Create folders for their files:

The best way to download a website for offline use, using wget

There are two ways - the first way is just one command run plainly in front of you; the second one runs in the background and in a different instance so you can get out of your ssh session and it will continue.

First make a folder to download the websites to and begin your downloading: (note if downloading www.SOME_WEBSITE.com, you will get a folder like this: /websitedl/www.SOME_WEBSITE.com/)

STEP 1:

gnilchee

#!/usr/bin/env python3
import sys, os, socket
from socketserver import ThreadingMixIn
from http.server import SimpleHTTPRequestHandler, HTTPServer

HOST = socket.gethostname()

class ThreadingSimpleServer(ThreadingMixIn, HTTPServer):
    pass

NOTE: Given its current state, I've given up on tigervnc and now rely on "ssh -X" to execute remote gui apps. As a result I won't be updating this gist any more, but will leave it up as a reference for others.

Installing TigerVNC on Ubuntu 18.04 LTS

This is for Ubuntu 18.04 LTS. TigerVNC is a remote desktop session server and viewer solution sponsored by Red Hat that is still in active development. While I recently tested under Ubuntu 19.10, I have no plans to test non-LTS versions in the future.

There are packages for TigerVNC in the repositories of the major distributions, but the latest versions for Ubuntu are broken. My workaround is to use the latest stable version from the TigerVNC project Github release page, where generic binaries for 32 and 64-bit Linux are distributed as tarballs (dmg and exe installers for Mac and Windows are also available).

NOTE: A key file is missing from the latest offici
