Attributes

The SCP collection agent and the SCP forwarding agent share a number of common attributes. They are both supported by a number of algorithms:

3des-cbc, 3des-ctr, blowfish-cbc, aes128-cbc, aes192-cbc, aes256-cbc, aes128-ctr, aes192-ctr, aes256-ctr, arcfour, arcfour128, arcfour256.

Authentication

The SCP agents support authentication through either username/password or private key. Private keys can optionally be protected by a Key password. Most commonly used private key files, can be imported into .

Typical command line syntax (most systems):

ssh-keygen -t <keyType> -f <directoryPath>



SettingDescription

keyType

The type of key to be generated. Both RSA and DSA key types are supported.

directoryPath

Where to save the generated keys.


Example

The private key may be created using the following command line:

 > ssh-keygen -t rsa -f /tmp/keystore
    Enter passphrase: xxxxxx
    Enter same passphrase again: xxxxxx


Then the following is stated:

Your identification key has been saved in /tmp/keystore
    Your public key has been saved in /tmp/keystore.pub

When the keys are created the private key may be imported to the SCP agent:

Finally, on the SCP server host, append /tmp/keystore.pub to $HOME/.ssh/authorized_keys. If the $HOME/.ssh/authorized_keys is not there it must be created.
