// You will given a one-time tunnel. SSH authentication to

// *****************************************************************************
|
|
// * IMPORTANT NOTE: *
|
|
// * *
|
|
// * There are now multiple SSH support hosts. Logging in directly *
|
|
// * is not officially supported behavior, because you may end up on the wrong *
|
|
// * server. A script called 'rs' to use the new format '1.2.3.4;45630' is *
|
|
// * available. Ask your Victron contact to supply you with it. *

// The proxy opened up to the CCGX will be restricted to your IP: 145.40.192.17
|
|
//
|
|
// Commands are:
|
|
// proxyport [port] - take color control [port] and temporarily make it available to the outside.
|
|
// iptoport [ip] - show the ports being listened on by that IP. Note, you do need to know
|
|
// which server the device is connected to. Currently, possibilites are:
|
|
// - 84.22.108.49 (EU)
|
|
// - 84.22.107.120 (EU)
|
|
// - 3.69.217.175 (EU)
|
|
// - 3.72.120.57 (EU)
|
|
// - 3.25.10.245 (AUS Sydney)
|
|
// - 35.165.124.40 (USA West)
|
|
// - 13.244.154.199 (South Africa)
|
|
// - 13.246.113.18 (South Africa)
|
|
// A good start would be the last known, as seen on the diagnostics page.
