Using SDT Connector for out-of-band connection to the gateway
SDT Connector can also be set up to connect to the console server (gateway) out-of-band (OOB). OOB
access uses an alternate path for connecting to the gateway to that used for regular data traffic. OOB
access is useful for when the primary link into the gateway is unavailable or unreliable.
A gateway's primary link is a broadband Internet connection or Internet connection via a LAN or VPN, and
the secondary out-of-band connectivity is provided by a dial-up or wireless modem attached to the
gateway. Out-of-band access enables you to access the hosts and serial devices on the network, diagnose
any connectivity issues, and restore the gateway's primary link.
In SDT Connector, OOB access is configured by providing the secondary IP address of the gateway and
telling SDT Connector how to start and stop the OOB connection. Starting an OOB connection may be
achieved by initiating a dial up connection or adding an alternate route to the gateway. SDT Connector
allows for maximum flexibility is this regard, by allowing you to provide your own scripts or commands for
starting and stopping the OOB connection.
To configure SDT Connector for OOB access:
1.
When adding a new gateway or editing an existing gateway select the
Out Of Band
tab
2.
Enter the secondary, OOB IP address of the gateway (e.g. the IP address it is accessible using
when dialed in directly). You also may modify the gateway's SSH port if it's not using the default of
22
3.
Enter the command or path to a script to start the OOB connection in
Start Command
§
To initiate a pre-configured dial-up connection under Windows, use the following Start
Command:
cmd /c start "Starting Out of Band Connection" /wait /min rasdial network_connection login
password
where network_connection is the name of the network connection as displayed in Control
Panel > Network Connections, login is the dial-in username, and password is the dial-in
password for the connection.
