Image Copying from Flash Memory to an FTP Server

Last Updated: NaN, yyyy

The FTP protocol requires a client to send a remote username and password on each FTP request to a server. When you copy a configuration file from the router to a server using FTP, the Cisco IOS software sends the first valid username it encounters in the following list:

  1. The username specified in the copy privileged EXEC command, if a username is specified.
  2. The username set by the ipftpusername global configuration command, if the command is configured.
  3. Anonymous.

The router sends the first valid password it encounters in the following list:

  1. The password specified in the copy privileged EXEC command, if a password is specified.
  2. The password set by the ipftppassword global configuration command, if the command is configured.

The router forms a password username @routername .domain . The variable username is the username associated with the current session, routername is the configured hostname, and domain is the domain of the router.

The username and password must be associated with an account on the FTP server. If you are writing to the server, the FTP server must be properly configured to accept the FTP write request from the user on the router.

If the server has a directory structure, the configuration file or image is written to or copied from the directory associated with the username on the server. For example, if the system image resides in the home directory of a user on the server, specify that user's name as the remote username.

Refer to the documentation for your FTP server for more information.

Use the ipftpusername and ipftppassword commands to specify a username and password for all copies. Include the username in the copy command if you want to specify a username for that copy operation only.

You can copy a system image from an FTP server to a flash memory file system.

FTP Username and Password

The FTP protocol requires a client to send a remote username and password on each FTP request to a server. When you copy a configuration file from the router to a server using FTP, the Cisco IOS software sends the first valid username it encounters in the following list:

  1. The username specified in the copy privileged EXEC command, if a username is specified.
  2. The username set by the ipftpusername global configuration command, if the command is configured.
  3. Anonymous.

The username and password must be associated with an account on the FTP server. If you are writing to the server, the FTP server must be properly configured to accept the FTP write request from the user on the router.

If the server has a directory structure, the configuration file or image is written to or copied from the directory associated with the username on the server. For example, if the system image resides in the home directory of a user on the server, specify that user's name as the remote username.

Copying an Image from Flash Memory to an FTP Server

Last Updated: NaN, yyyy

To copy a system image to an FTP network server, complete the tasks in this section:

SUMMARY STEPS

1.    enable

2.    configure terminal

3.    ip ftp username username

4.    ip ftp password password

5.    end

6.    show flash-filesystem :

7.    copy flash-filesystem : filename ftp: [[[//[username [:password ]@]location ]/directory ]/filename ]


DETAILED STEPS
  Command or Action Purpose
Step 1
enable


Example:

Router> enable

 

Enables privileged EXEC mode.

  • Enter your password if prompted.
 
Step 2
configure terminal


Example:

Router# configure terminal

 

(Optional) Enters global configuration mode. This step is required only if you override the default remote username or password (see Steps 2 and 3).

 
Step 3
ip ftp username username


Example:

Router(config)# ip ftp username user1

 

(Optional) Changes the default remote username.

 
Step 4
ip ftp password password


Example:

Router(config)# ip ftp password guessme

 

(Optional) Changes the default password.

 
Step 5
end


Example:

Router(config)# end

 

(Optional) Exits global configuration mode. This step is required only if you override the default remote username or password (see Steps 2 and 3).

 
Step 6
show flash-filesystem :


Example:

Router# show flash:

 

(Optional) Displays the system image file in the specified flash directory. If you do not already know it, note the exact spelling of the system image filename in flash memory.

 
Step 7
copy flash-filesystem : filename ftp: [[[//[username [:password ]@]location ]/directory ]/filename ]


Example:

Router# copy slot0:1:your-ios ftp://myuser:mypass@172.23.1.129/dirt/sysadmin/your-ios

 

Copies the image to the FTP server.

Note    After you have issued the copy privileged EXEC command, you may be prompted for additional information or for confirmation of the action. The prompting will depend on how much information you provide in the copy command and the current setting of the fileprompt global configuration command.
 

Examples

The following example uses the showslot1:privilegedEXEC command to display the name of the system image file in the second PCMCIA slot, and copies the file (test) to an FTP server: 

Router# show slot1:
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1   .. 1        46A11866 2036C   4    746      May 16 1995 16:24:37 test
Router# copy slot1:test ftp://thisuser:thatpass@172.16.13.110/test
writing test!!!!...
successful ftp write.

In this example, the file named your-ios is copied from partition 1 of the flash memory PC card in slot 0 to the TFTP server at 172.23.1.129. The file will be saved with the name your-ios in the dirt/sysadmin directory relative to the directory of the remote username. 

Router# show slot0: partition 1
PCMCIA Slot0 flash directory, partition 1:
File  Length   Name/status
  1   1711088 your-ios 
[1711152 bytes used, 2483152 available, 4194304 total]
Router# copy slot0:1:your-ios ftp://myuser:mypass@172.23.1.129/dirt/sysadmin/your-ios
Verifying checksum for 'your-ios' (file # 1)...  OK
Copy 'your-ios' from Flash to server
  as 'dirt/sysadmin/ios-2'? [yes/no] yes
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Upload to server done
