Verwalten von Virtualbox-VMs mit Remotebox auf Debian-Stretch: Verbindungsfehler nach dem Neustart

ich habe virtualbox auf einem debian strech-system und dem extension-pack ohne probleme installiert. Ich habe auch remotebox (RemoteBox-2.4) auf einem separaten Client installiert, um auf die virtuellen Maschinen zuzugreifen.

Schritte, die ich tat, um Virtualbox zu installieren und zu konfigurieren

#add repository to debian /etc/apt/sources.list deb https://download.virtualbox.org/virtualbox/debian stretch contrib to  /etc/apt/sources.list  download and add keys wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add - wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -  sudo apt-get update sudo apt-get install virtualbox-5.2  #Download Virtualbox Extension Pack wget https://download.virtualbox.org/virtualbox/5.2.8/Oracle_VM_VirtualBox_Extension_Pack-5.2.8.vbox-extpack  #Install Virtualbox Extension Pack /usr/bin/vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-5.2.8.vbox-extpack   adduser virtual usermod -aG sudo virtual # optional add user sudo-list visudo  usermod -aG vboxusers virtual groups virtual nano /etc/default/virtualbox # add the following content VBOXWEB_USER="virtual"  VBOXWEB_TIMEOUT=0  VBOXWEB_LOGFILE="/var/log/vboxwebservice.log" VBOXWEB_HOST="172.12.1.11"   touch /var/log/vboxwebservice.log chown virtual:vboxusers /var/log/vboxwebservice.log  #check, if the vboxweb-service is allready running systemctl status vboxweb-service  # if the vboxweb-service is allready running, stop it systemctl stop vboxweb-service  # remove the autostart entry if exists systemctl disable vboxweb-service  # change /etc/default/virtualbox if needed  # enable vboxweb-service on startup systemctl enable vboxweb-service  # start vboxweb-service.service systemctl start vboxweb-service  # check the status of the vboxweb-service systemctl status vboxweb-service vboxweb-service.service Loaded: loaded (/usr/lib/virtualbox/vboxweb-service.sh; enabled; vendor prese Active: active (running) since Tue 2018-03-27 11:49:02 CEST; 15min ago Process: 4891 ExecStart=/usr/lib/virtualbox/vboxweb-service.sh start (code=exi Tasks: 18 (limit: 9830) CGroup: /system.slice/vboxweb-service.service ├─4903 /usr/lib/virtualbox/vboxwebsrv --background -H 172.12.1.11 -t  ├─4905 /usr/lib/virtualbox/VBoxXPCOMIPCD └─4910 /usr/lib/virtualbox/VBoxSVC --auto-shutdown    # check which process is used from vboxweb-service ps -aef | grep vboxwebsrv  # check, if the port 18083 is up netstat -an |grep 18083  # connect with the remotebox-client --> Works. 

Nach erfolgreicher Verbindung neu starten. Nach dem Neustart kann ich keine Verbindung zu Port 18083 herstellen

systemctl status vboxweb-service ● vboxweb-service.service Loaded: loaded (/usr/lib/virtualbox/vboxweb-service.sh; enabled; vendor prese Active: active (running) since Tue 2018-03-27 13:38:34 CEST; 3min 4s ago Process: 1041 ExecStart=/usr/lib/virtualbox/vboxweb-service.sh start (code=exi Tasks: 16 (limit: 9830) CGroup: /system.slice/vboxweb-service.service ├─1059 /usr/lib/virtualbox/vboxwebsrv --background -H 172.12.1.11 -t  ├─1061 /usr/lib/virtualbox/VBoxXPCOMIPCD └─1068 /usr/lib/virtualbox/VBoxSVC --auto-shutdown   ps -aef | grep vboxwebsrv virtual 1059 1 0 13:38 ? 00:00:00 /usr/lib/virtualbox/vboxwebsrv --background -H 172.12.1.11 -t 0 -F /var/log/vboxwebservice.log root 2208 1903 0 13:42 pts/0 00:00:00 grep vboxwebsrv  netstat -an |grep 18083 --> no results.  

Wie löse ich das Problem manuell:

(as root) systemctl stop vboxweb-service systemctl start vboxweb-service  --> 18083 port available 

Ich kann mich verbinden und alles ist gut.

Ich habe diese Anweisungen verwendet, um den vboxweb-Dienst einzurichten: http://remotebox.knobgoblin.org.uk/docs/remotebox.pdf

Ich habe keine Ahnung, was falsch ist. Jede Hilfe wäre dankbar.

Vielen Dank
