  • tightvnc authentication failure

    - by broiyan
    When I run a tightvnc client to establish a VNC session I sometimes receive an error message that suggests there are repeated failed VNC login attempts or a brute force attack. The message dialog title is "unsupported security type" and the text content is "too many authentication failures, try another connection? yes/no". This problem goes away if I reboot the Ubuntu server and reload the VNC server program and try again. From that point, it will work for multiple VNC sessions. My VNC sessions are typically about 20 minutes. At some time in the future, the problem may recur so it seems correlated to the time the server has been up or the time tightvnc has been loaded. Typically it takes only a day or so before the problem comes back. I am using tightvnc 1.3 on an server running Ubuntu 12.04. The version of vncserver is rather dated because that seems to be all that is available from tightvnc for linux servers. On the client side I use the newest Java-based VNC client (version 2.5) for both Windows access and Ubuntu access. All my VNC sessions are via SSH. I am the only user and I will typically use only the same client computer. How can I stop this problem from recurring? Edit I found the log file. This is a small excerpt of what I am seeing. Essentially, various IPs, not my own, are attempting to connect. What is the practical solution for this? 05/06/12 20:07:32 Got connection from client 69.194.204.90 05/06/12 20:07:32 Non-standard protocol version 3.4, using 3.3 instead 05/06/12 20:07:32 Too many authentication failures - client rejected 05/06/12 20:07:32 Client 69.194.204.90 gone 05/06/12 20:07:32 Statistics: 05/06/12 20:07:32 framebuffer updates 0, rectangles 0, bytes 0 05/06/12 20:24:56 Got connection from client 79.161.16.40 05/06/12 20:24:56 Non-standard protocol version 3.4, using 3.3 instead 05/06/12 20:24:56 Too many authentication failures - client rejected 05/06/12 20:24:56 Client 79.161.16.40 gone 05/06/12 20:24:56 Statistics: 05/06/12 20:24:56 framebuffer updates 0, rectangles 0, bytes 0 05/06/12 20:29:27 Got connection from client 109.230.246.54 05/06/12 20:29:27 Non-standard protocol version 3.4, using 3.3 instead 05/06/12 20:29:28 rfbVncAuthProcessResponse: authentication failed from 109.230.246.54 05/06/12 20:29:28 Client 109.230.246.54 gone 05/06/12 20:29:28 Statistics: 05/06/12 20:29:28 framebuffer updates 0, rectangles 0, bytes 0

  • People's experience of Cloud Computing (using Force.com)

    - by Digger
    I would like to know about people's experience of working with APEX and the SalesForce.com platform, was it easy to work with? How similar to Java and C# is it? What did you like? What don't you like? Would you recommend it? Do you think cloud computing has a long term successful future? My reason for asking is that I am currently looking at a new position which involves working with APEX on the SalesForce.com platform. The position interests me but I just want to try and understand what I might be signing up for with regards the languages/platform as it is completely different from what I have worked with before. I have seen lots of videos/blog posts online (mainly from the recent Dreamforce event) and they obviously are very positive but I was just after some experiences from developers, both positive and negative. I find cloud computing a very interesting idea, but I am very new to the subject. The position I am looking at offers a fantastic opportunity but I was just after some opinions on APEX and the platform as I have no real world experience just what I have seen from the online videos. I guess ultimately what I am asking is: Are APEX and the SalesForce.com platform good to get involved in? Is development on the Force.com just a "career dead end"? Is cloud computing just a fad? Or does it have a long term future? Apologies in advance if this is the wrong place to ask such a question. Thanks

  • Does Agile force developers to work more?

    - by Shooshpanchick
    Looking at common Agile practices it seems to me that they (intentionally or unintentionally?) force developer to spend more time actually working as opposed to reading blogs/articles, chatting, coffee breaks and just plain procrastinating. In particular: 1) Pair programming - the biggest work-forcer, just because it is inconvenient to do all that procrastination when there are two of you sitting together. 2) Short stories - when you have a HUGE chunk of work that must be done in e.g. a month, it is pretty common to slack off in the first three weeks and switch to OMG DEADLINE mode for the last one. And with the little chunks (that must be done in a day or less) it is exact opposite - you feel that time is tight, there is no space for maneuvering, and you will be held accountable for the task pretty soon, so you start working immediately. 3) Team communication and cohesion - when you underperform in a slow, distanced and silent environment it may feel ok, but when at the end of the day at Scrum meeting everyone boasts what they have accomplished and you have nothing to say you may actually feel ashamed. 4) Testing and feedback - again, it prevents you from keeping tasks "99% ready" (when it's actually around 20%) until the deadline suddenly happens. Do you feel that under Agile you work more than under "conventional" methodologies? Is this pressure compensated by the more comfortable environment and by the feeling of actually getting right things done quickly?

  • c++ How to use angular velocity that derived from inertia and force(torque) in 3d

    - by user1217203
    I am relatively new to game development. May my terminology and description are not appropriate. Please excuse my poor phrasing and help me by giving advice on how to question better if this question seems less fitting. I really appreciate your efforts. Hi. I am having hard time interpreting the set of values I have. I have inertia and force(torque) in terms of x y z. FYI I used x and y coordinates as my ground, flat coordinates and z as my up/down. I am assuming that since f = ma, that angular acceleration must be a = f / m. So I divide my torque by inertia. Then I add those x y z values to my angular velocity variable's x y z. However these x y z values confuse me. Don't I need angle/sec or radian/sec sort of values in order to apply rotation? The x y z values I have seemed to not say anything about radians or angular movement. Question : If I have ( 1, 2, 3 ) or any ( x, y, z ) as my angular velocity, how do I actually apply it as angular movement? FYI Here I am pasting my code : float mass = 100; float devidedMass = 1.0/12 * mass; Vec3 innertia( devidedMass* (_box._size.z*_box._size.z + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.z*_box._size.z )); box._angAccel += forceAng/innertia; box._angVelo += box._angAccel; box._angAccel.allZero(); source of my inertia calculation http://www.health.uottawa.ca/biomech/courses/apa4311/solids.pdf

  • Force startx to run X in a specific resolution and refresh Rate

    - by Z9iT
    From my past experience (using Win-Xp), this particular monitor works only on 60Hz , Best resolution being 1024x768. I have "installed and configured" Ubuntu 12.04 Minimal (on USB stick) so that most of the time terminal is used, however, whenever there is a need to enter GUI, I may issue startx command to go into gnome. However the problem is that on this particular system, issuing this command poses problem because its default refresh rate won't synchronize with the monitor. The display keep on flickering and utterly unreadable. It is visible that gnome has been loaded and default wallpaper and desktop items are visible. But the problem is due to refresh rate different than 60Hz. I am looking for a command attribute to startx command which will force the refresh rate to 60Hz and resolution preferably to 1204x768 I can open terminals with Ctrl+Alt+T and enter commands. Key combinations like Ctrl+Alt+NumPlus works flawlessly in distributions like solaris, but it's not working for me. Also the commands like xrandr -r 60 60 being refresh rate wont work. The same problem is faced even when I boot from a live CD

  • How to force ADF to speak your language (or any common language)

    - by Blueberry Coder
    When I started working for Oracle, one of the first tasks I was given was to contribute some content to a great ADF course Frank and Chris are building. Among other things, they asked me to work on a module about Internationalization. While doing research work, I unearthed a little gem I had overlooked all those years. JDeveloper, as you may know, speaks your language - as long as your language is English, that is. Oracle ADF, on the other hand, is a citizen of the world. It is available in more than 25 different languages. But while this is a wonderful feature for end users, it is rather cumbersome for developers. Why is that? Have you ever tried to search the OTN forums for a solution with a non-English error message as your query? I have, once. But how can you force ADF to use English for its logging operations? Playing with your system settings will not help, unfortunately. By default, ADF will output its error messages in the selected locale for the operating system account the application server runs on. The only way to change this behavior is to pass initialization parameters to the JVM used by the application server. It is even possible to specify the language and country/region separately. In the example below, we choose English and the United States respectively. -Duser.language=en -Duser.country=US In the case of WebLogic Server, it is possible to add such parameters in setDomainEnv.sh (or .cmd) to apply the settings to all the managed servers present on a node. In the coming weeks, I will write a few posts about other internationalization issues. Is there anything you would like me to cover? Let me know in the comments.

  • How to force a clock update using ntp?

    - by ysap
    I am running Ubuntu on an ARM based embedded system that lacks a battery backed RTC. The wake-up time is somewhere during 1970. Thus, I use the NTP service to update the time to the current time. I added the following line to /etc/rc.local file: sudo ntpdate -s time.nist.gov However, after startup, it still takes a couple of minutes until the time is updated, during which period I cannot work effectively with tar and make. How can I force a clock update at any given time? UPDATE 1: The following (thanks to Eric and Stephan) works fine from command line, but fails to update the clock when put in /etc/rc.local: $ date ; sudo service ntp stop ; sudo ntpdate -s time.nist.gov ; sudo service ntp start ; date Thu Jan 1 00:00:58 UTC 1970 * Stopping NTP server ntpd [ OK ] * Starting NTP server [ OK ] Thu Feb 14 18:52:21 UTC 2013 What am I doing wrong? UPDATE 2: I tried following the few suggestions that came in response to the 1st update, but nothing seems to actually do the job as required. Here's what I tried: Replace the server to us.pool.ntp.org Use explicit paths to the programs Remove the ntp service altogether and leave just sudo ntpdate ... in rc.local Remove the sudo from the above command in rc.local Using the above, the machine still starts at 1970. However, when doing this from command line once logged in (via ssh), the clock gets updated as soon as I invoke ntpdate. Last thing I did was to remove that from rc.local and place a call to ntpdate in my .bashrc file. This does update the clock as expected, and I get the true current time once the command prompt is available. However, this means that if the machine is turned on and no user is logged in, then the time never gets updates. I can, of course, reinstall the ntp service so at least the clock is updated within a few minutes from startup, but then we're back at square 1. So, is there a reason why placing the ntpdate command in rc.local does not perform the required task, while doing so in .bashrc works fine?

  • Android - Force Close - Null Pointer on Canvas?

    - by user22241
    Please bear with me. I have a very odd problem. Basically, my app so far, has 3 activities (a main splash screen, an 'options/menu' screen and the main app). If I follow the very specific steps oulined below, I get a 'null pointer exception' in the 2nd activity) and the app force closes...... Here are the steps: Start the app (a game based on Surfaceview), tap through to the third activity so the game is running, then hit the home key so the game is paused and put to the background, the activity/app is ended through DDMS in the SDK then restarted on the device (all OK so far), now if I hit the back key on the device twice in quick succession, it happens. All other sequence of events is fine, even to the point of pressing the back key, waiting for the previous activity to show, then hitting back again - all OK. Only when the back key is pressed twice in quick succession following all the above steps does the problem occur. I'm assuming that the canvas isn't ready as it's showing as 'null' when this happens, but I'm not sure why this is happening as surely it's happening when I'm trying to go back to activity 1, but the logcat shows the error in activity 2. if I stop the activity running my 'doDraw' method (which referenced the canvas), then all is OK - so I can safely assume it is the canvas causing the problem. Also, if I skip my first activity (which is a very basic full-screen button which just displays a splashscreen and waits for the user to tap the screen), and make my 2nd activity the launch activity, again, it is OK. this is the part of the code that I think is probably relevant: @Override public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) { vheight = this.getHeight(); vwidth = this.getWidth(); } @Override public void surfaceCreated(SurfaceHolder holder) { vheight = this.getHeight(); vwidth = this.getWidth(); this.viewWidth = vwidth; this.viewHeight = vheight; if (runthread==false){ if (preThread.getState()==Thread.State.TERMINATED){ preThread = new OptionsThread(thisholder, thiscontext, thishandler); } preThread.setRunning(true); preThread.start();} } @Override public void surfaceDestroyed(SurfaceHolder holder) { preThread.setRunning(false); //Stop the loop boolean retry = true; //Stop the thread while (retry) { try { preThread.join(); retry = false; } catch (InterruptedException e) { } } Thank you all for any help you can offer

  • samba 3.5 "force user" doesn't seem to be sticking

    - by myCubeIsMyCell
    After installing a new OS with newer version of samba, I'm having trouble accessing my shares. I can browse to the specific share, but only to the top level. As best I can tell from the logs, it seems the "force user" in the samba config isn't sticking beyond the initial connection. Details below. I installed a new version of CentOS on my storage server. My old CentOS (4?)install had samba version 3.0.33, new CentOS is using 3.5.10. No domain/AD involved ... just home workgroup. no real security... just some shares hidden & some defined as read-only. here's my config: [global] workgroup = WORKGROUP server string = Samba Server Version %v netbios name = luna security = share # logs split per machine log file = /var/log/samba/log.%m log level = 2 # max 50KB per log file, then rotate max log size = 50 winbind use default domain = Yes [strge] comment = please path = /storage browseable = yes read only = no force user = windowsguest force group = users guest ok = yes So... the problem I'm running into is that the 'force user' only seems to hold for the initial connection & I see all the top level folders fine. When I drill into a folder I get access denied - which appears to be due to my windows user info being sent (trys to authenticate xuser - a non-existant user to samba, so maps to nobody & fails). Here's the smb error msg: [2012/11/29 14:30:27.326195, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [xuser] -> [xuser] FAILED with error NT_STATUS_NO_SUCH_USER [2012/11/29 14:30:27.326251, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [nobody] -> [nobody] FAILED with error NT_STATUS_NO_SUCH_USER Most of the top level directories are 755, some 777. Either way, can not access them. If I do a chown -R windowsguest.users ... no change... but if I do a chmod -R to 777 or 755 they become browsable... but still can't create files (even for 777 ones). Not sure what role it plays if any... but had to recreate the user windowsguest under the new os install, uid & gid match old user. Seems the main issue as far as I can tell is that samba isn't maintaining the 'force user' - but I could be wildly off base. Client OS is win7 pro x64. Thanks for any suggestions or advice!

  • How to Force Graphics Options in PC Games with NVIDIA, AMD, or Intel Graphics

    - by Chris Hoffman
    PC games usually have built-in graphics options you can change. But you’re not limited to the options built into games — the graphics control panels bundled with graphics drivers allow you to tweak options from outside PC games. For example, these tools allow you to force-enabling antialiasing to make old games look better, even if they don’t normally support it. You can also reduce graphics quality to get more performance on slow hardware. If You Don’t See These Options If you don’t have the NVIDIA Control Panel, AMD Catalyst Control Center, or Intel Graphics and Media Control Panel installed, you may need to install the appropriate graphics driver package for your hardware from the hardware manufacturer’s website. The drivers provided via Windows Update don’t include additional software like the NVIDIA Control Panel or AMD Catalyst Control Center. Drivers provided via Windows Update are also more out of date. If you’re playing PC games, you’ll want to have the latest graphics drivers installed on your system. NVIDIA Control Panel The NVIDIA Control Panel allows you to change these options if your computer has NVIDIA graphics hardware. To launch it, right-click your desktop background and select NVIDIA Control Panel. You can also find this tool by performing a Start menu (or Start screen) search for NVIDIA Control Panel or by right-clicking the NVIDIA icon in your system tray and selecting Open NVIDIA Control Panel. To quickly set a system-wide preference, you could use the Adjust image settings with preview option. For example, if you have old hardware that struggles to play the games you want to play, you may want to select “Use my preference emphasizing” and move the slider all the way to “Performance.” This trades graphics quality for an increased frame rate. By default, the “Use the advanced 3D image settings” option is selected. You can select Manage 3D settings and change advanced settings for all programs on your computer or just for specific games. NVIDIA keeps a database of the optimal settings for various games, but you’re free to tweak individual settings here. Just mouse-over an option for an explanation of what it does. If you have a laptop with NVIDIA Optimus technology — that is, both NVIDIA and Intel graphics — this is the same place you can choose which applications will use the NVIDIA hardware and which will use the Intel hardware. AMD Catalyst Control Center AMD’s Catalyst Control Center allows you to change these options on AMD graphics hardware. To open it, right-click your desktop background and select Catalyst Control Center. You can also right-click the Catalyst icon in your system tray and select Catalyst Control Center or perform a Start menu (or Start screen) search for Catalyst Control Center. Click the Gaming category at the left side of the Catalyst Control Center window and select 3D Application Settings to access the graphics settings you can change. The System Settings tab allows you to configure these options globally, for all games. Mouse over any option to see an explanation of what it does. You can also set per-application 3D settings and tweak your settings on a per-game basis. Click the Add option and browse to a game’s .exe file to change its options. Intel Graphics and Media Control Panel Intel integrated graphics is nowhere near as powerful as dedicated graphics hardware from NVIDIA and AMD, but it’s improving and comes included with most computers. Intel doesn’t provide anywhere near as many options in its graphics control panel, but you can still tweak some common settings. To open the Intel graphics control panel, locate the Intel graphics icon in your system tray, right-click it, and select Graphics Properties. You can also right-click the desktop and select Graphics Properties. Select either Basic Mode or Advanced Mode. When the Intel Graphics and Media Control Panel appears, select the 3D option. You’ll be able to set your Performance or Quality setting by moving the slider around or click the Custom Settings check box and customize your Anisotropic Filtering and Vertical Sync preference. Different Intel graphics hardware may have different options here. We also wouldn’t be surprised to see more advanced options appear in the future if Intel is serious about competing in the PC graphics market, as they say they are. These options are primarily useful to PC gamers, so don’t worry about them — or bother downloading updated graphics drivers — if you’re not a PC gamer and don’t use any intensive 3D applications on your computer.

  • Properly force SSL with .htaccess, no double authentication

    - by cwd
    I'm trying to force SSL with .htaccess on a shared host. This means there I only have access to .htaccess and not the vhosts config. I know you can put a rule in the VirtualHost config file to force SSL which will be picked up there (and acted upon first), preventing double authentication, but I can't get to that. Here's the progress I've made: Config 1 This works pretty well but it does force double authentication if you visit http://site.com - once for http and then once for https. Once you are logged in, it automatically redirects http://site.com/page1.html to the https coutnerpart just fine: RewriteEngine On RewriteCond %{HTTPS} !=on RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] RewriteEngine on RewriteCond %{HTTP_HOST} !(^www\.site\.com*)$ RewriteRule (.*) https://www.site.com$1 [R=301,L] AuthName "Locked" AuthUserFile "/home/.htpasswd" AuthType Basic require valid-user Config 2 If I add this to the top of the file, it works a lot better in that it will switch to SSL before prompting for the password: SSLOptions +StrictRequire SSLRequireSSL SSLRequire %{HTTP_HOST} eq "site.com" ErrorDocument 403 https://site.com It's clever how it will use the SSLRequireSSL option and the ErrorDocument403 to redirect to the secure version of the site. My only complaint is that if you try and access http://site.com/page1.html it will redirect to https://site.com/ So it is forcing SSL without a double-login, but it is not properly forwarding non-SSL resources to their SSL counterparts. Regarding the first config, Insyte mentioned "using mod_rewrite to perform a simple redirect is a bit of overkill. Use the Redirect directive instead. It's possible this may even fix your problem, as I believe mod_rewrite rules are some of the last directives to be processed, just before the file is actually grabbed from the filesystem" I have not had no such luck on finding a force-ssl config option with the redirect directive and so have been unable to test this theory.

  • how to force an illegal netmask in ubuntu

    - by user1064232
    I want to force a netmask on my Ubuntu machine. For example, I want 11.0.0.1 to get a netmask of 255.255.255.0 I tried editing /etc/network/interfaces and I forced the desired netmask, but as soon as I restarted the interfaces it changed it back to the default value. When I used ifconfig the netmask that I gave survived the interface restart but it was reset as soon as I rebooted the machine. Is there a way to force an "illegal" netmask on an interface?

  • Force Pinned taskbar items to be "icon only" all the time in Windows 7

    - by Robert
    By default (at least in my installation), pinned items on the taskbar will be "icon only" when they have no active windows, but when there are active window, the icon expanded to include text (typically some portion of the title text). I'm looking for a way to either: A (preferred option): For any single pinned item, force this pinned item to always display as just the icon even if it has active windows. OR B (acceptable option): Force ALL pinned items to always display as icon only in the taskbar

    It writes this in logs: =INFO REPORT==== 2012-03-14 17:48:54 === I(<0.467.0>:ejabberd_listener:281) : (#Port<0.4384>) Accepted connection {{10,254,239,2},51986} -> {{10,254,239,1},5222} =INFO REPORT==== 2012-03-14 17:48:54 === I(<0.1308.0>:ejabberd_c2s:784) : ({socket_state,tls,{tlssock,#Port<0.4384>,#Port<0.4386>},<0.1307.0>}) Failed authentication for USERNAME =INFO REPORT==== 2012-03-14 17:48:54 === I(<0.1308.0>:ejabberd_c2s:649) : ({socket_state,tls,{tlssock,#Port<0.4384>,#Port<0.4386>},<0.1307.0>}) Failed authentication for USERNAME It doesn't write IP with a failure. And strings "Accepted connection" and "Failed auth.." may even not stand nearby (as I think on heavily loaded servers) to be able to use fail2ban. What to do? And how jabber servers (using ejabberd) are protected?

  • force recompilation of war file including its Jar dependencies

    - by Mik378
    I have a project A (a webapp), depending on project B (B.jar) and this one depending on project C (C.jar). I would like to create a maven goal named "Rebuild War", that clean all compiled code for these 3 projects and rebuild the whole in order to obtain a fresh War file. I tried mvn clean package on project A, but I noticed that B and C are not recompiled. Indeed, B.jar and C.jar that are contained in local repository don't have a changing creation date. Is there an adapted maven command for this requirement ?

  • DNS configuration to force root domain to www

    - by kolosy
    we have an app running on heroku. the dns setup is like this: A record for domain.com - heroku front end ip addresses CNAME for www.domain.com - specific host name for our app provided by heroku we also have an SSL cert for www.domain.com. the issue is that if someone goes to https://domain.com/secure_stuff, they will get heroku's SSL cert, instead of ours, causing lots of fear. We can do things on our end to make sure that all of our URLs point to https://www.domain.com, but it still won't solve this specific issue. is there a way to configure the DNS record to redirect all root domain traffic to the www subdomain?

  • Force apt to remove all emacs*

    - by wishi
    Hi! I have a bug-problem with the apt-packages of emacs: >>Error occurred processing debian-ispell.el: File error (("Opening input file" "no such file or directory" "/usr/share/emacs23/site-lisp/dictionaries-common/debian-ispell.el")) >>Error occurred processing ispell.el: File error (("Opening input file" "no such file or directory" "/usr/share/emacs23/site-lisp/dictionaries-common/ispell.el")) >>Error occurred processing flyspell.el: File error (("Opening input file" "no such file or directory" "/usr/share/emacs23/site-lisp/dictionaries-common/flyspell.el")) emacs-install: /usr/lib/emacsen-common/packages/install/dictionaries-common emacs23 failed at /usr/lib/emacsen-common/emacs-install line 28, <TSORT> line 30. dpkg: error processing emacs23-lucid (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of emacs: emacs depends on emacs23 | emacs23-lucid | emacs23-nox; however: Package emacs23 is not installed. Package emacs23-lucid which provides emacs23 is not configured yet. Package emacs23-nox which provides emacs23 is not installed. Package emacs23-lucid is not configured yet. Package emacs23-nox is not installed. dpkg: error processing emacs (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure. Errors were encountered while processing: emacs23-lucid emacs E: Sub-process /usr/bin/dpkg returned an error code (1) In fact I would be satisfied with just emacs23-nox, a couple of plugins - from apt. But I can neither --purge nor --purge reinstall, nor remove the packages. It always processes until this certain bug. I did some google-searching, found some stuff on Launchpad suggesting: sudo apt-get install --reinstall --purge emacsen-common But this is the same... so I hope there a way to tell app to just remove everything releated to emacs, and to start from scratch again? Thanks, Marius
