ashok.g has asked for the wisdom of the Perl Monks concerning the following question:

Hi folks,
I'm trying to connect to remote servers using Net::SSH::Expect. Between the servers the SSH keys were distributed.
The connection is always happening as user apache even if we specify a user (existing or not existing)in the connection.
Here is the subroutine I used in connecting to remote host via a CGI script.
sub SSH_Reference {
        my ($rip,$rusr) = @_;
        chomp($rip,$rusr);
        my $ssh = Net::SSH::Expect->new(
                                    host     => $rip,
                                    user     => $rusr,
                                    timeout  => 15,
                                    raw_pty  => 1
                                      );

        eval{
               $ssh->run_ssh();
        };

When I print $@ it is saying that /var/www/.ssh canno't be created.


Can anyone tell me why this is happening?

    You need to show some code to get proper response. Are you passing the user name while creating the Net::SSH::Expect object? Document says you need to pass user name even for public key authentication 
    # Note that when you use public-key authentication you won't need to s
+et the 'password' constructor attribute
# but you still need to define the 'user' attribute.

      print "$@";
$test = $ssh->read_line();
print "$test";

      Here $test is printing as Could not create directory '/var/www/.ssh'. on my browser.

      I tried with the ncoadmin (a non-root, existing system user). But the same error I'm getting when I tried to run this connection by sending the $rusr as 'blahblah'...

        What effective user is this script running under? Do they have permission to write to /var/www ?

        Net::SSH is just a wrapper around your local ssh command, so could this be an underlying permissions issue?

        Maybe Net::SSH::Perl is an option?
