3. Click
Submit.
Note:
SSH keys may be created on another computer and uploaded to the XPort Pro.
For example, use the following command using Open SSH to create a 1024-bit DSA key
pair:
ssh-keygen –b 1024 –t dsa
SSH Keys from other programs may be converted to the required XPort Pro format. Use Open
SSH to perform the conversion.
To convert from RFC-4716 format:
ssh-keygen –i
For more options, look at the help from Open SSH:
ssh-keygen ?
1. If the keys do not exist, select the
Key
Type
and the key’s
Bit
Size
from the
Create
New
Keys
section. Click
Submit
to create new private and public host keys.
Note:
Generating new keys with a large bit size results in longer key generation times.
2. Click
SSH >SSH Server: Authorized Users
at the top of the page. The SSH Server:
Authorized Users page appears.
3. Enter the
Username
and
Password
for authorized users.
4. If available: locate the
Public
RSA
Key
or the
Public
DSA
Key
file by clicking
Browse
.
Configuring a public key results in public key authentication; this bypasses password queries.
Note:
When uploading the security keys, ensure the keys are not compromised in
transit.
SSH Server Authorized Users
On this page you can change SSH server settings for Authorized Users. SSH Server Authorized
Users are accounts on the XPort Pro that can be used to log into the XPort Pro using SSH. For
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.
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.
