Hello,
Thank you for this great application. Unfortunately my knockledge in computing is very basic, but i succeeded in setting up a dcm4chee archive. I would like to test and use Orthanc. Installation, access and upload are so simple, thank for that!!!! But i am facing some problems:
1. -I can´t find how to change configuration file (although it is explained, but i have some problems understanding it), could you please give some details how to do it?
2.- During remote access orthanc security area pops up, but i don´t have or can´t set the credentials (see point 1)
Thank you for your help
A S

This is explained on the following page:
[https://code.google.com/p/orthanc/wiki/OrthancConfiguration](https://code.google.com/p/orthanc/wiki/OrthancConfiguration)
In a nutshell, you have to:
1. Generate a sample configuration file: # Orthanc --config=Configuration.json
2. Edit the generated file “Configuration.json” with a text editor (e.g. Notepad if you are under Windows).
3. Launch Orthanc using the modified configuration: # Orthanc Configuration.json
> 2.- During remote access orthanc security area pops up, but i don´t have or can´t set the credentials (see point 1)
In the generated configuration file, you have to set the option “RemoteAccessAllowed” to “true”. For security reasons, remote access is disallowed by default.
Cheers,
Sébastien-

Thank for the quick help. Works perfectly. This seems very promising.

Hello,
Which Linux distribution are you running? Have you compiled the package by yourself? If so, have you used the build instructions for your Linux distribution, as detailed in the following file:
[https://code.google.com/p/orthanc/source/browse/LinuxCompilation.txt#61](https://code.google.com/p/orthanc/source/browse/LinuxCompilation.txt#61)
Looks like the “DCMTK\_DICTIONARY\_DIR” variable has not been set properly when invoking CMake.

Cool thanks;
I am running Wheezy; and used apt-get; I’ll try cmake as noted and report back.

This is strange: There is currently no official backport of Orthanc to Wheezy. Your “apt-get” invocation should thus have failed…
Maybe you have introduced the Debian Jessie/Sid repositories into your apt sources? If this is the case, pay attention to the fact that this approach is doomed to fail.
