Hi, I am having trouble trying to figure out why the line: 

$get_xml->unlink($rem_name) or die "Couldn't remove $there: $!";

dies with the following error in the code below: "Couldn't 
remove /tmp/ssh2_test/testing/create_dirs.pl: Inappropriate 
ioctl for device at ssh2_testing.pl line 64." What would be 
the appropriate ioctl? The docs state that the only argument
is file.

The user being used to connect to the remote server has the 
proper permissions to remove the file noted in the above 
error message. The script works as it should up until the unlink call.

Does anyone have any insight or ideas as to what I might 
need to change to get the unlink working?

Thanks!

use Net::SSH2;

my $rem_host = 'xxx.xxx.xxx.xxx';
my $rem_dir = '/tmp/ssh2_test/testing';
my $username = 'username';
my $password = 'password';

my $local_dir = '/export/scripts/xxx/temp/testing';
my (%xml_list, $rem_name, $rem_size, $v);

## connect to remote server with perl and ssh2 module ##

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

## get list of files in the /Outbound dir ##

my $list = $get_xml->opendir($rem_dir) or

while (my $ref = $list->read()) {
  next if ( $ref->{name} =~ m/^\.\.?/ );
  next if ( $ref->{size} =~ m/4096/ );     ## exclude dirs
  print "name: $ref->{name}\n";
  print "size: $ref->{size}\n";

  $rem_name = $ref->{name};

  my $there = "$rem_dir/$rem_name";
  my $here = "$local_dir/$rem_name";

  open WRITE_LOCAL_FILE,">$here" or die "Couldn't open $here: $!";
  sleep(1);

  ## read $rem_file and write locally ##

  my $open_rem_file = $get_xml->open($there) or
  die "Couldn't open $there: $!";
  my $buff;
  while ( $open_rem_file->read($buff,4096) ) {
    print WRITE_LOCAL_FILE $buff;
  }
  close WRITE_LOCAL_FILE;

  ## code to remove the downloaded file ##

  $get_xml->unlink($rem_name) or die "Couldn't remove $there: $!";
}
$ssh2->disconnect() or die "Couldn't do disconnect on ssh2: $!";
