Re: [PLUG] Newbie level DHCP client question
|
255.255.255.255 is broadcast. You should also see a netmask something
like 255.255.255.0.
Not being able to ping points to a routing problem. Make sure that your
routing tables are correct: type 'route' at the command line and you
should get something like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.1.0 * 255.255.255.0 U 0 0 0
eth1
default 192.168.1.1 0.0.0.0 UG 0 0 0
eth1
The default line tells you that all traffic is directed by default to
eth1 (eth0 in your case), through a gateway (your modem).
