Forget your NetScaler application password, nothing to worry about. here you know How to recover/reset the password for a NetScaler appliance
Today I am going to share with you that how you can easily go to rest or recover your password of NS application. This should not happen that you forget your NS Appliance password, but never to worry here are a couple of steps in which you can achieve this, please do not forget to comments if this helps you some or other way. Cheers/Shiv
First thing first you should avoid HA failover due to reboot, so it is recommended to set STAY PRIMARY on the primary node and STAY SECONDARY on the secondary node.
All work here done on a primary node if you do not have secondary then no need to worry this point.
In order to reset the NSROOT password, you must boot the appliance into single user mode.
Connect the console cable to the Netscaler Serial Console (9600 baud, 8 bits, 1 stop bit, No parity) of the NetScaler appliance. In case of NetScaler VPX access NetScaler through vSphere console.
1. After connecting to the Netscaler Serial Console, restart the NetScaler appliance.
2. Press Ctrl+C keys simultaneously to Boot in kernel.
3. To start the appliance kernel on a single user mode, run boot -s. If boot -s does not work, then try reboot — -s.
4. Press ENTER key to display the # prompt, and run the following command to verify the /flash drive consistency:
$ /sbin/fsck /dev/ad0s1a
$ /sbin/fsck /dev/ad0s1a
5. Run the following command to display the mounted partitions:
$ df
$ df
6. Check if /flash drive is created, then run the following command to mount the flash drive:
$ /sbin/mount /dev/ad0s1a /flash
$ /sbin/mount /dev/ad0s1a /flash
If the preceding command fails to mount the flash drive, then run the following command to create the flash directory and then run the preceding command again to mount the drive:
$ mkdir /flash
$ mkdir /flash
In case of NetScaler VPX on VMware, the disk uses SCSI emulation and the device name of the flash drive is da0s1a.
7. Run the following command to change to the nsconfig directory:
$ cd /flash/nsconfig
$ cd /flash/nsconfig
8. Create a new configuration file that does not have commands defaulting to the nsroot user:
$ grep –v “set system user nsroot” ns.conf > new.conf
$ grep –v “set system user nsroot” ns.conf > new.conf
9. Make a backup of the existing configuration file:
$ mv ns.conf old.ns.conf
$ mv ns.conf old.ns.conf
10. Rename the “new.conf” file to “ns.conf”:
$ mv new.conf ns.conf
$ mv new.conf ns.conf
11. Run the following command to restart the appliance:
$ reboot
$ reboot
12. Log on to the appliance using the default nsroot user credentials (nsroot/nsroot).
13. Reset the nsroot user password of your choice:
$ set system user nsroot <New_Password>
$ set system user nsroot <New_Password>
Have a happy learning and sharing friends.
