There is nothing currently to do about this, the correct technical term for what 012 are doing is "Deep Packet Inspection". They are probably using something like [1] to QOS p2p traffic. They are not blocking ports, they are reading the content of your traffic and analyzing it in real time, these packets that are labeled as "low priority get Throttled. I'm also connected to 012 using HOT, for the last 3 months I'm experiencing an ever degrading performance of popular file sharing protocols such as ed2k and bit torrent. It get's to such ridicules rates as 3KB/s. I can verify this is an ISP issue, because : a. I've made an experiment with my fellow college where we started downloading the same popular file, each from his own home simultaneously. He is connected via Bezeq+ADSL and I'm through 012+HOT. My download rate was 6Kb/s (max) while his maintained an steady rate of 55Kb/s. We're both connected using a Linksys Router, and made proper checking before started the test: Ports have been forwarded and verified to be allow connect(), other network devices have been disconnected. No other downloads / uploads were active. b. I've talked to 2 other friends at work, who are also connected using 012 and are reporting to experience the exact same service disrupts as I am. c. Please read these forum posts, discussing this issue : - http://forum.bgu.co.il/index.php?showtopic=165231&pid=1673953 - http://209.85.135.104/search?q=cache:UV5wN3Sg4rYJ:selectv.net/lofiversion/index.php/t37336.html+012+%D7%97%D7%95%D7%A1%D7%9E%D7%99%D7%9D&hl=en&ct=clnk&cd=9&client=firefox-a We've spoke to 012 representative, it's always the same "automatic" answer they have been instructed to provide: "Problem with your computer, spyware, virus, wrong usage" No point in arguing with the poor technical support guy because he a. Can't help you. B. Probably does not have the slightest clue about what you are talking about. This leads me to the conclusion that nothing can be done besides leaving the company that insists on hurting it's costumers and join Bezeq, who may or may not be the best ISP around but at least they aren't using technology to hide cowardly acts from their users. I for one have lost my faith in 012 completely, I will not let this slip and have already started the procedure of disconnecting from 012 ASAP. I will also make sure all my friends + parents + who ever I can advice on ISP choosing to reconsider their decision based on the above. Maxim. [1] http://www.cyberoam.com/contentfiltering.html p.s. The solution to this "problem" is passing your traffic encrypted, i.e. SSL. The problem here that all traffic then must be TCP which is actually bad for the Operator as it increases the bandwidth usage. -- Cheers, Maxim Veksler "Free as in Freedom" - Do u GNU ? ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
