* Only the first 15 games in progress are shown on the games in progress

screen.

* Since virus kept calling alarm() on itself, I removed SIGALRM handling

altogether, which breaks occasional refresh of the bottom status line.

I don't consider this a huge bug, but if one day I, or someone else,
|

gets really bored, the full solution to this would be to bring back
|

|
the virus signal handling, and just clear the alarm calls before exiting

and going back to dgamelaunch code (or clear the alarm() handlers).

GNU GENERAL PUBLIC LICENSE
|
||||||
|
Version 2, June 1991
|
||||||
|
|
||||||
|
Copyright (C) 2001-2003 M. Drew Streib
|
||||||
|
Everyone is permitted to copy and distribute verbatim copies
|
||||||
|
of this license document, but changing it is not allowed.
|
||||||
|
|
||||||
|
Preamble
|
||||||
|
|
||||||
|
The licenses for most software are designed to take away your
|
||||||
|
freedom to share and change it. By contrast, the GNU General Public
|
||||||
|
License is intended to guarantee your freedom to share and change free
|
||||||
|
software--to make sure the software is free for all its users. This
|
||||||
|
General Public License applies to most of the Free Software
|
||||||
|
Foundation's software and to any other program whose authors commit to
|
||||||
|
using it. (Some other Free Software Foundation software is covered by
|
||||||
|
the GNU Library General Public License instead.) You can apply it to
|
||||||
|
your programs, too.
|
||||||
|
|
||||||
|
When we speak of free software, we are referring to freedom, not
|
||||||
|
price. Our General Public Licenses are designed to make sure that you
|
||||||
|
have the freedom to distribute copies of free software (and charge for
|
||||||
|
this service if you wish), that you receive source code or can get it
|
||||||
|
if you want it, that you can change the software or use pieces of it
|
||||||
|
in new free programs; and that you know you can do these things.
|
||||||
|
|
||||||
|
To protect your rights, we need to make restrictions that forbid
|
||||||
|
anyone to deny you these rights or to ask you to surrender the rights.
|
||||||
|
These restrictions translate to certain responsibilities for you if you
|
||||||
|
distribute copies of the software, or if you modify it.
|
||||||
|
|
||||||
|
For example, if you distribute copies of such a program, whether
|
||||||
|
gratis or for a fee, you must give the recipients all the rights that
|
||||||
|
you have. You must make sure that they, too, receive or can get the
|
||||||
|
source code. And you must show them these terms so they know their
|
||||||
|
rights.
|
||||||
|
|
||||||
|
We protect your rights with two steps: (1) copyright the software, and
|
||||||
|
(2) offer you this license which gives you legal permission to copy,
|
||||||
|
distribute and/or modify the software.
|
||||||
|
|
||||||
|
Also, for each author's protection and ours, we want to make certain
|
||||||
|
that everyone understands that there is no warranty for this free
|
||||||
|
software. If the software is modified by someone else and passed on, we
|
||||||
|
want its recipients to know that what they have is not the original, so
|
||||||
|
that any problems introduced by others will not reflect on the original
|
||||||
|
authors' reputations.
|
||||||
|
|
||||||
|
Finally, any free program is threatened constantly by software
|
||||||
|
patents. We wish to avoid the danger that redistributors of a free
|
||||||
|
program will individually obtain patent licenses, in effect making the
|
||||||
|
program proprietary. To prevent this, we have made it clear that any
|
||||||
|
patent must be licensed for everyone's free use or not licensed at all.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and
|
||||||
|
modification follow.
|
||||||
|
|
||||||
|
GNU GENERAL PUBLIC LICENSE
|
||||||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||||
|
|
||||||
|
0. This License applies to any program or other work which contains
|
||||||
|
a notice placed by the copyright holder saying it may be distributed
|
||||||
|
under the terms of this General Public License. The "Program", below,
|
||||||
|
refers to any such program or work, and a "work based on the Program"
|
||||||
|
means either the Program or any derivative work under copyright law:
|
||||||
|
that is to say, a work containing the Program or a portion of it,
|
||||||
|
either verbatim or with modifications and/or translated into another
|
||||||
|
language. (Hereinafter, translation is included without limitation in
|
||||||
|
the term "modification".) Each licensee is addressed as "you".
|
||||||
|
|
||||||
|
Activities other than copying, distribution and modification are not
|
||||||
|
covered by this License; they are outside its scope. The act of
|
||||||
|
running the Program is not restricted, and the output from the Program
|
||||||
|
is covered only if its contents constitute a work based on the
|
||||||
|
Program (independent of having been made by running the Program).
|
||||||
|
Whether that is true depends on what the Program does.
|
||||||
|
|
||||||
|
1. You may copy and distribute verbatim copies of the Program's
|
||||||
|
source code as you receive it, in any medium, provided that you
|
||||||
|
conspicuously and appropriately publish on each copy an appropriate
|
||||||
|
copyright notice and disclaimer of warranty; keep intact all the
|
||||||
|
notices that refer to this License and to the absence of any warranty;
|
||||||
|
and give any other recipients of the Program a copy of this License
|
||||||
|
along with the Program.
|
||||||
|
|
||||||
|
You may charge a fee for the physical act of transferring a copy, and
|
||||||
|
you may at your option offer warranty protection in exchange for a fee.
|
||||||
|
|
||||||
|
2. You may modify your copy or copies of the Program or any portion
|
||||||
|
of it, thus forming a work based on the Program, and copy and
|
||||||
|
distribute such modifications or work under the terms of Section 1
|
||||||
|
above, provided that you also meet all of these conditions:
|
||||||
|
|
||||||
|
a) You must cause the modified files to carry prominent notices
|
||||||
|
stating that you changed the files and the date of any change.
|
||||||
|
|
||||||
|
b) You must cause any work that you distribute or publish, that in
|
||||||
|
whole or in part contains or is derived from the Program or any
|
||||||
|
part thereof, to be licensed as a whole at no charge to all third
|
||||||
|
parties under the terms of this License.
|
||||||
|
|
||||||
|
c) If the modified program normally reads commands interactively
|
||||||
|
when run, you must cause it, when started running for such
|
||||||
|
interactive use in the most ordinary way, to print or display an
|
||||||
|
announcement including an appropriate copyright notice and a
|
||||||
|
notice that there is no warranty (or else, saying that you provide
|
||||||
|
a warranty) and that users may redistribute the program under
|
||||||
|
these conditions, and telling the user how to view a copy of this
|
||||||
|
License. (Exception: if the Program itself is interactive but
|
||||||
|
does not normally print such an announcement, your work based on
|
||||||
|
the Program is not required to print an announcement.)
|
||||||
|
|
||||||
|
These requirements apply to the modified work as a whole. If
|
||||||
|
identifiable sections of that work are not derived from the Program,
|
||||||
|
and can be reasonably considered independent and separate works in
|
||||||
|
themselves, then this License, and its terms, do not apply to those
|
||||||
|
sections when you distribute them as separate works. But when you
|
||||||
|
distribute the same sections as part of a whole which is a work based
|
||||||
|
on the Program, the distribution of the whole must be on the terms of
|
||||||
|
this License, whose permissions for other licensees extend to the
|
||||||
|
entire whole, and thus to each and every part regardless of who wrote it.
|
||||||
|
|
||||||
|
Thus, it is not the intent of this section to claim rights or contest
|
||||||
|
your rights to work written entirely by you; rather, the intent is to
|
||||||
|
exercise the right to control the distribution of derivative or
|
||||||
|
collective works based on the Program.
|
||||||
|
|
||||||
|
In addition, mere aggregation of another work not based on the Program
|
||||||
|
with the Program (or with a work based on the Program) on a volume of
|
||||||
|
a storage or distribution medium does not bring the other work under
|
||||||
|
the scope of this License.
|
||||||
|
|
||||||
|
3. You may copy and distribute the Program (or a work based on it,
|
||||||
|
under Section 2) in object code or executable form under the terms of
|
||||||
|
Sections 1 and 2 above provided that you also do one of the following:
|
||||||
|
|
||||||
|
a) Accompany it with the complete corresponding machine-readable
|
||||||
|
source code, which must be distributed under the terms of Sections
|
||||||
|
1 and 2 above on a medium customarily used for software interchange; or,
|
||||||
|
|
||||||
|
b) Accompany it with a written offer, valid for at least three
|
||||||
|
years, to give any third party, for a charge no more than your
|
||||||
|
cost of physically performing source distribution, a complete
|
||||||
|
machine-readable copy of the corresponding source code, to be
|
||||||
|
distributed under the terms of Sections 1 and 2 above on a medium
|
||||||
|
customarily used for software interchange; or,
|
||||||
|
|
||||||
|
c) Accompany it with the information you received as to the offer
|
||||||
|
to distribute corresponding source code. (This alternative is
|
||||||
|
allowed only for noncommercial distribution and only if you
|
||||||
|
received the program in object code or executable form with such
|
||||||
|
an offer, in accord with Subsection b above.)
|
||||||
|
|
||||||
|
The source code for a work means the preferred form of the work for
|
||||||
|
making modifications to it. For an executable work, complete source
|
||||||
|
code means all the source code for all modules it contains, plus any
|
||||||
|
associated interface definition files, plus the scripts used to
|
||||||
|
control compilation and installation of the executable. However, as a
|
||||||
|
special exception, the source code distributed need not include
|
||||||
|
anything that is normally distributed (in either source or binary
|
||||||
|
form) with the major components (compiler, kernel, and so on) of the
|
||||||
|
operating system on which the executable runs, unless that component
|
||||||
|
itself accompanies the executable.
|
||||||
|
|
||||||
|
If distribution of executable or object code is made by offering
|
||||||
|
access to copy from a designated place, then offering equivalent
|
||||||
|
access to copy the source code from the same place counts as
|
||||||
|
distribution of the source code, even though third parties are not
|
||||||
|
compelled to copy the source along with the object code.
|
||||||
|
|
||||||
|
4. You may not copy, modify, sublicense, or distribute the Program
|
||||||
|
except as expressly provided under this License. Any attempt
|
||||||
|
otherwise to copy, modify, sublicense or distribute the Program is
|
||||||
|
void, and will automatically terminate your rights under this License.
|
||||||
|
However, parties who have received copies, or rights, from you under
|
||||||
|
this License will not have their licenses terminated so long as such
|
||||||
|
parties remain in full compliance.
|
||||||
|
|
||||||
|
5. You are not required to accept this License, since you have not
|
||||||
|
signed it. However, nothing else grants you permission to modify or
|
||||||
|
distribute the Program or its derivative works. These actions are
|
||||||
|
prohibited by law if you do not accept this License. Therefore, by
|
||||||
|
modifying or distributing the Program (or any work based on the
|
||||||
|
Program), you indicate your acceptance of this License to do so, and
|
||||||
|
all its terms and conditions for copying, distributing or modifying
|
||||||
|
the Program or works based on it.
|
||||||
|
|
||||||
|
6. Each time you redistribute the Program (or any work based on the
|
||||||
|
Program), the recipient automatically receives a license from the
|
||||||
|
original licensor to copy, distribute or modify the Program subject to
|
||||||
|
these terms and conditions. You may not impose any further
|
||||||
|
restrictions on the recipients' exercise of the rights granted herein.
|
||||||
|
You are not responsible for enforcing compliance by third parties to
|
||||||
|
this License.
|
||||||
|
|
||||||
|
7. If, as a consequence of a court judgment or allegation of patent
|
||||||
|
infringement or for any other reason (not limited to patent issues),
|
||||||
|
conditions are imposed on you (whether by court order, agreement or
|
||||||
|
otherwise) that contradict the conditions of this License, they do not
|
||||||
|
excuse you from the conditions of this License. If you cannot
|
||||||
|
distribute so as to satisfy simultaneously your obligations under this
|
||||||
|
License and any other pertinent obligations, then as a consequence you
|
||||||
|
may not distribute the Program at all. For example, if a patent
|
||||||
|
license would not permit royalty-free redistribution of the Program by
|
||||||
|
all those who receive copies directly or indirectly through you, then
|
||||||
|
the only way you could satisfy both it and this License would be to
|
||||||
|
refrain entirely from distribution of the Program.
|
||||||
|
|
||||||
|
If any portion of this section is held invalid or unenforceable under
|
||||||
|
any particular circumstance, the balance of the section is intended to
|
||||||
|
apply and the section as a whole is intended to apply in other
|
||||||
|
circumstances.
|
||||||
|
|
||||||
|
It is not the purpose of this section to induce you to infringe any
|
||||||
|
patents or other property right claims or to contest validity of any
|
||||||
|
such claims; this section has the sole purpose of protecting the
|
||||||
|
integrity of the free software distribution system, which is
|
||||||
|
implemented by public license practices. Many people have made
|
||||||
|
generous contributions to the wide range of software distributed
|
||||||
|
through that system in reliance on consistent application of that
|
||||||
|
system; it is up to the author/donor to decide if he or she is willing
|
||||||
|
to distribute software through any other system and a licensee cannot
|
||||||
|
impose that choice.
|
||||||
|
|
||||||
|
This section is intended to make thoroughly clear what is believed to
|
||||||
|
be a consequence of the rest of this License.
|
||||||
|
|
||||||
|
8. If the distribution and/or use of the Program is restricted in
|
||||||
|
certain countries either by patents or by copyrighted interfaces, the
|
||||||
|
original copyright holder who places the Program under this License
|
||||||
|
may add an explicit geographical distribution limitation excluding
|
||||||
|
those countries, so that distribution is permitted only in or among
|
||||||
|
countries not thus excluded. In such case, this License incorporates
|
||||||
|
the limitation as if written in the body of this License.
|
||||||
|
|
||||||
|
9. The Free Software Foundation may publish revised and/or new versions
|
||||||
|
of the General Public License from time to time. Such new versions will
|
||||||
|
be similar in spirit to the present version, but may differ in detail to
|
||||||
|
address new problems or concerns.
|
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the Program
|
||||||
|
specifies a version number of this License which applies to it and "any
|
||||||
|
later version", you have the option of following the terms and conditions
|
||||||
|
either of that version or of any later version published by the Free
|
||||||
|
Software Foundation. If the Program does not specify a version number of
|
||||||
|
this License, you may choose any version ever published by the Free Software
|
||||||
|
Foundation.
|
||||||
|
|
||||||
|
10. If you wish to incorporate parts of the Program into other free
|
||||||
|
programs whose distribution conditions are different, write to the author
|
||||||
|
to ask for permission. For software which is copyrighted by the Free
|
||||||
|
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||||
|
make exceptions for this. Our decision will be guided by the two goals
|
||||||
|
of preserving the free status of all derivatives of our free software and
|
||||||
|
of promoting the sharing and reuse of software generally.
|
||||||
|
|
||||||
|
NO WARRANTY
|
||||||
|
|
||||||
|
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||||
|
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||||
|
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||||
|
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||||
|
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||||
|
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||||
|
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||||
|
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||||
|
REPAIR OR CORRECTION.
|
||||||
|
|
||||||
|
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||||
|
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||||
|
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||||
|
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||||
|
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||||
|
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||||
|
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||||
|
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||||
|
POSSIBILITY OF SUCH DAMAGES.
|
||||||
|
|
||||||
|
END OF TERMS AND CONDITIONS
|
||||||
|
|
||||||
|
Appendix: How to Apply These Terms to Your New Programs
|
||||||
|
|
||||||
|
If you develop a new program, and you want it to be of the greatest
|
||||||
|
possible use to the public, the best way to achieve this is to make it
|
||||||
|
free software which everyone can redistribute and change under these terms.
|
||||||
|
|
||||||
|
To do so, attach the following notices to the program. It is safest
|
||||||
|
to attach them to the start of each source file to most effectively
|
||||||
|
convey the exclusion of warranty; and each file should have at least
|
||||||
|
the "copyright" line and a pointer to where the full notice is found.
|
||||||
|
|
||||||
|
<one line to give the program's name and a brief idea of what it does.>
|
||||||
|
Copyright (C) 19yy <name of author>
|
||||||
|
|
||||||
|
This program is free software; you can redistribute it and/or modify
|
||||||
|
it under the terms of the GNU General Public License as published by
|
||||||
|
the Free Software Foundation; either version 2 of the License, or
|
||||||
|
(at your option) any later version.
|
||||||
|
|
||||||
|
This program is distributed in the hope that it will be useful,
|
||||||
|
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||||
|
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||||
|
GNU General Public License for more details.
|
||||||
|
|
||||||
|
You should have received a copy of the GNU General Public License
|
||||||
|
along with this program; if not, write to the Free Software
|
||||||
|
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
|
||||||
|
|
||||||
|
Also add information on how to contact you by electronic and paper mail.
|
||||||
|
|
||||||
|
If the program is interactive, make it output a short notice like this
|
||||||
|
when it starts in an interactive mode:
|
||||||
|
|
||||||
|
Gnomovision version 69, Copyright (C) 19yy name of author
|
||||||
|
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||||
|
This is free software, and you are welcome to redistribute it
|
||||||
|
under certain conditions; type `show c' for details.
|
||||||
|
|
||||||
|
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||||
|
parts of the General Public License. Of course, the commands you use may
|
||||||
|
be called something other than `show w' and `show c'; they could even be
|
||||||
|
mouse-clicks or menu items--whatever suits your program.
|
||||||
|
|
||||||
|
You should also get your employer (if you work as a programmer) or your
|
||||||
|
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||||
|
necessary. Here is a sample; alter the names:
|
||||||
|
|
||||||
|
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||||
|
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
||||||
|
proprietary programs. If your program is a subroutine library, you may
|
||||||
|
consider it more useful to permit linking proprietary applications with the
|
||||||
|
library. If this is what you want to do, use the GNU Library General
|
||||||
|
Public License instead of this License.

* Merry Christmas, dtype...

* Major cleanups - remove most uses of strcpy() and strcat(), except

in virus.c, replace with snprintf.

* Add support for mailing users while they are playing.

never happen anyway.

* Add a confirmation to the change password screen so people like me

don't change their passwords by accident all the time.

* Remove many unused variables and make some functions void because
|
||||||
|
they don't return anything.
|
||||||
|
* Add some function prototypes in dgamelaunch.c to quell warnings.
|
||||||
|
* Make some vars unsigned to quell warnings.
|
||||||
|
* 'capital letter. experimental' section made irrelevant by use of
|
||||||
|
tolower(3) around getch()
|
||||||
|
* Change big conditional block to use a switch.
|
||||||
|
* Replace a global with a static variable within the function.
|
||||||
|
|
||||||
|
1.3.10 (2003/10/22)
|
||||||
|
* Added a mode flag to the open call for inprogress lock files.
|
||||||
|
(jilles)
|
||||||
|
|
||||||
|
1.3.9 (2003/09/06)
|
||||||
|
* Fixed the bug where editing options file wouldn't work on same
|
||||||
|
session as registration.
|
||||||
|
* Changed ttyplay timeout to 20 minutes with a better error msg.
|
||||||
|
* Made a zero length response on registration just dump you
|
||||||
|
back to the main menu.
|
||||||
|
|
||||||
|
1.3.7 (2003/09/06)
|
||||||
|
* Fixed the infamous hlen bug! I was rewinding to the beginning
|
||||||
|
of payload, not header.
|
||||||
|
|
||||||
|
1.3.5 (2003/09/05)
|
||||||
|
* Returned SIGWINCH to defaults after exiting virus. This was
|
||||||
|
probably the screen resize crash bug. (maybe?)
|
||||||
|
|
||||||
|
1.3.1 (2003/08/30)
|
||||||
|
* First shot at an engine to strip out graphics sets. It is a lot
|
||||||
|
harder than I would have thought, but doable at a 99% or so
|
||||||
|
success rate, I think, which should at least allow people to
|
||||||
|
view games in other graphics sets somewhat.
|
||||||
|
|
||||||
|
1.2.22 (2003/08/29)
|
||||||
|
* Expanded README
|
||||||
|
* Hope to have caught the error in a partial read of the error.
|
||||||
|
|
||||||
|
1.2.21 (2003/08/28)
|
||||||
|
* Added a README since I noticed people were downloading this.
|
||||||
|
|
||||||
|
1.2.20 (2003/08/24)
|
||||||
|
* Added additional check on payload length. Just a sanity thing.
|
||||||
|
|
||||||
|
1.2.19 (2003/08/24)
|
||||||
|
* Fixed (hopefully) that nasty bug that occurs when a partial read
|
||||||
|
after header read returned, and caused the next header read to
|
||||||
|
basically read random data (and thus a random length).
|
||||||
|
|
||||||
|
1.2.18 (2003/08/14)
|
||||||
|
* After determining select() on files sucks ass, I've just reduced
|
||||||
|
the polling interval on the ttyplay engine to 100ms, and given
|
||||||
|
up on an otherwise proper select call. Humans shouldn't notice
|
||||||
|
the latency, but I always will... grrr...
|
||||||
|
|
||||||
|
1.2.17 (2003/08/14)
|
||||||
|
* Put in the 50ms delay from header read until payload read during
|
||||||
|
preads in order to hopefully hack/wait around the race condition
|
||||||
|
99% of the time.
|
||||||
|
* Added a sleep(10) after receiving SIGHUP until sending one
|
||||||
|
to the child process in the mild hopes that this gets around
|
||||||
|
whatever condition is causing it not to receive and handle
|
||||||
|
the SIGHUP now.
|
||||||
|
|
||||||
|
1.2.16 (2003/08/14)
|
||||||
|
* All code is now run through indent(1) for cleanliness
|
||||||
|
* Game playback in progress now finds the last term reset and plays
|
||||||
|
forward from the last header before that reset.
|
||||||
|
* Some effort has been made to trap SIGHUP better and pass that
|
||||||
|
along to child processes as well. This still needs work for
|
||||||
|
nethack itself, but dgamelaunch is clean so far.
|
||||||
|
|
||||||
|
1.2.6 (2003/08/08)
|
||||||
|
* Viewing games in progress now works pretty well.
|
||||||
|
|
||||||
|
1.2.0beta2 (2003/08/07)
|
||||||
|
* Added initial ttyrec integration, although everything is very
|
||||||
|
broken at this point. Once I learn more about tty libraries than
|
||||||
|
I ever want to know, maybe everything will work again.
|
||||||
|
|
||||||
|
1.1.6 (2003/08/06)
|
||||||
|
* The last few revs included minor bugfixes found in production use,
|
||||||
|
changed some text in the program, and 1.1.6 is some minor packaging
|
||||||
|
changes for the purposes of a release to the public of the source
|
||||||
|
code.
|
||||||
|
|
||||||
|
1.1.1 (2003/08/02)
|
||||||
|
* Introduced virus (vi editor) code, and provided a new option to edit
|
||||||
|
personal nethack rc files.
|
||||||
|
|
||||||
|
1.0.0 (2003/08/01)
|
||||||
|
* Since 0.2.3 has been in production for over a year and a half, it
|
||||||
|
is hereby dubbed 1.0.0.
|
||||||
|
|
||||||
|
0.2.2 (2001/11/11)
|
||||||
|
* added change password feature. also is the way to get password crypt()ed
|
||||||
|
|
||||||
|
0.2.1 (2001/11/11)
|
||||||
|
* moved more of the crucial config into defines
|
||||||
|
* removed the echo of password on login
|
||||||
|
|
||||||
|
0.2.0 (2001/11/11)
|
||||||
|
* added crypt() support for the password file. Now the program first
|
||||||
|
checks for the crypt() password, then the plaintext one for legacy
|
||||||
|
and for ease of admins changing passwords.

In short, there isn't an easy 'make install' option for this, as it
|
||||||
|
runs in a chroot environment and is somewhat specific to a server.
|
||||||
|
|
||||||
|
It should compile on most modern Linux distros, although there are
|
||||||
|
a couple things which do hinder total portability.
|
||||||
|
|
||||||
|
That said, it shouldn't be too hard to figure out most of the defines
|
||||||
|
in dgamelaunch.(c|h), and I'm more than happy to help out with any
|
||||||
|
questions.

BASIC SETUP INSTRUCTIONS
|
||||||
|
===========================
|
||||||
|
|
||||||
|
1) Setup a chroot area, with a bin directory, a var directory, and a
|
||||||
|
'dgldir' directory. You'll also need 'etc' and 'etc/terminfo' for
|
||||||
|
curses.
|
||||||
|
|
||||||
|
2) If using the #define's as an example, setup 'rcfiles', 'ttyrec',
|
||||||
|
and 'inprogress' directories, in the dgldir. Also touch the files
|
||||||
|
'dgl-login' and 'dgl-lock' in the main chroot directory.
|
||||||
|
|
||||||
|
Your directories/files should now look like this:
|
||||||
|
|
||||||
|
/chrootdir/bin/
|
||||||
|
/chrootdir/var/
|
||||||
|
/chrootdir/etc/
|
||||||
|
/chrootdir/etc/terminfo/
|
||||||
|
/chrootdir/dgldir/
|
||||||
|
/chrootdir/dgldir/ttyrec/
|
||||||
|
/chrootdir/dgldir/inprogress/
|
||||||
|
/chrootdir/dgldir/rcfiles/
|
||||||
|
/chrootdir/dgl-login (empty)
|
||||||
|
/chrootdir/dgl-lock (empty)
|
||||||
|
|
||||||
|
They should all be owned by the user you intend to run this as.
|
||||||
|
|
||||||
|
2) In the #define's in dgamelaunch.c and dgamelaunch.h, change the
|
||||||
|
values for those directories, sort of using my own directory setup
|
||||||
|
as an example.
|
||||||
|
|
||||||
|
3) Compile nethack, and basically tell it that /var is its playground,
|
||||||
|
since it will be in the chroot environment. There should be no need
|
||||||
|
for special nethack compilation instructions, but it will need to be
|
||||||
|
installed to the chroot environment. A static compile will ensure that
|
||||||
|
it can run without any libraries, or you can of course place libraries
|
||||||
|
in the environment.
|
||||||
|
|
||||||
|
For security reasons, I'd avoid putting any shells, etc, in this environment
|
||||||
|
though, of course. Just whatever needs to be exec'd, which is namely,
|
||||||
|
nethack.
|
||||||
|
|
||||||
|
4) Be sure to set the user id's in the #define's of dgamelaunch to
|
||||||
|
the owner of the chroot directory, so nethack and dgamelaunch have
|
||||||
|
access to their files. This user needs a lot of write access, but
|
||||||
|
you can leave the executables owned by someone else.
|
||||||
|
|
||||||
|
5) Either setup dgamelaunch as the shell for a single login, in which
|
||||||
|
case it must be suid root (don't worry. It sheds privs right after the
|
||||||
|
immediate chroot), or set it up as an inetd service. I use the following
|
||||||
|
lines for my xinetd.conf.
|
||||||
|
|
||||||
|
service telnet
|
||||||
|
{
|
||||||
|
socket_type = stream
|
||||||
|
protocol = tcp
|
||||||
|
wait = no
|
||||||
|
user = root
|
||||||
|
server = /usr/sbin/in.telnetd
|
||||||
|
server_args = -L /opt/nethack/nethack.dtype.org/dgamelaunch
|
||||||
|
rlimit_cpu = 3600
|
||||||
|
bind = 64.71.163.206
|
||||||
|
}
|
||||||
|
|
||||||
|
6) Populate /chrootdir/etc/terminfo with terminfo files. I think that most
|
||||||
|
modern ncurses will default to terminfo when it is available. Mine seemed
|
||||||
|
to. This also makes it easy to add term types on the fly.
|
||||||
|
|
||||||
|
7) You can test your compilation of dgamelaunch by simply running
|
||||||
|
it as root, just as a shell (with suid) or inetd might do.
