Thanks for replay.

Yes but same problem!

ifconfig eth1

Did you removed or add any network device recently?
MAC address needs to be entered in the **_persistent-net.rules file for your interface which is in the /etc/udev/rules.d/ directory or similar,depends on the distro.
(** are random numbers.)

Quote:

cd /etc/udev/rules.d/
-bash: cd: /etc/udev/rules.d/: No such file or directory

How i should add it?

Search for udev,it should be in /etc then find the rules.You're using Debian right?

Go here.You'll see that they say that there should be /etc/udev/rules.d/ in Debian.Try

Code:

whereis udev

Code:

find / -name'70_persistent-net.rules' 2>errors.txt

or try

Code:

find /rules.d 2>errors.txt

Code:

find /udev 2>errors.txt

Post errors from errors.txt files if any.
Anyway if you follow instructions on the link above you should be able to set things (if you find udev directory),if not,post back.

# whereis udev
udev:

errors.txt:
find: /udev: No such file or directory

Its not /udev.
Use this command

find / -name udev

You will find it in /etc.

Also just paste output of "ifconfig"

output ifconfig:

I Install the udev package
# apt-get install udev

now i have /etc/udev/rules.d/

What's next step?

As I said there shouldn't be

Quote:

HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 -00

There should be your MAC address.You didn't post the output from all commands that I've suggested.Did you try to follow the guide that I suggested?You can create a new file,for example

Code:

/etc/udev/rules.d/010_netinterfaces.rules

then add to it;

Code:

KERNEL="oldnameprefix*", SYSFS{address}=="MACaddress",NAME="newname"

with correct values.It's all in the guide.
EDIT:Look at my post no.4.
