    RTNETLINK answers: no such process

    OK this has me stumped

    Recently updated my fedora 10 box with latest updates via Yum as well as installing a 1GB Switch

    it has 2 NICs - eth0 (Staff) and eth1 (Pupils)

    When it brings up eth0 I get the following message

    Code:
    RTNETLINK answers: no such process
    eth0 appears to start with [OK]

    however, I cannot ping the server or ping out using eth0 - Destination Host unreachable

    I have checked the configs in /etc/sysconfig/network-scripts/ifcfg-staff_lan and it is identical to the config for the eth1 port (save for the IP addreses)

    Eth0 config:
    Code:
    DEVICE=eth0
    BOOTPROTO=none
    BROADCAST=10.4.25.255
    HWADDR=00:18:71:78:68:B6
    IPADDR=10.4.24.236
    NETMASK=255.255.254.0
    NETWORK=10.4.24.0
    GATEWAY=10.4.24.255
    ONBOOT=yes
    DNS1=10.4.24.200
    SEARCH="staff.internal"
    NM_CONTROLLED=no
    TYPE=Ethernet
    USERCTL=no
    IPV6INIT=no
    Eth1 Config:
    Code:
    DEVICE=eth1
    BOOTPROTO=none
    BROADCAST=192.168.255.255
    HWADDR=00:18:71:78:68:B4
    IPADDR=192.168.0.100
    NETMASK=255.255.0.0
    NETWORK=192.168.0.0
    ONBOOT=yes
    DNS1=192.168.0.200
    SEARCH="pupils.moorsdie.internal"
    NM_CONTROLLED=no
    TYPE=Ethernet
    USERCTL=no
    IPV6INIT=no
    Dunno why Eth1 is working but eth0 is not

    Im abit confussed as to why you named it ifcfg-staff_lan, I would of just kept it as eth0

    But a few things to try:

    Rename it to ifcfg-eth0
    then do:

    Code:
    ifup eth0
    Or just try with your current settings...

    Code:
    ifup staff_lan

    Comparing it with my config files it looks right, so the only thing that is jumping to mind is the file name...

    shouldnt the broadcast address be 10.4.255.255

    ?????

    Not sure if that makes any difference but was just something I noticed

    Not sure if its the same as obviously each ethernet adaptor ( network card ) is on a different subnet and noticed the student ethernet one the 192.168.x.x was on a 255.255 broadcast range where as the other one was missing a 5 ie 25.255 instead of 255.255.

    As I said above not sure if it would help or not.

    Look at the syslog when you restart networking to see what is causing the RTNETLINK error

    those kinda of faults at least in my windows experience means that the services were not up and running correctly

    Not sure why linux would do that *shrugs*

    Am guessing a reboot or using the correct commands to restart the services would of done the trick possibly.

    Ok then the other reason you'd get that error is when the kernel is trying to setup a route to somewhere that doesn't exist or effectively duplicates an existing route. Check your routing table(s) with 'route -n'. A common example of this problem is on servers with dual nics. You setup both nics with sensible defaults and you give them both the same gateway address (because they are plugged into the same LAN). You will get the above error when the kernel tries to setup the default route to the default gateway upon initializing the second Ethernet device.
