How to use PPTP?

To use PPTP, you’ll have to set up a PPP session between the server and the client, usually over the internet. Once the session is established, you’ll create a second dial-up session. This dial-up session will use PPTP to dial through the existing PPP session.

What is LCP in PPP?

PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host and specifies PPP client configuration, to communicate between host and PPP client. LCP allows PPP to support authentication negotiation, in addition to compression and encryption negotiation between the client and the server, using encryption control protocols (ECPs) and compression control protocols (CCPs). PPP can support multiple network protocols by using protocol-specific network control protocols (NPCs). Because it can run over numerous physical media types and features error-checking functionalities, PPP has almost entirely replaced SLIP.

How does TFTP work on IP phones?

Most IP phones rely on a TFTP server to download their configuration file after powering on. The configuration file can sometimes contain passwords that can be used to directly connect back to the phone and administer it or used to access other services (such as the company directory). An attacker who is sniffing the file when the phone downloads this configuration file can glean through these passwords and potentially reconfigure and control the IP phone. To thwart this attack vector, vendors variously encrypt the configuration file or use HTTPS and authentication.

What is TFTP protocol?

The Trivial File Transfer Protocol (TFTP) is an Internet-standard protocol for file transfer that uses minimal capability and minimal overhead.

Why does DNS use TCP?

The fundamental reason for this is to keep the latency of DNS lookups as low as possible; using TCP would incur significantly higher latency because of the need to set up and shut down a TCP connection. However, DNS uses TCP to perform zone transfers between D NS servers, as these are effectively the equivalent of a file transfer, and it is vitally important that the data are not corrupted.
