• How to properly uninstall/reinstall Ubuntu One on Windows XP?

  - by user73303

  I had previously installed an Ubuntu One client as a test on a Windows XP machine. Now I wanted to change the account for the client to a production one but had problems changing the email address so decided to do a reinstall. Ran uninstall. Downloaded ubuntuone-3.0.2-windows-installer.exe. It downloads, goes through the unpacking/install – strangely some of the messages say updating as if it was replacing something that was already there. I do not get the setup/signin screen. There is no ubuntu% processes running. The Program files/ubuntuone directory exists with data and dist folders. The U icon is on the desktop – pointing at ubuntuone/dist/ubuntuone-control-panel-qt.exe but this does not run. Ran uninstall again, deleted Program files/ubuntuone directory, removed any ubuntu entries for registry, rebooted. Downloaded install again - exactly the same as above. How can I uninstall Ubuntu One to get a clean reinstall? Or force the install to continue after downloading/unpacking?

• How can I unify my email, calendar and tasks (2 exchange accounts + 1 gmail)

  - by Assaf Stone

  This is my situation: I work as a consultant, and thus work out of multiple computers: my work-laptop a desktop at my primary client my desktop at home an android smartphone an android tablet Likewise, I have multiple accounts: A Microsoft Exchange (2010 AFAIK) account A Microsoft Exchange (2007 AFAIK) account A gmail account The most important thing I need is the ability to have events in one calendar affect the free / busy status of all other accounts (so that if I am busy on Monday 9am with an event from my employer's account, it will show that time as busy in my client's account, and in the gmail account. Second thing I need is a unified view of all of my accounts' info: Appointments, email, tasks, and contacts (in that order of importance). I've already tried outlook synchronization tools such as gSyncit, to sync both exchange accounts with gmail, but this creates a mess when updating appointments (deleted appointments sometimes return, timestamps revert). Is there perhaps some way to at least synchronize the free/busy state in a way that all of my calendar apps / accounts will look there to see if I can be invited? Just solving that would be well worth my while. Thanks, Assaf

• Is Samba "remote browse sync" possible across OpenVPN tunnel?

  - by John Reynolds

  I'm connecting 2 TomatoUSB (Shibby build on WNR3500L v2) routers with an OpenVPN routed connection: ----------------------- ----------------------- | Router 1, subnet 20 | <--tunnel--> | Router 2, subnet 21 | ----------------------- ----------------------- Router 1 is the OpenVPN server and Router 2 is a client. Clients attached to the routers on both subnets can ping clients on the other subnet, so the tunnel and routing works. I've enabled file sharing on both, in order to get their Samba WINS servers running. Is it possible to get name resolution across the tunnel? I've tried remote browse sync = 192.168.21.1 in /etc/smb.conf on the server side, to no avail. Also tried using the IP adress that the client gets from the OpenVPN address pool (usually 10.8.0.something), but still no joy.

• How do I daemonify my daemon?

  - by jonobacon

  As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients. Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients. I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc. The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask: How can I treat it as a service that is run for the current user service (not a system service right now)? How do I ensure I can start, stop, and restart this session service? When packaging this, how do I ensure that it installs it as a service for the user's session and is started on login etc? In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-) Thanks! Jono

• How do I use a URL path instead of a file path in an Open File dialog in Mac OSX or ChromiumOS?

  - by Chris

  In Windows 7 (and perhaps earlier), the default "Open File" dialog box allows you to type a full URL into the "File name" section as if it were a file path, e.g. "http://www.example.com/pic.gif" instead of "C:/windows/pictures/pic.gif". When uploading a file to a website on the client side - say, an image - this allows the client to upload a picture located on a server accessible via the URL instead of downloading the image, saving it locally, then referencing the local image in the "Open File" dialog. It's a great option for Windows users. I have three separate questions: What is this procedure formally called? How do I describe this succinctly so that my searches for more information are fruitful? Can something similar be done in Mac OSX, Chromium OS, or a Linux environment? If so, how? Thanks!

• Good technologies for developing a modular server component in .net?

  - by nubbers

  I am using WPF, Prism and Unity to develop the user interface for a .net application. The UI will run from a PC, but I also need to develop a separate complex server component that will provide services to the PC component via WCF. Prism and Unity have proved to be of great value in creating a modular application, at least as far as the user interface is concerned. I would also like to make the server component modular, but I cannot find anywhere what techniques, patterns and technologies are suitable. I have considered: Unity or one of the other DI containers Selected parts of Prism, such as modules and events Are these suitable for developing a modular server component? Or are these UI technologies only and should I be looking at something completely different?

• Website address hacked, emails created but not showing in manage your account

  - by ProfMJMcG

  I have a website, thebleudoor.com. It is hosted by yahoo. It gets 2000-3000 hits a day and has been for at least 5 years. A few months ago, as admin of the website, I started getting bounced back emails from newly created emails like [email protected]. Yahoo only shows 2 emails for my account. They said they can't do anything about it. Now, my "spam hacked email accounts" are getting spam. They haven't altered or used my website or email or bank info, just the good name of my website. Is there anything I can do? Do I need to be concerned? Changing my provider won't really help will it? Thank you.

• Why does this service refuse to start on Windows server 2003?

  - by PenguinCoder

  We have a Windows 2003 server with Cebos MQ1 (ver. 7 and ver. GRI) products installed that have been operational for years. After installing Microsoft 2010 C++ Redistributable package needed for other development, the MQ1 GRI service now fails to start. Event logs showed that two additional updates (.NET4 and the 2010 C++ Redistributable SP2) where installed by the redistributable as well. As soon as we discovered the MQ1 service was not starting properly, we removed these three installed packages. However the service still does not start; the dialog that pops up states 'The service started then stopped. '. Event logs when we attempt to start the service show nothing; IE: No errors, crashes, failures, or other information related to this service. Executing the MQ1Serv.exe directly specifies an issue of 'Missing command line operation, must specify install, uninstall and company abbreviation.' sc query MQ1Service(GRI) shows a clean exit for the Win32ExitCode of 0x0. Attempting to reinstall the client or server software gives an error of 'The procedure entry point ReInitializeCriticalSection could not be located in the dynamic link library KERNEL32.dll.' at the 'Registering Libraries' stage. At this point, further research has stated that the required function is in URL.dll and to verify the library is not corrupted. Running an sfc /scannow on the server has replaced a few DLLS; including the URL.DLL to versions from 2005. This actually broke other applications which required a reinstall (one of them being IE 7). After reinstall and updates, url.dll version is 7.0.5730.13 (2009) and Kernel32.dll is version 5.2.3790.4480 (2009). The MQ1 GRI service still will not start, specifying the same error as previous 'Service started then stopped'. Running a disassembler on Kernel32.dll and Url.dll show no functions named ReinitializeCriticalSection. Attempting the reinstall of the MQ1 client and server as well as starting the service again, fails once more. However, setting the compatibility mode on the MQ1 client install exe to 'Windows 95' actually gets the program to install. Setting the compatibility mode on the MQ1 server service does not enable it to start. I have been researching this problem for nearly a week and besides the advice to scan and replace url.dll, have come to no successful conclusions. This service was operational prior to the 2010 C++ install, without any additional parameters or settings. After removing the C++ install and all servicepacks/updates it installed silently, still does not correct the issue of the MQ1 GRI service not starting. Q: Has anyone else run into this or similar issue while attempting to get a service initialized? What have I overlooked or what else can I try in order to get this service started??

• Apache certificates for some urls not working

  - by Vegaasen

  We are having a rather strange problem with a Apache-installation. Here is a short summary: Currently I'm setting up Apache with https, and server-certificates. This is fairly easy and works straight out of the box - as expected. This is the configuration for this setup: Listen 443 SSLEngine on SSLCertificateFile "/progs/apache/ssl/example-site.no.pem" SSLCertificateKeyFile "/progs/apache/ssl/example-site.no.key" SSLCACertificateFile "/progs/apache/ssl/ca/example_root.pem" SSLCADNRequestFile "/progs/apache/ssl/ca/example_intermediate.pem" SSLVerifyClient none SSLVerifyDepth 3 SSLOptions +StdEnvVars +ExportCertData RequestHeader set ssl-ClientCert-Subject-CN "%{SSL_CLIENT_S_DN}s" RewriteEngine On ProxyPreserveHost On ProxyRequests On SSLProxyEngine On ... <LocationMatch /secureStuff/$> SSLVerifyClient require Order deny,allow Allow from All </LocationMatch> ... <Proxy balancer://exBalancer> Header add Set-Cookie "EX_ROUTE=EB.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED BalancerMember http://10.0.0.1:7200 route=ee1 retry=300 flushpackets=off keepalive=on BalancerMember http://10.0.0.2:7200 route=ee2 retry=300 flushpackets=off keepalive=on status=+H ProxySet stickysession=EX_ROUTE scolonpathdelim=Off timeout=10 nofailover=off failonstatus=505 maxattempts=1 lbmethod=bybusyness Order deny,allow Allow from all </Proxy> RewriteCond %{REQUEST_URI} !^/index.html [NC] RewriteRule ^/(.*)$ balancer://exBalancer/$1 [P,NC] ProxyPassReverse / balancer://exBalancer/ Header edit Set-Cookie "(.*)" "$1;HttpsOnly" ... So - everything works fine and as expected for all of the pages that are not a part of the LocationMatch-directive. When requesting something that matches the LocationMatch-directive, I'm asked for a certificate (hence the SSLVerifyClient required attribute) - and getting all the correct certificates in my browser that is based on the root/intermediate chain. After choosing a certificate and clicking "OK", this is what pops up in the apache logs: [ssl:info] [pid 9530:tid 25] [client :43357] AH01998: Connection closed to child 86 with abortive shutdown ( [Thu Oct 11 09:27:36.221876 2012] [ssl:debug] [pid 9530:tid 25] ssl_engine_io.c(1171): (70014)End of file found: [client 10.235.128.55:45846] AH02007: SSL handshake interrupted by system [Hint: Stop button pressed in browser?!] And this just spams the logs. What is happening here? I can see this configuration working on my local machine, but not on one of our servers. There is no configration differences between the servers, only minor application-wise-changes. I've tried the following: 1) Removing CA-certificate-checking (works) 2) Adding required CA-certificate for the whole site (works) 3) Adding "SSLVerifyClient optional" does not work 4) ++ Server/Application Information Local: -OpenSSL v.1.0.1x -Apache 2.4.3 -Ubuntu -mpm: event -every configuration should be turned on (failing) server: -OpenSSL 0.9.8e -Apache 2.4.2 -SunOS -mpm: worker -every configuration should be turned on Please let me know if more information is needed, I'll provide it instantly. Brief sum-up: -Running apache 2.4 -Server certificates works just fine -Client certificates for some /Locations does not work, fails with errors PS: Could it be related with the OpenSSL version and the "Renegotiation" stuff related to TLS/SSLv3?

• https (SSL) instead of http

  - by user1332729

  I am building myself a new website, out of privacy and security concerns I am contemplating trying to make it https only. It will be mobile-friendly using media queries but I am concerned--especially for mobile users--about the increased bandwidth. How much will doing so increase my bandwidth or slow load times? For pages where I'm not transferring sensitive information, should I leave external links (to a jQuery library, or a web font for instance) in http? Simply put, I have read articles saying the entire web would be more secure if everything was SSL but my actual knowledge of implementation is limited to payment gateways and log-in pages and such. I apologize for the open-ended nature of the question but anything, even just simple answers to the specific questions is welcomed.

• Remote Desktop Encryption

  - by Kumar

  My client is RDP 6.1 (On Windows XP SP3) and Server is Windows Server 2003. I have installed an SSL certificate on server for RDP. In the RDP settings (General tab), the Encryption method is set to SSL/TLS 1.0 and Encryption level is set to "Client Compatible". I have following questions In this case is it guaranteed that all communication is encrypted even when I remote login to the server? I mean pwd is encrypted Does RDP always use some kind of encryption even if there is no SSL certificate installed on the server? In this case I do not see security lock in the connection bar. When I set encryption level to "High" then I see security lock. I do believe that communication is both cases will be encrypted. Is it true? Please reply to my questions Thanks in advance Kumar

• Input prediction and server re-simultaion

  - by Lope

  I have read plenty of articles about multiplayer principles and I have basic client-server system set up. There is however one thing I am not clear on. When player enters input, it is sent to the server and steps back in time to check if what should have happened at the time of that input and it resimulates the world again. So far everything's clear. All articles took shooting as an example, because it is easy to explain and it is pretty straightforward, but I believe movement is more complicated. Imagine following situation: 2 players move towards each other. A------<------B Player A stops halfway towards the collision point, but there is lag spike so the command does not arrive on the server for a second or so. Current state of the world on the server (and on the other clients as well) at the time when input arrives is this: [1]: -------AB------- The command arrives and we go back in time and re-simulate the world, the result is this: [2]: ---AB----------- Player A sees situation [2] which is correct, but the player is suddenly teleported from the position in [1] (center) to the position in [2]. Is this how this is supposed to work? Point of the client prediction is to give lagged player feeling that everything is smooth, not to ruin experience for other players. Alternative is to discard timestamp on the player's input and handle it when it arrives on the server without going back in time. This, however, creates even more severe problems for lagged player (even if he is lagging just a bit)

• What's the best web entrepeneur's conference to go on

  - by user4845

  Our dream as business partners was always to go to a conference overseas. Now that we can finally afford to, we have no clue of which one to go to. Which conference would you guys suggest from a web entrepeneur's point of view, if there were just one to go to? Perhaps something that included a bit of marketing, new thinking, innovation, inspiration. We were very keen on Google IO previously, but were concerned that it would be very Google product focused. Huge thanks!

• PuTTY automatically supply password

  - by Kyle Cronin

  I have a situation where I need to have PuTTY (or another SSH client for Windows) automatically log into another machine via SSH. I realize that this isn't a good idea security-wise, but unfortunately I'm constrained by the limitations both on the client and the server. The best solution would be to have a shortcut or script on the desktop that, when double clicked, will connect to the server and automatically log in. Can I do this with PuTTY? I am willing to explore public key authentication, but I'm not sure where the PuTTY key resides or how to copy it to the server, as the app starts automatically upon login.

• Slow WLAN file transfer between server and tablet

  - by user266985

  My file server is running Ubuntu 12.04 and I'm sharing files from it over samba. It is connected via gigabit ethernet. My desktop, running Windows 8.1, is also connected via gigabit ethernet. I can transfer files between the two and completely saturate that gigabit pipe. However, I just got a Surface Pro 2, and I'm trying to stream HD movies from my server to the device over WiFi. For some reason, I can't break much past 1.5MB/s transferring files over the network. I've tried streaming through XBMC and a standard file copy; no difference. To add the confusion, if I connect to my guest network and then use my VPN server (installed on the router) to access the file server, I get around 3.2MB/s. I've been running diagnostics to determine the root and I think I've found it but I have no idea what is causing it or how to fix it.

• Looking for 'WinHlp32.exe compatible' replacement for free redistribution under vista and windows 7

  - by richardboon

  Our software installs a package of legacy software for the client, some of it has old hlp file from 3rd party vendor requiring winhlp32.exe (note: we have no legal right to modify the hlp). Those client may only have cd/dvd and might not have internet access, etc. So I need a free 'WinHlp32.exe compatible' replacement for our redistribution under vista and windows 7. Background of problem: -Microsoft stopped including the 32-bit Help file viewer in Windows releases beginning with Windows Vista and Windows Server 2008. -Starting with the release of Windows Vista and Windows Server 2008, third-party software developers are no longer authorized to redistribute WinHlp32.exe with their programs. http://support.microsoft.com/kb/917607

• Would it be more efficient to handle 2D collision detection with polygons, rather than both squares/polygons?

  - by KleptoKat

  I'm working on a 2D game engine and I'm trying to get collision detection as efficient as possible. One thing I've noted is that I have a Rectangle Collision collider, a Shape (polygon) collider and a circle collider. Would it be more efficient (either dev-time wise or runtime wise) to have just one shape collider, rather than have that and everything else? I feel it would optimize my code in the back end, but how much would it affect my game at runtime? Should I be concerned with this at all, as 3D games generally have tens of thousands of polygons?

• I try to access a NFS mount via FTP. It works but the FTP Dir listing is very slow

  I mount an NFS using this command: mount -o rsize=8192,wsize=8192,timeo=14,intr serverip:/directory /mnt/directory However the mount appears on the client as expected a cmd like "ls -a" work pretty fast on the nfs mount. But when I try to list the mounted directory via FTP it gets very very slow ( 1.250 bytes in 160,39s (0,01KB/s) ). But surprisingly downloading files via FTP from nfs work with normal speeds. I tested several values for rsize and wsize parameter with no success. Both client and server are running Debian squeeze and NFSv4

• How to make sure clients update their browser cache when my website is updated?

  - by user64204

  I am using the HTTP 1.1 Cache-Control header to implement client-side caching. Since I update my website only once a month I would like the CSS and JS files to be cached for 30 days with Cache-Control: max-age=2592000. The problem is that the 30-day period defined by Cache-Control doesn't coincide with the website update cycle, it starts from the moment the users visit the site and ends 30 days later, which means an update could occur in the meantime and users would be running with outdated content for a while, which could break the rendering of the website if for instance the HTML and CSS no longer match. How can I perform client-side caching of content for periods of several days but somehow get users to refresh their CSS/JS files after the website has been updated? One solution I could think of is that if website updates can be schedule, the max-age returned by the server could be decreased every day accordingly so that no matter when people visit the website, the end of caching period would coincide with the update of the website, but changing the server configuration every day goes against one of my sysadmin principles (once it's running, don't touch it).

• Do you use your personal laptop for work? [closed]

  - by davekaro

  We're trying to get our company to let us use our own personal laptops for client work. We've agreed that any code/data will be encrypted using something like TrueCrypt, in case a laptop is stolen or lost. However, the company is still skeptical and not sure they want to allow us to use our personal machines for development. They would rather buy us laptops... but we want to use MacBook Pros and they don't want to pay for them. Even if they did buy us laptops, we would stil have the issue of needing to encrypt the code/data in case of theft/loss. Do you use your own laptop for work? What are the arguments for/against this? UPDATE: Thanks for all the responses, its given us a lot to think about. This was originally brought up because we were asking for a "personal loan" to buy new laptops for ourselves, and then we threw in there that we would use these laptops for work too - since right now we use our personal laptops occasionally, e.g. at client site or weekend support.

• Will this SPF record restrict delivery of email for the original domain?

  - by user199421

  As part of the product we offer we send emails on behalf of our clients. Because the emails don't come from an IP associated with the client they are sometimes flagged as spam. We advised some of our clients to add an SPF record approving us to send emails on their behalf. We saw immediate improvement in deliverability rates after making the change however one of our clients was notified by his hosting provider that the SPF record we suggested to add would "slightly restrict" all emails that don't come from our servers (including our client's own servers). The record we use is this: v=spf1 a mx include:ourdomain.com ~all So my question is if the warning we received about this is correct and if so why and what can be done to solve this (allow sending email both from original domain and by ourselves).

• Moving from a traditional in memory Java session to persistent storage sessions

  - by Benju

  We have decided to take the plunge and move from using a typical java session provider in Tomcat/Jetty/etc to persisting everything to a central datastore. We are looking at using MongoDB for this. A few options come to mind... http://wiki.eclipse.org/Jetty/Tutorial/MongoDB_Session_Clustering This is nice because it will "auto-magically" persist our session to a Mongo installation. I am concerned however that we will not have fine grained control of what is happening. https://github.com/mattinsler/com.lowereast.guiceymongo/ GuiceMongo is interesting as it integrates with Guice. Perhaps we could persist everything via this ORM. Has anybody had to deal with this kind of move? It seems that moving from in memory to persistent session storage has a lot of gotchas.
