-- $Id: ChangeLog file for knocker version 0.7.1 - released on 24 May 2002
-------------------------------------------------------------------------------
24 May 2002
- Modified knocker_led.c and knocker_led.h to let knocker build on non-linux
OS as well. (if linux/kd.h include is found NO_LED will be defined).
19 May 2002
- A --configure option was added. If knocker is executed with this option it
will ask a few questions so the user can configure it to its need.
It is currently possible to choose if or not to use colors, and actually
choose what color to use for a particular output. These settings are stored
int the ~/.knocker/knocker.conf file and can be manually changed by the
user.
- Fixed the wrong results output in the logfile. The total number of scanned
ports was reported as the total of the found open ports.
18 May 2002
- Unit knocker_conf was added. The code in this module will handle all the
stuffs relative to the kncoker's configuration file. This file (knocker.conf)
is automatically created everytime knocker is executed and it can't find its
.conf in the user ~/.knocker subdirectory.
13 May 2002
- --no-fency (-nf for short) option added. This switch tells knocker to show
the output in a "polite" way. All the lines and stuffs shown in the default
mode, will not be displayed using this option.
- Function knocker_term_set_color modified no to alter the console background
color. This makes knocker to work properly under X11 terminals. It doesn't
screw up colors anymore. (Works with transparent background terminals too).
25 April 2002
- Unit knocker_led added. The code in this unit will handle the keyboard
leds. The idea is to get the leds blinking while portscanning ...
The code is there and it works, but it is not active yet.
7 April 2002
- --last-host option added. This gets the last host name that was scanned.
28 March 2002
- Added the --last-scan option. This option tells knocker to perform again
the last port scan.
- The unit knocker_user was added. In this module goes all the code that has
to do with user relative functions and the knocker user dir.(ex ~/.knocker)
26 March 2002
- Changed the --quiet-mode option in --quiet and the corrispondent short
option -qm in -q
9 March 2002
- Fixed a serious bug that was preventing knocker to scan a number of ports
greater than 1023, all ports scanned after 1023 ports already scanned were
reported as CLOSED ! (Basically I was not closing the socket in the
knocker_core_portscan_tcp_connnect (...) function, so that after 1023 open
sockets the system was unable to open more of them).
- Fixed another bug that was causing knocker to segfault before exiting if a
hostname couldn't be resolved.
Thanks to Emmanuel Seyman for having reported these bugs.
8 March 2002
- Changed the --enable-logfile option in --logfile. This option now requires
a file name to be specified. Ex: knocker -H thehost --logfile log.txt
- Added code to manage the list of services (generated from the /etc/services
file) in the unit knocker_services to get the correct service name under
Win32 platfroms. The getservbyport function in the Winsock lib seems not to
work correctly.
- Added the --win32-frontend option and the relative code to work with the
knocker win32 frontend.
1 March 2002
- Added Win32 Winsock code to work natively on Windows platforms.
Knocker can now be builded natively on Win32 platforms.
- Added code to handle colored output under Win32 platforms in the unit
knocker_term. (using conio.h).
- Added a function (knocker_term_reset) to *Fix* the bug that caused knocker
not to reset to the console default colors at exit.
- Added a function (knocker_term_clear) to clear the screen when knocker is
started.
- Added a DevC++4 project file to build knocker under Win32s platforms using
the IDE/Compiler available at www.bloodshed.net
Information on how to build knocker with this IDE can be found in the file
README.Win32
- knocker.ico file added in the source distribution.
23 February 2002:
- Fixed the segmentation fault that was caused by starting knocker without
the --host or -H option. Now the program exits properly and prints an
error message to inform the user.
- Unit knocker_timer added. This module handles timing stuffs.
- The elapsed time is now counted in milliseconds rather than in seconds.
- If a wrong option is given as a knocker command line argument, the error
message now prints its name.
Ex: knocker --hast localhost
knocker: invalid argument given: '--hast'
17 February 2002:
- Knocker's output style & colors changed. I like it, but you might not, if
that's the case, please, let me know.
- Elapsed time since the begin of the port scan is now shown in the results.
- Module knocker_output added. All the boring fprintf(...) stuffs are now in
this unit. This makes the main knocker unit a bit cleaner.
- Code to output debug messages was added.
15 February 2002:
- Big portions of code rewritten from scratch.
- The TCP connect port scan code has been improved. The scan should be
faster now. (In the old code the host name was resolved for each port
to be scanned!) Damn it.
- knocker_core totally redesigned (and rewritten) to be more flexible
and versatile. Plans are to make it available as a library/DLL .
13 February 2002:
- Fixed a bug in the version 0.5.1 that made impossible to scan a host
starting knocker in the default mode Ex: knocker --host thehost
This caused knocker to quit without performing the port scan.
- Added header file definitions to prevent multiple file inclusion.
09 February 2002:
- An option to perform a portscan on a single port was added.
The option is --port or -P
- threads code removed (since it was quite buggie)
Threads support will be redesigned and reimplemented in the future.
- Fixed the total scanned ports result counting bug: knocker was not
displaying the correct number of the scanned ports.
Ex: for a scan from port 1 to port 1000 it was displaying 998 as
total resoult insted of 1000. That's now fixed.
Thanks to Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn@axis.com>
for reporting that.
- Fixed the bug that caused knocker to segfault when the log file couldn't
be open. The program now quits gracefully telling the user what's going on.
- Compilation is now done with the following flags -Wall -ansi -pedantic
- Module terminal.c renamed to knocker_term.c
06 January 2002:
- Added the following options:
1. --quiet-mode
With this option the program can be started in background so that
no output to the console is generated and the scan's results are
written to a log file. (knocker_scan.log)
Ex: knocker --host 192.168.0.1 --quiet-mode &
2. --enable-logfile
This option logs the scan results to a file (knocker_scan.log)
Console output is not disabled by this option.
3. --no-threads
If you experience problems running knocker with threads just
pass this option.
Ex: knocker --host 192.168.0.1 --no-threads
- Added modules knocker_log.c, knocker_log.h to support the new
file logging functions.
27 July 2001:
- Added colored output !
- Code to print colored output done.
- Added a "--no-colors" option to disabled colored output
- Man page updated with new the new option about colors.
26 July 2001:
- Begun to add the code to print colored output.
20 July 2001:
- Now knocker uses threads (linux pthreads) in the portscan loop.
- The port scan process can now be cancelled by pressing the "c" key.
- The number of total ports scanned is now correctly shown even if
the scan is cancelled.
- configure.in modified to use threads.
- Three functions added to support the use of threads.
16 July 2001:
- Now knocker attempts to resolve an host IP address before the port
scan is started. It aborts the scan if the host IP can't be resolved.
15 July 2001:
- Added a function in knocker_core.c to resolve hosts IP addresses.
08 July 2001:
- Initial release.
