WANem 2.1 (Virtual Machine branch)
11-21-2008
WANem can be used to emulate wide area networkconditions in a LAN environment. It can emulatenetwork characteristics like Bandwidth, latency,loss, disconnection, duplication, reordering,asymmetric networks, etc. It is distributed in theform of a bootable CD.|

IPSEC_TNCFG(8) Executable programs IPSEC_TNCFG(8) 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. FILES
