Message-Id: <5o0295$13c_002@interaccess.interaccess.com>
What a couple of weeks this has been...Search - Read - Try - Fail... over and
over and over.
Can somebody please point me to the correct FAQ to get the following
pre-newbie (Yes, that low!) answers to the following questions:
1) How to CORRECTLY install Perl modules on a Windows95 machine;
2) How to get around the installing with the lack of "Makefile" on a
Windows95 machine; and
3) How to compile PROPERLY on a Windows95 machine when you don't have a copy
of Visual Basic or C++ handy.
I suppose everyone but me must have been born knowing this, but every time I
think i have found something it requires something else which cannot be
installed until you have the first item installed.
P.S. Yes, the Perl for Win32 FAQ was one fo the first places I sought and it
didn't help much. No, I'm not asking you to do things I myself have not
already attempted in spades....

Several have mentioned vi and XEmacs already. I myself use XEmacs with heavy
(ab)use of color-based text highlighting. For short jobs, I use vi and/or
elvis. elvis seems to offer some colorizing abilities, though I have not yet
gotten through the docs. Elvis is an enhanced vi clone.

Subject: GD and HTML together
Message-Id: <866343446.13041@dejanews.com>
Hello Perl Folks:
A little background here: I successfuly "printed" the USA map along with
an "X" (to indicate where a person lives on the GIF map) when I put in the
coordinates of X,Y in the program manually. (Using Win32 GD.pm)
Now, here is a problem: I am trying to have the program place an "X" on a
USA map to display where a person live, depending on the X,Y coordinates
selected by the browser -- along with some texts above the image.
However, I get an output displaying the text along with the TEXTS of
the USA image (instead of the PICTURE of USA itself). So I took out
"print &PrintHeader;" and that returns a bad gif file and without the
TEXTS I wrote in HTML. (I hope you all are following me here :-D) After
this paragraph will be a copy of the program I used - and I hope you can
find out how to solve this problem
------------------------------------------
push (@INC, "cgi-bin");
require("cgi-lib.pl");
print &PrintHeader;
&ReadParse(*XY);
print <<"MAPPING";
<html>
<head><title>$XY{xandy} is the value for X,Y</title></head>
<body>
The value for X,Y is: $XY{xandy}
MAPPING
use GD;
$| = 1;
$FileIn1 = "usa.gif" unless ($FileIn1 = $ARGV[0]);
$FileIn2 = "x.gif" unless ($FileIn2 = $ARGV[0]);
$File = "\&STDOUT" unless ($File = $ARGV[1]);
print "Content-type: image/gif\n\n";
open(USA, "< c:\\httpd\\cgi-bin\\temp\\usa.gif") || die;
binmode USA;
$USAmap = newFromGif GD::Image(USA) || die;
close (USA);
open(x, "< c:\\httpd\\cgi-bin\\temp\\x.gif") || die;
binmode x;
$Xspot = newFromGif GD::Image(x) || die;
close (x);
$white = $Xspot->colorClosest(255,255,255);
$Xspot->transparent($white);
$USAmap->copy($Xspot,$XY{xandy},0,0,25,25);
if ($USAmap->gif($File)) {}else{}
if ($Xspot->gif($File)) {}else{}

Perhaps you can perform an nslookup in some way? I'm sure
you could just parse the output to `nslookup $ip_number`, but you may
find a better way of getting it (connect to port XX, etc.).

That didn't work for you? Works for me, although I'd change the while loop
to use $_ as the default, or I'd wrap the conditional in defined(). If
it's still not working for you, could you tell us what version of Perl you
are using? Hope this helps!

I need a script that will launch a page using a combination of a

Yes and no. No, you can't tell if an address is valid just by looking at it.
But something somewhere needs to determine definitively whether an address is
deliverable.
<at a shell prompt>
telnet smtphost.someplace.else.com smtp
<wait for response from remote machine, then tell them who you are>
HELO my.domain.com
<wait for happy response code, then ask for confirmation on an address>
VRFY address@someplace.else.com
<wait for response code; see the appropriate RFCs for response codes>
QUIT
<back ro a shell prompt>
Or just use Net::SMTP
Of course, this may set off alarms at the remote site and the Sendmail book
recommends disabling VRFY as a privacy/security risk (of course, without VRFY,
are you really meeting the SMTP spec anymore?). This method is slow,
unreliable and may annoy some, but it's less bandwidth than bounced mail and
in many cases will tell you precisely what you want to know. In this case, I
wouldn't recommend using it.
<straying further from the topic of perl...>
Then again, a multi-stage process using this method may be the most
responsible, especially if you're processing individual addresses (not some
bulk spam list).
1) Find out if the provided address is in the proper format
1a) Correct common mistakes (clueless@aol syndrome)
1b) Cull out canonically correct but obviously BAD addresses (root,
postmaster, abuse, everyone, president@whitehouse.gov, &c.)
2) Check if the domain will take mail (nslookup, MX records, ...)
3) Check that the address doesn't EXPN (expand) into a gigantic list on the
receiving end.
This last check may be difficult because of the security/privacy concerns that
lead to the disabling of the VRFY command. We're caught in a bind becasue we
don't want to inadvertently spam everyone on a mail alias, on the other hand
we want to protect our systems and users from some poorly-socialized
14-year-old with more ability than ethics.
So, speaking of ethics, netiquette and such, is it considered 'rude' to probe
a remote system at the SMTP level, even if you're trying to avoid spamming
people or bouncing mail? Or is using EXPN or VRFY an invitation to system
administrators everywhere to put a snake in your (real) mailbox?
Sorry for the digression,
Bob

That's true, but VRFY isn't the answer.

I highly, highly doubt that email address exists. But being behind
a firewall doesn't leave me much choice of an smpt server to connect to.
Other example, which of the following addresses is/are valid:
abigail@venus.ic.iaf.nl, jennifer@venus.ic.iaf.nl, pgl@venus.ic.iaf.nl
abigail@mars.ic.iaf.nl, jennifer@mars.ic.iaf.nl, pgl@mars.ic.iaf.nl
abigail@pluto.ic.iaf.nl, jennifer@pluto.ic.iaf.nl, pgl@pluto.ic.iaf.nl
Not to be find out with telnet.

That's reasonable. Even if the address is valid, but your mailer agent
doesn't know what to do with it, it's probably useless anyway. But
a lot of sites have a default address to send mail to; in that case,
it won't help.

But how would you know? And EXPN might show one or two addresses,
but those could be themselves result in a gigantic list. Not
everything is done and sendmail level.
And UUCP isn't giving you EXPN or VRFY.

Well as for the first question of counting the exact number of times
[+=*/%x.]=, **=, <<=, >>=, or = can be solved, I *believe*, by overloading
these operators. (But if you're gonna use it in a serious way, please read
the warning in the Camel.)
Similarly, by overiding 'eval', the second question can be solved too.
Not that I can make them work in short time. There're too many things
to consider (at least for me right now) to write a over(rided|loaded)
funtions. Let me know if you make it. :)

No, perl handles any length just fine.
There *is* a limit to the length of a record that any particular
computer can handle though.
The size of the virtual memory.
: Is there a way to reset that limit?
Yes.
Buy more RAM or increase the swap size ;-)

First, thx so much for your response, Nathan.
One more question though:
How can i explicitly specify using 'sendmail' instead of 'mail'?

Subject: mod_perl or fastcgi install, liberl.so help..
Message-Id: <33A33959.32C1@hotmail.com>
Hi..
I am looking to do a few things, but I'm not sure how much I can do
remotely.
Needless to say, I'm hoping for a little direction in where to tell my
server tech to look, and to do with some things he's having trouble
with.
I'm trying to get either mod_perl or fastcgi to work on this system so I
won't chew up the CPU, etc.. Right now I have a chat site, and it's
getting so much traffic, that it's much too slow, and doing a number on
the machine it's run on.
The chat scripts are in Perl and I want to keep them that way for
portability, etc... so please don't post to me about how I should do
this in C, etc.
Also, I am looking into building a shared libperl.so library to link my
script to. I want to link my main perl binary with this, as I
understand is will make my 500BK+ /usr/bin/perl file run as small as
only 11k to 30K in size! I could really use that feature at this point
as well, or at least untill we get the mod_perl working. But he's having
trouble installing it.
I need to do something, but my access is somewhat limited, because I'm
not the tech at my server, and although I do have root access, I can
only do things remotely via telnet. I think they might get annoyed wth
me going to the server and tweaking the Linux box. So, what exactly can
I do from remote access via Telnet?
Is there anyone that can advise me about how to get the mod_perl going,
and what and *if* I need to change in my scripts usually. I am a plain
perl hacker (not an expert), in other words, I do scripts.. I don't have
knowledge of how everythign workds, let alone, .pm, etc files and mods..
and I surely know very little about the actual Linux box and how to go
about installing a plugin such as mod_perl. I'm looking and learning as
much as I can, but this needs to be done soon, and I would appreciate
any advice, etc.. I hope that I don't have to change much in my scripts,
but I am more concerned with getting this working. My tech hs read
through all the fiels wth information about the mod_perl install, but
yet, he's having trouble wth it. *cringe* For now, I'm stuck. Any ideas,
advice, or pointers? Maybe I need to send him to a mod_perl site for
dummies?. maybe I should look there too :0
BTW, I'm running Linux, with Ret Hat 4, Apache 1.2 (not beta), perl
5.003, Kernel is 2.0.18 .. Thanks for any advice. This is all new to
me, and all the info is vague it seems. Thanks again for any help.

You don't explain the problem(s) you're having with mod_perl.
Configure/build/install usually involves nothing more than:
perl Makefile.PL && make test && make install
The docs explain this and more if you need to link static Perl extensions,
enable additional features, etc.
mod_perl.pod explains how to configure your server:
---
For using mod_perl as a CGI replacement, the recommended configuration is as
follows:
Alias /perl/ /real/path/to/perl-scripts/
<Location /perl>
SetHandler perl-script
PerlHandler Apache::Registry
Options ExecCGI
</Location>
---
You don't need to be "an expert" or know how everything works to use
mod_perl. If you're script doesn't run out-of-the box, read the FAQ. It
explains where CGI lets you get away not cleaning up global variables, etc.,
and how 'use strict' and '-w' will help you a great deal, along with other
tips.

Number 28 is ENOSPC, or no space. Get DB_File or GDBM for unlimited
key/value size.

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.
