I have installed the Orthanc server on my Ubuntu 24.04 TLS via the apt install Orthan command. After modifying some parameter in /etc/orthanc/orthanc.json file we can access Orthanc server through the tcp 8042 port with the default username and password.
I searched the Internet and tried chatbots for how we can set up a non-default user account of Orthanc server but they were all not working. These codes did not work.
Thanks for the tip and I will try your method later. But I am pretty sure the configure file is working because it became invalid with uncorrect configurations.
