In Python, you can use the SFTP in the Paramiko module to login to the remote host for upload and download functions.

The previous article described the use of Jsch to achieve file upload function, this article mainly about the Jsch implementation of file download function. and introduce some auxiliary methods of SFTP, such as Cd,ls and so on.Similarly, Jsch file download also supports three modes of transmission: OVERWRITE, resume and Append, please refer to the previous essay: Jsch-java implementation of SFTP (file uploa
sends it to the client software. After the client software receives a "challenge", you can decrypt it and send it to the server with your private key.
Compared to SSH1, SSH2 does not need to transmit user passwords over the network. In addition, SSH2 not only encrypts all the transmitted data, but the "middleman" attack is impossible (because he doesn't have your private key). However, the entire login process may be slower.
SSH's most common application is to replace the traditional telnet,
Why both SVN and SFTP are introduced. The actual development is to modify their own set of code on the server, when the determination of the same time, only use SVN to submit code, so that the rest of the team can update the code. The usual practice is: the server on the code download to the local, and then through a variety of editors to modify the code, then through an FTP software upload local code to the server, and then refresh the browser to see

Build sftp with openssh in linux (including note) and opensshsftp
To build sftp, three parts are required: zlib (including zlib, zlib-devel), openssl, and openssh. The required rpm packages are available in csdn.

1) Support for SFTP protocol2) do not use the System Account Verification Method. Instead, use the MySQL database for verification.3) No Password is saved in the database. Only the 16-bit lowercase string that has been encrypted by the sha256 algorithm can be printed. A salt file must be saved in the system.4) Specify the user directory in the database, and ProFTPD can dynamically create User DirectoriesModify the SSH service port number to 21

FTP is a client software for one-pass file transfer or upload/download. SSH is a secure remote management protocol, including a file transfer function similar to FTP, that is, SFTP, which is very useful.The most convenient software is winscp.However, if you do not use this function, you can use FlashXP directly. This software also supports this SFTPThe usage of FTP is the same as that of FTP.Select SFTP in
