Updating hosts file is not working
When an offset larger than the specified maximum occurs, it will be ignored for the specified number of times and then 's tasks is to work out how fast or slow the computer’s clock runs relative to its reference sources.
In addition, it computes an estimate of the error bounds around the estimated value.
FTP has a stateful control connection which maintains a current working directory and other flags, and each transfer requires a secondary connection through which the data are transferred.
In "passive" mode this secondary connection is from client to server, whereas in the default "active" mode this connection is from server to client.
Although users are commonly asked to send their email address instead of a password, FTP normally transfers data by having the server connect back to the client, after the PORT command is sent by the client.
HTTP essentially fixes the bugs in FTP that made it inconvenient to use for many small ephemeral transfers as are typical in web pages.Several proposed standards amend RFC 959, for example RFC 1579 (February 1994) enables Firewall-Friendly FTP (passive mode), RFC 2228 (June 1997) proposes security extensions, RFC 2428 (September 1998) adds support for IPv6 and defines a new type of passive mode.The server responds over the control connection with three-digit status codes in ASCII with an optional text message.The File Transfer Protocol (FTP) is the standard network protocol used for the transfer of computer files between a client and server on a computer network.FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server.
