Configuring PortsPorts Configuring Introduction This chapter provides information on configuring serial ports. Key port configuration attributes include the host mode, which defines a type of communication between the port and a remote host, the protocol, authentication, user access restrictions, and serial communication attributes. Host Mode Configuration The SERIMUX provides four modes of communication between serial devices and remote hosts.
Dial-In Modem Mode In this mode, the SERIMUX assumes an external modem is attached to the serial port and is waiting for a dial-in connection from a remote site. When a user dials-in using a terminal application, the SERIMUX accepts the connection and displays a menu listing available serial ports. Users can then select a serial port and access the devices attached to the SERIMUX by selecting the serial port number from the menu.
Configuring Host Mode To configure a serial port for host mode, enter the values in the applicable fields. To access the Host mode configuration screen, do the following: 1. Access the web interface. 2. Under the Serial Port heading, choose Configuration. 3. Choose All or an Individual port > Host mode configuration. 4. Fill in the highlighted fields as they apply to your configuration.
Supported Protocols In configuring a serial port, the user has three protocol options. The three protocols available are: RawTCP, SSH, and Telnet. • Choose SSH as the protocol for users logging in from an SSH client program to access a port. • Choose RawTCP for users connecting directly to a TCP socket. • Choose Telnet for users logging in from a Telnet client program and accessing the ports. Use the Host mode configuration page in the web interface to select the correct protocol.
Using the Configuration Menu Host Mode Configuration 1. Access the configuration menu. 2. Choose Serial port configuration > an individual port number or 0 (zero) for all ports > Host mode configuration. Figure 23- Configure Host mode via Configuration menu 3.

Access the configuration menu. 2.
System andPort Port Logging System and Logging Introduction The SERIMUX provides four options for saving system and port logs. The options are: a syslog server, NFS server, compact-flash card, and the SERIMUX memory. When memory is selected as the storage location, log files are saved to volatile memory, meaning files are lost when the power is turned off. To use a syslog server, an NFS server, or a compact-flash card, the user must first enable the devices and enter the required information.
Figure 26- NFS server configuration menu Enable A Compact-flash Card The compact-flash card must be installed and configured on the SERIMUX before it can be used for system logging or storing SERIMUX configuration information. See Adding a Compact-flash Card on page 11. Enable SERIMUX Memory The SERIMUX memory is already enabled for port logging and only needs to be configured for system or port logging. See Configuring System Logging Services (next section).
Figure 27- Configure system logging services Viewing System Logs The system logs can be viewed from the web interface on the System logging page or from the location where they have been saved. The following table lists the file locations of the system logs.
Figure 28- Port logging menu Viewing Port Logs The port logs can be viewed from the web interface on the Port logging page or from the location where they have been saved. The following table lists the file locations of the system logs.

Configuring SMTP Alerts Most SMTP servers check the sender’s email address with the host domain name to verify the address as authentic. Consequently, when assigning an email address for the device email address, any arbitrary username with the registered hostname may be used. An example is username@company.com. To configure the SERIMUX for SMTP alerts, the following parameters are required: • SMTP server: Use either the hostname or the IP address.
Configuring SNMP To configure the SERIMUX for SNMP do the following: 1. Access the SERIMUX web interface. 2. Under the Network heading, choose SNMP configuration. 3. Fill in information for the MIB-II system objects section and choose Yes under EnableAuthenTrap. • sysContact: Identity of the contact person managing the MIB-II system. • sysName: The name identifying the system. By convention, this is the fully qualified domain name of the SERIMUX unit.. An example is:SERIMUX@companyname.com.
Managing the SNMP Protocol The SERIMUX SNMP protocol can be managed using an NMS or SNMP browser. However, before the NMS or SNMP browser can access the data, the Access control settings must list the IP address of the host from which the browser is executed. See the preceding graphic for details. Configuring Port Event Handling Once an SMTP or SNMP server has been configured, it can be used to send port-related alerts and notifications.
Using the Configuration Menu Configuring SNMP To configure SNMP from the configuration menu, do the following: 1. Access the Configuration menu. 2. Choose Network configuration > SNMP configuration. Figure 35- Configure SNMP via Configuration menu 3. Enter the desired parameters for the menu items. 4. Use the ESC key when all parameters are entered to return to the main menu. 5.

Configuring Security and Authentication Configuring Security and Authentication Introduction The SERIMUX provides several ways to control access to the network and the devices on the network. One method is through IP filtering, which allows or prevents users with specific IP addresses from accessing devices or serial ports on the network. IP filtering can be permitted or restricted for all ports globally or on a per port basis. Another access control method involves restricting or permitting specific users.
The following table displays examples of allowed remote hosts. Input format Allowable Hosts Base Host IP Address Subnet mask Any host 0.0.0.0 0.0.0.0 192.168.1.120 192.168.1.120 255.255.255.255 192.168.1.1 - 192.168.1.254 192.168.1.0 255.255.255.0 192.168.0.1 192.168.255.254 192.168.0.0 255.255.0.0 192.168.1.1 - 192.168.1.126 192.168.1.129 192.168.1.254 192.168.1.0 192.168.1.128 255.255.255.128 255.255.255.
Figure 40- Configure User access control Sniff Session A Sniff Session enables multiple users to access a single serial port for viewing the data stream. Users who are registered for a sniff session can access a specific serial port even if another user is using the port. The SERIMUX supports multiple concurrent sniff sessions. • Allow all users to sniff: When checked, all users with permission to access the port can participate in sniff sessions.

Port Clustering Port Clustering Introduction Port clustering is the ability to manage many serial ports on one or multiple slave devices from one master device using a single IP address. For instance, the SERIMUX can manage up to 16 slave devices or a maximum 544 serial ports with one Master device. Ports can be configured either collectively or individually depending on user preference. Each master and slave device is configured separately; they cannot be configured from one master console.
Figure 62- Configure Slave ports on the Master Unit . 4. Select Enable from the "Enable/Disable this unit" drop down menu. A new configuration screen appears. Figure 63- Enable a Slave unit and setup the port information 5. Enter the IP address of the slave unit in the IP address field. 6. Select the Auto Config button and the Master SERIMUX automatically imports the configuration of the Slave serial ports to the Master SERIMUX.
Figure 64- Setup clustering parameters • Base destination port: This is the physical port number on a remote slave unit. By default the base destination port on the first slave unit is 7001. However, the user can change the base destination port number to another number and the rest of the ports on the unit will be sequentially numbered from the base destination port. For example, starting the base destination port number with 7010 results in a 32-port unit being numbered from 7010 to 7041.
Command Line Line Interface Command Interface Introduction The SERIMUX runs the embedded Linux Hard Hat operating system. The command line interface for configuration purposes is accessible only by the root user. The system administrator has read only privileges from the command line. By default the root user is connected to the CLI (command line interface) when Telnetting to the SERIMUX. To gain access to the command prompt, the root user uses the username root and the root password.
Important File Locations The SERIMUX has several files that are important for administrative use. Below is a brief listing of some files that the root user or system administrator might desire to either monitor or edit. Default Script The default script file is executed whenever the SERIMUX is booted. The file is /usr/rc.user and can be modified with the vi editor. The modified script becomes effective when the system is rebooted. Booting Sequence When the SERIMUX boots, it uncompresses the /cnf/cnf.tar.
The alternative method to reset the unit is through the web interface. The web interface provides the option of retaining the IP settings. To use the web interface to reset the SERIMUX, do the following: 1. Access the web interface. 2. Under the System administration heading choose Configuration Management.
