Have you tried the tar over ssh command that was posted?

The destination machine for backups in this case is S3, so I don't think I can tar over ssh to it. Maybe tar to my s3fs mount would have performed much better than rsync? I'm not sure. Tarsnap is such a breeze I don't think I need to experiment with s3fs any more.

So, at this point, I've basically given up on trying to get the dedicated graphics card to work. But I'm wondering if there's any way to adjust the brightness? If I press the keys to adjust brightness (F2 and F3 for me), the little slider with the brightness icon comes up and the slider reacts accordingly, but the brightness doesn't change at all. Same for going into system settings->screen. I suspect it will be difficult to fix this as well, so hacks are okay too. Like is there an app that will just draw a 50% opacity black box over the entire screen? Once again I'm on ubuntu 11.10 with an hp envy.

I've recently been tasked with administrating a Lenovo X220 laptop with Ubuntu 10.10 installed on it. Updating from kernel 2.6.35-30 to 2.6.35-31 has caused the wireless card to stop working. It works fine when I boot into -30 but it can't even be found with lspci when I boot into -31. I tried compiling more recent drivers for it, but it still doesn't work (its listed as Realtek device 8176 (rev 1) with lspci | grep network in 2.6.35-30). Anyone have any idea what could cause this or how to fix it?

This may just be a typo in your post, but you should be typing: lspci | grep Network or better yet, lspci | grep -i Network Apart from that, when you say that you tried to compile more recent drivers, were you able to compile them successfully and the card just didn't work, or did the compilation failed?

Arch moved pacman 4 out of testing and into core yesterday. I was stuck in dependency hell for a while until I uninstalled yaourt, namcap, yajl, package-query, and pyalpm. If you missed the front page announcement here's a developer's blog post and the wiki page on setting up the gpg keys you'll need to get package signing up and running. https://wiki.archlinux.org/index.php/Pacman-key http://allanmcrae.com/2011/12/pacman-package-signing-4-arch-linux/

Those of you using GNOME 3 and the Shell extensions. I found something I like more than the Window List extension (here). Now I'm looking for the extension that removes the obnoxiously redundant icon in the panel that shows you the active window: I know it exist(ed) because I used to have it installed. Can anyone find it? I can't remember the exact name

I'm running a Linux environment and have currently introduced a new Ubuntu 10.04 box into the system. It's connected to a NIS database on a RHEL server, and authenticates its users through Kerberos (Windows side). Both these services are up and running and work with the other machines in our server park. However, when I try to log into our new box, some specific users are denied access. Kinit grants them a ticket when I supply their credentials in other contexts, but once I try to log them on the system, they're instantly thrown out. I can't seem to find a common link between them either, which is frustrating. It seems to stem from something locally on the box, even though I'm not using any host.allow/deny stuff. Since most of the users actually work, I've been cautious about fiddling with pam.d and nsswitch. As far as I can see the error is not related to ssh either, as they experience the same problem regardless of what means they use to log into the machine. The logs I've been through return the same error: "Failed password", or some sort of "authentication failure". Does this sound familiar to anyone? Any quick suggestions as to where I can continue my troubleshooting? Any known bugs? It's worked out flawlessly on the RHEL servers I've introduced into the mix.

I've been having an issue at work that is really annoying. I have a variety of Linux servers, a few ubuntu and the rest CentOS. When they renew their DHCP lease the dns entry is removed and vanishes, the only way to fix it is to bounce the network interface (ifdown/ifup). Any idea what's going on here? The DNS/DHCP server are Windows Server 2003.

Somebody recommend me a book. I'm supposed to be the "Linux guy" in our office at the moment, but my background is mainly programming on fairly barebones Linux systems. Our customers generally use higher-level distributions such as Ubuntu, so I keep getting asked more "IT" related questions about using Linux that I don't always know the answers to. So I'm looking for a big fat book that I can just read from start to finish and come out with a better general knowledge of linux from a user's perspective. Does such a book exist?

And of course, the only users with issues are actual other people, my admin and test accounts both work perfectly. Argh.

If you're using winbind, have you checked that your idmap configuration is working and can create a map for every user? There's a tool that can dump the winbind cache tdb file which may be useful.

I have very little linux experience and I'm running into a bit of a problem trying to install a program that comes in a tar.gz file. I am running Linux Mint 11 and the program is here: https://www.emitapp.com/ It is a media server that will allow me to stream media to my kindle fire. I've tried googling instructions on how to manually install software outside of the package manager but I'm getting nowhere. Any tips?

What's the best way to diagnose the source of random system freezes? I recently upgraded to Mint 12, and I really like a lot of it so far but It's also given me a bunch of issues and I've formatted/installed several times no trying to solve various problems. A lot of my initial issues seem to be related to ATI drivers, possibly conflicting with Gnome but since uninstalling those as a temporary fix I have not had that problem. I'm now left with one major headache however. My system completely freezes up on a regular basis. It only seems to happen when I am interacting with it, but outside of that I can find no common elements to the events. It can be 10s after logging in or 5 hours. Doing simple things such as using the terminal seems to be less likely to trigger it but does still happen. I suspect it might be related to a persistent system service (ie the GUI) or something as any random interaction, regardless of what is open, or in use. Even just moving the mouse has set it off (actually maybe it's mouse related, I don't recall triggering it with the kerboard and it's always clicking or moving that seems to freeze it). The system locks up and becomes completely unresponsive to any input. Including hotkeys. In the end I am forced to use the physical restart button and even that lags. It's driving me nuts and as much as I have come to like it, making me consider either downgrading or trying something else. So before I give up over what is probably some trivial issue, does anyone have any suggestions on how to go about fixing, or at least working out the cause of it?

The easiset thing might be to just try another distro. Go through the logs in /var/log, starting with /var/log/messages. Can you ssh into the system while it has crashed (ie, is just the desktop locked up)?

I guess I could try it from my phone. Anything special I need to set up? I'd be surprised if I could though, the half second audio loop doesn't inspire confidence. EDIT: Also it seems ubuntu disabled /var/log/messages as of natty by default. As Mint is derivative, so was mine. I found some instructions and have since re-enabled it, so hopefully I get something useful. Most of the other logs however seem to be missing parts from where I have had to hard-reset so I'm not sure if it will help. Shanakin fucked around with this message at 17:05 on Jan 23, 2012 |

You'll need to install the server (sudo apt-get install openssh-server). Apart from that, no - it should automatically start up and configure itself. Don't forget to record the ip somewhere (ifconfig | grep addr) If you can ssh into it, here's a few things to try: - dmesg to check the kernel logs - top or htop to check running processes and resource usage - sudo pkill X or even sudo pkill -9 X to kill and restart the GUI If you can't ssh into (or ping) it it's well and truly wedged.

I haven't found any relevant log entries so far, but I also haven't looked too hard at it yet. The solution was actually really simple. It was tied to a bit of history with out Linux environment. But to spare you the details and keep it short: The passwd-file that was passed out through NIS had older user in it with a password stored. It's basically what the :x: right after every user name in passwd signify -- that there's a password entry for them in the shadow file. Ubuntu didn't like this with my setup, even though our RHEL-servers accepted it just fine. I'm not sure if it's an issue with the PAM stack or what, but everything seemed sound from a logical point of view when I checked. Anyway, I ended up updating the users in the passwd-file, showing username:!!: instead of username:x:. Voila.

More to the point, actually enabling winbind in pam.d/samba helps. It worked with some users because I had already tested those over ssh (which was set up for winbind), I believe. I feel somewhat stupid now.

If the problem is really due to an invalid partition table, you can use dd with if=/dev/zero to clear out the first bit of the drive. I don't recognize the error fsyncing messages...
