[root@172 mickey]# k9copy
k9copy: error while loading shared libraries: /usr/lib/libk9copy.so.0: cannot restore segment prot after reloc: Permission denied


What is problem.

Jim

Have you tried running it as root ? I'm not suggesting you should do so all the time, but if it works you know that the problem is just permissions, you can find the exact program that's causing the problems, change the permissions for that program, and things should work. Does that user have permission to write to the dvd-burner and the temp dir for K9 ? Good first places to look.

Best of luck....

Yes i have run at SU and get same error message.
The /usr/lib/libk9copy.so.0 and libk9copy.so.0.0.0, both have rx priv.
Only SU has write priv.

Jim

Downloaded Rpm off Redhat site and got same error message.
Download k9copy.tar.gz and compiled and still get same error message
Made a bug report on Sourceforge.net k9copy site.
Just have to wait and see.

Jim

Have you used the beta version from this site?

It seems to be working for me.

Running tail -f /var/log/messages
When I execute "k9copy" w/o quotes , I get the log in /var/log/messages. Same happens when running
as SU or user.
From What I can see , I'm having problems with Selinux. How do I fix it? Relabel etc etc

I would think these two programs (usr/lib/libk9copy.so.0 and libk9copy.so.0.0.0) need more than rx permissions. I think they both need w too. Have you tried it ? SELinux has fine tuned granular control of permissions, as I understand it. Seems like it is preventing you from using K9. I'm sorry but I don't know a thing about SElinux. Does SElinux have a forum ? I would think they would, and I bet they have already run into and solved this problem.

Best of luck...

David

P.S. Have you made sure you can write to whatever dir K9 is using ? Both temp dir and final ? Those error messeges mention /dev/hda1, is your /home on same partiton as / ? You might want to make sure K9 is writing to someplace under your /home.

Good luck....

THIS FIXED THE PROBLEM.

Thank you , the chcon command did the job.
