I just built this as VM is my proxmox home lab. Cool project, with some useful functionality.
Saludos desde Peru donde hay alguien muy agradecido con este video, I am very grateful that there are people who take the time and patience to teach the process step by step and correctly verify the process.
You're welcome! :D
Alright 2 years after and im giving this a try. First time user, installed ubunto an hour ago. What an adventure :)
I stumble on the step docker-compose up -d
It tells me docker-compose not found but can be installed with sudo snap sudo apt
Edit:
I got it to work. Started over and copied and pasted the wholes sting.
The video could use revisit :)
I'm glad you got it working! :D and I'll take a look at revisiting it. IIRC I brushed over the docker installation steps since the docker docs are pretty good, but I could've made that clearer :)
@@BitGoblin Thanks man. There were two issues i ran into with this tutorial. And the "sudu iftop" showed no stats of incomming or outgoing traffic. I don't know how to fix this. So i used "docker stats" did which generally showed me if it was working or not. I am also new in terms of dns/ip's etc so i had a bit of reading prior. But as soon as i understood that the LanCache had an ip, and that you had to insert this into the router settings things started rolling. Then changing the network settings on the client was a breeze. Last thing was i couldnt figure out how to save the .env file. You just said "save and exit" and i was stuck on this so long lol.
There is also an issue that i don't fully understand yet. The speeds are really fast to begin with but over time they drop alot. From 800mbs to around 70mbs half way through a "re download" of a game. I dont have a second client pc to this on at the same time to see if the speeds also settle around there. But any data that is not grabbed from the internet a win in my book. :)
Also what is the difference between
Lancache monolithic
and Lancache_dns
Those are the two shown in the docker stats. :)
I used your tutorial as a general method of pointing me in the right direction. Thanks for this!
My guess is possibly something to do with your SSD cache running out of space and it has to wait for writing to the slower part of the drive. Or it could be CPU-related, if it's only in some games that are compressed more.
The lancache_monolithic has everything (I think including DNS?) built into the same image so it's an easier deployment, but makes it hard to scale up if you have lots of clients and need to scale or segment one of the components for whatever reason.
lancache_dns is just the DNS service. If what you have is working I wouldn't sweat it too much lol.
And it's no problem! :D
I think you are right. Thanks mate :)
Error response from daemon: driver failed programming external connectivity on endpoint lancache-monolithic-1 (aae1bbe85c462bbb180d9d1d824deef0871f4abf811354bf741f3b843508d95b): failed to bind port 0.0.0.0:80/tcp: Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use
no idea what to do with this
Can I cache more than games? Like Workshop content or others? I live in a rural area, and my only two ISPs are either a radio provider (which is absolute garbage), or Starlink. Since I am still waiting to get Starlink, I'd love to be able to reduce the load on my internet by caching whatever I can and then serving that whenever it's requested.
In theory it can cache anything that is served over HTTP, though not HTTPS. Lancache is built using a regular old HTTP proxy, so any software that supports routing requests through a proxy or any services you're willing to spoof DNS records for should work.
It should be noted that I haven't tested this personally, so I may be speaking garbage here :)
does this work in a lxc container on proxmox?
Yep! So long as you have network access and ample storage, you should be able to deploy it anyway you choose :)
Thanks for sharing this video, i have a question, After installing that , for a first time user PC download from the real steam service but for the second time another PC or even the same user download still from steam server not my lancache, i don't have any clue 😢
Did you update your DNS settings to use the lancache DNS resolver? If not, then your systems won't know that it exists.
Thanks for your response. Yes I set the DNS address in my router advertised to all users , and clean the users DNS , their connection is stable and I see the Lancache address but they donwload from steam @@BitGoblin
Would it be any better if an ISP used different lan cache servers for every city or state in the USA? Since all ISPs use their own dns server.
Actually that would be a useful thing get the content cached closer to the user (a lot of CDNs), and it would alleviate stress on Steam's servers.
For the user though, it would still be limited to the maximum bandwidth of your internet connection since it'd be outside your LAN, so not super helpful. Unless your ISP/region had an awful upstream connection to Steam, then that could help
I have a lot of erros with upstream timeouts...a few open issues but no solution
Hmm, that's unfortunate. I hope none of the services are blocking it somehow... If it does get resolved I'd be curious to know what the fix was!
@@BitGoblin ive been dealing with this issue over a year now, but nothing is blocking it, tried seperate isps in my home, from cable to dsl, but no success so far, its sad because I host lan at my place for arround 15 people and I like tinkering
Man that's really weird... It's not like an issue with Docker routing or anything? It really sucks to not be able to utilize this and you're like the perfect candidate to benefit from it!
@@BitGoblin as of my knowledge no its a docker routing issue, I could be wrong obviously...but what else could I change in docker routing or similar
great work, i have played with it for a bit an, now i am thinking i have done something wrong, i can only KB down an not MB help please
What are your normal download speeds like? And when you're downloading a game are you seeing any traffic coming from your lancache server?
Can i use synology nas for caching games from steam/ epic ?
I haven't tested it personally, but you should be able to since it all runs in Docker
Hi, do you have any guide to make a DNS server for a ISP provider ? Thx
Tbh I don't have experience managing DNS servers at anywhere near that scale so I probably wouldn't be of much help. The most I've done is using several active directory servers w/ local caches (usually on firewalls) on subnets, for at most like 100 people.
Interesting. I’m wondering what this specific docker package contains.
Do you have to assign a static IP-address for your LANCache VM in the router's LAN settings?
Also, another question, how much does cached data speed up downloads? Would they be around the limitations of the storage used's read/write speeds?
Good questions! If you're doing the monolithic setup then yes you will need to set a static ip, either manually or via static dhcp mapping. This is because your clients need to know what host to point to for DNS lookups, and if the lancache DNS server keeps changing addresses then your PC won't be able to reach it.
If you're doing the modular(?) approach where each service is it's own container, then in theory yeah you could let it be dynamically set. You'd just need a way to update the DNS service with the new IP address automatically.
Depending on your local connections and disk speed anything is possible! Assuming you've got a 10Gb link to your lancache, if you're reading from a HDD you'd be limited somewhere in the ~2Gbps range in the best case scenario, but SSDs can get about 5-6Gbps if it's SATA or saturate a 10Gb link if it's NVMe. So it depends on multiple factors, but usually is pretty easy to upgrade when needed.
yes sure, I use static address and I did not use any limits
I am Anik from Bangladesh. I have a problem! when I download a game with setam client software then I get the download traffic from internet. How I fix this issue? Please help.
I'm sorry, I'm not sure I understand your problem - are you saying that you've set up the lancache server, but your PC is getting the files from Steam directly and not using the cache?
If so, I'd double-check that your PC is using the lancache container's DNS server to resolve hostnames, so it knows where to pull the files from.
How come you use a class A network and not class C network
Honestly, there really is no reason. I just chose a 10.x.x.x for fun :)
@@BitGoblin ah ok I was wondering because the typical ip adress in a home network would be for example 192.168.3.1
@snickgamer4206 yep! It typically is. Now that I think of it, it might have been to avoid potential conflicts with my brother's network if we VPN'd or something, but it's been awhile so I forget lol
how do you save and exit etc/resolv.conf it says that its read only
You need to do so with root privileges, so you can either do "sudo vim /etc/resolv.conf" or escalate to root with "su -" and then try to write the file.
my steam isnt connecting to lancache search
Have you reconfigured your system to use the Lancache's DNS? Else it won't know to use your Lancache server
will this work with windows subsystem for linux?
I believe so, though you may be able to get away with running this natively on Windows with docker
can you set up lancache.... Remotely
I'm not sure what you mean by "remotely"... if you're referring to if you can set it up on like VPS or some other server outside, then yes it can be done but doesn't really help you much since you'd still be limited by your WAN connection.
Can you run this as a VM?
Yep! I ran mine in a VM for the video 🙂
Hey, been a while since I last saw a recommendation from your channel. Weird. good video tho
Thanks! :D
Nice and easy. Thanks 👍
I'm glad you liked it :D
not easy if you're a beginner
