/*
 * By default: nskrb will be running with new heimdal library.
 *
 * If you need to revert to old heimdal library, please follow the
 * below steps.
 */

<Step 0>
---------
(a) Goto shell -> shell
(b) Old nskrb binary is present under directory - /var/netscaler/nskrb_old_binary

pwd:
/var/netscaler/nskrb_old_binary
root@node0# ls -lrt
total 2416
-r-xr-x---  1 root  wheel  2451440 May 10 05:10 nskrb_1_5_3

<Step 1>
---------
Get the process id running for nskrb by executing below command.

pwd:
/netscaler
root@ns# ps -aux | grep nskrb
root       705   0.0  0.1   9232   2672  -  Is   21:47    0:00.00 /netscaler/nskrb nsauth

<Step 2>
---------
Copy the newer nskrb library to temporary location

pwd:
/netscaler
root@ns# cp nskrb /var/tmp/

<Step 3>
---------
Kill the process id asociated with new nskrb

pwd:
/netscaler
root@ns# kill -9 705

<Step 4>
---------
Move older nskrb_1_5_3 to nskrb

pwd:
/netscaler
root@ns# cp /var/netscaler/nskrb_old_binary/nskrb_1_5_3 nskrb

<Step 5>
---------
Wait for nskrb process to come up

pwd:
/netscaler
root@ns# ps -aux | grep nskrb
root      6960   0.0  0.1   8752   4476  -  Is   22:16    0:00.00 /netscaler/nskrb nsauth
