in reply to Net::OpenSSH pass command

Enable debugging on Net::OpenSSH and/or ssh in order to see what is going on:
# Before using Net::OpenSSH: $Net::OpenSSH::debug = ~512; ... # And then, on the constructor my $ssh = Net::OpenSSH->new(..., master_opts => '-vvv');

      You need to pass the verbose flag to ssh command as -vvv (and not just plain vvv). And next time you report computer output kindly enclose it within code tags <c>

        I am sorry for the bad tag. Here are the debug with -vvv
