IPSEC(8)

NAME
ipsec - invoke IPsec utilities

SYNOPSIS
ipsec command [ argument ...]

ipsec --help
ipsec --version
ipsec --versioncode
ipsec --copyright
ipsec --directory
ipsec --confdir

DESCRIPTION
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 stored.

ipsec --confdir reports where ipsec thinks the IPsec configuration files are stored.

FILES
/usr/lib/ipsec    usual utilities directory

ENVIRONMENT

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

Written for Linux FreeS/WAN <http://www.freeswan.org> by Henry Spencer.

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