12     (0) NOTICE
13    
14     Please read this file carefully before trying to set up this bot.
15     Also, make SURE that you select your +n (owner) users wisely! They
16     have 100% access to your bot and account! ONLY GIVE THIS POWER TO
17     SOMEONE YOU TRUST COMPLETELY!!
18    
19     (1) WHAT IS EGGDROP?
20    
21     Eggdrop is an IRC bot, written in C. If you don't know what IRC is,
22     this is probably not whatever you're looking for! Eggdrop, being a
23     bot, sits on a channel and takes protective measures: to keep the
24     channel from being taken over (in the few ways that anything CAN),
25     to recognize banished users or sites and reject them, to recognize
26     priveledged users and let them gain ops, etc.
27    
28     One of the more unique features of eggdrop is its "party line",
29 guppy 1.2 accessible via DCC chat, which allows you to talk to other people
30 segfault 1.1 lag-free. Consider it a multi-way DCC chat, or a miniature IRC
31     (complete with channels). You can link up with other bots and
32     expand the party line until it actually becomes something very much
33     like IRC, in fact.
34    
35 guppy 1.2 Eggdrop is always being improved and adjusted because there are bugs
36     to be fixed and features to be added (if the users demand them, and
37     they make actually sense). In fact, it existed for several years
38     as v0.7 - v0.9 before finally going 1.0. This version of eggdrop is
39     part of the 1.3 tree. A valiant effort has been made to chase down
40     and destroy bugs. It is definitely nowhere near as buggy as the ircII
41     client. Crashes should be rare and surprising (but aren't they always?
42     [surprising anyway]).
43 segfault 1.1
44     This README file contains information about how to get eggdrop, how to
45     quickly compile the bot, what you may need to do when upgrading from
46     older versions, a list of frequently asked questions about compiling,
47     how to set up a crontab, some boring legal stuff, info about the mailing
48 guppy 1.2 list (a great place to ask questions, and a good place to report bugs to),
49     some basics about CVS usage and some channels where you might get help
50     with eggdrop.
51 segfault 1.1
52     The preliminary documentation is in "eggdrop.doc" and is intended to be
53 guppy 1.2 read after you have eggdrop compiled and set up.
54 segfault 1.1
55    
56     (2) HOW TO GET EGGDROP
57    
58     Before you can compile eggdrop, you need to have Tcl installed on
59     your system. Most systems should have Tcl on them by now -- you
60     can check by trying the command "tclsh". If it works, you will be
61     given a "%" prompt, and you can type "exit" to exit the program.
62     That means Tcl is on your system. If tclsh doesn't load, then Tcl
63     probably isn't on your system, and you will need to ftp it. The
64     best ftp site is:
65     ftp://ftp.scriptics.com/pub/tcl
66    
67     The best version to use right now is 8.0.4 (as recommended by
68     dw@Undernet), versions like 7.6p2 are still fine to use though.
69    
70     Tcl comes with the Slackware distribution of Linux. HOWEVER, the
71     one that comes on Slackware 3.0 is goofed up and you'll have to
72     re-install it for yourself to get it working.
73    
74 guppy 1.2 Currently, the 1.3 tree of eggdrop is developed at eggheads.org. You can
75     get the latest version of eggdrop from ftp.eggheads.org.
76     Current mirrors are:
77     ftp.de.eggheads.org
78     ftp.fr.eggheads.org
79    
80     You might try www.eggheads.org for help and information.
81    
82     (2a) CVS USAGE
83    
84     You might obtain the *very latest* version of eggdrop that is still
85     under development by using CVS. CVS means 'Concurrent Versions System'
86     and is a tool for developers to always keep source code up to date.
87     Try 'man cvs' on your shell for more information about CVS ;-)
88    
89     This intended only for users that know a fairly bit about eggdrop.
90     Be aware that the versions of eggdrop that you get by CVS are still
91     being developed, and may be buggy. The 1.3 devel team will in *NO WAY*
92     take any responsability for whatever might happen to you or your shell
93     if you use a CVS version of eggdrop.
94    
95     To obtain eggdrop over CVS, do as follows:
96    
97     (1) log into your shell
98     (2) type 'export CVSROOT=:pserver:anonymous@cvs.eggheads.org:/usr/local/cvsroot'
99     (3) hit enter when it asks for a password.
100     (4) in your home dir, type 'cvs checkout eggdrop1.3'
101     (5) in ~/eggdrop1.3, you should have a copy of the latest CVS version of eggdrop.
102    
103     notes:
104    
105     (1) you can 'cvs logout', but you don't need to
106     (2) you dont need to go through this whole process every time; if you want to get
107     a CVS version of eggdrop at a later time, you just 'cd ~/eggdrop1.3' and type
108     'cvs update'
109     (3) if you errors when using 'export', you might be using tclsh as a shell; just
110     'setenv CVSROOT :pserver:anonymous@cvs.eggheads.org:/usr/local/cvsroot' instead
111     of using 'export'.
112    
113    
114 segfault 1.1 (3) QUICK STARTUP
115    
116     #### NOW INCLUDED IN 'INSTALL' - READ IT *AFTER* FINISHING THIS ####
117    
118 guppy 1.2
119 segfault 1.1 (4) UPGRADING
120    
121 guppy 1.2 (4a) FROM A PRE-1.3 VERSION TO 1.3
122    
123     #### BACK UP YOUR USERFILE ####
124 segfault 1.1
125     We can't re-iterate this enough, if you are upgrading, and you have
126     even a slight possibility of downgrading again later you will HAVE
127     to back up your userfile, or you will lose it. 1.3 radically changes a
128     lot of things.
129    
130     There are many major changes between v0.9, v1.0, v1.1 and v1.3 so
131     PAY ATTENTION
132     to this part if you have a v0.9, 1.0 or 1.1 bot already. If you're
133     just starting out, you can skip this section.
134    
135     to 1.3:
136     * If you run sharebots, you will need to upgrade them all at the
137     same time because of the new userfile format. Older bots will
138     be able to link in, but will not get or send a userfile. 1.2's
139     will also tend to refuse to share with another pre1.2.
140     MAKE A NEW CONFIG FILE from the example, there are some radical
141     extras.
142    
143     from 0.9/1.0 to 1.3:
144     * Just redo the whole thing, absolutely everything has changed
145     including the userfile and config file formats.
146     from 1.1/1.2 to 1.3:
147     * You will likely want to redo the config file, as much as
148     changed. BACK UP!! You will need to run
149     'tclsh scripts/weed <userfile> c' to convert your userfile
150     from v3 (1.1/1.2) to v4
151    
152 guppy 1.2 (4b) FROM AN OLDER 1.3 VERSION TO A NEWER ONE
153    
154     If you followed the INSTALL file and did a 'make install' (or 'make
155     install DEST=<path>') after 'make', this will be pretty easy.
156     Just upload the new eggdrop1.3.xx.tar.gz file to the home dir of your
157     shell, gunzip and untar it, and type 'cd ~/eggdrop1.3.xx'. Then,
158     type './configure', 'make', then kill the bot ('.die' on the partyline,
159     or use 'kill' on the shell) and 'make install' to the same directory
160     your bot is currently in. Then, you can just restart your bot.
161    
162    
163 segfault 1.1 (5) FREQUENTLY ASKED QUESTIONS (or "Why doesn't this thing work?")
164    
165     1. WHAT DO I DO IF I GET THE ERROR "USER FILE NOT FOUND"?
166    
167     (1) Run eggdrop with the "-m" option (ie, "eggdrop -m mybot").
168     (2) Go to IRC and send "hello" to your bot (ie, "/msg mybot hello").
169     (3) You will become an owner on your bot. You can leave the bot
170     running (nobody else will become a master if they say "hello"),
171     but in the future, don't use the "-m" option when running the bot.
172    
173     2. MY EGGDROP WON'T RUN; IT JUST SAYS "CAN'T FIND YOUR HOSTNAME!"
174    
175     Your machine is set up strangely, and eggdrop can't figure out its
176     network hostname. You can get around this by setting an environment
177     variable called HOSTNAME. In sh or ksh:
178     $ HOSTNAME=myhost.domain.edu
179     $ export HOSTNAME
180     In csh or tcsh:
181     % setenv HOSTNAME myhost.domain.edu
182     It should work after that. You may want to bug your system admini-
183     strator to set up her /etc/hosts file correctly, or add those above
184     commands to your '.login' file (sh or ksh: '.profile').
185    
186     3. WHAT THE HECK IS TCL?
187    
188     Tcl is a scripting language written by John Ousterhout. It's much
189     better than most "in-built" script langauges (like the one in ircII)
190     and is meant to be linked with anything needing a script language.
191     So I linked it with eggdrop.
192    
193     The file "tcl-commands.doc" in the eggdrop directory contains a list
194     of the commands added to Tcl by eggdrop. There are also several
195     example scripts in the scripts/ directory, and there are gobs of
196     scripts floating around on the ftp sites if you like working by
197     example (which is typically the best way).
198    
199     4. MY BOT DIES AND THE LAST ENTRY IN THE LOGFILE IS "RECEIVED TERMINATE
200     SIGNAL". WHAT DOES THAT MEAN AND CAN I PREVENT IT?
201    
202     There's nothing you can do to prevent it. It means the system admini-
203     stator is killing the eggdrop process. Most of the time, it's an
204     automatic thing that happens when the system is being rebooted -- so
205     it's harmless, and if you have a crontab running, the bot will get
206     restarted when the system is back online. Occassionally the system
207     administrator will kill the bot manually -- for example, if he/she
208     doesn't want bots running on the system.
209    
210     5. MY COMPILE DIES AT THE LAST MINUTE WITH "LD FATAL SIGNAL 11"!
211    
212     This happens on Linux machines which have recently been converted
213     to ELF by upgrading to Slackware 3.0. Apparently Slackware 3.0
214     comes with a non-ELF (a.out) Tcl library, and the compiler doesn't
215     handle that well. (It should give you an error; instead it barfs.)
216     Fixing it is tricky because even if you recompile libtcl.a, the
217     linker will most likely find the "bad" one first, and your work
218     will be in vain.
219    
220     Here's a fix that's been floating around on the eggdrop list:
221     1. Recompile 'libtcl.a' for yourself, to make sure an ELF library
222     is created.
223     2. Copy it into your eggdrop/src directory, naming it 'libtcl2.a'.
224     3. Edit the Makefile and change the line that says '-L/usr/lib -ltcl'
225     to '-L. -ltcl2'.
226     4. Recompile eggdrop.
227    
228     Also send hate-mail to the Slackware guy telling him to stop messing
229     up the libraries. He seemed to assume that everyone would still
230     want to compile old-style (a.out) binaries.
231    
232     6. SOMEONE ELSE SET UP A BOT I DON'T LIKE. ARE THERE ANY BACKDOORS I
233     CAN USE TO TAKE THEIR BOT DOWN?
234    
235     No, there have never been any backdoors and there never will be,
236     so please stop asking. Every once in a while, someone finds a way
237     to exploit a bug in eggdrop, but we fix these bugs as soon as I find
238     out about them. If you want to bring down someone else's bot, you
239     will not have my/our help.
240    
241     6. WHAT ARE MODULES?
242    
243     Modules are a way of adding extra C code from the bot, much
244     like tcl scripts, without requiring the bot recompiling, see
245     doc/MODULES for more info.
246    
247     7. CAN I COMPILE EGGDROP WITHOUT DYNAMIC MODULES?
248    
249     Yes, you can, if ./configure detects that your system CAN'T run
250     modules it will setup 'make' to link the modules in statically
251     for you, you can also choose this option if you can do dynamic
252     modules by typing 'make static'. You can also try to compile
253     dynamic modules on a static-only system by typing 'make eggdrop'.
254    
255     7.1 DO I STILL NEED TO 'loadmodule modules' ???
256    
257     YES, when you compile statically, all the modules are linked into
258     the main executable *but* they are not enabled until you use
259     loadmodule to enable then, hence you get nearly the same
260     functionality with static modules as dynamic modules.
261    
262     8. WHERE CAN I GET A PRECOMPILED EGGDROP FOR MY COMPUTER?
263    
264     It is HIGHLY recommended AGAINST using precompiled Eggdrops
265     from untrusted sources. Eggdrop has been a regular target
266     for hacking and crashing. Distribution of precompiled (binary)
267     versions of Eggdrop are the easiest way of hackers to provide
268     you with the easiest (and most dangerous) way of gaining access
269     to not only your bot, but to your computer account directly.
270     Don't advertise your precompiled eggdrop binary sites on the
271     eggdrop list either =P
272    
273     9. I GET 'Makefile:3 :invalid operator' OR SOME-SUCH-THING
274     WHEN I TRY TO 'make'
275    
276     Try 'gmake'
277    
278     10. WHEN I 'tclsh scripts/weed <userfile> c' IT BARFS CHUNKS AT ME
279     AND DIES :(
280    
281     UPGRADE YOUR TCL, you are probably using tcl 7.5 or earlier,
282     some of the commands in weed require tcl7.6 to run, so either
283     upgrade it, or removing the offending lines from you
284     userfile (those strating with '.' generally) and accept the
285     loss of that data.
286    
287     11. I get "ld-elf.so.1: Shared object "libtcl80.so.1" not found" or
288     "eggdrop: error in loading shared libraries /
289     libtcl8.1.so: cannot open shared object file: No such file or directory"
290     when I try to start my bot.
291    
292     './configure' is looking in the wrong place for tcl; it looks like
293     it compiled with one version of tcl and tries to load another.
294     Maybe your sysadmin upgraded tcl and didnt tell you.
295     In that case, you should just need to recompile your bot.
296    
297     Or maybe when upgrading he didnt clean the old version of tcl, and
298     './configure' is looking for the files in the wrong places, or
299     trying to use different versions of tcl.h and libtcl*.
300     Smack your admin and have him install tcl properly ;)
301     Or try to:
302    
303     ./configure --with-tcllib=<path-to-tcllib> --with-tclinc=<path-to-tclinc>
304    
305     tell configure where to look for the tcl files.
306     try to look for them like:
307     for libtcl: ls /usr/lib/libtcl*
308     ls /usr/local/lib/libtcl*
309     for tcl.h: ls /usr/include/tcl.h
310     ls /usr/local/include/tcl.h
311    
312     If everything else fails, try to install tcl to your home dir ;)
313     (suggested by dw@Undernet, dw@lixom.nu)
314    
315    
316     12. I get a whole pile of "Unresolved symbol 'Tcl_AppendResult'"
317     (or some other symbol) when I try to load a modules.
318    
319     POSSIBILITY A: see 11.
320    
321     POSSIBILITY B:
322    
323     Some of the standard libraries have been compiled for static
324     linking only on your machine, you have 3 options:
325     (1) if it's your own machine, recompile TCL using dynamic linking
326     by using './configure --enable-shared' when you configure
327     TCL (not the bot) and then remake, & reinstall
328     (2) if it's not you machine, you make have to resort to
329     'make static' and 'make sinstall DESTDIR=<dir>' to make
330     and install your bot.
331     (3) if you are of a more aggressive sense of mind, go beat the
332     stuffing out of your admin for have lame static libraries :)
333    
334     (6) SETTING UP A CRONTAB
335    
336     Eggdrop has become more stable with time, thanks mostly to people detail-
337     ing bugs to me and helping me find places where it crashes. However, I'm
338     sure there are still a few places where things aren't perfect -- that's
339     how life works. Also, most systems go down from time to time. These
340     things cause your bot to disappear from IRC, and you have to restart it.
341    
342     I have included a csh script called 'botchk' which will help keep the bot
343     online. It will make the machine check every ten minutes to make sure
344     your bot is still running. To use it, you have to add a line to your
345     crontab. First, edit 'botchk' and change the directory and command line
346     parameters so that it will be able to start up your bot. Then, add this
347     line to your crontab:
348    
349     0,10,20,30,40,50 * * * * /home/mydir/botchk
350    
351     If you don't want to get emails from cron, put this:
352    
353     0,10,20,30,40,50 * * * * /home/mydir/botchk >/dev/null 2>&1
354    
355     Naturally, you need to change the path to the correct path for botchk. If
356     you've never used crontab before, here is a simple way to add that line:
357     Create a new file called 'mycron' and put the above line into it. Then,
358     from your shell prompt, type
359     % crontab mycron
360     That will create a new crontab entry for you, with a line that runs botchk
361     every ten minutes. Botchk will then restart the bot when necessary (and
362     send you email informing you).
363    
364    
365     (7) BORING LEGAL STUFF
366    
367     The eggdrop bot is copyright (c) by Robey Pointer. As of January 1997,
368     eggdrop is distributed according to the GNU General Public License.
369     There should be a copy of this license in the file COPYING. If not,
370     write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge,
371     MA 02139, USA.
372    
373     Releases previous to 1.0m were made using a different licensing scheme.
374     You may, at your option, use the GNU General Public License on those
375     versions (instead of the license packaged with them) with my blessing.
376     For any versions bearing a copyright date of 1997 or later, you have
377     no choice -- you must use the GNU General Public License.
378    
379     The files "match.c", "net.c", and "blowfish.c" are exempt from the above
380     restrictions. "match.c" is original code by Chris Fuller (email:
381     crf@cfox.bchs.uh.edu) and has been placed by him into the public domain.
382     "net.c" is by me and I also choose to place it in the public domain.
383     "blowfish.c" is by various sources and is in the public domain. All 3
384     files contain useful functions that could easily be ported to other
385     applications -- the other parts of the bot generally don't.
386    
387     Tcl is by John Ousterhout and is in no way affiliated with eggdrop,
388     and has its own set of copyrights and whatnots, I'm sure.
389    
390     There is no warranty, implied or whatever. You use this software at
391     your own risk, no matter what purpose you put it to.
392    
393     You didn't pay for it, so don't expect magic.
394    
395    
396     (8) MAILING LIST
397    
398 guppy 1.2 There are currently a couple of mailing lists about eggdrop.
399     eggheads@eggdheads.org is the one relevant for posts about
400     eggdrop 1.3 (and bug fixes, and suggestions, etc).
401    
402     To subscribe to the eggheads mailing list, send email to:
403     eggheads-request@eggheads.org
404     In the body of the message, put "subscribe eggheads"; or go to
405     http://scrambled.eggheads.org/mailman/listinfo/eggheads
406 segfault 1.1
407     ### DO NOT SEND ROBEY EMAIL ABOUT EGGDROP ###
408     Robey is no longer developing the eggdrop code (although he does put
409     a word in every now and then) so don't bother emailing him. If you
410     have a serious problem, email the eggdrop mailing list and it will
411     get to the coders.
412    
413     Please, before posting to this list, see what things are like, and
414     when you do post, read over your post for readability, spelling, and
415     grammar mistakes. Obviously, we're all human (or are we?) and we all
416     make mistakes (heck, look at this document! ;). Don't flame, and
417     read/follow the rules.
418    
419 guppy 1.2 This list is not, and never will be a list dedicated to those all too
420     common questions we have all seen on other lists... for example:
421    
422     "Why does my bot say this: Please edit your config file."
423     "How do I telnet my bot?"
424     "Where do I get eggdrop for windows????????"
425     etc..
426

440     (10) OBTAINING HELP
441    
442 guppy 1.2 There is currently no uniform channel in existance to support eggdrop.
443     At one time, such channels did exist, but they most often esculate into
444     a vanity channel, where no one is willing to help.
445    
446     However, we'll list a few places here where you *might* get help. Note
447     though that we are not responsible for those channels, or neccessarily
448     run those channels ourselves.
