How to Setup Reseller Private Nameservers in WHM
First we need to register the name servers before we set them up on the server.
Resellers can also have their own private name servers for their own clients making the server provider more anonymous.
Login to your WHM account as root.
Click on Reseller Center on the left hand side.
Under Edit Reseller Privileges/Nameservers, select the reseller account you want to provide with private name servers.
Scroll down to the very bottom of the page until you see: Primary Nameserver.
In the Primary Nameserver field enter the primary nameserver.
Click “Assign IP Address”
Click “Add an A Entry for this nameserver”
In the Secondary Nameserver field enter the secondary.
Click Save
Enabling User/Group Quota for virtual private server that already exists.
If the virtual private server already exists, run the following command to set the parameter:
vzctl set 101 –quotaugidlimit 150 –save
Where, 101 is the VPS ID number.
Restart the virtual private server.
Virtual Private Networks (VPNs)
VPNs allow for secured digital communication between two parties (or networks), creating a Wide Area Network (WAN) from existing Local Area Networks (LANs). Where it differs from frame relay or ATM is in its transport medium. VPNs transmit over IP using datagrams as the transport layer, making it a secure conduit through the Internet to an intended destination. Most free software VPN implementations incorporate open standard encryption methods to further mask data in transit.

There are several vendors with hardware VPN solutions such as Cisco, Nortel, IBM, and Checkpoint. There is a free software-based VPN solution for Linux called FreeS/Wan that utilizes a standardized IPsec (or Internet Protocol Security) implementation. These VPN solutions, regardless if hardware or software based, act as specialized routers that sit between the IP connection from one office to another.
When a packet is transmitted from a client, it sends it through the router or gateway, which then adds header information for routing and authentication called the Authentication Header (AH). The data is encrypted and is enclosed with decryption and handling instruction called the Encapsulating Security Payload (ESP). The receiving VPN router strips the header information, decrypts the data, and routes it to its intended destination (either a workstation or node on a network). Using a network-to-network connection, the receiving node on the local network receives the packets decrypted and ready for processing. The encryption/decryption process in a network-to-network VPN connection is transparent to a local node.
Because they employ several layers of authentication and encryption, VPNs are a secure and effective means to connect multiple remote nodes to act as a unified Intranet.
