Hi,
I am running on FC4 and I installed Cisco VPN client software,
however when I run vpnclient I am getting the error message :
"vpnclient: error while loading shared libraries: /opt/cisco-vpnclient/lib/libvpnapi.so: cannot restore segment prot after reloc: Permission denied"
This is strange.
Have you tried
chcon -t textrel_shlib_t /opt/cisco-vpnclient/lib/libvpnapi.so
Friendly neighbourhood Paul Howarth correctly guessed it to be related
to SELinux.
I am able to run the vpnclient by disabling the SELinux using
setenforce 0
The chcon command did not work (apparently it is not supposed to work
in FC4)
I get a error message "type=AVC msg=audit(1147460693.437:11955217):
avc: denied { execmod } "
if I disable selinux and run the vpnclient command.

This should fix

setsebool with execmod is not working either.
I have attached the relevant files as well. Any ideas ?
This should give you an idea of the SELinux version
