Example of Using SCP to Copy from an SSH Server on Another Switch
Other SSH-related commands include:
• crypto key generate: generate keys for the SSH server.
• debug ip ssh: enables collecting SSH debug information.
• ip scp topdir: identify a location for files used in secure copy transfer.
• ip ssh authentication-retries: configure the maximum number of attempts that should be
used to authenticate a user.
• ip ssh connection-rate-limit: configure the maximum number of incoming SSH connections
per minute.
• ip ssh hostbased-authentication enable: enable host-based authentication for the SSHv2
server.
• ip ssh key-size: configure the size of the server-generated RSA SSHv1 key.
• ip ssh password-authentication enable: enable password authentication for the SSH server.
• ip ssh pub-key-file: specify the file the host-based authentication uses.
• ip ssh rhostsfile: specify the rhost file the host-based authorization uses.
• ip ssh rsa-authentication enable: enable RSA authentication for the SSHv2 server.
• ip ssh rsa-authentication: add keys for the RSA authentication.
• show crypto: display the public part of the SSH host-keys.
• show ip ssh client-pub-keys: display the client public keys used in host-based authentication.
• show ip ssh rsa-authentication: display the authorized-keys for the RSA authentication.
• ssh-peer-rpm: open an SSH connection to the peer RPM.
The following example shows the use of SCP and SSH to copy a software image from one switch running
SSH server on UDP port 99 to the local switch.
Dell#copy scp: flash:
Address or name of remote host []: 10.10.10.1
Port number of the server [22]: 99
Source file name []: test.cfg
User name to login remote host: admin
Password to login remote host:
Secure Shell Authentication
Secure Shell (SSH) is disabled by default.
Enable SSH using the ip ssh server enable command.
SSH supports three methods of authentication:
• Enabling SSH Authentication by Password
• Using RSA Authentication of SSH
