ping problems
hi i have an openwrt (linux) router, with regular firewall rules (nat, related+established,clamp-mss-to-pmtu, etc). if i ping from the router to the internet, it works ok however if i ping from inside my lan to the internet, the first 30-70 pings works, then it stops working (i.e. 100% packet lost after the first 30-70) using tcpdump inside my router shows the icmps going through the wan interface but none come back. any idea ? erez. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: ping problems
If you ping another destination during the hang - does it work? If you ifdown and ifup the interfaces (wan + lan) on the router after a hang - is it released? an icmp packet is short so i don't think this is the case but: what is the MTU on the lan/wan? Also, use a tool like mtr http://en.wikipedia.org/wiki/Mtr_(My_traceroute) to detect any packet loss along the route. 2009/5/27 Erez D erez0...@gmail.com: hi i have an openwrt (linux) router, with regular firewall rules (nat, related+established,clamp-mss-to-pmtu, etc). if i ping from the router to the internet, it works ok however if i ping from inside my lan to the internet, the first 30-70 pings works, then it stops working (i.e. 100% packet lost after the first 30-70) using tcpdump inside my router shows the icmps going through the wan interface but none come back. any idea ? erez. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il -- Frank Lloyd Wright - TV is chewing gum for the eyes. - http://www.brainyquote.com/quotes/authors/f/frank_lloyd_wright.html ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Re: ping problems
Try netstat -s to checks for errors/drops on the WAN interface. Anything interesting? If a ping from the router always succeeds, and after some time fails from the lan AND during failure you see the packets go from the lan out to the wan but doesn't come back at all - it sounds like something is wrong with the outgoing ping request packet. Did you see any difference between a goog ping and bad ping packets?

Internet Customer Service
Hi all, First, apologies to those on the other lists I'm posting this to. I'm so excited I had to tell everyone :) It appears that someone somewhere is listening to what we need, and doing something about it. This morning I had a local customer who is not technically inclined enough to set up their own VoIP router, so I went over there to do it for them. They are an older couple with an older PC and no real idea how it all works. Their adult son had set them up and is out of the country at the moment. So I went there, together we phoned their ISP, 012, to tell them we were installing a new router. The tech on their end said to set the router to Obtain IP address automatically, and call HOT with the confirmation number they gave us, in order to change to an account that doesn't need a dialer. We phoned HOT, gave them the confirmation number, and it just worked. This is a HUGE change from a few years ago, when I had to call and explain to the customer service rep what I wanted to do, who couldn't imagine why anyone would need an account without a dialer. Then I had to wait a week for HOT to set up MPLS, and spend hours and hours on the phone with level after level of customer support and technicians to make sure it actually got done. Israel has entered the modern age! Yay! I realize this isn't directly linux-related, but it's certainly relevant to those of us not running windows and our ability to get what we need from the service providers who've locked us out in the past. --sambo ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

I also spent around 10 hours on the phone with HOT and barak, separately and together, about 3 years ago to get a dialer-less connection. I think their internal integration system simply sucked. Last year, moving to bezeqint, it only took 3 days, and a couple of hours on the phone. Good to know they continued to improve since then :) --y ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Re: Internet Customer Service
Hi, I found that even with Bezeq Beinleumi, which were giving non dialer account, I needed to spend 3 days barking on Hot and them. Hope I will have your experience next time.
