• Windows 7 Firewall configuration

  - by Will Calderwood

  I had a PC set up with a VPN. I used the Windows 7 firewall to block all NON-VPN traffic to the internet, but all LAN traffic was allowed. So, with the VPN connected I could connect to all networked machines and the internet. Without the VPN connected I could only connect to the LAN and had no internet access. Unfortunately my drive failed, and I'm setting up the machine again with a replacement drive. I can't for the life of me work out how to set up the firewall again. I can easily set it up to block all NON-VPN traffic, but can't work out how to that and still allow all LAN traffic whether the VPN is connected or not. Some pointers would be useful. Thanks.

• Can I change the system's "Browse for Folder" dialog globally?

  - by Chris Phillips

  As far as I know, everyone hates the "Browse for Folder" dialog: This dialog is always too small, rarely remembers locations well, and worst of all: forces you to navigate your entire computer using a tedious tree structure. Now, to be fair, some of the problems are likely to do with how apps are invoking the control -- not setting a size or a default directory, etc. But the problem about the tedious tree control remains. Is there any way to customize your Windows installation to use a different control? Preferably an app/installer that does it for you safely, but dropping in a compatible DLL or similar technique would be okay too. Or are we stuck with this terrible control forever?

• Customer retention - why most companies have it wrong

  - by Michel Adar

  At least in the US market it is quite common for service companies to offer an initially discounted price to new customers. While this may attract new customers and robe customers from competitors, it is my argument that it is a bad strategy for the company. This strategy gives an incentive to change companies and a disincentive to stay with the company. From the point of view of the customer, after 6 months of being a customer the company rewards the loyalty by raising the price. A better strategy would be to reward customers for staying with the company. For example, by lowering the cost by 5% every year (compound discount so it does never get to zero). This is a very rational thing to do for the company. Acquiring new customers and setting up their service is expensive, new customers also tend to use more of the common resources like customer service channels. It is probably true for most companies that the cost of providing service to a customer of 10 years is lower than providing the same service in the first year of a customer's tenure. It is only logical to pass these savings to the customer. From the customer point of view, the competition would have to offer something very attractive, whether in terms of price or service, in order for the customer to switch. Such a policy would give an advantage to the first mover, but would probably force the competitors to follow suit. Overall, I would expect that this would reduce the mobility in the market, increase loyalty, increase the investment of companies in loyal customers and ultimately, increase competition for providing a better service. Competitors may even try to break the scheme by offering customers the porting of their tenure, but that would not work that well because it would disenchant existing customers and would be costly, assuming that it is costlier to serve a customer through installation and first year. What do you think? Is this better than using "save offers" to retain flip-floppers?

• Multiple SSIDs better or worse

  - by swiss196

  I'm just setting up a network in a student house with 10 rooms, 3 floors. Configuration at the moment is as follows: Virgin Media 100mb Cable Virgin SuperHub on ground floor broadcasting on SSID1 Second AP(Edimax) wired on middle floor broadcasting on SSID2 These two networks server all 3 floors fairly well but I was wondering whether it would be better to setup an individual SSID for each floor (both the routers allow me to configure up to 3 ssids on each!). Would this help with speed issues, i.e if someone on the top floor is downloading/streaming etc, this wouldn't affect someone on the middle floor on a different SSID Or, will it have no effect? Thanks, Dave

• Conditional Directory Index In Htaccess

  - by icelizard

  This relates to the question in: http://stackoverflow.com/questions/1599717/conditional-directoryindex-in-htaccess The answer states that the following should work: SetEnvIf Remote_Addr ^127\.0\.0\.0$ owner <IfDefine owner> DirectoryIndex index.html </IfDefine> <IfDefine !owner> DirectoryIndex index.php </IfDefine> I am not sure this works, the setting of the Env var deffinately does, but no matter what IP I visit the site from the DirectoryIndex is always index.php Is there something wrong with the conditional or should I be using something else? Thanks in advance

• tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

  - by ajit.george

  I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues? Thanks in advance.

• Connecting to a VirtualBox machine from the host, using an ip address

  - by Doron

  Hello, In a macbook host, I run VirtualBox having a guest ubuntu server, with a NAT network setting. In the virtual machine application "Parallels", I would get on the host an IP address of the guest, to which I could later set hostnames and access it directly. However, I couldn't find a way to accomplish this using VirtualBox. The only solution VirtualBox has for me, is to set port forwarding, and access "localhost" with these ports. How can I have the desired behavior set up, without having to change to a bridged network settings, and expose my guest computer to the network my host computer is connected to ? Thanks.

• Ubuntu 9.10 LiveCD stalls after "Install Ubuntu" selected from boot menu on eMachines

  - by nicorellius

  I am trying to install Ubuntu 9.10 from the ISO on a CD (it needs to be this version) on an eMachine with a brand new Seagate hard disk. The CD boots OK, and I choose the language. Then I am presented with the boot menu: Try Ubuntu Install Ubuntu etc I have tried the top two choices several times (trying Ubuntu and installing it), but each and every time the installation stalls and the disc stops spinning right after I hit enter after choosing the option I want. I have tried different CD/DVD drives, changing the jumpers on both CD drives, different hard drives, and nothing works. Maybe there is a BIOS setting that is choking the installation? Any help would be appreciated. Edit - I just tried running the hard drive as the master on the primary IDE and the CD drive as the slave on the primary with the same results. Maybe flash the BIOS?

• Would You Swim Laps in Lake Baikal?

  - by rickramsey

  source This is the lake where Yuli Vasiliev's countrymen swim laps. Yuli is one of my favorite OTN writers not just because he really knows his stuff. Not just because his writing is clear and accurate. And not just because his English is better than the English of most native speakers. Yo, those are all good reasons. But it's the Lake Baikal thing. Yuli recently wrote two wicked good how-to's about Oracle VM Templates. You should read them. You might gain a gram of Yuli's respect. Two grams, if you can head butt icebergs while you swim. How to Use Oracle VM Templates How to prepare an Oracle VM environment to use Oracle VM Templates, how to obtain a template, and how to deploy the template to your Oracle VM environment. Also how to create a virtual machine based on that template and how you can clone the template and change the clone's configuration. How to Use Oracle VM VirtualBox Templates How to use Oracle VM VirtualBox Templates in Oracle VM VirtualBox. Similar to the article above, but it describes how to download, install, and configure the templates within Oracle VM VirtualBox, instead of on bare metal.

• Outlook 2007 Clients attachments not opening correctly

  - by Az

  Hello, Thanks for taking the time to read this. We are having an issue on our Terminal Server clients that has me perplexed. We are running Server2003 x64 and Exchange 2007 environment. When we attempt to open an attachment for example .jpeg and the user selects to open the file, it prompts them to select a program to open the file with. The file associations apear to be fine, if I save the document to the desktop and open it, it opens with the correct program automatically. If i select "always open using this program" it will then open automatically, but I don't want to have to do this for all file types we open regularly on each client. Is this some sort of Exchange server security setting that is forcing them to associate the file? Does outlook or exchange maintain its own file association database? Thanks for reading!

I recently discovered a quirky behaviour while setting up apache web server. When i typed in my dynamic ip (http://117.254.149.11/) in the webbrowser to visit my site pages it just timed out. In terminal i tried pinging localhost and it worked. $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.063 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.044 ms But if i pinged my ip it would just time out. $ ping 117.254.149.11 PING 117.254.149.11 (117.254.149.11): 56 data bytes ^C --- 117.254.149.11 ping statistics --- 10 packets transmitted, 0 packets received, 100% packet loss Pinging any other site works though.

• Sprite transparency not effected libGDX

  - by Aon GoltzCrank

  I am making a game using libGDX and Tween Universal Engine. My problem is as follows: I have 2 screens so fars, a splash screen with the logo, and a second one which is the main menu. In the splash screen I use a SpriteBatch and a Sprite with the Texture of the image I want (which goes through some scaling.) Now I use the Tween engine, along with a created SpriteAccessor to control the alpha of the sprite. I fade the picture in, then fade it out, then change it to the next screen. In the next screen I have a single sprite, and a single, 3 slot, sprite array. In this screen I also use the tween engine, I fade the single sprite into the screen (it's the background image) then I try to, using the same method, (Tween.to) to change the alpah of the sprite array (each sprite by itself.), I first set it to 0 using Tween.set, then using the method I change it. This didn't work, after some tests I tried setting the alpha of a single sprite from the array to 0, and that didn't work. It's like the program is ignoring the alpha value, I even printed out the alpha value, it saying 0, but the sprite is visible. How can I fix this, or why might it be caused?

• OpenVPN Setup - Service Won't Start

  I'm in the process of setting up OpenVPN on a VPS running Debian 6. I've walked step-by-step through this guide twice now, and I can't get the service to start. When I start the service, the error reported in the log file is: Cannot ioctl TUNSETIFF tun: Inappropriate ioctl for device (errno=25) I've searched the web a few times and I'm not finding anything helpful. I've tried: Changing file permissions: no change Deleting the file: get an error stating no file found (errno=2) Making a folder named "tun": get an error stating no file found (errno=2) I've wiped my installation and completed the steps verbatim twice now. I get no errors along the way, just the error above within my log file. The contents of my server.conf file are listed below, minus all the comments for brevity.

• Procedural content (settlement) generation

  - by instancedName

  I have, lets say, something like a homework or assignment to do. Roughly said I need to write an algorithm (pseudo code is not necessary, just in depth description) of procedure that would generate settlements, environment and a people to populate it with, as part of some larger world generation procedure. The genre of game is not specified, it could be any genre (rpg, strategy, colony simulation etc.) where interacting with large and extensive world is central to the game. Procedure should be called once per settlement. At the time of calling, world generation procedure makes geography, culture and history input available. Output should be map of the village and it's immediate area, and various potential additional information like myths, history, demographic facts etc. Bonus would be quest ant similar stuff, but that not really my focus at the moment. I will leave quality of the output for later when I actually dig little deeper into this topic. I am free to change parameters as long as I have strong explanation for doing so. Setting of the game is undetermined so I am free to use anything that I like the most. Ok, so my actual question is: Can anyone who has some experience in this field of game design recommend me some good literature, or point me in the direction where I should look/reed/study? I'm somewhat experienced game programmer, but I've never been into game design till now so any help will be great. I want to do this assignment as good as I can. As for deadline, it's not strictly set, but lets say I don't want it to take longer then few weeks, one month at worst case.

• Slow Starting DHCP Client Service - HP Thin Clients

  - by Ryan

  We have recently began adding XPe thin clients to our domain in preperation for a new citrix environment. One thing that has been picked up on in testing is that they appear slow to boot. The issue manifest's it's self as the classic "Applying Computer Settings..." screen we are all used to seeing. After digging into the issue it appears the DHCP Client service is taking some time to load on boot, this varies but I would estimate it can take around 1 minute in some cases. I've eliminated the classic issues, DHCP is responding correctly and in quick time. DNS is not the cause and GPO's are applying promptly. A simple workaround is to assign the client a static IP which work's great so the TCP/IP servies are obviously firing up quickly, just not DHCP Client. Does anyone have any idea's on how I may be able to improve the service start time? Keen to find a better solution before I get my arm twisted into setting up 250 thin clients with static addressing!

• How to set up memcached to use unix socket?

  - by alfish

  While I could use memcached on Debian to use the default 11211 port, but I've had great difficulty setting up unix socket, Form what I'v read, I know that I need to create a memcache.socket and add -s /path/to/memcache.socket -a 0766 To /etc/memcached.conf and comment out the default connection port and IP, i.e. -p 11211 -l 127.0.0.1 However, when I restart memcached I get internal server errors on Drupal site. I'm trying to implement unix sockets to avoid TCP/IP overhead and boost overal memcached performance, however not sure how much performance gain one can expect of this tweak. I appreciate your hints or possibly configs to to resolve this.

• Detect an IP address of a Wireless Access Point device

  - by dempap

  I have a Wireless Access Point device (http://www.szedup.com/show.aspx?id=1706), which I am planning to put into BeagleBoard-xM, in order to achieve wireless communication (LAN). However, I can't find it's IP address. I mean, I have to know it's IP address in order to connect with BeagleBoard-xM via a terminal emulator. For the moment, I have this device connected via Ethernet on my router. My router's setting page shows I have this device connected, but no further information. Is there any way to find the IP address of the Wireless Access Point? I hope of being understood. Any help would be really appreciated.

• "Slave" user accounts in GNU/Linux

  - by Vi

  How to make one user account to be like root for some other user account, e.g. to be able to read, write, chmod all it's files, chown from this account to master and back, kill/ptrace all it's processes and to all thinks root can, but limited only to that particular slave account? Now I'm simulating this by allowing "master" user to "sudo -u slaveuser" and setting setfacl -dRm u:masteruser:rwx ~slaveuser. It is useful as I run most desktop programs in separate user accounts, but need to move files between them sometimes. If it requires some simple kernel patch it is OK.

• Cisco 877 as PPPoA/PPPoE bridge (no routing) - how to make it listen to IP for management?

  - by Ingmar Hupp

  I have a Cisco 877 configured to bridge ADSL with PPPoA to PPPoE on Vlan1. This works fine, but in this mode the only way I can configure the Cisco is via the serial console. I'd like to have the Cisco also listen on an IP address so I can telnet/ssh into it. I think the right way to go about this would be via bridge irb, but I'm not sure exactly how (or if that's even the right direction). IOS is 12.4T and my current config (cut down to essentials) is: no ip routing no ip cef ! ! interface ATM0 no ip address no ip route-cache no atm ilmi-keepalive pvc 0/38 encapsulation aal5snap ! dsl operating-mode auto bridge-group 1 ! ! interface Vlan1 no ip address no ip route-cache bridge-group 1 Just setting an IP address on Vlan1 didn't have the desired effect, but surely this must be possible somehow (the Draytek Vigor 120 even does it by default).

• Make a socket as a user but make it readable and writable by another

  - by user1598585

  I have a software that is run under user A, this software creates a socket in /sockets and the socket should be readable and writable by user B. I have tried setting the directory to have ownership A:A or A:B but when user A creates the socket, it ends up with uid A and gid A. Using ACLs has not helped so far, the default mask is preventing the rights to be effective. rw permisions for B will always turn into jusr r. If what I make is not a socket it will work fine. How can I best accomplish this task? (It is for a web-server where the web-application makes the socket and the web-server software forwards requests to it)

• Getting kernel errors when manually mounting VirtualBox shared folders

  - by Ross

  Updated: I've rephrased this problem as I understand it a bit more now (and have encountered another problem). I'm using a Fedora 15 guest on a Windows 7 host using VirtualBox. I am trying to mount a partition on the host PC as a shared folder for use in the guest. The folder appears in /media and is accessible when I use the auto-mount feature when setting up the shared folder, but when I attempt to mount without auto-mount I get the following error: $ sudo mount.vboxsf data /mnt/host_data /sbin/mount.vboxsf: Could not add an entry to the mount table.: Invalid argument In addition a popup appears (part of Fedora/GNOME) reporting a crash in the kernel package: WARNING: at lib/list_debug.c:26 __list_add+0x3e/0x81() However the shared folder seems to work, I can certainly browse it (although everything seems to be executable, probably down to a Windows host). Is there something wrong with what I'm doing or is this a bug (and in which case should it be reported to the Linux Kernel team or VirtualBox)?
