Error in the compilation of vpopmail module
Hi, I'm trying to install a module from CPAN, the vpopmail.pm module. I'm running redhat 8.0 + vpopmail 5.2.1. When I run 'make' to compile the makefile created by the makefile.PL script, i receive the following error messages: vpopmail lives in: /var/vpopmail includes: -I/var/vpopmail/include libs: -L/var/vpopmail/lib -lvpopmail defs: Checking if your kit is complete...

dbmopen can't open /etc/aliases.db file
Hi,
I'm triyng to open the /etc/aliases.db file for reading with the dbmopen
function - the result is that I can't open the file for reading, or
something like this. yes, I have permission because I'm root.
My script is:
#!/usr/bin/perl -w
use diagnostics;
dbmopen(%ALIAS,'/etc/aliases',undef) ||
die "No aliases!: $!";
while (($key,$value) = each(%ALIAS)) {
chop($key,$value);
print "$key $value\n";
}
the output error is:
###
Use of uninitialized value in dbmopen at ./zz line 3 (#1)
(W uninitialized) An undefined value was used as if it were already
defined.
It was
interpreted as a "" or a 0, but maybe it was a mistake. To suppress
this
warning assign a defined value to your variables.
Use of uninitialized value in null operation at ./zz line 3 (#1)
Uncaught exception from user code:
No aliases!: Invalid argument at ./zz line 3.
Does someone could explain me why is it happening?
(i'm using perl 5.6.0 and Red Hal linux 7.2)
Thank you,

Re: dbmopen can't open /etc/aliases.db file
Hi Michael, the problem is not with the "undef" value - undef is fine - if
you read the dbmopen's documentation you could see it.
If I choose a value like "0644" the script still doesn't work.
Bellow, is the output of the execution of the same program, but with 0644 in
place of undef:
Uncaught exception from user code:
No aliases!: Invalid argument at ./zz line 3.
I must admit that the errors are shorter but the program still doesn't
work!!
Oh, hell!!!
Thank you for any help,
bnegrao.

Re: dbmopen can't open /etc/aliases.db file
Thank you nkuipers for answering.
I already tried declaring variables with "my", i already checked the path, i
tested the hash with another name - all this doesn't make difference.
To me, it seems that my /etc/aliases.db in written in a format uncompatible
with the dbmopen().
I'm on the 17 chapter of the book "Learning Perl second edition" and I'm
stuck in this problem. (to open the /etc/aliases.db file for reading is an
exercise of the chapter 17).
If somebody there has a server runing Sendmail, you have the aliases.db file
too.
Moreover to simply solve this exercise, i'd like to know it the dbmopen()
really works with my system files.
Thanks for any help,
Bruno.

Re: dbmopen can't open /etc/aliases.db file
Yeah it worked! I simply changed the '/usr/lib/news/history' for
'/etc/aliases' and
the script showed the file contents.
But, why? Why dbmopen didn't work?
thanks,
Bruno.

Re: autoftp
Yes. Exist the Net::FTP module. The following text comes from the Oreilly's
book "Perl in a Nutshell"
16.2 Net::FTP
Net::FTP is used to transfer files from remote hosts. Using Net::FTP, you
can write simple FTP clients that transfer files from remote servers based
on information passed on the command line or from hard-coded variables. Here
is an example of a client that connects to a remote FTP server and gets a
file from the server:
#!/usr/local/bin/perl -w
use Net::FTP;
$hostname = 'remotehost.com';
$username = 'anonymous';
$password = '[EMAIL PROTECTED]';
# Hardcode the directory and filename to get
$home = '/pub';
$filename = 'TESTFILE';
# Open the connection to the host
$ftp = Net::FTP->new($hostname); # construct object
$ftp->login($username, $password); # log in
$ftp->cwd($home),"\n"; # change directory
print $ftp->ls($home),"\n";
# Now get the file and leave
$ftp->get($filename);
$ftp->quit;
FTP clients have also been integrated with most World Wide Web browsers,
using ftp:// in place of http://. When the URL points to a directory, the
browser displays a listing of the directory, where each filename is a link
to that file. When the URL points directly to a file, the remote file is
downloaded.
Here's an example that uses Net::FTP to list files from a remote FTP server
on a web page, with a link from each file to the URL of the file on the
remote site:
#!/usr/local/bin/perl -w
use Net::FTP;
$hostname = 'remotehost.com'; # ftp host
$username = 'anonymous';# username
$password = '[EMAIL PROTECTED]'; # password
$home = '/pub';
$ftp = Net::FTP->new($hostname);# Net::FTP constructor
$ftp->login($username, $password); # log in w/username and password
$pwd = $ftp->pwd; # get current directory
# Now, output HTML page.
print <
Download Files
Current working directory: $pwd
Files to download:
HTML
@entries = $ftp->ls($home); # slurp all entries into an array
foreach (@entries) { # now, output links for all files in the ftp area
# as links
print "\n";
print "ftp://$hostname$_\";>",
"http://www/icons/f.gif\"; border=0>\n";
print " $_\n";
}
print <
HTML
$ftp->quit; # end FTP session
The Net::FTP module implements a subset (as shown earlier in this chapter)
of the FTP protocol as defined in RFC 959. In addition to providing the
methods shown below, the module inherits from Net::Cmd. Some of the Net::FTP
methods return an object derived from the dataconn class (which is in turn
derived from the IO::Socket::INET class), as noted in the entries for those
methods.
The following methods are defined by Net::FTP:
new
abort
appe
append
authorize
ascii
binary
byte
cdup
cwd
delete
dir
ebcdic
get
list
login
ls
mdtm
mkdir
nlst
pasv
pasv_wait
pasv_xfer
pasv_xfer_unique
port
put
put_unique
pwd
quit
quot
rename
retr
rmdir
size
stor
stou

CGI simple but not working
Hi all,
I'm studying the "Learning Perl Second Edition" and I'm learning cgi now.
The book presents a sample cgi that doesn't produces the expected result as
the book says it would.
Could someone test it and say to me if there is something wrong?
The following script was retired from the section 19.6 "Form Generation".
#!/usr/bin/perl -w
# cgi-bin/ice_cream: program to answer *and generate* ice cream
# favorite flavor form (version 3)
use CGI qw(:standard);
my $favorite = param("flavor");
print header, start_html("Hello Ice Cream"), h1("Hello Ice Cream");
if ($favorite) {
print q("Your favorite flavor is $favorite.");
} else {
print hr, start_form; # hr() emits html horizontal rule:
print q("Please select a flavor: ", textfield("flavor","mint"));
print end_form, hr;
}
Thanks for any help,
-

Re: CGI simple but not working - I discovered
Hi all, the problem is that the script is really erroneous. Where you read
"q(..." should be "p( ..."
The p() function is a part of the CGI.pm modules and stands for a new
paragraph.
the right script is:
#!/usr/bin/perl -w
# cgi-bin/ice_cream: program to answer *and generate* ice cream
# favorite flavor form (version 3)
use CGI qw(:standard);
my $favorite = param("flavor");
print header, start_html("Hello Ice Cream"), h1("Hello Ice Cream");
if ($favorite) {
print p("Your favorite flavor is $favorite.");
} else {
print hr, start_form; # hr() emits html horizontal rule:
print p("Please select a flavor: ", textfield("flavor","mint"));
print end_form, hr;
}
Thanks,
bnegrao.

Right. This is the easiest way. But, just to answer him, what he could do
using regular expression could be something like:
foreach (@attt) {
/=/ && ( ($out) = (split (/=/))[1] );
}

Re: Regular expression
RE: Regular expressionHi Javeed.
This code:
foreach (@attt) {
/=/ && ( ($out) = (split (/=/))[1] );
}
stores the string "HELLO" in the variable $out. Then, if you issue print "$out" you
would get a "HELLO".
But when I read your e-mail again I realized that you want to store the entire last
line. So yoy should use this code instead:
foreach (@attt) {
/=/ && ( $out = $_ );
}
The foreach (@attt) starts a loop storing every line of @attt in a default variable
called $_
Then, if the regul. exp "/=/" matches against the default variable $_, the &&
statement is executed, storing the variable $_ in the variable $out.
For clarifying purposes, you could write the same code as:
foreach $line (@att) {
if ($line =~ /=/){
$out = $line ;
print "$out";
}
}
And if you want to get rid of the blank spaces in the last line, add try this:
foreach $line (@attt) {
if ($line =~ /=/){
$out = $line ;
$out =~ s/\s*//;
print "$out";
}
}
I learnt all this from the O'reilly book "Learning Perl second edition".
Tied hugs and warmfull kisses,
Bruno Negrão.

Right. This is the easiest way. But, just to answer him, what he could do
using regular expression could be something like:
foreach (@attt) {
/=/ && ( ($out) = (split (/=/))[1] );
}
