Black Box MPSH8-D20-208+V, MPSH8-S20-208+V, MPSH16-D20-208+V, Outlet Managed PDU manual Configuration

CHAPTER 5: Configuration

The IP Security configuration menus include "hosts.allow" and "hosts.deny" client lists. When setting up IP Security, you must enter IP addresses for hosts that you wish to allow in the Allow list, and addresses for hosts that you wish to deny in the Deny list. Since Linux operators, wild cards and net/mask pairs are allowed, these lists can indicate specific addresses, or a range of addresses to be allowed or denied.

When the IP Security feature is properly enabled, and a client attempts to connect, the Outlet Managed PDU will perform the following checks:

1.If the client’s IP address is found in the "hosts.allow" list, the client will be granted immediate access. Once an IP address is found in the Allow list, the Outlet Managed PDU will not check the Deny list, and will assume you wish to allow that address to connect.

2.If the client’s IP address is not found in the Allow list, the Outlet Managed PDU will then proceed to check the Deny list.

3.If the client’s IP Address is found in the Deny list, the client will not be allowed to connect.

4.If the client’s IP Address is not found in the Deny list, the client will be allowed to connect, even if the address was not found in the Allow list.

Notes:

•If the Outlet Managed PDU finds an IP Address in the Allow list, it will not check the Deny list, and will allow the client to connect.

•If both the Allow and Deny lists are left blank, then the IP Security feature will be disabled, and all IP Addresses will be allowed to connect (providing that the proper password and/or SSH key is supplied.)

•When the Allow and Deny lists are defined, the user is only allowed to specify the Client List; the Daemon List and Shell Command cannot be defined.
