[Ssh-sftp-perl-users] Calc.pm issues

[<Fra...@gl...>]

Hello,
I want my perl program to connect to a server using SSH.
I want to connect to remote servers I've never been before.
In fact, the program's aim will be to copy a public key on several =
remote servers. Here is the error raised by perl : Not an ARRAY =
reference at /usr/local/share/perl/5.8.4/Math/BigInt/Calc.pm line 222. =
As far as I am concerned I had lots of difficulties to get the =
Net:SSH:perl lib to compile through the cpan shell.
Here is my code (In this case, I manually copied the pub key on the =
remote server)
$adresse_ip=3D"192.168.100.54";
$user=3D"user";
$pass=3D"xxxx";
$params{debug} =3D 1;
$params{interactive} =3D 0;
$params{protocol} =3D '2,1';

$ssh =3D Net::SSH::Perl->new($adresse_ip,%params,options =3D>["BatchMode =
yes","RhostsRSAAuthentication no"]); $ssh->login($user, $pass); =
($stdout, $stderr, $exit) =3D $ssh->cmd("ls");
print $stdout;
print $stderr;
print $exit;
Here is the debug output :=20

Many thanks for your help.
