What data is Hamachi sending?

[pietpetoors]

I use Hamachi to connect our different branch computers via remote desktop.

I see that if I right click a computer on the network and select "details", in the window it opens, it shows how much data was sent to that computer from the server. It is 20h45 at night, I am the only one working, but yet Hamachi is sending and receiving to and from all computers. It is about 20Mb per hour per computer. Not much, but with ten computers that is 200 Mb per hour going down the drain while nobody is working.

Anybody perhaps know what it is sending or how I can check what it is sending?

Sending far more than receiving, Out is 19,457 Kb and in is only 540 kb

Isnt there a better option than hamachi

200 Mb per hour going down the drain while nobody is working.

This is surely just data across a local network? If so does it really matter if it's 200mb or 2gb or 2mb?

Sounds like a terrible plan.

The built in windows resource monitor should be able to tell you whats using the data

No between branches like between Cape Town and JHB is not on a LAN, it is via ADSL

In the mean time we figured out it seems to be remote desktop which is sending the data. If remote desktop is open on the server and hamachi is connected and I am not using remote desktop, it is still sending data. We thought is was Hamachi because each time you connect hamachi it is sending data. Then I saw when I close the RD connection completely but keep Hamachi connected it stops. So whether you use remote desktop or not, if the RD connection is open it sends data.

Solution now is to just close remote desktop and hamachi when not using it.

Maybe someones accessing it remotely

When I last used hamachi (2010-ish)
It creates a virtual layer 2 network ("LAN"), the traffic you are seeing is standard windows "management" traffic.
General things like Netbios, ARPs and SMB control traffic is the culprit there (Windows keeping track of other computers on the network so you can see them by name in network places), 20Mb per hour per PC sounds completely normal for idle traffic.
Hamachi is designed to create a virtual LAN over the internet for games.
By design, LAN networks are full of "junk" traffic like broadcasts and multicasts, because bandwidth isn't an issue on a LAN, so it wasn't designed to be low-usage.

If wasting bandwidth is a concern I'd suggest something like a Layer 3 VPN + traffic compression.
SoftEther VPN is a good start for you to look at, and is by far the easiest VPN software to setup and impliment.

Erm, set up a VPN please, don't use Hamachi for business stuff. Encrypt your junk, make sure you own the key.

Softether is an open source VPN server and client manager.

L2TP/IPSec is your friend
