File permissions
by Robert Spangler 11 Mar '12

11 Mar '12

Hello, I need to know if there is something I am missing about file permission as I believe I am seeing some strange stuff on my system. I have a directory as follows: drwxrwxrwx 7 root root 4096 Mar 10 13:35 temp In this directory I have a file: -rw-r--r-- 1 root root 137 Oct 30 02:16 208-109-248-33test As a normal user should I be able to rename this file? I believe that only root should be able to modify this file but as a normal user I am able to rename it without elevated privileges as so: temp $ mv 208-109-248-33test 208-109-248-33-mv [Sat Mar 10 13:41:05] /temp temp $ lt 208* -rw-r--r-- 1 root root 137 Oct 30 02:16 208-109-248-33-mv How is this possible? If it is possible what am I missing or not understanding? Thnx. -- Regards Robert Linux The adventure of a lifetime. Linux User #296285 Get Counted http://linuxcounter.net/

Hi All, Am getting this: ---> Package xulrunner.i686 0:1.9.2.26-2.el6.centos will be updated --> Processing Dependency: libmozjs.so for package: gxine-0.5.905-1.el6.rf.i686 --> Finished Dependency Resolution Error: Package: gxine-0.5.905-1.el6.rf.i686 (@rpmforge) Requires: libmozjs.so Removing: xulrunner-1.9.2.26-2.el6.centos.i686 (@updates) libmozjs.so Updated By: xulrunner-10.0.1-2.el6.centos.i686 (updates) Not found Available: xulrunner-1.9.2.24-2.el6.centos.1.i686 (base) libmozjs.so Available: xulrunner-1.9.2.26-1.el6.centos.i686 (updates) libmozjs.so You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest Running the --skip-broken gets me updated but the problem is still there. Would anyone have an idea as to how to fix this, please? Thank you, Phil

The CentOS "contrib" repository
by Yves Bellefeuille 10 Mar '12

10 Mar '12

According to the Wiki, the CentOS contrib repository "contains packages contributed by CentOS users which do not overlap with any of the core distribution packages". The repository seems to be empty. Are contributions actually welcome? Are there any policies about proposing packages?

Errors trying to install centos 6.2 as an lxc guest under centos 6.2 host
by C. L. Martinez 09 Mar '12

09 Mar '12

Hi all, I am trying to install a centos 6.2 container under centos 6.2 host using libvirt and virt.-manager. I have selected "OS Container" option, but when I try to launch this guest virt-manager returns me this error: PATH=/sbin:/usr/sbin:/bin:/usr/bin LIBVIRT_DEBUG=3 LIBVIRT_LOG_OUTPUTS=3:stderr /usr/libexec/libvirt_lxc --name mysqlsrv --console 20 --handshake 23 --background --veth veth1 PATH=/bin:/sbin TERM=linux LIBVIRT_LXC_UUID=41bfb51b-294e-1ba9-16c9-fc2e3a345ff6 LIBVIRT_LXC_NAME=mysqlsrv /sbin/init 16:39:23.115: 1: info : libvirt version: 0.9.4, package: 23.el6_2.6 16:39:23.115: 1: error : lxcContainerChild:896 : cannot find init path '/sbin/init' relative to container root: No such file or directory I have followed these instructions: http://libvirt.org/drvlxc.html and http://berrange.com/posts/2011/09/27/getting-started-with-lxc-using-libvirt/ I have tried to do the same using rhel6.2 instead of centos 6.2 and results are the same ... What am I doing wrong?? Do I need to copy all host files to this guest?? I f yes, then, how can I apply security updates to these guests?? Thanks.
