Re: Walla mail from Linux - Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.
OK, sorry everyone - false alarm - apparently not a Linux issue. _ However, if I've already started, maybe someone can help me out with a similiar problem which I know is linux related - I checked. If I access http://www.jobnet.co.il/ from firefox on Linux, I get some or none of the graphics (looks like I get all the text). From firefox on Windows - I get everything. Sometime, if I reload the page many times, I get more of the graphics. Sometimes when I reload I actually get less. If I go to http://www.jobnet.co.il/SearchIndex.aspx from Chrome, I get: No data received Unable to load the webpage because the server sent no data. Here are some suggestions: Reload this webpage later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. Any ideas ??

I stopped raising a brow, just hit the try again button. It never occurred to me to suspect Linux (this looks to me a Google-specific issue) - I thought those were glitches in Google's massive datacenters... Or maybe in some Israeli cache or whatever. o...@goldshmidt.org One other possibly related consideration (even though I have no indication that it is relevant): I use things like Ghostery and also map a lot of dodgy domains to localhost in /etc/hosts - I thought that maybe some snoopy servers (like Google's?) occasionally react in weird ways if they can't find the expected cookies or don't get a nod from some tracker/analytics engine or whatever? -- Oleg Goldshmidt | p...@goldshmidt.org o...@goldshmidt.org ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

More likely than a Linux's fault, is faulty routers (or appliances) on your path to Google's servers, that think they're smarter than Internet endpoints, instead of just... routing traffic, what they were originally supposed to do. Sometimes it's those smart QoS boxes... Recently I did a very long debugging session on a customer of Netvision/Barak, and realized that their equipment doesn't like the advanced features enabled by Linux by default - the behavior of the ISP network changed as I modified the things below. I would start echoing 0 to numerous stuff under /proc/sys/net/ipv4/* to see if the problem alleviates. Start with disabling: TCP Timestamps TCP SYN Cookies Window Scaling Selective ACKs (SACKs) Also try MTU @ 1300 for the fun And if you have TCP Offloading... might want to disable that, too. It could be your NIC / NIC driver. Good luck :-) -- Shimi ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
