From the Backup Navigator Installation Guide, pg 5
HP Backup Navigator requires port 5555 for access. Opening this port can be accomplished graphically using the Firewall Configuration Wizard (system-config-firewall) or using the command line interface (CLI). An example of the CLI code to open this port is listed below
:
[root@localhost ~]# iptables –I INPUT –p tcp --dpport 5555 –j accept
Alternatively, the iptables file can be edited manually by making changes to the /etc/sysconfig/iptables file. Finally, if a firewall is not required, the firewall can be disabled by running the following commands:
[root@localhost ~]# service iptables save
[root@localhost ~]# service iptables stop
[root@localhost ~]# chkconfig iptables off
This concludes the necessary configuration steps to prepare the RHEL 6.4 operating system to host HP Backup Navigator
==============
So, it appears that you can change to port 8555 by running
iptables –I INPUT –p tcp --dpport 8555–j accept
