• Change popup format for Kopete in Gnome (Ubuntu 10.04)

  - by HorusKol

  After trialling Empathy which was included with Gnome/Ubuntu 10.04 I decided to go back to Kopete since I was losing chat messages. However, for some reason, Kopete is now displaying all popups in a big, ugly window with four options (ok, cancel, view, ignore, or something like that) that actually all seem to do nothing. I tried looking for options in Kopete to change the popup style to the nicer Gnome style one which goes up in the top-right of my desktop, but it doesn't seem to be possible with this release. So I had to resort to removing all popup messages from Kopete to prevent my screen being taking over by a popup requiring action for every incoming chat message. Unfortunately, this now means that I do not get any notifications when people message me - and so I can go a couple of hours without realising that they did. Anyone know how to get the nice, unobtrusive popups working in this version?

• Ubuntu: Is there a good tabbed PDF viewer?

  - by Frank

  Is there a good non-bloated PDF viewer for (Ubuntu) Linux that supports tabs? I don't want to use Acrobat Reader because it is slow and takes much memory, and my computer isn't the fastest. I know the alternative readers evince and foxit, but they don't support opening different PDF files in tabs. (foxit has that feature on Windows, but the Linux version 1.1, which I just tried, doesn't have it.) For evince, I know many people would like this functionality, but they get ridiculed by Ubuntu people (see here), who say that tabs are the task of a window manager. If that is the case, how can I put all evince windows into one in GNOME?

• How to configure autofs5 timeout on per-filesystem basis?

  - by Norman Ramsey

  Because of a show-stopping bug in Debian autofs 4, I just upgraded to autofs5. It is not honoring the timeout option in my auto.master file: /var/autofs/removable /etc/auto.removable --timeout=2 I use this map for thumb drives and so on; I don't want a general default timeout of 2 seconds. I did some digging and although the --timeout option worked in autofs 4, and it appears in some examples on the Web, it is not actually sanctioned (or even mentioned) in the documentation for the auto.master file. So I don't feel I can report the problem as a bug. How can I get autofs5 to timeout after 2 seconds only on designated filesystems? Update: I am using a Debian-packaged autofs5, version 5.0.4-3.2.

• Free, Linux-based rescue CD for Windows machines

  - by Adam Matan

  Hi, Too often, I'm being called to help a friend who screwed a Windows machine by some creative methods. Th usual remedy is backing up the hard drive contents and reinstalling. Right now, this is done by removing the defected hard drive to my machine. I figured out that using a rescue disk running some version of Linux might ease the process. I'm looking for: NTFS access Partition tools Large variety of drivers (Network, Hard drives, etc.) GUI and some rescue wizards a great plus. Any ideas? Adam

• How do I install something from source and make it available to root?

  - by pwny

  I have a CentOS VM and I need to install the latest version of Ruby on it. Unfortunately, yum only makes Ruby 1.8.6 available so I'm trying to install Ruby from source. Here's what I'm using: cd /usr/src sudo -s wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p125.tar.gz tar -xvzf ruby-1.9.3-p125.tar.gz cd ruby-1.9.3-p125 ./configure make && make install The problem is that once that's done, I can only use Ruby as a regular user but I need to use it as root to install some gems. For example, as a regular user I can do ruby -v and it works but sudo ruby -v outputs bash: ruby: command not found. What am I missing to make stuff I install from source available to all users?

• Make GRUB automatically boot Ubuntu

  - by Matt Robertson

  I am running a dual-boot with Ubuntu (10.10) and Windows 7. Recently I edited my /boot/grub/grub.cfg file to only show one version of Ubuntu (as opposed to several kernel versions) and Windows, simply by commenting out all other menu entries. My question is if I can edit GRUB to just boot a specific entry automatically. I tried removing all other menu entries, but GRUB still showed the menu with only one entry. I've also considered just setting the timeout to either 0 or 1 second, as this would basically achieve the same thing. What is the best way to do this?

• Merge Visio files

  - by David Stratton

  I know I can do this manually by using copy/paste but I'm looking for a simpler way. Does anyone know of a quick and easy way to merge Visio documents? I have several Visio vsd files, all of which are the same internal document type (Flowchart - US Units). Each of these has between 1 and 15 pages. I'd like to combine them all into one Visio file. I'm using Visio for Enterprise Architects (11.4301.8221) so if there's a procedure for doing it in that version, that's what I'm looking for, but a 3rd party tool or a macro would work as well.

• The application attempted to perform an operation not allowed by the security policy

  - by user16521

  I ran this command on the server that has the share of code that my local IIS site set to (Via UNC to that share): http://support.microsoft.com/kb/320268 Drive:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe -m -ag 1 -url "file:////\\computername\sharename\*" FullTrust -exclusive on (obviously I replaced Drive with C, and the actual computername and sharename with the one I'm sharing out). But when I run the ASP.NET site, I am still getting this runtime exception: Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

• What is it that automatically checks config changes (such as those in /etc) into git?

  - by Brandon

  I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

• Virtualizing OpenSolaris with physical disks

  - by Fionna Davids

  I currently have a OpenSolaris installation with a ~1Tb RaidZ volume made up of 3 500Gb hard drives. This is on commodity hardware (ASUS NVIDIA based board on Intel Core 2). I'm wondering whether anyone knows if XenServer or Oracle VM can be used to install 2009.06 and get given physical access to the three SATA drives so that I can continue to use the zpool and be able to use the Xen bits for other areas. I'm thinking of installing the JeOS version of OpenSolaris, have it manage just my ZFS volume and some other stuff for work(4GB), then have a Windows(2GB) and Linux(1GB) VM (theres 8Gb RAM on that box) virtualised for testing things. Currently I am using VirtualBox installed on OpenSolaris for the Windows and Linux testing but wondered if the above was a better alternative. Essentially, 3 Disks - OpenSolaris Guest VM, it loads the zpool and offers it to the other VMs via CIFS.

• Possible to write an implement of RAIDZ or RAIDZ2 for the MD driver in the Linux kernel?

  - by Pharaun

  I am curious on if it is possible to have an implement of RAIDZ and/or RAIDZ2 in the MD driver in the Linux kernel? From my understanding of it is that the RAIDZ version is equivalent to a RAID 5, and that a RAIDZ2 is equivalent to a RAID 6. The main difference is that the stripe size can be variable for RAIDZ as opposite to RAID 5/6 from my understanding, which helps performance. So what I am wondering is would it be possible to add this performance enhancing technique to RAID 5 & 6 in the MD driver in the kernel? Or is it tied too closely to how the ZFS works?

• Is there a way to run virt-manager on Windows?

  - by slm

  We've been using KVM for almost a year strictly on CentOS 5.x as the KVM host, with Fedora and Ubuntu workstations accessing the KVM host and its guests using virt-manager, virt-viewer, and ssh. Is anyone aware of a way to access the KVM host using virt-manager from a Windows workstation? We have one co-worker who would like to access the KVM host, from a Win7 system. EDIT #1 I'm familiar with running a X11 server on windows such as Xming, and remote displaying virt-manager from the KVM host to a windows workstation, but what I'd really like here is to know of any solutions native to windows, i.e. is there a version of virt-manager that'll run on windows.

• Installing a program on Linux: providing a short command

  - by rwallace

  Suppose you're distributing a program to run on Linux, call it Foo, and the program executable is called foo.exe (because it's a CLR program so it runs under Mono) and it needs a couple of DLLs in the same directory and maybe a later version might need some data files that it reads on startup and whatever, so relocating it to a global bin directory is a bit of hassle and it really prefers to remain in its original directory... But the user would prefer to invoke the program by typing foo instead of mono /path/to/foo.exe. What's the best/most usual way to provide such a short command? Can/should an install script/makefile create a one line script called foo that invokes the full path, and put the one line script in a global bin directory? If so, what should be the target bin directory, and are there any directions about exactly how to do this? Or is there a preferred alternative?

• how to log trigger intiated CRUD queries on postgresql 8.4

  - by user47650

  in the postgresql config file there is an option log_statement = 'mod' which causes CRUD statements to be logged. However this does not include the CRUD statements that are called from trigger functions, which means that following the log file is not useful to determine what changes are being made to the database data, if the 3rd part application has been making lots of changes using triggers. Is there some other option I can use to include trigger CRUD? alternatively, can I inspect the pg_xlog in real time using some tool? (xlogdump and xlogviewer do not work with version 8.4, i have tried)

• Apache + LDAP Auth: access to / failed, reason: require directives present and no Authoritative hand

  - by Karolis T.

  Can't solve this one, here's my .htaccess: AuthPAM_Enabled Off AuthType Basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthName "MESSAGE" Require ldap-group cn=CHANGED, cn=CHANGED AuthLDAPURL "ldap://localhost/dc=CHANGED,dc=CHANGED?uid?sub?(objectClass=posixAccount)" AuthLDAPBindDN CHANGED AuthLDAPBindPassword CHANGED AuthLDAPGroupAttribute memberUid AuthLDAPURL is correct, BindDN and BindPassword are correct also (verified with ldapvi -D ..). Apache version: Apache/2.2.9 (Debian) The error message seems cryptic to me, I have AuthzLDAPAuthoritative on so where's the problem. EDIT: LDAP modules are loaded, the problem is not with them being missing. # ls /etc/apache2/mods-enabled/*ldap* /etc/apache2/mods-enabled/authnz_ldap.load /etc/apache2/mods-enabled/ldap.load EDIT2: Solved it by changing funky Require ldap-group cn=CHANGED, cn=CHANGED line with Require valid-user Since AuthzLDAPAuthoritative is on, no other auth methods will be used and valid-user requirement will auth via LDAP. (right? :/)

• Video compression artifacts in Flash

  - by lvanderhart

  This only started happening in the past two days, which seems very odd to me. Everything worked flawlessly up until now, and I use my my computer as my primary TV. Flash video from Hulu and Amazon, for no apparent reason, now have lots of artifacts in them. Some scenes are ok, but some are completely scrambled and unwatchable. My connection is a 15mb fios, and bandwidth tests indicate my connection speed is ok. I've tried the latest production version of Flash, as well as the 10.1RC4. Same problem. Enabling or disabling hardware acceleration in Flash makes no difference (with the scrambling issue, quality is better overall with hardware). Using a different H264 codec doesn't clean up the issue, although the scrambling does look different. I'm kind of stumped. The only thing I can think of now is to reinstall windows, which is obviously a drastic step. Edit: Forgot to say: Windows 7, Athlon 64X2, Geforce GTS 250

• How do I make my Geforce GTS 250's power save mode stop causing audio stuttering?

  - by Matt

  Whenever my GTS 250 enters its power save mode, downscaling its frequencies, my audio stutters. This affects both my onboard audio and my Audigy Soundblaster 2 ZS. Changing Windows power save mode options such as PCI-E link state power management or Power Management Mode in the nVidia control panel have no effect on this issue. Replacing the power supply had no effect on this issue. The BIOS is the latest version, and I have the latest motherboard chipset and graphics drivers installed. I do not overclock. I started to see this issue after I upgraded my rig from its Socket 939 board to a Socket 1156 board with a Core i5-750 while simultaneously upgrading from Vista to 7.

• How do I reference the value of a constructed environment variable in a loop?

  - by Rob Spieldenner

  What I'm trying to do is loop over environment variables. I have a number of installs that change and each install has 3 IPs to push files to and run scripts on, and I want to automate this as much as possible (so that I only have to modify a file that I'll source with the environment variables). The following is a simplified version that once I figure out I can solve my problem. So given in my.props: COUNT=2 A_0=foo B_0=bar A_1=fizz B_1=buzz I want to fill in the for loop in the following script #!/bin/bash . <path>/my.props for ((i=0; i < COUNT; i++)) do <script here> done So that I can get the values from the environment variables. Like the following(but that actually work): echo $A_$i $B_$i or A=A_$i B=B_$i echo $A $B returns foo bar then fizz buzz

• Installing Linux kernel 2.6.25.14 on RHEL 5.4

  - by aaron

  I have to install Linux kernel version 2.5.25.14 on a RHEL 5.4 server because of drive compatibility issues. I follow the RedHat "Building a Custom Kernel" instructions running the following: $ make mrproper $ make xconfig $ make clean $ make bzImage $ make modules $ make modules_install $ make install But I get a bunch of warnings like this: WARNING: No module ehci-hcd found for kernel 2.6.25.24, continuing anyway When I try to boot this kernel it is unable to mount the hard drive, and kernel panics on startup. As far as I can tell I'm using a standard configuration (I just accept the defaults and save a .config file). Is there something I'm missing? Thanks.

• OpenWrt Backfire 10.03 Frequently Becoming Unresponsive (Bridged Client)

  - by Christopher Parker

  I have a Linksys WRT54G version 2 that I've flashed with OpenWrt Backfire 10.03. It's acting as a bridged client using the wl.o driver to give me network access in my home office, which is in a far corner of my house in a position that would make it exceedingly difficult to fish network cabling in through the walls. I have three network-ready devices attached to the device that don't currently support WiFi, including a networked printer. Ever since I migrated from WhiteRussian, which was also set up as a bridged client, to Backfire, the device has been becoming unresponsive, as though the OS itself has crashed or frozen. The WLAN light becomes completely solid and the LAN lights stay mostly solid, blipping off and then back on again maybe once a second or so. They all blink more or less in unison. Is there some way I can diagnose why this is happening so I can fix it? Right now, the only way to fix it is to unplug the device and plug it back in.

• Files turned into folders on external hard drive

  - by Kashif

  I have a networked hard drive where I like to store audio/video/software and all sorts of other files for my house. While the software files are all intact and working, many of my video and audio files have been turned into folders! Can anyone explain why this is happening, how I can prevent it, and if it is possible to revert these "folders" back into files. Thanks much! An example of what the folders are named: "Highschool Graduation.avi", "Birthday party.avi", "Somesong.mp3" The HDD is connected to a Linksys E4200 router (Firmware Version: 2.0.37). This is how the HDD is networked.

• Intel Rapid Storage Technology service always crashes

  - by Massimo

  I'm running Windows 7 x64 on a system based on an Asus Z87-Deluxe motherboard; the storage is configured for RAID mode; there is a single SSD drive for the O.S. and two 4-TB disks in a RAID 1 setup for the data. I've installed the latest version of Intel's Rapid Storage Technology drivers, 12.8.0.1016. The program complains about its service not being running, and the service is actually stopped; if I try to start it, it crashes. I've already tried reinstalling the package, but nothing changed. All the disks work correctly, but the RST program is unusable. How can I fix this?
