On one server, we've given one account sudoers access to ONLY restart Tomcat username localhost=/etc/init.d/tomcat5 stop, /etc/init.d/tomcat5 start, /etc/init.d/tomcat5 restart However, when he tries to sudo any of these commands, he gets "username is not allowed to run sudo on server. This incident will be reported" Am I missing something?

+1 for spideroak. Also, your content is encrypted on the servers. Now I have a question. I'm somewhat new to Linux desktops, but have been running Linux servers for a while. I'm using XFCE on a laptop that is usually docked to a docking station with two monitors. When I undock and use the built in display, the bottom panel is all the way toward the right, and the top panel is "panel 3", in other words, its the panel that;'s on my 2nd display when docked. Is there any way I can set up an alternate config for when the laptop is undocked so this looks right and acts like I want?  EDIT: Tables

I have a desktop running Fedora 17 with XFCE and every now and then the bottom task bar panel thing decides it won't let me click on it to select windows any more. Alt+Tab works but the panel doesn't. When that starts happening it also starts blinking the window icons as if to indicate activity in a window. I haven't found a way to fix this except for restarting X. Is this just a bug or did I break something? Using xfce4-panel-4.8.6-4.fc17.x86_64.

I have an Arch linux install on a VM, and I broke something (long story) and had to revert to a snapshot that was from back in July 2012. Now I can't do a system update (pacman -Syu) without literally everything breaking. I either get all these "call to execv failed" messages where absolutely nothing works anymore and the system can no longer boot, which seems to be related to updating glibc, or if I tell it not to update glibc until I update everything else, I get a "/lib/libc.so.6: version GLIBC_2.17 not found" message and if I reboot a ton I can eventually update GLIBC but it does the same "call to execv" error. Is there any decent procedure for updating from an old install that doesn't destroy my entire system? Most of the things I found online were telling people they should have updated every week or that something happened because they used the force command (I didn't do that) so I'm confused. I've never had this issue before but apparently many things changed in Arch with library symlinks or something last year so I'm guessing that's breaking everything. Or if an 8 month old arch system is considered doomed, is there a good procedure for copying out all my installed packages and configuration files so I can start a new one?

ExcessBLarg! posted:That said, gcc historically hasn't cared about link order for dynamic libraries. So if you have a libbar.so, "gcc-4.4 -o foo -lbar foo.c" works fine. However at some point since GCC 4.4, it added the single-pass ordering constraint for dynamic libraries as well, hence the need to change the order. Honestly I have no idea why, this is the first I've heard of it. Default behavior in the linker was --no-as-needed, which means any time it saw a library listed on the command line, it added a DT_NEEDED entry for it in the final executable/library, even if it wasn't actually needed. The end result is that a bunch of stuff linked to a gigantic pile of libraries that they never actually used, which slowed startup times and wasted memory. Ubuntu modified gcc to always pass --as-needed to the linker, which means you have to follow the usual single-pass link order rules for dynamic libraries.

Is there any way to reinstall/fix df without having to completely reinstall the operating system? It broke the other day, not sure at all why. It's about 12 gig under. I'm on Centos 6, kernel version is 2.6.18-308.8.2.el5.028stab101.1. Here's the output of df -h: code:code:

River posted:Is there any way to reinstall/fix df without having to completely reinstall the operating system? Broken how? It looks fine. That kernel version also looks like CentOS 5. df is a (very) simple utility that just asks the filesystem. Your 'du' reads a file that existed temporarily, some tarball in /tmp, open crap in /proc/*/fd, potentially crossed filesystem boundaries into /boot, and who knows what else. It's no more or less "true" than df. They're different tools for different purposes. You should probably exclude /proc, /dev, /tmp, and anything else which may be in RAM, otherwise you've no hope of results lining up. Additionally, any large deleted files held open? uG posted:

Yes it's running on OpenVZ.evol262 posted:Broken how? It looks fine. That kernel version also looks like CentOS 5. It's CentOS 6. Might be some OpenVZ fuckery giving me an older kernel, I'm not sure. I know that df is off because if I were to clear out everything from my personal directories (where basically all my poo poo is) it'd read something like 300kb total used - which doesn't make sense since Centos alone is a few hundred megabytes. I referred to the du spitout as 'true' because it represents basically what I'm actually using and isn't 12gb off. How do I check if there's any large, undeleted files held open? I've rebooted several times since this happened - wouldn't they be gone by now?

I want to make my XFCE look more like the OS I am familiar with, windows 7. I dont care enough to go off and install a windows theme, just want similar button placement. I arranged the panel and have something similar, but is there anything similar to a 7 style dock/application switcher? Also, what about a menu similar to 7? **edit** I discoverd DockbarX, and apparently it should work with XFCE. I am running Xubuntu 12.10. I installed dockbarx, and when I choose it from the menu it will load vertically along the left side of my screen, but that is not where I want it. I can not figure out how to add this to my panel. edit #2 - I think the problem I am having with DockbarX and XFCE might be related to running XFCE 4.10, I really don't know yet. I just know when searching for XFCE 4.10 and DockbarX google doesn't return much of anything, but it does return a bit for XFCE 4.8 + DockbarX. So, is it possible/realistic for me to downgrade to XFCE 4.8? Not Wolverine fucked around with this message at 19:40 on Feb 24, 2013 |

Just for a lark, try doing this: tune2fs -l </this/partition/> look for "Reserved Block Count" Many file systems will reserve space so that a normal user cannot fill the root partition to 100%, causing some issues. I just had to deal with finding some extra space that was "hidden" and found it with this. Not that reserving some emergency space isn't a good idea. But it might help solve the mystery.

The standard way to measure idle time is using the completely undocumented IDLETIME XSync counter. Because I'm feeling generous today, here's a simple example program: http://magcius.mecheye.net/random/xalarm.c Compile it using the line on the top, and then run: $ ./xalarm 2000 or so on to wait for 2000 milliseconds of idle time. You can use this to loop with bash. It doesn't actively use any resources -- it simply waits in poll for the event to come from the X server.
