echoscp¶
echoscp [options] port
Description¶
The echoscp
application implements a Service Class Provider (SCP) for the
Verification SOP Class (UID 1.2.840.10008.1.1) 1. It establishes an
Association with peer Application Entities (AEs) and listens for
DICOM C-ECHO-RQ 2 messages to which it responds with a DICOM C-ECHO-RSP
message. The application can be used to verify basic DICOM connectivity.
The following example shows what happens when it is started and receives a C-ECHO request from a peer:
user@host: echoscp 11112
More information is available when a connection is received while running with
the -v
option:
user@host: echoscp 11112 -v
I: Association Received
I: Association Accepted
I: Received Echo Request (MsgID 1)
I: Association Released
When a peer AE attempts to send non C-ECHO message:
user@host: echoscu 192.168.2.1 11112 -v
I: Association Received
I: Association Accepted
I: Aborting Association
Much more information is available when a connection is received while
running with the -d
option:
user@host: echoscp 11112 -d
D: $echosco.py v0.4.1
D:
I: Association Received
D: Request Parameters:
