Re: Need help building php4

I've never done this before, and reading the directions is leaving me with a few questions. First, am I getting the right files? I typed apt-get source php4 and then found the files in /etc/apt. The instructions said to run configure in the php4 source directory which I did (to compile the dynamic module). When this is done, the script says that it's the CGI version ... I don't think this is what I want ... What I want is to be able to use mod_php4, like what I have currently (except that the current install has a few issues, hence the recompile: e.g. it says that squirrel mail is redefining functions when it's not). as with any autoconf-generated configure script, you can always run ./configure --help to get a list of all available configure options. Among these, you'll find --with-apxs and --prefix, etc. and a whole bunch of --with-* or --enable-* options, some of which might apply here. To build the dynamically loadable apache module (DSO), you probably need at least something like ./configure --with-apxs (or ./configure --with-apxs=/usr/bin/apxs, if apxs should not be found for some reason) plus some other --with-* options (e.g. --with-mysql). Also, the --prefix[=DIR] option might come in handy to get make install to put the stuff in the right directories. For the purpose at hand, though, it might suffice to manually copy the libphp4.so file to /usr/lib/apache/1.3/, the rest should already have been setup correctly upon installation of the original php4 deb-package. The INSTALL document that comes with php includes some more details, in particular the section VERBOSE INSTALL, subsections 2a and 4a. You probably also need to get the apache-dev package, as this includes the apxs tool. Along similar lines, always check whether there is some developer package, in case you find something is missing when trying to build things from sources (this might happen for some of the other --with-* options...). As usual, http://packages.debain.org/ is your friend, if you need to locate which package a specific file is contained in. Also see http://packages.debian.org/testing/web/php4.html for the list of php add-on modules that are built into the regular deb-package. If you need the associated funtionalities, you might (or might not) need to specify the appropriate --with-* or --enable-* option to configure, depending on the defaults in effect (see the output of --help). I'm not a PHP expert (personally prefer mod_perl), so I can't tell you any details on which options you most probably want, and how to get those working properly -- I assume there is some PHP list to post specific questions to...

I saw on another Web page that php4 is the only file that matters, so I'll try that this afternoon. But it seems that a lot of other files are generated, too. typically, a lot of intermediate files are being created (e.g. for every source file (.c) there'll be an object file (.o) ). The configure process itself also creates a couple of temporary files. You don't need to worry about all those... Very generally speaking -- if we leave out any config and documentation files for the moment -- the target of the build process will usually be one or more of the following: (1) a binary executable (typically named after the package), (2) a static library file (extension .a) or (3) a dynamic library, also called shared object file (thus the extension .so). Library filenames by convention start with lib. If I understood you correctly, you're trying to build the dynamic php4 module to be loaded into apache. In this case you probably only need the libphp4.so shared-object file. After a successful build you can fish that out of the .lib subdirectory (IIRC), that should've been created in the source directory while building. Then simply replace the other file of the same name (the one which refuses to work) with this newly created one -- it should reside in /usr/lib/apache/1.3/. The php4 file you mentioned above is the stand-alone PHP binary for use in conventional CGIs. I guess this is not the one you're interested in ;) If you'd rather like to try the automatic install, after having set up the appropriate destination directories, but are still feeling a little unsure about where stuff will be installed into, you can always try the generic dry run facility of make (option -n), i.e. make -n install (instead of the usual make install). This is supposed to cause make to just print out what it *would* do without actually modifying anything... It doesn't always work as desired under every circumstance, though (i.e. if in intermediate steps some files need to be put in their proper places to be able to continue with subsequent installation steps...), so YMMV. But even then, you'll get a rough idea of where stuff will be put, when looking at the directory names in the commands being printed during the dry run...

which version of the rtl8139.c driver are u using?
When comparing the init_module()-fragment of the rtl8139.c that came

v1.07:
int init_module(void)

v1.16a:

...I somehow get the impression that CARDBUS support might not have

worth trying a newer version. Not sure, though, whether the new

There isn't much to lose ;) If the most recent version doesn't

The essential idea is to incorporate a secret key when computing the checksum -- in its most simple form something like the following pseudo code: $hash = md5sum( $secret$data ) $ticket = $data$hash To verify the validity of the ticket, just seperate the data and hash part, and check whether the hash matches the real one which *only you* can compute using your secret key (as shown above). As hashes like MD5 are *one-way* functions, it's infeasible (within the general limits of cryptography) to reverse the operation to obtain your secret key. Of course, many variations on the theme exist...

Hi Will,
...as I've seen you being active on the mod_perl list, I would've
assumed that you've already heard of The Guide ;)
Basically, there's nothing wrong with your concept of forking off the
long-running process, and as a normal CGI program it would probably
work fine. The few remaining flaws in it (specific to the mod_perl
environment) are all detailed in the mentioned docs.
So, just in case you'd like to pursue your original idea (instead of
using the multipart/x-mixed-replace MIME-type method), you probably
want to start reading here:
http://perl.apache.org/guide/performance.html#Forking_and_Executing_Subprocess
Also, if you haven't already thought of this, you might consider
sending back a 'waiting'-document that automatically keeps pulling the
server in certain intervals. Just include the following in the HEAD
section of that html page
HTML
HEAD
META HTTP-EQUIV=refresh content=5; URL=...(your URI here)
/HEAD
...
to have it check back/reload after 5 secs. In the most simple case, the
remote process you call via this URI would check whether there exists
some result file (indicating that the long running process has
completed), and, if so, send back the final result page, if not, resend
the wait page.
What also often comes in handy is the not so well known HTTP return
code Status: 204 No Content, which causes the browser to *not*
update/delete its currently displayed page -- it's a kinda 'do nothing'
instruction. For example, returning this 204 while the process is still
running, avoids having to resend/redraw the wait-page, and the
associated flickering...
The above refresh technique does, however, not work in combination with
the 204 trick. It would reload exactly once, as the no content-page
cannot resend the same html code snippet, of course (and sending a real
HTTP Refresh: ... header after the the Status: 204 does not seem to
work -- at least not with Netscape. So, for this to work, you would
need a bit of javascript, something like:
HTML
HEAD
SCRIPT LANGUAGE=JavaScript
function check_done() {
this.location.replace(http://your.server/path/check-done.url;);
}
/SCRIPT
/HEAD
BODY onLoad=setInterval('check_done()', 5000)
Processing... Please wait...
/BODY
/HTML
(the setInterval() period is in msecs)

At the moment I don't really need the info -- but who knows when the time comes ;) ...but hell if I know how to apply them. I'm using lpr. I remember some stuff from way back when I ran on HPUX that we'd throw a slew of options at the printer with jobs for various output options (usually portrait/landscape orientation). I'm hoping that I can do something here either with a '-o' option or with a printcap configuration. If I were in the situation, I'd start my first experiments by cat-ing the stuff directly to the printer device to avoid having to deal with the lpr system at this stage of experimentation. I'd write myself a little script to ease transferring the information from the above webpage to my printer. It could look something like: #!/usr/bin/perl my $manual_feed = pack H*, join , qw(1B 26 6C 32 48); # $manual_feed now is a 5-byte binary string representing the # PCL escape/control sequence for manual feed print $manual_feed, ; This does nothing more than assembling the escape sequence specified in hex notation (as found in the last column of the table on the webpage) into the (binary) string that needs to be sent to the printer. This string is then simply prepended to the data to be printed. The script can be used as a pipe or be called with argument(s) representing the files to be sent to the printer. It's meant as an example only -- with a hardcoded PCL sequence for selecting the manual-feed paper option. (The idea is just to make it easy to cut paste the sequences form the webpage without too much editing...) Once you have the PCL sequences causing the desired effects in the printer, you could proceed to the next step, which would be the question how to integrate that into the lpr system. Basically, I'd try to use printcap's facility to specify filters. In this particular case it wouldn't matter much whether you use the 'if' or the 'of' filter (though, if you already have a filter configured, you'd somehow have to chain/merge their effects, of course, e.g. by making one filter a wrapper for the other...). Also, IIRC, the 'of' filter will only get called when there's no 'if' filter -- see the manpage for details. The filter would be a script resembling the above example. Theoretically, the filter could be passed some options that would control its detailed behaviour (manual-feed, tray-1, tray-2, etc.), yet there remains the problem of how to get the option to the script. I'm not aware of a general option passing facility in the lpr system -- the '-o' is specific to the lp system, AFAIK. Yet, I may simply not have been reading the manpage carefully enough ;) So, I assume it would get quite cumbersome to pass some custom options to the filter. The easiest workaround would probably be to setup several, differently named printers in printcap (which would all be printing to the same physical device), specifying a different filter for each one, which would take care of prepending the required PCL control sequences. Selecting a paper tray would then be matter of specifying the dedicated printer (alias) via the usual -P option. Someone else might have a better idea... Also, more generally, the whole approach of simply *prepending* some PCL escape sequences would not be able to deal with data already containing conflicting PCL code, as might be generated by some applications. For example, if an application insists on generating PCL code to select tray-1, this would simply override any attempts to select manual-feed, etc., as the 'tray-1' code appears later in the stream sent to the printer...

Preferably do a make distclean before you rerun configure (occasionally I've seen configure getting confused by its own config.cache, which will also be removed in the above step). Then try again what you had probably done before: ./configure --with-imap [other options...] It *should* complain in case it doesn't find the imap stuff... ;) What's a bit strange is the presence of the '-limap' in the linking step (as shown in your log below).

It is apparently supported in the kernel distributed with the current Potato release. I have read that it should be auto-detected. It doesn't seem to be detected and set up in the Debian Install. How do I go about configuring it? Try disabling the Plug-n-Play Operating System setting in your BIOS, if you have one. It may be worded differently, but you should get the idea... I *think* (and I'd like to know the answer for sure in case anyone knows) that the kernel drivers for various pieces of hardware only looks at 'x' number of settings, i.e. IRQ and IO address. They're considered 'standard' settings for that particular device. If you have 'PnP O/S' setting enabled in your BIOS, it doesn't assign the settings, but instead, lets the operating system do it. I recently fought with a similar problem while trying to get the NIC of my new notebook working (an ASUS L8400K with onboard RTL8139 chip). I'm not entirely sure whether this has much to do with the original problem -- but anyway, just for the record: The card was being detected and I could load the appropriate driver module. But when trying an ifup or ifconfig, I always got a SIOCSFFLAGS: Resource temporarily unavailable. A google search provided converging evidence that this has to do with an IRQ conflict, which made me take a closer look at the messages being output while the card was being detected. There I saw, that the PCI BIOS had assigned IRQ 0 (!) to the NIC -- no surprise there were conflicts... Further googling revealed that this is a M$-made PnP issue, so I looked for a way to disable PnP in the BIOS. Unfortunately, it took me while to realise that this ridiculous Win98/W2K vs. Other OS option in the Phoenix-BIOS (which I had not taken seriously before) really meant: PnP enabled vs. PnP disabled... Setting it to Other immediately solved the problem. To quote one of the NIC driver gurus, Donald Becker: The PnP OS problem occurs because Microsoft has convinced BIOS makers to modify their PCI device configuration from the previous rational standard, to one that works well only with Microsoft operating systems. Where previously the BIOS allocated resources for and enabled the PCI device by default, it now does so only for boot devices and audio devices. (Why are audio devices specifically an exception? Because MS-Windows can't handle the resource allocation for them!) The solution is to either update to the latest driver, (the drivers are being re-worked to enable the devices) or to disable the PnP OS setting in the machine's BIOS setup. The reason Microsoft had to have this change implemented for them was that MS-Windows still handles some devices with real-mode drivers, and this change makes it easier to mix real-mode and protected-mode device drivers. This is an excellent example of Microsoft using its dominant position in the software industry force a technical change that is detrimental to other operating systems.

you might want to check whether the device driver ('stcolor', maybe

(put your gs-version here)
If there is no such option, you might consider tweaking the printer
init code sequence to include the ESC-sequence that enables economy
mode (you'd have to look that up in the printer's manual).
The init sequence can be overidden (not appended) with the option:
-sescp_Init=ESC-string
Printing at a lower resolution (e.g. -r180x180) might have a similar
effect as 'economy'. YMMV.

Hi,
in the postscript drawing model there is a clean seperation between
constructing the paths that define the shapes to draw, and the actual
rendering. The paths can be imagined as invisible descriptions of the
shapes, while the rendering process then puts some color onto the
virtual page. The rendering itself can basically be stroking (like
taking a pencil and moving/putting color along the path), or filling
the area circumscribed by a closed path.
Actually, there are three steps: (1) path construction, (2) rendering
and (3) transferring the internally built-up page image onto the
physical paper or some other media.
Now, how does that relate to your problem? If you want to stroke the
path (the square in your case) you need to tell the postscript
interpreter which line width, line style, etc. you wish to use. In the
example below this didn't happen anywhere, so the interpreter uses
some built-in defaults. These are device-dependent, i.e. they can vary
from printer to printer. Typically the default line width is set to
the device resolution. So if you have a 600dpi printer, the lines will
be 1/600 inch wide, whereas, if you let ghostscript output the page
to the screen, the same line will usually be one pixel wide.
But these are just the defaults. You can of course set any desired line
width, and the postscript interpreter will try to approximate that
thickness as good as possible at the given device resolution.
The operator for setting the line width is, guess what, setlinewidth ;)
The units in which you specify the width is by default 1/72 inch, but
you can change that as well.
Thus to get a line width of, let's say, 5/72 inch, you simple put
5 setlinewidth
somewhere before executing the stroke operator, as I've done in your
code below. The exact place is not so important as long as it's before
the stroke, so putting it before the newpath would be equally fine,
for example. You can specify _any_ width, not just integer multiples of
the unit currently in effect. So, something like 1.35 setlinewidth is
ok, too.
In case you'd rather wanted to use mm-units, you could put
72 25.4 div dup scale
at the beginning of the postscript document, etc. etc. ...
So, if you write your (simple) documents from scratch, things are
basically quite easy and flexible. On the other hand, if you'd have to
manipulate some third-party postscript document, it can of course be
considerably harder to find the correct place to modify...
If you feel like doing more advanced things than drawing a simple square,

Re: Corruption many (unknown) files; how best to restore?
On Sun, Apr 22, 2001 at 09:37:55AM -0500, Kent West wrote: Hi all. HISTORY (the actual question is below): For some reason my Sid box at home has been locking up in X lately. I don't know if it's an X problem, or a hardware problem, or what. I'm running 2.2.18; have been for months without any problem, so I doubt it's any bug within the kernel. I've just run memtest86, and it seems that my RAM's fine. I had a hard drive fail a couple of months or so ago; I pulled it out and replaced it (it had /usr and /home on it) and rebuilt as best I could; I think I got it working. Then last week I put that failed drive back in to see if I could recover any data off of it before consigning it to it's eternal resting place. After finding a bay to rest it in and plugging in an IDE data cable, I realized I didn't have any extra power plugs for it. So I left it that way until I could get a power splitter. I figured that not having any power to it, the system would ignore it. I'm afraid that not having the power cable attached to the drive _may_ have been the initial cause for the lock-ups you're experiencing... I once created myself a similar problem on a SCSI-based box simply by attaching a fairly long external SCSI cable to connect my scanner. Obviously, the cable was too long, as it apparently deformed the electrical impulses on the SCSI bus in such a way that sector adressing of the drive happened to continue to work but in a more or less random fashion! Now, I don't have to elaborate any further on what that means in terms of file system corruption... Actually, hundreds of files got corrupted :( The strange thing was that I didn't get _any_ error messages from the SCSI subsystem -- after attaching that harmful cable, I was able to work happily for another quarter of an hour in GIMP before the system finally completely froze (and interestingly, the scanner did work). Post-mortem analysis of the corrupted files revealed, that the data I had written to disk during that quarter of an hour seemed to have been randomly scattered all over the file system, doing its destructive job as thoroughly as possible... I'm sharing that story because my educated guess would be that the freely floating drive (as to electrical charge) in your case might well have had affected the signals on the IDE bus in a similar way. Hopefully not as thorough as in my case ;) ( Also, while we're at the topic, my advice to anyone playing with the idea of exceeding the maximum recommended cable lengths for whatever reason: just don't do it! Or have a recent backup :) I think maybe my suspicion was incorrect, and that the system saw this drive and got confused and started doing nasty things. I shut down and unplugged the drive, and restarted the system. Everything looked fine, except that KDM no longer started an X session; it acted the same way that it would if there was something wrong, like a wrong mouse section, in the XF86Config file. But I could start X with the startx command, so I just figured it was some glitch I downloaded with my most recent upgrade of Sid. Nevertheless, since then I've started having lockups in X. It may be related to a Windows-based Backgammon game I'm running via Wine (this game typically bombs now, whereas it used to work fine). To make this (very) long story short, the repeated crashing and subsequent resets (no way to ssh/telnet in, and loss of keyboard control) has tended to do nasty things to my file system. ACTUAL QUESTION: I don't know which files/packages are corrupt; is there any automated way to have the system check to see what's installed, what's broken, and what needs to be reinstalled to fix what's broken? I would check my most recent MD5-checksum filelists against the existing files to produce a list of what's damaged -- hopefully you did create MD5 lists while the system was still working properly? ;) That doesn't solve the automatic reinstallation part, though. Maybe someone else has a better suggestion. Anyway, it's a good moment to reconsider installing a tool like tripwire (www.tripwire.org) -- or if you think that's overkill, run something like find / -type f | xargs md5sum files.md5 periodically...

Re: can't print from acroread
On Fri, Mar 23, 2001 at 01:20:10PM -0800, peanut butter wrote: (...) To really simplify things while exposing the basic problem, I saved the pdf from acroread as a postscript file. I then wrote one script that prints this postscript file with the lpr -D5 option saving the output to one file while recording the returned status from lpr to another. I then ran this exact same command once from the command line and once from within acroread. Now, mind you, the script accepts no input arguments . . . so the execution of the script is exactly the same, printing the exact same postscript file, while printing correctly from one execution (command line) yet not from the other (acroread). good idea... I can offer the full debug report from either or both runs to anyone who should care to view it/them but in attempt to keep things as concise as possible, just below is the segment from both reports where they begin to deviate. thanks for the clear report. From this debugging information and a quick look at the lprng source, I would say that the problem occurs while trying to fork/exec the so-called input filter, though I do not yet have a clear idea why it fails... The waitpid(2) call returns a -1, which indicates that the waitpid failed. Actually, there are three error/return codes involved here: the exit code of the waited-for child process (the filter), the return code of the waitpid function itself, and in case the latter returns -1, the errno being set by waitpid, which _might_ provide further details on what went wrong (not sure whether it really would in this case, though). Unfortunately, this error number doesn't seem to make it to the debugging logs (or else we should see another diff) -- the -1 appears to be propagated to the logs instead. Although it would generally be easy to add another printf() to the lprng code, outputting the errno, I assume that you would rather avoid having to recompile the code and having to make sure that the modified version gets installed in the appropriate place. I guess we should do things like these as a last resort only. Instead we might try to apply the same wrap a script-technique here as well, by substituting a script for the filter program run by lprng. The script could output a few interesting things like command line args, environment, the errno in question, etc. before/after running the filter... There is a faint hope that something will differ here... :) First, however, I'd like to take a look at the full logs available already, so feel free to send them to me privately. In particular, I'm not sure yet as to how the other diff (the fd-0..5 vs. fd-0..8 thing) is related to the waitpid error ocurring later on. Maybe that is the real place where things start to go wrong. The complete logs will make it easier to dig through the appropriate portions of the source. Also, I'd like to take a look at your printcap file (especially the if-specification which is in effect for the printer in question), so be sure to attach that as well. BTW, which printer are you using -- is it a native postscript printer, or are you using ghostscript as a filter? If you haven't done so already, you might also want to try to run your test script from the command line but in the background. This might help to rule out issues with a controlling terminal being required by the filter. Don't know why it would need one, but who knows ... just an idea. Erdmut PS: I cannot promise to be able to take a closer look at this immediately, but I _will_ as soon as time permits. After all, getting a deeper understanding of the lprng mechanics might help me to eventually solve a somewhat similar problem I'm experiencing myself sporadically ;) -- Erdmut Pfeifer science+computing ag -- Bugs come in through open windows.

Can you view the resulting PS-file in ghostscript? Yes to both. Sorry not to mention this right off. I mentioned this the first time I attempted to post this message but apparently wasn't yet fully subscribed and neglected to save myself a copy. If I save the file as a postscript from the acroread print pop-up window, I can print the job without a problem from the command line and, thus, to no surprise, can also correctly display it with gv. Thus, the job seems to somehow never be making it outside acroread. In trying to diagnose the problem, I tried using another printer that I didn't realize hadn't been configured for the system by changing the printer command to /usr/bin/lpr -Plex. I received the same print error message I would have received from lprng if I had tried this from the command line yet it was displayed within a pop-up window from acroread. So obviously acroread is talking to lprng to some degree. well, this is really a little strange... Perhaps you might want to try the following to get some more information: Write a shell script something like #!/bin/sh ls -l $1 /tmp/acroprint-debug.$$ cp $1 /tmp/acroprint-out.$$ /usr/bin/lpr -Pprinter $1 # substitute your printer here echo $? /tmp/acroprint-debug.$$ (the .$$ are not required, they just create a seperate pair of files for each try, with the PID appended) and run this instead of the /usr/bin/lpr from acroread's print dialogbox (e.g. Printer Command: /home/name/test-print -- no further options) This should (a) give you some info about the temp-file that acroread creates (- ls) (b) copy the temp-file to a safe place, before it gets deleted (- cp) (c) try to run the actual print command -- maybe it works from here (d) capture the return code of the print command -- should be 0 if OK Then you can also compare the /tmp/acroprint-out with the file you created when printing directly to a file from within the dialogbox. I guess both files should be identical. Also, feel free to add other debugging commands you could think of to the script...

I am a little confused about the structure of the crontab command that refers to the daily, weekly, and monthly cron schedules. Since anacron is installed on my system, 'test -e /usr/sbin/anacron' returns 0.

Normally gs should just load the svga shared lib, but not start reading
related config files, etc. However, the fact that in your case it does
proceed as if it wanted to init the svga driver, makes me guess that
there might be some problem with the device specification in the gs
command (that's why I asked for that exact command). In that case it
would be possible that gs falls back to the built-in default device
(x11 when in X, and that stupid svga thing when in console mode).
To clarify this further: what happens if you take the following
trivial PostScript fragment
%!PS
/Helvetica findfont 36 scalefont setfont
10 10 moveto (testpage) show
showpage
and for example run the following gs command
gs -sDEVICE=jpeg -sOutputFile=test.jpg -g150x50 -dBATCH test.ps
(assuming you saved the PS under test.ps, of course)
This should create a small jpeg file without messing around with
svgalib. When I run something like this under strace I don't see
anything like what you get above before it fails.
Does at least that work for you or do you get the same error?

Re: after 'su -', 'Can't open display'

Hi, By default the Xserver doesn't listen to the tcp port (for security reasons) and I'll guess thats the reason for your problem. I've added the following few lines to the /root/.bashrc file: if [ ! $LOGNAME = root ] ; then export XAUTHORITY=/home/$LOGNAME/.Xauthority fi This works for me. ... but it didn't work for me. Please forgive my ignorance, but I don't really understand what this will achieve. If I execute 'su -', then $LOGNAME in the child bash shell will be 'root', the expression '[ ! $LOGNAME = root ]' will evaluate to false, and so nothing will happen, as far as I can see. So I don't see what difference it makes in my situation. I guess, something like the following should work: su - root -c export XAUTHORITY=/home/$LOGNAME/.Xauthority; exec /bin/bash -i The difference is that LOGNAME gets expanded before you are root. Put this in a script or create an appropriate alias... e.g.: #!/bin/bash exec /bin/su - root -c export XAUTHORITY=/home/$LOGNAME/.Xauthority; exec /bin/bash -i (the syntax for setting XAUTHORITY depends on the login shell flavour, of course, i.e. whether to use export... or setenv..., etc.) Cheers, Erdmut On Wed, 21 Feb 2001, James Sinnamon wrote: Dear Debian user's, My apologies for a question that should have been answered over and over again on this list (I have searced but not been able to find an answer), or if I am on the wrong list.

Is this type of thing done thru the use of cgi scripts or what. There is probably more than one way to do it but I'd be interested in some opinions in a good way to accomplish this. don't know what kind of calculations you offer and in what way the javascript is involved, but if your requirements fit into the scheme of having some kind of form into which the user fills in several parameters before clicking calculate, then the classical CGI script would probably be the best solution. In that case, everything you might want to protect - data, algorithms, whatever - is on the server side, and you can easily control at which point you require authentication/ authorization. When doing it in javascript (client-side, I assume), keep in mind that the code is delivered to the browser as is, so you have no real control over what the user then does with it. If this code implements the calculations you would like to protect, then this probably isn't the best way of doing it (it only requires very little expert knowledge to get that code executing outside of the context of your website, except if you devise some clever challenge-response mechanism). However, these concerns only apply if you are _not_ having some data on the server side without which the javascript would be useless...

Re: [OT] perl regex problem

I am a long time debian and perl user. But obviously long enough!
Forgive the slight misuse of the list, but can anyone shed light
on what I'm doing wrong in this attempt to find \n\n in a text file
with perl? I'm sure I've done this before.
Hi,
depending on what exactly you want to do, it might help to set the
input record separator ($/) to something other than the default \n.
If you set it to \n\n for example, the input lines you get will
be broken up at double-newlines...
#!/usr/bin/perl
$/=\n\n; # set input record separator
while () {
# every line ($_) will inlcude everything up to and including
# the \n\n, so you can match against it (if still needed...)
if (/\n\n/) {
print yup\n;
}
}
The input record separator can be any string, but it's _not_ interpreted
as a regular expression. If you need that, you can read the whole file
into a string in one go (if it fits into memory), and then do any kind
of processing on it, e.g. split() or repeated regex matching
#!/usr/bin/perl
$/=undef; # 'undef' causes whole file to be read in
$s = ;# file now in $s
while ($s =~ /\n\n/g) { # do some repeated matching
print yup\n;
}
The advantage of the latter approach is that you can craft your
regex to do any kind of sophisticated matching, independently of some
concept of line termination...
BTW, if you don't want the modification of the input record separator
to apply globally for the script, you can use local $/ =... instead,
in soubroutines, for example (my doesn't work here).
Cheers,

I have tried 'mb', didn't help. I just tried to reproduce your problem, but everything seems to working fine over here... That doesn't mean too much, however (we might be using different versions of whatever is involved). I'm afraid that this is not going to be easy to solve, but at least you may be able to narrow down things a little. Basically, the problem may be caused on either side of the X connection: (a) your debian-side X server may no longer send the appropriate X events (at the time cut-n-paste stops working), or (b) the X client (the hpterm on the HP-UX box) may not process the events properly To further clarify which side is responsible, you'd have to intercept the connection from the hpterm to your X server, and take a closer look at the X protocol messages to see whether the events in question are still being sent. I could give you a simple Perl script that more or less does just this. It dumps the names of all X protocol requests and events being exchanged into a file (in human-readable form). From this you can get a rough understanding of what's going on. There may be other tools out there for debugging X sessions, but for the purpose at hand the script will probably do fine... Email me privately if you are interested -- this is slightly off-topic anyway (except that it turns out to be a Debian-specific X server problem), so I think we shouldn't bother the list with all the details. It is very difficult to live without cut-n-paste. I tried using 'xterm', but that doesn't have 'smooth scrolling'. in 'xterm' and 'dtterm' cut-n-paste always work. I don't like the appearance of 'dtterm'. My libc version is : libc-2.1.3.so and ncurses version is 5.0-6.0. the debian-side ncurses certainly is not involved, the libc might be involved indirectly (via the X server using some functions of it), but what would probably be more interesting is the version of the X server you are running :) HTH, Erdmut -- Erdmut Pfeifer science+computing gmbh -- Bugs come in through open windows.

Hi all,
Someone knows where I can get the default behaviour of characters

In man xterm it sais about class CharClass, but it refer only to
0-127:
The default table is
static int charClass[128] = {
/* NUL SOH STX ETX EOT ENQ ACK BEL */

48, 48, 48, 123, 124, 125, 126, 1};
Info xterm give the same answer as man xterm.
this seems to be a highly version-specific issue. The newer versions
of xterm seem to support the full 8-bit charset and even unicode
in CharClass definitions.
To quote from the manpage that comes with the most recent source
distribution of xterm (e.g. http://dickey.his.com/xterm/xterm.tar.gz):
(...)
CHARACTER CLASSES
Clicking the middle mouse button twice in rapid succession
will cause all characters of the same class (e.g. letters,
white space, punctuation) to be selected. Since different
people have different preferences for what should be
selected (for example, should filenames be selected as a
whole or only the separate subnames), the default mapping
can be overridden through the use of the charClass (class
CharClass) resource.
This resource is a series of comma-separated of
range:value pairs. The range is either a single number or
low-high in the range of 0 to 65535, corresponding to the
code for the character or characters to be set. The value
is arbitrary, although the default table uses the charac-
ter number of the first character occurring in the set.
When not in UTF-8 mode, only the first 256 bytes of this
table will be used.
The default table starts as follows -
static int charClass[256] = {
(...)
I can't tell you the exact version in which support for this was added.
If you are interested in all the details, you might want to browse the
changelog at
http://dickey.his.com/xterm/xterm.log.html
(though that's probably more than you want to know :)
Also, if you are not afraid of reading the source, have a look at
the file charclass.c from the source distribution...

(..., ...) ... didn't see too many responses yet, so I thought you might be interested in some more comments: I'm not sure whether I understood every detail of what are trying to achieve, in particular why you would want to bring the Apache into play. But, if I didn't misunderstand you too much, the best/most simple solution (imho) would be to leave the Apache out of the whole business and do a transparent TCP proxying (some prefer to call it port- forwarding) in your DMZ, so that the SSL packets get directly routed to your IIS server, which will then do everything else -- authentication, authorization, content serving, etc., just as you have it right now. Although I feel tempted to sell you an Apache-based all-in-Linux solution :-) , under the given circumstances, it's probably preferable to not touch a running system (at least if it is... :) With this solution your main task would be to talk to your firewall expert, and have him set things up appropriately. The new 2.4-kernel netfilter/iptables architecture offers very flexible configuration options, though mere port-forwarding should not be a problem for older kernels either. (I'd rather not give you any recipes here, because I'm definitely not a firewall expert :) I think the main issue boils down to the question, at which point to do the de-/encryption of the SSL protocol. With the above solution you'd leave that to the IIS. The TCP proxying would occur at a relatively low level, without any knowledge of the application-level protocols (HTTP(S),SSL), which means that the proxy won't be able to inspect URLs and HTTP headers, do caching of the content, or whatever else you might think of. All information you have (and can control) at this point is basically: IP address and port number -- the rest is simply tunneled through encrypted. If you really need to do proxying at the application level, then (and only then) the Apache+some-SSL reverse proxying solution would make sense, imho. In this case the Apache would handle the de-/encryption for the outbound side. This however seems to be the hardest way... especially if the IIS were still to speak HTTPS, for then, everything would have to be re-encrypted before sending the request to the real content server. Afaik, the usual Apache/mod_ssl/mod_proxy bundle would not be able to handle this reencryption, anyway, without doing some real programming (if anyone knows better, let me know...) On the inbound side (proxy--IIS) you might also consider using HTTP instead of HTTPS, which would considerably simplify things. That would, of course, depend on your LAN-internal security policies... Depending on where authentication/authorization is supposed to occur (I guess your database is involved here), you would, however, have to devise some means of passing on the relevant information you extracted from the client certificates, for example by using the basic authentication method from HTTP. I think I won't elaborate on this any further, as I anticipate that this is not really what you want... So, to sum up, I'd simply let the firewall machine forward the packets which are destined for port 443 and are originating from the allowed hosts/customers. (Another assumption: Opening the firewall for https-traffic on port 443 is just as dangerous as opening for http-traffic on port 80. Again: correct me if this isn't true.) this is mainly a question of the protocol spoken at the port and the application behind it, not so much the port number... :) I've had a look at Apache-SSL. But some recommend to use Apache and mod_ssl instead. Which one is the best, and which proxy server works best in cooperation with SSL? at the time I had to make that decision between Apache-SSL and Apache+mod_ssl, I tried both, and both worked well. I then decided to stick with the mod_ssl solution (for some minor reasons) and haven't had any problems since. (But that might not be relevant, anyway.) Hope that clarified things a little...

For example if you get a new soundcard you only have to insert the new module, you don't need to recompile the whole kernel. I expect there is a few picaseconds latency when the module is first loaded :) Other than that I should think not. It depends on what you're talking about. Take, for instance, the Intel EtherExpressPro100 (eepro100) network card. Loading it as a module on a HEAVILY laden web server exposed a major weakness in the overall robustness of the card. The card started dropping packets and causing collisions under only 50% of what the interface would have been capable of if it were built-in to the kernel. why is that (just curious) -- has anybody got an idea? Afaik, the only performance related difference between static and shared object code (once the module is loaded) comes from the requirement of .so-code to be 'relocatable', which means that a few extra machine code instructions need to be generated by the compiler. The performance decrease is normally negligible, according to my experiences far below 10%. So, either the code of that module is somewhat weird, or there is some highly nonlinear interaction between CPU load and network throughput... In that case, I would expect the same drop in performance with the static module version when the load rises just another few percent above the point where the dynamic version gets into problems... any other explanations?

Note, however, that this might not work _by default_ under all circumstances... -- it usually requires setting lib-paths, environment variables, etc.) Then, you could immediately do a quick check to see whether the loading of the new libs really works: perl -MLockFile::Simple -e '' (or equivalently: perl -e 'use LockFile::Simple' ) This should return you to the command line without any error msgs, in any case you should _not_ see something like: Can't locate bla-bla in @INC (@INC contains: bla-bla ...) One word of caution: except if you really know what you're doing, try to make sure that there's _only one_ Perl installation/version on your system, or at least that you do get the one you expect when you type a simple perl -V (at the end of the output you get from this, you should find the installation paths for the perl libs and binaries...)

a small wrapper script (in Perl -- I know one could do that in at least

}
# run your favourite grep or whatever here:
system grep @ARGV;
# restore atime/mtime for all files
foreach $f (@times) { utime @$f; }
You would call it more or less like grep. Assuming you name it mygrep:
mygrep [options] search-regex files...

The script assumes that you have the same number of leading lines in both

In your sketch of the file contents, however, it looks as if there is one
more leading line in the output file. If that's not just a typo, you'd
have to make a small change to the script to make corresponding rows align.
Let me know if you can't figure it out yourself...
Call it like this:
script list of .pdb-files to change
e.g.
script *.pdb
(where 'script' is the name you choose, of course)
Corresponding input files are assumed to reside in the same directory.
Original output files will be renamed to '*.pdb.bak'.

What does gs -h show under Search path:? In one of those paths, your ghostscript type1-fonts should reside. These need not necessarily be the ones used by X, because (afaik) ghostscript does its own font rendering ( that's also why you could already have anti-aliased font rendering (by specifying the appropriate gs-driver 'x11alpha') before X was able to so... ) Also, ghostscript has its own config file for mapping fontnames (eg. Helvetica) to filenames (*.pfb or *.pfa) and defining aliases which map one fontname to another, eg. /Helvetica to /NimbusSanL-Regu. The file is called Fontmap and can be found in the directory where ghostscript is installed (.../ghostscript/version/Fontmap, I assume) The default configuration should, however, be set up reasonably, so at least the usual fonts like Times-Roman, Helvetica, etc. should work... So, I guess, you either haven't yet installed the gs font package, or for some reason it ended up where it isn't found -- unlikely.

you seem to be having a version problem in your Perl installation,
which probably has nothing to do with debconf. I suspect you will get
the same error when you simply try to run
perl -e use Data::Dumper;
which just loads the module in question (if everything goes fine,
this command should not output anything...)
If you do get a version mismatch message similar to the one above, I
would guess that you have an ancient version of the module Data::Dumper
somewhere on your system, which for some reason gets pulled in before
the one that comes with the recent version of Perl (Data::Dumper
version 2.101 has been out since April 1999)
A little background info: Every architecture dependent Perl module like
Data::Dumper consists if two parts:
the Perl-side module (.../Data/Dumper.pm) and the architecture-specific
shared object file (.../arch/auto/Data/Dumper.so) that gets pulled in via
the Dynaloader module. Both parts have to be exactly the same version, or
else you get the above message...
In your case, the 2.101 belongs to the .so-file, while the 2.09 comes
from the .pm-file, which indicates that the Perl-side .pm-file is the
wrong (older) version.
You might want to try running the following statement, which should tell
you, in which directory the file is being found:
perl -e 'for (@INC) { print $_\n if -f $_/Data/Dumper.pm;}'
(If you have a look into the source of this Dumper.pm you should find
something like $VERSION = '2.09' at the very beginning...)
The search path where Perl looks for (.pm-)modules is determined by
the @INC-Array, which again may be manipulated by setting the environment
PERLLIB or PERL5LIB (among other things).
Maybe the place where Dumper.pm is found will give a clue as to what
is going wrong... (old version lying around somewhere, etc.?)
Other useful commands that might help to clarify things include
perl -V (for search paths etc.)
or setting the environment variable PERL_DL_DEBUG to 1, which should
trigger the Dynaloader to output a little on what it's doing...
(You might also try wether you get different results from running
perl -V versus /usr/bin/perl -V, which would indicate that
you have several Perl versions (binaries) on your system/search path)

I have the following (among some other function and structure

This function is in file 'scanner.c' and does the following:
#include bet.h
struct provided_data *read_data(char *input_file_name)
{
struct provided_data *prov_data_buffer;
Read in some data and put them into structure provided_data.
Then return pointer to structure provided data using the
following statement:
return(prov_data_buffer);
}
In file main.c I have the following:
#include bet.h
int main(int argc, char **argv)

some code that reads commandline opts and so on.
Here I define input_data:
struct provided_data *input_data;
Now call read_data:
--- input_data=read_data(input_file_name);
}
line marked with --- is the line, the compiler complains about.
I don't quite understand this, because I never declared function read_data
to return an int. Is something wrong with my function declaration?
sorry, I can't tell you what the problem is -- doesn't seem to be
in the syntax. My gcc (egcs-2.91.66) doesn't have any problems with
this code fragment.

Re: Perl @INC - include NFS mounted repository
On Mon, Sep 18, 2000 at 11:26:02AM +0200, Thomas Gebhardt wrote:
Hi,
I'd like to include a NFS mounted repository (actually a very
comprehensive Debian installation) into the Module Search Path
of Perl.
Boundary conditions:
* transparent for the users
* Modules that are also locally available should not be loaded
by NFS.
Hi,
there are several ways of achieving this, although none of them
is without drawbacks:
(1) you can setup the PERL5LIB environment variable (or PERLLIB
if you want it to apply for both Perl4 and Perl5) to contain
the appropriate search path for the Modules (a colon-separated
list of directories)
If you want local modules to be found first, just put the NFS
directory at the end of the path list.
This method has the disadvantage that you somehow have to make sure
that PERL5LIB gets set in the environment of the individual users.
This is basically a system administration task. You might consider
one of the following strategies:
* put PERL5LIB in the system-wide login-environment, so users do
not have to set it themselves
* have users set it by themselves (error-prone)
* write a wrapper script around the call of the perl binary that
sets the environment
(or whatever else you could think of...)
(2) you can modify the @INC array at the beginning of your perl
scripts. To have the NFS directory be found last you would
insert the following code snippet:
BEGIN { push @INC, /your-NFS-libpaths-here; }
(this gets executed before any use or require statements,
so the modified include path applies)
You probably want to include both the normal path (for Perl-only
modules) and the path for architecture-specific modules
(containing e.g. something like i686-linux), although
the latter is not always required (just try and see...)
This obviously has the disadvantage that all of your scripts have to
be modified, so depending on how much scripts you have and whether you
could edit them automatically, this approach might not be feasible.
There may be other ways that I'm not aware of, e.g. fiddling around
with symlinks in the ordinary perl lib-dir or changing the compiled-in
lib-path...(?); but as far as I know, this way its not possible to
achieve the kind of fall-through behaviour you need.
(if anyone knows how to do this, I'd like to know)
Good luck,

I'm not sure whether I understood in every detail what you are trying to

be served if a user requests e.g.
http://www.virtualhost1.com/stats/index.html ( is it the file
/var/reports/www.virtualhost1.com/index.html ?)
If so, the combination of rewrite and Alias (as you originally had it)
should do the job when you specify [PT] -- and only then [PT] is needed.
In this case the Alias statement may map to any path outside of the
DocumentRoot. So when using
Alias /reports /var/reports
the rewritten string (not the document root) would have to supply the
host part.
When using the RewriteRule alone, you would have to make sure that the
string portion, which comes out of the rewrite rule, will give the final
document path when concatenated to the DocumentRoot. For this you would
either have to use a different DocumentRoot or a different rewrite rule
to avoid getting the duplicate occurences.
