Mikrotik UDP port 5678 usage is for MikroTik Neighbor Discovery Protocol (MNDP)

Posted by jpluimers on 2017/08/14

Just in case you see UDP port 5678 in the firewall log of your MikroTik device: it’s usage of the MikroTik Neighbor Discovery Protocol (MNDP) [WayBack] protocol.

You can either block Neighbour Discovery [WayBack] in the firewall or turn it off on the MikroTik Services [WayBack] or inspect any of these protocols:

Play to Chromecast from VLC 3.0 on Mac OS X (OS X, macOS, or whatever other names apple comes up with)

Posted by jpluimers on 2017/08/14

On my Mac OS X machine, I got this to work with the 20170731 nightly of VLC 3.0.

[WayBack] How to stream from VLC to Your Chromecast (3.0 Updated Version) – VLC Media Player only explains the steps for Windows and Android, probably because they were the first platforms supported by VLC to render on Chromecast: [WayBack] How to Stream Videos from VLC to Chromecast (Including on Windows, Mac & Android) / [WayBack] How to Stream From VLC to Your Chromecast

To make it easier for end-users, on other platforms the menu entries are different.

  • Windows: Menu Video -> Render
  • Mac: Menu Playback -> Renderer (not Render as shown in some posts)
  • Linux: No UI yet.

I found this via [WayBack] Latest VLC 3 Nightly Streams to Chromecast Perfectly! : Chromecast and [WayBack] How do I stream to Chromecast using VLC? – Unix & Linux Stack Exchange

On Linux, there is the command-line for now (which works on OS X and Windows as well), or if you insist: use MKChromecast as described in [WayBack] How To Cast Video from Ubuntu to a Chromecast – OMG! Ubuntu!. [WayBack]Mkchromecast This is a program to cast your macOS X, or Linux audio to your Google Cast or Sonos devices with sources at https://github.com/muammar/mkchromecast

On Windows and Mac OS X, after choosing the Render, the steps are the same:

  1. Choose Render discovery on
  2. Choose a Chromecast device
  3. Accept the security certificate for it

Download: [WayBack] https://nightlies.videolan.org/build/macosx-intel/vlc-3.0.0-20170731-0451/vlc-3.0.0-20170731-0451-git.dmg via [WayBack] https://nightlies.videolan.org/build/macosx-intel/vlc-3.0.0-20170731-0451/

I didn’t need [WayBack] https://nightlies.videolan.org/build/macosx-intel/vlc-3.0.0-20170731-0451/vlc-contrib-x86_64-apple-darwin15-20170731.tar.bz2
