Administering ttymon Port Monitors

Console administration for ttymon is now managed by SMF. Use the svccfg command to set ttymon system console properties. Continue to use the SAF command, sacadm, to add, list, remove, kill, start, enable, disable, enable, and remove ttymon port monitors.

How to Set the ttymon Console Terminal Type

This procedure shows how to change the console terminal type by using the svccfg command.

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Run the svccfg command to set the property for the service instance that you want to change.
    # svccfg -s console-login setprop ttymon/terminal_type = "xterm"

    where “xterm” is an example of a terminal type that you might want to use.

  3. (Optional) Restart the service instance.
    # svcadm restart svc:/system/console-login:default

    Caution - If you choose to restart the service instance immediately, you are logged out of the console. If you do not restart the service instance immediately, the property changes apply at the next login prompt on the console.


How to Set the Baud Rate Speed on the ttymon Console Terminal

This procedure shows how to set the baud rate speed on the ttymon console terminal. Support for console speeds on x86 based systems are dependent on the specific platform.

The following are supported console speeds for SPARC based systems:

  • 9600 bps

  • 19200 bps

  • 38400 bps

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Use the eeprom command to set a baud rate speed that is appropriate for your system type.
    # eeprom ttya-mode=baud-rate,8,n,1,-

    For example, to change the baud rate on an x86 based system's console to 38400, type:

    # eeprom ttya-mode=38400,8,n,1,-
  3. Change the console line in the /etc/ttydefs file as follows.
    console baud-rate hupcl opost onlcr:baud-rate::console
  4. Make the following additional changes for your system type.

    Note that these changes are platform-dependent.

    • On SPARC based systems: Change the baud rate speed in the /kernel/drv/options.conf file.

      Use the following command to change the baud rate to 9600.

      # 9600 :bd: ttymodes="2502:1805:bd:8a3b:3:1c:7f:15:4:0:0:0:11:13:1a:19:12:f:17:16";

      Use the following command to change the baud rate speed to 19200.

      # 19200 :be: ttymodes="2502:1805:be:8a3b:3:1c:7f:15:4:0:0:0:11:13:1a:19:12:f:17:16";

      Use the following command to change the baud rate speed to 38400.

      # 38400 :bf: ttymodes="2502:1805:bf:8a3b:3:1c:7f:15:4:0:0:0:11:13:1a:19:12:f:17:16";
    • On x86 based systems: Change the console speed if the BIOS serial redirection is enabled. The method that you use to change the console speed is platform-dependent.

How to Add a ttymon Port Monitor

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Add a ttymon port monitor.
    # sacadm -a -p mbmon -t ttymon -c /usr/lib/saf/ttymon -v `ttyadm
    -V` -y "TTY Ports a & b"
    -a

    Specifies the add port monitor option.

    -p

    Specifies the pmtag mbmon as the port monitor tag.

    -t

    Specifies the port monitor type as ttymon.

    -c

    Defines the command string used to start the port monitor.

    -v

    Specifies the version number of the port monitor.

    -y

    Defines a comment to describe this instance of the port monitor.

How to View ttymon Port Monitor Status

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. View the status of a ttymon port monitor.
    # sacadm -l -p mbmon
    -l

    Specifies the list port monitor status flag.

    -p

    Specifies the pmtag mbmon as the port monitor tag.

Example 3-1 Viewing ttymon Port Monitor Status

This example shows how to view a port monitor named, mbmon.

# sacadm -l -p mbmon
PMTAG  PMTYPE  FLGS RCNT STATUS    COMMAND
