7DtD Linux Server: Running, but can't connect.

[LordSith77]

I have searched, Googled, and everything I could to try and figure this out.

Ubuntu 20.04, running on a HPE ProLiant DL380 G7 Server.:
CPU
Model: Intel(R) Xeon(R) CPU X5660 @ 2.80GHz
Cores: 24

Memory
Mem: total used free cached available
Physical: 44GB 6.9GB 36GB 7.1GB 36GB
Swap: 2.0GB 72MB 2.0GB

Storage
Filesystem: /dev/sda5
Total: 941G
Used: 127G
Available: 766G

All needed ports are opened in UFW and forwarded in router.:
Game 26900 udp 1
Game+2 26902 udp 2
Query 26900 tcp 1
Web Admin 5000 tcp 1
Telnet 8081 tcp 0

Server starts, and I can log in to the Web Control Panel. ./sdtdserver details shows it both started and listed.

But it doesn't show up anywhere. Not in Steam servers list, not on the LAN tab, and if I try to connect manually with external or internal IP, it times out.

When I first set it up using regular SteamCMD it worked for 1 day, then gone. I have tried everything under the sun to get this working. So I'm hoping someone here can point me in the right direction. GSM seems to make things easier, but still at a loss as to why it's not showing up anywhere and I can't connect to it.

Thanks for any and all help.

Did you find any solution to this? I'm having the same or similar issue on ubuntu. I can start the game using GSM or just from the command line, and it appears to run; no crashes. But netstat -tulpn doesn't show the configured ports as listening.

[LordSith77]

Sadly no. I've given up. I've tried every game server for Linux I could find and I couldn't get a single one working.

Thanks, and sorry to hear you're still having trouble. I managed to resolve my issue which appears to be a different problem. But in case it helps future visitors, here are some more details about my problem:

• fresh install of Ubuntu 21 in an unprivileged LXC (proxmox host)
• fresh install of LinuxGSM sdtdserver
• update game to 'latest_beta' (alpha 20 at the time)
• migrate an old game save + generated world (I now know that this was incorrectly exported and thus incorrectly imported)
• when i would start the new server, it appeared to start fine (no catastrophic crashing or error messages in console output). But, having never adminstered a 7dtd server before, I failed to realize that the game simply wasn't starting correctly / fully.
• netstat -tulpn and ./sdtdserver monitor showed that the game's process never registered to listen on any ports.
• start a default game config with no pre-existing save and everything works. Checking the console log revealed that there should be more happening. It's unfortunate that the game's/GSM's console output doesn't really show anything helpful when the game can't complete starting because of an invalid game save.

problem with my game save:
In alpha 20, the game state files are in a 'Saves' directory, and when using generated worlds, a 'GenerationData' directory (which corresponds to the UserDataFolder property in the server config). My previous export didn't have the 'GenerationData' and would just keep the game process in a limbo state. Bringing the 'GenerationData' directory over to this server fixed everything. Game starts and listens on the specified ports, and the game state and world is brought back to the save.

I wouldn't use Ubuntu 21 yet.
Use a LTS version.

Hello there

Sorry for my late answer, there are Couple things to do to get your Server running.

First of all, is it installing properly no dependencies issues ?
Have you forwarded all port you need?

Then here is a tricky part, the normal settings kicking you out from connecting, seach for this line
<property name="ServerDisabledNetworkProtocols" value="SteamNetworking"/>
delete the SteamNetworking and leave the option black like this
<property name="ServerDisabledNetworkProtocols" value=""/>

Some more issues i run in in the couple last weeks:

1. After reinstalling the server, delete ur downloaded world, if its running on same name, and ofcourse ur world you played before.
2. If you playing with mods, leave a comment with stand still 1 Min after logging out, this causes some Corruption on Player data with the Player. If you run straight into logout. <-- Happens twice with mods, after standing still its gone.

Hope this helps.

I know this is late, but...

It doesn't seem like the ports you have opened are correct.
Here is a link to what you need to have open for ports.

You should have 8gb of swap also.

I just used my local IP and password as the input for the server in-game and it connected from another computer, so I know my server is working. Only issue is how do I test if external connection is possible. Is there a way to test this from my internal network, or do I have to ask a friend to try to connect. (I made the server unlisted, but if I make it friend invite only would my friend be able to connect to my server, while I'm connected locally and invite him (with the current computer settings)? That would be the next thing I should test.

[MWRtv]

One thing I changed what the SteamNetworking option in the serverconfig.xml to just be blank "". I don't know if that would have affected me joining locally or not. (Just thought I'd mention it.)

[LordSith77]

As for your serverIP, you need to input your external IP or people outside of your home network won't be able to join.
As for the IPTables, that depends on your Linux version and if it's using IPTables.
As for the swap, you can change it again, depending on what flavor your running. I'm using Ubuntu 20.04, and followed this guide to increase mine:

To clarify about the external IP, this is the one that shows up on the server list in-game for the IP address section when the server is highlighted(when it is not unlisted)? And would it be the same IP that would appear if I did a IP address lookup online?

I did a quick search and my OS does use iptables (in general), but I'm not sure if it needs or turned on or activated, or if it only needs rules to be added. It also has the ufw command (which I used to allow the ports for the server), so I'm confused whether I have to use both.

I'm running Parrot OS, it's build on Debian, which is what Ubuntu is based off of iirc. Why I have Parrot OS? A friend recommended me to use it, so I tried it (and haven't switched back to a normal flavour). However it's a little bit in need of an upgrade, and it has a weird command to update/upgrade it (should be apt-get update && apt-get upgrade, but it's not for this flavour of linux. I've tried it using the Debian commands but it broke the system last time I tried). I'm thinking of just doing a barebones install of Debian and setting up the sudo user and other user accounts needed for the SteamCMD/server files. But, before that I will try the link you posted.

Thanks for the quick reply, btw.

@LordSith77 Were you able to get your server for 7dtd up and running?

[LordSith77]

I did eventually get it going. My problem was that my server wasn't using UFW at all (I use VirtualMin on this server), and hadn't opened the ports in the firewall (since I was thinking it was UFW and running commands for those). I have since changed even that over to CSF, which from my understanding is just so much better. I had everything up and running with normal install though, not using GSM.
Of course now that A21 is out, I'm running into all sorts of new issues. But That's 7DtD for you. LOL

[KeepSmileHope]

Thanx for your answer, the fault was in the settings data under disable networking. For what ever reason it seems that 7dtd had blocked steam networking by itself. How ever if you clean out the "steam networking" the connection was fine. BadPlayer ***@***.***> schrieb am Mi., 30. März 2022, 22:47:
