Master Connection

Master Connection is the page on the managed server. Trust is granted here, not taken by the master: the server decides which masters may manage it, from which IP addresses, and how much they may do.

What the page shows

• The address masters use to reach this panel, its host name and protocol version.
• Create Link Code, with an optional label. See Add a server.
• Codes waiting to be used, each with its label, creation time and remaining time, and a Cancel button.
• Connected master panels, with each master's allowed IP addresses, key, permission level, last use and connection date.
• Disconnected masters, kept as history.

Permission levels

Use Allow full management or Limit on a master's row to change its level. Opening this server's pages inside the master window requires Full management; with Limited, the master opens them in this server's own panel instead.

Allowed IP addresses

A master's key is accepted only from its allowed IP addresses. Use Edit IPs when the master panel moves to a new address; enter one address per line.

Disconnecting a master

Disconnect stops the master's key immediately; the master can no longer manage this server. To connect again, create a new link code.

License

Being managed by a master needs a Professional, Business or Enterprise license on this server. If the license no longer includes it, connected masters cannot reach the server until the license is upgraded; the page says so.
