Chapter 4: Serial Port, Device and User Configuration
70
Console Server & RIM Gateway User Manual
automatically make changes to their local configurations (and only make those changes that relate to its particular serial
ports).
You can still use the local Slave Management Console to change the settings on any Slave serial port (such as alter the
baud rates). However these changes will be overwritten next time the Master sends out a configuration file update.
Also while the Master is in control of all Slave serial port related functions, it is not master over the Slave network host
connections or over the Slave
console server system itself.
So Slave functions such as IP, SMTP & SNMP Settings, Date &Time, DHCP server must be managed by accessing each
Slave directly and these functions are not over written when configuration changes are propagated from the Master.
Similarly the Slaves Network Host and IPMI settings have to be configured at each Slave.
Also the Master’s Management Console provides a consolidated view of the settings for its own and all the Slave’s serial
ports, however the Master does not provide a fully consolidated view. For example if you want to find out who's logged in
to cascaded serial ports from the master, you’ll see that
Status: Active Users only displays those users active on the
Master’s ports, so you may need to write custom scripts to provide this view. This is covered in Chapter 11.
4.7 Serial Port Redirection (PortShare)
Opengear’s Port Share software delivers the virtual serial port technology your Windows and Linux applications need to
open remote serial ports and read the data from serial devices that are connected to your
console server .
PortShare is supplied free with each console server and you are licensed to install PortShare on one or more
computers for accessing any serial device connected to a console server port.
PortShare for Windows
The portshare_setup.exe program is included on the CD supplied with your console server. A copy can be freely
downloaded from the ftp site. Refer to the PortShare User Manual and Quick Start for details on installation and
operation
PortShare for Linux
The PortShare driver for Linux maps the console server serial port to a host tty port. Opengear has released the
portshare-serial-client as an open source utility for Linux, AIX, HPUX, SCO, Solaris and UnixWare. This utility can
be freely downloaded from the ftp site.
This PortShare serial port redirector allows you to use a serial device connected to the remote console server as if it
were connected to your local serial port. The portshare-serial-client creates a pseudo tty port, connects the serial
application to the pseudo tty port, receives data from the pseudo tty port, transmits it to the console server through
network and receives data from the console server through network and transmits it to the pseudo-tty port.
