User Authentication
SCP Protocol Support
In addition to data transfer via an SSH session, the SSH protocol is also used to
support SCP for secure file transfer. When using SCP, the P330 is the client, and an
SCP server must be installed on the management station. After defining users on the
SCP server, the device acts as an SCP client.
The procedure described in the "Introduction to SSH" on page 46 is used with the
roles of the P330 and the client computer reversed.
To accomplish secured transfers, a P330 launches a local SSH client via the CLI in
order to establish a secured channel to the secured file server. The P330
authenticates itself to the server by providing a user name and password. With a
Windows-based SSH server (WinSSHD), the user name provided must be a defined
user on the Windows machine with read/write privileges. The files transferred via
SCP are saved in the "C:\Documents and Settings\username" directory.
The network element performs file transfer in unattended mode.
The P330 doesn't block SCP traffic from users not on the allowed managers list,
because it is the SSH client. In addition, the P330 doesn't prompt the user to
accept the Server's fingerprint nor warns the user if the fingerprint from an IP
address has changed.
For information on SCP file transfer commands, refer to "Uploading and
Downloading Device Configurations and Images"on page 63.
