CUPS Remote-Zugriff Webinterface

• Standardmäßig lässt sich das CUPS-Webinterface nur vom localhost auf Port 631 bedienen
• ss -lntp | grep 631

• systemctl restart cups
• ss -lntp | grep 631

LISTEN 0      128          0.0.0.0:631       0.0.0.0:*    users:(("cupsd",pid=4247,fd=6))                                                   

• Nun sollte das Webinterface vom Host mit der IP 192.168.56.254 erreichbar sein
