5.6.3 Setting-up a network connection and configuring the networking environment for Linux
This section describes how to setup a network connection, and then to configure the networking
environment for use by Fast Models on a Linux platform.
The following instructions assume that your network provides IP addresses by DHCP. If this is
not the case, consult your network administrator.
Note
You must ensure that you first install the third-party IP package in the Fast Models networking
environment. See https://esl-support.arm.com/
Setting-up a network connection
To setup the network connection:
1. Ensure that you have installed the brctl utility on your system.
Note
This utility is included in the installation package, but you are recommended to use the
standard Linux bridge utilities, which are included in the Linux distribution.
2. In a shell, change to the bin directory of your Fast Models installation. For example, cd
/FastModelPortfolio_X.Y/ModelNetworking
3. You must run the scripts below from the directory in which they are installed, because they
will not work correctly if run from any other location:
• for a 32-bit operating system, run add_adapter_32.sh as root. For example, sudo
./add_adapter_32.sh
• for a 64-bit operating system, run add_adapter_64.sh as root. For example, sudo
./add_adapter_64.sh
4. At the prompt Please specify the TAP device prefix:(ARM), select Enter to accept the
default.
5. At the prompt Please specify the user list, type a space-separated list of all users who are
to use the model on the network, then select Enter. All entries in the list must be the
names of existing user accounts on the host.
6. At the prompt Please enter the network adapter which connect to the network:(eth0),
select Enter to accept the default, or input the name of a network adapter that connects to
your network.
7. At the prompt Please enter a name for the network bridge that will be
created:(armbr0), select Enter to accept the default, or input a name for the network
bridge. You must not have an existing network interface on your system with the selected
name.
8. At the prompt Please enter the location where the init script should be
written:(/etc/init.d/FMNetwork), select Enter to accept the default, or input another
path with a new filename in an existing directory.
9. At the prompt WARNING: The script will create a bridge which includes the local
network adapter and tap devices. You may suffer temporary network loss. Do you
want to proceed? (Yes or No), check all values input so far, and type Yes if you wish to
proceed. If you type No, no changes are made to your system.
