A reverse connection is usually used to bypass firewall restrictions on open ports. [1] A firewall usually blocks incoming connections on closed ports, but does not block outgoing traffic . In a normal forward connection, a client connects to a server through the server's open port , but in the case of a reverse connection, the client opens the ...
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
Telnet consists of two components: (1) the protocol itself and (2) the service component. The telnet protocol is a client-server protocol, based on a reliable connection-oriented transport. [2] This protocol is used to establish a connection to Transmission Control Protocol (TCP) port number 23 or 2323, where a Telnet server application is ...
The main purpose of a router is to connect multiple networks and forward packets destined either for directly attached networks or more remote networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router ...
Each host listens on the mDNS port, 5353, transmitted to a well-known multicast address and resolves requests for the DNS record of its .local hostname (e.g. the A, AAAA, CNAME) to its IP address. When an mDNS client needs to resolve a local hostname to an IP address, it sends a DNS request for that name to the well-known multicast address; the ...
The Windows Remote Desktop Connection client can be used to connect to such a server. There is also Azure Virtual Desktop which makes use of RDP and is a part of the Microsoft Azure platform. There is also a VirtualBox Remote Display Protocol (VRDP) used in the VirtualBox virtual machine implementation by Oracle . [ 43 ]
Many server administrators also use remote administration to control the servers around the world at remote locations. It is also used by companies and corporations to improve overall productivity as well as promote remote work. It may also refer to both legal and illegal (i.e. hacking) remote administration (see Owned and Trojan). [1] [2]
