Dealing with any network barriers to communicating with OpenManage Network Manager, any
required initial device configuration to accept management, and managing security measures or
firewalls—all are outside the scope of these instructions. Consult with your network administrator
to ensure this software has access to the devices you want to manage with the Protocols described
below.

device responds, it is connected to the network. If not, consult your network administrator to correct this.
No useful information comes from disconnected or powered-down devices.
Name Resolution
OpenManage Network Manager server requires 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
# 38.25.63.10
127.0.0.1
Protocols
OpenManage Network Manager uses the following protocols: TCP/IP, SNMP, HTTP/S, UDP
Multicast.

than lose those changes if and when you upgrade your application, best practice is to override
changes. To do this, first change the provided file \oware\synergy\conf\server-
overrides.properties.sample to server-overrides.properties, and enable the
properties within it by uncommenting them, and altering them to fit your needs. The comments in
this file provide more information.
You can also override application server-related properties in
\owareapps\installprops\lib\installed.properties.
