man echoscu (Commandes) - DICOM verification (C-ECHO) SCU
NAME
echoscu - DICOM verification (C-ECHO) SCU
SYNOPSIS
echoscu [options] peer port
DESCRIPTION
The echoscu application implements a Service Class User (SCU) for the Verification SOP Class. It sends a DICOM C-ECHO message to a Service Class Provider (SCP) and waits for a response. The application can be used to verify basic DICOM connectivity.
PARAMETERS
peer hostname of DICOM peer
port tcp/ip port number of peer
OPTIONS
general options
-h --help print this help text and exit
--version print version information and exit
-v --verbose verbose mode, print processing details
-d --debug debug mode, print debug information
network options
application entity titles:
-aet --aetitle aetitle: string set my calling AE title (default: ECHOSCU)
-aec --call aetitle: string set called AE title of peer (default: ANY-SCP)
association negotiation debugging:
-pts --propose-ts [n]umber: integer (1..28) propose n transfer syntaxes
-ppc --propose-pc [n]umber: integer (1..128) propose n presentation contexts
other network options:
-to --timeout [s]econds: integer (default: unlimited) timeout for connection requests
-ta --acse-timeout [s]econds: integer (default: 30) timeout for ACSE messages
-td --dimse-timeout [s]econds: integer (default: unlimited) timeout for DIMSE messages
-pdu --max-pdu [n]umber of bytes: integer [4096..131072] set max receive pdu to n bytes (default: 16384)
--repeat [n]umber: integer repeat n times
--abort abort association instead of releasing it
transport layer security (TLS) options
transport protocol stack options:
-tls --disable-tls use normal TCP/IP connection (default)
+tls --enable-tls [p]rivate key file, [c]ertificate file: string use authenticated secure TLS connection
+tla --anonymous-tls use secure TLS connection without certificate
private key password options (only with --enable-tls):
+ps --std-passwd prompt user to type password on stdin (default)
+pw --use-passwd [p]assword: string use specified password
-pw --null-passwd use empty string as password
key and certificate file format options:
-pem --pem-keys read keys and certificates as PEM file (default)
-der --der-keys read keys and certificates as DER file
certification authority options: +cf --add-cert-file [c]ertificate filename: string add certificate file to list of certificates
+cd --add-cert-dir [c]ertificate directory: string add certificates in d to list of certificates
ciphersuite options:
+cs --cipher [c]iphersuite name: string add ciphersuite to list of negotiated suites
+dp --dhparam [f]ilename: string read DH parameters for DH/DSS ciphersuites
pseudo random generator options:
+rs --seed [f]ilename: string seed random generator with contents of f
+ws --write-seed write back modified seed (only with --seed)
+wf --write-seed-file [f]ilename: string (only with --seed) write modified seed to file f
peer authentication options:
-rc --require-peer-cert verify peer certificate, fail if absent (default)
-vc --verify-peer-cert verify peer certificate if present
-ic --ignore-peer-cert don't verify peer certificate
NOTES
DICOM Conformance
The echoscu application supports the following SOP Classes as an SCU:
VerificationSOPClass 1.2.840.10008.1.1
Unless the --propose-ts option is used, the echoscu application will only propose the transfer syntax
LittleEndianImplicitTransferSyntax 1.2.840.10008.1.2
COMMAND LINE
All command line tools use the following notation for parameters: square brackets enclose optional values (0-1), three trailing dots indicate that multiple values are allowed (1-n), a combination of both means 0 to n values.
Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behaviour conforms to the standard evaluation rules of common Unix shells.
In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).
ENVIRONMENT
The echoscu utility will attempt to load DICOM data dictionaries specified in the DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable is not set, the file <PREFIX>/lib/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).
The default behaviour should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (':') separates entries. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
