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

12 Barf outputs (on standard output) a collection of debugging information
13 (contents of files, selections from logs, etc.) related to the IPsec
14 encryption/authentication system. It is primarily a convenience for
15 remote debugging, a single command which packages up (and labels) all
16 information that might be relevant to diagnosing a problem in IPsec.
17
18 The --short option limits the length of the log portion of barf´s
19 output, which can otherwise be extremely voluminous if debug logging is
20 turned on.
21
22 --maxlines <100> option sets the length of some bits of information,
23 currently netstat -rn. Useful on boxes where the routing table is
24 thousands of lines long. Default is 100.
25
26 Barf censors its output, replacing keys and secrets with brief
27 checksums to avoid revealing sensitive information.
28
29 Beware that the output of both commands is aimed at humans, not
30 programs, and the output format is subject to change without warning.
31
32 Barf has to figure out which files in /var/log contain the IPsec log
33 messages. It looks for KLIPS and general log messages first in messages
34 and syslog, and for Pluto messages first in secure, auth.log, and
35 debug. In both cases, if it does not find what it is looking for in one
36 of those “likely” places, it will resort to a brute-force search of
37 most (non-compressed) files in /var/log.

41 /var/log/*

43 /etc/ipsec.secrets

50 Barf uses heuristics to try to pick relevant material out of the logs,
51 and relevant messages which are not labelled with any of the tags that
52 barf looks for will be lost. We think we´ve eliminated the last such
53 case, but one never knows...
54
55 Finding updown scripts (so they can be included in output) is, in
56 general, difficult. Barf uses a very simple heuristic that is easily
57 fooled.
58
59 The brute-force search for the right log files can get expensive on
60 systems with a lot of clutter in /var/log.
