How to restore default password on Alcatel-Lucent OmniPCX


As your request my friends, I want to share about restoring the ‘root’ and ‘mtcl’ password to default on Alcatel-Lucent OmniPCX if you have lost it.

A. For Alcatel-Lucent OmniPCX Enterprise (Media Gateway type):

1. From terminal console, Reboot OmniPCX into single user mode using Grub. at the boot prompt, hold on boot process and then press ‘e’ (without quote) to edit the kernel line from default boot configuration.

2. Select cursor to the kernel, by default system will load the kernel from /boot/vmlinux directory and root directory location was on /dev/hda5. and then press ‘e’ once again to edit the parameters.

3. at the end of the line, add ‘S’ and then enter

4. Boot using modify parameter above by press ‘b’

5. In this step you will boot into single user mode and you can change the password of root and mtcl. at the prompt enter this command:
# passwd (this will change the 'root' password)
# passwd mtcl (this will change the 'mtcl' password)

after you set up the root and mtcl password, reboot your system with command:
# shutdown -r 0

B. For Alcatel-Lucent OmniPCX 4400 (Crystal Type):

1. Same step with OXE, interrupt boot loader by hold any key on this section:

*** BIOS Version 3BA_24095_AAAB_07 ***
*** Generated on fillld0f00258 on Nov/09/2006 at 15:15 ***
*** CPU6 Step 2 version 3BA 23197 : 0.1 ***
*** ELAN SC520 @ 100MHz ***
...........
> System Times
CLK Time : Wed Jan 30 02:51:09 2008
Analyzing the input file
----- Auto Boot in 1 s -----

2. Edit boot loader configuration, please press ‘c’ to edit boot parameter with command line in this section:

GRUB version 0.5.96 (640K lower / 130048K upper memory)
Press enter to boot the default OS [0], 'c' for a command-line,
or give an another entry number
[0]: Boot GNU/Linux [default]
[1]: Install GRUB into the hard disk

3. Enter this command on your terminal prompt:

grub>root (hd0,4)
grub>kernel /boot/vmlinuz root=/dev/hda5 console=ttyS0,9600 panic=5 single
grub>boot

4. System will booting to single user mode, change the root and mtcl password using this command:

# passwd (this will change the 'root' password)
# passwd mtcl (this will change the 'mtcl' password)

after you set up the root and mtcl password, reboot your system with command:
# shutdown -r 0


done!

remark: you must change the root and mtcl default password to securing your system

      hi expert,
      so, you didn’t have any experience about this right? how come you called yourself as an expert? (i’m sorry just kidding….. :D) refer to your question:
      1. Can you explain to me by email about what you have done while resetting your password and what a release used with a screenshot?
      2. Hmm…Radius server on OXE? it’s interesting, but….what for? can you tell me the main concept?

        hi thank you .
        I am expert and I am not GOD (about your sentence🙂 i’m sorry just kidding).
        I will send screenshot ASAP and also will describe my issue about RADIUS server in email.
        for comfort and for god sake forget about “expert ” , I am technical person.

    What about Office not enterprise?
    Is it possible to restore the root password?

    Seems that it a solution for old systems. you are not getting the prompt through which you can enter the command “passwd” . You are getting a message:

    “Give root password for maintenance ”
    or type Control-D for normal startup:”

    Now if you know the root password in order to get into the …# prompt. You can do it in the normal way anyway. I mean let the system boot, and get into it by the root user, and change the “mtcl” user’s password.

    Bottom line if you change the Root password, and don’t know what it is – You are in deep deep trouble.

    That was very helpful, thanks very much, but my only problem now is that when the system reboots is reboot in grub mode every time.
    It doesn’t go on to boot in Linux mode. Please help me.
