Hello (word used as a greeting or to begin a conversation)

What kind of files are you trying to send ?

You should enable the trace logs to analyze the DICOM association in details.

Best regards,


Hi Alain

I am sending DICOM study. Little more context - I was able to establish the connection from orthanc to another orthanc ( in other server) with the dicom modalities entry as above.
The orthanc log setting link that you posted for verbose, I tried setting the verbose option( non-docker options in Linux) but not able to get this activated.
For example, when i run this: sudo -u orthanc /usr/sbin/Orthanc --verbose /etc/orthanc/ > Orthanc.log 2>&1 it gives a permission error.
Then I tried sudo /etc/init.d/orthanc start --trace --logfile=orthanc.log but can’t see any details other than posted in the UI.

I am quite new to this. So, I can send apologies in every sentence for what I am trying but I am assuming you/community will understand the beginner level user. Thanks for sending the note. Let me know if there is more that I need to provide to get the help.

Thanks & Regards
