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.

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 \fIxauth\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 \fIxauth\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 \fIxauth\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, +\fIxauth\fP will use the file specified by the XAUTHORITY environment variable +or \fI\.Xauthority\fP in the user's home directory. +.TP 8 +.B \-q +This option indicates that \fIxauth\fP should operate quietly and not print +unsolicited status messages. This is the default if an \fIxauth\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 \fIxauth\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 \fIxauth\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 \fIxauth\fP should ignore any authority file +locks. Normally, \fIxauth\fP will refuse to read or edit any authority files +that have been locked by other programs (usually \fIxdm\fP or another +\fIxauth\fP). +.TP 8 +.B \-b +This option indicates that \fIxauth\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 \fIxauth\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 \fIxauth\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 \fIxauth\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 + % xauth extract \- $DISPLAY | rsh otherhost xauth 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 + % xauth generate :0 . +.fi +.SH ENVIRONMENT +This \fIxauth\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 new file mode 100644 index 000000000..104eb1ebc --- /dev/null +++ b/nx-X11/programs/nxauth/parsedpy.c @@ -0,0 +1,259 @@ +/* + * $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.
