Security: SSH Client : Overview : Common Tasks
 
Common Tasks
This section describes some common tasks performed by the device as a SSH client. All pages referenced are pages found under the SSH Client branch of the menu tree.
Workflow1: To configure SSH client and transfer data to/from a remote SSH server, perform the following steps:
STEP 1 Decide which method is to be used: password or public/private key. Use the SSH User Authentication page.
STEP 2 If the password method was selected, perform the following steps:
a. Create a global password in the SSH User Authentication page, or create a temporary one in the Firmware Operations or File Operations pages, when you actually activate the secure data transfer.
b. Upgrade the firmware, boot image or language file, using SCP, by selecting the SCP option in the Firmware Operations page. The password can be entered in this page directly, or the password entered in the SSH User Authentication page can be used.
c. Download/backup the configuration file, using SCP, by selecting the via SCP (over SSH) option in the File Operations page. The password can be entered in this page directly, or the password entered in the SSH User Authentication page can be used.
STEP 3 Set up a username/password or modify the password on the remote SSH server. This activity depends on the server and is not described here.
STEP 4 If the public/private key method is being used, perform the following steps:
a. Select whether to use an RSA or DSA key, create a username and then generate the public/private keys.
b. View the generated key by clicking the Details button, and transfer the username and public key to the SSH server. This action depends on the server and is not described in this guide.
c. Upgrade/backup the firmware, using SCP, by selecting the SCP option in the Firmware Operations page.
d. Download/backup the configuration file, using SCP, by selecting the SCP option in the File Operations page.
Workflow2: To import the public/private keys from one device to another:
STEP 1 Generate a public/private key in theSSH User Authentication page.
STEP 2 Set the SSD properties and create a new local passphrase in the SSD Properties page.
STEP 3 Click Details to view the generated, encrypted keys, and copy them (including the Begin and End footers) from the Details page to an external device. Copy the public and private keys separately.
STEP 4 Log on to another device and open the SSH User Authentication page. Select the type of key required and click Edit. Paste in the public/private keys.
STEP 5 Click Apply to copy the public/private keys onto the second device.
Workflow3: To change your password on an SSH server:
STEP 1 Identify the server in the Change User Password on the SSH Server page.
STEP 2 Enter the new password.
STEP 3 Click Apply.
Workflow4: To define a trusted server:
STEP 1 Enable SSH server authentication in the SSH Server Authentication page.
STEP 2 Click Add to add a new server and enter its identifying information.
STEP 3 Click Apply to add the server to the Trusted SSH Servers table.
