• As a small business about to overhaul infrastructure and go virtual, how can we take advantage of all the features of the QNAP TS-439 Pro II+?

  - by Sally

  Specifically, how can we benefit from these current list of features? We're very new to this and I want to be able to talk intelligently to our IT consultant. VMware Ready Citrix Ready Built-in iSCSI target service Virtual Disk Drive (via iSCSI Initiator) Remote Replication Multi-LUN per Target LUN Mapping & LUN Masking Support SPC-3 Persistent Reservation Support What other products should we compare this QNAP to? I appreciate how informative the site is, but they only seem to sell their products through a small number of channels. Is QNAP well known? TIA!

• Practical tips when transitioning to xmonad?

  - by meder

  I like the idea and concept of xmonad, however I still keep going back to gnome after an hour or so. This feels like when I first tried to learn vim, but I've gotten past the learning curve point and can't live without vim nowadays. I'm sure the time will come for xmonad too, but I was wondering if current xmonad users can provide transitional tips? FYI, I'm on dual monitors ( 19 inch and 17 inch ). Example of an issue I'm having while in this "transitional" stage: How do you manage keeping the browser and other programs that are most commonly used in full screen mode, since by default I think it opens up in a small tile that takes up a portion of the screen? Do you just shortcut it to make it open full screen, or do you actually not maximize it? Or are there advanced methods through preferences in the conf file, making certain programs take up X space?

• Hosting a web site at home: ISP Blocking port 80?

  - by tombull89

  Hello, I presume this is a better place to put this rather than server fault. I'm interested in setting up a small site to host at home as a "proof of concept" exercise, i.e. to prrove that I know how to do it. I've got a (virtual) server 2003 machine with a site on it, all configured with port forwarding through to 80 on my server. I have a Belkin F5D7634 which I have put my DYNDNS details in but when I try to go to my DYNDNS address it comes up with the page cannot be displayed. My ISP is Carphone Warehouse/AOL and I've been unable to find any information if they block port 80. If they do, can anybody reccomend a home provider that does not block port 80? Regards, Tom.

• Regression testing for firewall changes

  - by James C

  We have a number of firewalls in place around our organisation and in some cases packets can pass through four levels of firewall limiting the flow TCP traffic. A concept that I'm used to from software testing is regression testing, allowing you to run a test suite against a changed application to verify that the new changes haven't affected any old features. Does anyone have any experience or an offer any solutions to being able to perform the same type of thing with firewall changes and network testing? The problem becomes a lot more complicated because you'd ideally want to be originating (and testing receipt) of packets across many machines.

• Generating my own SQL Server SSL Certificate

  - by Haoest

  I hear it's possible to make myself a test certificate with MakeCert from Windows SDK, but the beast is 1.5 GB, which I feel reluctant to download for a half-megabyte program. I do, however, have IIS Resource kit with me, which has selfssl to generate certificate for IIS. Will that work for SQL Server? Is there a more convenient way of generating myself an SSL certificate for SQL Server use? I even tried using CREATE CERTIFICATE with TSQL within SQL Server and then have it BACKUP into a file, but with no success. I must have confused the concept of certificate fundamentally. Any advice?

• keymapping when ssh-ing from mac to linux

  - by Yair

  I'm using Lion to ssh -X to a linux machine and work on some code thats located on it. I open up an editor on the remote machine (usually matlab) and program on it. My problem is that in the linux there is no concept of the command key. So if I want to copy some text from a local window to the editor that runs on the remote, I need to to command-c to copy, and then control-v to paste. This obviously drives me nuts. I was wondering if there is a way to change the keymapping such that the command key will be recognized as a control key on the remote processes. Or is this something I need to change on my local (mac) X configuration?

• Using Folder Redirection GPO and Offline Files and Folders

  - by user132844

  I want to use Folder Redirection to redirect user's My Documents to a network share. First question is: What is best practices for mapping the drive? Should I use the profile tab in AD with the %username% variable, or a net use logon script, or something else? Second question is: How do I deal with laptops and syncing the network with the local storage? I want to have 2-way syncing so if they manually map their networked home drive and edit it from a different computer, it will sync the newer version to their My Documents folder the next time they connect their normal work computer. I also want to be sure that if they edit a file offline on their laptop while away from the office, that the network version syncs the changes the next time they connect that laptop. Please advise best practices for this scenario in a 2008 R2/Win7 environment. I am also interested in Mac clients for this environment, and while I am very Mac savvy, I would like to hear what others consider to be best practices for Mac network homedirs in a Win environment.

• TCP Windows Size vs Socket Buffer Size on Windows

  - by Patrick L

  I am new to Windows networking. When people talk about TCP tuning on Windows platform, they always mention about TCP Window Size. I am wondering whether Windows uses the concept of "Socket Buffer Size"? On Windows XP, the TCP window size is fixed. We can set it using the TCPWindowSize registry value. How about Socket Buffer Size? How can we set Socket Buffer size on Windows? Can we set it to a value different from TCP window size?

• Reverse proxy using hop and RDP

  - by Sergei

  I am trying to connect from Vista to XP using RDP via reverse proxy using putty and an intermidiate host. There are myriad articles on the internet how to do it using vnc, ssh servers, winsshd, etc, but I can't find anything that helps me in this specific case. What I have: Windows XP host behind the firewall - 'destination' linux host running ssh on the internet - 'intermediate' windows host behind the firewall - 'source' All I want to do is open reverse tunnel from destination to intermidiate and use this tunnel for connecting back from the source. That should be simple to setup, however I just cannot make it. This is what I do: On 'destination', open putty session, create tunnel to 'intermediate' using following settings: source port 3389, destination is 'source:33389', direction is local On 'source', open putty session, create tunnel to 'intermediate'using following settings: source port 33389, destination is 'destination:33389', direction is local Finally, on source, open termnal services client and connect it to localhost:33389.Unfortunately it seems like packets do go somewhere but eventually client times out. Am I totally misunderstanding the concept? Please help!

• Subdomain only accessible from one computer

  - by Edan Maor

  I recently added a wildcard A record to my domain (*.root.com), mapping it to a certain elastic ip on AWS. I've configured apache to redirect all references to something.root.com to root.com, except for one specific "dev" subdomain, which is hosting its own site (a Django app, specifically). The Problem: This setup works perfectly for me on my computer. But on other computers around the office, it doesn't seem to work. Specifically, trying to visit dev.root.com gives an "unable to find server" error. Pinging dev.root.com gives a "cannot resolve hostname" error. The weird thing: pinging any other subdomain of root.com does work, from all machines. I would think this was all due to DNS propagation, except all the computers are behind the same office router, so how could that be the case? Any ideas?

• Why do LCD screens need a backlight? (seriously)

  - by Tudor

  Bare with me on this, I'm well aware that most LCDs have backlights. But what if, they DIDN'T? I spend long hours in front of a screen and I hate the concept of staring into a lightbulb all the time and my eyes getting sore. I need to get a new lcd (some sort of IPS that doesn't cost a fortune) soon, but no matter what I'll get, I'll still be looking at a damn light. How come you can read on a kindle w/o a backlight but there aren't any monitors like that? I mean, ideally, a screen should be like a book or any other object in real life. Just for curiosity's sake, does anyone know of any new monitor concepts? Also, http://www.indiaonrent.com/view/l/laptop-transparent-monitor.html hah!

• How to enable an active/active file server cluster in windows 2008 r2 Enterprise

  - by Phygg

  I've just created a cluster for my file servers in Windows 2008 R2 Ent SP1 environment. The goal - an Active/Active cluster for web server data How do I go about telling the cluster to be active for both nodes? Do I have to tell the cluster to be active/active? Here is a link to the instructions I followed when configuring the failover cluster. http://technet.microsoft.com/en-us/library/ff182326(WS.10).aspx So if anyone can help me to grasp the concept or maybe I'm way off and I need a node that is not active along with 2 active nodes to do this, I would appreciate it.

• Recommend a mail server setup for multiple domains

  - by Greg

  Hi all, I've just set up a new Debian web server which I have done plenty of times before, but I want to add a mail server which I have never done before. I am aware of this question, but I would like someone to recommend packages and briefly explain how to use them for providing pop/imap access on multiple domains, a concept that has confused me for a while. I'm planning for this server to grow slowly but surely, from serving an initial 5 or 6 domains to about 20 in the first year, continuing at this rate. (yes, I've jumped on the cloud bandwaggon). At the moment, I have a DNS-A record pointing to my server's IP and nothing else. I'm assuming that I need a DNS-MX record pointing there too, but I haven't read up about it yet so today that's what I'll be doing. Hopefully reading up on the subject and the help that I get here will get my server up and running in no time. Thanks!

• FCoE, on any Ethernet switch?

  - by javano

  I understand the concept of FCoE. I have looked at the Wikipedia page and looking at the layer 2 frame diagram, it looks like FCoE really should "just work" on any Ethernet switch, but is this really the case? If so, what do switches like Cisco's Nexus 5k or 6120P offer that normal switches don't (in specific relation to FCoE)? I am just using those two switches as examples. On the Nexus 5548UP page for example it says the following; Unified ports that support traditional Ethernet, Fibre Channel (FC),and Fibre Channel over Ethernet (FCoE) Well if FCoE runnins over regular Ethernet, that why does it support "Ethernet and Fibire Channel over Ethernet"? This is why I am curious as to weather FCoE will run on any Ethernet switch and these switches just support "bonus" features, or if you do indeed require a specialist switch. Thank you.

• How do I make a privileged port non-privileged in Redhat 5?

  - by Jason Thompson

  So I have a RedHat 5 box that I'm wanting to run an application that I wrote that implements SLP. SLP uses port 427 for answering service queries. My understanding is that ports below 1024 are "privileged" and thus cannot be bound to by anyone that's not root. I cannot run this application as root as it is launched via tomcat. One creative solution I really like was simply writing an iptables rule to route the privileged port to a non-privileged. In my proof of concept tests, this works wonderfully. Unfortunately, it would be greatly (and understandably) desired by the powers if my application did not require screwing around with iptables upon installation. So I heard a rumor and cannot find anything to verify this that there was some sort of command or parameter that could be set to make any port I want be non-privileged. Is this true? If so, how is this done? Thanks!

• Xmodmap configuration

  - by Krishna S

  On my Debian Linux machine Ctrl+Alt+F1 is bound to a virtual terminal. I can see the corresponding entry by running xmodmap -pke keycode 67 = F1 XF86_Switch_VT_1 F1 XF86_Switch_VT_1 Per this thread, which I might add is consistent with what I've read elsewhere, the columns on the right hand side of = correspond to key, Shift+key, AltGr+key and Shift+AltGr+key. Given that, I don't understand how the keycode mapping for F1 (above) works for Ctrl+Alt+F1. It seems it should really be either Shift+F1 or Shift+AltGr+F1? Here's the output of xmodmap -pm on my machine: shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x25) control Control_L (0x42), Control_R (0x69) mod1 Alt_L (0x40), Alt_R (0x6c), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb) Can anybody explain it?

• Are VLANs necessary for my environment?

  - by kleefaj

  Greetings. I'm the new network manager for a school. I've inherited an environment made up of several Windows servers, about 100 Windows clients, ten printers, one Cisco router, six Cisco switches, and 1 HP switch. Also, we're using VoIP. There are four floors in our building. The hosts on each floor are assigned to a separate VLAN. An office on the first floor has its own VLAN. All the switches are on their own VLAN. The IP phones are on their own VLAN. And the servers are on their own VLAN. For the number of hosts on the network, are all these VLANs really buying me anything? I'm new to the VLAN concept but it seems overly complicated for this environment. Or it's genius and I just don't get it. Any thoughts? Thanks, Jeff

• WAMP can connect to localhost but not 127.0.0.1

  - by Anagio

  I'm running WAMP which was working fine the other day. Today I tried connecting to 127.0.0.1 and my browser throws a 404. Both firefox and chrome. My hosts file is correct mapping 127.0.0.1 to localhost. I can telnet to both the IP and localhost port 80 and see a response from apache. When I go to localhost I see the WAMP landing page. I can go to localhost/folder and view the applications just fine. What can be causing the 404's when I go to 127.0.0.1?

• Unable to set NTFS permissions for ApplicationPoolIdentity on Windows 2008 SP2

  - by Kev

  On Windows 2008 R2 I am able to set NTFS permissions for an application pool's synthesised ApplicationPoolIdentity account thus: ICACLS d:\websites\site1\www /grant "IIS AppPool\site1":(CI)(OI)(M) The website's application pool is named site1 and is configured to run as ApplicationPoolIdentity. The site's authentication is also configured to authenticate as ApplicationPoolIdentity. I've done this a thousand times on Windows 2008 Standard Edition R2 with never a hitch. However if I try to do the same in Windows 2008 Standard Edition SP2 I get the error: IIS AppPool\site1: No mapping between account names and security IDs was done. Successfully processed 0 files; Failed processing 1 files I also notice that this fails if I try to set permissions for the application pool identity via the security GUI as well. I've seen this before and a reboot has cleared this issue but I'd like to know why this happens periodically. Googling around suggests other folks have hit this problem but there's never a satisfactory explanation. Why would this be?

• Office jukebox systems

  - by Jona

  We're looking for a good office jukebox solution where staff can select songs via a web interface to be played over the central set of speakers. Must haves: Web Interface RSS / easy to scrap display of currently playing songs Ability to play mp3s and manage an ordered playlist. Good cataloguing of media. Multiple OSs supported as clients - Windows, Mac, Fedora Linux (will probably be accomplished by virtue of a web interface). We have tried XBMC which worked well as a proof of concept however the web interface is just too immature and has too many bugs for a reliable multi-user solution. I believe the same will be true of boxee. Nice to have: Ability to play music videos onto a monitor Ability to listen to radio streams specifically Shoutcast and the BBC. Ability to run on Linux is a nice to have but windows solutions which worked well would certainly be considered. I am aware of question 61404 and don't believe this to be a duplicate due to the specific requirements.

• [Linux] Bind/map Character to alt+[some key]?

  - by Paul

  OS: Ubuntu In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+æ (Norwegian letter) to '{' system wide? Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms... :)

• How can i access windows XP remote desktop on private IP from internet?

  - by Jennie

  So the machine is behind a DSL router on a private IP so that it can not receive inbound requests. I want to know: Is there anyway to setup the router NAT (i highly doubt it supports one to one port mapping) without disturbing other users on the same router. I have another machine on internet which has public IP on it without any firewall. Can i use this machine as a relay server so that to initiate the connection, the XP machine send an outbound request and this relay server makes my connection through and then i can access my machine on pvt ip without any problem. Please tell??

• 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.

• How can I view a PDF in Firefox when the server specifies the wrong content type?

  - by Sam

  I am using Mozilla Firefox with a PDF viewer plug-in. The plug-in has been correctly associated with Adobe Reader files to view them in the browser in the settings. I would like to be able to view PDF files in Firefox rather than downloading them. This already works correctly when a web server indicates that a file has the Content-Type of application/pdf. However, some web servers provide other Content-Types for PDFs, such as application/octet-stream. (See this example of a PDF served with a non-pdf Content-Type.) I have looked at Firefox's MimeTypes.rdf file, and it appears to only support mapping applications based on file types for non-Internet-based files. How can I have Firefox view all PDF documents in-browser rather than only the ones with the application/pdf Content-Type?

• Firefox keyboard shortcuts to menu items / add-on functions

  - by Cel

  At the moment I'm using context menus a lot to access commands in Firefox, but I would like to replace this repetitive clicking and searching with keyboard shortcuts for the common tasks that I perform. How to assign keys to add-on functionality? E.g. I use Close Other Tabs from Tab Mix Plus a lot - but I could not find any add-on that allows me to create a key combination for it e.g. Ctrl Alt Shift F4? My search did yield Key config, but this extension does not allow mapping to add-on functions I thought Menu Editor might be relevant, as you can change menus with it, and re-arrange even add-on items A rather demanding solution here, which seems to require re-compiling some jar files Customizing menu shortcuts in Firefox
