[Ssh-sftp-perl-users] NET::SSH2 Exaples, listen and tcpip

[Wolfgang F. <wf...@un...>]

Hi List,

reading this list(archive) and the CPAN documentation for Net::SSH2 i
was able to get scp, exec and the shell functionality to work,
but i have no clue how to get the tcpip and listen functions to work.

I want to open a tcp-forwarding, with the listening side on the server
and the destination on the client-localhost side (where the perl code is
running) , i think the listen function can do this but i don=C2=B4t know ho=
w
to set the parameters. The documentation on CPAN does not make sense to
me also it is very short.

does any body use the tcpip and listen features of Net:SSH2 and is
willing to send the list and me, some examples and code snippets please.

thanks ...

[Ssh-sftp-perl-users] Command output to local STDOUT

[Heinz P. <hei...@as...>]

Hi,

with

my $cmd = "testprog.pl"; 
my $ssh = Net::SSH::Perl->new($ip, debug=>'0', interactive=>'0'); 
$ssh->login($user, $password); 
($stdout , $stderr, $exit) = $ssh->cmd($cmd); 
print $stdout;

I can execute testprog.pl:

select STDOUT; 
$| = 1; 
print "Programmablauf "; 
for my $i(0..100) { 
sleep(1); 
printf "%3d \%\b\b\b\b\b", $i; 
} 
print "Fertig!\n";

on a remote machine.
This works fine, but of course I get only the finally output
"Programmablauf Fertig!".
Is it possible to see the whole output from testprog.pl on my local
STDOUT?

Thanks
        
        
        
        

[Ssh-sftp-perl-users] Net::SSH2, how to get exit_status

[Pierrick LE G. <pie...@le...>]

Hi,

Using Net::SSH2 I would like to get the exit status of my last remote
command, how can I do this?

I've read Net::SSH2::Channel perldoc several times but no example is
given, and I really need one. The following code sample does not work:

my $chan = $ssh2->channel();
$chan->ext_data('merge');
$chan->shell();

print $chan 'perl /home/z0rglub/work/talend/outerr2.pl; echo $?', "\n";
@output = map {chomp; $_} <$chan>;
$exit_status = $chan->exit_status();
print join("\n", map {'command 1: '.$_} @output), "\n";
print '$exit_status: ', $exit_status, "\n\n";

The output is:

command 1: warning 1
command 1: warning 2
command 1: salut 1
command 1: 10
$exit_status: 0

And of course, I would like the $exit_status to be 10.

Bye

[Ssh-sftp-perl-users] Net::SSH2, how to read STDERR separately

[Pierrick LE G. <pie...@le...>]

Hi,

Using Net::SSH2 (which seems to be the official SSH client nowadays) I
would like to read STDERR separately from STDOUT, how can I do this?

I've read Net::SSH2::Channel perldoc several times but no example is
given, and I really need one.

Re: [Ssh-sftp-perl-users] Net::SFTP occasional segmentation fault

[John D. <jd...@lo...>]

I figured out this problem.  It was actually an issue with Net::SSH::Perl
and Crypt::DH.  The answer can be found at this link.

Subject: Net::SFTP occasional segmentation fault

 

HI,

I have been trying to get SFTP going in a perl script but not having much
luck, so to simplify matters, I have been trying to connect using the psftp
client, but I am getting the same results.  The odd thing is that the seg
fault happens most of the time when I launch psftp from a command line, but
occasionally I get a little further before getting a permission denied
error.  If I run it through the perl debugger, I never get the seg fault.
Below are some sample outputs.

 

This is what it looks like from the command line:

The _session_channel method is used by several methods of SSH2.pm
module: cmd, shell, open2 in order to open client session channel. I
can not say that will happen if we do not duplicate STDIN for these
cases.
It is really difficult to understand this module without any
development documents and almost without comments.
Maybe you can perform some tests without duplicated STDIN. I can say
only that receiving of files through SFTP works fine in this case.

I'm the current maintainer, but I don't know why we do that - it was there when I took over the code.

Perhaps the better question is, what happens if we no longer do it?  Will it break anything important?

[Ssh-sftp-perl-users] Guru's advice is needed regarding SSH2.pm

[Alexander K. <ale...@gm...>]

Hi,

This question is not to users but to authors of Net:SSH:Perl module.

Could anybody tell me why we duplicate STDIN in _session_channel of
SSH2.pm please?

my $channel = $cmgr->new_channel(
ctype => 'session', local_window => 32*1024,
local_maxpacket => 16*1024, remote_name => 'client-session',
rfd => _dup('STDIN', '<'), wfd => _dup('STDOUT', '>'),
efd => _dup('STDERR', '>'));

It causes issues like "SFTP::do_stat returns error if <ENTER> key is
pressed" (sent 2006-11-29)

I can not find the answer by myself. So, I decided to ask here about
this. Maybe together we can find the fix of this annoying issue.

Thanks,

[Ssh-sftp-perl-users] Net::SSH2 version 0.10 released

[David R. <dbr...@cp...>]

I apologize for the delay, but in my defense, a tree fell through my bedroom 
and nearly killed me (not one of those wimpy east coast trees, a ginormous 
Pacific cedar).  Fortunately injuries were minor and insurance is paying.

Here are the changes for Net::SSH2 0.10, which you can get at 
http://search.cpan.org/dist/Net-SSH2 as soon as it's been indexed:

0.10  2007-02-24  dbr  (svn revision 52)
        - Net::SSH2::SFTP::realpath fix (Hugues Lafarge).
        - Make compatible with perl 5.6 (rt.cpan.org #22821, SISYPHUS); 
required
           minimal changes to typemap and use <version> lines (untested).
        - libssh2 0.13 seems to work, libssh2 0.14 still fails some tests.
        - Add missing Net::SSH2::PublicKey object.
        - Use (arbitrary) 8K buffer in scp_get and scp_put methods, rather
           than trying to transfer the whole file at once (rt.cpan.org 
#20679).
        - Remove 'use Term::ReadKey'; it's already 'require'd in the keyboard
           authentication callback (rt.cpan.org #22786).
        - Provide libssh2 with Perl's allocator callbacks and use Perl_malloc/
           Perl_mfree instead of bare malloc/free (rt.cpan.org #23930).

Note that there are some test failures with libssh2 0.14 so I recommend using 
0.13 or 0.12; I'm not going to worry too much about 0.14 with 0.15 nearly 
out; when 0.15 is released I'll make sure Net::SSH2 works with it.

With these fixes there are no active bugs in rt.cpan.org for Net::SSH2.  As 
always, detailed bug reports and especially patches are welcome.

[Ssh-sftp-perl-users] Connection Timeout With Net::SFTP

[Kenneth B. <ke...@te...>]

 I was wondering if you can help me get the Net::SFTP module working. I am
very new to the Linux world and I used the following command to install the
module:

perl -MCPAN -e 'install Net::SFTP'

I went through the installtion which I thought was successful. When I
execute the following I get a connection timeout:


#!/usr/bin/perl

# Use statements.

use strict;
use warnings;
use Net::SFTP;

# Connect to our SFTP stage server.
my $sftp = Net::SFTP->new("XXX.XXX.XXX.XXX",
                          user=>"XXXXXXXX",
                          password=>"XXXXXXXXXX",
                          debug=>1);



I get the following output:

aabox02: Reading configuration data /root/.ssh/config
aabox02: Reading configuration data /etc/ssh_config
aabox02: Allocated local port 1023.
aabox02: Connecting to 208.109.219.89 , port 22.
Can't connect to 208.109.219.89, port 22: Connection timed out at
/usr/lib/perl5/site_perl/5.8.0/Net/SSH/Perl.pm line 208.

I have also run the following to insure the SSH module is installed:

perl -MCPAN -e 'install Net::SSH'

My perl version is 5.8 running on Red Hat Linux:

Linux version 2.4.21-32.ELsmp (bhc...@tw...) (gcc
version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)) #1 SMP Fri Apr 15 21:17:59
EDT 2005

I have no problem accessingsftp if I use the command line sftp program.

Any help you can provide would be great.

Thanks,

Ken

Re: [Ssh-sftp-perl-users] Net::SSH::File->read problem

[Cole T. <col...@gm...>]

Here's one more tidbit - I'm hoping somebody can offer help here
because I'm ready to fall back on using an Expect script if I can't
get this working...

In any case, if I try to do a ->read, it sometimes fails.  I added
this debugging line:

printf STDERR "There was a problem with the read: (%s) (%s) (%s)\n",
$!, $ssh2->error, $sftp->error;

This seems to yield a lot of:

There was a problem with the read: (Resource temporarily unavailable)
(-30) (LIBSSH2_ERROR_SOCKET_TIMEOUT)

Can anybody offer any help/suggestions?

Thank you for the replay. I've tried, but got the same result...
But I did another test and, really, it can be clue.

What I do:
1. execute script with _long_ command
2. measure time of executing for script - really the time depends on 		sleep(5);
3. check if the process exists.

It looks like the $chan->exec() detach control terminal. It's very useful
behavior but how can I manage it (I mean how to define detach or keep stdin,
stdout etc)?

May I ask you to help me in this? Probably I just missed something important in
the manual for Net::SSH2.


[root@lx-sles ~]# cat 123
#!/usr/bin/perl -w
use strict;
use Net::SSH2;

my $ssh2 = Net::SSH2->new();
print "connect fail\n" unless ($ssh2->connect('127.0.0.1'));
print "password fail\n" unless ($ssh2->auth_password('root', 'xxxx'));
# test2

my $chan=$ssh2->channel();
$chan->exec('LIMIT=10 ; for ((a=1; a <= LIMIT ; a++)) ; do expr 2 \* $a ; sleep

Both your test1 and test2 scripts below works fine for me (using Gentoo Linux, 
perl 5.8.8, Net::SSH2 0.09).  Try adding a sleep(5) before you start reading 
the output, to see if it's just an output delay.

[Ssh-sftp-perl-users] Net::SSH2 don't see the result of commands

[Serge L. <ser...@gm...>]

HI,

I'm trying to see the result of executing "uname -a" on my host.
Unfortunately, there is no  output from the script.
Could you please point me what I do wrong?

I tried to do it with opensuse 10.2 and  FC 5, perl v5.8.8,
*libssh2-0.14 , Net-SSH2-0.09
*
Note:  Everything is ok If I do the following

$chan->exec('uname -a > /tmp/my');
my $sftp = $ssh2->sftp() or die $!;
my $fh = $sftp->open('/tmp/my') or die $!;
print $_ while <$fh>;

so the lib and module are working, but I guess it's a bad way.


Script:
--------------------------------------8<-----------------------------------------
#!/usr/bin/perl -w
use strict;
use Net::SSH2;

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

print "connect fail\n" unless ($ssh2->connect('127.0.0.1'));
print "password fail\n" unless ($ssh2->auth_password('root', 'xxx'));

# test1
my $chan=$ssh2->channel();
$chan->shell();
print $chan "uname -a\n";
print "LINE : $_" while <$chan>;
$chan->close;

# test2
 $chan=$ssh2->channel();
$chan->exec('uname -a');
while (<$chan>){ print $_ } ;

[Ssh-sftp-perl-users] Net::SSH::File->read problem

[Cole T. <col...@gm...>]

Hi all - I'm having an interesting issue with trying to read a file
across an sftp connection.  Namely, if I try to call ->read on a file
that I open across the sftp connection, the connection no longer seems
to be available for other traffic.

I've attached a small sample script to demonstrate (the equivalent of)
what I'm trying to do.  The idea is that, after getting a file
listing, I'm trying to read in each file that passes a certain regex.

The problem is that after the first read in, all subsequent stats
calls (or read calls, if I were trying them) fail with a "Resource
temporarily unavailable" in $!.  The interesting bit is that if I
remove the read call on line 38, it gets rid of the problem (even if I
leave the ->open call in).

Anybody have any thoughts?

Thank you for your response.  I went ahead and re-built libssh2 to get

This appears to be a libssh2 issue and not specifically Net::SSH2; the perl 
module is finding libssh2 but libssh2 can't find some of its symbols.  How 
did you build libssh2?  Did you run its tests?

Does this command hangs the terminal also if you execute directly on the
Unix box? You can try
the following to detach it from the terminal
=20
$ssh->cmd("nohup service snmpd start");

Thanks for prompt reply. I tried this piece of code but don't see pl
script exiting on the windows box. The command is successfully executed
on the remote Unix server.

=20

I go to the unix box and stop the service and then perl script exits
successfully.

=20

Does this give any clue what's going on ???

=20

I tried giving the command "touch /tmp/abc.txt" and the file is created
on unix server and perl scipt also exits. Why perl script behaves
differently for these 2 different commands on remote box ?

=20

Thanks

I don't think the connection is dropped after a command is send. You
might want to add:

=20

$ssh->cmd("exit");

=20

to your script to close the connection.

Hi,

=20

I am running a simple script to execute a command on a remote linux
server. The machine on which pl script is running is windows XP (no
cygwin installed). Below is the script and output

=20

#testing script

use Net::SSH::Perl;

=20

$targetIP =3D shift;

$userName =3D shift;

$password =3D shift;

$sourceFileName =3D shift;

$destinationDir =3D shift;

=20

my $ssh =3D Net::SSH::Perl->new($targetIP, debug=3D>1);

$ssh->login($userName,$password);

=20

$ssh->cmd("service snmpd start");

=20

print "Bye";

=20

The debug output is=20

=20

=20

=20

The scipt does not exit after sending command to remote box. I can see
service "snmpd" running on remote Unix server but no message "Bye" on
windows box.

=20

Does anyone has faced this issue ? Any pointers will be highly
appreciated as I need this script to run ASAP.

=20

Thanks
