SSH Client: Users
Settings
Description
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 Man-In-The-
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.
