Authentication; Name Resolution; Protocols; Fixed Ip Address - Dell OpenManage Network Manager Quick Reference Manual

Authentication

For successful discovery of the resources on your network, this software requires authenticated
management access to the device. To get this access, you must provide the correct SNMP community
strings, and any other command-line (Telnet / SSH) or browser (HTTP/HTTPS) authentication, and
SNMP must be turned on, if that is not the device's default. Some devices require pre-configuration to
recognize this management software. Consult your network administrator for this information.

Name Resolution

OpenManage Network Manager server and client require resolution of equipment names to work
completely, whether by host files or domain name system (DNS). The application server cannot
respond to hosts with IP addresses alone. The application server might not even be in the same
network and therefore the host would be unable to connect.
If your network does not have DNS, you can also assign hostnames in
%windir%\system32\drivers\etc\hosts on Windows (/etc/hosts in Linux). Here, you
must assign a hostname in addition to an IP address somewhere in the system. Here are some example
hosts file contents (including two commented lines where you would have to remove the # sign to
make them effective):
# 102.54.94.97
#
127.0.0.1
CAUTION:
This software supports installation only on the local file system. Avoid installing to shared drives.

Protocols

OpenManage Network Manager uses the following protocols: TCP/IP, SNMP, HTTP/S, UDP
Multicast.

Fixed IP Address

OpenManage Network Manager includes a web server and must be installed to a host with a fixed IP
address or a permanently assigned Dynamic Host Control Protocol (DHCP) lease. For trial purposes,
you can rely on a dynamic IP address assignment with a long lease, but this is not recommended for
production installations.
If you do change your host's IP address
To accommodate a changed IP address, first delete the contents of \oware\temp. Change your local
IP address anywhere it appears in
\owareapps\installprops\lib\installed.properties. Then restart your machine.
Alternatively, in a shell, after running oware to set the environment, you can run
ipaddresschange -n followed by the new IP address to which you want to change.
