Hi all, Has anyone here ever used security enhanced linux? I got the following bug report from an SELinux user which includes an error message from one of SELinux security systems. Never having used SELinux myself, I don't quite understand the problem Dr. Pan is observing once he uses chcon to change the security state of the ifeffit library. And I don't have a machine on which to explore this problem. I am hoping someone here might be more knowledgable than I. If anyone can offer any assistance to Dr. Pan, that would be great. Thanks, B ---------- Forwarded Message ---------- Subject: Horae-70 installation problem Date: Saturday, January 15, 2011, 01:34:29 am From: Guoqiang PAN To: Bruce Ravel Dear Dr. Ravel Hi, thank you very much for the horae-70 for artemis, athema and hephaestus XAFS software. Due to the detail for the installation, I have installed in my PC linux of Fedora Core 10. When artemis has been installed, it was failed to run correctly. There is a detailed explanation of it in the attachment. I fixed it using chcon -t textrel_shlib_t '/usr/local/lib/perl5/site_perl/5.10.1/i686-linux/auto/Ifeffit/Ifeffit.so' Afterwards, it seems work, but the data in the interface panel could not be changed,please refer to the attached snapshot pictures. My system information as follows: [gqpan@localhost horae-070]$ uname -a Linux localhost.localdomain 2.6.27.5-117.fc10.i686 #1 SMP Tue Nov 18 12:19:59 EST 2008 i686 i686 i386 GNU/Linux Thank you for your help!
