strongswan.conf¶

Please note: This page documents the configuration options of the most current release. Therefore, you should always consult the strongswan.conf(5) man page that comes with the release you are using to confirm which options are actually available.

Overview¶

While the ipsec.conf configuration file is well suited to define IPsec related configuration parameters, it is not useful for other strongSwan applications to read options from this file. The file is hard to parse and only ipsec starter is capable of doing so. As the number of components of the strongSwan project is continually growing, we needed a more flexible configuration file that is easy to extend and can be used by all components. The new configuration format consists of hierarchical sections and a list of key/value pairs in each section. Starting with the strongSwan 4.2.1 release, a default strongswan.conf file is installed in your sysconfdir, e.g. /etc/strongswan.conf.

Syntax¶

Each section has a name, followed by C-Style curly brackets defining the sections body. Each section body contains a set of subsections and key/value pairs:

settings := (section|keyvalue)*
section  := name { settings }
keyvalue := key = value\n

Values must be terminated by a newline. Comments are possible using the #-character, but be careful: The parser implementation is currently limited and does not like braces in comments. Section names and keys may contain any printable character except:

. { } # \n \t space

An example might look like this:

a = b
section-one {
  somevalue = asdf
  subsection {
    othervalue = xxx
  }
  # yei, a comment 
  yetanother = zz
}
section-two {
  x = 12
}

Indentation is optional, you may use tabs or spaces.

Including files¶

Version 4.5.1 introduced the include statement which allows to include other files into strongswan.conf, e.g.

include /some/path/*.conf

If the file name is not an absolute path, it is considered to be relative to the directory of the file containing the
include statement. The file name may include shell wildcards. Also, such inclusions can be nested.

Sections loaded from the included files extend previously loaded sections; already existing values are replaced.
It is important to note that settings are added relative to the section the include statement is in.

As an example, the following three files result in the same final config as the one given above:

a = b
section-one {
    somevalue = before include
    include include.conf
}
include other.conf

include.conf:

# settings loaded from this file are added to section-one
# the following replaces the previous value
somevalue = asdf
subsection {
    othervalue = yyy
}
yetanother = zz

other.conf:

# this extends section-one and subsection
section-one {
    subsection {
        # this replaces the previous value
        othervalue = xxx
    }
}
section-two {
    x = 12
}

Reading values¶

The config file is read by libstrongswan during library initialization. Values are accessed using a dot-separated section list and a key:
Accessing section-one.subsection.othervalue will return xxx.

Have a look at the settings interface (source:src/libstrongswan/settings.h) to learn about the details.
