Believe it or not, I had this trouble, and the solution was wierd. If you make
the script on an NT/Win95 box, and then ftp it to linux/unix, you need to make
sure that you are either saving the file as a unix file, or ftp'ing it in
ASCII. This fixed the problem.

Damn, you're right - I guess it was just a mental block after all, the error

Sure it's actually a core from perl? Use the command "file

you'll have to post lots more info regarding the
circumstances that cause this problem.
If not, then there's something else going on.

well, not all classes necessarily need Exporter. a class needs it

Either your book is wrong or you're misunderstanding the difference between
objects and modules.
If you're writing a Perl object (defining a 'new' method, calling 'bless' on
an anonymous hash - those sort of things are the clues) then you don't need
to export any methods as they're always called thru the object interface
(i.e. Object->method). If you're jsut bundling a group of useful functions
together in a module then they'll need to be exported into the callers
namespace.

I presume by "Linus v5" you mean RedHat Linux 5.0 (or 5.1). They both
include perl 5 (not perl 4), so you don't need to install anything else. To
learn perl, get "Learning Perl", (the so-called "llama book") by Randal L.
Schwartz and Tom Christiansen (two of the most brilliant perl hackers, and
frequent contributors to this group). It is published by O'Reilly &
Associates and is ISBN 1-56592-284-0.
Read, experiment and enjoy. "For dummies" books may not help you, as perl is
primarily a tool for smart folks. ;->
For a general linux book, I would heartily recommend "Running Linux" (also
published by O'Reilly and Associates). I don't have my copy here, or I'd
credit the author. RedHat comes with a full set of HowTos and manpages,
however. Open up netscape and follow the links on the default homepage.
Once you get started at perl, you will buy the infamous blue camel book
("Programming Perl" by Larry Wall, Randal Schwartz and Tom Christiansen). You
will have no choice. By that stage your free will will have drained away, you
will be telling your friends how cool perl is and thinking up perl regexs in
your sleep. You have been warned...

Yayyyy! Linus has been upgraded to version 5 :-) (I know it was a typo,
but it was amusing).

Ok, I'm guessing that you just installed the new RedHat and need some
help. It's hard to do much without a more specific question, but the
first thing that I'd recommend you do is start reading the contents
of /usr/doc. There's a lot there, but after you finally make it
through you should have made it past most of the initial learning
curve.
For newsreading and perl, specifically, try man trn and man perl
from your command prompt. I'd also recommend picking up a copy
of `Running Linux' as well as a copy of `Learning Perl'.
You have a fairly steep learning curve ahead of you, but it will
be worth it after you make it through.
Good luck.

You put passwords in a program!? Hello? Didn't anyone ever tell you
never to do that? If you're going to do that, just shoot yourself

Whoops !!! password in plain text !!!!
compiling the perl script would be no help as the password would still be
readable
using strings for instance !
I'm afraid the inclusion of the password is the mistake, tell the group what
you are really trying to
do and I'm sure they'll help

Not true. You got very reasonable answer, saying that if your only
reason for compiling scripts is hiding a plaintext password in the
binary (on Un*x, we have strings command), do not do that. The
underlying reason is that if you are going to do this kind of
things, the newsgroup doesn't have much initiative to help you with
rather advanced topic like compiling. Sorry, but it looks like
waste of time and efford on both our and your side.

- - Give up now.... There is no way to "protect" a password
embedded in a program. Security through obscurity just doesn't
work. If the data is that important, use a real security model.
If you can't justify the cost, then your data is not that important.
- - The perl compiler won't help you in this situation, all the data
items are available in the executable.
strings executable
will show all the constant strings in program. You can play games
with building the password dynamically, but then I can simply run
trace on the resulting executable and watch the I/O.
- - The only way a password can safely be "imbedded" in a program is
to not allow the user read access to the executable file. There
are two common ways to do this.
1. Make the executable setuid and put the password in a file readable
only by the setuid.
2. Provide the program via some kind of network interface. (i.e.
captured accounts, cgi scripts) You need to use some other
authentication system in order for this to work correctly.
- - Both these solutions can be defeated by the sufficiently motivated.

Perhaps 'perl -de 0' is something like what you want?

Take a look at the threads 'PERL environment/shell execution?' and

and also got polite responses.

You mean like my father, when I did something dunderheaded? no, I didn't

Something you seem to have a problem grasping.

Then they should learn how first, don't you think? I mean before jumping

not care if their slip-shod programming practices (because they don't
know any better, and haven't seen the CGI Security FAQ) may compromise
your web server's security?

I saw alot of read the man pages and documentation for answers, I hope I don't get flamed for actually answering
your question. It's the year minus 1900...
$year = $year + 1900;
Have a nice day...

I'll lay 2 to 1 odds that your problem is that you aren't removing the new

from the form doesn't end in a new line therefore they don't match.

Subject: Special: Digest Administrivia (Last modified: 12 Mar 98)
Message-Id: <null>
Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
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.
