It has two modes of operation: UID based -# and IP based. - -# UID BASED PRIORITIZATION -# -# The UID based method requires that Tor be launched from -# a specific user ID. The "User" Tor config setting is -# insufficient, as it sets the UID after the socket is created. -# Here is a C wrapper you can use to execute Tor and drop privs before -# it creates any sockets. -# -# Compile with: -# gcc -DUID=`id -u tor` -DGID=`id -g tor` tor_wrap.c -o tor_wrap -# -# #include -# int main(int argc, char **argv) { -# if(initgroups("tor", GID) == -1) { perror("initgroups"); return 1; } -# if(setresgid(GID, GID, GID) == -1) { perror("setresgid"); return 1; } -# if(setresuid(UID, UID, UID) == -1) { perror("setresuid"); return 1; } -# execl("/bin/tor", "/bin/tor", "-f", "/etc/tor/torrc", NULL); -# perror("execl"); return 1; -# } - -# IP BASED PRIORITIZATION -# -# The IP setting requires that a separate IP address be dedicated to Tor. -# Your Torrc should be set to bind to this IP for "OutboundBindAddress", -# "ListenAddress", and "Address". - -# GENERAL USAGE -# -# You should also tune the individual connection rate parameters below -# to your individual connection. In particular, you should leave *some* -# minimum amount of bandwidth for Tor, so that Tor users are not -# completely choked out when you use your server's bandwidth. 30% is -# probably a reasonable choice. More is better of course. -# -# To start the shaping, run it as: -# ./linux-tor-prio.sh -# -# To get status information (useful to verify packets are getting marked -# and prioritized), run: -# ./linux-tor-prio.sh status -# -# And to stop prioritization: -# ./linux-tor-prio.sh stop -# -######################################################################## - -# BEGIN USER TUNABLE PARAMETERS - -DEV=eth0 - -# NOTE!
