## NAME

ipsec setup - control IPsec subsystem

## SYNOPSIS

ipsec setup command

## DESCRIPTION

Setup controls the FreeS/WAN IPsec subsystem, including both the Klips kernel code and the Pluto key-negotiation daemon. (It is a synonym for the ``rc'' script for the subsystem; the system runs the equivalent of ipsec setup start at boot time, and ipsec setup stop at shutdown time, more or less.)

The action taken depends on the specific command, and on the contents of the config setup section of the IPsec configuration file (/etc/ipsec.conf, see ipsec.conf(5)). Current commands are:

start
  start Klips and Pluto, including setting up Klips to do crypto operations on the interface(s) specified in the configuration file, and (if the configuration file so specifies) setting up manually-keyed connections and/or asking Pluto to negotiate automatically-keyed connections to other security gateways
stop
  shut down Klips and Pluto, including tearing down all existing crypto connections
restart
  equivalent to stop followed by start
status
  report the status of the subsystem; normally just reports IPsec running and pluto pid nnn, or IPsec stopped, and exits with status 0, but will go into more detail (and exit with status 1) if something strange is found.

The stop operation tries to clean up properly even if assorted accidents have occurred, e.g. Pluto having died without removing its lock file. If stop discovers that the subsystem is (supposedly) not running, it will complain, but will do its cleanup anyway before exiting with status 1.

Although a number of configuration-file parameters influence setup's operations, the key one is the interfaces parameter, which must be right or chaos will ensue.

## FILES

/etc/rc.d/init.d/ipsec`` the script itself
/etc/init.d/ipsec`` alternate location for the script
/etc/ipsec.conf`` IPsec configuration file
/var/run/ipsec.info`` saved information
/proc/sys/net/ipv4/ip_forward`` forwarding control

## SEE ALSO

## DIAGNOSTICS

All output from the commands start and stop goes both to standard output and to syslogd(8), via logger(1). Selected additional information is logged only to syslogd(8).

## BUGS

Old versions of logger(1) inject spurious extra newlines onto standard output.
