Update Cisco DCNM to 11.3(1) due to security Vulnerabilities

Because of Cisco DCNM security issues (see below), just update DCNM to 11.3(1).  Update should be done ASAP.

I am not using the appliance and it is running on Windows with version 11.1(1).  It is running with Oracle Express 11g and managing only MDS FC switches.  We don't use advance features like SAN Insight and it is a standalone Windows server.  Upgrade step is pretty straight forward.

Setting up PuppyLinux on my Raspberry

Just receive my Raspberry pi 4 with 4GB of memory.  Decide to install Raspup 8.2 on it.  Details instructions can be found in Raspup page.

I copy the Windows instructions below.

  1. Download Raspup image from the Downloads page and check the checksum.
  2. Extract the image file from the downloaded .zip file, so you now have "raspup-XXXXXX.img".
  3. Insert the SD card into your SD card reader and check what drive letter it was assigned. You can easily see the drive letter (for example G:) by looking in the left column of Windows Explorer. You can use the SD Card slot (if you have one) or a cheap Adapter in a USB slot.
  4. Download the Win32DiskImager utility (it is also a zip file). You can run this from a USB drive.
  5. Extract the executable from the zip file and run the Win32DiskImager utility; you may need to run the utility as Administrator! Right-click on the file, and select 'Run as Administrator'
  6. Select the image file you extracted above.
  7. Select the drive letter of the SD card in the device box. Be careful to select the correct drive; if you get the wrong one you can destroy your data on the computer's hard disk! If you are using an SD Card slot in your computer (if you have one) and can't see the drive in the Win32DiskImager window, try using a cheap Adapter in a USB slot.
  8. Click Write and wait for the write to complete.
  9. Exit the imager and eject the SD card.
  10. You are now ready to plug the card into your Raspberry Pi.
  11. In Windows, the SD card will appear only to have a fairly small size once written - about 512 MB. This is because most of the card has a partition that is formatted for the Linux operating system that the Raspberry Pi uses which is not visible in Windows. If you don't see this small directory with files such as kernel.img then the copy may not have worked correctly.

PuppyLinux is my favourite Linux and it is a nice desktop for my dad to browse the net.

To read Chinese, just install package fonts_arphic_uming.  
To create Shortcut, go to /usr/share/applications and drag the icon to the Desktop.
