PSCP.exe - Esempi vari - seconda parte

To receive (a) file(s) from a remote server:

pscp [options] [user@]host:source target

So to copy the file /etc/hosts from the server example.com as user fred to the file c:\temp\example-hosts.txt, you would type:

pscp fred@example.com:/etc/hosts c:\temp\example-hosts.txt

To send (a) file(s) to a remote server:

pscp [options] source [source...] [user@]host:target

So to copy the local file c:\documents\foo.txt to the server example.com as user fred to the file /tmp/foo you would type:

pscp c:\documents\foo.txt fred@example.com:/tmp/foo

You can use wildcards to transfer multiple files in either direction, like this:

pscp c:\documents\*.doc fred@example.com:docfiles
pscp fred@example.com:source/*.c c:\source

However, in the second case (using a wildcard for multiple remote files) you may see a warning saying something like ‘warning: remote host tried to write to a file called 'terminal.c' when we requested a file called '*.c'. If this is a wildcard, consider upgrading to SSH 2 or using the '-unsafe' option. Renaming of this file has been disallowed’.

This is due to a fundamental insecurity in the old-style SCP protocol: the client sends the wildcard string (*.c) to the server, and the server sends back a sequence of file names that match the wildcard pattern. However, there is nothing to stop the server sending back a different pattern and writing over one of your other files: if you request *.c, the server might send back the file name AUTOEXEC.BAT and install a virus for you. Since the wildcard matching rules are decided by the server, the client cannot reliably verify that the filenames sent back match the pattern.
