Error in Firewall Configuration File for Veritas NetBackup Causes Communication Failure Between Veritas NetBackup and Service Console

Details

While configuring Veritas NetBackup for backup/restore operations, the NetBackup server attempts to communicate with the service console and returns the following error:

Unable to connect to Netbackup host "10.17.138.104"

Solution

This message is due to a typo in the services.xml configuration file. This error has been corrected in ESX Server 3.0.2 and higher.
 
If you are using a version of ESX Server earlier than 3.0.2, two workarounds exist to fix this problem.
First Workaround

  1. Open the services.xml configuration file located in the /etc/vmware/firewall directory.

  2. Make the following changes:

    341 <service id='0021'>
    342 <id>veritasNetBackup</id>
    343 <rule id='0000'>
    344 <direction>inbound</direction>
    345 <protocol>tcp</protocol>
    346 <port type='dst'>13724</port> # Change the port from 13734 to 13724
    347 <flags>-m state --state NEW</flags>
    348 </rule>

  3. At the command prompt, run esxcfg-firewall -e veritasNetBackup to activate the modified firewall rule.

Second Workaround

Use the following commands to open the ports:

esxcfg-firewall -o 13724,tcp,in,VerNB
esxcfg-firewall -o 13724,tcp,out,VerNB
