Re: what can be done against isp blocking ports
Hi Gil OMG, I can't believe what I am hearing. You had to ask her which kind of electronic chip you have to insert in the pc. Just to bend her on knees. It reminds me of the BOFH (bastard operator from hell) jokes. http://bofh.ntk.net/Bastard.html Try it sometimes if you want to get a really good laugh. The first chapters are fantastic. The sad thing is that I work without firewall and I still get stardust. ;-( On 3/30/08, Gil Freund [EMAIL PROTECTED] wrote: On Sun, Mar 30, 2008 at 1:25 AM, sammy ominsky [EMAIL PROTECTED] wrote: On 30/03/2008, at 00:14, Gil Freund wrote: My two recent favorites from an ISP support tech: 1.

Re: what can be done against isp blocking ports
Hi everyone, I've been following this thread with great interest. As a relative newcomer to Israel (I've been here 11 months), I'm only vaguely aware of some of the most prominent ISPs. I'm also aware that a few of them have murged recently. No-one here really seems to like any of the big ones much by the looks of things. My wife and I are currently on contract through Hot and Barak. But our contract will be up in a few weeks. So we're ISP shopping and I'd be interested in recommendations for the best (or least worst) ISPs.

We used IBM until they sold their network to ATT and eventually stopped accepting Israeli credit cards. Service is good, the connection is reasonably reliable and fast. They do not block or limit bit torrent, I've occasionaly gotten over 300k bytes per second download. With FTP or HTTP, I see often as much as 400k bytes per second.

My firewall is disabled. And I am connected through the modem only. Yet only 1 port is open. Exactly how do you connect to them? By law in Israel, bot BEZEQ and HOT can not connect you to the Internet. They can only connect you to a licensed ISP. In order to get around that, you connect to your ISP using a VPN. (Virtual private network). In Linux terms, it's over a tunnel. If you have a cable modem and a willing ISP, you don't need a tunnel, because HOT can route all of your packets to your ISP. AFAIK, they no longer will do this for new customers, or old ones that want to change. The most common way of connecting to an ISP over an aDSL line is via an L2TP tunnel with a Windows computer being at your end of the tunnel. Other protocols such as PPOA and PPOE are also used. The easiest way to handle it IMHO is for the small user to buy a cheap router and let it handle the tunneling. I started out with a Pentium 133 as my router when I got a cable modem a long time ago, and have long since upgraded it. It's not as easy to maintain, but it gives me more flexibility. BEZEQ has some deal where you can get a wireless router from them, with support, for around 10NIS a month, if you commit to two years. If you are interested don't ask me for details, but please post what you find out. What can I do in this case? Proxy client, server on the pc? Use proxy from the internet? Port forward? Besides browsing I need the p2p. I was faced with a similar situation accessing a local government website in the U.S. For some silly reason, they blocked access to it from overseas. Their sysadmin must have been on the mailing list I asked for advice in a week or two it was fixed. :-) Meanwhile I found out that you can run SSH as a remote SOCKS proxy. If you can access a system somewhere else with SSH, and they let you, it's a way of accessing sites blocked to you. For FireFox there is an add-on called foxyproxy, which picks the proxy based upon the URL, and for windows there is a public domain SOCKS tunnel. I have not seen one for Linux, only programs modified to use SOCKS. If anyone can add anything, I would appriciate it. Geoff. -- Geoffrey S.

Re: what can be done against isp blocking ports
Thanks Maxim. They were OK in the begining. And what about the following things: 1. Change ports, like 6 something random? 2. Encryption I can do in ftp. 3. Some kind of tunneling that traffic will be recognized as legit http. 4. Proxy? I also have a linksys router. When I experienced the packet loss it was on a hot server. adsl gives support to linux? The only thing is that adsl is much more expensive. what p2p work with encryption? I mainly use dc++.
