    <p>I'm pretty new to Python and programming. I'm trying to copy a file between two computers via a python script. However the code</p> <pre><code>os.system("ssh " + hostname + " scp " + filepath + " " + user + "@" + localhost + ":" cwd) </code></pre> <p>won't work. I think it needs a password, as descriped in <a href="https://stackoverflow.com/questions/68335/how-do-i-copy-a-file-to-a-remote-server-in-python-using-scp-or-ssh">How to copy a file to a remote server in Python using SCP or SSH?</a>. I didn't get any error logs, the file just won't show in my current working directory.</p> <p>However every other command with <code>os.system("ssh " + hostname + "command")</code> or <code>os.popen("ssh " + hostname + "command")</code> does work. -> <code>command = e.g. ls</code></p> <p>When I try <code>ssh hostname scp file user@local:directory</code> in the commandline it works without entering a password.</p> <p>I tried to combine <code>os.popen</code> commands with getpass and pxssh module to establish a ssh connection to the remote server and use it to send commands directly (I only tested it for an easy command):</p> <pre><code>import pxssh import getpass ssh = pxssh.pxssh() ssh.force_password = True hostname = raw_input("Hostname: ") user = raw_input("Username: ") password = getpass.getpass("Password: ") ssh.login(hostname, user, password) test = os.popen("hostname") print test </code></pre> <p>But I'm not able to put commands through to the remote server (<code>print test</code> shows, that hostname = local and not the remote server), however I'm sure, the conection is established. I thought it would be easier to establish a connection than always use <code>"ssh " + hostname</code> in the bash commands. I also tried some of the workarounds in <a href="https://stackoverflow.com/questions/68335/how-do-i-copy-a-file-to-a-remote-server-in-python-using-scp-or-ssh">How to copy a file to a remote server in Python using SCP or SSH?</a>, but I must admit due to lack of expirience I didn't get them to work.</p> <p>Thanks a lot for helping me.</p>

    1. COWhy do you think you need to do `ssh hostname scp`? Why not just `scp user@hostname:file localdirectory`?

    2. COPrefer the `subprocess` module over `os.system()` for security reasons.

    3. COI haven't thought about the posibility to copy via `scp user@hostname:file localdirectory`. It does work, but only when I cancel the `user@` part.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
