NIS server installation under LINUX

1. Prepared by
Dima Gomaa

2.  sudo apt-get install nis
 It will install NIS files
 It will ask for NIS server name let’s call it “NIS-server”
 sudo apt-get install portmap
 It will install portmap “is a server that converts RPC
program numbers into DARPA protocol port numbers. It
must be running in order to make RPC calls”

3.  vi /etc/default/portmap
 comment out the ARGS="-i 127.0.0.1" line

4.  vi /etc/default/nis
 Go to line NISSERVER = false and change it to true or
master
 In most of the documentation you will find it master as
there is another NIS server configured as slave one
 If you will use only one NIS server make it only true

5.  vi /etc/yp.conf
 Add line
 ypserver IP “where IP is the IP of the NIS Server”
 vi /etc/ypserv.seurenets
 hash the line contains 0.0.0.0
 allow the client machines that will connect to the NIS
server
 Add the line
 host IP “where IP is the IP of the client machines”

6.  build the database for the first time
 sudo /usr/lib/yp/ypinit –m

7.  sudo service portmap restart
 sudo service nis restart
 sudo make –C /var/yp

8.  useradd nisuser1
 passwd nisuser1 “and choose the password”
 cd/var/yp
 make
 To check if the users added correctly
 ypmatch nisuser1 passwd
 It will return the line of that user encrypted password
