Netscaler MPX / VPX

Now from time to time you might come by this, you have a customer which has a Netscaler setup and they have forgotten the password for the device. What do you do ?
If you have a MPX you need to connect to the device using a serial cable and use for instance Putty to connect to the serial port. If you have an VPX you just need to open the console. Now when the device boots you need to press CTRL + C now on the VPX it is simple the boot menu appears


Then you just press 4 and go into single user mode. On the MPX we have to press CTRL + C simultaneously as well when the following appears in the console
Press [Ctrl-C] for command prompt, or any other key to boot immediately.
Booting [kernel] in 2 seconds…
Now to start the MPX in single-user mode you have to type either boot –s or reboot — -s torestart in single user mode. When you are in single user mode the console will look like this.


Next we have to mount the flash device since this is where the config file resides. Now on different devices this flash device has different names
For VPX this device is called /dev/ad0s1a
So first we have to check disk consistency first before we can mount the device.
fsck /dev/da0s1a (This checks disk consistency)
mount/dev/da0s1a/flash (This mounts the drive under the folder /flash )
df –l (List the devices and where they are mounted)


Next we need to change directory to the flash drive where the config file is located.
cd /flash/nsconfig from there


Next we use a grep command to create a new config file but without the line which contains the passoword string.
grep –v “set system user nsroot” ns.conf > new.conf
Next we need to rename the current config to another name
mv ns.conf old.ns.conf
mv new.conf ns.conf

After this is done we have a new config file without the password for nsroot and we can reboot.

At the boot screen, you will see “SYSLINUX 4.02 … Boot:”, write to the next “menu.c32”
Secondly, you can see a blue window. Move to “xe-serial” and press “tab”
Now, you can read command line start with “mboot.c32…..”. You have to change this part of the line “xencons=hvc console=hvc0” and write “console= ttySO,115200n8 single”.
And press “Enter”, the server continue the starting process.
Then you can see the command line interface, write “passwd” to change your root password

1. Press Clear hole for 10s
Once you release the “Clear” button, only the password protection will be removed. All other configuration settings will remain intact, and the switch will not reboot
If you would like to disable the clear password button on the front of the HP Procurve switch then enter the following
>conf t
Switch(config)# no front-panel-security password-clear
You will also notice the reset button next to the clear button. To disable this button enter the following.
Switch(config)# no front-panel-security factory-reset
Both buttons are now disabled.If you would like to enable these buttons again, do so with the commands below.
Switch(config)# front-panel-security password-clear
Switch(config)# front-panel-security factory-reset

Finally if you are unsure of the status of the reset and clear buttons on the procurve switch then enter the following.
Switch(config)# show front-panel-securityJuniper:

1. Connect your Console cable with settings 9600/8/N/1
2. Power on the device and watch the screen for the line:
Hit [Enter] to boot immediately, or space bar for command prompt.
When you see that line, hit the SPACE BAR and you will receive an OK prompt.
3. At the OK prompt, you want to the system into single user mode by issuing the command
boot -s

4. The system will boot in single user mode and you will then be prompted if you want to enter the path name for shell or “recovery” for root password recovery. Since we are trying to recover the password, we will enter
5. The system will then boot and run a recovery script and place you in at the > prompt
> edit
# set system root-authentication plain-text-password
# commit
# exit
> exit
Reboot the system? [y/n] yRuckus:
