Re: Linux LPAR network configuration

[Pete Helgren <Pete@xxxxxxxxxx>]

Yes.  That manual, The "Linux on iSeries Implementation Guide", this 
helpful guide on Developerworks: 
http://www-128.ibm.com/developerworks/linux/library/l-pow-sles9/#resources, 
and the Suse site.  What is missing in all this a simple, well 
described, example scenario that says something like:

Your i5 Ethernet address is: XXX.XXX.XXX.XXX
Your i5 Ethernet subnet mask is: XXX.XXX.XXX.XXX
Your i5 Ethernet gateway is: XXX.XXX.XXX.XXX

Your virtual Ethernet address is: XXX.XXX.XXX.XXX
Your virtual Ethernet subnet is: XXX.XXX.XXX.XXX
Your virtual Ethernet gateway is: XXX.XXX.XXX.XXX

Your Linux Ethernet Address is: XXX.XXX.XXX.XXX
Your Linux Ethernet Subnet is: XXX.XXX.XXX.XXX
Your Linux Ethernet Gateway is: XXX.XXX.XXX.XXX

Here is how to configure this.......

Instead we see all the pieces and never the whole Tamale.

I *think* my problem is that I set the virtual Ethernet and the Linux 
Ethernet addresses the same, which didn't make any sense at the time and 
still doesn't (but I had nothing else to go on...).  So I need to figure 
out how to change the Linux addresses from the command line. 

Thanks for pointing me back to my starting place I had wandered off 
chasing rabbits for a while.  I'll let you know how it goes (once I get 
the addresses changed).
