Click the Create button to create a new Endpoint, or select an existing Endpoint and click the Edit button to edit an existing endpoint. Enter the required fields as defined in the table below.

Field Name	Required	Description
Endpoint Name	Yes	The name of the Endpoint.
Description	No	An optional description for the Endpoint.
Active	Yes	Whether or not the endpoint is active in the system. Defaults to "Yes".
Connection Type	Yes	The connection type used for connection to the Endpoint. Currently SSH and localhost are supported.
OS Type	Yes	The operating system of the Endpoint. Unix and Windows are the supported types.
Endpoint Address	Yes	The DNS name or IP address of the Endpoint.
Port	Yes	The SSH port of the Endpoint (typically port 22).
User Name	Yes	The user account on the Endpoint to connect with.
Password	No	The password for the User Name. Either password or Private Key File is required.
Private Key File	No	Fully-qualified path of the SSH private key file. Either Private Key File or Password is required. ~ is not supported here.
Passphrase	No	An optional passphrase used when the private key was generated. Only valid if a Private Key File is specified.
Base Directory	Yes	A working directory on the Endpoint used by FlexDeploy. ~ is not supported here.
Group	No	An optional group identifier which can be useful when searching for Endpoints.
Subgroup	No	An optional subgroup identifier which can be useful when searching for Endpoints.
JDK Home	Yes	The JDK Home directory on the Endpoint.

Optionally, click the Test Connection button to validate that the FlexDeploy server can connect to the configured Endpoint.

Click the Save button to save the changes to the Endpoint.

To inactivate an endpoint select an existing endpoint and click the Inactivate button. The endpoint will not be displayed if the criteria for Active is set to "No". To reactivate an endpoint, select the desired endpoint and click the Edit button. Then change the drop down menu for active to "Yes" and click Save. This endpoint is now active in the system again and ready for use.

SSH Authentication

FlexDeploy utilizes SSH to connect to its configured Endpoints. SSH uses public-key cryptography to authenticate the remote computer and allow it to authenticate the user. FlexDeploy supports Password Authentication and Public-Private Key Authentication.

Password Authentication

The first mechanism is to use automatically generated public-private key pairs to simply encrypt a network connection, and then use password authentication to log on. In this case you must provide a User Name and Password to connect to the endpoint.

Public-Private Key Authentication

The second mechanism is to use a manually generated public-private key pair to perform the authentication, allowing the FlexDeploy server to connect to endpoints without having to specify a password. In this scenario, a public and private key pair are generated on the FlexDeploy server. The private key is kept secretly on the server by setting the permissions such that only the owner can read it (the userid which the FlexDeploy server is running as). The public key is copied to all endpoint computers which must allow access to the owner (user running FlexDeploy server) of the matching private key. While authentication is based on the private key, the key itself is never transferred through the network during authentication. SSH verifies whether the same person offering the public key also owns the matching private key. In this case you must provide the User Name, the path to the Private Key File on the server, and an optional Passphrase (an optional password assigned to the private key when it was generated).

Creating a Public-Private Key Pair

If you do not already have SSH keys generated for the host where FlexDeploy is installed, login (or switch user) as the user which FlexDeploy runs as, and run the following OpenSSH command.

ssh-keygen –t <rsa | dsa> ** where rsa or dsa is the encryption algorithm you wish to use.

Here is the sample output (with interactive prompts) using rsa encryption.

Generating public/private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:

It is typical to use the default file name and location to store the private key (which is in the .ssh subfolder of the user's home directory). You can optionally secure the private key file with a passphrase. It is an SSH requirement that the private key be readable only by its owner (e.g. oracle in the example above). So you must change the permissions accordingly (e.g. chmod 600 /home/oracle/.ssh/id_rsa). You will receive an error at connection time similar to the following if you omit this step.

Permissions 0777 for '/home/oracle/.ssh/id_rsa' are too open.

It is recommended that your private key files are NOT accessible by others.
This private key will be ignored.

The /home/oracle/.ssh folder on the endpoint must have drw------- permissions (eg. chmod 700 /home/oracle/.ssh)

Uploading the Public Key

We must now copy the contents of the public key to each endpoint host. This step can be performed manually by copying the contents of the public key file on the FlexDeploy server and appending it to the end of the following file on the endpoint:

~/.ssh/authorized_keys (Note that you will need to create this file if it does not already exist)

Sample contents of an authorized_keys file (containing two public keys):

The public key can also be copied to the endpoint's authorized_keys file using the Upload Public Key button.

Validate that the derived name and location of the public key is correct, and enter the password for the Endpoint connection user (if not already provided on the Endpoint definition). Click the Upload button to upload the public key to the Endpoint.

Special Note for Oracle Java Cloud Service

The SSH connectivity for the Java Cloud Service is no different than when running on-premise. However, by default you will not know the password for the oracle user. You have two options for configuring endpoints on Java Cloud Service instances.

Using PuTTy, connect to the Java Cloud Service instance VM using the opc user and the private key you generated when you created that instance. Sudo to root and change the oracle password. You can now use this password to configure the endpoint to connect using the oracle user.
Manually copy the public key into the authorized_keys file within the .ssh folder of the oracle home (/u01/app/oracle/tools/paas/state/homes/oracle/.ssh/authorized_keys). You can also use the upload public key feature of FlexDeploy if you know the oracle password (e.g. by following the instructions in #1 above). Once the keys are in place you can configure the endpoint to reference the private key instead of the password.
