How to add a user to NIS (YP)

Some people may still be using NIS (Yellow Pages) despite the security issues associated with
this service, so here’s how to create a new user on NIS master.

1. Go to the yp source directory.

# cd /var/yp/src

2. Make a backup copy of password file, edit the passwd file and add new user. Make sure that
the uid is unique.

# cp passwd passwd.[current date]
# vi passwd

3. Create a home directory for new user (if necessary)

# mkdir /home/[username]

4. Run make.

# cd /var/yp
# make

5. Confirm that the user has been successfully added

# ypcat passwd | grep [username]
