Network requirements
As shown in Figure 128, Router A acts as an SCP client and Router B acts as an SCP server. A user can
securely transfer files with Router B through Router A. Router B uses the password authentication method
and the client's username and password are saved on Router B.

NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Press CTRL+C to abort.
Input the bits of the modulus[default = 1024]:
