Changing your presence from the Teams Desktop Client

Last week Microsoft released the a small but in my opinion a fundamental feature that i was using many times a day in Skype for Business.

It’s now possible to change your presence status from either the system tray menu or buttons below the Aero thumbnail and changing the presence from the menu (via profile picture) also still exists.

Route all traffic by OpenVPN

In October i posted a blog about setting up your OpenVPN server in 2 minutes.

This blog is a addon to your existing configuration to route all traffic over the VPN. 

Change server configuration

go to the config file (/etc/openvpn/server.conf) and add the following lines:

push "redirect-gateway def1"
push "dhcp-option DNS "
push "dhcp-option DNS 1.1.1.1"

 Restart your OpenVPN daemon

sudo /etc/init.d/openvpn restart

Change client configuration

Change your client config, and add the following line

redirect-gateway def1

Change IP Tables

Last thing to do is change your iptables to NAT traffic to the internet. (make sure you have the right to do this or run this as root)

iptables -I FORWARD -i tun0 -o wlan0 \
         -s 10.8.0.0/24 -m conntrack --ctstate NEW -j ACCEPT
iptables -I FORWARD -m conntrack --ctstate RELATED,ESTABLISHED \
         -j ACCEPT
iptables -t nat -I POSTROUTING -o wlan0 \
          -s 10.8.0.0/24 -j MASQUERADE

Caption:

  • tun0: your virtual VPN network interface
  • eth0: your normal network interface (to make sure you will use the right interface, check with “ifconfig”)
  • 10.8.0.0: your VPN network IP range

Running PowerShell on your RaspberryPi

microsoft loves linux

For many years PowerShell was a Windows-only thing that was part of the closed Windows ecosystem. Now a days PowerShell is open source up at https://github.com/PowerShell with lots of docs and scripts, also open source.

PowerShell is supported on Windows, Mac, and a half-dozen Linux distros.

While running PowerShell on your RaspberryPi is still experimental and only supported for Raspbian Stretch it’s running pretty smoothly.

Skype for Business Online Audio Conferencing – Dial out behavior change

Skype for Business

Microsoft is making some changes to Skype for Business Online Audio Conferencing Dial Out. To best meet our customer’s business needs, Microsoft is adjusting when attendees can add other participants to a Skype for Business meeting via dial out.

How does this affect us?

Till now, meeting guests are able to add Audio Conferencing attendees at any time.

Going forward, the meeting service will require at least one authenticated user from the organizer’s company to be present in the meeting to allow adding another participant via dial-out. Company attendees can be authenticated through the Skype for Business Client.

This new behavior in meeting dial outs will be rolled out in the next coming days.

What do we need to do to prepare for this change?

You don’t need to do anything, but may consider updating your user training, and notifying your helpdesk.
