With the popularization of linux applications, linux management is increasingly dependent on remote management. Putty is one of the most outstanding telnet tools.
I. Introduction to Putty
Putty is a free and small Win32 platform telnet, rlogin and ssh client. Its main program is only 364 KB, but its functions are not inferior to commercial telnet tools.
