Configuring Secure Shell (SSH)
Terminology
Terminology
SSH Server:
 A ProCurve switch with SSH enabled.
Key Pair:
 A pair of keys generated by the switch or an SSH client 
application. Each pair includes a public key, that can be read by 
anyone and a private key, that is held internally in the switch or by a 
client.
PEM (Privacy Enhanced Mode):
 Refers to an ASCII-formatted 
client public-key that has been encoded for portability and efficiency. 
SSHv2 client public-keys are typically stored in the PEM format. See 
figures 6-3 and 6-4 for examples of PEM-encoded ASCII and non-
encoded ASCII keys.
Private Key:
 An internally generated key used in the authentication 
process. A private key generated by the switch is not accessible for 
viewing or copying. A private key generated by an SSH client applica-
tion is typically stored in a file on the client device and, together with 
its public key counterpart, can be copied and stored on multiple 
devices.
Public Key:
 An internally generated counterpart to a private key. A 
device’s public key is used to authenticate the device to other devices.
Enable Level:
 Manager privileges on the switch.
Login Level:
 Operator privileges on the switch.
Local password or username:
 A Manager-level or Operator-level 
password configured in the switch.
SSH Enabled:
 (1) A public/private key pair has been generated on 
the switch (
crypto key generate ssh [rsa]) and (2) SSH is enabled (ip 
ssh). (You can generate a key pair without enabling SSH, but you 
cannot enable SSH without first generating a key pair. See “2. 
Generate the Switch’s Public and Private Key Pair” on page 6-10 and 
“4. Enable SSH on the Switch and Anticipate SSH Client Contact 
Behavior” on page 6-15.)
