Telnet protocol Content Extraction
Option Negotiation isTelnetThe most complex part of the Protocol.39Options are used to configure the working mode between the local and remote hosts. When one party wants to execute an option, it needs to send a request to the other end. If the other party accepts this option, the option takes effect at both ends. Otherwise, the two ends maintain the original mode.TelnetCommand Format, such as table2.1, Tab
Telnet runs at the application layer based on the TCP transmission protocol and provides terminal interaction between the client and the server.
Telnet uses a TCP connection. Unlike FTP, two TCP connections are used. The port number used by the telnet server is 23.
Both Parties shall negotiate options during Telnet connection.For example, the size of the window in character mode and the terminal type must be negotiated.Negotiation is implemented through commands supported by Telnet.

2. network virtual terminal (nvt): unified character sets for different systems.
(1) character sets use two types. One is equivalent to the value 0-of ASCII (that is, the value of a bit starting with 0 ).One is the remote control character. The first bit is 1. For example, IAC

1. The essence of the capacitive buck: the discharge of the capacitance, charge and discharge current determines its ability to provide the load current. Generally used in low-cost, small-current scenarios. Load current is available at dozens of Mah. Note that this circuit is unsafe and the 12v voltage is mounted on a 220V voltage. This circuit is half-wave rectified.
2. When the 220v increases from zero, at this time the largest current, increase to 220v when the current is the smallest, and t

Sometimes binary transmission over Telnet is more efficient, which is the root cause. As long as the two parties change the data interpretation method, this option can be completed, so it is more convenient.
