UNIX for Advanced & Expert Users

That would have probably worked if the lib had been moved to a different directory while keeping its original name but I understand the issue is it has been renamed.

This is why you don't run things as root unless they actually need root. If they go on a rampage they'll run into walls instead of through walls.

Just reading/writing the file won't be enough. You'll need a means to set it executable, too.

Try export LD_PRELOAD=/path/to/lib.so, that might satisfy the linking dependencies...maybe...

I am an admin, whenever I work , I have to be root, I am hired to login as root
Of course if i dont need to be root, I never am ...
to do my expreince I had to be root of course
fyi, i tryed ld_preload, wont do it, it is AIX it doesnt even support ldconfig ...

and most importantly, this a test server ... there is no way I would have attempted this elsewhere ...


BUT! thank you

It seems on AIX that would be LDR_PRELOAD=xxx but I doubt this can work anyway as the loader itself depends on libc to fulfill its tasks ... a catch-22 situation.

I was under the impression that LDR_PRELOAD was the preload directive, like the normal UNIX LD_PRELOAD. I think he would need LIBPATH which is the equivalent of LD_LIBRARY_PATH, would he not ? I guess it may be worth trying both...

LD_LIBRARY_PATH allows to set a list of directories where to the program loader will look for libraries. This is fine when the library you want to run is not in the default path but has kept its initial name. The OP issue is not the library being elsewhere but a library name mismatch due to a renaming. A preload was a good guess as it accepts a full arbitrary library name.

Back to post #1 .
Can you post the full hierarchial name of the the original file and the full hierarchial name of the file now?


Without trying the commands on on the critical library, do any of the following unix commands still work on expendable test files?

Code:

ls
tr
cat
ln
chmod
