[Ssh-sftp-perl-users] Net::SFTP and publickey

[Jim M. <jim...@no...>]

Hi

I'm trying to setup a connection using publickeys, but I'm getting 
nowhere.  I have a publickey in /export/home/jimmatt/.ssh/id_rsa.  Here's 
the code:

$sftp = Net::SFTP->new($server, ssh_args=>[port => "22"]);
$sftp->get($remote_file, $localfile);

Nothing fancy.  Here's the output I get:

I tried to specify the the identity file by using:

$sftp = Net::SFTP->new($server, debug=>true, ssh_args=>[identity_files => 
"/export/home/jimmatt/.ssh/id_rsa", port => "22"]);

but it didn't like that:

morpheus: Service accepted: ssh-userauth.
morpheus: Trying empty user-authentication request.
morpheus: Authentication methods that can continue: 
publickey,password,keyboard-interactive.
morpheus: Next method to try is publickey.
Can't use string ("/export/home/jimmatt/.ssh/id_rsa") as an ARRAY ref 
while "strict refs" in use at 
/usr/local/lib/perl5/site_perl/5.8.5/Net/SSH/Perl/Auth/PublicKey.pm line 
51.

Any other way to try and specify this? 

Thanks.

You are trying to use what the Net::SFTP POD calls "ssh_args". (You're
trying to pass args to SSH. Your example shows the port argument. I don't
see where you pass "identity_files" argument, but that's what it's
complaining about).

The way to use "%args" is clear as *mud* and not in the SFTP documentation.
This was discussed last April in archive article:
http://sourceforge.net/mailarchive/message.php?msg_id=7695250
And prior to that in
http://sourceforge.net/mailarchive/message.php?msg_id=7114677

To make it easier, I'll recreate it here.

my $sftp = Net::SFTP->new("somehost.domain.domain", ( user => "someuser",
  ssh_args => (  (  [ port => (["1234"]),  identity_files => ([
"/home/user/.ssh/ident_file" ]) ]  )  )
) );

Dave, here comes the rant which you should be expecting. You recall I
discussed this with you almost a year ago. It took me 2 days of trial and
error to unravel the undocumented syntax. I mentioned it again in January
after you created the mailing list and asked everyone to re-input their
requests and observations. Three months later (in April) another user
tripped over this.

Here we are again....

It would be so *easy* just to add an example near "ssh_args" in the POD.
Nothing needs to be "fixed." Just the courtesy of saving people from a
syntax they would never figure out. What's so hard about that? It's been
requested three times over almost a year period. The last time I requested
it, you complained that I hadn't opened a "RT" ticket (which you didn't
mention the two previous times I requested it). I opened the RT
(http://sourceforge.net/mailarchive/forum.php?thread_id=4169065&forum_id=365
14) and still no update of the POD.

You've asked for contribututions back to the project. I've tried. Given the
incomprehendability of "ssh_args" this should have been a welcome solution.
A mere documentation update. Instead it's gone nowhere for almost 12 months
despite 3 requests.

I'm sorry complaining. But, I'm still frustrated over those two days I spent
last year figuring out that notation. The example I provided could save
someone else the same frustration. For the fourth time: Is there any
possibility this example can be placed in the documentation?

Thank you,
Mark

Thanks for the help.  I was using the identity_files parameter, but my 
syntax was slightly off (I wasn't using brackets and parens around the 
name of the file).  All fixed now.

Sorry to stir up this trouble again.  I saw your post previously and 
that's what lead me to figure out how to use the port parameter correctly 
(ssh doesn't live in /etc/services on my boxes). 

Thanks.

I was wrestling with the same lack of documentation
today in a Net::SSH::Perl context.  I came across
your message which sorted me out fast.  Thanks.

I took your sample for Net::SFTP, and applied it thus:

use Net::SSH::Perl;

my $host = 'domain.com';
my $user = 'user';
my $pass = 'pass'; # not used during key-based auth
my $debug = 0;
my $port = 22;
my $identity = '/path/to/.ssh/id_rsa';
my @ssh_args = ( debug => $debug,
                  identity_files => ([$identity]),
                  port => $ssh_port,
                 );

my $command = 'uptime';

my $ssh = Net::SSH::Perl->new($host, @args);

# key-based login:
$ssh->login($user);

# or password-based login:
# $ssh->login($user, $pass);

my ($stdout, $stderr, $exit) = $ssh->cmd($command);

warn ("error performing command: $command ($stderr)") if ($exit);

print $stdout;

exit;
