| Table |
|
|
SSH Client: Users | Description |
Settings |
|
Username | Enter the name that the device uses to connect to a SSH server. |
Password | Enter the password associated with the username. |
Remote Command | Enter the command that can be executed remotely. Default is shell, which tells the |
| SSH server to execute a remote shell upon connection. This command can be |
| changed to anything the remote host can perform. |
Private Key | Enter the name of the existing private key you want to use with this SSH client user. |
| You can either enter the path and name of the key, or use the Browse button to |
| select the key. |
Public Key | Enter the path and name of the existing public key you want to use with this SSH |
| client user or use the Browse button to select the key. |
| Note: If the user public key is known on the remote SSH server, the SSH server |
| does not require a password. The Remote Command is provided to the SSH server |
| upon connection. It specifies the application to execute upon connection. The default |
| is a command shell. |
| Note: Configuring the SSH client’s known hosts is optional. It prevents |
| Middle (MITM) attacks |
Key Type | Select the key type to be used. Choices are: |
| RSA = use this key with the SSH1 and SSH2 protocols. |
| DSA = use this key with the SSH2 protocol. |
Create New Keys |
|
Username | Enter the name of the user associated with the new key. |
Key Type | Select the key type to be used for the new key. Choices are: |
| RSA = use this key with the SSH1 and SSH2 protocols. |
| DSA = use this key with the SSH2 protocol. |
Bit Size | Select the bit length of the new key: |
| 512 |
| 768 |
| 1024 |
| Using a larger Bit Size takes more time to generate the key. Approximate times are: |
| 10 seconds for a 512 bit RSA Key |
| 15 seconds for a 768 bit RSA Key |
| 1 minute for a 1024 bit RSA key |
| 30 seconds for a 512 bit DSA key |
| 1 minute for a 768 bit DSA key |
| 2 minutes for a 1024 bit DSA key |
| Note: Some SSH clients require RSA host keys to be at least 1024 bits long. This |
| device generates keys up to 1024 bits long. It can work with larger keys (up to 2048 |
| bit) if they are imported or otherwise created. |
