SSH Tunneling is supported with the
direct property. By default,
direct is set to
false. When set to
true, the property indicates the
Connection will be made directly to a TE (instead of to a broker). This enables a connection string to be set up in a third party tool, for example, DBVisualizer, on a tunnel you have set up to a specific TE.
The syntax for setting up a JDBC connection to an SSH tunnel is:
To find the TE's host and port, use the show domain summary command in NuoDB Manager.
nuodbmgr --brokerNuoDB host version: 3.0: Professional Edition nuodb [domain] >
show domain summaryHosts: [broker] * ip-172-31-40-24/18.104.22.168:48004 (us-east-1) Database: test, (umnanaged) processes [1 TE, 1 SM], ACTIVE [SM] ip-172-31-40-24/22.214.171.124:48006 (us-east-1) [ pid = 32594 ] [ nodeId = 1 ] RUNNING [TE] ip-172-31-40-24/126.96.36.199:48007 (us-east-1) [ pid = 32611 ] [ nodeId = 2 ] RUNNING
The JDBC URL can then be constructed using the TE's port.
Multiple TEs can be specified in the JDBC URL as follows:
ssh command allows you to establish a tunnel into a remote machine and to execute commands on that remote machine.
In this example, a direct tunnel is established between a local machine (
localhost) and a target Amazon EC2 NuoDB TE instance, going from port 48005 on
localhost to an open port, 48010, of the EC2 host (188.8.131.52) as user
ssh -L 48005:localhost:48010 email@example.com
In this example, an Amazon EC2 instance acts as the jump server (
ec2-54-224-133-82.compute-1.amazonaws.com, with user
ec2-user. The jump server opens an SSH connection to a known host, 184.108.40.206 (
Host B), that has an open port on 48010 and creates a port locally on port 48005.
# ssh -L 48005:<Host B>:48010 ec2-user@<Host A> $
ssh -L 48005:220.127.116.11:48010 firstname.lastname@example.org
