Remote SSH Connections

For OS login, it is recommended to use passphrase protected SSH key pairs instead of passwords, and to not allow remote root login. To do this, take the following steps:

• Generate a passphrase-protected SSH key for each system that needs to access the server.
• Disable SSH password authentication.
• Disable root login.

Zixi Feeders, Zixi Broadcasters and Zixi Receivers have a section under Settings that enables you to define reverse tunnels to a remote SSH server, in order to allow accessing the application through a secure SSH tunnel remotely. Make sure to stop/delete all tunnels if remote access is not desirable.

 To configure an SSH Tunnel in Zixi Feeder/Receiver:

1. Go to Settings > SSH Tunnels.
2. In the Server Connection section configure the server connection, as described in the table below.
   
3. Click Apply.
4. In the Reverse tunnels section, click Add.
   The Tunnel details dialog appears:
   
5. In the Remote Source Port field, type the Remote Source Port that will be used to connect.
6. In the Local Destination IP field, type the IP address of the Zixi Feeder/Receiver.
7. In the Local Destination Port field, type the port number in the Zixi Feeder/Receiver for the specific reverse SSH tunnel.
8. Click OK.
