CentOS to prohibit users ssh and SFTP login
In Linux for security purposes, we will prohibit certain users SSH login system to operate. Here I take the CentOS operating system as an example to record how to do the processing.
1, open the sshd configuration file

Vi/etc/ssh/sshd_config
2, modify the configuration file, add or modify such as downlink

Configure SSH, sftp, telnet, and other services-Linux Enterprise Application-Linux server application information. For more information, see the following section. The ssh and telnet services are both remote logon control servers and cannot be uploaded or downloaded;
To enable the ssh service, run:/etc/init. d/sshd start on the terminal to close and run:/etc/init. d/sshd stop to enable the telnet service.
Run vi/etc/xinetd on the terminal. d/telnet

Use SFTP to manage files on Raspberry Pi
SFTP (SSH File Transfer Protocol) is a network protocol that provides SSH-based file access, file transfer, and file management methods.
With SFTP, you can easily modify, browse, and edit files on Raspberry Pi. SFTP is easier to configure than FTP, because Raspbian has enabled

From http://www.cnblogs.com/chen1987lei/archive/2010/11/26/1888391.htmlSFTP is an interactive file transfer program. It is similar to FTP, but it is encrypted and has higher security than FTP. Below is a brief introduction of how to connect the host remotely, file upload and download, and some related operations.For example, if the remote host IP is 202.206.64.33 or domain name www.hebust.edu.cn, the user name is Fyt, in the command line mode: SFTP [e

Is that the user uses the HTTPS protocol to upload files to the primary Linux server, and then the primary server uses the NFS protocol to transfer files to another storage server. The reason for this is that it is more secure and users cannot access the storage server directly.But why not use the SFTP protocol to upload users ' files? There are 2 reasons:1. FTP is a file transfer protocol and is highly efficient, even though
Linux under FTP+SSL implementation FTPSFTPs and SFTP:FTPs is the use of SSL protocol encryption, SSL is designed for HTTP/SMTP and other encryption, SFTP is encrypted with SSH, SSH is for TELNET/FTP encryption, establish a transmission channel design. SSH establishes the transmission channel for encryption and transmission, and this channel can be used for remote login. Creates an encrypted channel to encrypt the file.From the principle of simple: FTP
