Working with Configuration Files
• The remote username associated with the current TTY (terminal) process. For example, if the user
is connected to the router through Telnet and was authenticated through the username command,
the WMIC software sends the Telnet username as the remote username.
• The WMIC hostname.
For a successful RCP copy request, you must define an account on the network server for the remote
username. If the server has a directory structure, the configuration file is written to or copied from the
directory associated with the remote username on the server. For example, if the configuration file is in
the home directory of a user on the server, specify that user's name as the remote username.

Preparing to Download or Upload a Configuration File by Using RCP
Before you begin downloading or uploading a configuration file by using RCP, perform these tasks:
• Ensure that the workstation acting as the RCP server supports the remote shell (rsh).
• Ensure that the WMIC has a route to the RCP server. The WMIC and the server must be in the same
subnetwork if you do not have a router to route traffic between subnets. Check connectivity to the
RCP server by using the ping command.
• If you are accessing the WMIC through a Telnet session and you do not have a valid username, make
sure that the current RCP username is the one that you want to use for the RCP download. You can
enter the show users privileged EXEC command to view the valid username. If you do not want to
use this username, create a new RCP username by using the ip rcmd remote-username username
global configuration command to be used during all copy operations. The new username is stored in
NVRAM. If you are accessing the WMIC through a Telnet session and you have a valid username,
this username is used, and you do not need to set the RCP username. Include the username in the
copy command if you want to specify a username for only that copy operation.
• When you upload a file to the RCP server, it must be properly configured to accept the RCP write
request from the user on the WMIC. For UNIX systems, you must add an entry to the .rhosts file for
the remote user on the RCP server. For example, suppose that the WMIC contains these
configuration lines:
hostname ap1
ip rcmd remote-username User0
If the WMIC IP address translates to ap1.company.com, the .rhosts file for User0 on the RCP server
should contain this line:
ap1.company.com ap1
For more information, refer to the documentation for your RCP server.
Downloading a Configuration File by Using RCP
