   I have just set up a Linux machine running Ubuntu 10.10/Gnome (that's the    
   way it came, I haven't even attempted to modify anything.) It plugs into    
   port #2 of a Netopia router, while the eCS machine uses port #1. It seems    
   that almost as soon as I do something via the internet on the Linux    
   machine, it disables completely internet access from the eCS one: http,    
   ssh, telnet, ftp all time out with no explanation, while things look OK on    
   the Linux side.   
      
   To get eCS back on line, I must not only unplug the cable from the Linux    
   box, but reboot the router as well.   
      
   I have an old Mac laptop that I used to use together with the same eCS    
   machine and the same router without any problem, so it's not just having    
   two computers going through the router that causes the trouble. Also, when    
   the eCS side becomes disabled, it appears to be disabled at the computer    
   itself, because I cannot even reach the router via its web interface: such    
   an attempt times out, even though there's no traffic beyond the router.   
      
   I have swapped the cables at the router ports (there are 4 ports, and I    
   tried several combinations of all of them) and rebooted everything but    
   that does not help.   
      
   One peculiar thing is that both computers claim to be at 192.168.1.105    
   (from ifconfig lan0/eth0) which would point to a competition, but why    
   would they both get the same address? Why 105 rather than 100 or 101? Why    
   does Linux always seem to win regardless of whether it is plugged in port    
   #1 or #2, or whether it is not even plugged in until well after eCS has    
   already grabbed 192.168.1.105 and been shown to connect without problem?   
      
   If this is the cause of the problem (rather than a symptom) I should be    
   able to force an address via ifconfig, but should I do it on both    
   machines, and how much should I specify? The syntax of ifconfig has so    
   many parameters!   
      
   Thanks,
