Steam file transfer over local network? (lemmy.ml)

Anyone got this to work between a linux host and a steamdeck?

I am using the arch package of steam on the host, I opened the necessary ports, but I can't get the two to download from each other (just to be safe I completely disabled the firewall on both devices and tested, doesn't work).

Steam's remote connection logs mention receiveing broadcast from the other device and when I start the download, the server briefly starts saying "hosting local file transfer" in its downloads page but stays in 0% a little while and disappears.

It just worked for me between two archlinux systems. Desktop and laptop. But somehow it was super slow, turning that feature off and force downloading from the internet was way faster.

Can you maybe try connecting them directly to each other without a router and without internet? Afaik KDE has a hotspot button/setting somewhere.

I am thinking either your router blocks it (some routers have this as a security feature, that a lan cabled devices can't talk to a wifi connected devices) or the algorithm is smart and local transfer is slow so it switched to downloading from the web.

There are a couple of variables why it would be slow for you. Steam sharing works great as long as:

Host isn't downloading something
Client isn't downloading something
Client has a fast CPU to still unpack the game
Client has fast storage to saturate the network speed
Host has good network speed
Client has good network speed

For me, it really is that simple. It sometimes even works better than the server cache setup

Note though, you really need a FAST CPU to unpack steam games at even gigabit. It will also make bad SSDs cry.

Can you do it again and share that graph? is the green line higher than the blue bars?

In my case I think it's just the congested WIFI in my area.

And I have no way to cable up the devices without having cables going through my whole apartment.

The client here is a steamdeck and its hardware supports receiving. Either way, even if its cpu is bottlenecking, it'll be faster than downloading from the internet.
