Using the copy Command

Table 36 shows the types of files that you can transfer between the locations by using the copy command.

Table 36: File Types You Can Transfer Using the copy Command copy copycopy

To transfer files using the copy command between the system space and a network host:

1. Determine whether there is a route to the network host, and create one if necessary. See JUNOSe IP, IPv6, and IGP Configuration Guide.
2. Configure the network host as an FTP server, or use a remote host that is configured as a TFTP server.

   Note: This command takes place in the context of the current virtual router (VR) rather than the default VR. You must configure the FTP server so that any traffic destined for the VR can reach the VR; typically, you configure the FTP server to reach the default address of the E-series router, which will always be able to reach the VR.

3. Add the FTP server to the static host table, and specify the file transport protocol (FTP or TFTP), so that the E-series router can access the network host.
4. (Optional) Specify a source interface to use in FTP packets leaving the router.
5. Copy the files.

copy

• Use to copy a file from one location to another.

  Note: You cannot copy script (.scr) or macro (.mac) files while in Boot mode. You can copy only .cnf, .hty, and .rel files. If you issue the dir command from Boot mode, existing .scr and .mac files are not displayed.

• See Table 36 for the types of files that you can copy.
• Specify a network path to copy to or from another device on the network.
• Specify the incoming or outgoing directory to copy to or from the user space.
• Specify a subdirectory name to create a subdirectory within the incoming or outgoing directory in the user space.
• You cannot use wildcards.
• You cannot create or copy over files generated by the system; however, you can copy such files to an unreserved filename.
• Examples

  host1#copy host1:westford.cnf boston.cnf

  host1#copy /incoming/releases/2-8-0a3-7.rel 2-8-0a3-7.rel

  host1#copy /shconfig.txt ftp://joe:passwd@173.28.32.156/ftpDir
  /results/shConfigJoe.txt

• There is no no version.
• See copy.

host

• Use to add or modify an entry to the host table. You can enter the optional username and password in plain text (unencrypted). Or, if you know the correct encrypted forms of the username and password, you can enter the encrypted forms (see below).
• This command supports both IPv4 and IPv6 address formats.
• This command allows network files to be accessible from a host.
• This command supports both FTP and TFTP for copying and redirecting files.
• You cannot invent an encrypted string to be used with the algorithm 8 option. You must use plain text (unencrypted) strings for the initial configuration. The only way to obtain a valid encrypted string is to enable password encryption (by issuing the service password-encryption command) and then examine the output of the show configuration command. Username and password encryption is made available primarily so that scripts generated from the show configuration output can be saved, used, and transferred without fear of password exposure.
• Example

  host1(config)#host westford 10.10.8.7 ftp user25 easy53

• To determine the encrypted values for usernames and passwords entered in cleartext, you must do the following:
  1. Issue the service password-encryption command. This causes subsequently issued show configuration commands to generate encrypted forms of the username and password for this command, as well as for all other commands that support encryption. See Managing the System , for more information about the service password-encryption command.
  2. Issue the show configuration command and search for the host command. The encrypted forms are preceded by the number 8.
  3. You can copy and paste the command showing the encrypted forms into a macro or script to use as desired. Specify the number 8 before the username and before the password to enter an encrypted value.
• Example for encrypted values

  host1(config)#service password-encryption

  host1(config)#host test 10.2.3.4 ftp nick nick

  host1(config)#end

  host1#show config | inc host

  hostname "host1"

  host test 10.2.3.4 ftp 8 CU&l,XM(S 8 X=emZn>'S

• Use the no version to remove a specified host.
• See host.

ip ftp source-address

• Use to specify an operational interface by IP address as the source interface for FTP packets sent by the system’s FTP client.
• This command overrides a setting you configured previously with the ip ftp source-interface command.
• If you issue this command, the output of the show configuration command includes an entry of the following format:

  ip ftp source-address ipAddress

  This entry also appears in the output if you delete an interface or change its IP address after issuing the ip ftp source-interface command, in which case the IP address is the one that was configured on the interface before you issued the ip ftp source-interface command.

• Example

  host1(config)#ip ftp source-address 10.10.5.21

• Use the no version to restore the default, in which the source address in the FTP packets is that of the interface where the FTP connection is made.
• See ip ftp source-address.

ip ftp source-interface

• Use to specify an operational interface by interface type and location as the source interface for FTP packets sent by the system’s FTP client.
• The interface you specify must have an IP address.
• This command overrides a setting you configured previously with the ip ftp source-address command.
• If you issue this command and the interface is valid, the output of the show configuration command includes an entry of the following format:

  ip ftp source-interface interfaceType interfaceSpecifier

  • interfaceType—Type of interface
  • interfaceSpecifier—Location of the interface

    For information about interface types and specifiers, see Interface Types and Specifiers.

• If you delete the interface or change its IP address, the output of the show configuration command appears as if you had entered the ip ftp source-address command:

  ip ftp source-address ipAddress

  • ipAddress—IP address of the interface when you issued the ip ftp source-interface command
• Example

  host1(config)#ip ftp source-interface loopback1

• Use the no version to restore the default, in which the source address in the FTP packets is that of the interface where the FTP connection is made.
• See ip ftp source-interface.
