mingetty on SuSE

mingetty on SuSE

[Carsten Grohmann]

Hi!

I use mingetty on my SuSE 7.1. Mingetty needs read access to many
different types in the proc directory to run correct. 
Now me question: Is it possible to limit the access to the different
types only to the proc directory? I think no, but I hope anyone has an
solution. In the other case I can not get mingetty the permissions,
because it can read to much files. What getty programs do you use?

Thanks 

  Carsten

mingetty also runs on our machines, but I don't see this behavior.
I assume that you mean that mingetty is probing the /proc/PID entries, and
thus you are seeing audit messages for the various domains.  Unless
mingetty truly needs access to other domains' /proc/PID files, I'd suggest
using dontaudit (or auditdeny, if you haven't applied the dontaudit
patch) rules to suppress the audit messages but continue denying access.
See the xdm.te file or the user_macros.te file for examples.

I mean this is a SuSE specific problem. Today I rebuild the source rpm
"mingetty-1.00-1.src.rpm" from rpmfind.net and replay the suse file with
this package. It works fine. I do not get follow log entries:
"May 10 07:51:07 myserver mingetty[231]: cannot open(/proc/2/maps):
Permission denied"
I recommend all SuSE users to replace the mingetty programm.
