Chapter 3 Installing and Configuring the Client Adapter
Additional Procedures
Note Because PCI client adapters are installed inside desktop computers, you should have little reason
to remove the adapter. However, instructions are provided in the “Removing the Client Adapter”
section on page 7-6 in case you need to remove your PCI client adapter.
Additional Procedures
After the driver and client utilities are properly installed, you might need to perform additional
procedures before using your client adapter. This section provides instructions for the following
procedures:
• Changing the permission rights regarding configuration of the client adapter
• Assigning an IP address
• Installing the drivers for more than one client adapter and then selecting among them
Changing the Permission Rights
By default, all users are permitted to configure the client adapter. If you want only root users (those with
administrative rights) to be able to run the client utilities and configure the client adapter, type
chmod 500 /opt/cisco/bin/* and press Enter.
Assigning an IP Address
You can obtain a dynamic IP address with the Dynamic Host Configuration Protocol (DHCP), or you
can manually configure a static IP address.
Configuring for a DHCP Assigned Address
If you want your computer’s IP address to be assigned by DHCP and your network has a DHCP server,
you must run a DHCP client utility. The two most popular client utilities are dhcpcd and pump. Most
Linux distributions should have one of them. If you have neither, you must install one from your
distribution CD-ROM or download one from the Internet. Refer to your distribution's home page for
more information.
On Red Hat and other distributions that include the linuxconf utility, you should use this utility to
configure DHCP on your computer.
Note You must be logged in as root or have equivalent superuser privileges.
Note If you are using a distribution that uses another utility, such as Slackware’s netconfig, follow the
distribution’s recommendations for configuring DHCP.
