• Laptop connectd to 2 VPNs (1st for Internet over WiFi, 2nd to access shared folders on another network) is failing to route traffic over 2nd VPN

  - by Triynko

  I set up a VPN on Windows Server 2008 through its routing and remote access services. I connected to the VPN, and configured the client to allow for split tunneling (Internet traffic goes to my default gateway, and traffic directed to the VPN server goes through the VPN gateway). I had to adjust the routing table, adding an entry to ensure traffic to my VPN server goes through the tunnel by running the command "route add [VPN.IP] mask 255.255.255.255 [VPN.GATEWAY.IP] IF [VPN_INTERFACE_#]". Adding the correct route makes everything work flawlessly on all my machines, except for one. The problematic machine is a laptop that's not directly connected to a network. It connects to WiFi, and then connects to a VPN to obtain internet access. Finally, it connects to the target VPN server for file sharing. The "route add" trick doesn't work for that laptop, I'm assuming because it's connected to two VPNs, and I'm getting the routing wrong. Can anyone familiar with routing explain what routes I may need to add?

• Xmodmap: six characters to one key and two layouts?

  - by sup

  I know how to have six symbols on one key thanks to this question: Xmodmap: Six characters to one key? However, when I have two layouts and switch them, weird things happen. I have the following (well, different, but this is easier to talk about) line in my xmodmap: keycode 31 = a A b B c C When I log in, everything works as you would expect. Pressing key 31 give a, with Shift A, with AltGr c and C respectively and with ISO_Level3_Shift. However, when I change the layout, key 31 gives me b and B with shift and c and C with AltGr. This is on Ubuntu 11.10 under Ubuntu. Does anybody undestand what is happening? Could I restrict xmodmap to just one layout?

• How should I structure the implementation of turn-based board game rules?

  - by Setzer22

  I'm trying to create a turn-based strategy game on a tilemap. I'm using design by component so far, but I can't find a nice way to fit components into the part I want to ask. I'm struggling with the "game rules" logic. That is, the code that displays the menu, allows the player to select units, and command them, then tells the unit game objects what to do given the player input. The best way I could thing of handling this was using a big state machine, so everything that could be done in a "turn" is handled by this state machine, and the update code of this state machine does different things depending on the state. However, this approach leads to a large amount of code (anything not model-related) going into a big class. Of course I can subdivide this big class into more classes, but it doesn't feel modular and upgradable enough. I'd like to know of better systems to handle this in order to be able to upgrade the game with new rules without having a monstruous if/else chain (or switch / case, for that matter). Any ideas? What specific design pattern other than MVC should I be using?

• Windows Recovery partition unusable after Ubuntu 12.04 install on Eee PC 1005P

  - by Crivat Camilar

  Installed Ubuntu 12.04 over the secondary (D:) partition with Grub2 handling multi-boot. Never accessed the 'Recovery' option in the boot menu until Windows7 Starter became unusable due to HDD failure (bad sectors on C:). Tried creating an USB recovery stick using the OEM's recovery application (F9) on hidden partition: all I got was a clean C:\ and an error telling me the recovery images cannot be found [R:\recovery\windowsre\ - or something very much like that] although everything is there (changed 'hidden' flag to check and copy contents). Nothing happens upon pressing F9, then Grub takes over giving the recovery option. The application starts but halts about 30s after initializing, very briefly displaying the error message above. I guess every time it goes through this it actually wipes C:\ but crashes immediately afterwards not being able to find what-ever .wim image files it needs. How to make it work?

• Cisco WLAN Controller not pushing out DHCP addresses, what else could it be?

  - by Name

  On our Cisco WLAN Controller web interfaces, in Controller Interfaces, I have made a new interface with these settings: VLAN Identifier 202 IP Address 172.16.202.1 Netmask 255.255.255.0 Gateway 172.16.202.254 Primary DHCP Server 172.16.100.3 Secondary DHCP Server 172.16.100.2 Port: LAG I've also made a new WLAN and assigned it to the above interface. I have saved changes. But our wireless devices, although they seem to authenticate with the WLAN fine, they always get stuck on "obtaining DHCP address", so it seems the WLAN Controller isn't pushing out DHCP addresses to our devices. We do have a DHCP scope for the above in Windows Server 2008 R2 and everything there seems fine. If I connect a device with a static address (e.g. 172.16.202.10), it will connect. Stuck on what to do :(

• Writing better timesheet

  - by gunbuster363

  Recently, my company started to require us to fill out a monthly timesheet, writing down everything you do in office. A timesheet contain 29-31 days, depends on the number of days of the month. I need to write the things I did in every row of the excel file, which represent a day. This timesheet embarrasses me, because something like this can happen: I spent Monday writing a program, and the program was done. Because my boss didn't give me other program to write, basically I am just sitting there and pretending I am busy in the following days before my boss gives me another assignment. Of course I should not write it in the timesheet as it is. I can write it in the timesheet that I write the program using 4 days, but it makes me feel very inefficient. I can separate the process into 1) write the program, 2)deploy the program, 3)test the program, but that can make the process so long like 3 weeks, really. Have you encountered such a situation? How would you deal with this? EDIT: some people said I should be more proactive about asking for more assignments, but here is the situation: the boss of my boss gives some jobs to my boss, then my boss gives the jobs to me, sometimes I can also see my boss being quite less busy. One of my colleagues said that I should not ask for another assignment in a proactive manner, because it would be a headache for my boss to think a job out of nowhere for me. I don't want the things turn out like that, really.

• games and movies become too slow after some time

  - by ishaq

  On my gaming desktop, I was fixing my desktop's power supply when something seemed to burn (I got that stinging burning smell). However when I turned ON the computer (it was OFF before), everything seemed to be fine. However, I have noticed that now it becomes too slow if I play a game or movie on it. I am talking about the computer becoming painfully slow after about 5 minutes into the movie/game (it works fine otherwise e.g. browsing), it becomes so slow I can see individual frames from movies/games. What could be the problem? A fried video card? friend memory (RAM), something else? My system's configuration is: Intel Core i7 CPU 3.40GHz 8GB DDR3 RAM 2TB WDC HDD NVIDIA GeForece GT 220 (1GB) Thermal Take Commander MS1 Chassis ( http://www.thermaltakeusa.com/Product.aspx?S=1394&ID=2051 ) mainboard: Intel DH67CL AAG10212-208 Realtek High Definition Audio

• Access a samba mount from an ssh connection

  - by Android

  I have Ubuntu 9.10 on my computer. I have made a samba mount to a windows computer. This works fine when I am on the Ubuntu computer directly. When I go to another computer and connect to Ubuntu with SSH. I can connect fine and everything works but the folder my mount is in appears empty. I have only 1 account and it has permissions on the file etc. When on the computer directly it all works perfectly, it is only when connecting with SSH that isn't visible. What am I doing wrong here? I made the mount with smbmount //computer/folder mount -o username=username,password=password Even if I run this command on the SSH connection then it is the same, visible on the computer directly but not on SSH.

• Setup Email Server (sendmail + dovecot + squirrelmail)

  - by henry

  I am in the process of setting up my very first email server. I can get everything up and running (thanks to apt-get). Manage to tie the users with system users. Now I am setting up virtual users for dovecot. But however, I also notice I can setup users in sendmail itself. Why is it so that you can setup users in 2 different places. Other mail server will send to the user in sendmail or dovecot?

• Somehow Google considers a properly 301'd URL as 200 and is still indexing the new content in old page?

  - by user2178914

  We redirected all the old URL's to new ones properly using htaccess. The problem is Google, somehow is still finding content in the old page(which it shouldn't) and stores it in the cache rather than the new URL. For eg: Old Page- http://www.natures-energies.com/iching.htm New Page- http://www.natures-energies.com/index.php?option=com_content&view=article&id=760 If you type the old URL into the browser it redirects If you fetch the old URL as Googlebot in the webmaster tools the header says 301/permanently redirected. If I try to crawl as any other bot it still says 301 redirected. Even if you click the old link in Google it redirects to the new URL. Only in its cache it shows the old URL and moreover it shows the new content in it! I am stumped on how Google manages to grab the new content and puts in the old URL instead of the new one! One more interesting thing is that if I try a cache for the new page it shows the cache of the new content with old URL! Any help would be appreciated. I am at end of my wits. I think i have tried almost everything. Is there anything that I'm missing to see? You can use this search to find the old url's. Maybe you'll some patterns that i missed. site:www.natures-energies.com inurl:htm -inurl:https|index

• Restrict subversion to only allow certain functions

  - by Farseeker

  I'm in a bit of a situation. We have our private subversion server that we use for development, but one of our government clients is requesting access to our commit logs so that they can get an up-to-date picture of what we've been doing on the system. I don't have a problem with them reading our commit logs, but what I do have a problem with is them having access to our source code - they can't have read or write. The obvious solution is to do an svn log ourselves and give them an export, but they want direct SVN access as they apparently have an auditing solution that will import the svn log command automagically. So, is there a way I can set up access to a subversion repo and deny them access to everything except svn log? I don't care if I have to set up a virtualhost just for this, but it has to be done over http(s). We're also using LDAP for authentication if that makes any difference.

• Access Windows VPN DNS from Ubuntu

  - by user46427

  I am using Ubuntu 10.04 to access a Windows VPN. I connect to the VPN from Ubuntu, and when I open a Windows 7 virtual machine (VirtualBox), everything works great ... I can access local network drives, ping local servers, remote into local machines, etc. However, I can do none of this from Ubuntu. With the VPN connected, I cannot even ping anything within the VPN local network. I'm guessing it's a DNS issue that Windows is handling automatically but Ubuntu needs a setting somewhere to tell it to use the DNS servers of the VPN network? Any ideas? I'm a relative novice to Ubuntu, esp. VPN in Ubuntu. [EDIT] Actually, I'm almost positive it is DNS, because if I get the IP address from the Windows VM I can use Terminal Server Client to remote into a machine.

• What would Stack Exchange's yearly expenses be if it were to be using a third party host?

  - by abel

  StackExchange manages it's own servers, as it should, but if SE were to be hosted on a 3rd party "cloud" hosting (like Amazon's), what would it's monthly / yearly expenses be(keeping everything else the same)? A detailed answer comparing it to the bills that Stackexchange boots currently (including power/property/staff) would help. (PS: I know that the blog is a good resource. I also understand that managing your own hosting is almost the same as setting up a hosting company and using it for your own needs. Plus is this a question for meta or does it fit within serverfault's purview?)

• Different behaviour of script locally and over ssh

  - by neorg

  I have a script on a server-A Script-A #!/bin/bash -l echo "script-A.sh" | change-environment.sh When I ssh onto server-A and execute it, it works fine. However, when I ssh user@server-A ./script-A.sh Script-A executes, but throws an undefined variable error in change-environment.sh. change-environment.sh runs in the c shell(I have no control over the script so the method I have used is about the only way I can use it), but everything else is in bash. Had found a similar question at I can run a script locally, but cannot do "ssh HOSTNAME /path/to/script.sh". However, there was no solution to the issue and it was a year old.

• options for physical architecture of rails site regarding caching server or cdn

  - by timpone

  I have a rails app that is set on a single server currently. On production, I force_ssl for everything. I am interested in using a caching server for images (I'm fine with css and js being served from origin for time being). Would nginx or varnish (which I have no experience with) be a better solution (for October 2012)? I'd imagine that it would be easy to switch these around while still on this single server architecture. Or would something like cloudfront (which I also have no experience with) make sense for hosting image files? I know this is a vague question but appreciate any current feedback. thx in advance

• All HTTPS, or is it OK to accept HTTP and redirect (secure vs. user friendly)

  - by tharrison

  Our site currently redirects requests sent to http://example.com to https://example.com -- everything beyond this is served over SSL. For now, the redirect is done with an Apache rewrite rule. Our site is dealing with money, however, so security is pretty important. Does allowing HTTP in this way pose any greater security risk than just not opening or listening on port 80? Ideally, it's a little more user-friendly to redirect. (I am aware that SSL is only one of a large set of security considerations, so please make the generous assumption that we have done at least a "very good" job of covering various security bases.)

• Chrome to download Gmail attachments to a different place

  - by Joe

  I'm using Chrome and Gmail. When I download stuff from the web, Chrome automatically puts it in Downloads, which is fine. However, I'm aware that everything I download from Gmail is in the cloud anyway and so I don't really need it taking up space on my hard drive as well. Is there a way to have Gmail attachements automatically download to a different folder, say, Downloads\Gmail? That way I could regularly purge the ones that won't be useful for a while. (Yes, I'm aware that Word documents and the like often get changed after they arrive, I'm more focused on images, pdfs, and zip files.)

• Hosting solution for sensitive client data

  - by Mark

  Hello, We are developing a web application that will deal with highly sensitive (financial) data of clients (audience is medium to large sized businesses). Clients will be under scrutiny from regulators & auditors and, as such, we will be too. More importantly to give clients a level of comfort our application and related hosting arrangement should instill a lot of confidence with them. We are looking into using a cloud based service like Linode, Amazon EC2, etc. To allow for maximum flexibility We are keen on putting everything on virtual servers and avoiding having to buy our own hardware. Does a cloud based service make sense for our particular scenario? If not what type of hosting should we consider? If so what should we look out for? Thanks!

• 12.04 LTS Apache2 writing files from webpage at runtime has no effect - possible read/write permissions?

  - by J Green

  I'm running 12.04LTS with Apache and Mono in VirtualBox, with the goal of hosting a web app (coded in ASP.NET and C#) on my local network. The scripts on the page are able to successfully read from text files in the same directory as my site (/var/www/mysite/) but do not seem to be able to write. I'm sure the code works, because it did with my testing in Visual Web Developer on Windows. I don't get any errors, but when I click the button on the loaded webpage, the text file in question does not change. I'm fairly new to Linux in general, so I'm not too familiar with how to set permissions properly, and it may be a permissions issue. Unfortunately, I have searched all over the internet and haven't found a solution that worked, but I've tried (perhaps incorrectly) changing the owner of the files in question to www-root, changing the mode to a+rw, but sadly to no avail. I have tried everything here but it doesn't work: Whats the simplest way to edit and add files to "/var/www"? I hope someone can help me out.

• Best way to generate pieces in match-3 games, and then tracking them?

  - by JonLim

  I've been working on a match-3 style game in Actionscript using Flixel, and so far, I've been able to build the core mechanics of the game, including board generation, piece generation, piece swapping and movement, and checking algorithms. However, I am now running into issues with clearing out pieces and letting the above pieces fall down and generating new pieces. The reason I'm running into these issues is that when all of the pieces are generated, the pertinent values (position, sprite ID, and sprite object) are pushed into an array that helps me track everything, all the time. When pieces are moved, I swap the values of the corresponding arrays and life goes on. And that array is the core of my problem: if a row in the middle of the board clears out, ideally, all of the pieces above the cleared pieces should fall down to take their place and new pieces are generated at the top and also fall into place. Except if I try to do that now, all the pieces can fall down, but then I'd have to bump all of their values into the right arrays (oh god my head) and then generate new pieces and fit THOSE into the correct place in the array. Am I overthinking this? Or is there a far better way to track these pieces? Thanks guys!

• how to actually install PHP etc on a windows 2003 server

  - by user1624421

  We're just purchasing a dedicated windows 2003 server (in fact I think it's a VPS) How do we actually go about installing software on to it? Simply searching for "installing PHP5 on windows server" just produces material about installing it as if one had access to the computer with a keyboard and mouse. Am I being thick? I've had experience managing a linux server before but that had everything pre-configured and we accessed it via Web Hosting Manager. I don't get the actual concept of connecting to a remote PC and...downloading files? If there's any good books available please point me in the right direction.

• How can I re-program/flash a backup of the bios?

  - by user285705

  I have some computers that have a particular bios setting that keeps everything running smoothly. The setting is not the default setting for the motherboard. So, when the CMOS battery dies, the setting is erased and causes the user problems. How can I backup the bios and settings I have now, and flash that file onto my entire stock of computers? I have attempted to use awdflash to backup my bios and then attempt to write that backup to the ROM chip, but I keep getting an error. It tells me that my file number doesn't match the system, or something like that. Basically, the file is incompatible with the chip. But I just backed it up from that chip. If anyone can shed some light on this for me it would be helpful.

• Can't mount my USB Drive

  - by user996056

  ~> sudo mount /dev/sdb1 /media/Disk Did not find any restart pages in $LogFile and it was not empty. The file system wasn't safely closed on Windows. Fixing. I have a USB Hard Disk and Windows can't detect it. So I tried to open it up on Ubuntu using gparted. Gparted detects the NTFS partition, so everything seems to be fine (note, though, that the total size of the files in this disk is over 1 TB). I tried to mount it using: sudo mount /dev/sdb1 /media/Disk But I got: Did not find any restart pages in $LogFile and it was not empty. The file system wasn't safely closed on Windows. Fixing. Then, the process just sits there blinking. Any ideas on how to fix it? It's taking forever ( 10 minutes), should I wait or cancel it and do something else? Thank you in advance.

• Update-manager fails silently on 14.04

  - by pabuisson

  I recently reinstalled a lubuntu from scratch, to upgrade to 14.04. Everything's working as expected, except for the update-manager that silently fails when trying to upgrade my system's packages. It does correctly list the packages to be upgraded, I can then click on the "Install now" button (or something like this, I'm running a French flavour of Ubuntu). When I click the button, it seems unresponsive for 5 to 10 seconds, then the upgrade dialog with the progress bar appears, displays "Loading package list", then very shortly something about "authentication" (not long enough so that I can read it).. and closes. The install is fresh and I have no idea where to look. I tried launching update-manager in a term but it doesn't display any error when it fails, only this message when the window first shows up : ** (update-manager:3642): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-m0jkFlZ3yo: Connexion refusée. Any idea where this might come from ? I can upgrade the packages using the command line and sudo apt-get but this is not my computer, and I do not wish its owner to have to do this to upgrade the packages. Thanks for your help !
