The Control Center's CLI applet supports the use of a SOCKS Proxy server when accessing Lantronix devices. Setting up a SOCKS Proxy allows users to access devices through a proxy to bypass routing and firewall limitations and configure proxy servers for groups and/or individual devices.
A properly configured SOCKS Proxy server is required to use this feature. Lantronix Control Centers come pre-installed with the SS5 SOCKS Proxy Server. See SS5 SOCKS Proxy to configure this service.
Both SOCKS Proxy Version 4 and 5 are supported.
SS5 uses version 5 (with authentication)
The IP address of the SOCKS Proxy Server. Do not use 127.0.0.1 or localhost. The client computer must be able to route to the SOCKS IP address.
The listening port of the Socks Proxy Server. Typical default port is 1080.
If you configured the Control Center's SS5 proxy as described in SS5 SOCKS Proxy, the port will be 9000.
Username to authenticate with the proxy server, if required.
Password to authenticate with the proxy server, if required.
Proxy settings can be configured at the global, group, or individual device level.
In this example, the Control Center will be configured to use a socks proxy server with the following configuration:
When the Proxy Version is set to disabled, the configuration options will be grayed out. To begin configuring settings, change the Proxy Version to either 4 or 5.
Once you have configured necessary settings, click Save.
The Socks Proxy configuration will be transparent to the end user. To test your settings, select a previously inaccessible device from the Inventory and launch the SSH applet. A connection to the device should succeed.
If the connection fails, verify that your settings are correct by examining the configuration of the proxy server or by testing with an SSH client such as Putty or SecureCRT.
