## NAME

ipsec klipsdebug - set KLIPS (kernel IPSEC support) debug features and level

## 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
ah
  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.
