• Citrix Error: Your user profile was not loaded correctly

  - by George

  We get this error from out citrix server: Your user profile was not loaded correctly! You have been logged on with a temporary profile. Changes you make to this profile will be lost when you log off. Please see the event log for details or contact your administrator. I am well aware there is a workaround by Citrix, that can be found here, but that doesn't permanently fix our issue. It seems to come back. Any idea why that happens? Any suggestions on how to fix it? Citrix version is 4.5 running on Windows 2003 x32 EDIT 14.IX.2012 @ 16.03 CT I am sorry, let me clarify, it happens to some users, not all and not all the time.

• What is the best way to implement collision detection using Bullet physics engine and a track generated from a curve?

  - by tigrou

  I am developing a small racing game were the track is generated from a curve. As said above, the track is generated, but not infinite. The track of one level could fit with no problem in memory and will contain a reasonably small amount of triangles. For collisions, I would like to use Bullet physics engine and know what is the best way to handle collisions with the track efficiently. NOTE : The track will be stored as a static rigid body (mass = 0). The player will be represented by a sphere shape for collisions. Here is some possibilities i have in mind : Create one rigid body, then, put all triangles of the track (except non collidable stuff) into it. Result : 1 body with many triangles (eg : 30000 triangles) Split the track into several sections (eg: 10 sections). Then, for each section, create a rigid body and put corresponding triangles in it. Result : small amount of bodies with relatively small amount of triangles (eg : 1500 triangles per section). Split the track into many sub-sections (eg : 1200 sections). Here one subsection = very small step when generating the curve. Again for each sub-section, create a body and put triangles in it. Result : many bodies with very small amount of triangles (eg : 20 triangles). Advantage : it could be possible to "extra data" to each of the subsection, that could be used when handling collisions. Same as 2, but only put sections N and N+1 in physics engine (where N = current section where the player is). When player reach section N+1, unload section N and load section N+2 and so on... Issue : harder to implement, problems if the player suddenly "jump" from one section to another (eg : player fly away from section N, and fall on section N + 4 that was underneath : no collision handled, player will fall into void ) Same as 4, but with many sub-sections. Issues : since subsections are very small there will be constantly new bodies added and removed to physics engine at runtime. Possibilities for player to accidently skip some sections and fall into the void are higher than 4.

• Win2008 - restrict VPN user permissions

  - by Sebas

  Windows 2008 R2 SP1 Foundations file server with no AD, only workgroup sharing some folders, and now a RRAS server. Shared folders are open to everyone in the office (XPs and Sevens) without accounts/passwords, but I was thinking about partially limiting access to the new "VPNuser" account. I'm new to Windows Server and its permissions settings: I thought about denying access to vpnuser through NTFS rights in some folders. It doesn't work, but now I'm guessing that the vpnuser is not considered as a logged user (doesn't appear as such) and is considered a "guest", like the rest of people connecting in the office. I say that because of this: http://social.technet.microsoft.com/Forums/windowsserver/en-US/ff6d3726-ff41-4d3f-9d97-5361af0206dd/vpn-users-on-server-shows-as-guest?forum=winserverNIS Also, because when I create a txt file using the VPN connection, owner field shows in description as "guest". Am I right? How can I set different rights for the VPNuser from the rest of "guest" users in the office?

• Tool/Program/Script/Formula for deciphering Active Directory Connection Strings for 3rd party user i

  - by I.T. Support

  We're using WSFTP, which has an Active Directory Integration module. To populate the user accounts you need to provide a connection string akin to: OU=Users,DC=domain,DC=com CN=Domain Users,OU=Users,DC=domain,DC=com Questions: Is there a Tool/Program/Script/Formula that allows me to decipher how these strings might look based on what I can see in Active Directory Users & Computers? Is there a proper/accepted name for these types of connection strings? I don't even know what to Google to get more information about how to format one properly How would I troubleshoot the connection string if I think it looks correctly formatted, but it isn't working? Thanks!

• Vmware server: Browser does not load user interface

  - by matnagel

  I have the latest vmware server isntalled on ubuntu 8.04 lts 64 bit. I access the user interface over this url, which matches my ip and port settings: https://10.1.1.99:11222/ui Sometimes it works in fierofox 3.6, but sometimes not. Same in Google Chrome. When it does not work, what happens is that the cert is checked, the browser is loading something, but the result is a white page. Sometimes the favicon of vmware (blue with 3 squares) appears, but only the white page. And sometimes it works. I reload many times, most of the time the whit epage appears again. On some days I succeed. But on many days not. I can give more info if someone tells me what is needed. Please help, we need this badly.

• Monitoring User Login time

  - by beakersoft

  Hi, i have recently been given the task of trying to work out why the login time (not machine boot time) for some of our users seems slow. The vast majority of clients (95%) are running on XP sp3, Windows 2003 domain controlers. Most users have the same model of machine. I would like to be able to see how long each of the polices are taking to load (if possable split user and computer) and any other info that might help (services starting etc) I changed the userenvdebuglevel reg option to generate the userenv.log file but it did'nt contain very much info Thanks Luke

• knife azure image list doesn't return User image

  - by TooLSHeD

  I'm trying to create and bootstrap a Windows VM in Azure using knife-azure. I initially tried using a Public Win 2008 r2 image, but quickly found out that winrm needs to be configured before this can work. So, I created a VM from that image, configured winrm as per these instructions and captured the VM. The problem is that the image does not show up when executing knife azure image list. When I try creating the server with the image name from the Azure portal, it complains that it does not exist. I'm running Ubuntu, so I tried the Azure cli tools and it doesn't show there either. I installed Azure PS in a Win 8 VM and then it shows up. Feeling encouraged, I installed Chef and knife-azure in the Win 8 VM, but it doesn't show up there either. How do I get my User image to show in knife azure?

• Getting link to abstract indexed in Google Scholar

  - by JordanReiter

  We have a large digital library with thousands of papers indexed in Google Scholar. We allow Google Scholar to index our PDFs but they're blocked unless you have a subscription. So Google has full-text indexing/searching of our PDFs (great!) but then the links point just to those PDFs (boo!) instead of the more helpful abstract pages. Does anyone know what could cause an issue like this? I am, to the best of my knowledge, following all of the guidelines laid out in their Inclusion Guidelines. Here's some example meta data: <meta name="citation_title" content="Sample Title"/> <meta name="citation_author" content="LastName, FirstName"/> <meta name="citation_publication_date" content="2012/06/26"/> <meta name="citation_volume" content="1"/> <meta name="citation_issue" content="1"/> <meta name="citation_firstpage" content="10"/> <meta name="citation_lastpage" content="20"/> <meta name="citation_conference_title" content="Name of the Conference"/> <meta name="citation_isbn" content="1-234567-89-X"/> <meta name="citation_pdf_url" content="http://www.example.org/p/1234/proceeding_1234.pdf"/> <meta name="citation_fulltext_html_url" content="http://www.example.org/f/1234/"/> <meta name="citation_abstract_html_url" content="http://www.example.org/p/1234/"/> <link rel="canonical" href="http://www.example.org/p/1234/" /> example.org/p/1234 is the abstract page for the article; example.org/f/1234 is the fulltext link accessible to subscribers only (and to Google Scholar). example.org/p/1234/proceeding_1234.pdf is the fulltext PDF link.

• VNC unattended Server (No user Interaction)

  - by Louis van Tonder

  I worked on a proof on concept a while ago.... whereby I managed to get VNC going in full "unattended" mode... I.e. The VNC Server dials into the viewer... which is running in Listening mode. The same concept of how single click works, but without the user interaction. I cant seem to locate my source files for this concept I worked on... although I have found my shortcut that worked on the Viewer side to listen. "C:\Program Files\UltraVNC\vncviewer.exe" -listen 5007 /noauto /256colors I can not however remember/locate my demo of what the server is doing.... how to configure it. If I remember correctly, the server was also started with command line params that "dialed" into a remote IP/port, that the viewer is listening on. Any ideas? Thanks

• Lost Root and other user passwords

  - by Webnet

  This isn't a huge deal, because there's very little on the server (literally a file or two) that we actually need off of it. But we disabled root logins as a security measure and can't remember any of our other user passwords. I'm assuming that there's nothing we can do at this point to get into the server? I'm sitting next to the box... Update Oops... actually, I need to export an SVN off of this server. So yeah, there's stuff I need.

• How to package static content outside of web application?

  - by chinto

  Our web application has static content packaged as part of WAR. We have been planning to move it out of the project and host it directly on Apache to achieve the following objectives. It's getting too big and bloating the EAR size resulting in slower deployment across nodes. Faster deployment times. Take the load of Application Server Host the static content on a sub domain allowing some browsers (IE) to load resources simultaneously Give us an option to use further caching such as Apache mod_cache apart from the cache headers we send out to browsers. We use yuicompressor-maven-plugin to aggregate and minimize JS file. My question is how do package and manage this static content out side of the web application? My current options are. New maven war project. Still use the same plugin for aggregation and compression. Just a plain directory in SVN and use YUI/Google compressor directly. Or is there a better technology out there to manage static content as a project?

• How to whitelist a user agent for nginx?

  - by djb

  I'm trying to figure out how to whitelist a user agent from my nginx conf. All other agents should be shown a password prompt. In my naivity, I tried to put the following in before deny all: if ($http_user_agent ~* SpecialAgent ) { allow; } but I'm told "allow" directive is not allowed here (!). How can I make it work? A chunk of my config file: server { server_name site.com; root /var/www/site; auth_basic "Restricted"; auth_basic_user_file /usr/local/nginx/conf/htpasswd; allow 123.456.789.123; deny all; satisfy any; #other stuff... } Thanks for any help.

• "Unknown user name or bad password" when I launch ADUC

  - by Chris

  When I open up Active Directory Users and Computers from my workstation, I receive an error: Naming information cannot be located because: Logon failure: unknown user name or bad password. Contact your system administrator to verify that your domain is properly configured and is currently online. If I log in to my workstation as somebody else, it works. If I log into a different workstation using my account, it works. All the workstations in question are running Windows Vista (32 and 64 bit) or Windows Server 2008. The domain controller in question is running Windows Small Business Server 2008. Everything else (that I tried) in the Remote Server Administration Tools runs just fine. Any thoughts? Edit: I just tried reinstalling RSAT. No such luck.

• Spam mail through SMTP and user spoofing

  - by Josten Moore

  I have noticed that it's possible to telnet into a mailserver that I own and send spoofed messages to other clients. This only works for the domain that the mail server is regarding; I cannot do it for other domains. For example; lets say that I own example.com. If I telnet example.com 25 I can successfully send a message to another user without authentication: HELO local MAIL FROM: [email protected] RCPT TO: [email protected] DATA SUBJECT: Whatever this is spam Spam spam spam . I consider this a big problem; how do I secure this?

• Apollo linux boot into single user

  - by Spirit

  We have a device that runs Appolo Linux and I have to boot that device into a single user mode so that i can run a fsck to check the hard drive for errors. I've been goggling this during the past hour and so far I haven't found any specific method on how can I do that on this version on Linux. The device is known formerly as a NFX Cinxi One - now re-branded into BlackStratus LOG Storm. If any of you have any experience with this one you may know it is a device that is used to collect logs from other servers. I know that the above info isn't much but that is everything that I can provide up until now since tomorrow I have to follow up closely on this problem.

• 404 code/header for search engines, on removed user content?

  - by mowgli

  I just got an email, from a former user on my website He was complaining that Google still shows the contact page he created on my site, even though he deleted it a month ago This is the first time in many years anyone requests this I told him, that it's almost entirely up to Google what content it wants to keep/show and for how long. If it's deleted on the site, I can't do much, other than request a re-visit from the googlebot The user-page already now says something like "Not found. The user has removed the content" TL;DR: But the question is: Should I generally add a 404 header (or other) for dynamic user content that has been removed from the site? Or could this hurt the site (SEO)?

• 'Singleton' application - or let the user only launch one instance of a program at the time

  - by Disco

  I'm running a few linux desktops; mainly for kids (yeah, trying to teach them the right OS at early stage) (running Ubuntu 10.10, Gnome) The problem is that they found very funny to make their workstations (actually, old 512 Mb pentium 4) by launching thousands of firefox instances. I'm looking for a way to restrict them to launch 'N' instances of a particular application. Haven't figured yet how. Thought of a monitoring daemon but I think that would be too ressources hungry. Any idea of a script/trick to achieve this ? Note: i might have 1-2 level of users (the kids, and the more grown up kids) so i have also to limit per user; something like user1: 3firefox, user2: 2firefox instances.

• nginx caching per user agent

  - by Tuinslak

  I'm currently using nginx as reverse proxy with caching enabled. However, the main site has two different layouts, depending on the user-agent (mobile or not). I've tried something similar to this: # mobile users if ($http_user_agent ~* '(iPhone|iPod|mobile|Android|2.0\ MMP|240x320|AvantGo|BlackBerry|Blazer|Cellphone|Danger|DoCoMo|Elaine/3.0|EudoraWeb|hiptop|IEMobile)') { set $iphone_request '1'; } if ($iphone_request = '1') { proxy_cache mobile; } if ($iphone_request = '') { proxy_cache site; } proxy_cache_key "$scheme://$host$request_uri"; proxy_pass http://real-site.tld; However, nginx gives an error, stating proxy_cache can't be used in an if-structure. Any other way to serve from a different cache depending on the browser? Thanks, Tuinslak

• Log with iptalbes which user is delivering email to port 25

  - by Maus

  Because we got blacklisted on CBL I set up the following firewall rules with iptables: #!/bin/bash iptables -A OUTPUT -d 127.0.0.1 -p tcp -m tcp --dport 25 -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --gid-owner mail -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner root -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner Debian-exim -j ACCEPT iptables -A OUTPUT -p tcp -m limit --limit 15/minute -m tcp --dport 25 -j LOG --log-prefix "LOCAL_DROPPED_SPAM" iptables -A OUTPUT -p tcp -m tcp --dport 25 -j REJECT --reject-with icmp-port-unreachable I'm not able to connect to port 25 from localhost with another user than root or a mail group member - So it seems to work. Still some questions remain: How effective do you rate this rule-set to prevent spam coming from bad PHP-Scripts hosted on the server? Is there a way to block port 25 and 587 within the same statement? Is the usage of /usr/sbin/sendmail also limited or blocked by this rule-set? Is there a way to log the username of all other attempts which try to deliver stuff to port 25?

• Active Directory management with low user rights

  - by DemonWareXT

  Our problem: The client, a normal user, has to be able to reset multiple passwords at once. Around 30 in one go. This would call for powershell or something along these lines, but for AD and Powershell one needs to be domain administrator. My solution would be to make a service that runs on the AD server and take connections from a program. The service would then do the AD changes. So far so good, I would just like to hear some other thoughts on this problem. Because I sure can't be the only one with it

• Verifying that a user comes from a 'partner' site?

  - by matt_tm

  We're building a Drupal module that is going to be given to trusted 'corporate partners'. When a user clicks on a link, he should be redirected to our site as if he's a logged in user. How should I verify that the user is indeed coming from that site? It does not look like 'HTTP_REFERER' is enough because it appears it can be faked. We are providing these partner sites with API Keys. If I receive the API-key as a POST value, sent over https, would that be a sufficient indicator that the user is a genuine partner-site user?

• How can I restrict the backuppc client user as much as possible? (rsync)

  - by jxn

  I have backuppc making full backups of servers, but I'd like to be sure that my set up is as paranoid as possible. BackupPC is set up to backup via rsync, and it is set up to use a specific user on each client to be backed up. Because the backuppc client user has to have access to every file on the client machine and the ability to ssh into the machine without an interactive password, I'm a little nervous about securing the clients, and I'd like to know I haven't overlooked any options. Here's what I have in place: in the client user's authorized_keys file, i've included from="IPTOSERVER",command="/usr/bin/rsync" before the user's public key, so that the user can only login coming from the BackupPC server. Next, in the sudoers file, I've added this line: backuppc ALL=NOPASSWD: /usr/bin/rsync to allow root-level permissions only for the rsync command for that user. Are there other user, policy, or ssh restrictions that I can add while still allowing the backup pc client user to rsync all files?

• user related commands hang on open("/etc/localtime", O_RDONLY) = 4 in CentOS 5.5

  - by fuzzy lollipop

  I am logged in as root when doing a strace -etrace=open adduser git it hangs on open("/etc/localtime", O_RDONLY) = 4 for like 2 minutes then continues on. Also when I try and strace -etrace=open su git it just hangs at the same place as well, I can't login via ssh as the git user either. Some other users I created work just fine, like su tomcat and I can ssh in as tomcat as well. I deleted the file that was at /etc/localtime and replaced it with a symlink to ln -s /usr/share/zoneinfo/US/Eastern /etc/localtime and it didn't change the behavior in any way.

• Tool to test a user account and password (test login)

  - by TheCleaner

  Yeah, I can fire up a VM or remote into something and try the password...I know...but is there a tool or script that will simulate a login just enough to confirm or deny that the password is correct? Scenario: A server service account's password is "forgotten"...but we think we know what it is. I'd like to pass the credentials to something and have it kick back with "correct password" or "incorrect password". I even thought about a drive mapping script with that user account and password being passed to see if it mapped the drive successfully or not but got lost in the logic of making it work correctly...something like: -Script asks for username via msgbox -script asks for password via msgbox -script tries to map a drive to a common share that everyone has access to -script unmaps drive if successful -script returns popup msgbox stating "Correct Password" or else "Incorrect Password" Any help is appreciated...you'd think this would be a rare occurrence not requiring a tool to support it but...well....
