Certain Backup vendors are NDMP compatible and they require NDMP port to be free on PORT-10000, sometimes its used by other applications and could cause the Backup failure.
Resolution:
To resolve the issue, it is required to determine the application/service which is using port 10000, and then either free the port or change the NDMP port on the <>\etc\services file and also on the Bakup as well as Agents server. Its most recommended to FREE the ndmp 10000 port.
Follow the steps given below to determine the port usage:
1. On the RedHat Linux system, open the terminal/command line prompt and type the command given below.
Note: There are number of different commands to check the port status. Choose the command you are most comfortable with. This is what i use, for details on basic linux commands see the links on the right.
lsof -i tcp:10000
The figure above shows that port 10000 is listening for the process ID 17923.
The next step is to determine which application is using this process.
2. To determine the application using a given process, type the command shown below.
ps -ax grep 17923
The figure above is showing that an application called "Webmin" is using NDMP port 10000. The Administrator will need to either free the port or change the NDMP port number to be used by Backup Software.
Note: It is recommended to FREE the port instead of changing the NDMP port to be used by Backup Software, because if you opt to change the NDMP port then this change must be made not only to the Backup Server but too all the agents server.
What is Webmin:
Webmin is a web-based interface for system administration for Unix. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing and so on. Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd.
Webmin by default uses the port 10000 when installed.
