The prompt difference may be simply that root's +</I>><i> prompt is +</I>><i> no longer the same as a user's prompt. It is set by a config +</I>><i> file for +</I>><i> each user. You can see the code for it by typing "echo $PS1" +</I>><i> In my +</I>><i> case, that gives "[\u@\h \W]\$" The \h puts in the hostname. +</I>><i> You can +</I>><i> change it for the current session by typing at the user prompt: +</I>><i> +</I>><i> PS1="[\u@\h \W]\$" +</I>><i> +</I>><i> You can make that permanent by putting it in your +</I>><i> .bash_profile, where +</I>><i> it should override the other at your next login, but really, +</I>><i> it is only +</I>><i> a workaround. +</I>><i> +</I>><i> With so many issues, I would do a full reinstall, but more +</I>><i> knowledgeable +</I>><i> people tell me it is the easy way out. +</I>><i> +</I>><i> HTH, +</I>><i> +</I>><i> Doug. +</I>><i> +</I>><i> Yes, all the commands have execute permission. I have been using +</I>><i> my local bin directory for years and I have never had execute +</I>><i> refused so this must reflect some deep system level screwup +</I>><i> relating to lcl and maybe something in pam.d. That is unknown +</I>><i> country for me. +</I>><i> Until yesterday there was no lcl group, only user lcl. The group +</I>><i> for lcl was live, which I have +</I>><i> removed from my group list. live was my primary group, now it is +</I>><i> lcl which I added yesterday. Ownership of my files is now lcl:lcl +</I>><i> and in /home/lcl/bin the permissions are nearly all 755. +</I>><i> Note that I can chmod -x <file> and chmod +x <file> but that does +</I>><i> not change anything. +</I>><i> +</I>><i> I notice that home now contains a "live" directory: /home/live, +</I>><i> ownership lcl:lcl, containing tmp and nothing else. Now that is +</I>><i> weird. +</I>><i> +</I>><i> The difference in the root and user prompts is probably related to +</I>><i> the fact that root cannot access the user's X display. I have +</I>><i> seen that sort of thing before when the two have been using +</I>><i> different hostnames. I think that root is now looking at +</I>><i> belexeuli:0 whereas the user has for some reason reverted to +</I>><i> localhost:0. Attempts at using the gui by root throw up protocol +</I>><i> errors. +</I>><i> +</I>><i> As you say, a reinstall looks like the best way out. More +</I>><i> knowledgeable people would probably know just where to look for +</I>><i> the root of the problem(s) but even after 21 years experience of +</I>><i> Unix and Linux I know next to nothing about access and security +</I>><i> policies. +</I>><i> +</I>><i> +</I>><i> +</I>><i> Maybe it was somehow mounted with the -noexec flag? +</I>><i> +</I>><i> Alejandro. +</I>><i> +</I>><i> +</I>mtab contains this entry: + +/dev/sda6 /home ext4 +rw,nosuid,nodev,noexec,relatime,user_xattr,barrier=1,data=ordered 0 0 + +fstab had: +# Entry for /dev/sda6 : +UUID=341956e4-fddb-45a6-a191-4c912328ec7a /home ext4 user,defaults 1 2 +none /proc proc defaults 0 0 + +I have removed the "user," because it does not tally with my other mga2 +workstation. +That does not have noexec against /home. + +About to reboot. + +Thanks for the pointer. + + + + + +-------------- next part -------------- +An HTML attachment was scrubbed... +URL: </pipermail/mageia-discuss/attachments/20120611/d4771dee/attachment-0001.html> +</PRE> + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="007761.html">[Mageia-discuss] Need help recovering execute permission on local files +</A></li> + <LI>Next message: <A HREF="007763.html">[Mageia-discuss] Need help recovering execute permission on local files +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#7762">[ date ]</a> + <a href="thread.html#7762">[ thread ]</a> + <a href="subject.html#7762">[ subject ]</a> + <a href="author.html#7762">[ 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> |
