NIS client commands

To verify the NIS client (ypbind) is running:


ps -ef | grep yp


root      3598     1  0 Feb21 ?        00:00:00 /usr/sbin/ypbind

Alternatively, it can be checked through rpcinfo command:


rpcinfo -p | grep yp


    100007    2   udp    808  ypbind
    100007    1   udp    808  ypbind
    100007    2   tcp    811  ypbind
    100007    1   tcp    811  ypbind

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

To check the server name the client is bound to:


ypwhich

To check on available NIS maps:

 
ypcat -x

A user or uid entry quiry in the password map:


ypmatch mike passwd.byname
ypmatch 3112 passwd.byuid

To query the whole password map:

 
ypcat passwd

To check the NIS domain name:


domainname

To change NIS password:


yppasswd
