Projekt Julians Ark Server

Starten

The Island

sudo systemctl start ark1

Maybe later more maps...

Stoppen

Backup gibt es automatisch nur alle 5 min also besser mit SaveWorld:

EnableCheats <Password>
AdminCheat SaveWorld
AdminCheat DoExit

oder statt DoExit

sudo systemctl stop ark1

Lokale Welt auf Server kopieren

lokale SavedLocalArcs nach SavedArks auf dem Server kopieren und lokales Profil einer Steam ID geben

cp -av ~/Backup/Saved.windows/SavedArksLocal ShooterGame/Saved/SavedArks
cp ShooterGame/Saved/SavedArks/LocalPlayer.arkprofile ShooterGame/Saved/SavedArks/76561198229816152.arkprofile

Server im Router freigeben

folgende UDP Ports weiterleiten

4242
7777-7778
26900-26905
27015-27020
27215

Server konfigurieren

sudo vi /etc/sysctl.conf

fs.file-max=100000

sudo sysctl -p /etc/sysctl.conf

sudo vi /etc/security/limits.conf

steam               soft    nofile          1000000
steam               hard    nofile          1000000

sudo vi /etc/pam.d/common-session

session required pam_limits.so

above is probably not necessary if using this service file /etc/systemd/system/ark1.service

[Unit]

[Install]
WantedBy=multi-user.target

after creating/changing the file do a

systemctl daemon-reload

to start the service

systemctl start ark1

to start after every boot

systemctl enable ark1

Updaten

den service restarten führt automatisch ein Update aus

systemctl restart ark1
systemctl status ark1

wenn diese Fehlermeldung kommt:

Error! App '376030' state is 0x206 after update job. :: ARK: Survival...

dann ist wahrscheinlich der Platz in /home/steam ausgegangen.

Konfiguration

im Verzeichnis, das man beim Installieren/Updaten angegeben hat (z.B. ~/servers/ark4walze1) in das Unterverzeichnis ShooterGame/Saved/Config/LinuxServer wechseln. Dort gibt es die Datei GameUserSettings.ini. Diese enthält unter anderem diese wichtigen Einstellungen. Vor allem die letzten beiden muss man bei der Installation anpassen!

ShowMapPlayerLocation=True
proximityChat=True
MaxStructuresInRange=1000
MaxPlayers=10
DifficultyOffset=0.2
SessionName=some-descriptive-name
ServerPassword=some-passsword
ServerAdminPassword=some-other-password

ein paar Einstellungen noch, die das Spiel leichter oder schwerer machen. Bei manchen haben schon winzige Änderungen einen großen Effekt:

NightTimeSpeedScale=3.0
TamingSpeedMultiplier=3.5
HarvestAmountMultiplier=1.5
DifficultyOffset=0.2
XPMultiplier=2

Und noch ein paar Einstellungen in Game.ini

[/script/shootergame.shootergamemode]
MatingIntervalMultiplier=1.0
EggHatchSpeedMultiplier=20.0
BabyMatureSpeedMultiplier=20.0

Neue Map

wenn es eine neue Map gibt, kann man sie als user steam so installieren (statt X eine Nummer):

cp -a ~/servers/ark4walze1 ~/servers/ark4walzeX
cp ~/start-ark4walze1.sh ~/start-ark4walzeX.sh
cp ~/update-ark4walze1.sh ~/update-ark4walzeX.sh

Dann in den Skripten noch das servers Verzeichnis anpassen (1 -> X) und im start-ark4walzeX.sh den Map-Namen (TheIsland?listen -> Ragnarok?listen) oder die Map ID ersetzen

Backup wiederherstellen

wenn's mal nicht so gut läuft, und man deshalb einen älteren Stand wieder herstellen will:

su - steam
killall ShooterGameServer
cd ~/servers/ark4walze3/ShooterGame/Saved/SavedArks
cp -av Ragnarok.ark Ragnarok_bad_luck.ark
cp -av Ragnarok_22.06.2017_18.28.22.ark Ragnarok.ark
~/start-ark4walze3.sh

die Backup Zeiten sind UTC nicht MEZ (also im Sommer um zwei Stunden verschoben, im Winter um eine)

Troubleshooting

First install with steamcmd had to be done with sudo or an error appears after 0% done

After first install, chown install directory and /tmp/dumps from root to steam user then it works fine without root privilege

History

The server did work. Then, after some time (and app/os updates) whithout playing, it no longer works. The server shows up on client list, but on connect attempt it always fails.

Dump all traffic to and from server during a "server start, client connect attempt" event

Dump all traffic during the same event on fritz box

The server was "exposed host" during that time and no firewall was active on the server

Generate capture file for lan in wireshark format: iad-if-eth0_11.03.18_1351.bin
