• How to call a program and exit from the shell (the caller) when program is active?

  - by Jack

  I want to run a program with GUI, by typing into konsole: foo args … and exit from the shell (that's the caller) when the program (foo) is active. How do I this? Is there a Linux/Unix built-in command/program to do it? I'm not a shell-man, really. I know that it's possible by writing a small program in C or C++ (any other programming language with small I/O interface on POSIX) programming language with the fork() and one-of exec*() function family. It may take some time; I'll do it only if there is no native solution. Sorry for my bad English; it's not my native language. Also, not sure on tags, please edit for me, if I'm wrong. If it matters, I'm using OpenSUSE 10.x.

• Quickbooks and Cisco ASA 5505

  - by user41516

  I have a Cisco ASA 5505, and everything has seemed to function fine, however I have had problems with Quickbooks 2008 running super slow over the network (Samba) and narrowed it down to the Cisco box. Other Samba transfers seem to be pretty fast, and the Quickbooks file is not very large at all (<25 MB), and other Samba transfers seem to be fine. However, I'm not sure if Quickbooks uses another protocol or if there are other ports that need to be opened. Can anybody give me any clues on how to resolve or troubleshoot the problem or have any prior experience with running Quickbooks over a network?

• Apache: tmp is not writable

  - by Patrick

  hi, I've installed Drupal on a new webserver and I get the following errors: warning: is_writable() [function.is-writable]: open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/customers/rollergirl.ch/rollergirl.ch:/var/www/diagnostics:/usr/share/php) in /customers/rollergirl.ch/rollergirl.ch/httpd.www/drupal/sites/all/modules/imagecache/imagecache.install on line 37. ImageCache Temp Directory /tmp is not writeable by the webserver. I guess this happen because the server is not configured with a writable tmp folder I don't have access to Apache configuration file (I only know for sure it is Apache). Could you suggest me what to do ? I can only contact web server service ? thanks

• Managing service passwords with Puppet

  - by Jeff Ferland

  I'm setting up my Bacula configuration in Puppet. One thing I want to do is ensure that each password field is different. My current thought is to hash the hostname with a secret value that would ensure each file daemon has a unique password and that password can be written to both the director configuration and the file server. I definitely don't want to use one universal password as that would permit anybody who might compromise one machine to get access to any machine through Bacula. Is there another way to do this other than using a hash function to generate the passwords? Clarification: This is NOT about user accounts for services. This is about the authentication tokens (to use another term) in the client / server files. Example snippet: Director { # define myself Name = <%= hostname $>-dir QueryFile = "/etc/bacula/scripts/query.sql" WorkingDirectory = "/var/lib/bacula" PidDirectory = "/var/run/bacula" Maximum Concurrent Jobs = 3 Password = "<%= somePasswordFunction =>" # Console password Messages = Daemon }

• Scrolling mouse sets windows sound volume

  - by Ikke

  Suddenly, when I use the scroll wheel of my mouse, it changes the windows sound volume level. I have a HP DV6-2030SD laptop with Windows 7 64 bit and a Zolid p50622 mouse. When I use the scroll function of the mouse pad of the laptop, it does not adjust the sound level. I don't have any special mouse drivers installed, just the standard windows drivers. When I scroll, I see the HP sound level screen: It doesn't do it always, but when it does, it prevents the current window to scroll, which is really annoying. Rebooting doesn't help. I've tried to put the USB dongle in a different port, but this doesn't help either. Any advise on how I can fix this?

• XAMPP MySQL stops running after ~1.5 seconds

  - by Nona Urbiz

  I have tried installing it as a service. Nothing seems to work! I have checked the status page and MySQL is listed as "Deactivated". When trying to open phpMyAdmin I get: Error MySQL said: Documentation #1045 - Access denied for user 'root'@'localhost' (using password: NO) Connection for controluser as defined in your configuration failed. phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server. and from the CD demo: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: NO) in C:\xampp\htdocs\xampp\cds.php on line 77 Could not connect to database! Is MySQL running or did you change the password?        Thanks for any suggestions or help you can give!

• How to ignore moved lines in a diff

  - by klickverbot

  I am currently working on a source code generation tool. To make sure that my changes do no introduce any new bugs, a diff between the output of the program before and after my changes would theoretically be a valuable tool. However, this turns out to be harder than one might think, because the tool outputs lines where the order does not matter (like import statements, function declarations, …) in a semi-randomly ordered way. Because of this, the output of diff is cluttered with many changes that are in fact only lines moved to another position in the same file. Is there a way to make diff ignore these moves and only output the lines that have really been added or removed?

• Preventing logrotate's dateext from overwriting files

  - by Thirler

  I'm working with a system where I would like to use the dateext function of logrotate (or some other way) to add the date to a logfile when it is rotated. However in this system it is important that no logging is missing and dateext will overwrite any existing files (which will happen if logrotate is called twice on a day). Is there a reliable way to prevent dateext to overwrite existing files, but instead make another file?. It is acceptable that either no rotate happens or a file is created with a less predictable name (date with an extra number, or the time or something).

• Windows XP, USB-Stick and multiple Partitions

  - by Bobby

  Hello. I've got an USB-Stick with multiple Partitions on it (FAT32 (active), FAT32, Ext2 <-- that's another story) and it seems like that my Windows XP can only mount the first partition of the stick. If I try to mount the second one using the volume manager it tells me that I need to make it active and reboot...is it really that limited or am I just missing something here? Partitions: FAT32, System Rescue CD, bootable and active FAT32, some tools ext2, some data (I know that I need extra drivers etc., but that's not asked here. Edit (Solution): Thanks to the answer with the RMB (ReMoveable Bit) I was able to dig up a solution described at this site (Section: On flash drive only the first partition works). Basically, there's an Hitachi Driver available which filters the RMB on Driver-Level, which just needs to be a little modified to function with basically every USB-Stick. All you need to do is adding the "Device Instance ID" to the driver and then use this driver.

• bluetooth doesn't recognize mouse (and other devices)... sometimes

  - by Angelo

  I have a problem with bluetooth with Vista, running on my MacBook. It often doesn't recognize my wireless Magic Mouse. And I saw that it even doesn't seem to start as the pictogram in the task-bar isn't there most of the time I run Vista. But I'm only an Apple-nerd, so I don't know to much about this issue on Vista. When reinstalling Boothcamp or other updates, then once in a while bluetooth recognizes my own mouse (and other devices from some neighbours... so that implicates that the problem must be the bluetooth function in the first place, not my mouse.) Is there some update for the bluetooth application? Angelo

• How To: Transfer Categories in Outlook 2007 from One Installation to Another Using Google Sync

  - by nicorellius

  I use Outlook 2007 for email. I also happen to use the categories for organizing my mail. This function is cool, because you can use keyboard shortcuts that make categorizing mail quick and easy. The problem I am having is that, since I use Google Apps Sync at home and at work, I can't seem to figure out how to transfer the existing category assignments that I spent months creating at work. As my email comes and goes, I assign this and that, with thousands of messages all belonging to specific categories. When I finally installed and started using Google Apps Sync at home, the synchronization process works great, but all my messages are blank, i.e., don't have the color categories I assigned at work. What's worse, I actually changed computers at work, and now am facing the same problem on the new workstation. Using: Windows XP Pro, Outlook 2007, Google Apps. Anyone run into this and find a solution?

• Weird Windows 2003 MSDTC and SQL 2005 issue

  - by seagull surfer

  scenario: Windows 2003 sp2 x64 enterprise edition. SQL 2005 sp2 cu9 x64 Enterprise edition After restarting the resource groups on two node active-active cluster, 3 SQL 2005 instances start up fine. The 4th one starts up but starts throwing the following error. "Enlist operation failed: 0x8004d00e(XACT E NOTRANSACTION). SQL Server could not register with Microsoft Distributed Transaction Coordinator (MS DTC) as a resource manager for this transaction. The transaction may have been stopped by the client or the resource manager." MSDTC is fine since the other 3 function normally. The only way to "fix" it is to take the 4th instance offline and bring it online again. Is there any way to fix this enlistment without restarting?

• Kill .so file process

  - by demonofnight

  I have a program, I cannot change the code. It calls some .so file's function, but don't delete the object in the end. When the owner of the program tries to update the program he kills it and send the update, but the .so file is in use so he can't update the file. It's on an AIX platform. Is it possible to force to kill the .so file? If I do a fuser -f on the file it returns nothing. Can I create another program to kill the program, is there any command to do that?

• Printing on Windows 8 64-Bit through Windows Server 2008 (32 Bit) RemoteApp

  - by Chris

  We have a network where our server is running on Windows Server 2008 (32 Bit) and a client computer is running on Windows 8.1 (64 bit) with a local printer attached to the client. The printer is an HP P1006. The remote app works well but when trying to print we get an odd "error 545". We have tried both using the "connect client printer" function in remoteapp and also making the printer shared over the network and printing to it via the network from within the remoteapp. Nothing works. We can print a test page from the server to the client computer just fine, but it seems from remoteapp we cannot. We have also tried installing the 32 bit drivers on the 64 bit machine as both the primary and secondary drivers but cannot get them to install. Suggestions please? We've been going crazy over this issue.

• Is it possible to install and use a printer in Azure Worker Roles?

  - by lurkerbelow

  I'd like to know if it's possible to create and use a printer in Azure Worker Roles. I do know that I can install printers with basic batch commands. So I could define a batch script that would run as a startup task. something like: rundll32 printui.dll,PrintUIEntry /if /b "printer" /f %windir%\inf\ntprint.inf /r "file:" /m "printername") Question: Can I use a printer to print to file, maybe to local storage? I do need the function to print to file or atleast to have a printer installed, because I have to get the PCL output from different installed printers. Sadly I can not test it by myself. I do not have a CC to join the 90 days trial.

• SQL Server store procedure encrypt is safe?

  - by George2

  I am using SQL Server 2008 Enterprise on Windows Server 2003 Enterprise. I developed some store procedure for SQL Server and the machine installed with SQL Server may not be fully under my control (may be used by un-trusted 3rd party). I want to protect my store procedure T-SQL source code (i.e. not viewable by some other party) by using encrypt store procedure function provided by SQL Server. I am not sure whether encrypt store procedure is 100% safe and whether the administrator of the machine (installed with SQL Server) still have ways to view store procedure's source codes? thanks in advance, George

• postfix: force server to send mail outside of localhost

  - by LoneWolfPR

  I have a php file that sends mail using the mail() function. The problem is one of the forms sends to a domain that is registerred on my server while having the mail handled on a different server. Postfix looks locally only. When it doesn't find the email address is rejects the message. How can I configure postfix to send mail to all domains through the internet and not locally? Update Ok. So it wasn't a postfix issue at all. I simply needed to turn off mail to that domain from the command line. For anyone that needs that command it is (at least on my system): /usr/local/psa/bin/domain --update example.com -mail_service false

• add script on boot linux machine

  - by user1546679

  I have one script to start a service on my ubuntu. I added it on boot machine using "# update-rc.d projeto defaults". But it still doesn't start with the boot machine. I think is because I am using other user to start the script "su - www-data -c ...". But I am not sure, because I run the update-rc.d command as root. When I execute the script from a terminal, it asks the password of the user www-data. Does anyone know what is happening? Thanks a lot! Felipe #!/bin/bash # /var/www/boinc/projeto/bin/start function action { su - www-data -c "/var/www/boinc/projeto/bin/$1" } case $1 in start|stop|status) action $1 ;; *) echo "ERRO: usar $0 (start|stop|status)" exit 1 ;; esac

• Disable passwd history feature with remember=0

  - by user1915177

  PAM version - pam-0.79 Is setting 0 allowed on "remember" option in /etc/pam.d/common-passwd file of pam.d module to disable passwd history feature? With "remember=0" in /etc/pam.d/common-passwd file, I am observing a memfault when running the passwd command as a USER. When browsed the source, the function in _set_ctrl in support.c file of pam_unix module handles wrong values of remember, but currently its not robust enough to handle 0, which is a wrong value. So the valid and only option to disable history feature, is to not include the "remember" option in /etc/pam.d/common-passwd file and not to set-up /etc/security/opasswd file? Could see in the following link mention of setting "remember" to 0 has no effect to remember value in "/etc/security/opasswd" file. =https://lists.fedorahosted.org/pipermail/linux-pam-commits/2011-June/000060.html

• Ubuntu based VPN server behind NAT router?

  - by maartenn88

  I have a small intranet- and file-server inside our company, which can only be reached from inside our own network. I'd like to be able to reach the intranet and files on the server from outside the network, however I don't really like the idea of completely opening security by forwarding the ports on our NAT-router, so I'd prefer to enable a VPN possibility for this. So I have a router, which is the DHCP server and has NAT function, and I have an Ubuntu Server with the files and intranet on it. How do I configure these two so that I can make a VPN connection with my network in order to reach the server? thanks in advance for any answer!

• I installed DKIM and SPF. Do I need to install Domain Keys as well?

  - by johnlai2004

  I have linux apache mysql and php server. My website uses the php mail() function and the server's postfix server to email other people. I successfully installed SPF and DKIM on my server to reduce the likelihood of my website's email-outs from ending up in people's spam boxes. In my research, I stumbled on Domain Keys which seems to be a "historical" version of DKIM. Do the big web mail services like Google, Yahoo and Hotmail still use Domain Keys? If not, then maybe I don't need to install it?

• How can I make the NetworkManager work?

  - by Yang Jy

  I am running a version of RHCE6 on my laptop, and lately I've been trying various stuff about network configuration through command line. Last night, I tried removing the NetworkManager using "yum remove NetworkManager" from the system, so that I could have more control of the network through the command line. But the result is, I didn't manage to configure the wireless connection through wpa_supplicant, and I need wireless connection during my travel to another place. So I need the wireless function back as soon as possible. I typed " yum install NetworkManager", some version installed, but I don't get to have an icon on the taskbar, and of course, the network doesn't work. The package I previously removed(about 24MB) was much larger that the one I just installed(about 2MB), so I think some dependencies must be missing. How could I install all these dependencies? Please help!

• LUKS-Encrypted Root Partition in Ubuntu 9.04

  - by Martindale

  I have a LUKS-encrypted root partition that I have installed Ubuntu 9.04 to. I have of course placed /boot on a separate ext2 partition, and my boot loader loads and functions correctly. However, I can't seem to get my initrd to load the LUKS-encrypted root using the appropriate /dev/mapper/ address. What hooks and scripts do I need to add to get this to function correctly, and what is the correct way to regenerate my initrd? I can CHROOT into this install, and everything works fine - but I just can't seem to get it to actually boot. Help!
