28 EMC NetWorker Release 8.1 SP1 Installation Guide
Software Requirements
To display non-English textual elements, the dates, the times, and the numbers in the
NMC GUI ensure that you:
◆ Install the appropriate NetWorker language package on the client.
◆ Define the LC_ALL and LANG environment variables to match the NetWorker language
pack installed.
For example, on Solaris:
• To use the French NetWorker language pack, type:
setenv LANG fr
setenv LC_ALL fr
• To use the Japanese NetWorker language pack, type:
setenv LANG ja
setenv LC_ALL ja
• To use the Simplified Chinese NetWorker language pack, type:
setenv LANG zh
setenv LC_ALL zh
• To use the Korean NetWorker language pack, type:
setenv LANG ko
setenv LC_ALL ko
TCP/IP requirements
The NetWorker software requires that you install and configure TCP/IP on each host.
Before you install the NetWorker software, ensure that:
◆ The /etc/hosts file on each Solaris and Linux NetWorker host contains an entry for the
IPv4 loopback address:
127.0.0.1 localhost.localdomain localhost
◆ The NetWorker server when configured as a DHCP client, uses 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 nslookup.
◆ When using OS tools for example, nslookup, the IP address of the host must resolve to
the same hostname defined for the NIC used by NetWorker
◆ The hostname does not contain an underscore character (_).
IPv6 protocol
Internet Protocol version 6 (IPv6) is a next generation Internet protocol used concurrently
with IPv4 or in a pure IPv6 environment. IPv6 increases the number of available IP
addresses and adds improvements in the areas of routing and network autoconfiguration.
IPv6 addresses are represented by 8 groups of 16-bit hexadecimal values that are
separated by colons (:).
