Lancache Issues

[TinsellyCone241]

I have been using a software called LanCache to setup a steam cache, and I cannot connect to my server. I have set the DNS on my PC to the server's IP address which is static, but when I run NSlookup I get this:

Spoiler

(Me)>nslookup cache.steamcache.lancache.net

Server:  UnKnown
Address:  10.0.0.254

*** UnKnown can't find cache.steamcache.lancache.net: No response from server

It does find the correct IP address, but it won't work.

Well your computer is still trying to use 10.0.0.254 for DNS, isn’t the server’s IP 10.0.0.253 now?

No, 253 would be dynamic because its in the DHCP range. The server's IP was 255 but then we put it to 254 so it would work.

Sorry I went back to the other thread and reread. I forgot. 
So we made sure the server is on the right IP. At this point I can think of two things:

-firewall on the server is blocking all inbound connections - need to allow in UDP/53

-docker network config is incorrect, need to make sure that port 53 on the host is being passed to port 53 of the container. This is basically the same as port forwarding on a router.

I don’t have enough experience to give you exact instructions on either of these.

 

Edit: also, make sure you can ping the server from the computer. Note that linux default firewall allows incoming pings, windows default firewall does not. So if you make no firewall changes, you can ping from a windows computer to a linux one but not vice-versa.

No problem. I don't really use Linux much, but I think the firewall is off.

I have played around a bit and done some research but I can't really find much on how to pass through ports to docker. If you could find like a video or article on how to do this, I will do my best to follow it. I will keep looking.

I’m pretty sure its in the command when you create the container. For example:

Quote

docker run --name lancache-dns -p 10.0.0.2:53:53/udp -e USE_GENERIC_CACHE=true -e LANCACHE_IP=10.0.0.3 lancachenet/lancache-dns:latest

Would pass 10.0.0.2 (replace with the host’s actual IP) port 53 to port 53 of the container.

I did not use a command such as this. I just installed docker via Git, edited the config files with a nano command, and used "docker-compose up -d" to start lancache. Then it ran a ton of scripts and stuff. I just did what was in this video.

Hi guys so I really wanted to get a NAS but the only problem is I am not able to justify its cost bcos the only use I have is that I am going to use it as a steam cache, is there any other use u guys can think of ?

You may not have used a command like that, but it would have been in the scripts that were run. It *should* have included the assignment of udp/53 to the container, but when things aren’t working, I trust nothing.

If your budget is that strict, how many computers do you have the same game installed on? a Steam cache may be pointless for you....
