What is the default login port number of sftp in linux?

1, sftp uses sshd port 2, netstat-ntlp checks port open state 3, and so does scp.

What is the command for Linux to upload files to the server?

1ssh $ ssh username @ remotehost uses shh to log in to the server.

2. The scp command is based on SSH protocol, and SCP can copy local files to the specified directory on the remote service. The format is as follows: $ scp filename username @ remotehost: remote directory execution: $ scp ipmsg. logadadmin @10.25.1.202:/home/admin3ftp/sftp first log in to the remote Linux server as root, and add a line to the user_list file through the echo command:

# echoadmin & gt& gt After user_list, open FTP service through service command:

# servicevstpdstart can now access the FTP remote server locally, and then upload files through the put command. 4SSHWindowsClientSSH provides a scp2.exe as an scp command tool under Windows.

The server rejected the SFTP connection. Why? The server refused?

Read a lot, no problem. The most important thing is to ensure that sftp (generally/etc/ssh/sshd _ config) is defined in the configuration file of sshd: subsystems FTP/usr/libexec/OpenSSH/SFTP-server, and then start (or restart) the SSHD service. By default, linux systems have SSHD services. Generally, there will be no problem here. I stared at WinSCP for a long time, and suddenly it occurred to me that the server port is not 22(WinSCP is 22 by default), so I can change the port. This is a very simple question. If you start to follow the steps step by step, you can skip the port.

What's the difference between linuxscp, ftp and sftp? Which transfers files faster?

SFTP = FTP+SSSSCP = Secure Copy (Remote File Copy Program), which is brought by openssh. FTP is definitely the fastest encryption speed, because there is no encryption; Sftp and scp should be similar.
