Firmware download troubleshooting
H
Firmware download using SCP/SFTP does not
work because of one of the following issues:
•
For internal SCP/SFTP server, the
application was uninstalled and
reinstalled without migration
•
For external SCP/SFTP server, the SSH
handshake keypair is changed
-
manually
-
due to an external server reinstall
-
due to the SCP/SFTP server
preference (Options dialog box)
being changed from built-in to
external (installed on same machine)
or vice versa
Clear the SSH (SCP/SFTP) server IP address or hostname from the known_hosts table of
the device.
•
For Fabric OS devices, use the following command:
sw0:FID128:admin> sshutil delknownhost
IP Address/Hostname to be deleted: SSH_server_IP_address
where SSH_server_IP_address is the IP address of the SSH server you want to
delete.
•
For Network OS devices running firmware version 3.0 and later, use the following
command:
sw0# clear ssh-key SSH_server_IP_address
where SSH_server_IP_address is the IP address of the SSH server you want to
delete.
•
For Network OS devices running firmware version 2.1.1b, use the following
command:
sw0# execute-script sshdeleteknownhost
IP Address/Hostname to be deleted: SSH_server_IP_address
where SSH_server_IP_address is the IP address of the SSH server you want to
delete.
Firmware download using an external SCP
server does not work after reinstalling the
application or the external SCP server on the
Host machine. Clear the SCP server IP address or hostname from the known_hosts table of the device
using the following command:
sw0# FID10:root> ssh-keygen –R Host_Name
where Host_Name is the IP address or host name of the external SCP server.
