NIS server processes

To verify the NIS server is running:


ps -ef | grep yp


root      1938     1  0 11:22 ?        00:00:00 /usr/sbin/ypserv
root      1941     1  0 11:22 ?        00:00:00 /usr/sbin/rpc.yppasswdd -D /etc -e chsh
root      1944     1  0 11:22 ?        00:00:00 /usr/sbin/rpc.ypxfrd

Alternatively, it can be chacked through rpcinfo command:


rpcinfo -p | grep yp


    100004    2   udp    844  ypserv
    100004    1   udp    844  ypserv
    100004    2   tcp    847  ypserv
    100004    1   tcp    847  ypserv
    100009    1   udp    846  yppasswdd
 600100069    1   udp    849  ypxfrd
 600100069    1   tcp    851  ypxfrd

To see if a client can access the NIS services on the NIS server, for example node18, run rpcinfo on the client host:


rpcinfo -p node18 | grep yp

To start NIS services at boot-up time, run


update-rc.d portmap defaults
update-rc.d nis defaults
