OSD Operation

Login String
The Login String allows the KVMs IP address to be more secure by
adding extra text to the end of it. When text is entered into the Login
String field, users will need to include a forward slash (/) and the
Login String at the end of the URL to access the KVM switch. For
example, if a Login String of abcdefg is entered, the user must enter a
URL such as 192.168.0.126/abcdefg.
The following characters are allowed in the login string:
0 through 9, a through z, A through Z, ~ ! @$^&*()_+'<>,.|
The following characters are not allowed:
%":/?#\[Space]
Note: If a Login String is not entered, anyone can access the KVM
switch using the IP Adress alone, making the installation less secure.
Account Policy
The Account Policy section allows rules for usernames and passwords to be regulated. The settings in this section are described in the table

Encryption
This section allows you to set different encryption settings for the Keyboard/Mouse, Video and Virtual Media functions of the KVM switch. You
can choose any combination of encryption methods (DES, 3DES, AES and/or RC4), you can choose to randomly switch between them or you can
choose no encryption at all. Although enabling encryption will add more security to you installation, it can also slow down system performance
(mouse, keyboard, video), with the following having the most impact:
• RC4 impacts performance the least out of the four encryption methods. DES is second to least in impact, followed by 3DES and AES.
• Of all the possible combinations, a combination of RC4 and DES impacts performance the least.

Description
Sets the minimum number of characters required for each username. Values from 1 to 16 can be entered.
Sets the minimum number of characters required for each password. Values can be from 0 to 16.
• One Upper Case – Checking this box will require that each password contain one upper case letter
• One Lower Case – Checking this box will require that each password contain one lower case letter
• One Number – Checking this box will require that each password contain one number
Note: Current usernames and passwords are not affected when these settings are changed. Only usernames and
passwords that are created after these settings have been changed must follow the rules.
Checking this box will prevent users from logging in with the same username and password to open more than one
session at the same time.
Checking this box will require users to create a unique password that does not match the last (x) number of
passwords used prior.
MAC Filtering
To add a MAC filter:
1. Click Add. A dialog box similar to the one below appears:
2. Type in the desired MAC address and click OK.
3. Repeat these steps for any additional MAC addresses you want to
filter.
To delete a MAC filter:
Select the desired MAC filter from the list and click Remove.
To modify a MAC filter:
1. Select the desired MAC filter from the list and click Edit. An Edit
dialog box box appears.
2. Delete the old address and replace it with the new one. Click OK.
Note: To block a computer from accessing the B064-Series KVM
Switch, you do not need to filter both its IP address and its MAC
address. Any computer blocked by a MAC filter will be denied access
to the KVM switch, even if the computer is allowed to access the
KVM switch under the IP filters that are set up.
If any filters have been configured, they appear in the IP Filter and/or
MAC Filter list boxes.
