DESCRIPTION

19       Klipsdebug sets and clears flags that control various parts of the
20       debugging output of Klips (the kernel portion of FreeS/WAN IPSEC). The
21       form with no additional arguments lists the present contents of
22       /proc/net/ipsec_klipsdebug. The --set form turns the specified flag on,
23       while the --clear form turns the specified flag off. The --all form
24       turns all flags on except verbose, while the --none form turns all
25       flags off.
26
27       The current flag names are:
28
29       tunnel
30           tunnelling code
31
32       tunnel-xmit
33           tunnelling transmit only code
34
35       pfkey
36           userspace communication code
37
38       xform
39           transform selection and manipulation code
40
41       eroute
42           eroute table manipulation code
43
44       spi
45           SA table manipulation code
46
47       radij
48           radij tree manipulation code
49
50       esp
51           encryptions transforms code
52
53       ah
54           authentication transforms code rcv receive code
55
56       ipcomp
57           ip compression transforms code
58
59       verbose
60           give even more information, BEWARE: a)this will print
61           authentication and encryption keys in the logs b)this will probably
62           trample the 4k kernel printk buffer giving inaccurate output
63
64       All Klips debug output appears as kernel.info messages to syslogd(8).
65       Most systems are set up to log these messages to /var/log/messages.
66       Beware that klipsdebug --all produces a lot of output and the log file
67       will grow quickly.
68
69       The file format for /proc/net/ipsec_klipsdebug is discussed in
70       ipsec_klipsdebug(5).
71

EXAMPLES

73       klipsdebug --all
74           turns on all KLIPS debugging except verbose.
75
76       klipsdebug --clear tunnel
77           turns off only the tunnel debugging messages.

BUGS

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