Does anyone know if the Activestate can be installed silently.
Additionally can modules be installed silently.
I want to install the perl compiler on remote machines and I also want
to install the libnet module.
Ideally if I could tie everything up in a nice self extracting install
script then that would be pretty cool.
Anybody have any advice/pointers

If you can use the database from Perl, you can use it from a CGI program
written in Perl, in general. If you're not sure how to access the
database, check CPAN for a module which will help. If you're not sure how
to write programs which implement the CGI protocol, check the CGI module.

In addition to the above reply, you might also need to have set on the
server the 'run scripts' option for the dir the script is in. This is what
tells the server to run the script not download it. The associations from
the above reply are also needed.

It sounds as if you want to find out about how a protocol works. Probably
CGI or HTTP. The docs, FAQs, and newsgroups about those protocols should
be helpful. Good luck!

What viewer? What window? What screen? :-) If you're needing to
interrogate a remote device, such as a browser, you should check with the
docs, FAQs, and newsgroups about browsers and the protocols used with
them.

Sorry, but you'll need MIME to handle attachments in any sort
of clean way. The easiest way to do this is to grab the
MIME::Lite module, which has really nice examples in its docs
too. If you're doing this on NT, get ActiveState's MIME-Lite
ppd from their site. If you're doing this on unix, go to
CPAN and get the module there.

I think that's not what you want. Here's a better way:
use Oraperl; # :-)
If you really need it, here's another way.
{
# Print extra info upon failure
my $success;
END {
print "Error occurred when loading Oraperl via perl $]\n"

use Oraperl;

$success = 1; # get here only upon success

Hi
I got me self a little problem here I was hoping maybe somebody
could help me out with. I've been writing some CGI using perl to put
together a online ordering system, and I've hit a snag. My Web server is
NT 4.0 running IIS 40, when running netscape 4.03 as my browser
everything works. The pages run displayed right in the windows that's
generated by the CGI. But when running ie4 as my browser when displaying
a page from the perl all the HTML is messed up. I extracted all the html
and opened in it ie4 as just a html file and it looks great. ??? I don't
understand this at all.

Yes. (I'm not speaking just for myself here, you understand. I have good
reason to believe that those "at the very top" are well aware of both the
positive and negative consequences of this development.)

It's good to know that you and others are ready to throw yourself upon a
grenade, if need be, for the good of Perl.
Speaking only for myself, I'd say that you can restrain from heroic
measures for the time being. I'm taking my cue from Larry Wall, who thus
far has neither hung lanterns in the bell-tower of his church nor ridden
a horse to Lexington while issuing a call to arms. As Larry is a very good
communicator, I'm certain that when he has something to say, he will find
a good way to say it.
There's been some discussion about this in this newsgroup already; see
your favorite Usenet archive for details.
Cheers!

probably.

Start with a smaller project. It's not that you can't do this, but you can
do a small project and a related large one faster than the large one
alone, in this case. It'll be too painful a learning experience to try to
do this program when you say you're "no programmer".
Try first making a program which merely makes a page with links to the
other pages in the directory. (Check it with one of the HTML checkers to
ensure that it's valid HTML, too.) Then, when you've got that working, fix
it so that the link text for each page is the TITLE from the page. (Parse
the HTML with HTML::Parser.) That will be a challenging start right there.
Good luck with your project!

Basic mathematics.
Either using the definitions of even and odd:
print "$n is odd\n" if $n % 2;
Or (not so good, IMO), using the binary representation of a number:
print "$n is odd\n" if $n & 1;

I even tried it in Nyetscape, so I wouldn't have to risk a typo

So do 1e6 other worthy causes. What makes yours more important than all of

Ah, you want to learn about CGI programming. You should check the docs,
FAQs, and newsgroups about CGI programming.
> If you think you can help please e-mail us.
Just to be sure, are you asking for free labor? That's not what this
newsgroup is all about. Even if you were building a website that would
save millions of handicapped baby seals of color who are suffering from
AIDS, neglect, and post-nasal drip because their ship was struck by an
iceberg in war-torn Kosovo, this newsgroup isn't really the place to ask
for volunteers. (A better way would be to search out volunteer
organizations through your favorite search engine.)
Even though I personally can't summon much enthusiasm for your cause, I
nevertheless wish you well in your quest. Cheers!

Boundary bug. That regex should be "[?(.+)]\n" so that the leading '['
on the very first record (which won't have been chomp()'d off) isn't
taken as part of the section name.

Message-Id: <929058653.22371@www.remarq.com>
Does it mean that there's no way to run unix commands or
programs on unix from NT???
I am very surprised at that..if that's true.
Are we talking about deeply involved RPCs? Are there any
simple interface for that?
I have about 30,000 files, and I know Unix will be able to
handle it very well compared to NT.
How about running a telnet or rlogin ( I will need to know
how to do it though).
Just like uux (unix to unix) are there any command in NT as
ntu ( nt to unix)?
Or when I run the CGI perl-script on unix, it can span
another shell which will call the unix interpreter for the
commands instead of cmd.exe of NT?
Any hint will be useful
Thanks..

You can't.
Having a mapped drive is much different than being able to
run processes on that particular machine. Your NT webserver receives
a request for a particular CGI which happens to reside on a mapped
drive. It sees that the CGI is a Perl file and runs your local NT
Perl interpreter against the file. Try compiling a native C program
on the Unix side and then running in on your NT machine via the mapped
drive. It will fail since NT will try to run the program, not Unix.
If you have your CGI directory on a Unix machine, why not put your web
server there as well? Your performance will be much better.
Also, why open a pipe to 'date' and suffer portability problems when
Perl already supplies 'localtime' for you? 'localtime' will work the
same way on Unix *and* NT.

Currently I cannot run web server on that UNIX machine,
also the perticular command that I am looking for
is "gunzip". In future, I may look for some other commands.
language.perl.com/ppt doesn't have gunzip.

As a joke. I thought Tim was quite specifically making a joke
about issues commonly seen with free-server-web-hosting places.
Granted, people in this ng do often take the opportunity to
stick the needle in a bit. Not just to new posters either,
if you take a look at past postings by me, Randal, Uri, Larry
Rosler, ... It's sort of a part of the Perl culture that
programming should be fun, and things should be fun with
good programming tools, instead of the way things run Elsewhere.

A lot of the hardcore programmers in this ng do sometimes
forget that the reason people are asking questions is that
the posters *are* new at this. But still, it is not
unreasonable to ask people to 'do their homework before
coming to class', i.e. check the FAQ and follow the frequently-
posted guidelines.

Oh yeah. We see that a *lot* here. People drop by and say:
"Oh, this is probably a FAQ, but I couldn't be bothered to
look, but don't flame me, and when you write the code add
enough error checking, and email it to me because I never
read this group since you're all such a bunch of a$$holes."
It really makes people ready to help the next several posters
with their problems.

That's why people are always looking for better web hosts.
Unfortunately. It's also why some of us here try to be helpful
when people ask questions that *obviously* belong in c.i.w.a.g.
or one of the server newsgroups, or even one of the java/
javascript/VB/Tcl newsgroups. Like today, for example.
Granted, not everyone manages to be Miss Sociability on this.
A lot of the long-time Usenetters remember how nice life was
before September 1993 and AOhelL, when it was feasible to
explain usenet and Nettiquette to each newbie who committed
an offense. But:
> tell, how can a newbie tell whether the problem is in the Perl code or Server
> related, or even a particular interpretation of the Perl code on that server?
That's the crux of the biscuit. Many don't know there *is* a
difference between HTML and CGI and Perl. Which is why there
is so much in perlfaq9 that is in fact off-topic. Those are
questions and answers there to help others. And some of us
*do* try to be [reasonably] polite and helpful, even if that
help encourages someone to learn how to look up answers, rather
than spoon-feeding them one answer so they have to come back
here for answers #2, 3, 4, 5, ..., 77, ...
In some cases, there is no way of telling what the problem is
without seeing the offending piece of the code, plus server
and software info. And if the experts require that, then
all a newbie can do is trust that the experts know how to do
this, and follow their guidance.. which includes following
the guidelines for this newsgroup.
If I haven't argued this into enough circularity, let me
know. I'll be a_round. :-)

OK, since I am in quiz mode today, can someone come up
with a shorter program that prints itself without opening
any files, spawning processes etc. than this one-liner:
printf($x,39,$x='printf($x,39,$x=%c%s%c,39);',39);

My daemonization and sighup handler are straight out of the perl
cookbook with insignificant modifications (e.g., exec($SELF) instead of
exec($SELF,@ARGS)).
I've actually come up with a better diagnosis of what's going on: The
sighup works the first time, but the second time it doesn't respond to
any signal but kill -9 (and yes, I'm using the correct pid).
