Added signal handlers to the NullLoop. Added xterm, screen and ansi to the acceptable TERM types. *usage.c: Added info for -l switch. * README: Updated usage info for the -l switch. Added notes about the -l switch. Updated beta testers list. 2003-01-31 Joe Laffey * spinner.c: Fixed signal handling that prevented termination on logout. 2003-01-30 Joe Laffey * README: Added beta testers. * AUTHORS: Added beta testers. * spinner.h: Included for pid_t typedef. (bug reported by Michael Hostbaek ). * spinner.c: Called tcdrain() on TTY in NullLoop(). 2003-01-29 Joe Laffey * README: Added usage info for the -n switch. Typo/grammar fixes. * usage.c: Added usage info for the -n switch. * spinner.c: Minor code cleanup (var names). 2003-01-28 Joe Laffey * automake.am: Added autoconf/automake support * spinner.c: cleaned up code. Better signal handling support for -n switch to only send null charcters. Moved usage/license into usage.c. Broke header out into spinner.h and usage.h. Added checks for setuid and setgid modes. Added timeout to opening the tty. Positively terminate strings. Pull HOME from /etc/passwd instead of the env var. Removed writing pid file to current dir. Terminal is now drained before and after each write. spinner-1.2.4/configure0000755000076500001430000035033007624271567010610 #! /bin/sh # Guess values for system-dependent variables and create Makefiles. # Generated by GNU Autoconf 2.57. # # Copyright 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This configure script is free software; the Free Software Foundation # gives unlimited permission to copy, distribute and modify it. ## --------------------- ## ## M4sh Initialization. ## ## --------------------- ## # Be Bourne compatible if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then emulate sh NULLCMD=: # Zsh 3.x and 4.x performs word splitting on ${1+"$@"}, which # is contrary to our usage.

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 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. Copyright (C) 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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. , 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 Library General Public License instead of this License. spinner-1.2.4/depcomp0000755000076500001430000002753307576772404010266 #! /bin/sh # depcomp - compile a program generating dependencies as side-effects # Copyright 1999, 2000 Free Software Foundation, Inc. # 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, 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.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the `--target=TYPE' option to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc will cause the specified gcc to be used as the C compiler (unless it is overridden in the site shell script). `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. spinner-1.2.4/install-sh0000755000076500001430000001425307576772403010707 #!/bin/sh # # install - install a program, script, or datafile # This comes from X11R5 (mit/util/scripts/install.sh). # # Copyright 1991 by the Massachusetts Institute of Technology # # 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, and that the name of M.I.T. not be used in advertising or # publicity pertaining to distribution of the software without specific, # written prior permission.

To make this effect it cycles through punctuation marks like this " - \ | / - \ | / ... " (try it to see). By default the character is drawn in inverse video (or your terminal's equivalent). But you can turn this off with the -i switch. In spinner mode Spinner supports any terminal capable of handling VT100 style escape codes. In null mode (-n switch) Spinner supports any terminal. In null mode there is no visible output, and Spinner will not interfere with your terminal or scrollback. If you find the little spinner in the top left corner to be distracting use null mode. (-n switch). Spinner is useful for keeping telnet and ssh links from dropping due to inactivity. Many firewalls, and some ISPs drop connections when they are perceived as idle. By having spinner running the server is constantly sending a tiny amount of data over the link, preserving the connection. As of version 1.2 Spinner can also be activated with the -n switch so that, instead of displaying a spinner, it simply sends out a periodic null character to the terminal. This achieves the same anti-idle benefit without disturbing your screen. But it lacks the coolness factor of a little spinner in the corner of the terminal... Thus (for search engines) Spinner is an anti-idle, timeout preventing, background daemon process for unix variants including linux. Spinner is known to compile and work properly under NetBSD 1.5 and 1.6, Mac OS X 10.2, linux 2.2 and 2.4. Spinner also has a (mainly fun) mode I like to call "Ghost in the Machine" mode. In this mode you can use spinner to write the spinner character to ANY tty, not just your own. This requires adequate permissions, of course. (see below) ----------------- HOW DO I USE IT? ----------------- Basic summary: (spinner -h) Usage: spinner[-IntTuvl[f|F][p|P]] [delay] -f Set pid file path (default is ~/.spinner.pid) -F Do *not* create a pid file -I Do *not* use inverse video for spinner -l Set log file path (for debugging). Off by default. -L Display the license -n Send only null characters. (No visible output.) -p Specify process priority to use -P Do *not* change process priority (default is to make nice) -r Reset term on quit (Use if you get left in inverse a lot.) -R Reset the term and Quit immediately. (nothing else) -t Specify path of TTY to which to write -T Ignore incompatible TERM environment var setting -u Delay is in microseconds instead of seconds -v Verbose mode (lots of output) Returns: 0 on success, non-zero on failure. Launches into the background on success. Use: kill `cat ` to stop. ---------------- IMPORTANT INFO <--read this ---------------- * IN ORDER FOR SPINNER TO PREVENT IDLE CONNECTIONS YOU MUST RUN IT ON THE SERVER. If you run Spinner on your client the data is not sent over the wire. It is only drawn locally. So you must run Spinner on the remote machine to keep the data coming to your terminal over the wire. If you do not have root access on the remote machine you can still use Spinner. Compile Spinner with "./configure --prefix= && make install". You can then launch Spinner from your .login file or .tcshrc / .profile file if you wish. * Spinner is a daemon process (also known as a background process). When you start spinner it will launch into the background as not to interfere much with your foreground jobs. By default Spinner creates a pid (process id) file called ".spinner.pid" in your home directory. (You may use the -f or -F switches to modify this behavior.) Note this pid file has a "." character in front so you will need to use ls -a to see it in a listing. You can use this file to easily kill Spinner with the command: kill `cat ~/.spinner.pid` Note that those are backticks (top left key below ESC, same key with ~). Of course you can also just find Spinner in your process list and kill it manually that way. Spinner's pid file is NOT a lock file. It will be overwritten every time you launch a copy of Spinner. So if you have multiple spinners running you will have to kill them manually. Spinner should commit suicide (i.e. quit) if the tty to which it is writing is no longer active. Sometimes, if you start Spinner writing to another tty when that tty is not active to begin with Spinner will not quit. (Anyone know why?? Tell me.) * Since Spinner draws to the terminal it is possible (and likely) that the spinner character will end up in the terminal's scrollback. To reduce this annoyance you can use a long delay. As of version 1.2 you may opt to use the -n switch to cause spinner to send only null characters, instead of the spinning cursor. If you do not use -n you may also kill Spinner with the STOP signal (kill -STOP `cat ~/.spinner.pid`) and then continue it after you get your scrollback via the CONT signal (kill -CONT `cat ~/.spinner.pid`). * Spinner may interfere with the display of mouse selections. If you drag out a selection the highlighted text may become unhighlighted as sooner as Spinner draws to the terminal. Typically the contents of the paste buffer still remain, however. So even though you lose the highlighting you can still paste the text that you selected in the usual fashion. Again, as of version 1.2 you may opt to use the -n switch to cause Spinner to only send null characters to the screen (which do not show up). * At startup spinner checks to be sure your TERM environment variable is set to "vt100" or "vt102". It only checks for these since these are the only terminal types that I KNOW will accept the vt100 escape codes (to move the cursor, inverse video, etc.) Spinner works perfectly well in every terminal I have tried it in (including GNU screen, eterm, xterm, aterm, etc.) If you get the message about your terminal not being "vt100" or "vt102" simply invoke Spinner with the -T switch. This forces Spinner to ignore the TERM setting. Note that if you use spinner on a dumb terminal, or any other terminal that does not support the escape codes you will see a lot garbage characters. Just stop Spinner and get a real terminal! If you find this check annoying, or think it should go away let me know. Note that if you use the -n switch Spinner will not check the terminal type at all, as it is not attempting to move the cursor, change inverse modes, etc. * Note that if you would like to use Spinner in conjunction with the GNU screen program (one of the world's coolest programs, screen is a "terminal multiplexer" allowing multiple virtual terminals in a single terminal window, switching between them, detaching and resuming screens both local and remote, etc.) you will want to start Spinner *BEFORE* you start screen. Otherwise Spinner will end up in one of screen's virtual terminals, which means that it may not be on the real terminal all the time. This could lead to an idle timeout, which is exactly what Spinner was coded to prevent. You may also be able to determine your parent tty (the original tty from which you invoked screen), and have Spinner write to that tty using the -t switch. (This would let you invoke Spinner in such a way that it would write to the parent terminal even though you launched Spinner from within screen. * In normal operation (delay >= 2 sec) Spinner functions well with most terminals / emulators. However, if you switch to microsecond mode for the delay (-u) and use lower delays it is possible that your terminal will become somewhat garbled. You will notice that parts of the screen that shouldn't be are displayed in inverse text, or text is in the wrong place, etc. Setting a higher delay will normally make this issue non-existent. Note that "Terminal.app" under Mac OSX seems more prone to do this. Gnome term and eterm, etc seem immune. **NOTE: In version 1.2 the code was reworked to all but eliminate this. If you encounter this issue, please send me an email with your system info. Since when using the -n switch Spinner does not send printable characters you will not experience this problem at all. * If you use an extremely low delay on a slow link, or use a slow-drawing terminal, be prepared for Spinner to slow your terminal down. I would say, "Don't do that!" Spinner is coded to be very efficient in its main loop. Only one write statement and one check to be sure the tty is active per iteration. Since Spinner is meant as an anti-idle tool you will most likely keep the delay high (but less than 30 sec or so depending upon what it is that is timing out your connection to begin with). * By default Spinner will set its process priority (niceness) to 10. You can use the -p or -P switches to modify this behavior. * Sometimes when you terminate Spinner it could leave the terminal in a state you were not expecting (e.g. inverse video "stuck" on, cursor in the wrong spot, etc.) If you experience this a lot consider the -r switch. This will send a vt100 reset code at quit, which usually helps, but will clear your terminal screen. **NOTE: In version 1.2 the code was reworked to all but eliminate this. If you encounter this issue, please send me an email with your system info. If your terminal gets stuck in an inconsistent (read "whacked") state you can try to fix it by running Spinner with the -R switch. With this switch ALL Spinner will do is sen a vt100 reset code to the tty (then quit). Using the -n switch will avoid these problem altogether by sending only null characters to the terminal. You loose the cool little spinner effect, however. * Verbose mode will walk you through most of the steps Spinner takes as it launches. Mainly for debugging, it can, however, help you troubleshoot switch settings. Note that once Spinner has forked to the background it no longer has a controlling terminal and cannot output error messages. In or to see verbose output (or errors) after the fork you must use the -l switch and specify a filename to write to. This file will ONLY contain the output from Spinner AFTER the fork. Most likely you will never need this, but it is available if you do. Note that it t is perfectly normal to see a no such file or directory error in this log when logging out of linux. Linux cretaes and deletes files in /dev/pts/ with every change of TTY. * Ghost in the Machine mode (i.e. using the -t switch to write to another tty other than your controlling terminal) can be both fun and (a little) useful. To use this mode determine the PATH to the tty you want Spinner to write. Usually the "tty" command will display your own terminal. This should give you the basic path/filename structure (usually "/dev/ttypXX" where "XX" is a number). Then do a "who" command to see which particular tty you want to write to. This will show you a list of logged in users and their ttys. Next run spinner with the -t switch and specify the path to the desired tty. Note that you must have permission to write to the desired tty. Ttys are setup to be owned by the user logged into them, and usually setup with a group of "tty". So you can always write to any of your own ttys. To write to someone else's tty you either need to be root, or root needs to setup Spinner as setgid (not setuid) "tty". There are security concerns with any setuid or setgid program. So don't be surprised if your administrator says no. Spinner has not been thoroughly audited for security. Though little could go wrong, small seemingly meaningless things can lead to real big security holes. You've been warned. Spinner is NOT installed setgid (or setuid) by using the "make install" command. Spinner will not run if it is made setuid. ------------- TO DO ------------- Allowing the user to specify the position of the spinning character might be fun, and somewhat useful. Perhaps putting the spinner into a banner at the top or bottom of the screen (like GNU screen's dividers) would be useful, as they spinner would not encroach into the active terminal area (the virtual terminal would be made smaller) Adding a spinner to the existing banner in the GNU screen program would be very useful for those who use screen. Calls to signal() should be replaced with sigaction() stuff. Any way to prevent scrollback of the spinner character instead of valid data would be useful (such as the banner at the bottom previously mentioned). Perhaps a switch to kill running Spinner(s) instead of using the kill command might be useful for novice users. However, novice users are unlikely to be using Spinner to begin with... ------------------------------- Who Made This Thing? (and Why?) ------------------------------- Original code: Joe Laffey I made it to keep alive ssh connections that were being timed out by my firewalls. Plus it looks cool, and was a nice experiment in writing directly to ttys.
