10.25.1. Installation of Iana-Etc

[Note]

Note

This package has the option of downloading updated data when internet access is available. If /etc/resolv.conf has a nameserver entry and internet access is available at this step, then apply the IANA get patch and get the updated data: 

patch -Np1 -i ../iana-etc-2.30-get_fix-1.patch
make get

Do not apply the following patch.

The following patch updates the services and protocol files: 

patch -Np1 -i ../iana-etc-2.30-numbers_update-20120610-2.patch

The following command converts the raw data provided by IANA into the correct formats for the /etc/protocols and /etc/services data files: 

make
