• Openpgp does not work in my Thunderbird-Installation

  - by zerozero

  Hello community, as mentioned above - i encountered serious troubles. here are the versions of the related software: SuSE 11.2, Thunderbird v.3.1.6, released October 27, 2010, Firefox 3.6 v3.6.12 I created an installations with an own partition both for the user and for the TB-Mails. For a new installation on another hardware i took these partitions. When i wanted to read the emails, i got an error-message like this: The GPG-agent for your GnuPG-version 2.0.12 couldn´t get started Further i got an error message for the access on services of enigmail. The file jar:file:///usr/lib/mozilla/extensions/{3550f703-e582-4d05-9a08-453d09bdfdc6}/{847b3a00-7ab1-11d4-8f02-006008948af5}/chrome/enigmail.jar!/locale/de-DE/enigmail/help/initError.html couldn´t get found. I found out, that this path doesn´t come from TB nor from firefox, but from enigmail. I installed several (un-)pack-programs. the only effect was, that in the menu of TB the entry for OpenPGP appeared in the TB-Menu. The errors as described above repeat at every try to read an email. I deleted and re-installed enigmail, but the errors dont´t disappear. What can i do to get rid these error-messages ? Thanks in advance

• Black screen appears when booting new install of Ubuntu 11.10 on my desktop, cannot access Grub menu to fix

  - by izn

  I installed 11.10 on my desktop PC but get a black screen after the BIOS screen when I try to boot it. I was able to run 10.04.04 on my hard drive before installing 11.10 and I am also able to use 11.10 on my usb pendrive and CD ROM. I've tried unplugging all USB devices before booting and also upgrading from 11.10 to 11.10. Holding the shift key from the BIOS screen doesn't allow me to access the GRUB menu to try: Highlight the first entry, press “e” to edit it. Navigate to words “quiet splash”, delete them and type “nomodeset” in their place (without quotes). Press Ctrl + X to continue boot. Once on the desktop, go to System Administration Additional Drivers and activate the recommended drivers. So running 11.10 on my pendrive, I tried editing /etc/default/grub, commenting out the GRUB_HIDDEN_TIMEOUT setting by putting a '#' in front of it to display the grub menu and setting GRUB_TIMEOUT setting to a value greater than or equal to 1 e.g. GRUB_TIMEOUT=10. However, when I run sudo update-grub, I get: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?) I get the same error with update-grub after: sudo mount /dev/sda1 /mnt and after: sudo grub-install --root-directory=/mnt /dev/sda reboot sudo update-grub Other suggestions to fix the update-grub problem: Open synaptic, then purge all the related grub installed packages and reinstall grub-pc then and finally: sudo update-grub Or use Grub Customizer http://ubuntuforums.org/showthread.php?t=1195275 What would be the best way to approach this? I'm concerned about purging "all the related grub installed packages" but if it's true some files are corrupted this would seem necessary. Also, was I executing the correct commands i.e. with mount and grub-install, before running grub-update?

• Permission denied when running Rails app in VirtualBox Ubuntu guest with files on Windows host

  - by Ola Tuvesson

  I think I'm close to having my dev environment set up exactly the way I want, but one final snag remains. I'm running VirtualBox on a Windows 7 64bit host, with my dev enviroment inside a Ubuntu 12.04 guest. I want to keep the files for my projects on the host filesystem - partly so I can access them when the Ubuntu guest is not running, but also so I can use Tortoise and other Windows based tools (cough Photoshop), and it also eases my backup scheme somewhat. So I've got a folder "Rails" on my NTFS drive, which I've shared (Samba) from the host with a user specifically created for the Ubuntu guest. The mount point has been set up and an entry added to fstab (cifs), using a credentials file and the options iocharset=utf8,mode=0777,dir_mode=07??77 This mounts fine and my Ubuntu user has both read and write permissions to the contents. But when I try to start my Rails app I get permission errors on any files the app needs to write to (e.g. the log file) - why is that? Are there any major conceptual flaws with this approach? Would I be better off using the VBox "shared folders" function?

• How do I keep a table up to date across 4 db's to be used in SQL Replication Filtering?

  - by Refracted Paladin

  I have a Win Form, Data Entry, application that uses 4 seperate Data Bases. This is an occasionally connected app that uses Merge Replication (SQL 2005) to stay in Sync. This is working just fine. The next hurdle I am trying to tackle is adding Filters to my Publications. Right now we are replicating 70mbs, compressed, to each of our 150 subscribers when, truthfully, they only need a tiny fraction of that. Using Filters I am able to accomplish this(see code below) but I had to make a mapping table in order to do so. This mapping table consists of 3 columns. A PrimaryID(Guid), WorkerName(varchar), and ClientID(int). The problem is I need this table present in all FOUR Databases in order to use it for the filter since, to my knowledge, views or cross-db query's are not allowed in a Filter Statement. What are my options? Seems like I would set it up to be maintained in 1 Database and then use Triggers to keep it updated in the other 3 Databases. In order to be a part of the Filter I have to include that table in the Replication Set so how do I flag it appropriately. Is there a better way, altogether? SELECT <published_columns> FROM [dbo].[tblPlan] WHERE [ClientID] IN (select ClientID from [dbo].[tblWorkerOwnership] where WorkerID = SUSER_SNAME()) Which allows you to chain together Filters, this next one is below the first one so it only pulls from the first's Filtered Set. SELECT <published_columns> FROM [dbo].[tblPlan] INNER JOIN [dbo].[tblHealthAssessmentReview] ON [tblPlan].[PlanID] = [tblHealthAssessmentReview].[PlanID] P.S. - I know how illogical the DB structure sounds. I didn't make it. I inherited it and was then told to make it a "disconnected app."

• Problem running mysql client, cannot connect to mysql server

  - by ehsanul

  Edit3: Thanks for the help everyone. Sorry for wasting anybody's time, but it seems like a simple reboot solved it. I should've known better, but I just had the assumption that the "restart" solution is mostly valid just for MS Windows (no offense). I'll keep this in mind before I ask a question here again. I installed the mysql-client-5.0 and mysql-server-5.0 packages on Ubuntu 8.04, using sudo apt-get install. When I try to run the "mysql" command, I get the following error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) To verify that mysql server is running, I tried this, and it does seem to be running, with the correct socket too: $ ps aux | grep mysql root 13388 0.0 0.0 1772 528 ?

Note that I'm completely new to mysql. Edit: As requested in comments, the exact command that is returning the error is simply "sudo mysql". And when I check netstats for active networks services, I do see an entry for port 3306, with Protocol: tcp, IP Source: 127.0.0.1, State: LISTEN Edit2: It appears as if the /var/run/mysqld/mysqld.sock socket doesn't exist (if I'm interpreting the following output correctly): $ ls -al /var/run/mysqld/ total 0 drwxr-xr-x 2 mysql root 40 2009-08-06 06:36 . drwxr-xr-x 20 root root 860 2009-08-06 06:25 ..

• D-LINK 2450U DSL router: Port forwarding forwading to the modem itself, not the specified IP

  - by axk

  I found a similar question but it has no satisfactory answers. I have a D-LINK 2540U DSL router. It has a basic port forwarding(under DNS - Virtual Servers) configuration in the administration panel where you specify: external port range, protocol, internal port range, server IP address and it is supposed to forward that port to that IP address. When I first set it up for a Real VNC connection it worked fine, just as I expected. Then I added a DynDNS configuration entry in the router's 'Dynamic DNS' section and added an additional SSH (22) forwarding rule. The SSH forwarding also worked fine (now with the dynamic hostname, but I suppose it doesn't make any difference as far as SSH is concerned). Then I removed the SSH rule and after that the VNC forwarding stopped working with the VNC client failing to connect (I have tried to connect with telnet and it also failed to connect, so it wasn't a VNC problem). After adding a rule for port 80 it turned out it would forward on port 80 though not to the specified server IP but to the modem itself. At least it is what it looks like, because it gives me the administration panel when I connect to my external IP (both using a browser and plain telnet in which case I can see that it is mini_hhtpd sitting on the port, which is obviously the modem's administration panel). Have anybody encountered a similar problem with port forwarding? I have tried to do a reset through the administration panel and to restore a backup of the settings made before I started playing with port forwarding, but it didn't help. Should I do a 'hard' reset with the button on the modem? Is it any different from the administration panel's reset (Restore default)?

• DNS configuration issues. Clients inside network unable to resolve DNS server's name

  - by hydroparadise

  Setup the DNS service on Ubuntu 12.04 64 and all apears to be well except that my dhcp clients do not recognize my DNS servers hostname. When doing a nslookup on one of my Windows clients, I get C:\Users\chad>nslookup Default Server: UnKnown Address: 192.168.1.2 Where I would expect the FQDN in the spot where UnKnown is seen. The DNS server know's itself pretty well, but I think only because I have an entry in the /etc/hosts file to resolve. There's so many places to look I don't even know where to begin. Are there any logs I can look at? Something. Places I've looked at and configured: /etc/bind/zones/domain.com.db /etc/bind/zones/rev.1.168.192.in-addr.arpa /etc/bind/named.conf.local EDIT: '/etc/bind/zones/rev.1.168.192.in-addr.arpa' @ IN SOA dns-serv1.mydomain.com [email protected].

• Cant connect to MySQL server from Java application

  - by RN

  This is on VPS\Centos server. The MySQL server is pre configured. I am running the Java application on Tomcat My Java web application is not able to connect to the MySQL server. I get an error - "Caused by: java.net.ConnectException: Connection refused" I suspect this to be a configuration problem rather than a coding problem- hence I have posted this on ServerFault And yes, The same web-app is able to connect to MySQL on a different linux box This is the URL that I provided to my Java application (note- it assumes default port) url = "jdbc:mysql://localhost/pickupgames" My first suspicion was that I am running on a non-default port So I tried to find the port where mySQL server is running I tried every trick mentioned in http://serverfault.com/questions/116100/how-to-check-what-port-mysql-is-running-on But no luck ! SHOW GLOBAL VARIABLES LIKE 'PORT'; This shows port 0 netstat -tlnp doesn't show mysql at all /etc/my.cnf It has no port entry telnet localhost 3306 Doesn't connect And in case you are wondering if mysql server is running at all or not It is And I know for sure, because I have been able to login using the mysql command Also # ps -ef|grep 'mysql' root 31839 27662 0 00:49 pts/3 00:00:00 grep mysql root 32452 1 0 Apr02 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe --skip-grant-tables --skip-networking mysql 32504 32452 0 Apr02 ? 00:00:06 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --socket=/var/lib/mysql/mysql.sock --skip-grant-tables --skip-networking Please note the --skip-networking parameter Does this have something to do with the issue ? Any explanation why I cant connect to mysql server on port 3306 by telnet? Or why it docent show up under netstat? Any suggestion on whet I should try next ?

• Weird routing issue

  I'm having some weird internet problems on campus. I know it's something simple, but it's a case where I need another set of eyes.

  Possible Duplicate: Please insert a disk into SD/MMC - Vista problem Hi I tried pushing my 2GB micro SD card using the inbuilt card reader.

• OpenSSL response 404 issue on centOS 6

  - by dsp_099

  I followed this tutorial (though it's for 5.2, I figured I'd be alright). The changes I had to make that seemed to have worked: Rename ca.csr to ca.cslr (that's the one the command generated) List it in the ssl.conf as ca.cslr instead of ca.csr I have the following in the httpd.conf <VirtualHost *:80> DocumentRoot /etc/test ServerName site.com </VirtualHost> <VirtualHost *:433> SSLEngine on SSLCertificateFile /etc/pki/tls/certs/ca.crt SSLCertificateKeyFile /etc/pki/tls/private/ca.key <Directory /etc/test> AllowOverride All </Directory> DocumentRoot /etc/test ServerName cryptokings.com </VirtualHost> /test contains a folder inside of it, accessible via http://site.com/test/foo, however attempting to access it via https://site.com/test/foo results in warning that the certificate is untrusted (self-signed, no biggie) a 404 error. Chrome's complains about the certificate are the following: The identity of this website has not been verified. • Server's certificate does not match the URL. • Server's certificate is not trusted. I think those warnings are a side-effect of a self-signed certificate - or is the first one something that needs to be addressed? I seem to be able fetch the root page via https just fine though, it shows a standard CentOS setup page. (That said, I haven't added a VirtualHost entry for it so I suppose that makes sense) I think I've made a mistake somewhere during the setup as I'm not too familiar with the process. During setup, I was prompted for a type of password that would be required when apache restarts but running service httpd restart does not seem to prompt me for one. Any help would be appreciated.

• Windows 7 Black Screen On Boot, Seperate Bootable VHD Works Fine

  - by David Osborn

  I have a Window 7 x64 install with a bootable VHD (also Windows 7 x64). I was having problems getting my homeserver to do backups (VSS erred) so I ran check disk and used a tool from MS (cleanc2r.exe) to remove an empty Q drive from the VHD that I believe was a result of installing Office 2010 Beta. (All of this was done on the bootable VHD, not the main install.) Now I can't boot into the main install. It gets past the Starting Windows screen and then goes black. I can still boot into the bootable VHD and everything works fine from there. I have tried to boot the main install in Safe Mode/Safe Mode with Networking/and Safe Mode command prompt and it has the same issue. I ran chkdsk /r on the main install and after doing all the work there was a message about correcting some free space that was marked as allocated and also that it was unable to make an entry into the event log. I tried the startup repair utility and it found no problems. I don't see the setting for restore to last know good configuration so I couldn't do that. I don't recall installing anything new to the main install nor having hooked up any new hardware recently.

• Does Hyper-V support SCSI Pass-through discs in a Server 2003 R2 VM?

  - by Peter Bernier

  I'm running into some difficulties getting pass-through disks to be accessible to a Hyper-v server 2003 r2 virtual machine. Host OS : Server 2008 R2 full w/Hyper-V role Guest OS : Server 2003 R2 (Windows Home Server) The guest's OS disk is a pass-through disk on the IDE controller (not the best solution, but I can live with it). My storage disks will be pass-through disks on the SCSI controller. I'm able to see all of the disks that I'll be using for the VM on the host without issue. The problem that I'm having is that I can't seem to get the guest OS to be able to 'see' the storage drives (as pass-through disks on the SCSI controller). Here's what I'm doing : On the host, the storage drive is set to 'Offline' just like the OS disk (this is required for pass-through to work). In the VM, the storage drive is on the SCSI controller. Hyper-V Integration Tools are installed in guest. That's as far as I'm able to get. I don't see the drive in Computer Management, or in Windows Explorer (I've tried with an unformatted disk, as well as after formatting a partition). I am able to see a removable device that lists the disk's model number in the Guest, but I can't seem to access the storage. (I get an entry in Device Manager that needs drivers, but nothing on the Integration Tools disc works..) Trouble-shooting steps I've tried : If put the pass-through drive on the IDE controller, I can see it in the Guest. If put the storage drive 'Online' in the host and create a VHD on it on the SCSI controller, I can see it in the Guest. I suppose I could create a fixed-size VHD that consumes the entire disk, but I'd rather not have that overhead. I've also extracted the contents of the Integration Tools drivers (x86 and amd64) and tried pointing the disk controller to each of those, with no luck. Can anyone offer suggestions as to how I can get this to work properly?

• Server Names Inside Private Network

  - by thyandrecardoso

  Our office has a private network, where any requests on a (pre-determined) public IP are forwarded to a private IP inside said network. On that private IP, we've got a server running several services, including HTTP servers, and SCM systems. We only control our private network, having no control on the public IP configuration. We bought a domain name, and pointed it to that public IP, so people can access our services from the outside. But, when inside the office, people can't use that DNS name, because the server and any other hosts inside the network share the same public IP! For desktops, inside the office network, dealing with names is really easy: one entry on the hosts file and we're done. However, for laptops, that keep going in and out, and need to access services inside the office, the naming is really annoying. I don't know the "standard" process for dealing with these kind of situations. I've considered installing BIND in the office, and make people configure their wireless and wired connections to use that DNS server. What is the correct approach in this situation? If using BIND (or any other DNS server) is the answer, how should I configure it so that people inside the office can use it to get our custom names, and get forwarded to the ISP DNS when trying to reach the internet?

• Wiping Deleted Directory Entries and Defragmenting Directories

  - by Synetech inc.

  Hi, I have seen plenty of apps that wipe free space on a disk (usually by creating a file that is as big as the remaining space) or defragment a file (usually by using the MoveFile API to copy it to a new contiguous area). What I have not seen however is a program that wipes the deleted directory entries. That is, when a file is deleted, its information (name, dates, etc.) remain in the directory, but are simply marked as empty. That leaves all kinds of information in a directory entry, and also wastes space since (at least on FAT drives), the directory may be using several clusters. For example, if a directory once had a lot of files, it will be expanded to use another cluster which could be anywhere on the disk. This means that the directory is fragmented, and may be using more clusters than needed, possibly with 100’s of unused (ie, “deleted file”) entries between active files. Does anyone know of a program that can defragment/consolidate directories (ie, wipe unused entries, and move active entries together)? (I would really rather not have to resort to writing my own yet again.) Thanks a lot. EDIT Sorry, I should have said, Windows and/or DOS, for FAT*/NTFS.

• How do I fix a corrupt calendar cache?

  - by Blacklight Shining

  I was tailing /var/log/system.log and noticed a sudden wall of text. Looking closer, I saw it was an error CalendarAgent got while trying to save something: Nov 18 11:42:45 rainbow-dash.local CalendarAgent[12321]: CoreData: error: (11) Fatal error. The database at /Users/blackl/Library/Calendars/Calendar Cache is corrupted. SQLite error code:11, 'database disk image is malformed' Nov 18 11:42:45 rainbow-dash.local CalendarAgent[12321]: Core Data: annotation: -executeRequest: encountered exception = Fatal error. The database at /Users/blackl/Library/Calendars/Calendar Cache is corrupted. SQLite error code:11, 'database disk image is malformed' with userInfo = { NSFilePath = "/Users/blackl/Library/Calendars/Calendar Cache"; NSSQLiteErrorDomain = 11; } 2 messages repeated several times Nov 18 11:42:49 rainbow-dash.local CalendarAgent[12321]: [com.apple.calendar.store.log.subscription] [WARNING: CalSubscriptionSession :: persistError :: save failed] This entire sequence is repeated many times throughout the log. file said the file in question was a SQLite 3.x database, so I did a bit of searching and came up with a way to check those. blackl% cp -i ~/Library/Calendars/Calendar\ Cache /tmp blackl% sqlite3 /tmp/Calendar\ Cache SQLite version 3.7.12 2012-04-03 19:43:07 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> pragma integrity_check ; *** in database main *** Main freelist: Bad ptr map entry key=863 expected=(2,0) got=(5,21) On page 21 at right child: 2nd reference to page 863 This is followed by a few dozen lines like these: rowid <number> missing from index <name> and then: wrong # of entries in index <name> I'm at a bit of a loss as to what to do now—I couldn't find anything on how to fix the errors that I found. Also, it would probably be a good idea to disable Calendar Agent so it doesn't try to use the database while it's being fixed (that's why I copied it to /tmp before running sqlite3 on it.) How do I disable CalendarAgent and fix its cache?

• samba sync password with unix password on debian wheezy

  - by Oz123

  I installed samba on my server and I am trying to write a script to spare me the two steps to add user, e.g.: adduser username smbpasswd -a username My smb.conf states: # This boolean parameter controls whether Samba attempts to sync the Unix # password with the SMB password when the encrypted SMB password in the # passdb is changed. unix password sync = yes Further reading brought me to pdbedit man page which states: -a This option is used to add a user into the database. This com- mand needs a user name specified with the -u switch. When adding a new user, pdbedit will also ask for the password to be used. Example: pdbedit -a -u sorce new password: retype new password Note pdbedit does not call the unix password syncronisation script if unix password sync has been set. It only updates the data in the Samba user database. If you wish to add a user and synchronise the password that im- mediately, use smbpasswd’s -a option. So... now I decided to try adding a user with smbpasswd: 1st try, unix user still does not exist: root@raspberrypi:/home/pi# smbpasswd -a newuser New SMB password: Retype new SMB password: Failed to add entry for user newuser. 2nd try, unix user exists: root@raspberrypi:/home/pi# useradd mag root@raspberrypi:/home/pi# smbpasswd -a mag New SMB password: Retype new SMB password: Added user mag. # switch to user pi, and try to switch to mag root@raspberrypi:/home/pi# su pi pi@raspberrypi ~ $ su mag Password: su: Authentication failure So, now I am asking myself: how do I make samba passwords sync with unix passwords? where are samba passwords stored? Can someone help enlighten me?

• chrooting php-fpm with nginx

  - by dragonmantank

  I'm setting up a new server with PHP 5.3.9 and nginx, so I compiled PHP with the php-fpm SAPI options. By itself it works great using the following server entry in nginx: server { listen 80; server_name domain.com www.domain.com; root /var/www/clients/domain.com/www/public; index index.php; log_format gzip '$remote_addr - $remote_user [$time_local] "$request" $status $bytes_sent "$http_referer" "$http_user_agent" "$gzip_ratio"'; access_log /var/www/clients/domain.com/logs/www-access.log; error_log /var/www/clients/domain.com/logs/www-error.log error; location ~\.php$ { fastcgi_pass 127.0.0.1:9001; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/clients/domain.com/www/public$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; include /etc/nginx/fastcgi_params; } } It servers my PHP files just fine. For added security I wanted to chroot my FPM instance, so I added the following lines to my conf file for this FPM instance: # FPM config chroot = /var/www/clients/domain.com and changed the nginx config: #nginx config for chroot location ~\.php$ { fastcgi_pass 127.0.0.1:9001; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME www/public$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; include /etc/nginx/fastcgi_params; } With those changes, nginx gives me a File not found message for any PHP scripts. Looking in the error log I can see that it's prepending the root path to my DOCUMENT_ROOT variable that's passed to fastcgi, so I tried to override it in the location block like this: fastcgi_param DOCUMENT_ROOT /www/public/; fastcgi_param SCRIPT_FILENAME $fastcgi_script_name; but I still get the same error, and the debug log shows the full, unchrooted path being sent to PHP-FPM. What am I missing to get this to work?

• How to stop DW20.exe running on Win 2003 Server

  - by Laurence

  Periodically my ASP.NET application crashes (usually because memory consumption exceeds maximum allowed by application pool) and DW20.exe starts up. This is a big problem because it uses huge amounts of memory and CPU for minutes at a time. I want to know how to stop DW20.exe from running. Please note, I have already tried these often mentioned solutions: Disabling error reporting in Control Panel System Advanced Error Reporting Disabling the Error Reporting Service Modifying the registry as in http://support.microsoft.com/kb/841477 (however I might have done this wrong - this doc says "add a DWReportee value of 1" - what I did was add a DWORD entry with hexadecimal value of 1 - is this right? Also only 2 of the 4 keys were present, so I only modified these, e.g. there was no HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\PCHealth key at all) So, zero points for suggesting any of the above (unless you can see I have modified the registry incorrectly)! Also zero points for suggesting I resolve whatever is causing the application crashes :) - I am figuring this out, I just want something in the mean time to stop DW20.exe eating up all the server resources. By the way, this is a Windows 2003 SP1 server, with IIS 6 and SQL 2005 installed. There is no MS Office.

• Poor gaming performance with hyper-v installed in windows 8

  - by SnowCrash

  I am getting very poor gaming performance on my Windows 8 host OS with Hyper-V installed but no guest machines running. For example World of Tanks reports 60-70 FPS without Hyper-V installed and 4-14 FPS with it installed. A similar, dramatic, hit is observed in several other games so the issue is not WoT specific. To make the point clear, I am not trying to run games in a virtual machine. I don't even have a VM running while observing this effect. I simply have the Hyper-V feature installed. My system specs: AMD Phenom II 965 (3.4 GHz) AMD Radeon 6950 2GB (XFX Double D HD-695X-CDFC) 16GB DDR3 1333 AMD 790GX chipset Mainboard (Gigabyte GA-MA790GPT-UD3H) I have tried every AMD driver from 12.8 to the current 12.11beta8, virtualization is enabled in the BIOS settings, the onboard 3300HD video device is disabled in BIOS and I have read the MSDN blog entry here regarding a similar issue in Server 2008 that was resolved in 2008 R2 (and hopefully not regressed in Win 8). I'd like to be able to use Hyper-V for development and testing at home (I am a sysadmin/software developer professionally). If, however, I can't also use my home system for entertainment I'll have to scrap those plans.

• MacOSX: remove write-protect flag from file in Terminal

  - by Albert

  Hi, I have a file on a FAT32 volume which is shown as write-protected in Finder (so I cannot move it). Removing that write-protected flag in the information dialog works just fine. However, I have many more such files and I thus want to do it via Terminal. I already tried via 'chmod +w' but that didn't worked. 'ls -la' showed me that they are already just fine ("-rwxrwxrwx 1 az az " where az is my user account). Then I thought this might be stored in some xattr properties but 'xattr -l' didn't gave me any entry. Then I thought this might be some ACL setting (whereby I thought they would be stored as xattr but let's try it anyway) - and some Google search returned me something with 'chmod -a' or 'chmod -i' or so. All these tries only give me chmod: No ACL currently associated with file" or chmod: Failed to set ACL on file...: Operation not permitted". But I definitly have no write access to the file because I cannot move it or do any other change to it (in Terminal). Removing the write-access flag in Finder solves that.
