It kills perldoc, but first deletes the temporary files that are in use. Can't ask for more than that :-) Thanks Bill. I had tried finding any open handles by inserting print statements before all 'open' calls and after all 'close' calls but couldn't find any. All I found was that after the first page had been displayed, OUT had been opened and closed. At that point I was hitting Ctrl_C. Is there some better way of determining if there are any open handles at a specific point in a script (preferably a way that doesn't involve specifying the names of any handles) ? If so, a pointer to it might be handy for future use. I also tried some unlink's at various points in perldoc.bat - but they were either being encountered too early or too late. Anyway that's academic, now. Cheers, Rob ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

unlike UNIX, Windoze doesn't seem to be able to delete files that are in

There should be no need for O_EXCL in this situation.

Try checking to see if the file exists here - can't delete what isn't there.

You could also try closing OUT or TMP or whatever FH is being used
prior to the unlink.

It finally all made sense - when I grasped the basics of what's happening.
When I run 'perldoc' it comes up one page at a time with 'more' - and once
I've got to the bit I
want to read, I then kill it with Ctrl-C.
When I do that the temporary file is not deleted - it only gets deleted if
'perldoc' terminates in the normal fashion.
So, the *next* time I run 'perldoc' there's a chance that the (arbtrarily)
designated temporary file already exists - in which case O_EXCL kills it.
So I thought I'd get real cute and write into perldoc.bat a sigint handler
routine that unlinks the temporary file and exits when Ctrl-C is hit.
And it works beautifully - except that it won't delete the file.
I'm not sure if that shortcoming exists because I'm reading the file that
I'm trying to delete - or because 'unlink' is simply something that can't be
done on Win32 from a sig-int-handler routine. (I can't find any open
handles, so I suspect it's the latter . wouldn't be hard to check if I
can be bothered.)
Anyway, seems there's a few simple options for dealing with the problem.
I find it interesting that when my perldoc call fails, then the file that
O_EXCL refused to allow to be opened, gets deleted anyway. Can't see the
point of having an 'O_EXCL' there . maybe it serves some purpose for a
different OS. (I guess, for me, it has served in keeping down the number of
'perldoc1.*' files that exist in my temp folder.)
Here's the handler code I tried, btw.
$SIG{INT} = \&my_handler;
sub my_handler{
print "Aborting\n";
#system("del perldoc1.*"); # "Can't spawn cmd.exe"
#chmod 0666, $my_tmp; # doesn't help
my $u = unlink $my_tmp; # $my_tmp is the temp file
if($u) {print "$my_tmp deleted\n"}
else {print "Cleanup FAILED!!!\n"}
kill 'ABRT', $$;
}
prints:
Aborting
Cleanup FAILED!!!
Thanks guys.

Two problems, when the index file is created, the file needs to
be opened for output, instead of:
open (I, "index.idx");
you need:
open (I, ">index.idx") || die can\'t open output file index.idx";
Second problem:
The perl Cookbook assumes use of a Unix OS. On a Windows OS
files that contain binary data, like your index file, require
use of the binmode function.
After the open (INDEX, "$index_file_name") or die ("Can't open $!\n");
insert a: binmode(INDEX);

Read list of servers from a file???
Hello perl gurus,
I have a Perl script that I use to search for files of type *.mdb. I
can currently search only 1 machine at a time. I need to search the entire
network though. I have another script that generates a list of all servers
on the network (120 +/-). I have tried unsuccessfully to modify the search
script to open the servers.txt file and read through it 1 server at a time.
passing each server name to the search routine. I have been unsuccessful for
2 days! Any guidance would be much appreciated. Here is the search script
below:
#! D:\Perl\bin\perl.exe -w
eval 'exec D:\Perl\bin\perl.exe -S $0 ${1+"$@"}'
if 0; #$running_under_some_shell
use strict;
use File::Find ();
# Set the variable $File::Find::dont_use_nlink if you're using AFS,
# since AFS cheats.
# for the convenience of &wanted calls, including -eval statements:
use vars qw/*name *dir *prune/;
*name = *File::Find::name;
*dir= *File::Find::dir;
*prune = *File::Find::prune;
# Traverse desired filesystems
File::Find::find({wanted => \&wanted}, 'NTSERVER /c$');
exit;
sub wanted {
print "$File::Find::name\n" if /\.mdb$/;
}

RE: NET::Telnet
First, if you are telnetting from a non Windoze PC, you must turn off NTLM
authentication on the host.
This works on an NT box:
use Net::Telnet;
use strict;
use warnings;
my $telnet = new Net::Telnet ( Timeout=>10, Errmode=>'die');
my @jim="";
my $frank="";
$telnet->open('192.168.174.108');
$telnet->waitfor('/Username: $/i');
$telnet->print('Administrator');
$telnet->waitfor('/Password: $/i');
$telnet->print('12345');
$telnet->waitfor('/\>$/i');
$telnet->print('"show users"');
@jim=$telnet->waitfor('/\>$/');
Its similar for W2K except that Username is login.

The example does a "tell" on the main file, and puts the results in the index. But then it computes "seek" values on the index. You could get around that by doing a "tell" every time you write the index, and keeping _them_ somewhere. Of course, if you keep them in a file (a meta-index), you rapidly disappear into an infinite regress.

He does address this issue in 8.11 (a couple pages further into the recipes about file access). To be fair he does warn in the preface that they tested on BSD, Linux and SunOS and that some examples may not work on non-POSIX systems.

True, however I thought the limitation was that you could only "seek" to locations provided by "tell". Given that the index is generated using tell, seeking to the locations should work, independant of the stupid \015\012 crap. cheers, bj ___ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs

Mark, you'd probably win that bet. I just searched back through my notes of the time
(what did I do before I got my PDA?) and can't find any mention of having changed the
term type. I remember sending a couple of SOSes to the list and don't recall that
being in any of the suggested solutions or comments. I'm curious now though, and will
keep your response in my suspense list for a rainy day. Would be nice to be able to
query those legacy systems instead of having to log in to 'em manually.

Installing Libwww-perl on ASPerl 5.6.1 Build 633 with PPM3
I have had considerable trouble installing libwww-perl on my AS Perl 5.6.1 Build 633 on WinNT 4.0. I had been having some strange configuration problems with Perl, so I completely uninstalled AS Perl 5.6.1 Build 62x and installed AS Perl 5.6.1 Build 633. The installation went well and resolved all my configuration problems. I was able to get all the packages that I had been using, except for libwww-perl. I have switched to PPM3 and as long as I remember the new syntax, I like the app. Here is what I get when I try to use PPM3 to install libwww-perl: >D:\Projects\Perl>ppm3 >PPM - Programmer's Package Manager version 3.0.1. >Copyright (c) 2001 ActiveState SRL.

Please 'search' >for it first. >ppm> I search for the package, find the package and ask PPm3 to install the package, and it replies - "'search' for it first." I usually respond with something impolite and drop the matter. This morning after reading a note about libwww-perl and being available on Active State, I decided to try again. I got the above results from PPM3. So then I tried PPM. PPM has been non functioning since the install of Build 633. PPM spews out at me: >D:\Projects\Perl>ppm >Element 'IMPLEMENTATION' must contain a 'CODEBASE' element. at D:/Bin/Perl/site/ >lib/PPM.pm line 1684. >Element 'IMPLEMENTATION' must contain a 'CODEBASE' element. at D:/Bin/Perl/site/ >lib/PPM.pm line 1684. >Element 'IMPLEMENTATION' must contain a 'CODEBASE' element. at D:/Bin/Perl/site/ >lib/PPM.pm line 1684. >Element 'IMPLEMENTATION' must contain a 'CODEBASE' element. at D:/Bin/Perl/site/ >lib/PPM.pm line 1684. >Element 'IMPLEMENTATION' must contain a 'CODEBASE' element. at D:/Bin/Perl/site/ >lib/PPM.pm line 1684. >Element 'IMPLEMENTATION' must contain a 'CODEBASE' element. at D:/Bin/Perl/site/ >lib/PPM.pm line 1684. >PPM interactive shell (2.1.6) - type 'help' for available commands. >PPM> search libwww >PPM> The PPM prompt is returned immediately after the "search libwww". Any suggestions for getting libwww-perl installed or for getting PPM working again? Thanks. James H.

RE: NET::Telnet
Greetings,
I too had alot of trouble getting Net::Telnet to work properly,
it seemed to continuously stop for no apparent reason, with very
poor performance. As well as not being able to make it non-block
on win32.
I had to eventually write a direct TCP client to get a proper
level of performance..etc..
Just my .02,
-Lenny

Carter, what you're saying may work on Unix systems, but after 2 weeks of
hair-pulling last year, I gave up trying to use Net::Telnet on legacy Univac
and Dec systems. The module just couldn't handle the odd terminal emulation
escape sequences that were being fed to it (especially on the Univac) and I
was unable to reliably establish and maintain terminal sessions on those
machines. Finally had to "brute force" ftp files up to those boxes without
being able to do the file existence/status checking planned for in my
original design. Net::Telnet users beware.

The Prompt is a regular expression that matches the
commandline prompt from the remote shell. That means
you'll want to match the prompt for the user you are
logging in as. If I log into one of my remote windows
machines through a telnet server and I see I have a
prompt like so, "C:/" I'll need to match that within
my code as prompt.
If the prompt isn't matched in the time specified in
Timeout then the script will either return false or
die based on what Errmode is set to, return or die respectively.
NET::Telnet Defaults:
Timeout = 10
Host = "localhost"
Errmode = "die"
Prompt = "/[\$%#>]$/" # matches most unix shells.
Port = 23
This is how you could establish a connection with a
windows machine with NET::Telnet (Untested).
use strict;
my $TIMEOUT = 30;
my $PROMPT = "C:/";
my $HOST = "foobar.foo.com";
my $USER = "Bob";
my $PASS = "password";
$telnet = Net::Telnet->new( Timeout => $TIMEOUT,
Prompt => $PROMPT,
Host=> $HOST,
Errmode => "return");
$telnet->login($USER, $PASS);
# Test here for success if using "return".
my $msg = $telnet->errmsg();
if ($msg) {
print "$msg\n";
$telnet->close;
# do whatever you want here.
}
Hope this helps.

If the prompt isn't matched in the time specified in
Timeout then the script will either return false or
die based on what Errmode is set to, return or die
respectively.
NET::Telnet Defaults:
Timeout = 10
Host = "localhost"
Errmode = "die"
Prompt = "/[\$%#>]$/" # matches most unix shells.
Port = 23
This is how you could establish a connection with a
windows machine with NET::Telnet (Untested).
use strict;
my $TIMEOUT = 30;
my $PROMPT = "C:/";
my $HOST = "foobar.foo.com";
my $USER = "Bob";
my $PASS = "password";
$telnet = Net::Telnet->new( Timeout => $TIMEOUT,
Prompt => $PROMPT,
Host=> $HOST,
Errmode => "return");
$telnet->login($USER, $PASS);
# Test here for success if using "return".
my $msg = $telnet->errmsg();
if ($msg) {
print "$msg\n";
$telnet->close;
# do whatever you want here.
}
Hope this helps.
Cheers,
Carter.

"N" packs or unpacks an unsigned long, which according to ANSI "C" goes to
4 gig; it's hard for me to believe you can overrun this in a 3mb file.
What I think I would try instead is to put the index file into binary mode.
right after you open it (hint:
binmode I;
). What I fear is going on is that somewhere along the line you generate a
byte whose value is 0x10. If that happens under Windows 32 and you're not
in "binmode", the "C" runtime will "expand" this to 0x13 0x10, and at that
point, you're dead in the water.
So am I saying that Tom Christiansen and Nathan Torkington are wrong and
I'm right? Not really. I don't own a copy of this book, but I suspect
you'll find somewhere in the front matter something about the target system
being some flavor of Unix. U**x doesn't need the "binmode", because the "C"
RTL doesn't mung the I/O streams. On most other systems, though, it gets
munged to make the data stream look a unix-y as possible to your code.
Under Windows, this means translating 0x10 (= ) to 0x13 0x10 (=
) on output, and the reverse on input. Other things happen under other
operating systems.
If you look in the "perlport" documentation (a.k.a. "Writing Portable
Perl") you will see:
Because of the "text" mode translation, DOSish perls have limitations in
using "seek" and "tell" on a file accessed in "text" mode. ... If you use
"binmode" on a file, however, you can usually "seek" and "tell" with
arbitrary values in safety.

RE: NET::Telnet
Jitranda, I gave up trying to figure out what to use as a prompt for Net::Telnet when connecting to Windows' telnet server. Maybe someone out there will enlighten us both.

In theory, yes, _provided_ the Telnet service is set up to do username/password authentication. This is not the default. In practice, there appear to be significant problems figuring out what you should tell it the prompt string is, because Microsoft embeds all sorts of escape sequences in it. > and start Any program like Notepad on target machine? In theory, yes. In practice, of course, Notepad displays on the target machine's desktop, which probably does you as the owner of the telnet link no good at all.
