NAME

       ipsec_barf - spew out collected IPsec debugging information

SYNOPSIS

       ipsec barf [--short --maxlines <100>]

DESCRIPTION

       Barf outputs (on standard output) a collection of debugging information (contents of files, selections from logs, etc.) related to the
       IPsec encryption/authentication system. It is primarily a convenience for remote debugging, a single command which packages up (and labels)
       all information that might be relevant to diagnosing a problem in IPsec.

       The --short option limits the length of the log portion of barf's output, which can otherwise be extremely voluminous if debug logging is
       turned on.

       --maxlines <100> option sets the length of some bits of information, currently netstat -rn. Useful on boxes where the routing table is
       thousands of lines long. Default is 100.

       Barf censors its output, replacing keys and secrets with brief checksums to avoid revealing sensitive information.

       Beware that the output of both commands is aimed at humans, not programs, and the output format is subject to change without warning.

       Barf has to figure out which files in /var/log contain the IPsec log messages. It looks for KLIPS and general log messages first in
       messages and syslog, and for Pluto messages first in secure, auth.log, and debug. In both cases, if it does not find what it is looking for
       in one of those "likely" places, it will resort to a brute-force search of most (non-compressed) files in /var/log.

FILES

	   /proc/net/*
	   /var/log/*
	   /etc/ipsec.conf
	   /etc/ipsec.secrets

BUGS

       Barf uses heuristics to try to pick relevant material out of the logs, and relevant messages which are not labelled with any of the tags
       that barf looks for will be lost. We think we've eliminated the last such case, but one never knows...

       Finding updown scripts (so they can be included in output) is, in general, difficult.  Barf uses a very simple heuristic that is easily
       fooled.

       The brute-force search for the right log files can get expensive on systems with a lot of clutter in /var/log.

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

       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.

FILES

       /proc/net/ipsec_klipsdebug, /usr/local/bin/ipsec

BUGS

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