only.
