Port Access Menu
Another default menu is the Port Access Menu, which is available to all users. Access to this menu can be established through a
Telnet or SSH session or through the web interface by selecting Serial ports > Connection > Port access menu connection.
Figure 54- The Port Access menu through the Configuration menu
Users access this menu through a Telnet or SSH session using the IP address of the SERIMUX followed by the port number
7000. Here is an example:
telnet 192.168.100.200 7000
By default root is connected to the command line interface and the preceding option allows the root user access to the port access
menu.
Configuring Remote Dial-In Access
Introduction
The SERIMUX supports dial-in connections from remote sites for out-of-band access. In this configuration, the SERIMUX has
serial ports configured for external modems and waits for dial-in connections from remote sites. If users dial-in using a terminal
application, the SERIMUX accepts the connection and displays a menu of available serials ports. In a dial-in terminal server
mode, the SERIMUX makes a TCP connection with either a Telnet or SSH client to a pre-defined server. RawTCP is also an
option for dial-in users.
For more information on the different types of Host mode configuration, see "Host Mode Configuration" on page 15.
