SSH Server Authorized Users

You can change SSH server settings for Authorized Users which are accounts that enable access

to the EDS1100/2100. 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.

To configure the SSH server for authorized users, perform the following steps.

1. Click SSH > Server Authorized Users. Figure 11-2 shows the page that displays.

Create New Keys  Key Type—Select a key type to use for the new key. RSA = use this

key with the 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:

- 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.
