First you need to open the iptables firewall settings in /etc/sysconfig/iptables.
## NetBackup Client Firewall Ports
iptables -D RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited
iptables -A RH-Firewall-1-INPUT -m state –state NEW -p tcp –dport bpcd-j ACCEPT –src
iptables -A RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited
After you update the config you just need to restart iptables.
/etc/init.d/iptables restart
