ipsec_tncfg: manipulate KLIPS virtual interfaces

NAME

ipsec_tncfg - manipulate KLIPS virtual interfaces

SYNOPSIS

ipsec tncfg

ipsec tncfg --create virtual
ipsec tncfg --delete virtual
ipsec tncfg --attach --virtual virtual --physical physical
ipsec tncfg --detach --virtual virtual
ipsec tncfg --clear
ipsec tncfg --version
ipsec tncfg --help

KLIPS

Note that tncfg is only supported on the KLIPS stack which uses ipsecX interfaces bound to physical interfaces

DESCRIPTION

The purpose of tncfg is to attach/detach IPsec virtual interfaces (e.g. ipsec0) to/from physical interfaces (e.g. eth0) through which packets will be forwarded once processed by KLIPS.

When using the MAST stack, tncfg is used to create and delete virtual interfaces known as mastXXX. mast stands for Mooring and XXX.

The form with no additional arguments lists the contents of /proc/net/ipsec_tncfg. The format of /proc/net/ipsec_tncfg is discussed in ipsec_tncfg(5).

The --attach form attaches the virtual interface to the physical one.

The --detach form detaches the virtual interface from whichever physical interface it is attached to.

The --clear form clears all the virtual interfaces from whichever physical interfaces they were attached to.

Virtual interfaces typically have names like ipsec0 or mast0 while physical interfaces typically have names like eth0 or ppp0.

EXAMPLES

ipsec tncfg --create mast12

creates the mast12 device.

ipsec tncfg --create ipsec4

creates an ipsec4 device, but does not attach it.

ipsec tncfg --attach --virtual ipsec0 --physical eth0

attaches the ipsec0 virtual device to the eth0 physical device.
