Problems with DHCP in FC3

    I've just installed FC3 on the second drive of a PC (first drive boots in Windoze). If I manually set up the IP address using the redhat network configuration tool, I can access local IPs OK (i.e. ping them) but cannot resolve URLs becasue I don't have DNS set up (a side question - how to set up DNS manually). If I set up for DHCP and automatic DNS configuration (as I have set up under Windoze), I can't even ping the local IP addresses. IT appears no DHCP address allocation occurs. ifconfig reports "No DHCPOFFERS received".

    FYI - I'm using an SMC Barricade G router, configured to provide DHCP addresses, known to work with this several PCs includign the one in question under Windoze.

    Any help would be appreciated.

    Enough with the "Windoze" already. :rolleyes: I see it as apparently working where Linux is not, which gives it the advantage, no?

    Access your router's configuration page via a browser and you'll see your DNS servers listed there.

    Then enter them manually (remember to disable DHCP), save, restart eth0 and you'll be away.

    Thanks for the quick response.

    OK - no more Windoze remarks :D I'm only a linux Newbie anyway, so its probably far to early to give up the ways of the infidel.

    I tried copying the primary and secondary DNS addresses from my eircom Netopia DSL modem/router, but still no joy (can't resolve www.google.com).

    For me this is an exercise in getting Linux up and running, so while a workaround is of interest, I would really like to get the thing working as advertised, i.e. DHCP with automatic DNS.

    Try these settings in system-config-network:

    Statically set IP addresses.

    192.168.1.1 as machine address
    255.255.255.0 as subnet mask
    192.168.1.254 as default gateway

    (all the above assuming you didn't change the default IP of the Netopia router)

    159.134.237.6 as primary DNS
    159.134.237.6 as secondary DNS

    Eircom Secondary DNS : 159.134.248.17
    To manually enter in DNS information, edit /etc/resolv.conf
    an ip per line is the format.
