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 thenslookup
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
