TCP/IP Requirements

The following requirements are checked when submitting a NetWorker client Connectivity request (How-to check NetWorker client connectivity for UTORrecover )

  •  The NetWorker serverclient, when configured as a DHCP client, must use a reserved address that is synchronized with DNS.
  •  The name of the host that the hostname command returns on the system must match the name that the IP address resolves to when using the nslookup command.
  •  Forward and reverse DNS lookups for the host are successful.
  •  OS tools, for example, the nslookup command, must resolve the IP address of the host to the same hostname that you defined for the NIC that NetWorker uses.
  •  The hostname must not contain an underscore character (_).

Linux

  •  (Optional) Adding the NetWorker Servers listed in "UTORrecover NetWorker Backup Server IPs" to the hosts file on your server, /etc/hosts on *nix based systems, will increase backup speeds by reducing DNS queries.
  •  The /etc/hosts file on each Solaris and Linux NetWorker host must contain an entry for the IPv4 loopback address and the hostname. For example, on Linux the /etc/hosts file contains the following entries by default: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4.The recommended value is `127.0.0.1 hostname hostname.domain localhost
  •  (Optional) Adding the NetWorker Servers listed in "UTORrecover NetWorker Backup Server IPs" to the hosts file on your server, /etc/hosts on *nix based systems, will increase backup speeds by reducing DNS queries.

On a Linux NetWorker Server, the NetWorker daemons cannot start when the IP address 127.0.0.1 is inaccessible on the loopback interface. This requirement is true even in an IPv6-only environment
