But running any UML on a hardened base system (libc) fails badly. And now I tested it with the Gentoo Live DVD. I had to rebuild the linux executable using the gcc of the Live DVD. Then I was able to start the UML guest (using the linux program compiled under my hardened system produced just the same stub entries error messages as posted before) And the UML guest itself assigned an static IP to its eth0 interface (I was however to stupid/unexperienced to get a ssh login working at the Live system). So you're right - it is the hardened glibc which prevents at a hardened Gentoo UML. -- Toralf pgp key: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 0076 E94E ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
