dont use normal proxies... they only rewrite partial bits.... to name just one flaw in your system..... use systems that are tried+tested for this task... ones that even check your outgoing http headers for sensitive data... IE: privoxy
...ok ok ok....well admitadly i had to spend weeks of reading, testing ohh.. and more reading to learn this..... lemme disseminate some info for u guys (if indeed u wanna do things right)....
You know your IP/proxy will get sh1t listed if u over do it and dont actually anonymize the traffic?
There are sollutions... but they dont come pre-installed with guis.....
Squid + at least 8 tors talking into it + privoxy to ensure your not leaking important/secret data (IE: YOUR TRACEABLE IPS!)
Privoxy is the key.... squid... like and octopus has a tenticle going to each tor... its kinda complex at first but once u set up the first functional tentacle its pretty much copy/paste, change a few ports, ad new init script for next instance...... go google it for details.
I'll help you do it if u like with general advice, but best it to actually understand what you are doing and read documentation... dont get your damn dedi's IP blacklisted [DOH], particularly cause whats the point of all this when they can trace who owns that IP/who owns site beeing buffed? ohhh... funny.. those names seem similar hmmmm......
Another tip....u can rent VPS's specifcly for seeding (IE: p2p traffic/tor)
Tor is a slow beast.. even on a dedi... running more VIA squid means instead of ppl seeing your http spam or whatever coming from a certain IP for say 3-5 minutes (which is what tor does, watch a tcpdump/wireshark) Using multiple tors just mashes things up... brilliant .... ohh and even then its still not 100% secure, but u can do the math its _way_ better.... tho if yer hosting it can slow down some services... all depends
but i have unlimited bandwidth so if u have B/W consciderations well.... might wanna read some forums on tor anyway.... call me paranoid but its worth it doing your homework! -and good luck
did someone say light proxy btw? *cough* nginx *cough* its like sendmail vs qmail
/me checks his tin-foil hat is secure
