tunneling attack

Basic concepts of tunneling tools:1. In a computer network, a tunneling tool is a technique that uses a network protocol to encapsulate another network protocol.2. Usually used for data camouflage or through the firewall, after the intrusion target system, can be used to improve permissions and permissions to maintain.Introduction to Tunneling tools in Kali:(1) d

With the increasing popularity of networks, network security has become a hot topic. This article analyzes the tunneling technology, focuses on the security field, and provides suggestions on using tunneling technology to implement virtual private networks in Linux. VPN is a networking method on the surface, which has many advantages over a leased line network. In VPN, a so-called "Tunnel" technology can b

Cracking Point-to-Point Tunneling Protocol (PPTP) encrypted VPN (1) PPTP (Point to Point Tunneling Protocol) is a Point-to-Point Tunneling Protocol. This protocol is a new enhanced security protocol developed on the basis of the PPP protocol. It supports multi-protocol Virtual Private Network (VPN) and can pass the password verification protocol (PAP) and Extens

How to Do SSH tunneling (port forwarding) In this post we will see how SSH works ?, What is SSH tunneling? What is important of SSH tunnels and how to setup the SSH tunnel.When SSH server is installed in machine then by default its allowed SSH tunneling. SSH tunneling (port forwarding)

With the depletion of IPv4 addresses, IPv6 is necessary for application. However, most networks around the world are still using IPv4, so the transition from IPv6 to IPv4 must be gradual, which is a relatively slow process, in this case, we need to use the IPv6 Tunneling Technology to connect the IPv4 network with the IPv6 network. There are three types of IPv4 and IPv6 Tunneling technologies: DualStack) tu

The network is called a network because of its large system and there are no isolated islands. With the use of IPv6, there is a small island in the network. In order to connect networks of the two protocol versions, we need to use the IPv4/IPv6 Tunneling mechanism to accomplish this arduous task. How can we achieve this? Next we will explain in detail the tunneling technology.

Tunneling and network Virtualization: NVGRE vs VXLAN We believe that the NVGRE and VXLAN tunneling protocols are no stranger, but in fact the Tunneling Protocol is only part of the virtual network. It does not provide substantive functions, but only defines how to encapsulate and forward packets between different virtual machines. This article would like to emph

networks. This number is the same as the number of virtual networks supported by Vxlan. The 8-bit FLOWID enables the hypervisor to perform finer-grained manipulation of different data streams within a single virtual network. Flowid should be generated and added by the Nvgre endpoint (NVE), which does not allow network device modification during network transfer. If Nve does not generate FLOWID, then the domain must be zeroed. In addition, because the Nvgre internally encapsulates an Ethernet fr

I used to have an article about HTTP tunneling, recently in their own server combat, found a problem, because the port 80 to Apache, is not for the Web server and flashcom is the same machine, can not implement HTTP tunneling? Search flashcom Help, about the HTTP tunneling description is very few and die Hu unclear, so directly to see So immediately try to add a

Apsara stack Firewall is a comprehensive product series that covers the business needs of small to large enterprises. Taking the flying tower firewall 310B as an example, it is a product for medium-sized enterprises. It integrates routing (supporting RIP, OSPF, BGP and Multicast), unified Threat Management (UTM), VPN, WAN optimization, Gateway proxy, and wireless control. The Apsara stack firewall supports ipsec vpn and ssl vpn, which have unique configuration and monitoring features. This artic

However, tunnel technology cannot directly communicate with IPv4 hosts and IPv6 hosts.IPv6-over-IPv4 GRE Tunneling TechnologyUsing the standard GRE tunneling technology, IPv6 data packets can be carried over IPv4 GRE tunnels. The GRE tunnel is a connection between two points. Each connection is a separate tunnel. The GRE tunnel uses IPv6 as the passenger protocol and GRE as the bearer protocol

Currently there is a scenario where client A to Server B goes to get an HTTP request, in between a firewall, the firewall to monitor the GET request, if the discovery will be truncated.Here are 2 requirements:1, client A If the packet caught, found that the server is the IP of b2, the server side if turn, found that the connection is client a3, if there is a transit server, can not withstand too much pressureAs a result, a cannot use the normal VPN service to reach B, because after the normal VP

The tunnel technology is used to connect the two networks that are currently used by both protocols, that is, the IPv6 network and IPv4 network, to ensure compatibility. Now let's mainly analyze this technology. Tunneling Technology In the early stages of IPv6 development, there must be many local pure IPv6 networks, which are isolated by IPv4 backbone networks. In order to connect these isolated IPv6 islands, we will adopt the tunnel technology to so

Knowledge Point Analysis: Teredo is an address assignment and inter-host automatic tunneling technology that helps users establish IPV6 unicast connections when Ipv6/ipv4 hosts are located behind one or more IPv4 NAT. IPV6 packets are sent as UDP messages based on IPV4.The exclamation point device "Teredo Tunneling Pseudo-Interface" appears in Device Manager because the operating system does not correctly
