6 HELIOS directory structure
The following directory listing shows all files created in the "HELIOSDIR" file system after installation (Fig. 35):
The "HELIOSDIR" directory contains besides its six subdirectories ("bin", "etc", "lib", "public", "sbin", and "var") a number of "Manifest.<product>" files which list the installed files for each installed HELIOS product. The two files "Manifest.base" and "Manifest.data" are obligatory and exist always after the HELIOS base installation. Other "Manifest.<product>" files are created with each HELIOS product that is installed, e.g. "Manifest.es" appears after the installation of EtherShare, "Manifest.pcshare" after a PCShare installation, etc.
In the following, we shortly describe the content of the subdirectories in "HELIOSDIR" and provide more detailed information on the files in "bin", "sbin", "var/conf" and "var/spool".
6.1 HELIOSDIR/bin
The "HELIOSDIR/bin" directory contains all available applications and tools, e.g. user utility programs:
"authutil", "dt", "htar", "hupd", "infocmp", "lcheck", "license", "locktable", "lpc", "lpq", "lpr", "lprm", "lscom", "machid", "mail", "oiinfo", "prefdump", "prefrestore", "prefvalue", "printerlog", "pstext", "psresolve", "psyslog", "serverlog", "slptool", "socket", "srvmsg", "srvutil", "start-helios", "stop-helios", "swho", "tic", "uniconv", and "uwhat".
6.2 HELIOSDIR/etc
The "HELIOSDIR/etc" directory contains additional installation files in the subdirectories "install", "uninstall", "licversions", "daily", "kernel", "modes", "pdfweb", "prefs", "runonce", "startstop", "termdefs", "terminfo", and "updates".
6.3 HELIOSDIR/etc/prefs
This directory contains the default preferences of each installed server which are loaded into the
"HELIOSDIR/var/conf/Preferences" file.6.4 HELIOSDIR/lib
"HELIOSDIR/lib" with its subdirectory "OpenImage" contains library files and other resources which are shared by all applications.
6.5 HELIOSDIR/public
The "HELIOSDIR/public" directory contains Mac and Windows applications in the directories "ReadMe", "Documentation", "MacOS" and "Windows". The applications are available to remote Mac/Windows users via the "HELIOS Applications" volume (Mac) and "HELIOS_APPS" directory (Windows).
6.6 HELIOSDIR/sbin
The "HELIOSDIR/sbin" directory contains applications which are automatically started by the server: "uninstall", "balanceif", "cloneif", "heliosgroups", "demouser", "authsrv", "migrate", "demovol", "homevol", "diskif", "rebuild", "getlocalfs", "heladmsrv", "notifysrv", "helios.daily", "holdif", "ifstat", "logrotate", "lpd", "pcap", "psof", "setmode", "desksrv", "shmif", "slpsrv", "srvsrv", "tcpif", "timeif", "update-versions", "yp-update", and "exechelper" (Mac OS X only!). Some of them, such as "slpsrv" or "srvsrv" run permanently in the background,
Important: Except for the "uninstall" script, the files in the "HELIOSDIR/sbin" directory should never be started manually.6.7 HELIOSDIR/var
The "HELIOSDIR/var" directory contains all configuration data and is the only subdirectory in "HELIOSDIR/" that is "read-write".
The "adm" directory contains server and printer accounting files of today and the last six days.
"cmaps" contains character translation mapping tables, e.g.: iso7, iso8, epson, hp, etc.
The "ICC-Profiles" directory, which is available as a shared network volume, contains subdirectories for scanner, monitor and printer profiles as well as the index file "!profile.inx" which lists all profiles.
"OpenImage" usually contains no permanent data. OpenImage specific processes store files temporarily in this directory and delete them when they have accomplished their tasks.
The "run" directory contains version and other utility files.
"tmp" usually contains no permanent data. Some products, such as ImageServer, store files temporarily in this directory and delete them when they have accomplished their tasks.
The "settings" directory contains subdirectories which are meant as a server repository for PPDs, printer scripts, printer drivers, and Distiller settings. In order to make it available to all users on the network, this directory is published as a HELIOS volume. Additional subdirectories are created in "settings" if further HELIOS products are installed on the host, e.g. "WebShare".
For "conf" see chapter 6.8 "HELIOSDIR/var/conf" below.
6.8 HELIOSDIR/var/conf
The "conf" directory has the following content, on which we will have a more detailed look:
This file contains the access list with the IP addresses which are permitted to log on to, i.e. use, HELIOS services. You can modify the access list with HELIOS Admin (Settings > IP Access).
Per default (after installation), the "ipaccess" file provides no access restrictions. In order to set up access restrictions use HELIOS Admin as described above, or copy the content of the file "ipaccess.local" to "ipaccess".
To allow remote access to the LPD of a machine, independent of the entries in the main "ipacces" list, it is possible to create a "HELIOSDIR/var/conf/ipaccess.lpd" file which will only be used by the LPD daemon.
This file contains HELIOS software license(s) which can be seen, erased and added by use of the tools which are described in 4.4 "Licenses".
The file "passwd" contains a list of all HELIOS users on the system. An entry line in this file specifies for each user name and password in encrypted form.
HELIOS preferences are stored in this (binary) file. Preferences with default values, i.e. that have not been changed, do not appear in this file. The programs "prefdump", "prefrestore", and "prefvalue", which are explained in 8 "HELIOS utility programs", can be used to create and update this file. But we strongly recommend to change preference values with HELIOS Admin.
Each printer queue requires an entry in "printcap" to describe in detail the way in which the associated physical printer is connected.
This a typical "printcap" entry for a PAP printer:
6.9 HELIOSDIR/var/spool/dicts
The "dicts" directory contains the HELIOS PostScript dictionaries:
The dictionary for the "Linotype color separation" process is now incorporated in the printer interfaces and not contained in this directory anymore.
6.10 HELIOSDIR/var/spool/psfonts
The "psfonts" directory contains all PostScript (Type1 and Type3) fonts that were installed on the host via HELIOS Admin.
This file lists all installed fonts on the server.
6.11 HELIOSDIR/var/spool/qmeta
This directory contains the metadata for all existing printer queues which have been created on the server. The default queues are "hold" and "error". The directory of each printer queue contains amongst others the "FONTS" and "PPD" files. The "FONTS" file contains a list of all PostScript fonts, the "PPD" file the selected PPD for the specified printer queue installed on the server.
