I am more of a UNIX ignoramus than I should be. What do I have to do to give
myself permission to write into /etc ?
Here is what /etc looks like:
Filename Type Permission Audit Ext Fmat Owner Group Links
-------------------------------------------------------------------
etc Dir rwxrwxr-x fff--- ---- OMVSKERN OMVSGRP 16
I can log on as IBMUSER and it accepts chmod u+rw /etc with no error but
nothing changes.
What am I supposed to do? z/OS V3R1
The simplest way:
define CL(FACILITY) BPX.SUPERUSER profile and permit AUTH(READ) to your
user.
Then you will be able to "su" command.
"su" means you want to be superuser vel batman vel superman vel Chuck
Norris. You will be allowed to all possible filesystem actions despite
of "rwx" settings.
However without the above a person with effective rwx (even less) is
able to create file inside directory. Otherwise you should see ICH408I
in the syslog. Did you observed any?
BTW: "write to /etc" mean write to a *directory* - it is not the same as
write to file. w (write) to directory allows you to create or delete
files inside. Even those files which you have no authority to even read.
With different owner.
Advice: do not perform any test on /etc. Use some other directory
instead. It can be /u/your_home/test_dir1
