    full duplex, speed in graphical mode

    Hello!

    I have the Fedora 10.
    My question concern network card.
    Haw to set "full duplex" or "speed 100" in graphical mode?
    I know in the text mode there is ethtool, but I have some problem with it.
    I have to make ifdown, ifup, and activate device.
    So, I would like to make it in caraphical mode. I think it would be easier.

    It appears you can't.

    But not to worry! What you want to do is edit the file /etc/sysconfig/network-scripts/ifcfg-eth0, then add a line ETHTOOL_OPTS.

    For example, the file should look a bit like:

    Code:
    DEVICE=eth0
    BOOTPROTO=none
    HWADDR=00:1d:60:a6:75:d5
    ONBOOT=yes
    NM_CONTROLLED=no
    TYPE=Ethernet
    ETHTOOL_OPTS="speed 100 duplex full autoneg off"
    IPADDR=1.2.3.4
    NETMASK=255.255.255.0
    GATEWAY=1.2.3.1
    Most of this file should have been filled in by the graphical utility. You only need to add the ETHTOOL_OPTS line.

    i don't think i've ever come across a linux distro or switch combination that reacts well to "duplex full autoneg off", for some reason it always seems to negotiate full duplex and the fastest speed if i don't set them, but if i do it always gets it wrong or won't bring up the interface.

    works fine on solaris, in fact you pretty much have to force things in solaris.

    and as for a gui to handle ethtool, its one command and once its set it doesn't seem to need to be set again, i guess it saves it in the nic/switch nvram or something.
