You're totally right. We should reconsider what we echoed by audit2allow even if we could work our own modules on our machines. Surely, interfaces would provide more privileges than what is really needed... I rethought that httpd_t can execute bin_t would not be a good solution... I can co-operate any time on you guys work and want to make a small bounce on computer security. I recognized that what I want and you guys want is the same... Thanks ! We're waiting you guys come to our country and talk on your beliefs. ################################################## member, Secure-OS Users Group, JP Officer, System-Information, Signal School, JGSDF ################################################## > > Maybe I should rewrite my own program ...segatex...by this > > summer,though. > > Or are there other project doing the same thing? > > Karl's project? > > > > http://sourceforge.net/projects/segatex/ > > > > http://intrajp.no-ip.com my homepage > > > > > > Officer,System-Information,Signal School, JGSDF > > > > > > -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-selinux-list
