Using DDNS to set up remote access to home server

• Following instructions at https://www.howtogeek.com/66438/how-to-easily-access-your-home-network-from-anywhere-with-ddns/
• I selected DYNU as the Dynamic DNS Service provider and created an account with them: https://www.dynu.com/en-US/. This is a free service and you can get a domain (I chose sanzgiri.freeddns.org) and IPv4 address
• Remote SSH to your machine is as easy as

ssh -A ashutosh@sanzgiri.freeddns.org

• You can remotely suspend your machine using

ssh -t ashutosh@sanzgiri.freeddns.org sudo systemctl suspend

• You can remotely wake up your machine using

wakeonlan -p 4343 <mac-address>

• Note that you need to enable wakeonlan on your motherboard in your BIOS setup. wakeonlan is a perl utility available from

https://github.com/jpoliv/wakeonlan/blob/master/wakeonlan. You can also the “Mocha WOL” app on iOS.
