NAME

6       ipsec_barf - spew out collected IPsec debugging information
7

SYNOPSIS

9       ipsec barf [--short]
10

DESCRIPTION

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 that 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       On systems with systemd, ipsec barf will look for logs using the
23       journalctl command. If the logfile= option is used, logs will also not
24       be found by the ipsec barf command.
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 general log messages first in messages and
34       syslog, and for Pluto messages first in secure, auth.log, and debug. In
35       both cases, if it does not find what it is looking for in one of those
36       “likely” places, it will resort to a brute-force search of most
37       (non-compressed) files in /var/log.

BUGS

50       Barf uses heuristics to try to pick relevant material out of the logs,
51       and relevant messages that 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.
