5. Use t he tex t editor of your choice to edit the /etc/yp.conf file and add the foll o wi ng
line, where domain_name is the NIS domain name and NIS_slave_name i s either
the IP address or host n ame of the slave NIS server (the head node):
domain domain_name server NIS_slave_name
6. Save your changes and exit the file.
7. Use the text edito r of yo ur c h oice to edit the /etc/sysconfig/iptables.proto
file to o pen ports for the yp client, yp server, and yp transfer service on the various
network adapters. Each entry m ust appear on a single, contin uou s line as shown in t he
following example; entries canno t wrap to the next line. You m ust add your entries before
the REJECT statement at the bottom of the file:
# setup ypserv server on port 831 on external adapter
-A RH-Firewall-1-INPUT -i External -p tcp -m tcp --dport 831 -j ACCEPT
-A RH-Firewall-1-INPUT -i External -p udp -m udp --dport 831 -j ACCEPT
# setup ypxfrd server on port 832 on external adapter
-A RH-Firewall-1-INPUT -i External -p tcp -m tcp --dport 832 -j ACCEPT
-A RH-Firewall-1-INPUT -i External -p udp -m udp --dport 832 -j ACCEPT
# setup ypbind client on port 830, loopback only
-A RH-Firewall-1-INPUT -i lo -p tcp -m tcp --dport 830 -j ACCEPT
-A RH-Firewall-1-INPUT -i lo -p udp -m udp --dport 830 -j ACCEPT
# setup ypserv server on port 831 on loopback connection
-A RH-Firewall-1-INPUT -i lo -p tcp -m tcp --dport 831 -j ACCEPT
-A RH-Firewall-1-INPUT -i lo -p udp -m udp --dport 831 -j ACCEPT
# setup ypxfrd server on port 832 on loopback connection
-A RH-Firewall-1-INPUT -i lo -p tcp -m tcp --dport 832 -j ACCEPT
-A RH-Firewall-1-INPUT -i lo -p udp -m udp --dport 832 -j ACCEPT
# setup ypserv server on port 831 on management LAN
-A RH-Firewall-1-INPUT -i Admin -p tcp -m tcp --dport 831 -j ACCEPT
-A RH-Firewall-1-INPUT -i Admin -p udp -m udp --dport 831 -j ACCEPT
# setup ypxfrd server on port 832 on management LAN
-A RH-Firewall-1-INPUT -i Admin -p tcp -m tcp --dport 832 -j ACCEPT
-A RH-Firewall-1-INPUT -i Admin -p udp -m udp --dport 832 -j ACCEPT
# setup ypserv server on port 831 on interconnect adapter
-A RH-Firewall-1-INPUT -i Interconnect -p tcp -m tcp --dport 831 -j ACCEPT
-A RH-Firewall-1-INPUT -i Interconnect -p udp -m udp --dport 831 -j ACCEPT
# setup ypxfrd server on port 832 on interconnect adapter
-A RH-Firewall-1-INPUT -i Interconnect -p tcp -m tcp --dport 832 -j ACCEPT
-A RH-Firewall-1-INPUT -i Interconnect -p udp -m udp --dport 832 -j ACCEPT
8. Save your changes and exit the file.
9. Set boot-ti me persistence for the yp ser ver services:
# chkconfig --level 2345 ypserv on
# chkconfig --level 2345 ypxfrd on
10. Start the services:
# service ypserv start
# service ypxfrd start
11. Ensure that the master NIS server is responsive:
# ping master_NIS_server_name
12. Create the NIS slave server where master_NIS_server_name is the na
me or IP
address of the master NIS server. The location of the ypinit comman
d differs depending
upon your cluster platform:
• For Opteron or Xeon–based systems, enter:
# /usr/lib64/yp/ypinit -s master NIS_server_name
• For Itanium-based systems, enter:
# /usr/lib/yp/ypinit -s master_NIS_server_name
