resnet fix

1. As superuser, edit the /etc/rc.d/rc.local file. You can use a text editor like Emacs in a terminal to do this.
   NOTE: On some Linux systems, the file might be located at: /etc/rc.local. Ubuntu 6.1 is known to have the rc.local file located there.
   

2. Add the following line to the end of the file:
   
   echo 1 > /proc/sys/net/ipv4/neigh/eth0/locktime
   

3. Save the file, and restart your computer. The fix will now be applied on every system startup.
