I do have an ip address configured in ifconfig for eth0.
Also, I didn't have the hosts files set up but unfortunately it didn't
help.. :(
Two linux boxes.. the first can ping the second just fine..
The second pings the first but doesn't receive a response.
The first box's packet count still goes up for both TX and RX on
eth0.
I disabled linux from setting up the interfaces and routing table on
startup so I could do it step-by-step. Here's what I have:
________________
### No interfaces or routes configured yet...
$ route add -host 127.0.0.0 lo
$ route
Kernel IP routing table
Destination Gateway Genmask
Flags Metric Ref Use Iface
localnet * 255.255.255.255
UH 0 0 0 lo
$ ping -c 4 127.0.0.1
PING 127.0.0.1 (127.0.0.1): 56 data bytes
--- 127.0.0.1 ping statistics ---
4 packets transmitted, 0 packets received, 100%
packet loss
$ ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:3924 Metric:1
RX packets:4 errors:0 dropped:0
overruns:0 frame:0
TX packets:4 errors:0 dropped:0
overruns:0 carrier:0
collisions:0 txqueuelen:0
### The RX and TX are at 4.. but I got 100%
packet loss.
$ ifconfig eth0 192.168.1.53 netmask
255.255.255.0 broadcast 192.168.1.255 up
### This automatically put an entry into the
routing table (192.168.1.0)
$ route add -net 127.0.0.0 netmask 255.0.0.0 lo
### This command fails if I don't put in the
netmask 255.0.0.0.. ?!??!
