# #
# CONFIGURATION FILE FOR THE MOTSOGNIR GOPHER SERVER #
# #
##############################################################
## Server's hostname ##
# The hostname the gopher server is reachable at. This setting is highly
# recommended, because the gopher protocol is heavily relying on
# self-pointing links. If not declared, the server's IP address will be used
# instead.
#GopherHostname=gopher.example.com
## Gopher TCP port ##
# The TCP port on which the public Gopher server listens on.
# Usually, gopher servers are published on port 70. Default: 70.
GopherPort=70
## Bind on IP address ##
# Set this 'bind' parameter to the IP address you'd like Motsognir to listen
# on. Note, that this parameter must be either an IPv6 address, or an IPv4
# address written in IPv4-mapped IPv6 notation (for ex. "::FFFF:10.0.0.1").
# If not specified, Motsognir will listen on all available IP addresses.
# This setting might be useful if you have a multihomed server, and you would
# like to serve different content for each IP address.
# Examples:
# bind=2001:DB8:135:A0E3::2
# bind=::FFFF:192.168.0.3
bind=
## Disable IPv6 support ##
# Set this to 1 to DISABLE IPv6 support within Motsognir. Please note that
# when IPv6 is enabled (which is the default), Motsognir may or may not listen
# to both IPv4 and IPv6 sockets. This is somewhat of a mess, and it is related
# to how your operating system treats IPv6 sockets. Most sane operating
# systems support dual-stack sockets. In such environments, Motsognir will
1*A'
!#))
# open an IPv6 socket and mark it as "not-only-ipv6" (setting IPV6_BINDV6ONLY
# to false), thus instructing the operating system to accept both IPv4 and
# IPv6 packets on this socket. Unfortunately, some exotic systems are
# religiously against dual-stack sockets (as of 2019, I know about at least
# two such systems: OpenBSD and DragonFlyBSD). On these systems, an IPv6
# socket is unable to accept IPv4 packets, hence Motsognir ends up receiving
# exclusively IPv6 traffic. As a workaround for such systems, one should run
# two instances of Motsognir (one for each protocol). This means two separate
# configuration files: one with and one without the setting below being set.
disableipv6=0
## Root directory ##
# That's the local path to Gopher resources. Note, that if you use
# a chroot configuration, you must provide here the virtual path
# instead of the real one.
# The default path is /var/gopher/
GopherRoot=/var/gopher/
## Allowed public directories ##
# In specific situations, it may happen that you'd like to be able to serve
# files from outside of your gopher root (typically, if you used symlinks
# inside your gopher root, that points to other places of the file system).
# By default Motsognir won't allow such resources to be served, since requests
# that try to access anything outside of the gopher root are considered as
# potentially malicious. However, if you do want to serve content from outside
# your gopher root, then fill in below the list of directories that are
# allowed to be served. Items of this list should be separated by a ':' char.
# Example: PubDirList=/srv/files:/var/lib/stuff:/tmp
PubDirList=
## User home directories ##
# If you'd like to serve gopher content from user directories, using the
# classic /~user/ URL scheme, then define the user directories location here
# below. The configured location must contain a '%s' tag, which will be
# substituted with the username by motsognir. This must be an absolute path.
# If nothing is configured, then support for serving content from user
# directories won't be available. Example:
# UserDir=/home/%s/public_gopher/
UserDir=
## chroot configuration ##
# If you'd like to put Motsognir inside a chroot jail, configure here
# the chroot directory that shall be used.
# By default no chroot is used.
chroot=
## Plugin ##
# Power-admins might want to craft some additional logic into Motsognir. This is
# possible using a 'plugin', ie. a simple application or php script that
# Motsognir will submit incoming queries to. The plugin can decide whether or
# not it wants to handle a given query (if not, then Motsognir will process it
# as usual. The queries that Motsognir will submit to the plugin can be filtered
# by using a 'PluginFilter'. This is a 'POSIX extended' regular expression that
# will be compared to every incoming queries, and only matching queries are
# submitted to the plugin. Read more in the manual.
15A'
!#))
Plugin=
PluginFilter=
## Paranoid mode ##
# For paranoidal security, you might want to enable "Paranoid mode". In this
# mode, Motsognir accepts to serve only files with permissions set to "world
# readable".
# Possible values: 0 (disabled) or 1 (enabled). Disabled by default.
ParanoidMode=0
## Activate the verbose mode ##
# Here you can enable/disable the verbose mode. In verbose mode,
# Motsognir will generate much more logs. This is useful only in
# debug situations.
# Possible values: 0 (disabled) or 1 (enabled). Disabled by default.
Verbose=0
## CGI support ##
# The line below enables/disables CGI support. Read the manual
# for details.
# Possible values: 0 (disabled) or 1 (enabled). Disabled by default.
GopherCgiSupport=0
## PHP support ##
# There you can enable PHP support.
# Possible values: 0 (disabled) or 1 (enabled). Disabled by default.
GopherPhpSupport=0
## Sub-gophermap scripts ##
# If you'd like to use sub-gophermap scripts in your gophermaps, set
# SubGophermaps.
# Possible values: 0 (disabled) or 1 (enabled). Disabled by default.
SubGophermaps=0
## Secondary URL-delimiting char
# By default, only the '?' char is recognized as a delimiter between an
# object and the query that must be run on the object. With this parameter,
# you can define an additional character that will be equivalent to '?'. This
# character must be provided in a numerical form, as an ASCII value.
# Example for the hash (#) character:
# SecUrlDelim=35
SecUrlDelim=
## Run as another user ##
# If you start motsognir under a root account, you might want to configure
# it so it drops root privileges as soon as it doesn't need them anymore and
# switches to another user. This is recommended for increased security,
# unless you already run Motsognir as a non-root user.
# To do so, provide here the username of the user that Motsognir should run
# as. Default = no value.
RunAsUser=
## Default gophermap #
# If you wish that your server would use a default gophermap when displaying
# a directory that do not have a gophermap, you can specify here a path to
18A'
!#))
# the gophermap file you'd like to use.
DefaultGophermap=
## HTTP error file
# When Motsognir receives a HTTP request, it answers with a HTTP error,
# along with a html message indicating why it is wrong. If you'd like to use
# a custom html file, you can set it here. Note, that the specified file is
# loaded when Motsognir's starts. If you modify the file afterwards, you'll
# need to restart the Motsognir process for the file to be reloaded.
# Example: HttpErrFile=/etc/motsognir-httperr.html
HttpErrFile=
## Caps.txt support ##
# Caps.txt is a specific file-like selector, which allows a gopher client to
# know more about the server's implementation (for example what the path's
# delimiter is, where is the server located, etc). When enabled, Motsognir
# will answer with caps-compatible data to requests for "/caps.txt".
# Caps support is enabled by default (CapsSupport=1).
CapsSupport=1
## Caps additionnal informations ##
# If Caps support is enabled, you can specify there some additional
# informations about your server. These informations will be served
# to gopher clients along with the CAPS.TXT data.
# Example:
# CapsServerArchitecture=Linux/i386
# CapsServerDescription=This is my server
# CapsServerGeolocationString=Dobrogoszcz, Poland
# CapsServerDefaultEncoding=UTF-8
CapsServerArchitecture=
CapsServerDescription=
CapsServerGeolocationString=
CapsServerDefaultEncoding=
## Extension to filetype mapping ##
# Motsognir looks at file's extensions to advertise the proper gopher resource
# type. If the default mapping is not suiting you, you can load a custom
# mapping using a separate configuration file called an 'extmap', and declare
# it below. The extmap file is a simple text file, where every line provides
# a mapping for a single file extension, in such format:
# txt:0
# pdf:P
# gif:g
# Note: Extensions in the extmap file are processes in a case-insensitive way.
ExtMapFile=
