Using the copy Command

Copyright © 2010, Juniper Networks, Inc.
NOTE: The TFTP protocol does not support username and password. Entering
a username and password in the TFTP version results in a command error.
The protocol specified in the command always overrides the protocol associated with
the host entry, if any, in the host table. Some protocols, such as FTP, require a username
and password with each request. For the URL version of the copy command, the following
sequence is followed:
If the command contains a username, the username and password specified in the
command are used. The password null is used if the command does not contain a
password.
If the location in the URL is a hostname with a corresponding host entry (created by
the host command), the username and password of the host entry are used. A host
entry that is created without an explicit user name is created with the default username
of anonymous and password of null.
The location is the IP address or hostname of the remote file server. The directory/filename
is the full path of the file relative to the user login root path.
The characters in the URL format can be encoded. Any of the delimiter characters can
be used in the host, username, password, and directory and file fields when added as
encoded characters. The encoded characters must be three characters, starting with a
percent and followed by the two hexadecimal digits that are the ASCII equivalent. The
system converts all printable characters before passing them to the protocol support.
Unprintable characters (0-012F and 0x7f-0x7F) are not converted and are passed directly
to the protocol. Printable characters (0x20– 0x7E) are decoded and all others
(0x80–0xFF) are rejected.
In the following example, the username contains the @ delimiter character encoded as
%40, and the directory passed to the FTP protocol layer is /dirA/dirB/dirC. The delimiter
between the hostname and directory is a forward slash (/) character. To add a slash to
the start of the directory specification, add the encoded slash after the host and directory
delimiter.
ftp://user%40%40name:pwd@mary/%2fdirA/dirB/dirc/fileA
In the following example, the directory passed to the FTP protocol layer is dirA/dirB/dirC.
ftp://username:pwd@mary/dirA/dirB/dirc/fileA
Table 37 on page 290 shows the types of files that you can transfer between the locations
by using the copy command.
