These are the primary remote access protocols that are in use today:
- Serial Line Internet Protocol (SLIP)
- Point-to-Point Protocol (PPP) and Point-to-Point Protocol over Ethernet (PPPoE)
- Point-to-Point Tunneling Protocol (PPTP)
- Remote Access Services (RAS)
- Remote Desktop Protocol (RDP)
What are the different types of remote access protocols?
The primary remote access protocols in use today are the Serial Line Internet Protocol (SLIP), Point-to-Point Protocol (PPP), Point-to-Point Protocol over Ethernet (PPPoE), Point-to-Point Tunneling Protocol (PPTP), Remote Access Services (RAS), and Remote Desktop Protocol (RDP).
What is remote access protocol (rap)?
A remote access protocol manages the connection between a remote computer and a remote access server. These are the primary remote access protocols that are in use today: In 1984, students at the University of California, Berkeley, developed SLIP for UNIX as a way to transmit TCP/IP over serial connections (such as modem connections over POTS).
How do I connect to a remote access server without a script?
If you don’t use a script, you’ll need to establish the connection and then open a terminal window so you can manually log in to the remote access server. PPP is a remote access protocol that allows you to implement TCP/IP. It establishes a connection via point-to-point links (i.e., dedicated leased lines and dial-up).
What is Remote Desktop Protocol (RDP)?
The Remote Desktop Protocol (RDP) is very similar to the Independent Computing Architecture (ICA) protocol used by Citrix products. As a matter of fact, RDP is used to access Windows Terminal Services, a close relative of the Citrix WinFrame product line. RDP performs the same basic functions as ICA, but it does it with a lot less functionality.
Which remote access protocol is used over an Ethernet network Ras PPPoE slip PPP?
Which remote access protocol is used over an Ethernet network? - When PPP Is used over an Ethernet network (no matter that connection type), is known as PPPoE (PPP over Ethernet).
Which encryption protocol does GRE use?
Which encryption protocol does GRE use to increase the security of its transmissions? GRE (generic Routing Encapsulation) uses IPsec for security when transmitting.
Which remote file access protocol is an extension of SSH?
SFTPThe remote file access protocol is an extension of SSH known as SFTP (SSH File Transfer Protocol), and is the most widely used file transfer protocol that runs over SSH.
Which remote access protocol is an earlier protocol that does not support encryption can carry only IP packets and works strictly on serial connections?
SLIP is an earlier Point-to-Point Protocol that does not support encryption, can carry only IP packets, and works strictly on serial connections.
What is IPSec over GRE?
IPSec over GRE technology uses GRE to encapsulate packets that have been encapsulated using IPSec. IPSec over GRE implements IPSec encryption on tunnel interfaces. The system detects data flows that need to be encrypted on tunnel interfaces (an ACL is configured to match data flows between two user network segments).
What is the difference between IPSec and GRE tunnel?
IPsec provides more comprehensive security for IP tunneling, while GRE tunnels work well when network teams need to tunnel with multiple protocols or multicast. Generic Routing Encapsulation, or GRE, and IPsec both encase packets, but the two protocols have different requirements...
Is SSH and SFTP same?
Secure Shell (SSH) creates a secure connection when you log in to a remote computer. Secure File Transfer Protocol (SFTP) uses SSH and provides a secure way to transfer files between computers.
What is SSH used for?
SSH or Secure Shell is a network communication protocol that enables two computers to communicate (c.f http or hypertext transfer protocol, which is the protocol used to transfer hypertext such as web pages) and share data.
How does SSH protocol work?
SSH protocol uses public key cryptography to authenticate the server, meaning the server sends its public key to the client for confirmation. The client is able to authenticate the server by comparing this host key against a local database or by receiving the verification of a Certified Authority (CA).
Which protocol is used for remote access?
The Remote Desktop Protocol (RDP) is a protocol, or technical standard, for using a desktop computer remotely. Remote desktop software can use several different protocols, including RDP, Independent Computing Architecture (ICA), and virtual network computing (VNC), but RDP is the most commonly used protocol.
Which protocol would be best to access the remote network devices?
REMOTE DESKTOP PROTOCOL (RDP)
Which protocol is used for encrypted remote access to a server?
IPsec. Internet Protocol security (IPsec) can be used as a remote access tunneling protocol to encrypt traffic going over the Internet.
Does GRE have encryption?
Generic Routing Encapsulation (GRE) is used when IP packets need to be sent from one network to another, without being parsed or treated like IP packets by any intervening routers. However, they are not secure, does not provide encryption.
Is GRE tunnel encrypted?
A GRE tunnel functions like a VPN but without the encryption; it transports packets from one endpoint to another through the public network. GRE tunnels typically use keepalive packets to determine if a tunnel is up.
What type of protocol is GRE CCNA?
GRE is a Cisco developed protocol which is one of many tunneling protocols. While it is a Cisco developed protocol, it is also defined in several RFCs (1701, 1702 and 2784). GRE encapsulation supports any OSI Layer 3 protocol.
Does GRE use UDP?

What is a RAS modem?
Both Windows NT and Windows 2000 include technology to allow users to dial up a server and connect to not only that server, but also to that server’s host network. This technology is known as RAS. RAS is used in smaller networks where a dedicated dial-up router is not practical or possible. In a RAS setup, you can basically connect a modem to a Windows NT or Windows 2000 server and, by way of the RAS, configure that modem as dial-out only, dial-up only, or a combination.
What is PPTP in a network?
PPTP is the Microsoft-created protocol based on PPP. It is used to create virtual connections across the Internet using TCP/IP and PPP so that two networks can use the Internet as their WAN link and yet retain private network security. PPTP is both simple and secure.
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.
What is RDP in Citrix?
Remote Desktop Protocol (RDP) The Remote Desktop Protocol (RDP) is very similar to the Independent Computing Architecture (ICA) protocol used by Citrix products. As a matter of fact, RDP is used to access Windows Terminal Services, a close relative of the Citrix WinFrame product line.
What is PPP used for?
PPP is used to implement TCP/IP; it is the protocol that establishes a connection over point-to point links (for example, dial-up and dedicated leased lines). It is most commonly used for remote connections to ISPs and LANs.
What is the difference between ICA and RDP?
RDP provides remote access for Windows clients only , whereas ICA provides it for multiple platforms, including DOS, Linux, Macintosh and many others. ICA is also a much more full-featured platform, including support for automatic client updates, publishing an application to a web browser, and much more.
Does PPP use IPCP?
In addition, PPP can automatically configure TCP/IP and other protocol parameters through the use of the IP control protocol (IPCP) NCP. 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.

Point-To-Point Protocol
- PPP is a remote access protocol that allows you to implement TCP/IP. It establishes a connection via point-to-point links (i.e., dedicated leased lines and dial-up). PPP is used most often for remote connections to LANs and ISPs. PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host and specifies PPP client configuration, to communicate between h…
Windows Remote Access Services
- Windows 2000 and Windows NT let users dial up a server and connect to both the server and the server’s host network. This is referred to as RAS, which is used in smaller networks where a dedicated dial-up router would not be possible or practical. With a RAS setup, you can connect a modem to a Windows 2000 or Windows NT server and configure the modem as dial-out only, di…
