SSH Server Authorized Users
You can change SSH server settings for Authorized Users which are accounts that enable access
to the XPort AR. For example, these SSH accounts can be used to log into the CLI or open an
SSH connection to a device port. Every account must have a password.
The public keys are optional and only necessary if public key authentication is required. Using
public key authentication allows a connection to be made without a password.
Under Current Configuration, User has a Delete User link, and Public RSA Key and Public DSA
Key have View Key and Delete Keylinks. If you click a Delete link, a message asks whether you
are sure you want to delete this information. Click OK to proceed or Cancel to cancel the
operation.
Create New Keys
Key Type
Select a key type to use.
RSA
—Use this key with SSH1 and SSH2 protocols.
DSA
—Use this key with the SSH2 protocol.
Bit Size
Select a bit length for the new key: 512, 768, 1024. Using a larger bit size
takes more time to generate the key. Approximate times are:
2 minutes for a 512 bit RSA Key
5 minutes for a 768 bit RSA Key
15 minutes for a 1024 bit RSA key
10 minutes for a 512 bit DSA key
30 minutes for a 768 bit DSA key
70 minutes for a 1024 bit DSA key
Note:
Some SSH clients require RSA host keys to be at least 1024 bits
long.
