Transferring files to Windows systems

To transfer support files to a Windows® system, you use WinSCP. You can download WinSCP from http://winscp.net/eng/download.php.


	NOTE: Other Windows-based SCP utilities are not supported.

To transfer files to a Windows system:

1

Launch WinSCP from your Microsoft® Windows workstation.

The WinSCP Login dialog box opens.

2

To create a new connection, click New and specify the following options:

•

File protocol — Select SCP.

•

Port number — Use the default port number 22.

•

Host name —Type the host name or IP address of the appliance.

•

User name —Type an SSH-enabled Console Program account name.

•

Password — Type the password for the account.

Optional—before connecting to the appliance, save this connection by clicking Save and provide a name under which to save this information.

3

To connect to an appliance, click Login.

4

If this is the first time you are connecting to an appliance, you are notified that the RSA fingerprint cannot be authenticated. Click OK to continue.

The WinSCP file transfer window opens. On the left is your Windows Documents folder. On the right is the /home/<user_account> directory on the appliance, which in this example contains a support bundle file called logfiles.zip.

Optional—navigate to a different directory on your Windows system.

5

Drag the support file from the appliance to the Windows system.

6

To log out of the appliance and close the WinSCP window, click the Close button in the top right corner.

Transferring files to Linux systems

Most UNIX® systems including Linux® comes with a SCP utility called scp. File transfer are one way only — from the appliance to the Linux system.

You must initiate the file transfer from the appliance, not from your Linux system. In other words, you need to push the file from the appliance to the Linux system, rather than using your Linux system to pull the file from the appliance.

To transfer files to Linux systems:

1

Log in to the Console Program on the appliance using an SSH-enabled account.

2

Select Advanced Options.

3

Select Access Shell.

4

Use the following syntax:

scp <file> <Linux_account>@<IP_address>:/home/<Linux_account>/

•

<file> is the support bundle or TCP dump file, such as logfiles.zip.

•

<Linux_account> is the user account name on your Linux system.

•

<IP_address> is the IP address or host name of your Linux system.

Troubleshooting appliance-hosted Management Servers

If you encounter problems with a Management Server on an appliance, contact Dell Support. You may be asked to generate a support bundle as described in Creating support bundles. You may also be instructed on how to start the Management Server in debug mode to gather more information.

Differences from working with server-hosted Management Servers

If you are used to working with server-hosted Management Servers, you should note the following differences for appliance-hosted Management Servers:

•

The appliance.config file enables you to change a subset of the settings found in the server.config file and other Foglight configuration files.

•

You cannot edit the server.config file or other files directly. See Restricted file access.

•

If you need to change other settings, request a hotfix from Dell Support. The settings are restricted to prevent changing options in such a way that the Management Server exceeds the capacity of the appliance.

•

The process for backing up and restoring an appliance-hosted Management Server is different than a server-hosted Management Server. For instructions, see Backing up and restoring physical appliances.
