The simplest applications are as follows:

SCP Local username @IP address: File name 1 remote user name @IP address: file name 2

[Local User name @IP address:] Can not be entered, you may need to enter the password for the remote user name.

Several parameters that may be useful:

-V is the same as-V in most Linux commands to show progress. Can be used to view connections, certifications, or configuration errors.

-C Enable compression option.

-P Select the port. Note-P has been used by RCP.

-4 forcibly use the IPV4 address.

-6 forcibly use the IPV6 address.

Note two points:
1. If the remote server firewall has special restrictions, the SCP will go to the special port, depending on what port, depending on the situation, the command format is as follows:
#scp-P 4588 [email Protected]:/usr/local/sin.sh/home/administrator
2. Use SCP be aware that the user you are using has permission to read the appropriate files for the remote server.
