Subject: Bad Return-Path when using Mail::Mailer
Message-Id: <henris-BA262E.15281523072001@uutiset.saunalahti.fi>
I noticed that messages sent over SMTP with Mail::Mailer have a header
like this:
Return-Path: <uid-that-runs-the-script@domain-without-computer-name>
This can be a serious problem if the constructed address is not really
your address--ie. the userid that runs the script is not an ISP userid
belonging to the same user.
I tried adding a header called Return-Path explicitly, but it didn't
work. How can I put my real address in the Return-Path header? Where is
the header generated?

Mason will transparently decode the form parameters for you, GET or POST -
see http://www.masonhq.com Its not the easiest thing in the world to get
set up, but if you are not a sysadmin type I would recommend using the
apache toolbox (http://www.apachetoolbox.com/) to build your
Apache+Mod_Perl - its pretty easy to use. Hope this helps --

Dont mistake programming languages with web-whatever technologies, application
blah servers. Java cant do by itself what you describe above. You need
to use
Java servlets. Thats not a bigger requirement than installing mod_perl together
with some modules to get the requirements you mention above. Data persistency
in a stateless environment has nothing to do with the technology you
use. Its
just one or the other implementations of the same mechanism, be it cookies
or get urls with session ids. Java servlets dont cast some deep magic
layer over
the http protocol in order to achieve data persistency.
And by the way this is a Perl newsgroup. Don't expect anybody to comment on
such a boring interface between two programs as CGI is.

use Cwd;

BTW "cwd" stands for Current Working Directory. Cwd is a standard module

Subject: FAQ: Why doesn't & work the way I want it to?
Message-Id: <YAU67.43$T3.178683392@news.frii.net>
This message is one of several periodic postings to comp.lang.perl.misc
intended to make it easier for perl programmers to find answers to
common questions. The core of this message represents an excerpt
from the documentation provided with every Standard Distribution of
Perl.
+
Why doesn't & work the way I want it to?
The behavior of binary arithmetic operators depends on whether they're
used on numbers or strings. The operators treat a string as a series of
bits and work with that (the string ""3"" is the bit pattern
"00110011"). The operators work with the binary form of a number (the
number "3" is treated as the bit pattern "00000011").
So, saying "11 & 3" performs the "and" operation on numbers (yielding
"1"). Saying ""11" & "3"" performs the "and" operation on strings
(yielding ""1"").
Most problems with "&" and "|" arise because the programmer thinks they
have a number but really it's a string. The rest arise because the
programmer says:
if ("\020\020" & "\101\101") {
# ...
}
but a string consisting of two null bytes (the result of ""\020\020" &
"\101\101"") is not a false value in Perl. You need:
if ( ("\020\020" & "\101\101") !~ /[^\000]/) {
# ...
}

Add the values. Divide by the number of hash entries.
sub sum {
my $sum;
$sum += $_ foreach @_;
return $sum;
}
sub average {
return sum(@_)/@_;
}
my %hash = ( a => 1, b => 2, c => 3, d =>4);
print average(values %hash);
This prints:

Either you are running an old version of Perl, or there are very old
directories with incompatible binaries in @INC - either way, a fresh install
should fix it.

Dunno, could try adding an INC parameter in Makefile.PL. Perhaps its a
compiler issues, have you successfully built other modules? Anyway, hope
this helps..

Use the length function. 'perldoc -f length' for more details.
$a = "hi there";
print length($a), "\n";

Your "template" files are actually perl code. Why don't you just run the

Subject: nested forks - help....
Message-Id: <OF41DF5F54.FBA09438-ON80256A92.00395CF7@tertio.com>
Hi all,
Any help will be much appreciated on the subject.
I am writing an application whereby I would like to fork a few processes,
and in these forked processes, fork additionnal processes without any of
the parent processes to have to wait for their children to finish. It is
something of the form:
foreach $customer (@customers) {
if ($cust_pid = fork) { #in parent
sleep 1;
$SIG{CHLD} = 'IGNORE';
}
if ($cust_pid == 0) { #in child
foreach $router (@routers) {
if ($router_pid = fork) { #in parent
sleep 1;
$SIG{CHLD} = 'IGNORE';
}
if ($router_pid == 0) { #in child
#do something, main application here
exit; #this exits child process at router level
}
}
}
exit; #this exits child process at customer level
}
So basically, what I am trying to do is for each customer in my list of
customers, fork a process, and then for each router owned by that customer,
fork another process and this is where my main application takes place, at
router level. I think what I have here are nested forks.
My probelm is that my application is giving me really strange results when
I have nested forks. Perl seems to be confusing which child belongs to
which parent or something of the kind. The reason I am saying this is
because when I test my code without the forking at customer level, just at
router level, it works perfectly. More over, when I replace $SIG{CHLD}
= 'IGNORE'; with waitpid($cust_pid, 0); at the customer level forking (ie
make the parent process wait for its child process to terminate before
beginning a new one), the code works perfectly as well. I need though to
have all these processes run concurrently and hence I do not want to use
the waitpid($cust_pid, 0); solution.
Any help on possible alternative ways will be VERY appreciated as I am
writing this application for a customer.
Thanks in advance,
Elias.
PS: if you're interested by what kind of application I am writing, it's
basically a polling engine that monitors some remote site routers via an
ISDN link, and the polls are made from central site routers via the cisco
ping mib. In order to do the polling, I am using Net::SNMP module. Just
thought you might want to know.

Thanks for the help guys. I will give it a go.
I also read that the following works, but the backtick method seems to
be a lot simpler.
open (PROG, "command|") or die "Could not open program $!";
@output = <PROG>;
close (PROG) or die "Could not execute program $!";
Also, how do you get the output of wrap to format itself to the width
of the terminal instead of 80 characters. I am using it such:
print wrap(" ", " ", qq{
Text blah de widgets and sprockets
});

Perl doesn't have "single" user mode.
Cheers,

There is a working, but somewhat dated and over complex example on the
perlipc documentation page "perldoc perlipc". If you have some spare cash,
I'd get the "Perl Cookbook" (O'Reilly, Ram on cover) which has lots of solid
networking examples.

It's enough if you want to write an Excel file from scratch. It is not
if you want to use an Excel file as a "template" in which you need to
fill in just a few values. I suspect that this is what the OP has in
mind ("write *some* values into an Excel-Sheet").
Perhaps it can be done in combination with Spreadsheet::ParseExcel? Are
these designed to work together? I fear not... but I don't know.
