• Monitor Processes' Memory Usage

  - by Alvin Sim

  We have an IBM P series box running AIX 5.3. This is our application server, whereby our J2EE application is running in Oracle's Applications Server (version 10g r2). At around 11pm till the next day 7am, we have shell scripts running, which executes Java class programs. Recently, this server has been experiencing some high memory usage, which caused some of the Java class programs throwing "Out of memory" exception . We normally use NMON to monitor the server's resources, such as CPU, I/O, memory, etc. But because of this OOM issue, we would like to know throughout the day, what are the processes which are running and how much memory each process consumed. NMON is not able to show this. Even with the "-T" parameter, it only shows the top processes and not all. Is there any thing we can use to monitor all the processes' memory?

• who has the best online prep MCSE study materials?

  - by phill

  I'm studying for my Microsoft Certified Systems Engineer (MCSE) on my own and was wondering who you could recommend for study materials? I did shell out a bunch of money for a local class and when it came to taking the test, there were a slew of topics which weren't even covered. For example, in my 070-293 test, they didn't even touch such as Certificates, how to setup clusters, sql server clustering, etcs. I realize there is a bunch out there such as cbtnuggets, preplogic, etcs. Which online preps do you suggest best preps you for the tests before I spend any more money on this stuff? thanks in advance

• How to get rid of diacritics on my keyboard?

  - by stevenvh

  I searched Google and SU for my problem, but everybody seems to want to add diacritics, while I don't want them. I'm using Windows 7 and have a US keyboard installed, not the international version. Despite that some keys, like ", ^ and ~ are used for diacritics, which means that I have to type "SPACE to get a double quote. How do I get rid of this? My other PC, with the same settings, doesn't show this behavior. edit re Stefan's answer I don't see the icon Stefan refers to in my taskbar, probably because I have Classic Shell installed. But this is a screenshot of the Input Languages dialog, there are no other keyboards installed:

• Showing protocol specific mini icons for Jabber/XMPP gateway contacts

  - by aef

  Since a short while I'm using Ubuntu Oneiric Ocelot (11.10) with gnome-shell (Gnome 3) and I'm trying to get accustomed to the default Empathy Instant Messaging client. I'm using a gateway service on the side of my Jabber/XMPP server to communicate with lots of contacts over proprietary networks like ICQ or MSN. So I don't use Empathy's native support for ICQ and MSN, and I don't want to change back to using such a thing for various reasons. One thing that annoys me is that Empathy does not make it clear to me that these contacts are from another instant messaging network. If I enable the View Show Protocols option they are all recognized as Jabber/XMPP contacts. Although I perfectly understand why that happens, I would like to be able to change this behavior to make Empathy mark these contacts correctly. Is there a configuration option or a plugin for this? Or may this feature still be in development and will be available later?

• Recover data from a corrupted virtualbox vmdk file?

  - by Neth

  The power went out while I was doing a build on a VirtualBox machine, when I restarted the vmdk for the disk the vm was using was corrupted, apparently irrecoverably. I have been able to grep the 66GB vmdk file and it finds strings from the code I was working on that hadn't gotten in to subversion yet (yeah, yeah I know). But the strings are either in the shell history or what look to be strings inside object files. Any ideas for finding/recovering the source code? If it helps the vm was Linux, Fedora Core 10 on an ext3 filesystem. The host is an ubuntu 10.04_amd64 and has an ext4 filesystem.

• Linux file permissions not being preserved

  - by yellavon

  I am deploying some custom software as root (a necessity for this situation). I set the owner/group to user1:user1 and set all the files to 644 beforehand in shell, then copy and deploy with ant. However, when files get copied over from the deployment directory, the ownership changes back to root and all the files install with 666 permissions. This seems to occur whether the file is overwritten or newly created. I believe there is a way to set an option in cp, mv commands to preserve permissions, but that would be a lot of commands to change. How can I fix this? Is there some setting I can change temporarily for root so the install always preserves the file permissions?

• How to repair unbootable Fedora install

  - by Cerin

  How do you repair/reinstall Fedora without deleting any existing partitions or data? I was attempting to upgrade some old Fedora 13 servers to 17, following the instructions in the wiki. After the 14-15 upgrade, rebooting resulted in the output: Dropping to debug shell. sh: can't access tty; job control turned off dracut:/# Running dmesg also shows: dracut Warning: No root device "block:/dev/mapper/VolGroup-lv_root" found Googling shows this error is typically related to some weird RAID issues, but my server is a virtual machine not using any RAID. Using a rescue CD, I can chroot /mnt/sysimage, and all packages and data still seems to be there. How do I make the system bootable again?

• How to troubleshoot a remote wmi query/access failure?

  - by Roman

  I'm using Powershell to query a remote computer in a domain for a wmi object, eg: "gwmi -computer test -class win32_bios". I get this error message: Value does not fall within the expected range Executing the query local under the same user works fine. It seems to happen on both windows 2003 and also 2008 systems. The user that runs the shell has admin rights on the local and remote server. I checked wmi and dcom permissions as far as I know how to do this, they seem to be the same on a server where it works, and another where it does not. I think it is not a network issue, all ports are open that are needed, and it also happens within the same subnet. When sniffing the traffic we see the following errors: RPC: c/o Alter Cont Resp: Call=0x2 Assoc Grp=0x4E4E Xmit=0x16D0 Recv=0x16D0 Warning: GssAPIMechanism is not found, either caused by not reassembled, conversation off or filtering. And an errormessage from Kerberos: Kerberos: KRB_ERROR - KDC_ERR_BADOPTION (13) The option code in the packet is 0x40830000 Any idea what I should look into?

• Can I make ssh tell me which control file it would use for multiplexing?

  - by Ryan Thompson

  I am using the following options in my ~/.ssh/config in order to enable connection multiplexing: ControlMaster auto ControlPath ~/.ssh/control/master-%r@%h:%p However, this has the annoying problem that the first shell to connect to a particular server must be the last to disconnect, because it is the master connection that all the other connections are using. So if you log out of the master, it appears to just hang. To solve this, I would like to wrap ssh with a script that checks if the control master file exists, and if not, starts a master ssh process in the background. Then it would start a slave ssh session. In order to accomplish this, my script would have to determine the path to the control file that ssh would use. This would entail parsing the ssh command line options and config files and implementing the logic for determining the ControlPath. Is there any way to just ask ssh what path it would use, so I can check it?

• SQL Server Management Studio Connect to Server List Editing

  - by Paul Farry

  I'm using SQLServer Management Studio (2005) and I have a fairly lengthy list of servers in there, and I'd like to get rid of some of them that are no longer in use, without having to set them all up again. I know that the C:\Users\*\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat can be deleted and this will remove ALL the entries, but is there anyway to just delete some of them? (Coding info) I looked at the file and it is a serialised blob from the Microsoft.SqlServer.Express.ConnectionDlg.dll (Class Personalization) in the Appplication directory, but all the methods are private. So I can't just create an instance of this and then call Remove on the entries. Update I have written an Article on CodeProject explaining How this can be achieved. http://www.codeproject.com/KB/vb/AlterSQL2005MRU.aspx

• modify the way files get opened from finder by shift-clicking (etc) as in windows

  - by stib

  In the windows shell it is possible to modify the default action for opening any document type when holding down a modifier key such as shift or option when double clicking. So for example I can open a jpeg in irfanview if I just double click it, in firefox if I shift-double click it or in potatoshop if I option-double click it. However on a mac I have to right click, and choose "open with..", which can be annoying when there are a lot of possible candidates (such as with jpegs) or if I want to open the file with somehting like an applescript, which won't show up on the list and will have to be found in the file system and specified manually, every.. single.. time. Is there a way of making the mac open files differently by holding down modifier keys when double clicking?

• Recommended way to restrict Apache users

  - by Dor

  Following on why should we restrict Apache users, another two questions arises: What is the recommended method of restricting the places Apache users can traverse & read in the file system? What to do against fork bombs and other shell scripting problems? (bash scripting is allowed) My possible solutions (I prefer to know which solution you choose and why): chroot OR mod_chroot disable bash OR use Restricted BASH Please offer another solutions if you find appropriate. (perhaps selinux is?) Current status: Users are allowed to executed bash scripts (via PHP for example) suexec is active Apache requested are served with FastCGI for PHP

• sudo prompts for password over ssh

  - by Joe Watkins

  I have sudo set up for a shell script as follows on "hostname" (sudo -l output): (suser) NOPASSWD: /path/script* sudoers content is: myuser ALL=(suser) NOPASSWD: /path/script* this works fine, so I can run the following, logged in locally on hostname, without need for password: sudo -u suser /path/script however, when I use ssh (with keys set up, so no password require) to login and run, as follows: ssh hostname sudo -u suser /path/script I get prompted for a password, and when the password is entered I get: Sorry, user myuser is not allowed to execute '/path/script' as suser on hostname. Why? NB the following does not prompt for password at any point: $ ssh hostname $ sudo -u suser /path/script

• Systemd can't start script?

  - by TokyoMEWS

  I have a BASH-script I want to run on start up. My system is running systemd so I created a .service file with whith what I think is the neccessary information: [Unit] Description=My Script After=network.target [Service] ExecStart=/home/myscript.sh [Install] WantedBy=multi-user.target I used systemctl enable to 'register' it an rebooted. On boot I was told my script would be executed, but I could neither see any of the messages ECHO should display on screen nor did it write something to a file, according to what I had written in the script. Additionally, It does not start the application it's supposed to start. Systemctl status tells me that the script has run and exited successfully. Still, the script has no effect. If I run the script from a shell it works perfectly fine. Do any of you know what could be my problem?

• Kubuntu Monitor Out of Range

  - by uncleo

  My X server seems to be faulty, but I don't know why. I had some problems last week with a new motherboard, but they seemed to be resolved. Today, I updated Kubuntu and restarted, but my Viewsonic VX900 LCD monitor shows the splash screen for several seconds, then displays the message "Out of Range" I have tried various kernels in Grub, some in recovery mode, most do the same thing. No key combinations bring up a shell prompt like I expect. The one exception was a very old kernel, that would only mount the file system as read-only, so I can't fix up the xorg.conf file. Is there anything to be done?

• cannot run CMD script from Vista windows explorer

  - by jamesvista

  I am running Vista Home Premium. I tried to write a script to do some simple automation.... it does not work! even the most simple script like: @echo ON dir . does not get executed and only an empty CMD shell pops open when started from explorer. From the cmd windows there is no problem. This is really weird and I have never seen this before (but wrote many CMD scripts before) ftype cmdfile and batfile are unchanged from "%1" %* virusscan done - no problems Is there a policy setting that might have changed? Any ideas?

• Modifying the initrd.img to run additional binaries in a PXE booted RHEL 6

  - by Charles Long

  I am trying to add additional automation to our existing RHEL 6 (or Oralce's implementation thereof) PXE install process by running a script in the %pre section of my kickstart config that call hpacucli, HP's raid device configuration binary. My approach has been to modify the PXE served initrd.img. I've unpacked the initrd.img and copied in the required libraries, binaries, and scripts but when the system boots using the modified initrd.img, the modified /lib (and /lib_64) are moved aside to /lib_old and /lib is linked to the /mnt/runtime/lib. How can I change this configuration so that the /lib is not moved (unlikely) or required libraries are available in the runtime /mnt/runtime/lib? To test and confirm this I've been able to get the install process to move to the 6th virtual console, which allows me to see errors, and then open a shell (a useful debugging mechanism). %pre exec /dev/tty6 2 /dev/tty6 chvt 6 /bin/sh

• How to pass AppleScripts display dialog to Growl or growlnotify?

  - by pattulus

  I have this simple AppleScript which takes the text in the clipboard and outputs the amount of words and characters used. What I'm trying to do is passing "display dialog" to Growl or growlnotify. I know how to use growlnotify in the shell - it's great and highly customizable (stick note, assign app icon or an image, etc) - but the point is: I don't know how to do it in AppleScript. I google a bit but now time has passed and I decided to post my question here. So, here's the script: set myCount to count (the clipboard) set myWords to count words of (the clipboard) set myParas to count paragraphs of (the clipboard) display dialog "Characters: " & myCount & " Words: " & myWords & " Paragraphs: " & myParas Thanks.

• Count the Number of Characters in a Full FIle Path?

  - by Richie086

  I need to be able to count the number of characters in a full path to a file in windows. How I am currently accomplishing this task is as follows: Open a command prompt cd to the directory in question (for example c:\CruiseControl\ProjectArtifacts\ProjectName) type the following command dir /s /b output.csv Open the resulting output.csv file in excel. use the =LEN() function in excel to count the number of characters per row as listed in the output.csv file. Does anyone know of an explorer shell extension, or some 3rd party tool that could preform this function without me having to manipulate the output from dir in excel? Is there some easier way to go about doing this? The root of the issue I am having is the ~260 character file path limit in Windows. I am trying to analyze which paths are approx ~260 characters so I can shorten them to avoid getting this error.

• windows 2003 - why can't serial port be accessed remotely?

  - by Danny Staple

  we have recently installed the updates on some of our servers, which have a bit of hardware attached via USB that presents itself as a serial (COM) port. The strange behaviour is that if I start a cmd shell on the server via VNC, I can open the serial port. If I run a service and start it from there (telnet, jenkins) then I receive a "not found" error for it. IE: C:\Documents and Settings\some_user>echo 1 >COM4: C:\Documents and Settings\some_user> on the local cmd will work, and on the remote telnet will give: C:\Documents and Settings\some_user>echo 1 >COM4: The system cannot find the file specified. C:\Documents and Settings\some_user> I cannot see any security settings on the Device manager settings panel for this device.

• Where do you find the Bash source files of programs in Linux/Mac OSX?

  - by AndrewKS

  I am currently writing some convenience methods for my terminal in my bash_profile and am sure if what I am writing is "the best way". I figure a good way to verify whether what I'm doing is right or not would be to find some source code of more established programs and see how they do it. My question then is, where can I find this code on my Mac? An example is, with Macports installed, where is the source code that opens the port interactive console when I type nothing but "port" in my shell? (I added Linux in the title even though I am on a Mac because I assume the answer would be the same for both) Edit: The answer I am looking for is in terms of which directory relative to the programs will I find their unix scripts.

• How do I reattach to Ubuntu Server's 'do-release-upgrade' process?

  - by Alex Leach

  I accidentally pressed Ctrl+C during Ubuntu Server's do-release-upgrade process. I'd dropped to a shell to compare a .conf file in /etc/. When I pressed Ctrl-C, it asked whether I wanted to try to reattach to the upgrade process, but it failed to do so. So I quit, and now there's a hanging dpkg process which is holding onto the apt lock. This is a virtualised server with no GUI frontend... Is it possible to recover the upgrade process, or do I have to kill the dpkg process and start again? UPDATE:- AFAICT, there was no way to reattach to the upgrade process. However, it wasn't a disaster at all. I killed the hanging dpkg process, and then ran dpkg --configure -a. This walks you through reconfiguring all packages already installed on the system, tidying up any problems whilst it does so. After that, I used aptitude to upgrade the remaining packages, which had already been downloaded, but hadn't been installed or configured.
