SCP Agents Attributes and Authentication
- Kevin Wu
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 the system.
Typical command line syntax (most systems):
ssh-keygen -t <keyType> -f <directoryPath>Argument | Description |
|---|---|
| The type of key to be generated. Both RSA and DSA key types are supported. |
| 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:
Edit Private Key dialog
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.
