ipsec_klipsdebug list KLIPS (kernel IPSEC support) debug features and level

## DESCRIPTION

`/proc/net/ipsec_klipsdebug` lists flags that control various parts of the debugging output of KLIPS and MAST, two of the IPsec stacks supported by Libreswan. At this point it is a read-only file.

A table entry consists of:

+

  a KLIPS debug variable

+

  a '=' separator for visual and automated parsing between the variable name and its current value

+

  hexadecimal bitmap of variable's flags.

The variable names roughly describe the scope of the debugging variable. Currently, no flags are documented or individually accessible yet except tunnel-xmit.

The variable names are:

tunnel

  tunnelling code

netlink

  userspace communication code (obsolete)

xform

  transform selection and manipulation code

eroute

  eroute table manipulation code

spi

  SA table manipulation code

radij

  radij tree manipulation code

esp

  encryptions transforms code

ah

  authentication transforms code

rcv

  receive code

ipcomp

  ip compression transforms code

verbose

  give even more information, beware this will probably trample the 4k kernel printk buffer giving inaccurate output

All KLIPS debug output appears as kernel.info messages to syslogd 8. Most systems are set up to log these messages to `/var/log/messages`.

## EXAMPLES

debug_tunnel=00000010. debug_netlink=00000000. debug_xform=00000000. debug_eroute=00000000. debug_spi=00000000. debug_radij=00000000. debug_esp=00000000. debug_ah=00000000. debug_rcv=00000000. debug_pfkey=ffffffff.

means that one tunnel flag has been set (tunnel-xmit), full pfkey sockets debugging has been set and everything else is not set.
