After installing the SunFDDI driver software, you must create a hostname file for the adapter's interface. You must also create both an IP address and a host name for the interface in the /etc/hosts file.
At the command line, use the grep command to search the /etc/path_to_inst file for pf or nf devices.
# grep pf /etc/path_to_inst "/pci@1f,2000/pci@2/pf@0" 0 "pf"
In the example above, the pf@0 instance shows a SunFDDI PCI adapter installed in slot 1.
# grep nf /etc/path_to_inst "/sbus@1f,0/SUNW,nf@1,7880" 1 "nf"
In the example above, the nf@1 instance shows a SunFDDI SBus adapter installed in slot 2.
Create an /etc/hostname.pfnum or hostname.nfnum file, where num is the instance number of the interface you plan to use.
Do not create /etc/hostname.nfnum or hostname.pfnum files for SunFDDI adapter network interfaces you plan to leave unused.
The /etc/hostname.nfnum or hostname.pfnum file must contain the host name for the appropriate network interface.
The host name should have an IP address that will need to 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.hme0 and /etc/hostname.nf1 cannot share the same host name.
Using the instance example in SBus Step 1, the following example shows the /etc/hostname.nfnum files required for a system called zardoz that has a SunFDDI adapter (zardoz-11).
# cat /etc/hostname.hme0 zardoz # cat /etc/hostname.nf0 zardoz-11
