[opensuse] a very weird WiFi/HTTPS combo bug
Hello fellow linuxers, Here's a really strange one. I have at least two ZIP files (here's a link to one: https://zoomwhee.mgh.harvard.edu/~bepstein/photo.zip ) which a OpenSuSE 11.1 machine can download without a glitch over a wired connection to a router, yet fails to download over a WiFi through the same router. One more machine (an OpenSuSE 11.0 one) fails to download it over WiFi. Download over a wired connection goes flawlessly on multiple machines. So does a download over regular HTTP (not available to the world). Any idea why this would be? I am totally puzzled. Thanks.

I personally can't even download it on IE6 from my company's T1 Network with no website and file and etc. blocking... Wish I could install SUSE on my company PC... Seems as if you're file doesn't really go well at alll...

Thanks again, Allen! I just tried on a WiFi connected 11.0 machine at home, and both the GIF and the ZIP file transfer fine over HTTP. The GIF file goes fine over HTTPS, but the ZIP does not. And the question remains: why????? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Install Wireshark, if you haven't already, and use it to monitor the transfer. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Try the following: Change the MTU on the WiFi interface on the PC to 1492. Rudolf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Watch out for fragmentation issues caused by incompatible MTU settings on your WiFi interface and your router. Ingolf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

While fragmentation might cause a slow down, it shouldn't kill the transfer. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I agree with you on that - this is how things should be. However, I just changed the MTU to 1024 on one of the WiFi routers involved and that seems to have fixed the problem. So maybe it was indeed the fragmentation. Boris. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
