14 This is not a complete manual. You have to consult the project home
15 page at http://srcpd.sourceforge.net/ for full documentation!
16 srcpd is a UNIX daemon speaking the Simple Railroad Command Protocol
18 (SRCP).
19 Upon start up it reads in the system wide configuration file named
21 srcpd.conf. Contents and structure of this XML-file is explained in
22 detail in the srcpd.conf (5) man page. The SRCP specification is pub‐
23 lished on http://srcpd.sourceforge.net/srcp.
24
27 -h Prints some useful help about command line options and exit
28 -n Do not daemonize upon start-up. The srcpd does not switch into
30 background mode. This option can be used with the Ubuntu upstart
31 system.
32 -v Print program version, SRCP level and exit
34 -f <filename>
36 Use the specified filename as the configuration file. The
37 default value will be defined at compile time and can be dis‐
38 played using the -h parameter.

42 Getting started
43 The srcpd system service (daemon) is compliant to the Filesystem Hier‐
44 archy Standard (FHS, http://www.pathname.com/fhs/). For more informa‐
45 tion and special options about daemon usage please refer to to your
46 system documentation. The following instructions are on a general level
47 of information.
48
51 Please first start assembling a configuration file (srcpd.conf) fitting
52 exactly your needs to connect to your model railway controller inter‐
53 face. Save this file to the directory for host specific system configu‐
54 ration (/etc). The default configuration file delivered with this soft‐
55 ware must be replaced by the new one.
56 As soon as the adapted configuration file is at the right place, the
58 daemon can be started using this command:
59 /etc/init.d/srcpd start
61 If the srcpd is already running, the daemon first must be stopped to
63 get it aware of the new setup. Stopping the daemon is executed in anal‐
64 ogy to the start command:
65 /etc/init.d/srcpd stop
67 Under certain conditions it is also possible to get the daemon re-read
69 its configuration file without stopping it. With respect to hardware
70 access rules under UNIXlike systems, the group and/or user rights must
71 be properly set in srcpd.conf to let the daemon access the appropriate
72 hardware resources at any time.
73 Common model railway interfaces will require access rights for serial
75 lines (RS232, USB), which can be achieved using the proper group rights
76 (e.g. dialout). The ddl-s88 module uses a special system function (iop‐
77 erm) which always needs root rights to perform successfully.
78 To let srcpd re-read its configuration file, assumed the setup men‐
80 tioned before is correct, the following command can be used:
81 /etc/init.d/srcpd reload
83 The log file /var/log/messages or /var/log/syslog of the syslog daemon
85 can be used to monitor occurring errors on daemon start or during cur‐
86 rent operation. With root rights the upcoming messages can be continu‐
87 ously watched in a separate terminal:
88 tail -f /var/log/messages
90 or
92 tail -f /var/log/syslog
94 The verbosity of these messages can be adjusted using the configuration
96 file srcpd.conf. For more information refer to the adequate man page.
