[Perl][net::ssh2] How to keep the ssh connection while executing remote command

Question

I'm working on a perl script using net::ssh2 to make a SSH connection to a remote server. (I'm working on windows) I chose Net::SSH2 because i had to make some SFTP connections in the same script. For now, my sftp connections work perfectly. The problem is when i try to execute a "long-duration" command. I mean a command which execution can take more than 30sec. ``` $ssh2 = Net::SSH2->new(); $ssh2->connect('HOST') or die; if($ssh2->auth(username=>'USER', password=>'PSWD')) { $sftp = Net::SFTP::Foreign->new(ssh2=>$ssh2, backend=>'Net_SSH2'); $sftp->put('local_path', 'remote_path'); $channel=$ssh2->channel(); ## $channel->shell('BCP_COMMAND_OR_OTHER_PERL_SCRIPT'); # OR (I tried both, both failed :( ) $channel->exec('BCP_COMMAND_OR_OTHER_PERL_SCRIPT'); ## $channel->wait_closed(); $channel->close(); print "End of command"; $sftp_disconnect(); } $ssh2->disconnect(); ``` When i execute this script, the connection is successfull, the file is correctly sent but the execution is not (completel…

You can try using Net::SSH::Any instead.

It provides a higher level and easier to use API and can use Net::SSH2 or Net::OpenSSH to handle the SSH connection.

For instance:

```
use Net::SSH::Any;

my $ssh = Net::SSH::Any->new($host, user => $user, password => $password);
$ssh->error and die $ssh->error;

my $sftp = $ssh->sftp;
$sftp->put('local_path', 'remote_path');

my $output = $ssh->capture($cmd);
print "command $cmd output:
$output

";

$sftp->put('local_path1', 'remote_path1');

# no need to explicitly disconnect, connections will be closed when
# both $sftp and $ssh go out of scope.
```

Note that SFTP support (via Net::SFTP::Foreign) has been added on version 0.03 that I have just uploaded to CPAN.
