However, I prefer to get back to the basics and always strive to somehow find a direct URL to the PDF file to then download it via curl or wget. At the same time, it also stores the HTTP cookie s set by the web server when accessing named web page. These cookies are then re-used when accessing the PDF file directly. This has reproducibly worked for me. If it does not work for you, I recommend having a look into the file pdfurl and see if that part of the process has lead to a meaningful result or not.
Step 5. Step 6. Upload the latest firmware file from your TFTP folder to the switch by entering the following:. Step 8. Optional To verify that the new image file has been successfully loaded, check your switch firmware information again by entering the following:. Step 9.
Check the firmware information. The page should show both the old and new image files but should indicate that the old image file will be inactive after reboot and the new image file will be active after reboot. Step Check the image information displayed.
It should now show that the active image is the latest version. The -r flag downloads recursively, meaning it checks the location and then all folders and subfolders within it. The -A flag specifies a comma-separated list of extensions to grab, excluding all other files.
The -R flag works in opposite fashion, specifying extensions to reject but grabbing everything else. Specify a list of files to download using the -i switch. Start by creating a regular text file with a list of downloads, one full URL per line.
Use wget to download all the files using the following command:. The trouble with downloading files from the internet is that sometimes the file or URL is unavailable. The timeout for the connection can take a while, and if you are trying to download lots of files, it is counterproductive to wait for the default timeout.
Specify your own timeout the amount of time the system waits for a file to begin, in seconds using the following syntax:. The above command stops the download of files wgen megabytes has been reached. You can also specify the quota in bytes use b instead of m or kilobytes use k instead of m.
You may not have a download limit but you might have a slow internet connection. To download files without devouring all the available bandwidth on your connection, specify a limit that sets a maximum download rate. The above command limits the download rate to 20 kilobytes per second. Specify the amount in bytes, kilobytes or megabytes. Use wget -c to continue a download where you had left off—a tool useful, for example, with dropped connections.
