Editor to share with you the use of linux's ssh command to securely connect to the client. I hope you will gain a lot after reading this article. Let's discuss it together.

Ssh command is a client connection tool in openssh suite, which can give ssh encryption protocol to achieve secure remote login to the server and achieve remote management of the server.

Syntax format: ssh [parameters] [remote host]

Common parameters:

-1 enforce the use of ssh protocol version 1-2 force the use of ssh protocol version 2-4 force the use of IPv4 address-6 force the use of IPv6 address-A turn on authentication agent connection forwarding function-a turn off authentication agent connection forwarding function-b use the address specified locally as the source IP address of the bit connection-C request to compress all data-F specify the configuration file of the ssh instruction The default configuration file is "/ etc/ssh/ssh_config"-f background execution ssh instruction-g allows the remote host to connect to the local forwarding port-I specify the identity file (that is, the private key file)-l specify the login user name to connect to the remote server-N does not execute the remote instruction-o specify configuration option-p specify the port on the remote server-Q silent mode All warnings and diagnostics are disabled-X turns on X11 forwarding-x turns off X11 forwarding-y turns on trust X11 forwarding

Reference example

Log in to the remote server:

[root@linuxcool ~] # ssh 202.102.240.88

Connect to the remote server with a test user:

[root@linuxcool] # ssh-l test 202.102.220.88

View the list of partitions:

[root@linuxcool] # ssh 202.102.220.88 / sbin/fdisk-l

Force the use of ssh protocol version 1:

[root@linuxcool ~] # ssh-1

Enable the authentication agent connection forwarding function:

[root@linuxcool] # ssh-An after reading this article, I believe you have some understanding of the secure connection client using the ssh command of linux. Want to know more about it. Welcome to follow the industry information channel. Thank you for reading!
