You tin can also set the number to infinity with the values 0 or inf, equally in the following example:

          wget --tries=inf http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

Skip Certificate Cheque

The --no-check-certificate option is used to avoid document government checking for a server certificate. However, employ it only if you lot are sure of the website'due south credibility or are not worried about security issues it may cause.

          wget --no-cheque-certificate [URL]

If http://enteratonerisk.com has an untrusted certificate, but will non impairment the system, you tin download it with:

          wget --no-check-certificate http://enteratonerisk.com

When downloading a webpage, wget substantially emulates a browser. In some cases, the output might say you lot don't have permission to access the server, or that the connexion is forbidden. This may exist due to a website blocking client browsers that take a specific "User-Agent."

"User-Amanuensis" is a header field that the browser sends to the server it wants to admission. Therefore, to download from a server that is refusing to connect, try to modify the user agent.

Find a database of all user agents online, search for the ane you need and run the command:

          wget --user-amanuensis="User Agent Here" "[URL]"

or

          wget -U "User Amanuensis Here" "[URL]"

For example, to emulate Chrome (version 74), yous would change the user agent with the control:

          wget --user-agent=" Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36" "https://phoenixnap.com"
