ruby - Net::SSH sudo command hangs after entering password -

-

I am trying to write a small library from Thor to help in preparing new projects and sites quickly I am I've written a small method: 

  def ssh (cmd) net :: SSH.start (server_ip, user, port = & port; port) session. Session | Session.exec cmd end end

Please help me run quick commands on a remote server when needed

The problem is that when I am under pseudo If a command is required to run, then the script seems to be hanging for me, for example when it is executed ... 

  ssh ("sudo cp # {file_from_path} # {file_to_path} ")

script for me a password 

  [sudo] password for user:

but then completelyAfter typing it from hhangs

Know that this is hanging at all, and what can I do to run the sudo command on a remote server under Net :: SSH (or some optional)?

* Note: Prior to the suggestion, I had started writing basically until I came to Thor, by this library as a recipe under Capstrano, and thought it was There will be a good chance of trying out. I do not need to switch to Capistrano if back to the whole thing but I would just really be surprised if there is not an easy way to run sudo commands on a remote server.

The first thing you can try is to use a public key instead of a password to log in Still try to run commands from interactive shell. For example:

(This part actually depends on the server / client software) 

  $ ssh-keygen $ scp .ssh / id-dsa.pub Server: $ ssh server server $ cat id-dsa.pub & gt; & Gt; .ssh / authorizedkeys $ scp -c "ls"

This should work without any indication, if the main share was successful.

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
