Login to the NetBackup Administration Console Failed and Error Message "Can not connect to the NB-Java authentication service via VNETD on linux on port 13724 (status 525)" Is Displayed

Publication Date:  2015-07-28 Views:  45 Downloads:  0
Issue Description
After the NetBackup software is installed on the HDP3500E, login to the NetBackup Administration Console fails. Error message Unable to login, status: 525 Can not connect to the NB-Java authentication service via VNETD on linux on port 13724. is displayed.

Handling Process
1.  Log in to the HDP3500E as the root user.

2.  Check whether the VNETD entry in the /etc/services file and NETD_PORT in the /usr/openv/java/nbj.conf file are consistent.

The default VNETD port number is 13724. If the VNETD entry in the /etc/services file and NETD_PORT in the /usr/openv/java/nbj.conf file are inconsistent, ensure that the port number is consistent.
  • Check the VNETD entry in the /etc/services file.
             more /etc/services | grep vnetd
             vnetd           13724/tcp  # Veritas Network Utility
             vnetd           13724/udp  # Veritas Network Utility
  • Check NETD_PORT in the /usr/openv/java/nbj.conf file.
             more /usr/openv/java/nbj.conf | grep VNETD_PORT
             VNETD_PORT=13724


3.  Check the listening status of the VNETD service.

netstat -a | grep vnetd
  • If no output is displayed, the VNETD service is not properly listened. Perform 4 to listen the VNETD service.
  • If the following output information is displayed, the VNETD service is being listened.
             tcp   0   0 *:vnetd   *:*   LISTEN

4.  Start the xinetd service.

/etc/init.d/xinetd restart

5.  Log in to the NetBackup Administration Console again.
Root Cause
Possible Causes:
The VNETD port is not enabled.

Fault Diagnosis:
NB-Java authentication service is used to authenticate user identity during login. When you log in to the NetBackup Administration Console or the Backup, Archive, and Restore (BAR) console, the system communicates with the NB-Java authentication service to authenticate the user identify. If the VNETD port is not enabled, the communication fails and therefore the login fails.
