10. At the prompt that informs you of the changes that the script is to make to your system,
input Yes if you are happy to accept these changes, or input No to leave your system
unchanged.
Warning
After entering Yes, you might temporarily lose network connectivity. Also, the IP address
of the system might change.
11. The network bridge is disabled after the host system is reset. If you want the host system
to be configured to support RTSM bridged networking, you might have to create links to
the init script (FMNetwork) in appropriate directories on your system. The script
suggests some appropriate links for Red Hat Enterprise Linux 5.
Note
You only have to perform the above steps once, at the beginning.
Configuring the networking environment
Using System Canvas or a related Fast Models tool, load the required project or model and select
your component. For more information, see the Fast Models User Guide.
Set the following parameters on the HostBridge and SMSC_91C111 components. Enter:
hostbridge.interfaceName="ARM"
smsc_91c111.enabled=1
where ARM is the adapter built into the network bridge.
Note
Firewall software might block network traffic in the network bridge, and might result in a
networking failure in the model. If the model does not work after configuration, check the
firewall settings.
5.6.4 Disabling and re-enabling networking
You can disable RTSM networking without having to uninstall it. Use the installed init script
(by default, /etc/init.d/FMNetwork) for this purpose.
To disable RTSM networking, invoke the init script as root with the parameter stop. For
example, sudo /etc/init.d/FMNetwork stop. To re-enable RTSM networking, invoke the init
script as root with the parameter start. For example, sudo /etc/init.d/FMNetwork start.
Warning
These operations remove/restore TAP devices and the network bridge. There is a temporary loss
of network connectivity and your IP address might change.
5.6.5 Uninstalling networking
To uninstall networking:
1. In a shell window, change to the bin directory of your Fast Models installation. For
example, cd /FastModelPortfolio_X.Y/ModelNetworking
2. Run remove_adapters.sh as root, passing the location of the init script (FMNetwork) as
an argument. For example, sudo ./remove_adapters.sh /etc/init.d/FMNetwork
