Use VNC on Tunnel Linux

-

Please follow below documents to take VNC Session. You need to run highlighted command with Yellow on servers.

  • Need a vnc-server installed;  it’s tigervnc-server for RHEL7
  • Team will start VNC server process(es) as desired
    • May be one “shared” session for particular/common account to be used across timezones/globe
    • May be one per actual user (A vs. B)
    • Vncserver starts using ports at 5901, but user could specify any port number, even one in their 10,000 list of port exceptions for EIP
  • Team must launch vncserver with the -localhost directive
    • This prevents from binding to any network interface other than localhost
    • Forces them to use an SSH tunnel to access the VNC server
  • No firewall rules for any of the vnc ports, aka 5901…must be over SSH tunnel
  • Any other VNC configuration is on the DBAs; is not a root managed daemon that is started on boot

vncserver -autokill -IdleTimeout 900 -localhost

    • VNC SSH Tunnel on local computer (5901 is only an example. It may be 5902 or higher, depending on different factors.)
ssh -L 5901:localhost:5901 -N -f -l $DOMAIN\\$USER $SERVER

IPFS powers the Distributed Web A peer-to-peer hypermedia protocol designed to preserve and grow humanity's knowledge by making the web upgradeable, resilient, and more open. The web of tomorrow needs IPFS today IPFS aims to surpass HTTP in order to build a better web for all of us. Today's web is inefficient and expensive HTTP downloads files from one server at a time — but peer-to-peer IPFS retrieves pieces from multiple nodes at once, enabling substantial bandwidth savings. With  up to 60% savings for video,  IPFS makes it possible to efficiently distribute high volumes of data without duplication. Today's web can't preserve humanity's history The average lifespan of a web page is 100 days  before it's gone forever. The medium of our era shouldn't be this fragile. IPFS makes it simple to set up resilient networks for mirroring data, and thanks to content addressing, files stored using IPFS are automatically versioned. Today's web is centralized, limit...
