Working with Software Images
RCP requires a client to send a remote username on each RCP request to a server. When you copy an
image from the bridge to a server by using RCP, the Cisco IOS software sends the first valid username
in this list:
The username specified in the archive download-sw or archive upload-sw privileged EXEC
•
command if a username is specified.
The username set by the ip rcmd remote-username username global configuration command if the
•
command is entered.
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 bridge software sends the Telnet username as the remote username.
The bridge host name.
•
For the RCP copy request to execute successfully, an account must be defined on the network server for
the remote username. If the server has a directory structure, the image file is written to or copied from
the directory associated with the remote username on the server. For example, if the image file resides
in the home directory of a user on the server, specify that user's name as the remote username.
Before you begin downloading or uploading an image file by using RCP, do these tasks:
•
Ensure that the workstation acting as the RCP server supports the remote shell (rsh).
•
Ensure that the bridge has a route to the RCP server. The bridge 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 bridge 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 archive operations. The new username is stored
in NVRAM. If you are accessing the bridge through a Telnet session and you have a valid username,
this username is used, and there is no need to set the RCP username. Include the username in the
archive download-sw or archive upload-sw privileged EXEC command if you want to specify a
username only for that operation.
When you upload an image to the RCP to the server, it must be properly configured to accept the
•
RCP write request from the user on the bridge. For UNIX systems, you must add an entry to the
.rhosts file for the remote user on the RCP server. For example, suppose the bridge contains these
configuration lines:
hostname ap1
ip rcmd remote-username User0
If the bridge 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.
