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 Lesser 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 - - 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) <year> <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., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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. - - <signature of Ty Coon>, 1 April 1989 - Ty Coon, President of Vice - -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 Lesser General -Public License instead of this License. diff --git a/nx-X11/programs/nxauth/Imakefile b/nx-X11/programs/nxauth/Imakefile deleted file mode 100644 index 278904f05..000000000 --- a/nx-X11/programs/nxauth/Imakefile +++ /dev/null @@ -1,38 +0,0 @@ -XCOMM $Xorg: Imakefile,v 1.3 2000/08/17 19:54:11 cpqbld Exp $ - - - - -XCOMM $XFree86: xc/programs/xauth/Imakefile,v 3.5 2001/03/30 02:15:23 keithp Exp $ - -/**************************************************************************/ -/* */ -/* Copyright (c) 2001, 2010 NoMachine, http://www.nomachine.com/. */ -/* */ -/* NXAUTH, NX protocol compression and NX extensions to this software */ -/* are copyright of NoMachine.

This program is usually -used to extract authorization records from one machine and merge them in on -another (as is the case when using remote logins or granting access to -other users). Commands (described below) may be entered interactively, -on the \fInxauth\fP command line, or in scripts. Note that this program -does \fBnot\fP contact the X server except when the generate command is used. -Normally \fInxauth\fP is not used to create the authority file entry in -the first place; \fIxdm\fP does that. -.SH OPTIONS -The following options may be used with \fInxauth\fP. They may be given -individually (e.g., \fI\-q \-i\|\fP) or may combined (e.g., \fI\-qi\|\fP). -.TP 8 -.B "\-f \fIauthfile\fP" -This option specifies the name of the authority file to use. By default, -\fInxauth\fP will use the file specified by the nxauthORITY environment variable -or \fI\.Xauthority\fP in the user's home directory. -.TP 8 -.B \-q -This option indicates that \fInxauth\fP should operate quietly and not print -unsolicited status messages. This is the default if an \fInxauth\fP command is -is given on the command line or if the standard output is not directed to a -terminal. -.TP 8 -.B \-v -This option indicates that \fInxauth\fP should operate verbosely and print -status messages indicating the results of various operations (e.g., how many -records have been read in or written out). This is the default if \fInxauth\fP -is reading commands from its standard input and its standard output is -directed to a terminal. -.TP 8 -.B \-i -This option indicates that \fInxauth\fP should ignore any authority file -locks. Normally, \fInxauth\fP will refuse to read or edit any authority files -that have been locked by other programs (usually \fIxdm\fP or another -\fInxauth\fP). -.TP 8 -.B \-b -This option indicates that \fInxauth\fP should attempt to break any authority -file locks before proceeding. Use this option only to clean up stale locks. -.SH COMMANDS -The following commands may be used to manipulate authority files: -.TP 8 -.B "add \fIdisplayname protocolname hexkey" -An authorization entry for the indicated display using the given protocol -and key data is added to the authorization file. The data is specified as -an even-lengthed string of hexadecimal digits, each pair representing -one octet. The first digit of each pair gives the most significant 4 bits -of the octet, and the second digit of the pair gives the least significant 4 -bits. For example, a 32 character hexkey would represent a 128-bit value. -A protocol name consisting of just a -single period is treated as an abbreviation for \fIMIT-MAGIC-COOKIE-1\fP. - -.TP 8 -.B "generate \fIdisplayname protocolname\fP \fR[\fPtrusted|untrusted\fR]\fP" -.B \fR[\fPtimeout \fIseconds\fP\fR]\fP \fR[\fPgroup \fIgroup-id\fP\fR]\fP \fR[\fBdata \fIhexdata\fR] - -This command is similar to add. The main difference is that instead -of requiring the user to supply the key data, it connects to the -server specified in \fIdisplayname\fP and uses the SECURITY extension -in order to get the key data to store in the authorization file. If -the server cannot be contacted or if it does not support the SECURITY -extension, the command fails. Otherwise, an authorization entry for -the indicated display using the given protocol is added to the -authorization file. A protocol name consisting of just a single -period is treated as an abbreviation for \fIMIT-MAGIC-COOKIE-1\fP. - -If the \fBtrusted\fP option is used, clients that connect using this -authorization will have full run of the display, as usual. If -\fBuntrusted\fP is used, clients that connect using this authorization -will be considered untrusted and prevented from stealing or tampering -with data belonging to trusted clients. See the SECURITY extension -specification for full details on the restrictions imposed on -untrusted clients. The default is \fBuntrusted\fP. - -The \fBtimeout\fP option specifies how long in seconds this -authorization will be valid. If the authorization remains unused (no -clients are connected with it) for longer than this time period, the -server purges the authorization, and future attempts to connect using -it will fail. Note that the purging done by the server does \fBnot\fP -delete the authorization entry from the authorization file. The -default timeout is 60 seconds. - -The \fBgroup\fP option specifies the application group that clients -connecting with this authorization should belong to. See the -application group extension specification for more details. The -default is to not belong to an application group. - -The \fBdata\fP option specifies data that the server should use to -generate the authorization. Note that this is \fBnot\fP the same data -that gets written to the authorization file. The interpretation of -this data depends on the authorization protocol. The \fIhexdata\fP is -in the same format as the \fIhexkey\fP described in the add command. -The default is to send no data. - -.TP 8 -.B "[n]extract \fIfilename displayname..." -Authorization entries for each of the specified displays are written to the -indicated file. If the \fInextract\fP command is used, the entries are written -in a numeric format suitable for non-binary transmission (such as secure -electronic mail). The extracted entries can be read back in using the -\fImerge\fP and \fInmerge\fP commands. If the filename consists of -just a single dash, the entries will be written to the standard output. -.TP 8 -.B "[n]list \fR[\fIdisplayname\fP...]" -Authorization entries for each of the specified displays (or all if no -displays are named) are printed on the standard output. If the \fInlist\fP -command is used, entries will be shown in the numeric format used by -the \fInextract\fP command; otherwise, they are shown in a textual format. -Key data is always displayed in the hexadecimal format given in the -description of the \fIadd\fP command. -.TP 8 -.B "[n]merge \fR[\fIfilename\fP...]" -Authorization entries are read from the specified files and are merged into -the authorization database, superceding any matching existing entries. If -the \fInmerge\fP command is used, the numeric format given in the description -of the \fIextract\fP command is used. If a filename consists of just a single -dash, the standard input will be read if it hasn't been read before. -.TP 8 -.B "remove \fIdisplayname\fR..." -Authorization entries matching the specified displays are removed from the -authority file. -.TP 8 -.B "source \fIfilename" -The specified file is treated as a script containing \fInxauth\fP commands -to execute. Blank lines and lines beginning with a sharp sign (#) are -ignored. A single dash may be used to indicate the standard input, if it -hasn't already been read. -.TP 8 -.B "info" -Information describing the authorization file, whether or not any changes -have been made, and from where \fInxauth\fP commands are being read -is printed on the standard output. -.TP 8 -.B "exit" -If any modifications have been made, the authority file is written out (if -allowed), and the program exits. An end of file is treated as an implicit -\fIexit\fP command. -.TP 8 -.B "quit" -The program exits, ignoring any modifications. This may also be accomplished -by pressing the interrupt character. -.TP 8 -.B "help [\fIstring\fP]" -A description of all commands that begin with the given string (or all -commands if no string is given) is printed on the standard output. -.TP 8 -.B "?" -A short list of the valid commands is printed on the standard output. -.SH "DISPLAY NAMES" -Display names for the \fIadd\fP, \fI[n]extract\fP, \fI[n]list\fP, -\fI[n]merge\fP, and \fIremove\fP commands use the same format as the -DISPLAY environment variable and the common \fI\-display\fP command line -argument. Display-specific information (such as the screen number) -is unnecessary and will be ignored. -Same-machine connections (such as local-host sockets, -shared memory, and the Internet Protocol hostname \fIlocalhost\fP) are -referred to as \fIhostname\fP/unix:\fIdisplaynumber\fP so that -local entries for different machines may be stored in one authority file. -.SH EXAMPLE -.PP -The most common use for \fInxauth\fP is to extract the entry for the -current display, copy it to another machine, and merge it into the -user's authority file on the remote machine: -.sp -.nf - % nxauth extract \- $DISPLAY | rsh otherhost nxauth merge \- -.fi -.PP -.sp -The following command contacts the server :0 to create an -authorization using the MIT-MAGIC-COOKIE-1 protocol. Clients that -connect with this authorization will be untrusted. -.nf - % nxauth generate :0 . -.fi -.SH ENVIRONMENT -This \fInxauth\fP program uses the following environment variables: -.TP 8 -.B XAUTHORITY -to get the name of the authority file to use if the \fI\-f\fP option isn't -used. -.TP 8 -.B HOME -to get the user's home directory if XAUTHORITY isn't defined. -.SH FILES -.TP 8 -.I $HOME/.Xauthority -default authority file if XAUTHORITY isn't defined. -.SH BUGS -.PP -Users that have unsecure networks should take care to use encrypted -file transfer mechanisms to copy authorization entries between machines. -Similarly, the \fIMIT-MAGIC-COOKIE-1\fP protocol is not very useful in -unsecure environments. Sites that are interested in additional security -may need to use encrypted authorization mechanisms such as Kerberos. -.PP -Spaces are currently not allowed in the protocol name. Quoting could be -added for the truly perverse. -.SH AUTHOR -Jim Fulton, MIT X Consortium diff --git a/nx-X11/programs/nxauth/parsedpy.c b/nx-X11/programs/nxauth/parsedpy.c deleted file mode 100644 index d0f022574..000000000 --- a/nx-X11/programs/nxauth/parsedpy.c +++ /dev/null @@ -1,259 +0,0 @@ -/* - * $Xorg: parsedpy.c,v 1.4 2001/02/09 02:05:38 xorgcvs Exp $ - * - * parse_displayname - utility routine for splitting up display name strings - * - * -Copyright 1989, 1998 The Open Group - -Permission to use, copy, modify, distribute, and sell this software and its -documentation for any purpose is hereby granted without fee, provided that -the above copyright notice appear in all copies and that both that -copyright notice and this permission notice appear in supporting -documentation. - -The above copyright notice and this permission notice shall be included in -all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
