# o Enable CookieAuthentication (CookieAuthentication 1 in torrc) or define a HashedControlPassword

# user debian-tor
# env.cookiefile /var/run/tor/control.authcookie

# Parameters understood (defined in file /etc/munin/plugin-conf.d/munin-node or in environment)
# host - Change which host to graph (default localhost)
# port - Change which port to connect to (default 9051)
# host - Change which host to graph (default localhost)
# port - Change which port to connect to (default 9051)
# password - Plain-text control channel password (see torrc
# HashedControlPassword parameter)
# HashedControlPassword parameter)
# cookiefile - Name of the file containing the control channel cookie
# (see torrc CookieAuthentication parameter)
# (see torrc CookieAuthentication parameter)
#
# Using HashedControlPassword authentication has the problem that you must
# include the plain-text password in the munin config file. To have any
# effect, that file shouldn't be world-readable.
# If you're using CookieAuthentication, you should run this plugin as a user
# which has read access to the tor datafiles. Also note that bugs in versions
# upto and including 0.1.1.20 prevent CookieAuthentication from working.

# Usage: place in /etc/munin/node.d/ or in /etc/munin/plugins (or link it there using ln -s)
