[opensuse] openSUSE 11 & gigabit
Hello, I just received a gigabit hub. The cable connected to my son's XP computer is green (gigabit), but the one connected to my openSUSE box is yellow (10/100) is there something to do to have gigabit on the Linux box? (network eth, of course, r8169 module, RTL8111/8168B PCI Express Gigabit Ethernet controller the cables are cat 5, so I don't expect full speed, but the XP cable is older and the green light is on :-) quick test: 450Mb/1mn, that is 125Mb/s average thanks jdd -- http://www.dodin.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well, although Cat5e should be better, Cat5 "should" work with Gigabit Ethernet. Also check that you have a full four twisted pairs cable. Could you also place the output of 'ethtool eth0' ? A few clews could be found there. You can also use that tool to try to change the network link mode manually, but generally that is not a recommended method. If you intent to place the output like I suggested you to, please do it before any manual change.
quick test: 450Mb/1mn, that is 125Mb/s average
thanks jdd

tried to set speed 1000 - "ethtool -s eth0 speed 1000", but this don't works better (never give 1000 in the test, cut the connection)
Well, IMHO you have to start eliminating where the problem comes from. Here are some ideas: - You can try with a crossover cable to perform a direct test with your XP machine. If it works at GBit, then your openSUSE machine is most certainly OK. - Connect the openSUSE 11.0 network cable to the same switch port that your XP machine is connected at ( temporarily disable you XP machine ). If it connects at GBit, it could be a switch port problem ( on the other one, of course... ). - If both fail to connect at GBit, then your problem is probably more esoteric. Please report your tests...

you got it! this is a switch port problem, on an other port it connect with 1000Mb thanks! jdd -- Jean-Daniel Dodin Président du CULTe www.culte.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

tried with a gigabit verified cable: not better thanks jdd -- Jean-Daniel Dodin Président du CULTe www.culte.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The negotiation between your network card and the switch might result in 100 Mbps even though they both can do 1 Gbps. Such incompatibilities happen rarely. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
