• How to get an inactive RAID device working again?

  - by Jonik

  After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

• Disk space profiling in Unix

  - by user1677770

  I'm looking for a tool to summarize how disk space is being used on very large partitions. Our file system is around 950TB, mostly broken up into 20TB partitions. There are some really nice graphical tools for visualising these file spaces: http://www.disksavvy.com/disksavvy_screenshots.html http://methylblue.com/filelight/ But I'm really not sure how well they will scale. Does anybody have any experience of these tools and can make any recommendations? Even something that parses and summarises a really big du output would be a good start.

• Force gdm login screen to the primary monitor

  - by JIa3ep

  I have two monitors attached to my video card. Primary monitor has a resolution equal to 1280x1024 and second has 1920x1200. My gdm login screen always appears on the second monitor even if it is switched off. My question is how to force gdm to show login screen always on primary monitor with resolution 1280x1024? I use Ubuntu 10.04.

• How can I merge the gnome clipboard and the X selection?

  - by TREE

  I'm constantly frustrated by the two separate clipboards in X/Gnome. I'm constantly doing things like control-C to copy, and then middle-click to paste, and getting the wrong data. Or select something, then go where I want to paste it, and selecting what I want to paste over, only to lose my first selection! Is there any way to merge these two clipboards?

• Make puppet agent restart itself

  - by SamKrieg

  I've got a file that notifies the puppet agent. In the network module, the proxy settings are included in the .gemrc file like this: file { "/root/.gemrc": content => "http_proxy: $http_proxy\n", notify => Service['puppet'], } The problem is that puppet stops and does not restart. Aug 31 12:05:13 snch7log01 puppet-agent[1117]: (/Stage[main]/Network/File[/root/.gemrc]/content) content changed '{md5}2b00042f7481c7b056c4b410d28f33cf' to '{md5}60b725f10c9c85c70d97880dfe8191b3' Aug 31 12:05:13 snch7log01 puppet-agent[1117]: Caught TERM; calling stop I assume the code does something like /etc/init.d/puppet stop && /etc/init.d/puppet start Since puppet is not running, it cannot start itself... it kind of makes sense. How to make puppet restart itself when this file changes? Note that this file may not exist as well.

• Recovering/Creating NewWorld Partition on Mac G4 (PPC) after botched Debian Install

  - by Luis Espinal

  I was trying to install Debian 5.04 on a Mac G4, and in typical geek tradition, I didn't RTFM. During installation, I nuked all existing partitions, creating new to my liking. But as I learned later during the installation process, yaboot needed a NewWorld partition, so I can't boot the installation. I don't have any OSX CDs with me (this is a used G4 I purchased of craigslist) with which to create a HFS partition. I've re-run the Debian installer, which lets me create a partition that is supposed to be of type 'NewWorld', but the installer does not seem to like it or recognizes it. Any ideas how to proceed from here? Thanks.

• Where is php executable on Ubuntu?

  - by user601L

  I have installed apache and php. I know php works as I have tested a simple php file on apache server. I'm writing a simple webserver which should be able to process php files. So what I want to do is once I get a request for a php file, something like 'exec php test.php' and get the output and pass it to the client. As I'm not much into Ubuntu, I don't know where is the php executable (should be in \bin right?) to do it. But there is no php file inside \bin or \usr\bin. When I run 'which php' it shows nothing. How do I do this?

• Where is the xorg.conf file in Karmic Koala (Ubuntu 9.10) ?

  - by jfmessier

  I am trying to change this xorg.conf file that I used to modify under Ubuntu 9.04, so it can have the higher resolutions of my monitor. Under 9.04, the monitor was unknown, and I had to key in all resolutions in the file, and although it is found under 9.10, 9.10 does not have the highest resolution that My monitor can sustain. How can I change such setting ? Is xorg.conf moved, or replaced ? Merci :-) JF

• Making libmagic/file detect .docx files

  - by Jonatan Littke

  As seen elsewhere, docx, xlsx and pttx are ZIPs. When uploading them to my web application, file (via libmagic andpython-magic) detects them as being ZIP. I store the contents of the file as a blob in the database, but naturally I don't want to trust the user with what kind of file type this is. So I would like to trust file for and automatically generate a filename during download. I know one can modify /etc/magic but the format (magic(5)) is way too complicated for me. I found a bug report on the issue at Debian bugs but since it's from 2008 it doesn't seem to be fixed any time soon. I guess my only other alternative is to indeed trust the user (but still store the contents as a blob) and only check the file extension based on the file name. This way I can disallow some extensions and allow others. And when the user re-downloads his file, he can have it in whatever way he uploaded it. But this solution is insecure if the file is shared with others, since you can simply rename the file to allow uploading it. Any ideas? Lastly, I found a list of magic numbers for docx etc, but I'm unable to convert these into the magic(5) format.

• How to run Firefox jailed without serious performance loss?

  - by Vi

  My Firefox configuration is tricky: Firefox runs at separate restricted user account which cannot connect to main X server. Firefox uses Xvfb (virtual "headless" X server) as X server. x11vnc is running on that Xvfb. On the main X server there is vncviewer running that connect to this x11vnc On powerful laptop (Acer Extensa 5220) it seems to work more or less well, but on "Acer Aspire One" netbook it is slowish (on a background that firefox is loaded with lots of extensions). How to optimise this scheme? Requirements: Browser cannot connect to main X server. Browser should be in chroot jail (no "suid" scripts, readonly for many things) Browser should have a lot of features (like in AutoPager, NoScript, WoT, AdBlockPlus)

• Home server - HP Proliant Microserver - Software and setup - OS on USB stick? [closed]

  - by Lloyd Watkin

  I've just purchased a HP ProLiant Microserver for home use. I want to set up with web server, samba shares, the usual stuff. My question is really about system setup. It has an internal USB socket so I've attempted to install a copy of Fedora 14 onto it. I turned off X/Gnome, but it still ran like a pig. I've now put the OS on one of the internal disks (250Gb, 7200rpm), but I was wondering if there was a way to utilise the internal USB to give me better power-saving allowing the hard drives to be shut down when not in use. How would you set this server up? I'd rather not go to the extra cost of an SSD right now, but if that's the best way then so be it.

• install grub on disk image

  - by Dima

  I have disk image with 2 partitions: Partition 1 has cramfs file system (read only). This partition contains all system files of the OS Partition 2 has ext3 file system. This partition has only configuration files that may be changed. How can I install GRUB1 boot loader on MBR. I tried to copy first 446 bytes of my hard disk and copy GRUB files to the /boot directory on the 1st (cramfs) partition. I cannot use grub-install because I have disk image and not disk itself. Any ideas?

• Restrict SSH user to connection from one machine

  - by Jonathan

  During set-up of a home server (running Kubuntu 10.04), I created an admin user for performing administrative tasks that may require an unmounted home. This user has a home directory on the root partition of the box. The machine has an internet-facing SSH server, and I have restricted the set of users that can connect via SSH, but I would like to restrict it further by making admin only accessible from my laptop (or perhaps only from the local 192.168.1.0/24 range). I currently have only an AllowGroups ssh-users with myself and admin as members of the ssh-users group. What I want is something that works like you may expect this setup to work (but it doesn't): $ groups jonathan ... ssh-users $ groups admin ... ssh-restricted-users $ cat /etc/ssh/sshd_config ... AllowGroups ssh-users [email protected].* ... Is there a way to do this? I have also tried this, but it did not work (admin could still log in remotely): AllowUsers [email protected].* * AllowGroups ssh-users with admin a member of ssh-users. I would also be fine with only allowing admin to log in with a key, and disallowing password logins, but I could find no general setting for sshd; there is a setting that requires root logins to use a key, but not for general users.

• Cracking WEP with Aircrack and Kismet

  - by Jenny

  Just a minor question, but I notice with aircrack when it lists networks, it does not list the encryption type of each network. Which seems fair enough, as you can use Kismet, however on my machine when I end kismet and the server, the monitor interface is not removed and I cannot remove it manually, which screws with aircrack. SO, is kismet needed to view encryption types of networks, and if so how do you use it peacefully in unison with aircrack?

• =?UTF-8?B??= in Emails sent via php mail problem

  - by Camran

  I have a website, and in the "Contact" section I have a form which users may fill in to contact me. The form is a simple form which action is a php page. The php code: $to = "[email protected]"; $name=$_POST['name']; // sender name $email=$_POST['email']; // sender email $tel= $_POST['tel']; // sender tel $subject=$_POST['subject']; // subject CHOSEN FROM DROPLIST, ALL TESTED $text=$_POST['text']; // Message from sender $text.="\n\nTel:".$tel; // Added to message to show me the telephone nr to the sender at bottom of message $headers="MIME-Version: 1.0"."\n"; $headers.="Content-type: text/plain; charset=UTF-8"."\n"; $headers.="From: $name <$email>"."\n"; mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $text, $headers, '[email protected]'); Could somebody please tell me why this works most of the time, but sometimes I receive email whith no text and the subject line showing =?UTF-8?B??= I use outlook express, and I have read this http://stackoverflow.com/questions/454833/system-net-mail-and-utf-8bxxxxx-headers but it didn't help. The problem is not in Outlook, because when I log in to the actual mailprogram where I fetch the POP3 emails from, the email looks the same. When I right click in Outlook and chose "message source" then there is no "From" information. Ex, a good message should look like this: Subject: =?UTF-8?B?w5Z2cmlndA==?= MIME-Version: 1.0 Content-type: text/plain; charset=UTF-8 From: John Doe However, the ones with problem looks like this: Subject: =?UTF-8?B??= MIME-Version: 1.0 Content-type: text/plain; charset=UTF-8 From: As if the information has been lost somewhere. You should know also that I have a VPS, which I manage myself. I use postfix as an emailserver, if thats got anything to do with it. But then again, why does it work sometimes? Also another thing that I have noticed is that sometimes special characters are not shown correctly (by both Outlook and the webmail). For instance, the name "Björkman" in swedish is shown like Björkman, but again, only sometimes. I hope anybody knows something about this problem, because it is very hard to track down for me atleast. If you need more input let me know.

• NFS mount mounted inside another NFS mount disappears randomly

  - by espenfjo

  I have quite an odd issue where my nested NFS mounts just disappear randomly from time to time. The fstab entries look somewhat like this: nfs:/home /home/nfs rw,hard,intr,rsize=32768,noatime,nocto,proto=tcp 0 0 nfs:/bigdir /home/bigdir nfs rw,hard,intr,rsize=32768,noatime,nocto,proto=tcp,bg 0 0 The issue is that from time to time the "/home/bigdir" folder will be empty, even though mtab think that the share is still mounted. nfsstat et. al. do also think the share is still mounted. Only thing that works is by unmounting, and then (re)mounting the bigdir share. The server side is a NetApp. The client side is RHEL5.5, 2.6.18-194 kernel (Yes, I know 5.8 is out, but as far as I can see there are no erratas for this particular issue). I can use various hacks like automount, or mounting it to another path and then using --mount bind, but I would like to fix the underlying issue. -- Best regards Espen Fjellvær Olsen

• How to change a physical partition system to LVM?

  - by Daniel Hernández

  I have a server with Debian that have 3 physical partitions covering all the disk: boot, root y swap. Now I want to replace that partitions with LVM partitions. I know how install Debian with LVM at beginning, but in this case I can't install the system at beginning because the provider gets me a server with remote access and the system installed in this way. How can I change that partitions using only an ssh connection and possibly other remote server where to put some temporal data?

• How to add a broadcast address to loopback with ifconfig on a OS/X?

  I am trying to use ifconfig to turn on broadcast on my loopback interface. It currently reads: lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 As you can see, no broadcast address! :( :( :( I tried this on OS/X but it did not work and it did not give any error or feedback: ifconfig lo0 broadcast 127.255.255.255 Any guru would know that? I have one server that sends one packet. I have two clients running on the same machine as the server. I need them to pick up the packet WITHOUT having to force the server to send it twice.

• Mount "Macrium Reflect" on a partition, boot from there ?

  - by b e

  Can Macrium's Reflect recovery CD be mounted/used with GRUB ? If the cd can be 'put' (loaded/mounted/...) in a partition, then the only disc needed would be the actual recovery disc, which could be on an external hard drive, or even on the same machine in another partition, thus allowing on to recover using only what's on the machine itself. I have WXPpro and Xubuntu8.04 double mounted, really happy with them together, use each right now to fix problems with the other when they come up. Also have a partition for the Reflect CD, but I just can't get it to load from Grub, which would be great... Thanks for any thoughts, probably someone has already done this I know !

• Middle mouse click in VirtualBox (Vista host, Debian guest)

  - by Ken

  I'm running Virtualbox on Windows Vista. I have a Microsoft USB mouse (it says "Comfort Optical Mouse 3000") with left and right buttons, and a mousewheel in the middle. If I press down on the wheel, it pretty obviously makes a "click". I'm running Debian inside Virtualbox, and it's working great, but middle-mouse-click does nothing. Left and right click, and scrolling with the wheel, work fine. Is there any way to get middle-mouse-click to work in my virtual machine?

• Disabling networkmanager for a specific interface

  - by bdonlan

  I'd like to do some experimentation with hostap without disabling my primary wireless interface. How do I tell networkmanager to keep its hands off a specific interface or interfaces while allowing it to continue managing all other interfaces normally? I'm using Ubuntu 9.04. (Wasn't sure if this should go on superuser or serverfault, as networkmanager isn't much of a 'server' tool - if it belongs on serverfault please feel free to move it) Edit: I've tried adding this to /etc/network/interfaces: allow-hotplug wlan2 iface wlan2 inet static address 192.168.49.1 netmask 255.255.255.0 But this has no apparent effect, even after restarting NetworkManager. Here's my /etc/NetworkManager/nm-system-settings.conf: [main] plugins=ifupdown,keyfile [ifupdown] managed=false Edit[2]: Looks like I needed to restart nm-system-settings, then NetworkManager.
