• Can I run ubuntu server 64 bit in a VirtualBox on a macbook host ?

  - by Doron

  Hello, I have a macbook pro with Intel Core 2 Due (It's actually not Pro, but it's a January 2009 unibody macbook - when there were both a unibody macbook, and a unibody macbook pro). I'm a php developer. I just installed a new hard drive, and in an effort to create a better development environment, I decided I'll try to create a virtual machine running ubuntu server. Since I need it to work fast (and since, well - it's just better, even if by a little) and I'll already have a delay due to the nature of the apache server being on a virtual host - I want to install a 64 bit version of ubuntu server. Can VirtualBox handle it? Is it s good idea to create such a development environment ? Thank you.

• Cannot open any web page, but MSN Messenger works

  - by Steven

  I use my computer behind a router. My MSN program can connect to the Internet, but I can not open any web site with my web browser. It seems that this problem is related to DNS because when I input an IP address directly in the address bar of my web browser, the web page can be displayed. However, I don't know how to fix this problem. I choose Google Public DNS server on my computer, this problem still exists. My OS is windows XP. How to fix this problem? Any ideas?

• Proxying fake domain to a localhost port

  - by Trevor Burnham

  I'd like to do much the same thing described at Redirect Domain Name to Localhost for web app development purposes, but with the twist that I'd like requests to fakedomain.com:80 to be routed to localhost:8080, say, so that I don't have to actually use my development machine's port 80. I'd welcome answers that take the form of: Small changes to configuration files like /etc/hosts, and/or An easy-to-configure proxy server I could run Note: Pow takes the approach of setting a firewall rule to forward all incoming traffic on port 80 to port 20559. That may be an acceptable solution, but ideally, I'd like to forward only a specific domain + port combination.

• Amount of RAM for a web-server user.

  - by Janis Peisenieks

  I'm curently hosting my clients web-sites on some vps servers. What I would like to know, how many visitors can use the multiple web sites concurrently, before I need to migrate each of the sites to their seperate servers? So in laymans terms, how much RAM does a web-page user take on average? For example, how many concurrent visitors can I have on my server, running an Apache server, with 512mb RAM?

• Forgot password to development database

  - by ninja08

  I've created a database using terminal while following along with a tutorial. Although I had a lot of trouble getting the databases to install. Now after finally getting it to work I changed a few things, actually just the name of the database using the rake command to just "next". The password should be 'secret password'. How can I change the password or find out what it is or change it? It doesn't seem to be edited my databases.yml file with the password, especially since it still just says 'root' as username with now password in there.

• Cinema4D for game development tutorials anyone ?

  - by George Profenza

  Hi, I started to learn Cinema 4D. I've noticed it's really easy to use for motion graphics, but I want to use it for modeling for games/realtime 3d engines. Before I used 3dsmax and it was easy to estimate how a model would look/behave in a 3d engine. The two main things I did was displaying Polygon triangles and displaying the Polygon Count. I've found the Total Polygons tick in HUD settings in Cinema 4D, but I can't find any display mode that will show triangles. Is there there a way to display triangle faces/not quads in Cinema4D ? If so how ? There is a Triangulate function, but I'd rather not Triangulate/Untriangulate all the time, especially since it's converting back and forth between the two doesn't always produce the same result.

• Authentication between web server and sql server

  - by thirster42

  So, we're restructuring out development environment. We've installed SQL Server onto it's own server, and we are publishing our internal web applications onto a seperate web server. However, the problem is that for some reason the authentication of the user between the web server and sql server gets lost, resulting in the Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON' error. Where do i start troubleshooting? SQL Server is set up for TCP and remote connections.

• What does "Application Server" in Windows Server 2008 mean?

  - by In Sane

  When seeing the Windows Server 2008 R2 edition comparision by Role, i noticed that there is an entry for Application Server separate from that of IIS. http://www.microsoft.com/windowsserver2008/en/us/r2-compare-roles.aspx What is confusing me is that for Web edition, "Application Server" is not ticked but IIS is ticked. Isnt IIS both the web server and the application server in Windows? And if so, if i take the web edition, can i not host my business components (WCF services)on it because it is not an "Application Server" ?

• Setting external IP for Citrix Web Interface

  - by Callum Jones

  I have a Citrix Web Interface (as part of XenApp 6.0 on Windows Server 2008 R2) that is behind a NAT, I can access the web interface fine (via both SSL and standard port 80) but when I go to launch a application that connection is still being made over the server's internal IP address. How do I configure the web interface to default to the external IP address of the box instead of its internal LAN IP?

• How can I make outbound requests from two servers that appear to come from the same IP address

  - by Brad

  I am making calls from an ec2 instance to a third party web service (over which I have no control). I would like to be able to scale horizontally, so that I can make these calls from multiple ec2 instances, but the web service I'm calling whitelists my IP, and for the sake of discussion let's assume I can't get another IP address whitelisted. How can I send requests from 2+ machines that appear to the web service to be from the same IP address? Thanks!

• Unable to map to web folder using WebDAV client on Windows Server 2008 R2

  - by user74989

  Hello, I have a client running Windows Server 2008 R2 on several servers. One of the servers is also running SharePoint 3.0 and my client has created a web folder to map to. I can map to the web folder from all Server 2008 R2 boxes that have the WebDAV client (part of Desktop Experience feature) installed, except for the server the folder resides on. When I attempt to map to the web folder on the server which the folder resides, I am repeatedly prompted to enter my credentials. I am using the same account that I used to map the web folder on the other servers. I have also tried mapping from the command line and receive 'Access Denied' What may be causing the problem? I would think that if I can map to the drive from one server, I should be able to map the drive from the rest as long as the WebDAV client is installed, especially on the server where the folder is located.

• IIS 7 Web service access

  - by Aharon Manne

  I am trying to debug a simple web service. I have IIS 7 installed on my development machine (Windows 7), and have installed the web service. I can access it from my development machine, but not from any other machine in the local network.I opened the firewall to HTTP access, and I can access the default website from other machines, so it is not the firewall.What security settings should I look at to try to allow devices on the LAN to access the web service?

• Web Filter For Multiple Networks

  - by Rob

  I have been using a Barracuda web filter 310 in our network and I have just had enough of it. It does not support trunking and we have several networks that have users that need to be web filtered. (I guess if everyone just did their flippin jobs I would not have this issue) but the management wants me to get it resolved. Does anyone know the top five web filters that are better than the barracuda web filters that support network trunking so that I can have multiple domains and subnets going through it? Thanks in advance - everyone on this site is gold in my book!

• How do I turn off caching in IIS7?

  - by jammus

  Hello. I'm developing an ASP classic site under Windows 7 (form a queue ladies). The problem is IIS seems to be heavily making use of its cache for both static and dynamic content which really conflicts with my 'make a small change, alt-tab, hit ctrl-F5' development style. Changes made to .asp files may take two or three refreshes to show up where as changes to .js files can take 20 times as many. How do I go about turning the caching off on my development machine? Cheers. in b4 stop using asp classic

• Reverse proxy for mailserver (SMTP + HTTP for web client)

  - by ba

  I'm looking at doing some reverse proxy work for a mail server with corresponding web client. Both servers are running on the same machine, this is not a server with a high load. :) The solution I've discussed with friends is having the mail server/web client on our internal network. Then to put a reverse proxy on the DMZ to service both SMTP and web client HTTP-traffic to the mail server on the internal network. From what I understand this is the recommended secure solution? So far I've thought for the SMTP-proxy part of using postfix which will receive mail, do some spamhause and similar anti-spam measures and if it all checks out, send the mail to the mail server on the inside. The mail server on the inside will send all outgoing mail to the proxy which will then send it out on the Internet. For the web client I'm not sure exactly which software I should be running on the proxy machine, I've been thinking about using Squid -- but that's basically based on the fact that I know squid is a http proxy. The web client data will be sent out over SSL. Reading around some here on Serverfault I've seen other people using Apache with mod_proxy+mod_security for similar situations. Am I thinking correctly for this solution? What software would you guys use and with which modules? Thanks in advance for the help! :)

• Java Development in Linux

  - by Zac

  I'm a developer and am brand new to Linux (Ubuntu): I'm wondering what the "best practices dictate" for what FHS directories to install various tools to. Things I'll be installing: Eclipse & plugins GlassFish SVN ...etc. I see that /opt is for holding additional ("optional") software packages, but also see /usr as a place for utils and apps. In another post a user recommended I create an entire partition for /srv alone, and to do my staging there (I assume he meant that /srv is where GlassFish and other servers should go?). So basically: what FHS directories do Linux developers use for which type of tools? Thanks for any input here

• What's the typical latency for key strokes using an ssh connection on a local wifi network?

  - by dan

  I develop software on a Macbook Air 1.6 Ghz but find running Rails test suites and generators on this computer very slow. I'm thinking about buying a Linux tower to put on my local wireless network to do my Rails development on. I would want to use my Macbook Air and ssh into the Linux box and do my development with Gnu Screen, vim, etc. Can I expect the keystroke and echo latency for a ssh session between two machines on a local wireless network to be negligible? Does anyone develop using this kind of local setup?

• How to redirect external web request to localhost's testing server

  - by Ivan Monteiro

  Some web services calls my web application(www.myapplication.com/external_update_handler). I need to test those requests locally, so I'd like to know your opinions about how can I "redirect" those requests to my localhost dev machine(that is outside of my web aplication domain) so I can debug. Probably it's needed a service/server to get those external requests and a desktop application that sends it to localhost:5555/external_update_handler, but I have no idea where to start and simpler options.

• Visual Studio Development on Virtual Box, Boot Camp, or VMWare Fusion

  - by Eli

  I currently have a Mac, 2ghz and 2 gigs of ram, running OS X Leopard and Virtual Box with a Windows 7 Pro 32bit virtual machine. Performance on the virtual machine is fine for minor tasks but is very clunky while trying to multi-task or develop in Visual Studio 2008. What would be my best option for being able to use Visual Studio, keeping cost and time in mind? 1) Upgrade ram to 4 gigs ($100). Will this really improve my performance enough to use Visual Studio in a Windows 7 vm? Or am I just wasting time/money? 2) Reinstall/restore Windows 7 disk image as a Boot Camp partition. I assume this should improve my performance, yes? 3) Purchase VMWare fusion instead of VirtualBox. Does Fusion require less resources to run? I am open to any suggestions. Thanks in advance
