ipsec - invoke IPsec utilities
ipsec command [ argument ...]
Ipsec invokes any of several utilities involved in controlling the
IPsec encryption/authentication system, running the specified command
with the specified arguments as if it had been invoked directly. This
largely eliminates possible name collisions with other software, and
also permits some centralized services.
In particular, ipsec supplies the invoked command with a suitable PATH
environment variable, and also provides IPSEC_DIR, IPSEC_CONFS, and
IPSEC_VERSION environment variables, containing respectively the full
pathname of the directory where the IPsec utilities are stored, the
full pathname of the directory where the configuration files live, and
the IPsec version number.
ipsec --help lists the available commands. Most have their own manual
pages, e.g. ipsec_auto(8) for auto.
ipsec --version outputs version information about Linux FreeS/WAN. A
version code of the form ‘‘Uxxx/Kyyy’’ indicates that the user-level
utilities are version xxx but the kernel portion appears to be version
yyy (this form is used only if the two disagree).
ipsec --versioncode outputs just the version code, with none of
--version’s supporting information, for use by scripts.
ipsec --copyright supplies boring copyright details.
ipsec --directory reports where ipsec thinks the IPsec utilities are
ipsec --confdir reports where ipsec thinks the IPsec configuration
files are stored.
/usr/lib/ipsec usual utilities directory
The following environment variables control where FreeS/WAN finds its
components. The ipsec command sets them if they are not already set.
IPSEC_EXECDIR directory containing published commands
IPSEC_LIBDIR directory containing internal executables
IPSEC_SBINDIR directory containing ipsec command
IPSEC_CONFS directory containing configuration files
ipsec.conf(5), ipsec.secrets(5), ipsec_auto(8), ipsec_barf(8),
ipsec_setup(8), ipsec_showdefaults(8), ipsec_showhostkey(8)

The provision of centralized services, while convenient, does
compromise the original concept of making the utilities invocable
directly as well as via ipsec.
