How to reboot your bebox using the CLI
######################################

:date: 2010-10-21

I've an internet connection which, for some obscure reasons, tend to be very
slow from time to time. After rebooting the box (yes, that's a hard solution),
all the things seems to go fine again.

EDIT : Using grep
=================

After a bit of reflexion, that's also really easy to do using directly the
command line tools curl, grep and tail (but really harder to read).

.. code-block:: bash

   curl -X POST -u joel:joel http://bebox.config/cgi/b/info/restart/\?be\=0\&l0\=1\&l1\=0\&tid\=RESTART -d "0=17&2=`curl -u joel:joel http://bebox.config/cgi/b/info/restart/\?be\=0\&l0\=1\&l1\=0\&tid\=RESTART | grep -o "name='2' value='[0-9]\+" | grep -o "[0-9]\+" | tail -n 1`&1"

The Python version
==================

Well, that's not the optimal solution, that's a bit "gruik", but it works.

.. code-block:: python

    import urllib2
    import urlparse
    import re
    import argparse

    REBOOT_URL = '/b/info/restart/?be=0&l0=1&l1=0&tid=RESTART'
    BOX_URL = 'http://bebox.config/cgi'

    def open_url(url, username, password):
        passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
        passman.add_password(None, url, username, password)
        authhandler = urllib2.HTTPBasicAuthHandler(passman)

        opener = urllib2.build_opener(authhandler)

        urllib2.install_opener(opener)

        return urllib2.urlopen(url).read()

    def reboot(url, username, password):
        data = open_url(url, username, password)
        token = re.findall("name\=\\'2\\' value=\\'([0-9]+)\\'", data)[1]
        urllib2.urlopen(urllib2.Request(url=url, data='0=17&2=%s&1' % token))

    if __file__ == '__main__':
        parser = argparse.ArgumentParser(description="""Reboot your bebox !""")

        parser.add_argument(dest='user', help='username')
        parser.add_argument(dest='password', help='password')
        parser.add_argument(boxurl='boxurl', default=BOX_URL, help='Base box url.  Default is %s' % BOX_URL)

        args = parser.parse_args()
        url = urlparse.urljoin(args.boxurl, REBOOT_URL)
        reboot(url, args.username, args.password)
