[Ssh-sftp-perl-users] NET::SFTP problem with RSA key

[Alessandro De M. <ale...@tr...>]

Hi all,

I beg your help for a problem I have trying to use the Net::SFTP module.
I'm trying to create a script that will move files using an sftp
connection.

I will have to use just the publickey authentication.

I have written a little script just to connect and make sure I can
simply put a file there, just as a test, but even if the "password"
authentication works, I can't have the publickey to get into action.

here the script
##########################################################
#!/usr/bin/perl -w

use Net::SFTP;

$sftp_server = "my_server";
@keys = ("/home/myuser/.ssh/id_rsa");
my $sftp = Net::SFTP->new($sftp_server, (
				user => 'myuser', 
				debug =>3,
				protocol =>'2,1',
				options=>["IdentityFile ~/.ssh/id_rsa"]
				));

I have tried a NUMBER of combination, even passin the \@keys or having
identity_files => ["~/.ssh/id_rsa"].

I have also copied "id_rsa" to "identity" and removed the IdentityFile
to have the key to be picked up as default.

####################
and I have even tried just the use Net::SSH::Perl module:

my $ssh = Net::SSH::Perl->new($sftp_server, debug =>'3', 
			identity_files => ["~/.ssh/id_rsa"] );
$ssh->login('myuser');
my($stdout, $stderr, $exit) = $ssh->cmd('ls');
print $stdout;


Running on fedora 6. perl, v5.8.8

modules installed through cpan. 
Module  = Net::SFTP              (DBROBINS/Net-SFTP-0.10.tar.gz)

#### in case you wonder:
[myuser@laptop10 .ssh]$ ls -l
total 36
-rw------- 1 myuser myuser  440 Jun  4 17:06 authorized_keys
-rw------- 1 myuser myuser 1679 May 14 14:07 id_rsa
-rw-r--r-- 1 myuser myuser  411 May 14 14:07 id_rsa.pub
-rw-r--r-- 1 myuser myuser 6813 May 25 16:03 known_hosts
-rw-rw-r-- 1 myuser myuser 1192 Jun  5 11:08 known_hosts2

#### I can also successfully ssh to the server above using my id_rsa
key:

[myuser@laptop10 ~]$ ssh my_server
Last login: Tue Jun  5 11:22:25 2007 from 217.207.105.92
Access for authorised personnel only
[myuser@my_server myuser]$ 

here is the debug I get:

Could you please help me in identifying what am I doing wrong?
