The format of /proc/net/ipsec_tncfg is discussedin ipsec_tncfg(5).The.B \-\-attachform attaches the.I virtualinterface to the.I physicalone.The.B \-\-detachform detaches the.I virtualinterface from whichever physical interface it is attached to.The.B \-\-clearform clears all the.I virtualinterfaces from whichever physical interfaces they were attached to..PPVirtual interfaces typically have names like.BR ipsec0 ,while physical interfaces typically have names like.B eth0or.BR ppp0 ..SH EXAMPLES.TP.B ipsec tncfg \-\-attach \-\-virtual ipsec0 \-\-physical eth0attaches the.B ipsec0virtual device to the.B eth0physical device..LP.SH "FILES"/proc/net/ipsec_tncfg, /usr/local/bin/ipsec.SH "SEE ALSO"ipsec(8), ipsec_manual(8), ipsec_eroute(8), ipsec_spi(8),ipsec_spigrp(8), ipsec_klipsdebug(8), ipsec_tncfg(5).SH HISTORYWritten for the Linux FreeS/WAN project<http://www.freeswan.org/>by Richard Guy Briggs..\".\" $Log: tncfg.8,v $.\" Revision 1.15  2002/04/24 07:35:41  mcr.\" Moved from ./klips/utils/tncfg.8,v.\".\" Revision 1.14  2000/09/12 13:09:04  rgb.\" Fixed real/physical discrepancy between tncfg.8 and tncfg.c..\".\" Revision 1.13  2000/06/30 18:21:55  rgb.\" Update SEE ALSO sections to include ipsec_version(5) and ipsec_pf_key(5).\" and correct FILES sections to no longer refer to /dev/ipsec which has.\" been removed since PF_KEY does not use it..\".\" Revision 1.12  2000/06/21 16:54:58  rgb.\" Added 'no additional args' text for listing contents of.\" /proc/net/ipsec_* files..\".\" Revision 1.11  1999/07/19 18:47:25  henry.\" fix slightly-misformed comments.\".\" Revision 1.10  1999/04/06 04:54:39  rgb.\" Fix/Add RCSID Id: and Log: bits to make PHMDs happy.
