So this is a fairly simple question and I'm sure the answer is completely obvious. Forgive me, I'm a newb. I just installed the newest Ubuntu server edition. I transferred over some files into a directory I created called /share. I made sure to chmod the directory and all the sub-directories as 777. Today I decided to delete some redundant files off the transfer. Everything was going fine until I got to my folder /share/Videos/TV. All of the files and directories in there refuse to be deleted. Every time I try and delete them I get " 'Failed to remove [file]': Read-only file system" I went back and tried to chmod the files again, and I get "changing permissions of '/share/Videos/TV': Read-only file system". These are any file that's stored in this directory, whether it's an AVI or txt file. All the other folders and files in /share can be deleted or modified just fine. What simple little thing am I missing?

What output do you get for: mount cat /etc/fstab df /share/Videos/TV If you don't see anything about ro in /etc/fstab you can try looking at dmesg or /var/log/messages to figure out why it was mounted read only. Also chmoding everything 777 is really unnecessary, you might want to read up on file permissions. SynVisions fucked around with this message at 16:16 on Jul 23, 2008 |

Loaded Xubuntu onto my laptop, everything but sound works. aplay -l shows the sound device and so does lspci -v. However, the "master" volume slider just doesn't work, just PCM. I've tried all the various things suggested on the web, including installing the latest alsa drivers and adding a line to a file that's supposed to activate my sound. It's a Toshiba laptop with an ATI motherboard running a Realtek ALC861 sound chip. Any ideas?

Not sure where exactly this fits, but I need a suggestion for a way of implementing a shutdown procedure for power failure. I have a Belkin UPS with usb, and my plan was to have it hooked up to my windows pc and have it do the monitoring. I noticed in the power options control panel in windows that it can execute a program at a certain battery level. My idea was to execute some kind of script at critical battery level to send a shutdown command to the linux box. The only question is how. I may be re-inventing the wheel here as I haven't looked real hard at a linux native management solution, but I feel like I could learn a lot trying it this way. So where should I start? I'm totally talking out of my rear end, but I was thinking of possibly having a port triggered on the linux box by a batch script on the windows box? Running Ubuntu if it matters.

Just write a script that SSH's into the linux box and issues a shutdown. You can download cygwin if you want, but I'd be surprised if this wasn't possible with a regular windows SSH client like putty. Just make sure you generate a key so you can use public key authentication.

hello, i have recently bought a radeon HD4850 and have been using Ubuntu now for the past three years but for the holidays i have been booting into windows for gaming pretty much non stop, now i have returned to uni i noticed that compiz is not working. (I upgraded the graphics card abou a month ago and haven't booted into ubuntu since.) i was looking at the work around s but they appear to have a few glitches and blips, i really don't want my OS dying after finishing an assignment. my question is how long would your estimate be for the card to be added to supported cards list in the ubuntu repositories? ( i have a feeling that the answer may be "how long is a piece of string?" : ) i know the problems is the graphics because when i run compiz in the terminal it notes that my graphics card doesn't exist in the database

Im about to reinstall Jinzora because I recall there being an alternate way the database/interface is set up but before I do, what are some other good music streaming packages with GOOD interfaces? Like right now, I have three folders with a bunch of folders (each one an album) underneath, each containing music and I want Jinzora to look exactly like that file structure. Which it doesn't, and that makes browsing a complete bitch. also - does anyone have a link to that "cool stuff to do with two nics cards" article that was on slashdot or digg a while back? rugbert fucked around with this message at 16:20 on Jul 26, 2008 |

I'm having some issues with my lvm, hoping for some help. Running Ubuntu 8.04; LVM2; ReiserFS I had 2 drives in my lvm which started to get full. So I decided to pick up a new drive. My motherboard only has 2 SATA controllers, so I also picked up a PCI -> SATA controller. Fast forward about 2 weeks, I start to get some really bad performance issues on the drive. My assumption is that the first 2 disks finaly filled up and its starting to use the new drive. I'm unable to copy any (new)file larger than 56.9MB. Any file created before the new drive was added to the LVM is fine. This is both when doing a copy from 1 folder to the next, but also during scp transfers. My first assumption is that PCI really wasn't the brightest idea, so I ordered a new PCI-e -> Sata. The LVM detects the drive just fine, but the same issue. So now, I'm assuming maybe the drive is messed up. I run a reiserfsck, and it detects no errors. I decide to try and remove the drive from the lvm, and durring the resize_reiser I get an error about bad blocks. So now, I'm wanting to pull the new drive from the lvm, and I'll create a new lvm device with the drive for testing before I RMA the drive. Since I cannot resize the reiserFS; How can I pull the drive from the LVM? Any other ideas about the drive/LVM that I might of missed?

I'm in a very basic networking class online right now, and one of the assignments is to design a network (on paper). The setup is that there are 4 computers, all of them Pentiums built in 1999 and running Windows 95, only one of which currently has access to the internet. The proposal also calls for it to be pretty cheap, so I've been doing some looking around at Linux for the software. So far, I'm thinking of RedHat as the main OS, and OpenOffice to replace WordPerfect. The existing network also uses MS Access for files; would Samba or PostgreSQL + ReKall work better for that? The professor hasn't given us specifics on what kind of computers we're working with, and probably isn't going to; this is more of a theory / setup exercise than an actual "putting together a network" assignment, and I'm a little paranoid I'll accidentally put in an application that won't run on the machines.

I'm not sure if the following will give me a coaster or not, so I better ask you guys before I try out: find foldername/ -name *.gpg -ctime -5 -print0 | xargs -0 growisofs -M /dev/cdrw -r '{}' \; so all those files named *.gpg changed five days ago or fewer will get burned as a session to my DVD-R. That's the idea.

Gotta quote the *.gpg lest your shell expand it for you  And, what's the '{}'\; part for? That's usually found when using find -exec, and AFAIK has no meaning when used with xargs, although I could be misremembering things and xargs accepts it too. Never used growisofs so no idea if those are the right args otherwise

Running Ubuntu if it matters. Here's a quick rundown to get you started, I had a setup similar to this when I had a lovely powerwave UPS. You'll have to lock it down though. 1) Get Putty, PuttyGen and Plink from Here. 2) Use Puttygen to create a ssh key without a passphrase. 3) Create a new user on the linux box and give them that key (/home/<user>/.ssh/authorized_keys) 4) Edit the /etc/sudoers file to give that user the shutdown command only. (<user> ALL = NOPASSWD: /sbin/shutdown) 5) Create a Putty Session with the username and key you created, then save it as something like "shutdown" 6) Write a .bat script with something like (plink shutdown sudo shutdown -h now) in it.

I'm going to feel pretty dumb if this is obvious, but I'm playing around with distributions and I wanted to give Ubuntu Server a try. Coming from OpenSuse, I found it nice to be able to configure common items through Yast via the commandline. Is there something similar in Ubuntu? I'm fine with editing config files by hand, but Yast was nice for things like firewall setup. I'm working on headless systems mostly so I'm looking specifically for cmdline tools.

Not sure exactly how Yast configures things in a way that differs from editing config files; Debian-based systems use the apt suite of tools (apt-get, aptitude, dpkg, etc). One feature of apt is that a package manager can define a configuration script to be run at install time (the system that handles this is called 'debconf') and so instead of just getting the usual installation output, the sysadmin will get a curses-based series of dialogs asking e.g. what the root MySQL password should be (for mysql-server) or how Postfix should be set up, as a standalone host / full mail server / satellite host / etc (for postfix). You can then run dpkg-reconfigure <packagename> at any time post-installation and it will re-run those dialogs, letting you re-do the configuration. No idea if this overwrites manual changes done during the interim -- I'd expect so. I'm guessing that's the sort of thing you're talking about? Only some Debian packages have this sort of thing defined, but I'd expect it to be the same with Yast: only when someone has taken the time to define these config question-answer patterns will you get to use them. If you mean non-package-related stuff like your firewall example, I don't know of any built-in programs that give you a curses-based interface to configurations like that, but I don't look for that either, being a fan of config files

That's pretty much where I was going with it, thanks. I'm plenty OK with text based config files but there are times where I feel it is nice to get a window with some checkboxes, but that could just be me having spent the last ten years as a Windows developer

Then I installed it on my desktop and left windows XP as the primary OS. I don't seem to be able to connect to the internet from freeBSD but I can from windows (although for some reason it seems to take a second time in a row booting into windows for it to work, when I switch from freeBSD to windows I can't connect to the internet) Here's pictures of what I get from ifconfig laptop, working internet:  Click here for the full 1280x960 image. desktop, no internet:  Click here for the full 1280x960 image.
