Выходные параметры (Output options)
-v[level], --verbose [level] (Increase or set verbosity level)
Increases the verbosity level, causing Nping to print more
information during its execution. There are 9 levels of
verbosity (-4 to 4). Every instance of -v increments the
verbosity level by one (from its default value, level 0).
Every instance of option -q decrements the verbosity level by
one. Alternatively you can specify the level directly, as in
-v3 or -v-1. These are the available levels:
Level -4
No output at all. In some circumstances you may not want
Nping to produce any output (like when one of your work
mates is watching over your shoulder). In that case level
-4 can be useful because although you won't see any
response packets, probes will still be sent.
Level -3
Like level -4 but displays fatal error messages so you
can actually see if Nping is running or it failed due to
some error.
Level -2
Like level -3 but also displays warnings and recoverable
errors.
Level -1
Displays traditional run-time information (version, start
time, statistics, etc.) but does not display sent or
received packets.
Level 0
This is the default verbosity level. It behaves like
level -1 but also displays sent and received packets and
some other important information.
Level 1
Like level 0 but it displays detailed information about
timing, flags, protocol details, etc.
Level 2
Like level 1 but displays very detailed information about
sent and received packets and other interesting
information.
Level 3
Like level 2 but also displays the raw hexadecimal dump
of sent and received packets.
Level 4 and higher
Same as level 3.
-q[level], --reduce-verbosity [level] (Decrease verbosity level)
Decreases the verbosity level, causing Nping to print less
information during its execution.
-d[level] (Increase or set debugging level)
When even verbose mode doesn't provide sufficient data for
you, debugging is available to flood you with much more! As
with the -v, debugging is enabled with a command-line flag -d
and the debug level can be increased by specifying it
multiple times. There are 7 debugging levels (0 to 6). Every
instance of -d increments debugging level by one. Provide an
argument to -d to set the level directly; for example -d4.
Debugging output is useful when you suspect a bug in Nping,
or if you are simply confused as to what Nping is doing and
why. As this feature is mostly intended for developers, debug
lines aren't always self-explanatory. You may get something
like
NSOCK (1.0000s) Callback: TIMER SUCCESS for EID 12; tcpconnect_event_handler(): Received callback of type TIMER with status SUCCESS
If you don't understand a line, your only recourses are to
ignore it, look it up in the source code, or request help
from the development list (nmap-dev). Some lines are
self-explanatory, but the messages become more obscure as the
debug level is increased. These are the available levels:
Level 0
Level 0. No debug information at all. This is the default
level.
Level 1
In this level, only very important or high-level debug
information will be printed.
Level 2
Like level 1 but also displays important or medium-level
debug information
Level 3
Like level 2 but also displays regular and low-level
debug information.
Level 4
Like level 3 but also displays messages only a real Nping
freak would want to see.
Level 5
Like level 4 but it enables basic debug information
related to external libraries like Nsock.
Level 6
Like level 5 but it enables full, very detailed, debug
information related to external libraries like Nsock.
