I don't know if I understand your question, which hwaddr do you want where?
If I type ifconfig as root, I get the hardware adress (among others).

so please allow me to tell you the truth and detail that maybe you can help me.
i connect to the internet via a ADSL modem (ATU-M system) included with DHCP server and Router ( i connect my computer to ADSL modem via a ethernat )
now i want to change my mac address and connect to the internet with above hardware.
but when i type
ifconfig eth0 hw ether 00:12:13:14:15:10
and change my mac address successfully i can't connect to my router.. now i want to know how can i change mac address and connect to my router successfully?

I once had a modem that requered my first used hwadress, and then I chanced it the way you did. For a modem with router and dhcp-server I would expect you to be able to use any hwadress.
Is your dhcp-client running? "ps -e|grep dhc"
is your eth0 up?

Thanks folkert....
my new problem is:
i changed my mac address and want to connect to my router->
ifdown eth0
ifconfig eth0 hw ether 00:133:63:13:92
dhclient eth0
i connect to my router successfully but my browser can't open anything ( Firefox) but in terminal i can connect to each site but my browser is my problem , how can i fix it?
i followed this way:
ifconfig -a
eth0
Link encap:Ethernet HWaddr 00:133:63:13:92
inet6 addr: fe80::213:d3ff:fe63:1392/64 Scope:Link

now how can i fix my broswer that work with this new mac & ip address?
in windows i did it successfully( with firefox ) but in linux i can't do it with my browser(firefox)

I don't think your browser care's about your mac and ip address. I wouldn't know why your browser won't work. can you use another browser, maybe you have the textbrowser lynx. try "lynx google.com" Did you use ping and nc as root or as your regular user?

Thanks , i think so , but thanks anyway , in this forum you were that help me and follow my question , Thanks a lot for all things
