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

Synopsis

ipsec klipsdebug
cat/proc/net/ipsec_klipsdebug

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.
