    Can't ping outside LAN can't FTP local or externally


    For some reason I can ping machines on my local network but I can't connect to an ftp (local or external) nor can I ping machines outside my local area network. Something that looks a bit suspicious to me is that my MAC address is FF:FF:FF:FF:FF:FF when quering via ifconfig.
    Code:
    eth1      Link encap:Ethernet  HWaddr FF:FF:FF:FF:FF:FF
              inet addr:192.168.0.3  Bcast:192.168.0.255  Mask:255.255.255.0
              UP BROADCAST NOTRAILERS RUNNING  MTU:1500  Metric:1
              RX packets:472 errors:0 dropped:0 overruns:0 frame:0
              TX packets:34 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000
              Interrupt:45 Base address:0x00000300
    
    lo        Link encap:Local Loopback
              inet addr:127.0.0.1  Mask:255.0.0.0
              UP LOOPBACK RUNNING  MTU:16436  Metric:1
              RX packets:0 errors:0 dropped:0 overruns:0 frame:0
              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:0
    Also I think the following information contained in /etc/dhcpc/hcpcd-eth1.info may be relevant if anyone can decipher it:

    Code:
    IPADDR=192.168.0.3
    NETMASK=255.255.255.0
    NETWORK=192.168.0.0
    BROADCAST=192.168.0.255
    GATEWAY=192.168.0.1
    DNS=192.168.0.1
    DHCPSID=192.168.0.1
    DHCPGIADDR=0.0.0.0
    DHCPSIADDR=0.0.0.0
    DHCPCHADDR=FF:FF:FF:FF:FF:FF
    DHCPSHADDR=00:0F:B5:1C:E1:98
    DHCPSNAME=
    LEASETIME=86400
    RENEWALTIME=43200
    REBINDTIME=73440

    About FTP, do you have a firewall blocking the FTP-port, either in the router or in your own machine? And about pingng, I am not sure but it may be that the router does'nt know where to forward the echo's coming back...

    Can any machine on your LAN ping out past the gateway?

    FF:FF:FF:FF:FF:FF is the broadcast address for the MAC. I don't know Mandriva but it seems strange that it is reported as the hardware address in ifconfig.

    reporting it is normal the fact that it was all FF's is strange though it coulld be the addy but that should have nothing to do with the current problem the only time you need mac addy's in when that nic is connected to broadband cable
