Roger has done that + already: + http://sourceforge.net/project/showfiles.php?group_id=75211&package_id=113804 + +you really should upgrade to python 2.3. laziness is no excuse! :) + +some python distributions don't include the utf-8 string encodings, for +reasons of space (misdirected as that is). if your distribution is +missing encodings, you'll see an error like this:: + + LookupError: no codec search functions registered: can't find encoding + +this means you need to copy string encodings over from a working system. +(it probably only happens on embedded systems, not normal python +installs.) Valeriy Pogrebitskiy says the best place to look is +``.../lib/python*/encodings/__init__.py``. + + +Bugs & Support +-------------- + +there's a launchpage page for paramiko, with a bug tracker: + + https://launchpad.net/paramiko/ + +this is the primary place to file and browse bug reports. + +there's also a low-traffic mailing list for support and discussions: + + http://www.lag.net/mailman/listinfo/paramiko + + +Demo +---- + +several demo scripts come with paramiko to demonstrate how to use it. +probably the simplest demo of all is this:: + + import paramiko, base64 + key = paramiko.RSAKey(data=base64.decodestring('AAA...')) + client = paramiko.SSHClient() + client.get_host_keys().add('ssh.example.com', 'ssh-rsa', key) + client.connect('ssh.example.com', username='strongbad', password='thecheat') + stdin, stdout, stderr = client.exec_command('ls') + for line in stdout: + print '... ' + line.strip('\n') + client.close() + +...which prints out the results of executing ``ls`` on a remote server. +(the host key 'AAA...' should of course be replaced by the actual base64 +encoding of the host key. if you skip host key verification, the +connection is not secure!) + +the following example scripts (in demos/) get progressively more detailed: + +:demo_simple.py: + calls invoke_shell() and emulates a terminal/tty through which you can + execute commands interactively on a remote server. think of it as a + poor man's ssh command-line client. + +:demo.py: + same as demo_simple.py, but allows you to authenticiate using a + private key, attempts to use an SSH-agent if present, and uses the long + form of some of the API calls. + +:forward.py: + command-line script to set up port-forwarding across an ssh transport. + (requires python 2.3.) + +:demo_sftp.py: + opens an sftp session and does a few simple file operations. + +:demo_server.py: + an ssh server that listens on port 2200 and accepts a login for + 'robey' (password 'foo'), and pretends to be a BBS. meant to be a + very simple demo of writing an ssh server. + + +Use +--- + +the demo scripts are probably the best example of how to use this package. +there is also a lot of documentation, generated with epydoc, in the doc/ +folder. point your browser there. seriously, do it. mad props to +epydoc, which actually motivated me to write more documentation than i +ever would have before. + +there are also unit tests here:: + + $ python ./test.py + +which will verify that most of the core components are working correctly.
