Subject: 501 error from www server
Message-Id: <6ds435$2ol$1@ha2.rdc1.sfba.home.com>
I am trying to do a POST to a web server running Apache.
I have the LWP code and it worked till the server was changed.
Here is the POST code I am using:
my $req = POST 'http://$user:$pw@//<host-name>/index.cgi',
[proc => "retrieve",
retrieve => $code,
usr => $user];
local ($got_it)=$ua->request($req)->as_string;
This method worked with "Server: Apache/1.2.4 mod_perl/1.00"
They have changed the server to be "Server: Apache/1.1.3" now it does not
work Error 501 is returned.
If I take the post information above and build a html page from it (I have
valid data for the $vars) It works just fine!
Anybody?

Message-Id: <34FD2BEA.390DF995@pitagora.it>
Hi!
I have a problem no one was able to solve
I'm trying to use an ActiveX control (TiffDLL, to manipulate and convert
TIFF images, found on http://www.activex.com) with Perl for Win32.
Usually, I'm able to use OLE with syntax:
use Win32::OLE;
Win32::OLE::CreateObject("ObjectName",$conn);
Trying to use this DLL in the same way:
use Win32::OLE;
Win32::OLE::CreateObject("TiffDLL.ClsTiffDLL",$conn);
$param = "source=c:\\tmp\\tif\\00000001\.tif, dest=c:\\tmp\\img001\.gif,
format=gif";
$result = $conn->ConvertImage($param);
print $result, "\n";
I get a few of error messages windows like this:
Instruction at "0x0f044e3a" referenced memory at "0x01c21dc8". Memory
cannot be 'read'.
then Dr. Watson starts but the application works well!!! It converts my
image.
Suggestion? Ideas? Is ActiveX supported?
Best regards.
Thanks in advance.

i don't know the original question but at least help the poster with
better regex code.
s/(\d\d\d\d)/$1+1000/e
or
s/(\d{4})/$1+1000/e
\d matches a digit and is much easier to read and write than [0-9]
{4} matches 4 previous subexpressions.

I had actually tried that and yes it works fine from the
command line, but as part of a script which is run from
the webserver it causes the server to "hang".

Subject: BETA TESTERS NEEDED!!!
Message-Id: <6drvrc$km$1@nnrp1.dejanews.com>
Hello Everyone:
We are an online business and we have just developed a new server based
program using both CGI and Java.
This program allows a person to automatically setup over 20 features on
his/her account. These features include a Java Chatroom, Search Engine, File
Manager which can be used to upload/delete files to their account and even
change the permissions on files and move between directories, Hits Logger,
Shopping Carts, Error Page, and much more.
Like many programmers, we have spend considerable time working on this
program, but we can only find so many errors.
We are in need of beta testers to try out the program. We are most interested
in feedback! We want to know of any GRAMATICAL (including spelling) errors,
bad interface, and just anything about the program you would change!
This is in no way a soliciation to buy our services, as we do not believe in
spamming the newsgroups. I persoanlly feel that the newsgroups is a good
place to find smart people who would give good feedback if they were to beta
test this program.
If you are interested, please write down the login and password below.
login: test
password: abc
You will need this login and password when entering the site. Visit this site
to try out the program, we hope you like it:
http://www.test.communitech.net:911
Remember we really want your feedback! This is the only way we can improve
our product or make any necessary changes. Please pay attention to the English
and make sure everything makes sence to you. Please send feedback to
webmaster@communitech.net.
Finally, all of the links lined up horizonally at the bottom of every page are
not working yet, other than this, evertying should be working fine. Feel free
to upload files, create a Java Chatroom, create a search engine and search the
website, whatever you want.
Thank you very much for your time and I hope I have captured your interest in
beta testing our program.
Best Regards,
Gabriel Murphy

This appears to be an attempt to do a csh/tcsh command in
perl. Clearly this doesn't work. "set" is not a "UNIX
command", it's a command in a shell to set an internal shell
variable.
You can't do it in perl (unless you re-write tcsh in perl
:-)
Beat to look in the doc. for your shell for how to set
prompts.

Very new to programming web sites (love at first site). Working on a
non-profit project that I want to be a real public service. There are many
features I would like to add from stock scripts, shareware and freeware, but
am only about 50% successfull in getting the scripts running on my Unix
vertual server through tabnet.
Looking for someone with experience and knowledge to share in adapting
existing scripts (I'll try to crawl before I learn to walk). I'm sure I can
find something to offer in the way of mutual exchange (even paid support).
My first web site can be seen at http://michianalaw.com (I just sold this
site yesterday). My non-profit site is at http://michianafaith.com. (I pay,
or donate for all scripts used on my sites - it is money well spent).
Would really like to get DCLinks98 running (sitedeveloper.com) the author,
understandibly like many, does not encourage support. There are some others
I would like to try. Anyone wishing to provide personal assistance would be
greatly appreciated. My questions are too numerous and lengthy to post.
Thanks in advance!

Now you're hooked. Soon you'll be spending your money on books with

you're just adding one... last... feature...

Well, at the risk of being pilloried again (hey, maybe I *like* being
flamed), I'll suggest that your best strategy is twofold:
1) Hire more experienced programmers to get you through your immediate
needs. (Maybe they'll help you learn as they go. I'd be flattered if
one of my clients asked me to explain my code to them.)
2) Purchase the book _Learning Perl_, and see if that doesn't get you
to a point where you're better equipped to answer most of your own
questions by consulting the excellent documentation that accompanies
perl. After _Learning Perl_ comes _Programming Perl_. And at all
times, consult the docs. See especially perlfaq, and perlfaq1-9.
If an answer in the FAQ is unclear, bring it here.
You might also want to visit www.perl.com, where you can read about
training and other ideas for self-tutelage.

Message-Id: <1998Mar7.104903.4026@rumba.m.isar.de>
Hello,
I want to check a string that's entered by the user against some regular
expressions I read from a config-file. Now I am wondering what is the fastest
way to do that:
a) Put the expressions in an array and do something like
foreach $exp(@ARRAY)
{
if($string =~ /$exp/)
.....
b) Generate one regexp in the form exp1|exp2|exp3|exp4|exp5...
and do one match against that.
I don't need to know which of the expressions matched, and they are read in
once during startup.
So what's the fastest way to do this?

I suspect the original questioner wants to keep his RADIUS server
running while the update is going on. The basic Livingston RADIUS
server doesn't use file locks, so it'd blow past the lock above and
possibly access the db in mid-update. Our locally-hacked copy uses a
gdbm database which covers the locking issue, but the above procedure
would unnecessarily lock the server out for the duration of the update
(too long to be acceptable, in our case).
In our case (or for the stock Livingston server) a more viable
strategy is:
Grab an exclusive "I'm modifying file" lock through some
standardized method (e.g. create "file.lock"
and lock that)
Create file.new
Rename file.new -> file
Remove exclusive lock
This will work fine (at least as far as the RADIUS server is concerned)
because the server closes and reopens the file for each
authentication. If it did keep the file open constantly, then one
would have to notify it to close/reopen (if it had the ability) or
kill/restart the server (crude, but effective).
The point is that there's no one right way to update a file that
may be in use. You have to tailor the procedure to match the
other tasks you may be interacting with.

No effect, but what it turned out to be (and I'm not sure why)
was the need to start syslogd with the -r parameter. I found
this info in dejanews, at the suggestion of the robot reply to
new posters to this group. :-)
The robot also mentioned 'use diagnostics' with the perl -w
parameter, but for a while it had me convinced that my perl
package was broken. Try it, perl complains about something
missing and when you look, indeed it is. 5.003_07
#!/usr/bin/perl -w
use diagnostics;
use Sys::Syslog;
$program = "perl";
openlog($program, 'cons,pid', 'LOCAL5');
syslog('info',"this is a test\n");
closelog();
While the syslogd -r works, it causes minor problems for innd and
agetty. If anyone has a better solution, then I'd sure appreciate
hearing it.

"-w flushes out most problems" is a gross overstatement. It does,
however, catch a lot of certain kinds of errors.
As far as comparing oil changes to -w, that one has me scratching

Uh, `/bin/ls`? Surely you mean <*> or glob "*".

-w's tendency to spew hundreds or thousands of lines of messages
is yet another indication it's still not ready for prime time.
Just about every compiler I've ever used has had a message like
"Too many errors. Compilation halted." However, -w has evolved in
the direction of dogma rather than utility. In my humble opinion.

This is how Tom addressed my complaint about what was basically
a slur on my book.
My Foreword is quite clear on Randal's role in the book, and although
I can agree to disagree about many things, I just can't let it lie
when Tom states or even insinuates that there was something amiss
in the process of titling or attributing Effective Perl Programming.
I assure you, *that* process was very carefully executed.

You lose. Big.
In article <34FEEBF7.62846341@5sigma.com> you write:

Message-Id: <null>
Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
