in my Linux server I have the following:

Linux Version - RedHat-Linux- 5.3.0.0

(this Linux server only only one LAN)

   more /etc/sysconfig/network-scripts/ifcfg-bond0:0

   DEVICE=bond0:0
   ONBOOT=yes
   BOOTPROTO=static
   IPADDR=10.10.10.12
   NETMASK=255.255.255.0

my problems:

1. why I get HWaddr 00:00:00:00:00:00 and not the real MAC address
2. I cant ping to other server with 10.10.10.11 from my server
3. is it possible to define bond0:0 when I have only one LAN (eth0)

other info:
