5.3.4 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>
- Change 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).
Warning
- 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.
Menu System
To open or close a port using the configuration tool, go to the Network – Service setting – System services menu and use the Enabled or Disabled options. The meanings of the options are as follows:
- Internal server of Assistant – open or close access to the Assistant web server (user web application).
- Telnet server – open or close access to the system via the Telnet protocol.
- SSH server – open or close access to the system via the SSH protocol.
- Trace level – enable the Linux level for trace message displaying. This option is especially useful if you need to supervise the PBX remotely with a poor connection.
- All – all available trace messages. Basic settings.
- None – discontinue all trace messages.
- Call mng – messages related to call routing by the PBX.
- Stack – just messages related to call processing on the PBX interfaces (GSM, ISDN, SIP, analogue).
- HEAP – write out the PBX memory load messages in special development firmware versions only.
