Creating /etc/hosts from the NIS master
You can create a host file remotely and modify your storage system's NIS master to install the host file in the /etc directory. This method is useful if you have many entries in your host file.
Steps
- On the NIS server, open the NIS makefile with an editor.
- Locate the section for hosts.time.
- Add the following lines at the end of the hosts.time section,
replacing dirname with a directory name of your choice,
and toaster 1, toaster2, and so on with names of
your storage systems:
@mntdir=/tmp/dirname_etc_mnt_$$$$;\
if [ ! -d $$mntdir ]; then rm -f $$mntdir; \
mkdir $$mntdir; fi;\
for s_system in toaster1 toaster2 toaster3 ; do \
mount $$s_system:/etc $$mntdir;\
mv $$mntdir/hosts $$mntdir/hosts.bak;\
cp /etc/hosts $$mntdir/hosts;\
umount $$mntdir;\
done;\
rmdir $$mntdir
- Save the NIS makefile.
The /etc/hosts file on your storage system is updated whenever the
NIS makefile is run.
