I’ve learned that the fastest way to transfer files is via Ethernet. Now the easiest way to transfer via Ethernet is for both computers to be on the same local area network. However, if needed, an Ethernet cable can used between two computers.
In order for both the computers to recognize each other, they need to be on the same subnet.
First on both computers, find out which network device is your Ethernet.
ip addr show
Then on both computers assign an unique static ip address,
sudo ip addr add 10.1.1.2/24 dev en0
In this example,
10.1.1is the subnet that the computer is assigned to.
2will denote the unique ip address
/24defines the first three digits as the subnet
en0is the example network device that’s the Ethernet.
Once that’s in place you should be able to
rsync between the two computers!
If you run into issues, it might be a firewall problem…
To remove the static ip assignment, replace
sudo ip addr del 10.1.1.2/24 dev en0
