RE: Help needed -- Net::telnet gives errors
I am also working on a project that requires passing a password via the web,
and obviously did not want to do so URL encoded with GET. My suggestions:
A. Use CGI.pm's param() method to get your
form data. I second Carl's question as to why
you would manually parse the form data when
you can get all of the form data into a hash
by simply doing
use CGI;
my $query = new CGI;
my %formvalues = $query->Vars;
B. The way I went about the password issue
without using GET, or even a POST with hidden
fields (better but still not ideal), is to
use CGI::Session to generate a unique session
ID once the username and password are authenticated.
Now I use the session ID in hidden fields where
I can, URL encoded using GET where I have to, but
the username and password are not being passed
around insecurely. The CGI::Session docs are
pretty decent on the examples, so you shouldn't
have much trouble with it. You can also use the
generated session ID as a cookie and fake
statefulness that way.
Your solution may require more effort because you are using a telnet session
and authenticating that way, where I'm just authenticating against either
.htaccess files or MySQL columns, so you've got another link in the chain
there.
But then again telnet passes username/password in plain ascii, so we're back
to the security issue on that end of it. Have you considered initiating an
SSH session rather than a telnet session? Just a thought...

It's because you said the method was GET but you tried to retreive the
value from the form as though the method was POST. When the method is GET
the form values are passed via the $ENV{QUERY_STRING}. I strongly suggest
that the GET method NOT be used when you are passing a password unless you
only want to keep the password secret from those who don't know how to
view/source on an HTML page. Also why are you "hand-parsing" the form
input anyway when the CGI module has already done it for you?

win32::api & CoCreateInstance
I am having trouble figuring out the input parameter
list for the CoCreateInstance function. I am a Unix
guru who is new to Windows programming. This is what I
garnered from msdn:
STDAPI CoCreateInstance(
REFCLSID rclsid,
LPUNKNOWN pUnkOuter,
DWORD dwClsContext,
REFIID riid,
LPVOID* ppv
);
But this is greek to me, even with the further
explanation provided by Microsoft at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcedcom/html/cerefCoCreateInstance.asp
How would I represent the input parameter list with
the win32::api module? I looked at the win32::api
docs, which were helpful, but I am still not sure that
I am doing things right. Here is my code:
use Win32::API;
$CoCreateInstance = new Win32::API('ole32',
'CoCreateInstance', 'SPNSP', 'I');
if(not defined $CoCreateInstance) {
die "Can't import API CoCreateInstance: $!\n";
}
As you can see, 'SPNSP' is what I came up with. It is
an intelligent guess on my part. Am I right? How can I
learn more about these parameters? Thanks for any help.

I can't get anything sensible from 'buttonwidth' with either 5.6.1 or 5.8.0.
For me it produces the error "Failed to AUTOLOAD
'Tk::__ButtonContainer::indexedbutton".
I don't understand OO perl at all well - and I don't use Tk very much - but
it seems to me that the above error is to be expected because there is no
'Tk::__ButtonContainer::indexedbutton' subroutine. Columns.pm does contain
an 'indexedbutton' subroutine, but it exists in package Tk::Columns, *not*
in package 'Tk::__ButtonContainer'.
None of the demos that ship with the cpan distro utilise 'buttonwidth'. You
should probably check with the author - maybe he has made a mistake.
That's about all that *I* can come up with.
Cheers,
Rob

Stuck in Find::File
HI
I am trying to log on to my unix server (from my windows m/c) and list the
directory structure. I came across this File::Find module . It works fne on
my windows m/c. but when i try to telnet to my unix m/c and set the base dir
as xxx it gives the following error
"Can't stat /home/: No such file or directory".
If i just give a "ls " command on the samr dir it works fine.
the code used is as follows:
Code
===
find(\&edits, $basedir);
sub edits()
{
print "File name is $_\n\t\tFull path is $File::Find::name\n";
}
where $basedir is the home directory.
Also is it possible to traverse each directory one by one?
TIA
Ashish

As you're using word to create the file, word itself will lock the
file against deletion while word has the file open. Have you checked
after the above code to see if word has terminated? This snippet from
the Win32::OLE docs should do that.
while (my $Word = Win32::OLE->GetActiveObject('Word.Application')) {
sleep 1;
}
unlink($fullout);
