Net::SSH2::Channel failure on Windows XP

bgi has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

Yesterday I thougt that I got it...and today? Another error: This time the perl-interpreter aborts... (is this correct? aborts?)

When I was trying to play these code:

use strict;

use Net::SSH2;
#use Net::SSH2::Channel;

my $ssh2= Net::SSH2-> new();

$ssh2-> connect('Ip address') or die;
    
if($ssh2-> auth_password('user', 'pass')){
    
    print "ok";
    
    my $chan2 = $ssh2-> channel();
    $ssh2-> ($chan2);
    print $chan2 "uname\n";
    
    
}else {
    
    print "auth failed";
}
[download]

It prints the -ok- and then a few seconds later, an error message pops up...this is what dr.watson says..

What to do?? What do you think: Windows Error, Error in Module, perhaps the module is not running correct in Windows?

For all the non-Germans here: the error message basically says "segmentation fault". `if($ssh2-> auth_password('user', 'pass')){ print "ok"; my $chan2 = $ssh2-> channel(); $ssh2-> ($chan2);` [download] That last line looks suspicious. `$foo->($stuff)` treats `$foo` as a sub ref, and passes `$stuff` to it. I don't think `$ssh2` is a sub ref, so try to do without that line. (Still perl shouldn't crash on it IMHO).	[reply] [d/l] [select]
Re: Net::SSH2::Channel failure on Windows XP by zentara (Cardinal) on May 21, 2008 at 16:43 UTC
This is just a WAG, but maybe you need to solidify your auth, before you try and get a channel? Also what is $ssh2-> ($chan2);? `#instead of if($ssh2-> auth_password('user', 'pass')){ print "ok"; my $chan2 = $ssh2-> channel(); $ssh2-> ($chan2); #what is this step? print $chan2 "uname\n"; #try it without the if block $ssh2->auth_password('user','pass') or die "Unable to login $@ \n"; + my $chan = $ssh2->channel(); + $chan->blocking(0); + $chan->exec('ls -la'); + while (<$chan>){ print } + #$chan->close;` [download] I'm not really a human, but I play one on earth.

test suit..? The only thing I know is `perl -e "use Module::Name;"` Hmm I guess the Code is correct...I copied ist out of these forum while I was searching code examples...it works also without these line... It breaks at this line: `my $chan2 = $ssh2-> channel();` Any ideas..?	[reply] [d/l] [select]

Re: Net::SSH2::Channel failure on Windows XP by syphilis (Archbishop) on May 22, 2008 at 07:52 UTC
Does this do what you want: `use Net::SSH2; use warnings; use strict; my $buflen = 100; my $buf = '0' x $buflen; my $ssh2 = Net::SSH2->new(); $ssh2->connect('IP Address') or die; $ssh2->auth_password('user','pass') or die "Unable to login $! \n"; my $chan1 = $ssh2->channel(); $chan1->blocking(1); $chan1->exec('uname'); $chan1->read($buf, $buflen); print "BUF: ", $buf, "\n"; $chan1->close; __END__` [download] That works fine for me on Windows with perl 5.8.8. (The script you posted did not.) But it segfaults on perl 5.10.0 on Windows. (There are issues with Net::SSH2 on perl 5.10 ... and not just windows issues. See eg http://rt.cpan.org/Ticket/Display.html?id=36071.) Cheers, Rob	[reply] [d/l]
