TCP/IP Stack Reset

suggested for Windows 10:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

//batch script alternative//

echo "Starting networking stack reset"
cd %windir%\system32
netsh int ip reset c:\windows\temp\resetlog.txt
netsh winsock reset
netsh int ipv4 reset
netsh int ipv6 reset
echo "Networking stack reset"
shutdown -r -f -t 03

//batch script//

Installing Unifi Controller on Linux

The process is nicely described on Unifi website but for common good I am going to minimize it just to a set of commands you can run on Linux distros like Debian or Ubuntu:

  1. echo 'deb stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list

  2. sudo wget -O /etc/apt/trusted.gpg.d/unifi-repo.gpg or you can also do: sudo apt-key adv --keyserver --recv 06E85760C0A52C50

  3. sudo apt-get update

WinSCP and Putty Sessions Backup

WinSCP and Puttyt are small but convenient IT tools. Unfortunately they lack backup tools, so moving yourconfiguration to a different machine or restoring after reinstallation seems like a problem. But it is really not a problem if you are familiar with Windows registry.
