If you are writing to the server, the RCP server must be properly configured to accept the RCP write request from the user on the device. For UNIX systems, you must add an entry to the .rhosts file for the remote user on the RCP server. For example, suppose the device contains the following configuration lines: hostname Device1 ip rcmd remote-username User0 If the device IP address translates to device1.example.com, then the .rhosts file for User0 on the RCP server should contain the following line: Device1.example.com Device1 Requirements for the RCP Username The RCP protocol requires a client to send a remote username on each RCP request to a server.
When you copy a configuration file from the device to a server using RCP, the Cisco IOS software sends the first valid username it encounters in the following sequence: 1. The username specified in the copy EXEC command, if a username is specified. 2. The username set by the ip rcmd remote-username global configuration command, if the command is configured. 3. The remote username associated with the current tty (terminal) process. For example, if the user is connected to the device through Telnet and is authenticated through the username command, the device software sends the Telnet username as the remote username. 4. The device host name.
For the RCP copy request to execute, an account must be defined on the network server for the remote username. If the server has a directory structure, the configuration file or image is written to or copied from the directory associated with the remote username on the server. For example, if the system image resides in the home directory of a user on the server, specify that user name as the remote username. Refer to the documentation for your RCP server for more information. Copying a Configuration File from the Device to an FTP Server You can copy a configuration file from the device to an FTP server.
Understanding the FTP Username and Password The password must not contain the special character '@'. If the character '@' is used, the copy fails to parse the IP address of the server. Note 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 device to a server using FTP, the Cisco IOS software sends the first valid username it encounters in the following sequence: 1. The username specified in the copy EXEC command, if a username is specified. 2. The username set by the ip ftp username global configuration command, if the command is configured.
