LCP tests the link between client and PPP host ...
How to use PPTP?
To use PPTP, you set up a PPP session between the client and server, typically over the Internet. Once the session is established, you create a second dial-up session that dials through the existing PPP session, using PPTP. The PPTP session tunnels through the existing PPP connection , creating a secure session.

On the downside, high overhead is associated with using PPP, and it is not compatible with some older configurations. From the technician’s standpoint, PPP is easy to configure. Once you connect to a router using PPP, the router assigns all other TCP/IP parameters.
What is SMB protocol?
The Server Message Block (SMB) protocol is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. The SMB protocol can be used on top of its TCP/IP protocol or other network protocols. Using the SMB protocol, an application (or the user of an application) can access files or other resources at a remote server. This allows applications to read, create, and update files on the remote server. SMB can also communicate with any server program that is set up to receive an SMB client request. SMB is a fabric protocol that is used by Software-defined Data Center (SDDC) computing technologies, such as Storage Spaces Direct, Storage Replica. For more information, see Windows Server software-defined datacenter.

To help make sense of all the protocol configuration options involved in setting up remote access servers, take a look at the categories of protocols and the advantages and disadvantages of the various protocols within each one.
What are the two methods of remote access?
First, you need to consider two distinct methods of remote access, each of which uses different protocols: Dial-up. Virtual private networking (VPN) Within each method, there are three basic categories for protocols: Connectivity. Authentication.
What protocol is used for dial up encryption?
For data encryption in a dial-up session in a Windows network. In order to use MPPE, the authentication protocol for the dial-up session must be either EAP-TLS or MS-CHAP version 1 or 2. VPN protocols.
What is virtual private network?
Virtual private networking protocols encapsulate PPP frames (the data units at the data link layer of the OSI model) into IP datagrams at the network layer. These datagrams are then sent across an internetwork, which can be either a private network or, more commonly, the Internet. This encapsulation creates a “tunnel” that acts like a dedicated WAN link, even though it usually uses the Internet—thus, a “virtual” private network.
Why do you want to be encrypted in a remote session?
First, you want the best security you can provide for the remote session. You want authentication to be encrypted so that someone who is snooping cannot see it , and you want the data that is passed in the remote session to be encrypted for the same reason. Second, older systems and their associated protocols are less capable in terms ...
What is dial up modem?
Dial-up involves one modem connecting with another over the Public Switched Telephone Network (PSTN), creating a temporary, dedicated WAN link. There are three possible protocols for making the initial connection: Point-to-Point Protocol (PPP), Serial Line Internet Protocol (SLIP), and Asynchronous NetBEUI (AsyBEUI). Table A explains their differences.
How does dial up authentication work?
Authenticating the user. Part of the dial-up process involves authentication, usually by providing a password. Since that password can be intercepted and used to gain unauthorized access, it should be encrypted using the strongest possible method that is supported by both the server and the client.
What is RDP protocol?
This article describes the Remote Desktop Protocol (RDP) that's used for communication between the Terminal Server and the Terminal Server Client. RDP is encapsulated and encrypted within TCP.
Why is RDP used in Windows NT?
One reason that Microsoft decided to implement RDP for connectivity purposes within Windows NT Terminal Server is that it provides an extensible base to build many more capabilities. RDP provides 64,000 separate channels for data transmission. However, current transmission activities are only using a single channel (for keyboard, mouse, ...
Why use RDP?
One of the key points for application developers is that, in using RDP, Microsoft has abstracted away the complexities of dealing with the protocol stack. It allows them to write clean, well-designed, well-behaved 32-bit applications. Then the RDP stack implemented by the Terminal Server and its client connections takes care of the rest.
How does RDP work?
Data from an application or service to be transmitted is passed down through the protocol stacks. It's sectioned, directed to a channel (through MCS), encrypted, wrapped, framed, packaged onto the network protocol, and finally addressed and sent over the wire to the client. The returned data works the same way only in reverse. The packet is stripped of its address, then unwrapped, decrypted, and so on. Finally the data is presented to the application for use. Key portions of the protocol stack modifications occur between the fourth and seventh layers, where the data is:
What is RDP in Microsoft?
highly encrypted data, such as keyboard, mouse activity. RDP is an extension of the core T.Share protocol. Several other capabilities are retained as part of the RDP, such as the architectural features necessary to support multipoint (multiparty sessions).
What is RDP in computer?
However, current transmission activities are only using a single channel (for keyboard, mouse, and presentation data). RDP is designed to support many different types of Network topologies, such as ISDN, POTS. RDP is also designed to support many LAN protocols, such as IPX, NetBIOS, TCP/IP.
Does RDP support TCP/IP?
RDP is also designed to support many LAN protocols, such as IPX, NetBIOS, TCP/IP. The current version of RDP will only run over TCP/IP. With customer feedback, other protocol support may be added in future versions.
Why is ARP not required?
ARP isn't required every time devices attempt to communicate because the LAN's host stores the translated addresses in its ARP cache, so this process is mainly used when new devices join the network.
How many protocols are there in the network?
To get started, this glossary explores 12 common network protocols all network engineers should be familiar with. This includes the protocols' main functions, as well as why these common network protocols are important.
What is BGP in LAN?
Border Gateway Protocol. BGP makes the internet work. This routing protocol controls how packets pass through routers in an autonomous system (AS) -- one or multiple networks run by a single organization or provider -- and connect to different networks. BGP can connect endpoints on a LAN to one another, and it can connect endpoints in different LANs to one another over the internet.
What is OSPF first?
Open Shortest Path First. OSPF works with IP in sending packets to their destinations. IP aims to send packets on the quickest route possible, which OSPF is designed to accomplish. OSPF opens the shortest, or quickest, path first for packets. It also updates routing tables -- a set of rules that control where packets travel -- and alerts routers of changes to the routing table or network when a change occurs.
What is external BGP?
External BGP directs network traffic from various ASes to the internet and vice versa. Additionally, internal BGP directs network traffic between endpoints within a single AS.
How does IP work?
IP functions similarly to a postal service. When users send and receive data from their device, the data gets spliced into packets, which are like letters with two IP addresses: one for the sender and one for the recipient. After the packet leaves the sender, it goes to a gateway, like a post office, that directs it in the proper direction. Packets continue to travel through gateways until they reach their destinations.
What is HTTPS in security?
Another form of HTTP is HTTPS, which stands for HTTP over Secure Sockets Layer or HTTP Secure . HTTPS can encrypt a user's HTTP requests and webpages. This provides more security to users and can prevent common cybersecurity threats, such as man-in-the-middle attacks.
