• Can't find disk usage in one directory

  - by Xster

  Similar questions are asked frequently but no suggested answers solved my issue. I have some disk space usage that I can't find as well. In df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 144183992 136857180 2652 100% / udev 2013316 4 2013312 1% /dev tmpfs 808848 876 807972 1% /run none 5120 0 5120 0% /run/lock none 2022116 76 2022040 1% /run/shm overflow 1024 0 1024 0% /tmp I checked the inodes, I checked lsof for +L1 or deleted files, I rebooted, I checked for files hidden behind mounts but none of them were the issue. It grows periodically and I'm running out of things to delete to feed the beast. It's all in the home directory of the only user I have.

• How do i tell if my drivers are up to date on Acer?

  - by joe

  Hoping some kind souls can help me out ? I got a blue screen the other day after trying to load sandboxie. So its obviously conflicting with something. I checked if my drivers were up to date on my acer aspire one AOD270 on this intel based site; http://www.drivermanager.com/en/down...tel&Logo=intel Its showing i have 2 drivers that need updating ; Intel NM10 Express chipset and the Realtek PCIE Cardreader. I have no idea whether to do the update via the Intel Driver update site or the Acer drivers download page? I then ran Bluescreenview and on the dump file its showing ; ''caused by driver'' igdkmd32.sys ''file description'' Intel (R) WDDM Kernel mode driver ''product name''Intel Graphics Accelerator Drivers for Windows 7(R) I bought the laptop here in SE Asia about a year ago. The ''HOT!! NEW download tool'' on the acer drivers site (below) doesnt seem to work and the info about removing and installing drivers is limited. Not sure what to trust on non acer/manufacturer sites. http://support.acer.com/us/en/produc...1&modelId=4040 I've located the igdkmd32.sys file inside the INTEL GRAPHICS MEDIA ACCELERATOR 3600 SERIES 8.14.8.1064. When i click on ''update driver'' in control panel it searches and says its up to date. In windows maintenance it says this intel had a problem, but no solution. For all i know my drivers could be up to date and its something else. Can anybody advise a dummy step by step the process i should follow ? I've never done this before. eg do i delete the old driver first and then download the new one.how much of a problem i could cause by downloading this type of thing wrongly? As yet i havent downloaded any drivers. I've asked on other forums but no luck as yet. Thanks for any help!

• Exchange eMails In A Mailbox Appear To Be Blocked By A Dud Message

  - by John Judd

  I have a client with an Exchange server on which there are quite a few mailboxes. One mailbox in particular is causing some problems. When an email from a certain address arrives, it appears to prevent Exchange from successfully delivering the email to the Outlook Express inbox. The address in question is from an account with Bigpond, or at least I think it is, I didn't check to see if it was spoofed (only just occurred to me.) Any emails in the queue before the suspect email are delivered, then Express times out. When send/recv is retried those emails are re-received and the process times out again. The process I have for fixing this is to log in to the sever, load Outlook, open the recipients inbox, and delete the suspect email. Then retrying the send/recv on Express successfully retrieves all the messages (except for the deleted message.) This solves the immediate problem, but this has happened several times now, and each time requires the process above to correct it. What I am wondering is if there is anything I can do to fix this permanently. It seems to me that Exchange should reject a dud email message rather than getting stuck. Does anyone know what could be causing this, and how I can fix it?

• How Could My Website Be Hacked

  - by Kiewic

  Hi! I wonder how this could happen. Someone delete my index.php files from all my domains and puts his own index.php files with the next message: Hacked by Z4i0n - Fatal Error - 2009 [Fatal Error Group Br] Site desfigurado por Z4i0n Somos: Elemento_pcx - s4r4d0 - Z4i0n - Belive Gr33tz: W4n73d - M4v3rick - Observing - MLK - l3nd4 - Soul_Fly 2009 My domain has many subdomains, but only the subdomains that can be accessed with an specific user were hacked, the rest weren't affected. I assumed that someone entered through SSH, because some of these subdomains are empty and Google doesn't know about them. But I checked the access log using the last command, but this didn't show any activity through SSH or FTP the day of the attack neither seven days before. Does anybody has an idea? I already changed my passwords. What do you recommend me to do? UPDATE My website is hosted at Dreamhost. I suppose they have the latest patches installed. But, while I was looking how they entered to my server, I found weird things. In one of my subdomains, there were many scripts for execute commands on the server, upload files, send mass emails and display compromising information. These files had been created since last December!! I have deleted those files and I'm looking for more malicious files. Maybe the security hold is an old and forgotten PHP application. This application has a file upload form protected by a password system based on sessions. One of the malicious scripts was in the uploads directory. This doesn't seem like an SQL Injection attack. Thanks for your help.

• Windows CE restores default configuration after restart (Motorola MC3190)

  - by jarek

  Good morning, everyone! I have a problem with Motorola MC3190 hand scanner running on Windows CE. I've got few of those to make a new program for some kind of warehouse. There is already installed program which have been used by the customers before, so I delete this one and instead I install my new software which I've just made. It is running very well, but when I take out the battery and leave the device for entire night without power supply, it restores the whole configuration, so the old program is back, the wireless configuration is back and... Yeah. The scanner is restored to the configuration which was running when I received it few weeks ago. What I want to do is to set the whole configuration of the scanner so after a long power-off my program and my configuration will be restored. I truly believe someone knows how to do it. The time is running out, and I believe that the customer will be kind of annoyed when he will change the battery and the program which he bought will be gone. ;-) Regards, Jarek

• How to keep Ubuntu 11.10 and Kate editor w/terminal from changing command line when changing tabs?

  - by Kairan

  I am programming C using Kate editor in Ubuntu 11.10. It works great, but when I change tabs in Kate, the terminal line changes to the file path of the tab I click on. Normally this is not a big deal (other than annoyingly adding extra text to my terminal) however if I am currently RUNNNING a C program, it obviously will type at the command line, which is not so cool. Example terminal window for my C program (its at a menu): 1) select opt 1 2) select opt 2 Enter choice: (here it waits for prompt from user) Now when I click a tab in Kate, it wants to put in the cd / path of the file in that tab, such as: cd /home/user/os/files And of course since my terminal was waiting for prompt from user it gets that command.. not good. Perhaps there is no fix, but maybe someone knows? Obviously I could choose NOT to switch tabs or end program before switching tabs... Note: I probably made the mistake of putting this under StackOverflow which is more of a programming area - so though repost here might be best (I am not sure how to link the questions but will paste hyperlink to that post - I dont want to violate any stackoverflow/superuser violations) Suggestions on merging them are welcome or if I should delete one?

• what is uninstall procedure for software installed via "make install" on CentOS 6.2

  - by gkdsp

  I installed OCILIB on my CentOS 6.2 server some time ago, and now I want to install a newer version. The vendor requires an uninstall, but doesn't provide instructions. I'm guessing that's because it's trivial for people with a Linux background. http://orclib.sourceforge.net/doc/html/group_g_install.html If I installed this software using: step 1: # ./configure --with-oracle-headers-path=/usr/include/oracle/11.2/client64 --with-oracle-lib-path=/usr/lib/oracle/11.2/client64/lib step 2: # make step 3: # su root step 4: # make install step 5: # gcc -g -DOCI_IMPORT_LINKAGE -DOCI_CHARSET_ANSI -L/usr/lib/oracle/11.2/client64/lib -lclntsh -L/usr/local/lib -locilib conn.c -o conn How would I go about uninstalling this? I tried following this http://www.cyberciti.biz/faq/delete-uninstall-software-linux-commands/ but nothing was found on my disk using rpm -qa *oci* or yum list *oci*. Maybe since it wasn't installed with yum or rpm then I shouldn't expect either of these to find it. Are there generic instructions for uninstalling software on Linux that I could use, or do the instructions really depend on the specific software? Any help much appreciated.

• Windows 7 DHCP Default Gateway not Overridden by manual Default Gateway

  - by dgwilson

  We have recently installed Windows 7 for student computers. All student computers must be routed through our content filter which is located at 192.168.0.63. This was done in WinXP by adding a Default Gateway in the network adapter settings TCP/IP Properties Advanced Default Gateway. All teacher computers are routed through the DHCP assigned Default Gateway of 192.168.0.1. In WinXP the dhcp default gateway was correctly overridden by this manual setting. In Win7 it appears that the dhcp default gateway is retained and the manual one is added to the list so that there are two with the dhcp one having the primary metric. I have tried several ways to remove the dhcp default gateway such as, running the "route delete 0.0.0.0 192.168.0.1" command. Doing this from an administrator command prompt works but it just resets upon reboot. I've tried adding this command to the registry's Run section but it seems to run as a non-administrator and therefore will not complete successfully. Is there any way to prevent this and force the manual default gateway to override the dhcp one? Or to remove the dhcp assigned one automatically on boot/login? HELP! We CANNOT allow student computers to connect to the internet without going through the content filter.

• PHP extension causes symbol lookup error

  - by Christian

  Dear, I installed - or better tried to - the NMCryptGate Extension for PHP on my Debian 5.0.8 server. I did this by compiling the sources which came up with no error message. Calling phpinfo() I can see the extension as enabled. BUT, whenever I try calling a method from this extension I get an error logged to the apache error log: /usr/sbin/apache2: symbol lookup error: /usr/lib/php5/20060613+lfs/nmcryptgate.so: undefined symbol: nmlistalloc What is missing? I got two packages from the software company: the php module sources and some files which should - according to their path inside the tar - go to /usr/local/bin|doc|include|lib. I moved them there without any effect. Each of these two packages has its own config file almost looking the same: \# libnmcryptgate.la - a libtool library file \# Generated by ltmain.sh - GNU libtool 1.3.4 (1.385.2.196 1999/12/07 21:47:57) \# \# Please DO NOT delete this file \# It is necessary for linking the library \# The name that we can dlopen(3) dlname='' \# Names of this library library_names='libnmcryptgate.so.1 libnmcryptgate.so libnmcryptgate.so' \# The name of the static archive old_library='' \# Libraries that this one depends upon dependency_libs=' -L. -L/usr/ssl/lib -L/usr/local/ssl/lib -L/usr/local/lib -lssl -lcrypto' \# Version information for libnmcryptgate current=1 age=0 revision=29 \# Is this an already installed library installed=yes \# Directory that this library needs to be installed in libdir='/usr/local/lib' I tried several ways to get it right: moving files, symlinking, changing configurations - always followed by restarting apache - no success. I guess I just have to move the files to the correct location or change the libdir inside the config files but meanwhile I'm totally confused by the two packages: do I need both, which config rules what, do I have to use the libdir variable? And for what? ... Anybody out there hinting me to my source of failure? Thank you in advance, regards, Christian

• Authenticating Active Directory Users to Mac OS X Mavericks Server L2TP VPN Service

  - by dean

  We have a Windows Server 2012 Active Directory Infrastructure that consists of two domain controllers. Bound to the Active Directory Domain is a Mac OS X Mavericks Server 10.9.3. The server runs Profile Manager and VPN Services. My Active Directory users are able to authenticate to the Profile Manager, but not the VPN. I have found several threads on other forums of other users reporting similar issues, here is just one of many references: https://discussions.apple.com/thread/5174619 It appears as though the issue is related to a CHAP authentication failure. Can anyone suggest what next troubleshooting steps I might take? Is there a way to liberalize the authentication mechanism to include MSCHAP? Here is an excerpt of the transaction from the logs.

• How to edit a read-only document in LibreOffice?

  - by TestUser16418

  I need to fill a form (which I received in .doc format and saved as .odt). The file is read-only except for the fields where I can enter the information. Unfortunately, with the fields filled it doesn't fit on one page, and I need to edit it so I can print and submit it. With LibreOffice beta 3, I could edit anything outside of the fields, and the fonts were slightly smaller, so it fit on the page even with the fields filled. Today I upgraded LibreOffice, and when I opened to edit a field where I had a mistake, it no longer fits on the page, and I can't edit it. When I opened the properties it says that the document is NOT read-only, but it is. When I try to delete text it tells me that I can't edit the read-only content. Can anyone give me some advice, because I've been trying to print my form for 2 hours already. I tried AbiWord and KWord, but both are missing elements from the page (though the forms fit). I can also edit the margins (Format - Page is dimmed, but when I begin to edit a field it's no longer dimmed)med

• Exchange users moved mailbox now can't open some calendars

  - by Kip

  OK So the environment is Exchange sp on Windows 2003 server. This weekend we had to move a bunch of users of off one information store that was corrupt and onto a temp store delete the original dodgy store and then move the users back from the temp store to one of the three other stores under the same original storage group. Since then we are having some weird access issues relating to calendars. I am assuming it is all related, but it might not be. The problem is that users are unable to see any calendars that they have previously had access to. The weird thing is, that some of the users in question are not ones who have been moved nor are they trying to access calendars that belong to people whose accounts have been moved. Hence my assumption its related but possibly not. The message received is "Unable to display the folder. The calendar folder could not be found." here is the kicker, if i move someone who is trying to access other calendars, to a different mailbox store (thereby creating a new email account and sending stuff over), things start to work again. this to me indicates a permissions problem however I am unsure in what way. Looking for help out there please guys :) Cheers

• Two instances of Windows Vista on boot up after failed clean install

  - by Dwayne

  I tried to install a clean version of Vista but failed. I ended up with Windows and Windows.old on my C: drive and a dual boot option on boot up. I gave up and booted up the old version and tried to rename the Windows.old to Windows and was asked if I wanted to merge the two folders. I answered yes and all seemed OK until I booted up this morning and was given the choice of two versions of Vista. The first one is the one that failed to installed correctly and the second one is the old version. How can I get rid of the failed installation? I got rid of the bad boot via MSCONFIG. Here is my current situation: several hard drives installed Using C: as my boot drive a much larger drive (H:) for storing most of my files. I found a subfolder in my C:\windows folder named windows. Upon inspection I determined it to be older than the C:\windows folder and therefore it must be the older, working version of the boot. I renamed the C:\windows folder to c:\windows.bad and moved the sub windows to the C: root directory. I also copied it to the h: drive. Now MSCONFIG reports that the copy that is booting is the h: copy. How can I change it back to the C:\ copy and can I delete the C:\windows.bad file set?

• Ubuntu: Getting rid of a mimetype entry

  - by Epaga

  I have a pesky mimetype entry that I can't seem to get rid of. Here is the current situation: xdg-mime query filetype myfile.mfe application/pesky Using assogiate I have found out the information about this mime type entry (but can't delete it there). I have the following 'pesky.xml' XML file which was used to create the mime type (as far as I can tell, since it exactly matches the entry in assogiate...): <?xml version='1.0'?> <mime-info xmlns='http://www.freedesktop.org/standard'> <mime-type type="application/pesky"> <comment>my pesky type</comment> <glob pattern="*.mfe"/> <magic priority="100"> <match type="string" offset="0" value="application/pesky"/> </magic> </mime-type> <mime-info> However, the following has no effect: sudo xdg-mime uninstall --mode system --novendor pesky.xml The file association remains. Any ideas?

• Can not copy files from NTFS partition

  - by Ali

  I am experiencing a weird problem. I was running Xubuntu on my laptop until yesterday that I had to delete Xubuntu and install Windows. I had a NTFS partition on my Xubuntu that I kept some files on it. Today after installing windows I wanted to move all the files from that partition to an external HDD. I selected all files and folders and clicked on Copy, then I went to the HDD and clicked on paste but nothing happened. I can not do that. I do not know why. I copy the files, and wherever I click paste, nothing happens. If I try to copy the files and folders one by one, I can copy some of them, but some of them do not move. The other problem I have is that I can not open some files, in particular pdf files. When I click on pdf files I get this error: There was an error opening this document. This file cannot be found. Also, I cannot play some mp4 files. I can not open some jpg and txt files. I get this error The directory name is invalid. So in summary, after removing Xubuntu and installing windows 7 I have the following problems with one of the NTFS partitions on my internal drive: Can not copy or cut all folders and files from that partition to any other partition - I also do not get any errors. Can copy some folders and files Can not access some pdf, jpeg, txt and mp4 files and get the above errors. I should also mention I did not change anything for this partition during the installation or formatting the other partitions.

• System Center Essentials server running out of disk space due to stored old updates

  - by Ricket

  We have a System Center Essentials (SCE) server to filter updates to our laptops. We've configured it to download the update, and then the laptops get the update from this server; this of course reduces our internet bandwidth and the time it takes for employees to receive the updates, which reduces the complaints we get about how long updates take. However we currently have a total of 2,255 updates stored on the server. SCE gives a breakdown: Updates with installation errors: 29 Updates needed by computers: 280 Updates installed/up-to-date: 0 Updates with no status: 1946 Our little server has 68gb of hard disk space, and the updates are currently taking 32gb and counting. Some of the updates date back to 2003, but we can't figure out a way to delete them to free up space on the server. Right-clicking an update and clicking Uninstall threatens to remove the update from all computers, which is not what we want. Some of the updates even inform us upon viewing: This update has been replaced by a newer update. Before declining this update, it is recommended that you approve the new update first and verify that this update is no longer needed by any computers. How do you prevent your SCE server from filling its hard drive space? Is there a way to configure the server to only keep updates that are still needed? Furthermore, why (in the above breakdown of updates) are there so many updates with "no status" and 0 updates that are "installed/up-to-date"?

• Hardening non-root standalone Linux Tomcat install

  - by NoozNooz42

  I want to know if you have any tips as to how to strengthen the security of a non-root install of Tomcat in standalone mode once Tomcat is already installed in a non-root account, in standalone mode. I precise this because, for example, I'm not at all interested by the answers given here (because both Java and Tomcat requires root priviledges there to be installed and I've got zero interest in running jsvc): http://serverfault.com/questions/43765 So far, here's what I've done for my non-root standalone Tomcat 6 install: download and install the JRE .bin provided by Oracle/Sun (no need to be root here) (no need for a full JDK anymore right seen that Jasper [Tomcat's JSP engine] has its own compiler now right?) download and tar -xzf tomcat 6 (no need to be root here) set up transparent port-forwarding (must be root here) Note that my distribution is a Debian one and I have exactly zero interest in downloading Debian package / backports / whatever... Because, once again, I DO NOT want to need to be root to install Java & Tomcat. The only moment I needed to be root was to configure the firewall to transparently do the port forwarding 80 <-- 8080 and 443 <-- 8443. I then deleted all the default webapps but one: cd ~/apache-tomcat-6.0.26/webapps rm -rf docs rm -rf examples/ rm -rf manager/ rm -rf ROOT/ What about the directory ~/apache-tomcat-6.0.26/webapps/host-manager, do I need it or can I delete it? So, once I've installed Tomcat standalone in a non-root account (and taken into account that I don't want to enter the root password anymore and that I don't plan to install the whole Apache shebang), what more can I do? Are there connectors I can disable? (how?)

• Rsyslog stops sending data to remote server after log rotation

  - by Vincent B.

  In my configuration, I have rsyslog who is in charge of following changes of /home/user/my_app/shared/log/unicorn.stderr.log using imfile. The content is sent to another remote logging server using TCP. When the log file rotates, rsyslog stops sending data to the remote server. I tried reloading rsyslog, sending a HUP signal and restarting it altogether, but nothing worked. The only ways I could find that actually worked were dirty: stop the service, delete the rsyslog stat files and start rsyslog again. All that in a postrotate hook in my logrotate file. kill -9 rsyslog and start it over. Is there a proper way for me to do this without touching rsyslog internals? Rsyslog file $ModLoad immark $ModLoad imudp $ModLoad imtcp $ModLoad imuxsock $ModLoad imklog $ModLoad imfile $template WithoutTimeFormat,"[environment] [%syslogtag%] -- %msg%" $WorkDirectory /var/spool/rsyslog $InputFileName /home/user/my_app/shared/log/unicorn.stderr.log $InputFileTag unicorn-stderr $InputFileStateFile stat-unicorn-stderr $InputFileSeverity info $InputFileFacility local8 $InputFilePollInterval 1 $InputFilePersistStateInterval 1 $InputRunFileMonitor # Forward to remote server if $syslogtag contains 'apache-' then @@my_server:5000;WithoutTimeFormat :syslogtag, contains, "apache-" ~ *.* @@my_server:5000;SyslFormat Logrotate file /home/user/shared/log/*.log { daily missingok dateext rotate 30 compress notifempty extension gz copytruncate create 640 user user sharedscripts post-rotate (stop rsyslog && rm /var/spool/rsyslog/stat-* && start rsyslog 2&1) || true endscript } FYI, the file is readable for the rsyslog user, my server is reachable and other log files which do not rotate on the same cycle continue to be tracked properly.

I was thinking about having 5 tables (EMPLOYEE, SKILLS, PROYECTS, SALARY, PROFESSION) but I guess there is a better way of doing this. create table Employee ( PRIMARY KEY [Person_ID] int(10), [Name] varchar(30), [sex] varchar(10), [address] varchar(10), [profession] varchar(10), [Skills_ID] int(10), [Proyect_ID] int(10), [Salary_ID] int(10), [Salary] float ) create table Skills ( PRIMARY KEY [Skills_ID] int(10), FOREIGN KEY [Skills_name] varchar(10) REFERENCES Employee(Person_ID), [Skills_pay] float(10), [Comments] varchar(50) ) create table Proyects ( PRIMARY KEY [Proyect_ID] int(10), FOREIGN KEY [Skills_name] varchar(10) REFERENCES Employee(Person_ID) [Proyect_name] varchar(10), [working_Hours] float(10), [Comments] varchar(50) ) create table Salary ( PRIMARY KEY [Salary_ID] int(10), FOREIGN KEY [Skills_name] varchar(10) REFERENCES Employee(Person_ID) [Proyect_name] varchar(10), [working_Hours] float(10), [Comments] varchar(50) ) So to get the total amount of the cost of a project I would just sum the working hours of each employee envolved and sum some extra costs in an aggregate query. Is there a way to do this in a more efficient way? What to add or delete of this small model? I guess I am missing something in the salary - maybe I need another table for that?

• Embedding a WMV file on the web via URL in a Powerpoint presentation

  - by Dave

  I've got a situation where I want to distribute a Powerpoint presentation to several people. I want to be able to embed several large videos in this presentation by linking to a URL, for the following specific reasons: the videos are highly confidential, and I would like to be able to delete them at some later date, but still allow them to see it in the presentation while it is online. I want to send the presentation via email (so it should be small), and put the links on a server with a faster upload speed Maybe I'd like to change the video at some point without changing the presentation One option that addresses #1 is to hook up a webcam and allow them to see video stream from the office, but our upload rate is too slow for this to be a viable option. I've tried embedding a video and giving Powerpoint the URL. It seems to work initially, because the first frame appears in my slideshow. However, when I play the slideshow, nothing happens. I looked at the network traffic on my computer, and nothing was getting downloaded from the remote server. Any suggestions on how to make this work, or how to at least satisfy the criteria listed above would be great!

• WinPcap/Wireshark install: where is packet.ddl?

  - by Annonomus Penguin

  I have Wireshark installed, and I'm getting this error: The NPF driver isn't running. You may have trouble capturing or listing interfaces. I realize this is something to do with WinPcap. It's not in control panel, as the FAQ states it should be. I've tried installing it, and it says that there is a previous version installed. This leaves me to believe this is the problem: To be absolutely sure that WinPcap has been installed, please look at your system folder: you should find files called packet.* and wpcap.dll. Please check the file dates: these should be compatible with the WinPcap release dates. We've had reports of trojans or other malware that silently install the WinPcap driver, NPF.sys. If you've been infected by them, you'll probably see the driver file in Windows\System32\Drivers, but no entries in the "Add or Remove Programs" applet and no dlls. I've searched my hard drive, but the only path is this: C:\Windows\SysWOW64\packet.dll Is this the file they are talking about? Should I delete this file? I'm not quite sure, so I thought I'd verify that this file is the right one.

• Tell VLC where to look for plugins.dat file

  - by puk

  I am trying to build vlc from source (I will include installation script below), but when I try to run vlc I get the following error main libvlc warning: cannot read /home/user/downloads/vlc3/vlc/src/.libs/vlc/plugins/plugins.dat (No such file or directory) Why is it even looking in that non existant directory? The plugins.dat file is in /usr/lib/vlc/plugins/. I tried export VLC_PLUGIN_PATH=/usr/lib/vlc/plugins/ But it still looks in that non existent path. I can create a symbolic link, but that is a terrible way to do it. If in 6 months I delete my downloads folder, all of a sudden my vlc will break. Here is the script I am running to install: ./configure --enable-rpi-omxil --enable-dvbpsi --enable-x264 --enable-xcb --with-x --enable-xvideo --enable-sdl --enable-avcodec --enable-avformat --enable-swscale --enable-mad --enable-a52 --enable-libmpeg2 --enable-dvdnav --enable-faad --enable-vorbis --enable-ogg --enable-theora --enable-mkv --enable-freetype --enable-fribidi --enable-speex --enable-flac --enable-live555 --enable-caca --enable-skins2 --enable-alsa --enable-ncurses --enable-debug --enable-lirc --enable-live555 --enable-shout --enable-taglib --enable-vcdx --enable-realrtsp --enable-svg --enable-dvdread --enable-dc1394 --enable-twolame --enable-dirac --enable-aa --enable-jack --enable-bluray --enable-opencv --enable-sftp --enable-pulse --enable-projectm --enable-vsxu --enable-atmo --enable-glspectrum '--with-extra-libs=/usr/local/lib' '--with-extra-includes=/usr/local/include' '--x-libraries=/usr/local/lib' '--x-includes=/usr/local/include' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/info/' EDIT: I am using the following version: VLC media player 2.2.0-git Weatherwax (revision 2.1.0-git-1168-g5804dd1) And the --plugin-path option is no longer supported.

• Live Mesh starts exactly once on fresh Win7 Ultimate installation

  - by Reb.Cabin

  I did a fresh install of Windows 7 Ulimate 64-bit on a formatted drive on a refurbed Lenovo PC, applied all 102 (!) windows updates, windows seems to be working fine. No quirks installing, no apps, no junkware, just straight, legal, Win7 Ultimate right from an unopened 2009 Microsoft box. Ok, breathe sigh -- Install Live Mesh (no messenger, no mail, no writer, no photo, none of the rest of the Windows Live freeware). Set up my shares, let it run overnight. watch MOE.exe in the Task-Manager perf pane to make sure it's all settled down. reboot. Ok, check that MOE is running and files are getting updated properly from other machines in the mesh. Great. HOWEVER -- when I try to launch Windows Live Mesh app from the Start jewel, I get a brief hourglass, then nothing. Reboot. Same story. result -- the shares I already posted seem to be synching properly, but I can't run the app, so I can't add and delete shares. The background process MOE seems to run, but I can't get the app going. btw, the reason I did this fresh install is I had exactly the same experience running Vista, so I wiped the machine hoping it would solve this nasty problem. Imagine my surprise! Will be grateful for clues, advice, etc, please & thanks!

• Disabling Skype automatic update

  - by user13267

  How to stop skype from searching or at least downloading update without consent? I want that annoying "Update skype now" dialog box that keeps popping up before I log in to Skype and after I log in to Skype from appearing at all. Few months ago this used to work: 1) C:\Users\”YourName”\AppData\Local\Temp folder. 2) Find the file called SkypeSetup.exe, and delete it. 3) Create a text file in the folder, rename it to SkypeSetup.exe 4) Right click on the new file you just created and ask for properties. 5) Next left click the security tab then left click the advanced button. 6) Now left click “Change Permissions” and then “Add”. Enter “Everyone” (without the quotes) where it sez’, “Enter the object name to select (examples):” and click “OK”. 7) Now check the “Deny” box for “Full control” and click “OK”. obtained from HERE, but now it seems this has stopped working. The worst part is Skype seems to download ~30MB of executable setup file without my knowledge before bugging me with the dialog box to update it, and there seems to be no direct way to disable this download. And disabling the skype updater service does not seem to work either. Is there any kind of patch or registry hack I can use to stop skype from auto updating? Or should I start looking for an alternative to Skype altogether?
