I have been using my +local bin directory for years and I have never had execute refused so +this must reflect some deep system level screwup relating to lcl and +maybe something in pam.d. That is unknown country for me. +Until yesterday there was no lcl group, only user lcl. The group for +lcl was live, which I have +removed from my group list. live was my primary group, now it is lcl +which I added yesterday. Ownership of my files is now lcl:lcl and in +/home/lcl/bin the permissions are nearly all 755. +Note that I can chmod -x <file> and chmod +x <file> but that does not +change anything. + +I notice that home now contains a "live" directory: /home/live, +ownership lcl:lcl, containing tmp and nothing else. Now that is weird. + +The difference in the root and user prompts is probably related to the +fact that root cannot access the user's X display. I have seen that +sort of thing before when the two have been using different hostnames. +I think that root is now looking at belexeuli:0 whereas the user has for +some reason reverted to localhost:0. Attempts at using the gui by root +throw up protocol errors. + +As you say, a reinstall looks like the best way out. More knowledgeable +people would probably know just where to look for the root of the +problem(s) but even after 21 years experience of Unix and Linux I know +next to nothing about access and security policies. + +Cheers + +Len + + +</PRE> + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="007759.html">[Mageia-discuss] Need help recovering execute permission on local files +</A></li> + <LI>Next message: <A HREF="007761.html">[Mageia-discuss] Need help recovering execute permission on local files +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#7760">[ date ]</a> + <a href="thread.html#7760">[ thread ]</a> + <a href="subject.html#7760">[ subject ]</a> + <a href="author.html#7760">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-discuss">More information about the Mageia-discuss +mailing list</a><br> +</body></html> |
