Configuring The Network Host Files - Sun Microsystems x4422a User Manual

Configuring the Network Host Files

After installing the driver software, you must create a hostname.ce# file (Where
# = the instance number of the ce interface.) 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.
1. At the command line, use the grep command to search the /etc/path_to_inst
file for ce interfaces.
# grep ce /etc/path_to_inst
"/pci@1e,600000/pci@4/network@0" 0 "ce"
"/pci@1e,600000/pci@4/network@1" 1 "ce"
In the example above, the device instance is from a Sun Dual Gigabit Ethernet and
Dual SCSI/P adapter. For clarity, the instance number is in bold italics.
2. Use the ifconfig command to setup the adapter's ce interface.
Use the ifconfig command to assign an IP address to the network interface. Type
the following at the command line, replacing ip_address with the adapter's IP
address:
# ifconfig ce0 plumb ip_address up
Refer to the ifconfig(1M) man page and the Solaris documentation for more
information.
If you want a set-up that will remain the same after you reboot, create an
/etc/hostname.cenumber file, where number corresponds to the instance
number of the ce interface you plan to use.
To use the adapter's ce interface in the Step 1 example, create an
/etc/hostname.ce0 file, where 0 is the number of the ce interface. If the
instance number were 1, the filename would be
/etc/hostname.ce1.
Do not create an /etc/hostname.ce# file for a Sun Dual Gigabit Ethernet and
Dual SCSI/P adapter interface you plan to leave unused.
The /etc/hostname.ce# file must contain the hostname for the appropriate ce
interface.
The host name should have an IP address and should be listed in the
/etc/hosts file.
