Branding your Office365 Login Screen

12/12/2018 1 Comment

Using your organization’s logo and custom color schemes to provide a consistent look-and-feel on your Azure Active Directory (Azure AD) sign-in pages. Your sign-in pages appear when users type in their sign in to your organization’s web-based apps, such as Office 365, which uses Azure AD as your identity provider.

Some people maybe notice where this background is from, for the ones that don’t know this is from Mr Robot.

Customize your branding

Sign in to the Azure portal using a Global administrator account for the directory.

Select Azure Active Directory, and then select Company branding, and then select Configure.

On the Configure company branding page, provide any or all of the following information.

Microsoft Teams

Changing your presence from the Teams Desktop Client

11/12/2018 No Comments

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

11/12/2018 No Comments

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 <internalDNSIP>"
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

06/12/2018 No Comments

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.
