in thread Probelm getting a large compressed tar file over ssh.

You don't really need a trusted host relationship, you just need passwordless keys. If passwordless keys are impossible, then you will have to use the interactive method. Maybe you can go forward by hacking Net::Ssh::Perl to redirect the STDOUT part of the connection. Looking into the source of Net::SSH::Perl::SSH1, there seem to be handlers like SSH_SMSG_STDOUT_DATA and replacing the default handler with something that doesn't accumulate the string might help:

# Original code sub cmd { ... unless ($ssh->handler_for(SSH_SMSG_STDOUT_DATA)) { $ssh->register_handler(SSH_SMSG_STDOUT_DATA, sub { $ssh->{_cmd_stdout} .= $_[1]->get_str }); } ... }

I would try to supply my own callback like this:

my $ssh = Net::SSH::Perl->new(...); open my $outfh, ">", $filename or die "Couldn't create '$filename' : $!"; binmode $outfh; $ssh->register_handler('stdout', sub { print $outfh $_[1]; });

    If passwordless keys are at all possible, you could also consider File::Remote.

    This is from the example:

    use File::Remote qw(:replace); # read from a remote file open(REMOTE, "host:/remote/file") or die $!; print while (<REMOTE>); close(REMOTE); # writing a local file still works! open(LOCAL, ">>/local/file"); print LOCAL "This is a new line.\n"; close(LOCAL); # Read and write whole files my @file = $remote->readfile("host:/remote/file"); $remote->writefile("/local/file", @file);
