• Xorg fails to start under Ubuntu

  - by den-javamaniac

  I'm running desktop Ubuntu 9.10 on my Dell laptop. Previously it was Ubuntu 9.04. After some period of time (lets say 3-4 months) my X fails to start automatically after some restart calls. If that takes place my network manager applet doesn't start either (after I do startx). Can any one point out what I'm missing/what's the problem? EDDITED I get a perfect server boot meaning there's no Xorg started. Command line interface is all I get starting from login and further.

• How to backup data from linux servers to linux server (incremental + snapshot)?

  - by wag2639

  We have a handful of hosted servers running RHEL4 and RHEL5 and would like to backup some key folders (I'm thinking /var /srv and /etc) to a local server we have in house. The local server is running Ubuntu 9.10 Server edition. I'm looking for a free (preferably OSS) way to grab (or push) incremental backups to my local server and once a month or so, make a new snapshot for incremental updates in between snapshots. Also, while I'm comfortable with using a command line, others may need to use the system in the future, and I would like some kind of graphical or web interface to browse the backup repository. Suggestions?

• Is there a software like AutoCAD, but only 2D, not 3D?

  - by Saeed Neamati

  I love AutuCAD. It's powerful, easy to use, and fits engineering mind. It rocks when you want to draw 2D diagrams and shapes and one the cool features I like about it, is its snapping power. You draw a simple rectangle, then you can very easily create a circumscribe circle around it. However, new version of it are becoming really heavy (in size) and need high tech hardware, because of its powerful 3D capabilities, and rendering engines coming with it. I only want the 2D part of AutoCAD. Is there any software out there, which resembles AutoCAD (like having a console, where you can type L and get the line tool, or having snapping capability, etc.), but is small in size? In other words, what software can be named as AutoCAD 2D alternative?

• How do I remove 1,000,000 directories?

  - by harper

  I found that in a directory more than 1,000,000 subdirectories has been created due to a bug. I want to remove all these directories, let's say in the directory WebsiteCache. My first approach was to use the command line tool: cd WebsiteCache rmdir /Q /S . This will remove all subdirectories except the directory WebsiteCache itself, since it is the current working directory. I noticed after two hours that the directoriws starting with A-H have been removed. Why does rmdir removes the directories in alphabetical order? It must take additional effort to do this ordered. What is the fastest way to delete such an amount of directories?

• Prevent Excel Chart Data Labels overlapping

  - by Nicholas

  I have an Excel dashboard with line charts containing data labels. Specifically, we are only using the data labels at the rightmost end of the lines, and the labels consist of the Series name and final value. By changing a dropdown, the dashboard is automatically updated to give 19 different dashboards. The problem is that we can't work out any way of preventing the labels overlapping. Everything else on the dashboard can be made to automatically update nicely, except for this. Can anybody think of a way to do this? E.g. plugin or macro.

• IIS doesn't respond to 127.0.0.1 (external IP works fine)

  - by Jordan

  I have an AWS web server - call it box.company.com. It's running IIS and if I visit http://box.company.com in a web browser (from any machine, including box.company.com), it responds correctly with our site. However, if I visit localhost/ or 127.0.0.1/ when I'm logged into box.company.com, I get a "couldn't connect to host" message. The hosts file has only one entry - the standard "127.0.0.1 localhost" line. Pinging 127.0.0.1 works fine. Pinging localhost correctly resolves to 127.0.0.1 and works fine. I've tried restarting IIS and restarting the DNS Cache. I had this problem once before, and restarting the server fixed it, but I'd like to know what's going on in case this happens again in the future.

• How do I debug an upstart job?

  - by Cerales

  I have the following job in /etc/init/collector: start on runlevel [2345] stop on runlevel [!2345] expect daemon exec /usr/bin/twistd -y /path/to/my/tac/file When I start the job with sudo service collector start, it hangs. If I ctrl-c and run initctl list, I see this: collector start/killed, process 616 I can't see an instance of the twistd daemon in ps, and the HTTP server it's supposed to be providing does not exist. I even tried this without 'expect daemon' and with a simple call to a one-line bash script using a script stanza, and it still doesn't work. I think I'm doing something very wrong. What could it be?

• Server 2012 file server security - File access through software only?

  - by user1607914

  I have just setup a server 2012 essentials R2 box as a test bed for my small business. Its running Essentials R2 as a VM on a Essentials R2 host. I have set it up to be the DC and DHCP server and joined a client. My next task is to use it as a file server but I am not quite sure how to set it up. All the client interactions with the file server will be through client side software. I therefore do not want any access to the files apart from through the software. I have looked at the ntfs permissions and there is a permission called "List Folder/Read Data" however I am unsure this will do what I want. Is it possible to give access to the files but not allow access through the windows explorer / command line?

• Firewall blocks outgoing email

  - by Martin Trigaux

  On my Debian server running a Django website, I have an error when I need to send an email. The error received is Exception Type: gaierror Exception Value: [Errno -2] Name or service not known Exception Location: /usr/lib/python2.6/socket.py in create_connection, line 547 You can see the full error log here. After testing, it seems it is my firewall that blocks the request. You can see my iptable file (/etc/init.d/firewall). I think the problem comes from the two commented lines that were supposed to accepts all established connections. When I uncomment them, I have an error iptables: No chain/target/match by that name. Thank you

• Debian doesn't boot after removing secondary hard drive

  - by Daveel

  In the beginning I had Debian 6 running on one hard drive (/dev/sda1). Then I decided to keep all my stuff(pics, videos, etc..) in another slave hard drive (/dev/sdb1). So sda1 has Debian OS sdb1 doesn't contain any OS files I have made it to mount automatically by adding a row in /etc/fstab (UUID and directory to mount to) Time have passed and when I tried to change that secondary hard drive with another hard drive with bigger capacity, for some reason Debian won't boot (just itself sda1) after removing secondary hard drive (sdb1) But if I plug sdb1 back, it boots just fine. I tried to comment line out from /etc/fstab, so it doesn't mount And also did update-grub after umount /dev/sdb1 What's the right way to remove hard drive secondary hard drive?

• Bootstrapped Ubuntu 12.04 EC2 instance. Where to find log?

  - by nocode

  So I bootstrapped a shell script to install and run a bunch of tasks. Looks like the it ran for the most part, but I added one part and that was formatting an extra EBS volume. Pretty straightforward: mkfs.ext4 /dev/xvdf mkdir –m 000 /vol01 echo “/dev/xvdf /vol01 auto noatime 0 0” | sudo tee –a /etc/fstab sudo mount /vol01 I was able to install MongoDB, NGINX and Forever. I selected to use /dev/xdvf in the AWS console and see it. The 3rd line is not in fstab either. I've searched through various logs in /var/log/ but I don't really see much indicating the execution of the bootstrap. Logs that I see and looked through: auth.log boot.log dmesg dpkg.log syslog udev

• Xmodmap: six characters to one key and two layouts?

  - by sup

  I know how to have six symbols on one key thanks to this question: Xmodmap: Six characters to one key? However, when I have two layouts and switch them, weird things happen. I have the following (well, different, but this is easier to talk about) line in my xmodmap: keycode 31 = a A b B c C When I log in, everything works as you would expect. Pressing key 31 give a, with Shift A, with AltGr c and C respectively and with ISO_Level3_Shift. However, when I change the layout, key 31 gives me b and B with shift and c and C with AltGr. This is on Ubuntu 11.10 under Ubuntu. Does anybody undestand what is happening? Could I restrict xmodmap to just one layout?

• Fixing fill-paragraph with comments in Emacs 23.2.1

  - by Silfheed

  I just upgraded to emacs 23.2.1 when I finally upgraded to ubuntu 10.10, but the first thing I noticed is that fill-paragraph (M-q) doesnt work nicely with comments anymore or at least do not work the way they did in emacs 23.1.? that I had before the upgrade. The main issue is that if I have a commented line such as //This is a long comment to illustrate an issue I have with emacs lorem ipsum and then do fill-paragraph (M-q) afterwards, I get //This is a long comment to illustrate an issue I have with emacs lorem ipsum whereas I should get //This is a long comment to illustrate an issue I have with //emacs lorem ipsum I've killed my .emacs file to try and narrow down where the issue is popping up, but this still pops up even in vanilla emacs.

• Hyperlinks on images in PDF from Word 2010

  - by Bristol

  I've got a Word 2010 document that I'm trying to convert to a PDF with "Save As...", preserving hyperlinks. Something odd is going on: Hyperlinks on inline text, or images that are inline, work fine. Hyperlinks on images with layout "in front of" text don't work in the PDF, same for hyperlinked drawing shapes. What I'm trying to do is make a "clickmap" image by putting an image on the page and overlaying parts of it with transparent shapes that hyperlink to different URLs. This isn't working, and the transparency has nothing to do with it - hyperlinks in the PDF seem only to work on "in line with text" elements. Am I missing something, or is there a better way to do this?

• Hyper-V: determine the guest's name given the GUID

  - by syneticon-dj

  How would I go about determining the guest's name given its GUID or vice-versa, preferably with only the Hyper-V/Server Core stock install at hands? Rationale: I am in favor of having a repository of dirty tricks to revert to when in great need. To immediately quiesce all (storage) operations of a VM guest without losing the state, I used to run kill 17 <all VM's virtual processes> (signaling SIGSTOP) and resumed afterwards using kill 19 <all VM's virtual processes> (signaling SIGCONT) in ESXi/vSphere shell. I tried the same technique with Hyper-V using Process Explorer's "Suspend" functionality on the vmwp.exe processes and it seemed to work. I have yet to find a way for easily identifying the processes to suspend, though - the vmwp command line is only listing a GUID.

• Mac | Router not assigning the IP address.

  - by Vaibhav Bajpai

  I recently installed Mac OS X 10.6, however the ethernet state is down. The assigned IP is 169.x.x.x. When booted the live USB of Ubuntu, I properly get an IP assigned in the range 192.168.1.x from the router 192.168.1.1 I am using the same router and same ethernet line. I tried to ping to 192.168.1.1 from my Mac and I get a host down message. I tried to manually assign the IP and set the router IP to 192.168.1.1 but still the router is unreachable.

• Unable to mount cifs in redhat 6

  I am relatively new to Linux, and I am trying to mount a CIFS filesystem from an openfiler instance I have on my network in Red Hat. The openfiler instance is authenticating using AD.

• Redirecting output to email

  - by Alpha

  I am aware that in Windows you can use the following snippet to redirect the output of a command line tool to the clipboard: mytool | clip Also, it can be done with files: clip < myFile.txt I also know Windows has several other devices you can use as output / input for these redirections (probably the printer is the most famous of them). However, is there something to send the text to the default email program? I would love to find that there is something like: mytool | email. Is there something alike?

• File type actions for ruby scripts

  - by Kovags

  Hello, I just installed the Ruby interpreter and created the file test.rb. In the Folder Options, I created the rb file type and an action called Run and assigned the application C:\Ruby192\bin\ruby.exe "%1"" So It's possible for to get into the Windows XP command line and run the script simply by doing this: C:\>test.rb But when I need to send parameters to the script, I can't simply do the following: C:test.rb parameter1 parameter2 I'll have to do the following instead: C:\Ruby192\bin\ruby.exe c:\test.rb parameter1 parameter2 I just noticed that I'm able to edit the action the following way to pass more parameters: C:\Ruby192\bin\ruby.exe "%1" "%2" "%3"" That allows me to give 2 parameters to the script, but for some cases I need to pass a handful of parameters and it doesn't seem right for me to append "%5" "%6" "%7" ad nauseam. What's the canonical way to do it?

• Can I compile mutt under cygwin?

  - by openist

  I've been trying to compile mutt under cygwin for a few days. The included version is outdated and does not include things I need like header caching. Anyways, I always get the message: "configure: error: no curses library found" I have all the curses + devel stuff installed + termpcap, which I heard might be related. I've tried re-installing, i've tried specifying the location on the configure command line, but i'm not sure i'm doing it right: "--with-curses=/usr/lib/libncurses.a --with-curses=/usr/lib/libncurses.dll.a --with-curses=/usr/include/ncurses" Here's my config.log: http://floatsolutions.net/docs/config.log Any ideas?

• How to rotate attached monitor to notebook of Sony's Z-series?

  - by user67175

  Is it possible that Sony is selling a top of the line, hugely expensive computer that does not have the basic ability to rotate an attached monitor? Is it possible that the Z-series simply can't do this? The Windows control panel is missing the normal option for "rotation", as is the Nvidia control panel for "orientation" , no additional rotation software works. Sony sales says they do not know the answer to this. Sony technical supports says that the problem lies with Nvidia, Nvidia technical supports says the problem lies with Sony. Any advice for a fix for this short of returning the computer would be greatly appreciated. Also wondering if this problem is common to computers running Windows 7?

• Cronjob terminates early

  - by TheBigO

  In my crontab file I execute a script like so (I edit the crontab using sudo crontab -e): 01 * * * * bash /etc/m/start.sh The script runs some other scripts like so: sudo bash -c "/etc/m/abc.sh --option=1" & sleep 2 sudo bash -c "/etc/m/abc.sh --option=2" & When cron runs the script start.sh, I do ps aux | grep abc.sh and I see the abc.sh script running. After a couple of seconds, the script is no longer running, even though abc.sh should take hours to finish. If I do sudo bash /etc/m/start.sh & from the command line, everything works fine (the abc.sh scripts run for hours in the background until they complete). How do I debug this? Is there something I'm doing that is preventing these scripts from running in the background until they are done?
