That isn't what gethostbyname() returns.
Did you "perldoc -f gethostbyname"?
($name,$aliases,$addrtype,$length,@addrs) = gethost*
To see the IP address(es) you have to unpack the
@addrs, e.g.
my ($name,$aliases,$addrtype,$length,@addrs) =
gethostbyname('ftp.uu.net');
foreach my $a (@addrs) {
my $addr = join('.', unpack('C4', $a));
print "$addr\n";
}

Get the O'Reilly books. You'll want the llama book, the camel book and the CGI
book & you'll be in great shape. Read the llama book first, dip into the camel
book as necessary. The CGI book I don't have, but have heard good things
about... many find that they can get by with the on-line documentation for CGI
stuff (there's some basic info in the llama book to get you started).

You should just get a book, such as "Learning Perl", to teach you Perl,
and then a book to teach you the other skills. For the "web dev" part
of the job, Lincoln Stein's books are good.
Perl is a tool, and "web development" is a task. you are likely to
need other tools than Perl as well, so starting from a non-Perl-centric
prespective is much better (IMO) :)

very strange. hopefully you still pay for the work that you do not
use.
note to the uninitiated: some unscrupulous "designers" will have you
submit work for which they will not pay you so that they can show it
to the client as one of the several samples they promised, but with
minimal financial risk. furthermore, the client might like part of
your work but not others, so the "designer" will incorporate your
nice peices into another person's successful bid, and you lose!
remember that a contract is an obligation to pay. don't provide
your services for free! business is business.

Subject: How do I get Perl Modules to run in my webspace?
Message-Id: <nXAznHAANB32EwtX@dragroup.com>
I am trying to create and access a DBM file in my webspace, and the
script I am using (from a Perl 5 How-To) says I should use the DBM
module by useing the following lines in my script..
use Getopt::Long;
use English;
use DB_File;
I have done this and my ISP tells me to upload these modules to my CGI-
BIN Directory, and this I have done (with the exeption of Getopt - I
didn't have Getopt.pm but I did have Long.pm so I uploaded this instead
and call it with the line 'use Long;' in my script).
However, the script that creates and writes to the DBM file keeps
crashing the moment it encounters the line 'use Long;' or if I comment
this line then it crashes at 'use English;', or if I comment them both
then it crashes at 'use DB_File'.
Any advice on how I can get Perl Modules to run in my webspace would be
most welcome.

I'm fairly sure once a month should be in the FAQ (moderator time
permitting). that way people that DO want to search before posting get
rewarded by already having it handy instead of having to sift through
Deja News (and hope that the last time it was discussed it wasn't by a

This is the kind of thing I'm trying to catch.
my $bad_html = '<TABLE>
<TR>
<TD
Hello
</TD>
</TR>
</TABEL>';
Running that in your program I get:
perl test_html
Parsing $good_html.
Parsing $bad_html.
Done.

I donot want to run the mailprog and read the content of the file in

Browser is able to attach files and keep them seperate. But I need this

you are a bit confused. since you have an init() function in both
classes, but the object is blessed into the derived class, the
object is going to look in the derived class first, even if the
object is used in the base class.
step through your code again keeping this in mind and you'll see

Subject: next in a continue block restarts continue block, but...
Message-Id: <F7z7DM.Fno@unx.sas.com>
If you execute a next in a continue block, it restarts the
continue block. This seems to be the expected behavior.
How do I do something like a next, but _not_ have it restart
in the continue block since I'm already in it?
For example:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
#!/usr/local/bin/perl5 -w
use strict;
while (<DATA>) {
chomp($_);
print "Start of while block\n";
print "End of while block\n";
}
continue {
print "Start of continue block $_\n";
if ($_ eq "data1") {
next; # <<=== replace next with ???
}
print "End of continue block\n";
}
__END__;
data1
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Of course, this will go into an infinite loop in the continue block.
There are lots of not-very-nice ways around this. I could use a
"goto" to jump to the end of the continue block, or I could
rework the "if" logic, or a whole bunch of things that will make
the code much more complex and/or really ugly.
Well, yeah, the code is already complex and perhaps just a little
ugly, but "redo", "next", and "last" keep me from having to do
some really twisted things to keep the logic correct. (Imagine
that "if" in the continue block above buried behind lots of
if's and loops already.
Side note: "redo" will jump back up to the while loop, but "next"
won't. Expected, I know... Just pointing it out.
Just wondering if I overlooked something really simple. Thanx!

Hi,
Is it nmake that is complaining, or perl? There's a couple things
that might be going on:
- the nmake15.exe got corrupted in the download, or wasn't extracted
and installed successfully; does it work on other Makefiles?
- in your perl's Config.pm file, there's a line make=.... indicating
what perl expects your make program to be. Is this set to be nmake?
- did you do 'perl makefile.pl; make', and not 'perl makefile.pl; nmake'?
If you really did use 'make' instead of 'nmake', and didn't
get an error about a "Bad command or file name", then there's a 'make'
program on your system (perhaps from cygwin?). Be sure to say 'nmake'.

and what exactly is your point?
a. you thought I didn't know that?
b. actually, I can't think of another possible point.
in case you're wondering, _my_ point is:
STOP USING A REPRESENTATION THAT IS UNNATURAL AND HARD TO UNDERSTAND
(as evidenced by people getting it wrong) AND JUST SAY THE NINETEEN
HUNDREDS! THE NINETEEN HUNDREDS _are_ A CENTURY. THE YEARS FROM
1000 THROUGH 1999 _are_ A MILLENIUM. THEY'RE JUST NOT ONE THAT FIT
WELL INTO THE UNNATURAL AND HARD TO UNDERSTAND (as evidenced by
people getting it wrong) CENTURY SPLITS.
stop writing functions that return year-1900. stop saying `20th
Century'. stop whining about 2000 not being a change into a new
millennium (because it is, though not one that's on the split between
the 20th Century and the 21st Century).
there. is _my_ point clear?
have you _ever_ seen anyone think 2000 is part of the 1900s?

You mean the host id, which is held in NVRAM, (which can be modified),
which was designed to allow licensing of software, rather than the
tracking of the person who was using it.
The fact is that host id's existed a longtime before the Internet
went "mainstream". Given the current rate of "dumbing down" of
functionality, it is only a matter of time until this "host id"
techology gets misused.

Rochkind has a quote along the lines of `file locking belongs in the
kernel as much as trig functions belong in the kernel'.
the idea was that every set of programs that wants to cooperate with
locking will run another process, an advisory process, that all the
programs in the set will communicate with to decide who has locked what.
and that works fine, as long as your set always includes vi, or always
includes grep, or always includes...

http://www.cpan.org/modules/ and look at the first link titled how to
install modules. Pay attention to the paragraph about using PREFIX.
This is also in the FAQ.

You need to use single-quotes around the string in $MULTI_TAG, or double
the back-slashes so they survive into the regex. \Q would be a disaster
-- you *want* those metacharacters to be interpreted as such.

Thanks, that did the trick. I did try to use autoflush, but that was getting too compliccated for
what should have been a simple script.

because they're ambiguous, and ambiguous in a small time frame. a real,
practicaly one that affects us (as opposed to the y10k problem, which
is `real' but also `real silly').

actually, for the overwhelming majority of cases (AD1-AD9999), they do.
if used consistently, if there hadn't been `year-1900' silliness, if
data storage would have allowed them, if output fields were wide enough,
there wouldn't have been a y2k concern.
or are you just saying `it would be less convenient'? well, duh.
