Setting up CGI with IIS
Hi,
I am trying to get an example working to get me started but all I get is a
message:
CGI Timeout
The specified CGI application exceeded the allowed time for processing. The
server has deleted the process.
I am working with IIS on NT.
I have installed perl and configured IIS to associate .pl and .cgi with the
perl executable.
I have also given permissions to the user IIS is running as to the cgi file.
The file is:
#!h:\perl\bin\perl.exe
use CGI ':standard';
print header();
print start_html();
for $i (param()) {
print b, $i, /b: , param($i), br\n;
}
print end_html();
Please help.
Thx, Emma.

Search and replace a block of imported text
Hi all, I should be able to do this, but I'm having no success and it's driving me up the wall. I've got a text file made up of ascii and HTML code that I'm dumping into an array in a Perl script. I want to be able to take a specified chunk of this text from the middle of the file between HTML and /HTML (over a number of lines) and simply obliterate it, before reading the array line by line using $_.

Re: Nested hash
Actually, because you are using hash references, you need to use
something like '%{$repeats{$k1}}' rather than '%repeats{$k1}':
foreach $k1 (keys %repeats){
foreach $k2 (keys %{$repeats{$k1}}) {
foreach $k3( keys %{$repeats{$k1}{$k2}}){
if ($repeats{$k1}{$k2}{$k3} == 1){
print I got it\n;
}
}
}

Hi!!
I have a CGI that updated a mysql database, I have a nested hash
structure in it.
something like
$repeats{$solID[i]}{$expId[i]}{$elemenet[$i]}=1
If I am to check this hash is the inner loop written as
foreach $k1 (keys %repeats){
foreach $k2 (keys %repeats{$k1}) {
foreach $k3( keys %repeats{$k1}{$k2}){
if ($repeats{$k1}{$k2}{$k3}
==1){
print I got it\n;
}
}
}
}
Is this correct ??

any idea to solve this problem?
I wrote a very simple cgi to change an IP address of a linux server.
First, user will get LOGIN.PL
LOGIN.PL will call EDIT_IP.PL
if user click 'Save', EDIT_IP.PL will call SAVE_CONFIG.PL
SAVE_CONFIG.PL will do these :
- modifying ip address configuration (/etc/sysconfig/...)
- calling external program (written in C) to restart network card (ifup/ifdown)
- Displaying message configuration saved
- REDIRECTING back to LOGIN.PL
The situation is, all steps are working fine ... except the last 2 steps (displaying
message and
redirecting). Sometimes it works, sometimes NOT ... I dont know why.
Here is the last code of SAVE_CONFIG.PL :
if ($a ne $b) {
Write_ifcfg (eth0, $NewIPAddress);
$ip_addr = $NewIPAddress;
}
Ok Configuration saved.;
system(/var/www/cgi-bin/changeip);
Can I flush cgi operation?
Because after calling changeip, the IP address of the web server will be changed ...
and the
user browser SOMETIMES did not get the output of Ok function.
Here is the Ok function :
sub Ok {
my ($msg) = @_;
print $cgi-start_html(-head=meta({-http_equiv = 'Refresh',
-content = '10; url=http://'.$ip_addr.'/'}));
print BRBRBRBRBRBRBRBRBRBR;
print TABLE border='0' width=500 align=center bgcolor=#C7D7F3;
print TRTH align=center bgcolor=#1E4691font color=#FF nbsp /font;
print TRTHnbsp;
print TRTH align=center$msg;
print TRTHnbsp;
print $cgi-end_html;
}
In the user browser, it will 'stuck' (in progress) ... but if you view source, it
will contain
the content of that Ok web page. Then we need to press browser STOP button, the
message will be
displayed, and the rest is normal ... the redirection (Refresh) is executed.
I was wondering if I can 'flush' the cgi operation, so in SAVE_CONFIG.PL will be like
this :
if ($a ne $b) {
Write_ifcfg (eth0, $NewIPAddress);
$ip_addr = $NewIPAddress;
}
Ok Configuration saved.;
flush_cgi_operation;
# so, cgi output is written in the user browser
system(/var/www/cgi-bin/changeip);
I hope you understand what I meant :) I am not very good in english.
Regards,
me.

Re: CPAN module install error... can you guys help?
The script should work, but when building the module I believe you will need access to the header files, etc. and possibly even when running it, as the make process is trying to compile SSLeay.c file to use as part of the SSLeay.xs module component. So your script will work, but you won't be able to build the module without the devel package. Which if my understanding is correct you have two options: 1) Download the source for openssl and set the corresponding shell variables (not sure what all you need, LD_LIBRARY_PATH, etc.) so that the make process can find your version of openssl (in your home directory, for instance) or... 2) Build the module on a separate machine, preferably running the same compiler versions, openssl versions, etc. and then upload the module to the server and do a *ton* of testing to see if it still works in all its glory. http://danconia.org (p.s. make sure to group reply so the list can help too) james lundeen wrote: I'm on an OLM server.

Instead of a regular expression you can use the transliteration operator
to count characters.

Installed Modules don't run Properly
Hello All! I have searched Google, but it turned up nothing useful on this, so I figured that this would be a good place to ask next. I just installed the DBD::mysql through the Debian package manager, but it doesn't seem to bode well with the compiled version of Perl I installed on the machine . . . ;o| Here is the error that gets returned when trying to run the module : perl: relocation error: /usr/lib/perl5/auto/DBD/mysql/mysql.so: undefined symbol: perl_get_sv Any thoughts? thanks in advance! scott -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Mail::POP3Client errors, not working
Ok, this is very frustrating, 2 days and many hours worth! I have used this
module/lib (libwww) before with ease. The only thing i can think of is i could
be my linux distro? (Debian Woody 3.0), or the pop-servers encrytion methods?.
The following is the exact script i am trying to run, (except with my
personal info removed) and below is the Debugging info i'm getting.
All my supplied data is correct, (i.e. username and password, i use the exact
same info for ~/.fetchmailrc and it works fine. I am including a Microsoft
pop-server and a 'unknown' although probably some form of *NIX server.
I was also reciveing some MD5.pm error's although they seem be gone.
I would appreciate any info, guidance or help anyone could provide.
thank you.

glob subtlety question
Is there a better way to say:
my @input_files = glob (join , @ARGV) unless $#ARGV = -1;
foreach my $doc ( @input_files ) { ... __code goes here___ }
I put the unless clause in there because otherwise...
if there are no file arguments, @input_files ends up having an element [0]
And the foreach loop tries to run anyway.

Re: Net::SFTP causes script to exit if connection can't be made
Zentara is right about what you need to do, but a fuller explanation
of the solution would have been:
Net::SFTP is throwing an exception when it cannot make the
connection. If the exception is not caught, it will cause your
program to exit. The way you catch exceptions in Perl is to wrap the
code that throws them in an eval block. After the eval block, the
exception will be stuffed into the $@ variable, so you can examine
that variable to see if there is some kind of useful information there
about what the exact problem was.

As I mentioned, I need to be able to trap this error and continue

Wrap it in an eval statement.

However, I'm not really sure that that's what you want either. As
written, this line will join three elements into a string and assign
it to $env_findal[$i]. The three elements it will join are:
$fields[1]
$fields[2]
@temp_str - 1
The problem is that last one...I suspect that you want it to be the
last element of @temp_str, but what it is actually going to be is
the number that you get by subtracting 1 from the number of elements

array iteration references
Hi all,
I want to iteract through a array with a step = 2.
Meaning, that, with a array of (1,2,3,4,5,6,7,8,9,0) I want to have 5
interactions with 2elements available in each one. (1,2), (3,4), etc.
Not knowing if there is something OOTB within perl, I just:
sub optionsInitialize{
my ($ref)=@_;
Logit(ref is $ref, size is $#{$ref});
return [$ref,0, $#{$ref}+1]+1;
}
sub optionsNextItem{
my ($ref)=@_;
my @ref_arr=@{$ref};
my $count=$ref_arr[1];
my $max=$ref_arr[2];
my @arr=@{$ref_arr[0]};
$count+=2;
return undef if ($count$max);
$ref_arr[1]=$count;
return ($arr[$count],$arr[$count+1]);
}
sub optionsIsEnd{
my ($ref)=@_;
my @ref_arr=@{$ref};
my $count=$ref_arr[1];
my $max=$ref_arr[2];
return ($count = $max);
}
And I would do something like:
my $parameters=[par1, [sjsj,djdj], par2, [fjkdj,dkdj];
my $options=optionsInitialize($parameters);
while(!optionsIsEnd($options)){
($key, $default)=optionsNextItem($options);
..
}
Now, the two questions:
1 - Is there a better (working) way to do this ?
2 - Thinking of other languages, I thought (my first error I know :P )
that passing a reference to a array would allow me to change the array
inside a sub. But $count is always 0 inside optionsNextItem();
Thanks in advance,

couple questions about refs
hello again,
all my c instincts tell me i shouldn't write a function like this:
sub myfunc(){
my $aref = [];
if ( some_cond ){
return undef;
}
else{
#populate @{$aref}
return $aref;
}
}
but its cool, right?
i know what i really should do is this:
sub myfunc(){
my @array;
if ( some_cond ){
return undef;
}
else{
#populate @array
return [ @array ];
}
}
anyways, second question: how do i create/invoke a function ref?
i wanna do something like this:
sub myfunc(){
#blah blah
}
my $fref = \myfunc(); # is this right?
{$fref}($arg1, $arg2); #is this right? are there any shortcuts like
$fref-($arg1, $arg2)? i know this is the syntax for invoking a method, but
i don't wanna go thru the hassle of making a class
thanks for the tips,

Matching and Filling Arrays
I have a dummy list:
Dog, A, B, C
Dog, 1, 2, 3
Cat, A, 2, 3
I have a unique list of the first record, Dog and
Cat...I want to look through the unique list, and then
match all the records from the main list (as
above)-matching the unique list value (Dog/Cat) with
the main list...then if there are duplicate matches,
as above, fill the array will the info...
e.g. Dog array will contain A,B,C,1,2,3 and Cat will
contain A,2,3...the following subroutine isn't
working...I know the list will be x cols wide, so I
can parse the final array quite easily...I'm dumping
the values into a hash with the unique list name as
the key...so I can take each key...and have the array
as it's data...then parse it...why doesn't the
following code work???
cheers

foreach $arb ( @uniqueroadname )

Re: Uploading files
Yes You can.
1st part
print form method=post name=forandre;
print input type=file name=filetoupload;
print input type=submit name=save value=Save;
print /form;
select file from local machine using file field.
field name is filetoupload.
afeter submiting you get value of file field at server side using
$filename=$q-param(filetoupload);
if(!open(OUTFILE, $SAVE_DIRECTORY$Filename))
{
print Can't open the file;
}
binmode(OUTFILE);
while ($Bytes = read($filename,$Buffer,1024))
{$BytesRead += $Bytes;
print OUTFILE $Buffer;

printing $BytesRead you get size of uploaded file

the first script sets a cookie, but I cant retrieve them when running

Re: Spreadsheet::ParseExcel date problem (year is being reformatted)
If I use $osheetCR-{Val} the value is in incremental serial numbers
from 1 jan 1900 (or 1 jan 1904 for Apple users).
Example: 12-1-1946 is 16814
I can convert 16814 back to the real date with the date::calc but there
must be some way to extract the year in the right format ( and not yy).

Subject: Spreadsheet::ParseExcel date problem (year is being

When I read an Excel file in, ParseExcel reformates the year to
dd-mm-*yy* (for example 10 dec 2002 is 10-12-*02*).
I don't want this to happen, the format should stay the way it was
dd-mm-** (10-12-*2002*).
Here is the code:
use Spreadsheet::ParseExcel;
# Spread-ParseExcel [0.26]
my $oExcel = new Spreadsheet::ParseExcel;
my $oBook = $oExcel-Parse('mail/file.xls');
my($iRow, $iColom, $oWorkSheet, $oSheetCR);
my $iSheet=0;
my @string;
$oWorkSheet = $oBook-{Worksheet}[$iSheet];
for (my $iRow = $oWorkSheet-{MinRow}; defined
$oWorkSheet-{MaxRow}
$iRow = $oWorkSheet-{MaxRow} ; $iRow++){
for(my $iColom = $oWorkSheet-{MinCol} ; defined
$oWorkSheet-{MaxCol} $iColom = $oWorkSheet-{MaxCol} ;
$iColom++) {

PHP is a good templating language, similar to ASP, JSP, etc. The problem with templating languages is that they're too good. It's always tempting for the programmer to introduce yet another small piece of logic into a page. It extremely difficult with these templating languages to abstract the various layers of a moderately complex application. Many applications can be split into three layers (model, view, and controller). The model is the underlying structure of your data, which won't differ whether you're accessing the data through the web, the command line, or a GUI. The view is a thin skin which presents the model on a particular platform (HTML, text, Tk, etc.). The controller validates user input, and decides what happens next. Templating languages are excellent for building the view layer Using mod_perl and template toolkit, or servlets and JSP, or COM and ASP, it's easy to write applications with clear boundaries between layers. With only the templating language, the model and controller are forced into the view layer, which soon becomes unmaintainable.

Subject: getting defunct message
hello people,
When I'm trying to server which listens on
tcp port and
forking child process i'm getting lot of defunct process when
the server
gets lots of requests . Can any body explains why this happens in
general ?
When a child process terminates, the OS releases all the resources used by
the process, but keeps the process entry in the process table. This is so
the parent can read the child's exit status (this is called reaping).
Processes that have terminated, but whose exit status has not yet been
reaped are defuct or zombies.
Two basic ways to handle this:
1. Catch SIGCHLD and call wait() from the signal handler to reap the exit
status.
2. set $SIG{CHLD} = 'IGNORE' in the parent before forking. This tells the OS
you don't care about the child exit status and it doesn't need to hold on to
the process table entry. (Note: this does not work on all systems.)
(The defunct/zombies will also go away when the parent terminates)

Re: couple questions about refs

hello again,
all my c instincts tell me i shouldn't write a function like this: sub

}
else {
#populate @{$aref}
return $aref;
}
}
but its cool, right?
Yes this is fine in Perl. Perl simply does the right thing :-)
i know what i really should do is this:
sub myfunc() {
my @array;
if ( some_cond ) {
return undef;
}
else {
#populate @array
return [ @array ];
}
}
Well ... I would use
return \@array;
it's a bit more Perlish and actually I expect it to be quicker.
(Benchmarking is left to the reader)
anyways, second question: how do i create/invoke a function ref?
i wanna do something like this:
sub myfunc() {
#blah blah
}
my $fref = \myfunc(); # is this right?
without the ():
my $fref = \myfunc;
{$fref}($arg1, $arg2); #is this right? are there any shortcuts like
$fref-($arg1, $arg2)? i know this is the syntax for invoking a
method, but i don't wanna go thru the hassle of making a class
Both these syntaxes are OK. No need for any classes or whatever.

Re: couple questions about refs
Chris, I'll take a stab at this to see if my understanding of Perl is correct. Your first subroutine is acceptable under Perl, but it wouldn't be under C++. The reason is that Perl has automatic reference counting and garbage collection. Perl counts the number of references there are to data elements. When you create $aref, the reference count of the anonymous array is set to 1. When the subroutine ends and you would expect the array to disappear, Perl checks the array's reference count. Since the reference count is 1, the array is kept in memory. If the variable into which the reference is stored in the calling program goes out of scope, the reference count on the array will go to zero, and Perl will be free to release the array whenever it wants to, but I think I read that you can't influence the moment when the array will actually go away.

Subject: glob subtlety question
Is there a better way to say:
my @input_files = glob (join , @ARGV) unless $#ARGV = -1;
foreach my $doc ( @input_files ) { ... __code goes here___ }
I put the unless clause in there because otherwise...
if there are no file arguments, @input_files ends up having
an element [0]
And the foreach loop tries to run anyway.
Right, so you still need the unless clause. I prefer to write it as:
unless @ARGV
Also, the join can be simplified to
@ARGV(see perldoc perlvar, search for the $ variable)
So that would be:
my @input_files = glob @ARGV unless @ARGV;
But, if your running under a UNIX shell, the arg list has already been
globbed, no? Are you running under Win32?

The [\d\,]* matches 19,466, but then \s+ can't match because the next

Re: get COOKIES with 'HTTP_COOKIE' ??
what am I doing wrong with these co-operating perl-scripts?
the first script sets a cookie, but I cant retrieve them when running
the 2nd..
Something wrong with the $cookies=$ENV{'HTTP_COOKIE'};
$cookies=$ENV{'HTTP_COOKIE'};
if ($cookies=~/name=/){
...
}
else {
print it doesnt exist any cookie!;
}
Erik, I think your problem is not that HTTP_COOKIE isn't being set,
but that the format isn't what you are expecting. You are testing to see if
cookies contains 'name=' and if that fails, just assuming that HTTP_COOKIE
is empty. Did you try simply printing HTTP_COOKIE to see what value it
actually has?
I don't believe cookies are returned to the server as 'name=erik'
and 'value=test_cookie', but rather as 'erik=test_cookie'. So you should be
testing:
if ($cookies =~ /erik=/) {

When you use the double quotes: $arg looks like foo (bar) But when you use single quotes, there is no expansion just what you enter is what you get, so the $arg looks like foo \(bar\) Obviously the second is not what you want.

Unlike split, join() takes a string as its first argument, not a regex.
What you want is this:
$env_final[$i] = join (,,$fields[1],$fields[2],@temp_str -
1);

Notice--no '/'s here
However, I'm not really sure that that's what you want either. As
written, this line will join three elements into a string and assign
it to $env_findal[$i]. The three elements it will join are:
$fields[1]
$fields[2]
@temp_str - 1
The problem is that last one...I suspect that you want it to be the
last element of @temp_str, but what it is actually going to be is
the number that you get by subtracting 1 from the number of elements
in @temp_str. Try this instead:
$env_final[$i] = join(,,$fields[1],$fields[2],$temp_str[-1]);

NET::SMTP sometimes loses From: line
Hello, I have a perl program that sends out mail. It has been in production since 1998. It works fine in most installations. I recently changed ISPs (new: ISP outgoing mail server is mail.megapath.net) The messages are now losing the From: line. In the expanded header, the Return-Path: line is fine. This occurs on Solaris, Perl 5.005 and RedHat 7.2, Perl 5.6.1. The problem goes away when I change the outgoing mail server to my internal SMTP server. (An Internet appliance). I guess the right answer is to run my own SMTP server. Do not want to do that since I do not know much about SMTP. Is there any way to get NET::SMTP to work with the ISPs like mail.megapath.net?

Where did this come from?
{
${env_desc[$i]} = join (',',${env_files[$i]},${env_start[$i]},
${env_end[$i]}, ${env_bytes[$i]}, ${env_errors[$i]}, \n);
}
my @fields;
my @clm_types = qw ( PHC.ZIP PMC.ZIP );
Again, why not just create a regular expression?
my $clm_types = qr/P[HM]C.ZIP/;
for ($i = 0; $i @clm_types; $i++)
{
@temp_str = grep (/${clm_types[$i]}/,@env_desc);
@fields = split (/,/,$temp_str[@temp_str - 1],4);
$env_final[$i] = join (',',$fields[1],$fields[2],@temp_str - 1);
}
} # End of the procModemLog()

Re: Getting a variable back

I have a program that gets an EXE file using a regex pattern and puts it

I then download the matching file:
if(scalar(@match)) {
$file=$match[$#match];
print Downloaded file $file\n;
$ftp-binary();
$ftp-get($file);

Ah, another person getting the latest AV file from ftp.symantec.com.
I now want to run the downloaded EXE with some command line switches. I
have tried it with system but it doesn't seem to like using the variable
$file plus switches so I was wondering about how to get the filename out
of the $file variable. If that makes sense.
my @switches = qw( -t -h -f );
system( $file, @switches ) == 0 or die system $file failed: $?

!
!
! hello people,
!
! When I'm trying to server which listens on
! tcp port and
! forking child process i'm getting lot of defunct process when
! the server
! gets lots of requests . Can any body explains why this happens in
! general ?
!
!When a child process terminates, the OS releases all the resources used by
!the process, but keeps the process entry in the process table. This is so
!the parent can read the child's exit status (this is called reaping).
!Processes that have terminated, but whose exit status has not yet been
!reaped are defuct or zombies.
!
!Two basic ways to handle this:
!
!1. Catch SIGCHLD and call wait() from the signal handler to reap the exit
!status.
!
!2. set $SIG{CHLD} = 'IGNORE' in the parent before forking. This tells the OS
!you don't care about the child exit status and it doesn't need to hold on to
!the process table entry. (Note: this does not work on all systems.)
!
!(The defunct/zombies will also go away when the parent terminates)
!
!See also:

Re: couple questions about refs
cool beans, thanks. wow, perl is neat, but i fear it will make me a bad c programmer...;) so i guess there is no concept of stack and heap space when dealing with perl? just that memory will stay allocated as long as there is a way to reach it? hehe, i can't wait to abuse that fact;) christopher On Tuesday 17 December 2002 12:21 am, John W.
