Mapping between the IP address and host name

Dear Phany,

You can follow this procedure:

1. Log in to a backup server as an administrator and modify the /etc/hosts file on the backup server. Then add the backup IP address and host name of the storage system.
   For example: 10.169.60.47 and nas01 are the logical port IP address and host name of the storage system, respectively. 10.169.108.240 and nbu-lyp are the IP address of the backup server and host name, respectively.

   
   

   
   

   nbu-lyp:~ # vi /etc/hosts
   
   
   #
   # hosts         This file describes a number of hostname-to-address
   #               mappings for the TCP/IP subsystem.  It is mostly
   #               used at boot time, when no name servers are running.
   #               On small systems, this file can be used instead of a
   #               "named" name server.
   # Syntax:
   #
   # IP-Address  Full-Qualified-Hostname  Short-Hostname
   #
   
   10.0.0.1       localhost
   
   # special IPv6 addresses
   ::1             localhost ipv6-localhost ipv6-loopback
   
   fe00::0         ipv6-localnet
   
   ff00::0         ipv6-mcastprefix
   ff02::1         ipv6-allnodes
   ff02::2         ipv6-allrouters
   ff02::3         ipv6-allhosts
   10.169.60.47         nas0110.169.108.240       nbu-lyp
   
   nbu-lyp:~ # vi /etc/hosts

   ff02::3         ipv6-allhosts
   10.169.60.47         nas0110.169.108.240       nbu-lyp

2. On the backup server, run telnet host name 10000. If the connection is successful, the configuration is correct.
   

   
   

   host name indicates the host name of NDMP.

   10000 indicates the port number of NDMP.

   
   

   nbu-lyp:~ # telnet nas01 10000 

   Trying 10.169.60.47... 

   Connected to nas01. 

   Escape character is '^]'. 

   ^] 

   telnet> quit 

   Connection closed.  

Thank you.

Hope it can help:

1. Log in to a backup server as an administrator and modify the /etc/hosts file on the backup server. Then add the backup IP address and host name of the storage system.
2. On the backup server, run telnet host name 10000. If the connection is successful, the configuration is correct.
host name indicates the host name of NDMP.
10000 indicates the port number of NDMP.
