Native Linux server (with management scripts)

[seanzy13]

Is there any way to force a 2nd install of the entire game engine using this management script so I can run servers with unique mods? Can I somehow install a 2nd copy of the script with a new name and use it to install a 2nd copy? What would be the best way to go about this?

Not directly supported. You'd have to either create a second set of the scripts that point to a different script-config (as well as updating all the links between the individual script files) which would probably be the clean way; or just create a second engine folder and copy the start-script to have one start command for the original folder and one for the new folder. In that case you'd have to be careful with starting the different saves with the appropriate command though as otherwise it might break saves if they don't run with the same mods each time.

Thanks! I ended up going the route of changing all the scripts and pointing them to new paths for a completely separate installation. Wasn't too difficult, just gotta make sure you get all of them. I was thinking it would be cool to have a script to modify the script like this, but then I figured it would be easier to just build the functionality into the existing script to either create a new instance of an existing engine, or install a fresh engine. Just an idea. If I could do it I would, but I'm all new to this as of about 2 weeks ago. I will attempt to learn more, but if you or anyone else with more experience then me would add this that would be awesome. Thanks for the awesome scripts to begin with, they make linux servers so much less of a headache!

Problems trying to use automated scripts

 

I was trying to set up a dedicated server following your wiki, it shows to do

wget http://svn.illy.bz/7dtd/bootstrapper/bootstrap.sh

 

but when i do, i get an error message 401 Authorization Required, am I doing something wrong?

I then tried to do the manual way with

wget http://illy.bz/fi/7dtd/management_scripts.tar.gz

but that returns 404 not found....

 

What am i doing wrong?

[Alloc]

What am i doing wrong?

Good question ... just tried and both download just fine

Some proxy in between that might block that stuff?

FWIW I just tried this and was able to pull the file down without any trouble. Does svn.illy.bz resolve to 178.63.97.203 for you? I'd also try pulling it up on a browser to see what response you get.

Yeah, and no blocks on my end (at least not on HTTP level, got a few chinese IPs/ranges blocked on the FW, but that wouldn't result in any HTTP error codes).

Still got the Problem

 

Hello Guys,

 

i followed the Tutorial on Page 46 for my Linux Server.

 

But i got still this Problem :

 

root@vps:~# 7dtd.sh start MyStarvationMod

i installed already libc6-dev..

 

Can anyone help me pls?

 

Thank you!

Well, you failed to compile the daemon during installation of the scripts. Go to /usr/local/lib/7dtd/start-stop-daemon and run make. Either it succeeds in which case you're done or it fails and in that case you'll have to fix the reasons why it's failing (most likely missing dependencies for compilation).

Hello everybody.

 

I have a problem with the management scripts.

 

My environment:

V server: Ubuntu 16.04.2 LTS (GNU / Linux 4.4.0-042stab123.1 x86_64)

 

 

When I try to create an instance or try to edit an instance or do anything with the scripts, the following error appears (e.g print the config of instance "test"):

Sounds like the contents of /etc/7dtd.conf were corrupted. Would recommend starting with looking at that file first, should be similar to https://7dtd.illy.bz/browser/scripts/etc/7dtd.conf

OK, problem solved. The .conf would be encryped during the installation - however this could happen.

Big thanks to you Alloc!

Allow normal user start instance?

 

Hello again, another question:

 

How can I allow my fellow players to start and stop the instance without giving them access to the entire server via root or sudo?

Is there a way to allow the user (or the group) "sdtd" only to start the start script so that the instance then runs?

 

Or is there another way to do so?

I would recommend looking at the EXAMPLES section of the sudoers man page. You're looking for something along the lines of...

username ALL=/usr/local/bin/7dtd.sh

 

Or if you want to be more granular...

 

username ALL=/usr/local/bin/7dtd.sh start,/usr/local/bin/7dtd.sh kill

Sometimes the server connection fails at start

 

There is still a small problem. Perhaps someone knows the solution:

 

It sometimes happens that I can not connect to the server (with the running network game).

 

The game only returns the error message: "Error: could not connect to server: could not retrieve server information". The log website is not running either.

 

The server has been started and is also running (shows the status).

 

The only thing that helped so far was when I edit the instance (save without changing something is usually enough). Only then I can connect again with the network play and the log web page works again.

 

When i kill the instance this text is coming up:

 

Trying to gracefully shutdown...
/usr/local/lib/7dtd/common.sh: line 210: nc: command not found
Waiting for server to shut down...
1/5
2/5
3/5
4/5
5/5
Failed, force closing server...
Done

 

Unfortunately, I can not say whether this is related, or just coincidence.

Any working fix for error "Too many open files"?

 

All limits already increased to maximum.

 

Can't use web map. It always cause error on maprender and server become unaccessible.

[LHammonds]

Howdy,

 

Just thought I'd drop by and share another script I created for my server which is based on Alloc's fixes.

 

Source: http://hammondslegacy.com/forum/viewtopic.php?f=40&t=213&p=508#p508

 

Here is a horde notification script for players which I tested on Ubuntu Server 16.04 LTS but should work for most other flavors of Linux since it uses Bash.

 

Create a file such as sdtd-horde-notify.sh and set permissions on it:

 

mkdir -p /var/scripts/prod
touch /var/scripts/prod/sdtd-horde-notify.sh
chown root:root /var/scripts/prod/sdtd-horde-notify.sh
chmod 755 /var/scripts/prod/sdtd-horde-notify.sh

 

Add the following text to the script:

#!/bin/bash

## Purpose       : Notify players once a day about approaching horde night.
##     1. Only process this script if there are players online.
##     2. Only process this script if the time is > 5:00 am in-game.
##     3. Finally, send chat message with how many days until horde night.

You can then schedule it in the root account (accessible by doing "sudo su" from your admin account) and then type "crontab -e"

Summary of what it is doing:

 

The schedule is configured to run the script every 5 minutes for instances of servers called "HamCraft", "WalkingDead" and "Vanilla"

 

Even though it runs often, it will only generate an in-game message once per day shortly after the desired hour...which is set to 5am in the script via the "Hour2Notify" variable.

 

Here are all the possible messages players will see in the game:

 

[iNFO] 6 days until horde night.

[iNFO] 5 days until horde night.

[iNFO] 4 days until horde night.

[iNFO] 3 days until horde night.

[iNFO] 2 days until horde night.

[iNFO] 1 day until horde night.

[iNFO] Horde night tonight!

I had this same error forever ago, Sylen or Alloc helped me fix it. I'll have to go back through my posts to find it, but I started using the dynamic map and not rendering the map and it eliminates that issue. I'm at work, give me time and I'll find the post.

Can't use web map. It always cause error on maprender and server become unaccessible.

Is it still really giving you that error or are you just having issues with the web map?

I'd bet it's safe to say that if you're really hitting the open files limit you either haven't increased the limit enough or you did something wrong with that.

 

 

 

I just setup a new Ubuntu 16.04 server and I noticed this message below when I was running bootstrap.sh. I've installed all the prerequisites. Did I do something wrong? Does this message mean anything?

 

insserv: pushd() can not change to directory /etc/init.d: No such file or directory
update-rc.d: error: insserv rejected the script header

Looks like the installation failed as there was an issue with /etc/init.d not existing. I suppose that's due to the switch to systemd. In the end it shouldn't matter a lot though, it just means it won't auto start any instances during system boot.

 

I also notice that if I try to use the bash auto completion I don't get the results that I get on another server that I setup that's running the scripts.

Most likely bash-completion is not installed or activated for root.

[sphereii]

For the bash-completion, you probably have a symlink from /bin/sh to /bin/dash, rather than /bin/bash

 

You can change it back to bash by doing this as root:

 

rm -f /bin/sh

ln -s /bin/bash /bin/sh

Just some a16 Experimental Updates....

 

The script does not create the following items in the config file.

  <property name="BedrollDeadZoneSize"  value="15"/>     
 <property name="BloodMoonEnemyCount"  value="8" />     
 <property name="HideCommandExecutionLog"    value="0"/>   
 <property name="MaxUncoveredMapChunksPerPlayer"  value="131072"/>     
 <property name="ServerAdminSlots"   value="0"/>    
 <property name="ServerAdminSlotsPermission" value="0"/>      
 <property name="ServerDisabledNetworkProtocols" value="UNET"/>      
 <property name="ServerReservedSlots"  value="0"/>     
 <property name="ServerReservedSlotsPermission" value="100"/>      

 

The following line is removed.

  <property name="EnemySenseMemory" value="60"/>

 

Also, just a general note on changes...

 

Default server port has been 26900 for ages, but script still uses 25000.

LandClaim Size default is now 41. I think the script uses either 30 or 7. I can never remember.

 

 

 

Almost forgot, EnemySenseMemory will prevent your server from starting.

OOh, found another one. EnemySpawnMode is not 0-5 or whatever it was. It's True or False. Again, incorrect input will prevent it from starting.
