NAME

ipsec barf - spew out collected IPsec debugging information
ipsec look - show minimal debugging information  

SYNOPSIS

ipsec barf [ --short ]

ipsec look  

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.

Look outputs a minimal subset of this, intended as a quick look at current connections and related information, in a somewhat less self-explanatory format optimized for terseness.

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.

Barf censors its output, replacing keys and secrets with brief checksums to avoid revealing sensitive information. Look output does not contain such 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.
