• Weird problem with Visual C++ 2010 Express

  - by Robert Vella

  This has happened before on my Vista Premium installation, and now it's happening on my Windows 7 Home Premium installation. Basically everytime I install Visual Studio Express 2010, it works fine for a random amount of time but then suddenly starts to hide from my sight -- that's the best way I can explain it. VS does not crash, and from what I can tell it does not freeze either; It continues to work, I can even "minimize" and "maximize" it; I simply cannot see it nor can I interact with it any meaningful way. Also: After the "crash" there are no logs in: Root\Program Files (x86)\Microsoft Visual Studio 10.0\Microsoft Visual C++ 2010 Express - ENU. Nor any other files created at the time of the crash. There are no traces in the event viewer. The program seems to be functioning perfectly in the process manager. If I reinstall Visual C++, it works normally for a seemingly random period of time before going cookoo again. I am stumped. This has never happened to me before, with any other program. And yet I doubt it really is a problem with Visual C++; More like something general that seems to have picked on it for some reason. Still, after a clean install with a new OS, I'm kinda thinking there's something wrong here. Any help would be appreciated, altough I suspect that the answer to this question will make me feel embarassed. P.S. Not sure if it helps, but I think around the same time I started having problems (On both installations) with windows turning off the display when I leave the computer, and then seemingly crashing when it turns it on again -- in fact when I interact with it it seems to be responding to my commands without actually display anything.

• Grub and Renaming... Why does Kubuntu 9.10 make it so hard?

  - by NH

  I'm trying to rearrange the grub menu in Kubuntu 9.10 (similar to this post), but unfortunately, Kubuntu includes the latest (and NOT greatest) version of grub, which no longer uses the elegant menu.lst. ARG! So anyway, I'm digging around in /etc/grub.d and I can't figure out how to rename the files in order to get them to boot in another order. (on a side note, I can't get xPUD to show up in the boot list... but that is a little less important) So why doesn't it work to do sudo grub in the terminal? (that seems to be the easiest option, but that doesn't work either.) Further, why can't I rename the files? Do I need to do it in the terminal? If so, how do I rename the file with the terminal? Can I run Dolphin (or Konqueror or whatever) as root (or su)? And don't tell me I need to try CHMOD first; I already tried that, and I still couldn't rename the file.

• GVIM hangs when saving through GVFS' FTP

  - by Lie Ryan

  I loved Gnome's Nautilus and FTP integration and being able to mount a remote FTP directory as a regular bookmark/directory, and double clicking any remote files to open in any unmodified program. I also loved editing text files with GVim. However, if I double clicked file on Nautilus to open a text file in Gvim, then saving a file will take about 10 seconds and GVim will hang for that amount of time. The major irritant is that I cannot continue editing while the text editor is waiting for the write to finish, this delay interrupted my workflow and thought process and saving becomes a painful process. The other problem is that I don't think simply uploading a file should take that much time. I'm aware of GVim's internal FTP support, but they are not as well integrated with Nautilus's FTP. So a few question: Is there a way to make GVim or GVFS to save in background while I continue editing? Why is GVFS so slow? Is there any way to set GVFS to use a single persistent FTP connection instead of creating a new FTP connection each time? I'm on Gentoo Linux x86-64.

• On linux, what does it mean when a directory has size 0 instead of 4096?

  - by kdt

  Here's a strange thing I haven't seen before -- a directory whose size is reported by ls as 0 instead of 4096, and I can't create any files within it. # ls -ld lib home drwxr-xr-x. 2 root root 0 Feb 7 03:10 home <-- it has zero size dr-xr-xr-x. 11 root root 4096 Feb 4 09:28 lib # touch home/foo touch: cannot touch `home/foo': No such file or directory <-- and I can't create files in it # rm home rm: cannot remove `home': Is a directory <-- look, it really is a dir So what does it mean for a directory to have size 0 instead of 4096? Filesystem is ext4 on fedora core 14. The output of mount is: /dev/mapper/vg_dev-lv_root on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0") /dev/vda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) Output of du -s /home: 0 /home Output of stat /home: File: `/home' Size: 0 Blocks: 0 IO Block: 1024 directory Device: 15h/21d Inode: 34913 Links: 2 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2011-02-07 03:45:46.188995765 -0800 Modify: 2011-02-07 03:11:59.980995019 -0800 Change: 2011-02-06 07:58:45.874995002 -0800

• Apache vhosts config: Host Name instead of IP Address

  - by Johe Green

  I have a domain (example.com) hosted at an external provider. I directed the subdomain sub.example.com to my ubuntu server (12.04 with apache2). On my ubuntu server I have a vhost setup like this. The rest of the config is basically apache 2 standard: <VirtualHost *:80> ServerName sub.example.com ServerAlias sub.example.com ServerAdmin [email protected] DocumentRoot /var/www/sub.example.com ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined WSGIScriptAlias / /home/application/sub.example.com/wsgi.py <Directory /home/application/sub.example.com> <Files wsgi.py> Order allow,deny Allow from all </Files> </Directory> </VirtualHost> When I enter http://sub.example.com in my browser my application shows up fine. But the domain is replaced by the IP address of my server. Do I have to configure my server somewhere else to deliver all its content under my domain sub.example.com?

• How can I setup nginx to serve virtualhosts with rails(unicorn/passenger) and php-fpm

  - by NewAlexandria

  I would like to serve multiple sites on one instance. I install nginx, php-fpm, and a rails app. I use sites like this to guide me. I configure php-fpm to listen to a local socket listen = /var/run/php-fpm/php-fpm.sock I configure ngnix with multiple hosts: include /etc/nginx/conf.d/*.conf I have several site php conf files like /etc/nginx/conf.d/site1.conf server { listen 80; server_name site1.com www.site1.com; root /var/www/site1; location / { index index.html index.php; } location ~ \.php$ { fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; } } and rails site conf files like upstream rails { server 127.0.0.1:3000; } server { listen 80; server_name site2.com www.site2.com; root /var/www/site2; location / { proxy_pass http://rails; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_set_header X-Url-Scheme $scheme; } } I have a unicorn rails server running via rails s -p 3000 Yet, no sites come up for either site1.com or site2.com. I can get to the rails site at www.site2.com:3000 What is wrong? I've spent 2 days (nearly 30hr) trying many different blogs, SO / SF questions, etc. Please share your insight or answer. edit 1: No log entries are created when I try to visit either site. It's like the requests never come in.

• Strange mysql problem moving website from Ubuntu server to Mac server

  - by evan

  I'm moving a website (php/mysql) from an Ubuntu server to a OSX 10.6 server. I've set up apache to run php scripts and setup the newest version of mysql on the mac. I just copied all of the php files and dumped/imported all of the mysql databases (including the mysql users database). When I visit the page being served on the Mac the page is able to connect to the database, but not query. Specifically this function mysql_error() is returning this error message NO SUCH FILE OR DIRECTORY The reason it's strange is that I'm able to change the php connection strings for mysql on the Ubuntu server so that it points to the Mac server and the page works correctly (so it seems mysql is correctly set up on the mac and definitely contains all of the users and tables it should). Thinking it was something to do with file permissions on the mac, I've changed all of the files 755 and it hasn't helped. Any ideas? Thanks!! UPDATE: I've found this error which I'm relatively certain is related to this problem in /var/log/apache2/error_log PHP Warning: mysql_query(): A link to the server could not be established

• Debian 6: setting up FTP just for website editing

  - by David Oliver

  I have a VPS using Debian 6.0. Currently, SSH is set to not accept password logins, and only key-based ones. A person who needs to work on one particular website (a vhost) wishes to use FTP. He doesn't need/want SSH. How can I set up FTP access for him, enabling him to have write permissions for all files in the relevant directory, and only the relevant directory? The directory is /srv/www/domainname.com/public_html Currently, all directories and files in that directory belong to www-data:www-data and are 644/755. I've installed vsftpd and have been reading some guides, but they all seem to deal with allowing multiple users to have their own user-named directories which isn't what I'm after. I can't seem to work out how to simply define one FTP user with a password that has access to one directory of my choosing. This is my first experience of setting up an FTP server. Thanks. Edit: have also found this - maybe I should be using ProFTPd, or can vsftpd also do what I want?

• Why are certain folders in my XP network share really, really slow?

  - by bikefixxer

  I have a workgroup set up with Windows XP. My file "server" is running XP Pro and the clients are running XP home. I've turned simple file sharing off on the server because certain clients need access to certain folders and not to others, and I want to keep it that way. Therefore, I've used the granular sharing/security settings to enable certain clients access to certain folders. I'm using the net use command in a batch file on the clients to add the share when they logon so it's always available via a mapped drive or a shortcut. On some clients "My Documents" points to the mapped drive, but all of the local and application settings stay local. Everything works well except for accessing a certain folder on the network. It contains a lot of random batch files and self-executable programs I use for diagnostics and what not, and nearly every time I open the folder the computer hangs for 15-60 seconds. This happens on every machine, including the server (but not nearly as often as the clients). I've searched high and low and cannot figure it out and it's driving me crazy. Here are all the things I've tried to no avail: Disabled firewall (XP) and anti-virus (ESET NOD32) Deleted any desktop.ini file I can find in the share Disabled "automatically search for network folders and printers" Disabled "remember each folder's view settings" Set HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer NoRecentDocsNetHood = 1 Tried with mapped drives and with UNC shortcuts Ran CHKDSK Removed Read-Only attribute from all folders (well, tried to remove, it always came back on with a half check) Added the server's static IP to the hosts file on the clients I've tried monitoring the server's performance to see if anything makes sense. Occasionally the issue coincides with a spike in pages/sec (memory) but not always. Other than that, everything else seems normal. The anti-virus would seem to be the most likely cause to me considering the batch files and what not, but it still hangs when it is completely disabled. I'm at a loss and if anyone can help me with this I'd greatly appreciate it!

• Trouble getting started with the STEALTH monitoring package

  - by dlanced

  Is anyone here familiar with the Linux-based STEALTH package (for monitoring FS integrity of client systems)? I'm trying to get started with a very simple configuration, but I'm running into trouble (this is running under Ubuntu 14.04): Config line `USE BASE/root/stealth/10.0.0.79' invalid STEALTH (2.11.02) started at Fri, 30 May 2014 15:25:00 +0000 Program terminated due to non-zero exit value for -type f -exec /usr/bin/sha1sum {} \; (EOC Fri May 30 15:25:00 2014 127) Stealth is creating a binary tmp file in the Stealth server root and generating a "report" file in the start directory, but not much else. Regarding the "USE BASE...invalid" error, and just to be sure, I manually created the directories in /root, but it didn't help. And, by the way, I am running stealth with sudo.

• Reliable backup software for windows network/samba shares.

  - by Eli

  Hi All, I have a Win2003 server that works as a pdc for a number of XP boxes, and a couple related FreeBSD boxes. I need to back up roaming profiles, non-roaming profiles via network shares, local hard drive data, and files on the FreeBSD boxes via samba shares. I have tried Genie Backup Manager and Backup4All pro, and both have excellent features, but both also begin to fail disastrously with more than a few days use. Mostly, the errors seem to have been from the backup catalog getting out of synch with itself. Whatever it is, there is no excuse for a backup software that says it backed up files when it really didn't, or the log saying it backed up exactly the same file 10,000 times in a single run, or flat-out crashing, or any of the other myriad problems I've run into with these. Really sad for products that fill such an important need. Anyway, does anyone know of a backup software that works reliably and can do the following? Scheduled backups for multiple jobs, without a user logged in. Backup from local hard drives or network shares. Incremental backups. Thanks! Edit: Selected solution: I've added my (hopefully final) solution as an answer.

• How do I push my initial snapshot to a subscriber server in SQL Server 2000?

  - by Kev

  I'm configuring Transactional Replication using the Push model. The scenario is: The SQL Servers: SQL01 (publisher) and SQL02 (subscriber) - both running SQL 2000 SP4. Both servers are standalone (i.e. not domain members) Both servers have their FQDN and NETBIOS names in their HOSTS files I've managed to configure SQL01 to publish my database and configured a Push subscription for SQL02 using the Push New Subscription wizard and set the Distribution Agent to update the subscription continuously. On the Push Subscription wizard "Initialise Subscription" page I've selected "Yes, initialise the schema and data" and ticked the "Start the Snapshot Agent to begin the initialisation process immediately" option. All the required services are running (SQL Agent). When I complete the wizard and browse the Replication - Publications folder I can see my publication (blue book with arrow). The publication shows the Push subscription and its status is Pending. If I look in the c:\Program Files\Microsoft SQL Server\Mssql\Repldata folder I see a number of T-SQL scripts for each table e.g. Products.bcp, Products.sch, Products.idx. What should happen now? Should my replicated database now (magically) appear on the subscription server?

• Why does Windows Event Log stop logging events before maximum log size is reached?

  - by Tuure Laurinolli

  I have a service that produces a lot of event log output. Currently the event log is configured to overwrite any old events to keep the log from ever getting full. We have also increased the event log size considerably (to about 600 MB). Recently the service started reporting errors to its clients, and the error message it was sending to its clients is "The event log file is full". How can this be, when event log is configured to overwrite as necessary? In our hurry to get the service back up we cleared the event log without saving its contents, but most likely it had not reached 600 MB yet, judging from sizes of some earlier log dumps. There is also MS KB entry 312571, which reports that a hot fix to a similar issue is available, but the the configuration that the fix applies to is not exactly the same we have. Specifically, the fix only applies if event logs are configured to never overwrite old events. I wonder if this has something to do with the fact that the log files apparently are memory-mapped. What happens if the system runs out of address space to map files to?

• What is the quickest and safest way to test new software and revert all changes, if needed?

  - by calbar

  I'm looking for Windows software that will allow me to quickly create a "checkpoint", do whatever I might need to do to my computer - install programs/drivers/updates, create/delete personal files, reboot the system multiple times, open questionable attachments - and then revert the entire system back to when the checkpoint was created. Essentially I want Windows Restore Points that save my personal files and partitions, too. It sounds like disk imaging might be the ticket, but creating them is much too slow and the restore process too involved... I'm hoping to sacrifice full disaster recovery for speed. Creating a checkpoint should be as close to one-click as possible, and rolling back should be a matter of selecting a restore point and rebooting. Ding! I'm familiar with Sandboxie, True Image Home "Try and Decide", Returnil, and a number of other "virtual system" apps that actively "catch" changes and allow you to commit or reject them. I'm not interested in these for a number of reasons - I prefer the "cut and dry" restore point approach. Finally, I'll note that I've just recently become aware of Comodo Time Machine. It sounds absolutely perfect, however, a quick skim through the user forums show more than a few horror stories of corrupted, unbootable systems. Any positive personal experience with the software to suppress my superstitions, or suggestions for more established alternatives would be greatly appreciated - Comodo Time Machine seems relatively new. Thanks for your help!

• How to correctly deploy Adobe Reader 9.1

  - by Ben Gillam

  Hi I have recently tried to deploy Adobe Reader 9.1 onto our network here. (SBS 2003 server and XP Workstations) I followed the instructions for the extraction of the installer and .msi and then creating a .mst transform file to set custom options. (Suppress EULA, dont create desktop icon etc) I then added the package to my deployment GPO applied the relevant .mst file and preceded to deploy accross the network. The software package is computer assigned to be installed prior to logon, to avoid user permissions issues. The package deploys correctly to computers and will run perfectly fine if you run from a shortcut, however when trying to view a pdf from within a web browser it fails with the following message. "The adobe acrobat/reader that is running can not be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again" I have found many pages on google refering to this problem, but none appear to be in relation the problems I have found. http :// kb2.adobe.com/cps/405/kb405461.html These fixes recommend correcting a registry entry (which i should mention is missing after the deployed installation. However this does not work. Switching off display in a browser - Seems to defeat the object of fixing the problem Removing old versions - There arent any. Trying with a different user - This affects all users of all privalige levels on all computers. On my workstation I uninstalled Acrobat Reader 9.1 then reinstalled manually using the same installation source files and it works fine. has anyone sucsessfully deployed AR9.1 on their domain and if so how? For the time being I have downloaded the older 8.1.3 release and deployed this in the same way which works fine, but would like to be using the up to date version. Thanks

• Scenario - NTFS Symbolic Link or Junction?

  - by Unsigned

  Differences Absolute Relative File Directory UNC Symbolic link ? ? ? ? ? Junction ? x x ? x Scenario Let's assume we're creating a reparse point to create the redirect C:\SomeDir => D:\SomeDir Since this scenario only requires local, absolute paths, either a junction or symlink would work. In this situation, is there any advantage to using one or the other? Assume Windows 7 for the OS, disregarding backward-compatibility (prior to Vista, symlinks are not supported). Update I have found another difference. Symbolic Link - Link's permissions only affect delete/rename operations on the link itself, read/write access (to the target) is governed by the target's permissions Junction - Junction's permissions affect enumeration, revoking permissions on the junction will deny file listing through that junction, even if the target folder has more permissive ACLs The permissions make it interesting, as symlinks can allow legacy applications to access configuration files in UAC-restricted areas (such as %ProgramFiles%) without changing existing access permissions, by storing the files in a non-restricted location and creating symlinks in the restricted directory.

• I have a password protected USB drive with hidden partition, how to convert to normal USB drive?

  - by deddebme

  I have a generic USB drive which has password protection, and I want to stop this password protection mechanism and to use it as a normal 8GB USB drive. I received this USB drive as a gift in Hong Kong, and there was no instruction menu whatsoever, not even the manufacturer name. When I plug the drive in Windows XP, the removable drive comes up as a read only 5.28MB partition with two files. When I try to add or remove any files or formatting it, it will says the drive is write protected. After launching the Login.exe and typed in the password, a 8GB read/writeable partition will be shown, and I'm free to do anything to it. But once after the drive is unplugged and replugged, the same read only partition will still comes out no matter what I did to the hidden partition. Anyone knows about this kind if USB drive? What did the manufacturer do to hide the partition? Is there a way to "low-level" formatting this drive to convert (or revert) it to a normal drive? Before typing in the password: After typing in the password:

• Load balancing with puppet

  - by Gonçalo Queirós

  Hi there. Im trying to setup a loadbalancing system. My load balancer (nginx) has a conf file where i should list all IP's of the upstream servers. I could put the IP's on the conf manually, but this ways i would need to change the conf file every time i add/remove an upstream server. For now i came up with two different ideas, but i don't like much of neither: 1 - Have every upstream machine to use Exported Resources to create a file with it's IP..Then the load balancer server will have an "include conf_directory/*", and load all the files created by the upstrem servers. Since the load balancer is using nginx this can be done, but if i wan't latter on to configure something that doesn't have the "include" on the conf files, this solution will not work. 2 - If the config doesn't support the "include" command, then we could have again, every upstream server use the Exported Resources to create a filw with its IP, and latter on, the load balancer execute a command that would pick every file and generate the config Both versions addopt the same techinque, the difference is that version 2 is used when the server (that needs to have a conf generated) doesn't recognize a command like "include" inside its own conf. Now, my question is, is there any way to do this in a different form? I suspect that there is, since puppet is made to manage multiple servers, it seems a bit strange not have a easy way to configure load balancers.

• how do you view / access the contents of a mounted dmg drive through TERMINAL hdiutil diskmount

  - by A. O.

  My external USB drive failed. I made a .dmg image file of the drive using disk utility. Later I was not able to mount the .dmg image. I used terminal hdiutil attach -noverify -nomount name.dmg diskutil list diskutil mountDisk /dev/disk4 then received the following message: Volume(s) mounted successfully However, I cant see the drive or access its contents through Finder. DUtility shows the drive as ghost but I still cant mount it using diskutility. Terminal tells me that the drive is mounted and constantly shows it in the diskutil list. pwd is not the mounted .dmg image. I dont know how to enter into the mounted image drive to see its contents. So in case what I said sounds like I see the files in the mounted image no this is not the case. I do not know how to access or even change the pwd within Terminal. I was hoping to see the mounted drive tru finder but I do not see that. So I need help as to how to find a way to access the mounted image drive if it was really mounted. Terminal says that it was and it shows it under diskutil list as a /dev/disk4. Can someone please help me access the files on this drive?

• Autounmounting USB keys with FAT filesystem on Linux (RHEL5)

  - by niXar

  For security reasons, I have two workstations i front of me, and I can only transfer data between them through a USB key. As you can imagine, it can get quickly tiresome, but the most annoying is having to unmount the things before removing them. Not umounting them results in missing files most of the time, even if I remove them a while after having last written to them. Now, since they're only used for transferring smallish files, and each are basically written once and read once, I don't need the fancy pansy caching infrastructure that makes clean unmounting a necessary step. And since the data is always a copy of something I have at hand, I don't care if the filesystem croaks from time to time. But anyway the system doesn't need to force that on me, it could simply make sure everything is committed with a second, and works synchronously. Then when I remove the key, nothing is lost. Is there a way to do this? I would appreciate any other tips on handling this situation. Edit: it appears the situation has changed between RHEL5 and Fedora up to F11 on one hand, and F12 on the other. The latter use DeviceKit-disk, and I haven't quite figured out how to do this. The method provided below in gconf does not work anymore.

• Tools required for a Web Development Project..

  - by RBA

  Hi, I wanted to design a project in linux which could contain programming languages(C, perl, PHP, HTML, XML etc) basically a web based project. Why i have chosen to build on Linux is because it is Open Source, and lot many things can be automated through scripting languages, which in windows i don't know. So, i have installed linux on a virtual machine(Host-Windows 2007 & Guest Linux CentOS), CentOS(command line interface). Since i am a beginner, so I want to know what all tools can be used to facilitate and ease my development process.

• processes slow after some time of actively running

  - by Yervand Aghababyan

  i have several cron jobs running on an ubuntu machine. each one does some pretty heavy load stuff. The cron jobs are parsing files and the bigger the file the longer it takes them to parse it. The strange thing is that if i make the files too big ( like 30mb) the script kind of hangs. It starts processing them really enthusiastically but after some time (something like 5-10 minutes) the cpu usage of the process drops a lot and it gets into some "zombie" state. If prior to this the process in htop was using 70-80% of the CPU then after this drop occurs it slows down to something like 5-10%. the load average drops down as well. The status of the processes sometimes changes to D in htop, which AFAIR stands for zombie. Today i noticed the same behavior of processes of mysql when executing heavy queries (a query took something like 4 hours to execute). the cron jobs are mostly php and during their processing most of the CPU eats the php process and not mysql. so i think the issue is not with a specific language/program but with the way the processes are "managed". The only other place i've seen similar behavior was on my Amazon EC2 micro instance when after some aggressive use of CPU the CPU quota was taking effect and everything was slowing down dramatically. This is a dedicated machine running ubuntu. what may be the cause?

• BSOD error 0x0000006B PROCESS1_INITIALIZATION_FAILED on boot

  - by DontCare4Free

  I reinstalled League of Legends because the patcher always gave me an error. However, out of complete stupidness I didn't uninstall the old installation first because I thought that it would simply replace the files. However, when the installer bar got to 100% it simply minimized. Then I closed the application from the task manager. I tried uninstalling it after a failed attempt to start it up. The same behavior as when I installed it. Then I tried reinstalling where it simply presented the InstallShield Modify/Repair/Remove menu and I selected repair. Nothing happened. Then I tried selecting Modify, then seeing that the only option (called DefaultFeature) was unchecked. Same behaviour as install/uninstall. After seeing that it still failed, I uninstalled again. And after that I deleted C:\Program Files (x86)\League of Legends manually. When I tried installing LoL again it still thought I had it, so I chose repair. This time something actually happened, but it installed the whole game to C:\Windows. Seeing what was going on I clicked cancel and then started it up to try uninstalling it. However, I got an error message about something not being registered and then the minimization to I decided to let it repair completely. Then I uninstalled it and it gave only the minimization. However, when I rebooted another application started up complaining about some library being absent. So I decided to do a system restore. After letting it complete I got a BSOD every time I tried starting up Windows normally or in safe mode. However, system recovery mode works, although the system recovery automatic repair does not fix it. After a bit of searching I found a Microsoft KB article about it (981833) and tried following the workaround instructions. Nothing happened. I am using Windows 7 Home Premium 64-bit and Ubuntu 10.04 LTS 64-bit installed with WUBI.

• User permissions linux. (proftpd / nginx)

  - by user55745

  I've been having a complete nightmare trying to configure proftpd. I've got proftp server working with an sql database. However I want to have any files uploaded able to viewed by the webserver running on the same box. The folders get created in /var/tmp/ as rwx------ 2 ftpuser ftpgroup 4096 Oct 8 20:35 50730c4346512 drwx------ 2 ftpuser ftpgroup 4096 Oct 8 20:38 50730f3a811ca I've tried adding www-data to group with the following usermod -g www-data ftpuser But this doesn't allow the web server access. In proftpd.conf I have the following umask set Umask 0022 It doesn't seem to make a difference what I set that value to. /etc/group (sure I've messed up one of these two but I'm getting desperate) ftpgroup:x:2001:www-data www-data:x:33:ftpgroup /etc/passwd www-data:x:33:33:www-data:/var/www:/bin/sh proftpd:x:108:65534::/var/run/proftpd:/bin/false ftp:x:109:65534::/srv/ftp:/bin/false ftpuser:x:2001:33:proftpd user www-data:/bin/null:/bin/false The ftpuser table in the database has uid / gid set to 2oo1 for both. I'm going absolutely crazy trying to solve this any help would be greatly appreciated. p.s Also, although if I manually connect to the ftp server I can upload files via FileZilla. Although this isn't working for the web-camera, although there is talky talky going on between the server and the camera.
