Sorry, I’ve never used MAC cloning before, so I don’t know what might be going wrong.

My Internet provider controls legitimate access through checking of hardware MAC address of network card. I would like to use alternatively also second computer – portable notebook – with another hardware MAC address. Internet provider assigns constant (nat?!) IP address, not a DHCP one. Linux/Fedora has simple straightforward provision for such MAC address cloning. I have prepared for OpenSolaris two scripts supposedly doing this trick. Listing of both is included below. However I cannot got the network connection. Any help/suggestions?

The scripts follow:

#!/bin/bash
#wired-up script
sudo svcadm disable network/physical:nwam
cd /etc
sudo cp -p OK_hostname.rtls0 hostname.rtls0
sudo cp -p OK_defaultrouter defaultrouter
sudo cp -p OK_resolv.conf resolv.conf
cd inet
sudo cp -p OK_netmasks netmasks
sudo ifconfig rtls0 ether 00:19:D1:FE:C4:B4
sudo ifconfig rtls0 netmask 255.255.255.0
sudo svcadm enable network/physical:default

#!/bin/bash
# wired-down script
sudo svcadm disable network/physical:default
sudo svcadm enable network/physical:nwam

Thx for any help

What were you trying to configure, and what went wrong?

tried to use nwam on solaris11 express this evening.
This did not work so tried to disable service and then do ipadm manually, this fails as well.
Had to reinstall without choosing nwam on text installer and then ipadm static config worked ok

This reply reminds me, I should write a blog entry about trolls. My twitter feed gets updated more often than this blog. http://twitter.com/unixygoodness

Wow, a post today Sept 12 and previous post June 23.
It’s like, wow, there is still a pulse over there in Oracle Solaris Studio
land but it’s very weak. Maybe you have customers who only ever
check in with you once a year? Maybe I’m behind a Great Firewall where
none of the good stuff gets through? Really, I’m not trying to be
sarcastic, what’s the deal here? Why does this blog exist?
My working theory is that this post was a secret message intended for spy Anna Chapman that needs to be obscured from onlookers but not lost in too
high a noise::signal ratio. Am I close?

You are correct, I’ve changed it to say he is a contributor to the language.

Comment on Virtualization terms by Chris Quenelle

Thanks for pointing this out, Jeff! I think the Type 1 and Type 2 terminology is widely used, and it’s important to know if you want to understand what people are talking about. I updated the blog post to include those terms.

Concise and useful. Thanks. Another term that sometimes crops up is the “type 1″ versus “type 2″ hypervisor. As I make it out, “type 1″ is your “hypervisor that runs on the hardware”, and “type 2″ is your “hypervisor that runs as an application”. Correct me if wrong.
