In general, a DICOM server is defined by three entities, the:
The Port and AE Title information of the PMOD DICOM server(s) is configured on the DICOM / DICOM SERVER pane.
Note: On Linux systems there exist reserved ports which require special permission to allocate. If such a port is defined as the PMOD DICOM server port, the server cannot be started from a user account and issues a message Permission denied. Starting as root will normally succeed, but this has the disadvantage that the saved files will all belong to the root. To prevent this situation a higher port number (typically >4000) should be used on Linux, rather than the standard DICOM port 104. PMOD uses 4030 per default.
Besides the basic server information there are three checks relevant for the DICOM server operation:
Standard DICOM communication is not secure, and therefore is not recommended over public networks. To overcome this problem, a DICOM supplement was added for implementing secure connections. PMOD supports one of the proposed variants called BASIC TLS SECURE TRANSPORT CONNECTION PROFILE. Of the three optional features (entity authentication, encryption, integrity check) encryption is implemented in the current release. As a consequence, the data transferred can only be interpreted by the target DICOM server with which the communication has been established. To enable secure DICOM, check the Secure (TLS) box. The corresponding command line option is -tls.
