Did you not see my answer from last Friday?

You are not using the command correctly.
---
Your problem is that the commands you use to change the value starts a new shell, \
changes the value in the new shell, then that shell exits. The "ulimit" command only \
affects the current and child shells, not the parents.

If you want to change the value permanent you can add the following line to \
                /etc/profile or ~/.profile:
---
ulimit -c 1024
---

Example:
---
root@ROOter-Uppsala:~# ulimit -c
0

root@ROOter-Uppsala:~# busybox sh -c 'ulimit -c 1024'

!! This starts a new shell, changes the ulimit value in that shell, then it exits and \
you are back with your first shell

root@ROOter-Uppsala:~# ulimit -c
0

!! no change

root@ROOter-Uppsala:~# ulimit -c 1024

!! "ulimit" is a shell built in command, so this changes the value in
!! the current shell

root@ROOter-Uppsala:~# ulimit -c
1024
