I noticed how I could freely use ftp or ssh so I'm using a couple of "header distorcing proxies" to bypass the filter: one application runs on the pc i'm using at school increasing by one the value of each letter of the first word in the headers ( HTTP -> IUUQ ) and then passing the stream to a remote proxy which shifts the header back ( IUUQ -> HTTP ). The reverse is done for incoming responses. What do you think about this? Every feedback is welcomed!!

UltraSurf It´s very usefull when the objectve is to avoid proxy restrictions of urls and you dont have much time to do it yourself.

There are indeed a myriad of ways. Some others worth mentioning: <ul> <li>Web-Enabled RSS (Google Reader, yahoo pipes, etc)</li> <li>Out-of-band (EV-DO, Neighboring WiFi, etc)</li> <li>Web-Enabled Anonymizers (PHP Proxy, Megaproxy)</li> <li>Wide-open public proxies on Port 80 (e-pr0xy.com for lists of these)</li> <li>Tunneling (SSH, ICMP, SSL/HTTP)</li> </ul> Indeed, it's quite hard to keep people from accessing content that they really, really want to access. Good write-up. I threw together a 5-part series on bypassing web filters, and I missed some of these. There are indeed a myriad of ways. Some others worth mentioning:

  • Web-Enabled RSS (Google Reader, yahoo pipes, etc)
  • Out-of-band (EV-DO, Neighboring WiFi, etc)
  • Web-Enabled Anonymizers (PHP Proxy, Megaproxy)
  • Wide-open public proxies on Port 80 (e-pr0xy.com for lists of these)
  • Tunneling (SSH, ICMP, SSL/HTTP)

Indeed, it’s quite hard to keep people from accessing content that they really, really want to access. Good write-up.
