If you use Deluge as a preferred application for torrents, you might be in need at some point to trick client identification to tracker, in order to still connect to those trackers who have a “whitelist” applications (without Deluge, of course :) )
Because Deluge is a python application, the modifications can be done on the fly, very easily using a simple text editor.
Identify core.py for deluge (now version 1.2). This is in ubuntu distro at /usr/lib/pymodules/python2.6/deluge/core/core.py for example.
class Core(component.Component): def __init__(self, listen_interface=None): ... version = [3, 1, 1, 0] # this line is added ##self.session = lt.session(lt.fingerprint("DE", *version), flags=0) # this is commented out self.session = lt.session(lt.fingerprint("AZ", *version), flags=0) # this identifies our Deluge as Azureus 22.214.171.124 # Set the user agent self.settings = lt.session_settings() ##self.settings.user_agent = "Deluge %s" % deluge.common.get_version() # this is commented out self.settings.user_agent = "Azureus 126.96.36.199" # # this identifies our Deluge as Azureus 188.8.131.52
