Configuring The Network Host Files; To Configure The Network Host Files - Sun Microsystems GigabitEthernet FC-AL/P Combination Adapter Installation Manual

Configuring the Network Host Files

After installing the GigabitEthernet driver software and the adapter, you must create
a hostname.genumber file for the adapter's Ethernet interface. You must also create
both an IP address and a host name for its Ethernet interface in the /etc/hosts file.

To Configure the Network Host Files

1. At the command line, use the grep command to search the /etc/path_to_inst
file for ge interfaces.
# grep ge /etc/path_to_inst
"/pci@1f,2000/pci@1/network@4" 0 "ge"
In the example above, the device instance is from the Sun GigabitEthernet FC-AL/P
Combination adapter. For clarity, the instance number is in bold italics.
2. Set up each hostname.genumber file to correspond with each ge device in the
path_to_inst file.
To use the adapter's ge interface in the above example, you would need to create an
/etc/hostname.ge0 file, where 0 is the instance number of the ge interface. If the
instance number were 2, the file name would be /etc/hostname.ge2.
Do not create an /etc/hostname.genumber file for a Sun GigabitEthernet
FC-AL/P Combination adapter interface you plan to leave unused.
The /etc/hostname.genumber file must contain the host name for the
appropriate ge interface.
The host name should have an IP address and should be entered in the
/etc/hosts file.
The host name should be different from any other host name of any other
interface; for example /etc/hostname.ge0 and /etc/hostname.hme1 cannot
share the same host name.
The following example shows the /etc/hostname.genumber file required for a
system called cartman that has a Sun GigabitEthernet FC-AL/P Combination
adapter (cartman-11).
# cat /etc/hostname.hme0
cartman
# cat /etc/hostname.ge0
cartman-11
