[opensuse] loosing packages
Hi, I have a machine on my network that started to drop an exorbitant amount of packages, in access of 20%. Running openSUSE 11.3 on i586, latest kernel update 2.6.34.7-0.7-default #1 SMP 2010-12-13 11:13:53 +0100 i686 i686 i386 GNU/Linux I observed the behavior with both a wired and wireless connection (wired used Ethernet over power line). There are no messages in the kernel log, no processes pegging the CPU, i.e. other than the network traffic the machine appears to be in good shape. How can I figure out where and why my packages are getting dropped. firewall is disabled.

Hi Robert, Without be sarcastic, one might say that it is the price for being flexible. With regards to wireless connections, it might be the case that you share your channel with 30 other people? You know that in the 2.4GHz band, there are only three non-overlapping channels... This is getting worse and worse... With regards to powerline, It is very susseptible to noise. LAN-Powerlines radiate a lot, and pickup a lot. (engines, oven's) It is not without reason that these devices are forbidden in some countries, because of the RF-pollution they cause. Furthermore, if you are on a different power group (RST-phase) you will have no connection at all. I can just suggest cat5, cat6 or fiber. hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks, Robert
I am assuming you mean "packets" as in network packets, otherwise your question doesn't make sense (is the German word the same for package and packet?) First step would be to isolate hardware vs software - since you say its happening on both wired and wireless NICs, its likely either in the software on your machine, or an ISP problem beyond your router. Do other machines on your network have the same problem? Does a liveCD on the affected machine have the same problem?
