Then, remove it again or reboot your computer. + + Unpack the tarball : + # tar vjxf r8169-6.aaa.bb.tar.bz2 + + Change to the directory: + # cd r8169-6.aaa.bb + + If you are running the target kernel, then you should be able to do : + + # make clean modules (as root or with sudo) + # make install + # depmod -a + # modprobe r8169 + + You can check whether the driver is loaded by using following commands. + + # lsmod | grep r8169 + # ifconfig -a + + If there is a device name, ethX, shown on the monitor, the linux + driver is loaded. Then, you can use the following command to activate + the ethX. + + # ifconfig ethX up + + , where X=0,1,2,... + + +<Set the network related information> + 1. Set manually + a. Set the IP address of your machine. + + # ifconfig ethX "the IP address of your machine" + + b. Set the IP address of DNS. + + Insert the following configuration in /etc/resolv.conf. + + nameserver "the IP address of DNS" + + c.

Set by doing configurations in /etc/sysconfig/network-scripts + /ifcfg-ethX for Redhat and Fedora, or /etc/sysconfig/network + /ifcfg-ethX for SuSE.

DHCP: + DEVICE=eth0 + BOOTPROTO=dhcp + ONBOOT=yes + +<Change the MAC address> + There are two ways to modify the MAC address of the NIC. + 1. Use ifconfig: + + # ifconfig ethX hw ether YY:YY:YY:YY:YY:YY + + , where X is the device number assigned by Linux kernel, and + YY:YY:YY:YY:YY:YY is the MAC address assigned by the user. + + 2.

Force the link status when insert the driver. + + If the user is in the path ~/r8169, the link status can be forced + to one of the 5 modes as following command. + + # insmod ./src/r8169.ko speed=SPEED_MODE duplex=DUPLEX_MODE autoneg=NWAY_OPTION + + , where + SPEED_MODE = 1000 for 1000Mbps + = 100 for 100Mbps + = 10 for 10Mbps + DUPLEX_MODE = 0 for half-duplex + = 1 for full-duplex + NWAY_OPTION = 0 for auto-negotiation off (true force) + = 1 for auto-negotiation on (nway force) + For example: + + # insmod ./src/r8169.ko speed=100 duplex=0 autoneg=0 + + will force PHY to operate in 100Mpbs Half-duplex(nway force). + + 2. Force the link status by using ethtool. + a. Insert the driver first. + b. Make sure that ethtool exists in /sbin. + c. Force the link status as the following command. + + # ethtool -s ethX speed SPEED_MODE duplex DUPLEX_MODE autoneg NWAY_OPTION + + , where + SPEED_MODE = 1000 for 1000Mbps + = 100 for 100Mbps + = 10 for 10Mbps + DUPLEX_MODE = half for half-duplex + = full for full-duplex + NWAY_OPTION = off for auto-negotiation off (true force) + = on for auto-negotiation on (nway force) + + For example: + + # ethtool -s eth0 speed 100 duplex full autoneg on + + will force PHY to operate in 100Mpbs Full-duplex(nway force). + +<Jumbo Frame> + Transmitting Jumbo Frames, whose packet size is bigger than 1500 bytes, please change mtu by the following command. + + # ifconfig ethX mtu MTU + + , where X=0,1,2,..., and MTU is configured by user.
