NAME

ipsec_klipsdebug - set KLIPS and MAST debug features and level. Other stacks are not supported.

SYNOPSIS

ipsec klipsdebug: ipsec klipsdebug --set flagname; ipsec klipsdebug --clear flagname; ipsec klipsdebug --all; ipsec klipsdebug --none; ipsec klipsdebug --help; ipsec klipsdebug --version

DESCRIPTION

Klipsdebug

sets and clears flags that control various parts of the debugging output of Klips (the kernel portion of FreeS/WAN IPSEC). The form with no additional arguments lists the present contents of /proc/net/ipsec_klipsdebug. The --set form turns the specified flag on, while the --clear form turns the specified flag off. The --all form turns all flags on except verbose, while the --none form turns all flags off.

The current flag names are:

tunnel

: tunnelling code

tunnel-xmit

: tunnelling transmit only code

pfkey

: userspace communication code

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

: authentication transforms code rcv receive code

ipcomp

: ip compression transforms code

verbose

: give even more information, BEWARE: a)this will print authentication and encryption keys in the logs b)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. Beware that klipsdebug--all produces a lot of output and the log file will grow quickly.

The file format for /proc/net/ipsec_klipsdebug is discussed in ipsec_klipsdebug(5).

EXAMPLES

klipsdebug --all

: turns on all KLIPS debugging except verbose.

klipsdebug --clear tunnel

: turns off only the tunnel debugging messages.

BUGS

It really ought to be possible to set or unset selective combinations of flags.
