Lisa Compact 75
17 Network and internet
17.1 Configure the network settings
Configuration of the network settings can be done using the Lisa Configuration Tool.
To configure the network settings of the Lisa with the Lisa Configuration Tool, use the help presented in
the tool.
17.2 Using a proxy server
The Lisa supports the use of HTTP proxy servers. To make the Lisa work with an HTTP proxy server,
two steps are required:
·
Programming the proxy server URL into the Lisa
·
Enabling the use of the proxy server on the Lisa
By separating both steps, it is possible to prepare the Lisa for a proxy server in one network (e.g. your
office) and to enable the use of the proxy server when the Lisa is placed in the target network where the
proxy server should be used.
17.2.1
Programming the proxy server URL into the Lisa
The proxy server URL can be programmed using the respective command (see Command overview list )
using the Lisa Configuration Tool . Alternatively, the proxy server URL can be defined in the Device
portal and loaded into the Lisa through a configuration update .
17.2.2
Enabling the use of the proxy server
The use of a proxy server can be enabled using the respective command (see Command overview list )
via one of the methods available to send commands to the Lisa (see Commands ).
17.2.3
Proxy server with authentication
The Lisa only supports basic authentication with the proxy server. For basic authentication, the
username and password are added as part of the proxy URL which is programmed in the device (e.g.
http://username:pass@server:port) . See HTTP Basic Authentication for more information how basic
authentication is supported by the Lisa.
Other authentication protocols, such as NTLM (Microsoft proprietary) are not supported. You can find
out whether you are dealing with a server requiring NTLM authentication, by investigating the Lisa
Configuration Tool logs. When the device tries to connect, the proxy server will respond with HTTP error
407. The HTTP response also contains a header indicating the type of authentication protocol used.
Below, part of a HTTP proxy response, requiring NTLM:
HTTP/1.0 407 Proxy Authorization Required
Proxy-Authenticate: Negotiate
Proxy-Authenticate: NTLM
