• Xorg fails to start under Ubuntu

  - by den-javamaniac

  I'm running desktop Ubuntu 9.10 on my Dell laptop. Previously it was Ubuntu 9.04. After some period of time (lets say 3-4 months) my X fails to start automatically after some restart calls. If that takes place my network manager applet doesn't start either (after I do startx). Can any one point out what I'm missing/what's the problem? EDDITED I get a perfect server boot meaning there's no Xorg started. Command line interface is all I get starting from login and further.

• Use the &ldquo;using&rdquo; statement on objects that implement the IDisposable Interface

  - by mbcrump

  From MSDN : C#, through the .NET Framework common language runtime (CLR), automatically releases the memory used to store objects that are no longer required. The release of memory is non-deterministic; memory is released whenever the CLR decides to perform garbage collection. However, it is usually best to release limited resources such as file handles and network connections as quickly as possible. The using statement allows the programmer to specify when objects that use resources should release them. The object provided to the using statement must implement the IDisposable interface. This interface provides the Dispose method, which should release the object's resources. In my quest to write better, more efficient code I ran across the “using” statement. Microsoft recommends that we specify when to release objects. In other words, if you use the “using” statement this tells .NET to release the object specified in the using block once it is no longer needed.   So Using this block: private static string ReadConfig()         {             const string path = @"C:\SomeApp.config.xml";               using (StreamReader reader = File.OpenText(path))             {                 return reader.ReadToEnd();             }         }   The compiler converts this to: private static string ReadConfig1() {     StreamReader sr = new StreamReader(@"C:\SomeApp.config.xml");       try     {         return sr.ReadToEnd();     }     finally     {         if (sr != null)             ((IDisposable)sr).Dispose();     }   }

• safe to setup NAS in virtual image with web server?

  - by Erik

  My current setup is Ubuntu Desktop, running Apache + MySQL + PHP stack. I use this image to host my small website to the outside world. I want to now run a virtual machine on the box, that will act as the FreeNAS box for my internal network. This sounds like a bad idea if the website gets hacked/attacked. Should I just give up and grab a dedicated machine instead? Can I instead virtualize the web server and NAS side by side on this machine?

• Windows W8, L8 and now H8

  - by raccoon_tim

  Windows 8 is having to endure with a lot of headwind at the moment. The weather forecast doesn’t appear to improve in the near future either with prominent game developers and publishers taking to the barricades accusing Microsoft of building a closed ecosystem. I am forced to side with this opinion as I too see services the likes of Steam as playing an important role in the gaming world, which just happens to be an industry that cannot be sidelined. What Microsoft is attempting to do is merge the PC and mobile markets. The Windows Marketplace is to be the only place where you can purchase Windows applications in the future starting now with Metro apps. This is what Apple, Google and Microsoft have been doing with mobile devices for some time now and it’s what we have all come to expect. The PC market is different, however. It has always been open, which has resulted in a diverse market allowing for third parties to build successful distribution and marketing networks. You could argue that Microsoft is just doing something that Steam has been doing for a long time now but the difference is that Microsoft would own both the marketplace AND that operating system, which would eventually give it dominance over the whole Windows application distribution network. Currently there is no real alternative to Windows in the PC gaming world but I would expect to see Mac OS and Linux getting more popular if Microsoft does not notice the signals coming from the gaming industry and choose to once again open up the markets on the PC.

• Is there a way to customize items on the right side of start menu in Windows 7?

  - by Basara

  OK I know I can right click on it and select properties... But it only allows me to decide whether an item is shown or hidden. What I want is, adjust item position on the start menu right side. More specifically, I want to put the item "games" in the same group where personal folders are. It makes perfectly no sense to put "games" with "computer" and "network" in same group. Or is there a registry tweak can make this possible? Thanks.

• curl makes a site work externally once run locally (apache)

  - by Kyle_at_NU

  Currently when I visit mysite.mydomain.com external to the local network I get in the browser: This is the default web page for this server. Nothing to see here. This is not even the "It Work's" Apache page. Then if locally (Apache2 on Ubuntu Server 12.04 with curl installed ) type: curl mysite.mydomain.com I get the site I expect. Then the next time i visit the page externally I get the correct site. Has anyone seen this before? Tips/Suggestions?

• Video streaming and internet browsing on different bands/frequency

  - by user47207

  I have a Netgear WDNR37000 which allows clients on a 2ghz or 5ghz to access the internet and see every client and device on the network. I have a computer with two nics, one that is in the 2ghz range and the other on the 5ghz range. My specific problem is that I would like to serve my video streams (hulu, ps3mediaserver, playon) to my ps3 on the 5ghz band while internet browsing is routed to the 2ghz band. This is so that the video streams aren't affected by general internet use. While the easiest solution would be to disable internet access on the 5ghz apn, I would like to know of a solution that would not require that.

• Outlook '10 hangs often, IMAP sync

  - by user23150

  We have 3 employees using IMAP to sync with their Desktop and Android Phones. Two are using 70% of their accounts storage, another is using 80%. They all have similar counts on folder structure, etc. The employee with the 80% storage is constantly having Outlook freeze on them for up to 5 minutes at a time. I realize this is Outlook connecting and doing activity on the server, but no one else has this problem. In fact, one user with the 70% storage used uses a very slow laptop, and doesn't have freezing issues. The network is the same, the settings are the same - at a loss how to proceed? Obviously "Outlook is a crummy IMAP client" doesn't help management...

• Cannot Ping PS3 Using a Wired Connection

  - by Post

  PS3 is using the inbuilt wireless network adapter (I cannot change this) When I try to ping the PS3 from ANY computer which is on a wired ethernet connection, I get Request Timed Out errors. Whenever I ping from a computer with a wireless connection, it works just fine. To be clear: Pinging from Wireless PC to Wireless PS3 works Pinging from Wired PC to Wireless PS3 fails I have tried this on several PC's and Laptops all with the same results. As an attempted solution I have set up static IP's on all related devices. More information: Default Gateway = 192.168.2.1 PS3(wireless) = 192.168.2.100 PC(wired) = 192.168.2.99 Subnet Mask(for both devices, I have made sure) = 255.255.255.0 Thanks

• Amazon EC2 IPSEC

  - by John Qualis

  I have configured a ubuntu 12.04 64-bit server machine on Amazon AWS to act as a strongswan IPSEC server. I want to connect to it from my MAC OSX Lion's inbuilt IPSEC client. The OSX machine is in my home network.

The ssh connection works file but the IPSEC connection fails. What credentials/configurations should I provide for an IPSEC connection from my OSX client to AWS ubuntu server? My OSX machine is behind an ISP provided modem/router. Appreciate any help and thanks in advance

• Is there a way to get a shared spreadsheet to update without closing and reopening?

  - by Mike

  Using Excel 2010, I have a spreadsheet that is used by 3 different people at any one time. But if one person has the spreadsheet open on there PC the other people can only view it as read only. I have since shared the workbook and put the spreadsheet on a shared network drive and now they can all view the spreadsheet at the same time and edit it at the same time. The problem is that nobody can see the changes that the other users have made unless the close out of the spreadsheet and open it up again to view the changes. I have checked the settings of the shared workbook and on the advanced tab have tick the option that updates the information every 5 minutes but the information does not update until you close out and open the spreadsheet back up again. How can I fix this problem?

• Is there any way to automatically prevent running out of memory?

  - by NoahY

  I am often running out of memory on my VPS ubuntu server. I wish there was a way to simply restart apache2 when it starts running out of memory, as that seems to solve the problem. Or am I just too lazy to fix the problem? I do have limited memory on the server... Okay, more information: I'm running apache2 prefork, here are my memory settings (i've been tweaking them...): StartServers 3 MinSpareServers 1 MaxSpareServers 5 MaxClients 150 MaxRequestsPerChild 1000 The VPS has 1 GB of ram, running ubuntu 11.04 32-bit. As for scripts, I have a wordpress network with 5 blogs, an install of AskBot (a python/django stackexchange clone), and an install of MediaWiki that isn't really used. There is also a homebrewed mp3 script that accesses the getid3 library to display information on lists of podcasts, and it seems to be throwing some php errors, not sure if that's the culprit...

• CSS file not served by IIS 7.5 after multiple clear cache refreshes in a row in browser

  - by KenB

  We are experiencing an interesting issue with IIS 7.5 static caching and a css file. When we use IE to hit the page in question everything works fine - 200 OK on css file. When we refresh the page it works fine - 304 Not Modified on css file. When I refresh again with control key it reloads fine - 200 OK on css file. Now if I do a control key + refresh multiple times in a row really fast the css fails to load and in the developer tools network it says "Loading..." for the css file and it hangs never coming back. Any ideas?

• Redirect audio from laptop to desktop over LAN

  - by Ram Rachum

  I want to be able to play a song on my laptop and have it sound through my desktop's (infinitely better) speakers. If you're familiar with Input Director: I want something that is to audio what Input Director is to mouse/keyboard. I want something that automatically redirects all audio from the laptop to the desktop in real time, and I want that solution to require, like Input Director, minimum maintenance. Beyond the initial setup, I don't want to have to babysit the program that does this. I want something that launches automatically with Windows and just works, and also allows me to cancel it whenever I want. And also doesn't go crazy when the laptop is turned on in a different network where the desktop computer isn't available. Any suggestions for such a program? (I use Windows XP on both computers.)

• Number of malicious attacks defended/done on the average user daily [closed]

  - by DalexL

  As a web hoster, it is very easy to notice the large amounts of exploit/abuse attempts done on my servers. Out of curiosity, how often are these attempts done on the average user? I'm assuming almost all of them are prevented just by simple security protocols in place by their browsers, local network, etc. How many attempts, on average, are committed against a single user daily through any method? (email, internet, downloads, etc.)? If known, what percentage of these things are blocked by the average users security? I tried googling but I was having a hard time getting the right search terms together.

• Wifi and eth behavior

  - by r00ster

  I have a wireless router 150M Wireless Lite N Router Model No. TL-WR740N / TL-WR740ND. Normally, when I'm connected to the local network using eth0 I can ping other machines by issuing ping name. When I'm connected through wifi I have to issue ping name.domain.com. The machine is only visible in intranet. How to achieve the same behavior with wifi? The second problem is, that I can not connect to some external sites through wifi but through eth everything is ok. I guess that is related to some port forwarding, but I'm not sure. How can I resolve this issue? EDIT: I'm using Linux Mint.

• Avoid Windows Explorer to load complete executable file

  - by user13001

  On Windows Vista, when browsing to a network folder containing executables, Windows Explorer seems to load all the files completely just to be able to show the executable icon (the resource monitor indicates loads of traffic during the loading of the directory) On XP only a part of the file is loaded. Is there a way to avoid the complete loading of these files? Note that disabling my anti virus does not help. Update: This only happens with for executable linked with /SWAPRUN:NET. Microsoft confirmed this as a bug in Vista, but they seem not very eager to fix this.

• Enterprise Level Monitoring Solution

  - by Garthmeister J.

  My company is currently looking to replace our current solution used for monitoring our web-based enterprise solutions for both up-time and performance. Please note this is not intended to be a network monitoring-type solution (internally we currently use Nagios). If anyone has a provider that they have had a positive experience with, it would be much appreciated. Here is a list of our requirements: • Must have a large number of probes/agents around the globe to be representative of our customer base • Must have a flexible scripting capability to automate multi-step user actions • 24 hour a day monitoring • Flexible alerting system • Report generation capability • Mimic browser specific monitoring (optional, not a must-have)

• Wireless option grayed out in Windows Mobility Center

  - by thomasvdb

  We currently have a Lenovo ThinkPad L512 which can't connect to wireless networks. He simply indicates he can't find any networks. Other notebooks (also ThinkPad L512-notebooks) in the company do find the network so nothings wrong with the configuration of the wireless router. As indicated on answer.microsoft.com, I should check Windows Mobility Center and enable the entry "Turn Wireless On". Unfortunately this option has been grayed out. How can I enable this option? There isn't a physical switch on the laptop to turn on the wireless.

The bitdefender's firewall also shows network activity. Is there any hidden apps downloading? How to fix this?

• is using Hosts for resolving a sql-server more performant?

  - by Ice

  Hi, we have a legacy application which uses a access.mdb with hundreds of ODBC-connected tables on a sql-server. the access.mdb contains nothing else than these odbc-connections. Now we consider to use a virtual sql-servername for these odbc connections and resolve it in the local hosts-file with the ip-address of the real sql-server. Like this we can easy switch between a test-sql-database server and the the server for production in changing one single entry in the hosts. EVERYTHING works fine and now comes the question: Could it be that this is more performant because there is one single point on resolving the sql-server (name or ip-address)? Is there something like a network-cache / DNS-Cache? peace Ice

• What is causing my wireless problems?

  - by user34629

  I have a Dell XPS M1330, since I moved to my new house, the wireless barely works on it, my housemates report no problems, so I guess it's something to do with my laptop. It's eratic in normal mode, sometimes not working for days, usually working on-and-off, forcing me to reload pages a few times before they work, etc. It works perfectly in safe mode, the driver I'm using is the Intel PRO/Wireless 3945ABG Network Connection, version 12.4.4.5, with a date at 26/10/2009, the most recent one I could find, bluetooth is not enabled, and I'm running Vista 32-bit Home Premium, which it shipped with. I also tried disabling IPv6 and resetting the IP stack, both to no avail. Can anybody help me?

• Where does traffic shaping typically take place?

  - by eekmeter

  As part of upgrading our network infrastructure we are looking to traffic shape our bandwidth since we only have about 3Mb down / 1 Mb up. We're looking to prioritize it so that web browsing gets priority and in the future some VOIP might be added in as well. Internal LAN traffic doesn't need to be controlled just our outbound connection. I've been looking at Cisco hardware and it seems that several of their products do shaping at the core switch, firewall, and router level. I'm wondering where does shaping normally take place? Is it normally done at the router, core switch, or firewall?
