• How failover should work in IIS cluster with Application Request Routing?

  - by username

  I have set up several servers with IIS and connected them to the load balancer - server with installed IIS Application Request Routing. I have created a server farm and added two servers. Then I stopped IIS on the first server and tried to open my web site. It returned me an error: 502 - Web server received an invalid response while acting as a gateway or proxy server. But if instead of stopping IIS I shut down the first server, I'm getting a response from the next server which is online. The question is, what the expected behaviour should be for failover with ARR, should it switch me to the next server if IIS is stopped and server is online?

• 2 workstations won't connect to most websites, but will connect to some

  - by Dean

  I have a very frustrating issue I wasn't able to solve: 2 workstations which are used by the same user are not able to connect to most websites receivin a timeout, however they will load some websites specificly from my country. They are able to get the website addresses via DNS. Both stations have their internet connection through a remote router. Other stations in the same LAN are connecting fine. Here's what I tried: Virus scan Renewing IPs Reseting the workstations Moving one workstation to a different RJ-45 in the wall Reseting the hub and switch Checking the hosts file DNS flush Nothing seems to help. I am preparing a CD with more AV tools to see if there's anything hiding on the stations. UPDATE: It was an incorrect configuration in "Internet Options". I configured the correct proxy and now it works.

• Windows 7 RDP Fullscreen mode

  - by kubal5003

  I have a problem with remote desktop connection in Windows 7. When I connect to remote computer I would like to switch to fullscreen like I did in previous versions - just by clicking maximize. When I was in fullscreen mode and I moved the mouse to the upper border of the screen a nice bar appeared and I could minimize rdp or close it. In Windows seven when I click on the maximize button the window maximizes like a normal window - menu start/taskbar(whatever you call it) is still visible and because the resolution of the rdp client desktop is set like on the computer that I'm using it's not fully visible and scrollbars appear. That's really annoying. Can anyone tell me what to do? Is it a bug or maybe there is a "magic shortcut" that is poorly documented and does the trick? (I was trying to find it myself first ofcoz, but no result)

• Installing ubuntu server as linux distro on dell server - what drivers will be missed

  - by Cookie

  Dell (via USC) unpacks specific drivers for both RedHat and Suse to use after installation on its servers. As Ubuntu server isn't officially supported, this clearly isn't happening for Ubuntu. Is Ubuntu server then running with native drivers? In that case, which drivers are native with Ubuntu, and aren't (e.g. are Dell replaced) with RedHat/Suse? Are dell optimized drivers available for Ubuntu somewhere? Can the ones for RedHat or Suse be used with Ubuntu? Are there disadvantages of this lack of fine-tuned drivers, and if yes, what are they? Would they make the switch (and extra costs, as both RedHat and Suse Enterprise aren't cheap) away from the free Ubuntu server worthwhile? Dell recommends Canonical's commercial support for Ubuntu server on its machines, is this recommendable? Do they offer fine-tuned Dell drivers to replace native drivers?

• basic help for Nat configuration needed

  - by Klaes S.

  I have a server with a IP 1.0.0.5/24. This is the main IP address of the server, and now I have two other IP addresses for the server, they are 1.0.2.30/24 and 1.0.2.31/24. I want to make a VirtualBox running another OS accessible through the Internet, and only allow the specified IP to reach the virtual box. I'm new to iptables and therefore I need some basic help and getting started information about this. The hosting provider does not allow more than on MAC address per switch port, which means that I'm not able to make bridge as far as I know. Futhermore I want the host, to reject the extra IPs so its only the VirtualBox / virtual machine that accepts the request's on the extra IPS.

• Firestarted Blocking DHCP?

  - by Chiggins

  Alright so on my Ubuntu laptop I get a wireless internet signal, and then distribute it to a switch where my other computers are connected. I also have Firestarter installed on the laptop. I have a problem where the only way that one of my client computers try to get an IP and such from my laptop, it can't because Firestarter is blocking it somehow. I have to stop the firewall in Firestarter, then connect from a client. It connects right away, then I turn Firestarter back on. In the preferences there is an option in "Firewall" called "Start/restart firewall on DHCP lease", but if I have that checked or not doesn't make a difference. So, what can I do to fix this? Its kinda annoying to have to do this whenever I have to connect to the internet. Thanks!

• Can SBS2003 Monitoring and Reporting service work without Exchange?

  - by Magnetic_dud

  Hi, we have an SBS2003 server. Recently I decided to switch to hmailserver as i feel it's better than exchange 2003, so i disabled it. Of course i don't receive the Monitoring and Reporting emails from my server anymore, there is a way to change the setting? I think it directly interacts with Exchange, but maybe there is an smtp option out there Otherwise there is an alternative? I tried the paessler monitor on a vm, but i feel it's too much for my use: i just need to get a daily report of the security violations in the event log and something else

• Two Network Adapters on Hyper-V Host - Best way to configure?

  - by GoNorthWest

  I have two physical network adapters installed in my Hyper-V host. I want one to be dedicated to the host, and the other to provide external network services to the VMs. Would the appropriate configuration be as such: Leave the first physical network adapter alone, assigning it the host IP, but not using it to create any Virtual Netorks For the second physical adapter, I would create an External Network, along with a Microsoft Virtual Switch, and use that to provide network services to the VMs. Each virtual NIC for the VM would be associated with that External Network. A static IP would be assigned to this adapter, and each VM would be assigned a static IP as well. The above seems reasonable to me, but I'm not sure if it's correct. Does anyone have any thoughts? Thanks! Mark

• Thunderbird: Change the Format of the Date Column

  - by TheOmega

  I want to change the format of the "Date"-Column in the messagelist in Thunderbird. For mails from today, I want to display only the time, not the date. For mails from before today, I want to display only the date, not the time. This is btw the same setup mutt uses. I know of the this wiki article, which describes how to change the dateformat, but you can only switch between 5 predefined formats, and non of them is "Date only". I also know of this Extension, but it got the same limitations, you can't define a new date format. Thanks!

• DVI problem with LG L204WT

  - by Holgerwa

  I have a LG L204WT which has VGA and DVI connectors. Until recently, I have used the monitor via VGA, but now I have upgraded the graphics board and switched to DVI. The problem is that each time after the computer starts, the monitor either doesn't show anything (black screen, but doesn't go into standby) or the picture is distorted. I then switch the monitor off and on several times, and at some point it starts correctly and then I can work as usual. This only happens on startup. It is one out of 3 monitors, the other two work fine. It seems to me as if the monitor is not able to synchronize on the DVI signal and either shows a distorted picture or nothing at all. There are no settings in the monitor setup that would change anything. What could be the problem?

• ZFS on top of iSCSI

  - by Solipsism

  I'm planning on building out a file server using ZFS and BSD, and I was hoping to make it more expandable by attaching drives stored in other machines in the same rack via iSCSI (e.g., one machine is running ZFS, and others have iSCSI targets available to be connected to by the ZFS box and added to zpools). Looking for other people who have tried this has pretty much lead me to resources about exposing iSCSI shares on top of ZFS, but nothing about the reverse. Primarily I have the following questions: Is iSCSI over gigabit ethernet fast enough for this purpose, or would I have to switch to 10GbE to get decent performance? What would happen when one of the machines running iSCSI targets disconnects from the network? Is there a better way to do this that I just am not clever enough to have realized? Thanks for any help.

• Remotely enter encryption key?

  - by Jason Swett

  This might be a really dumb question but here goes, anyway. I just bought a couple servers. I already installed Ubuntu with encrypted LVM on one and I'm planning on doing the same with the other. This means that every time I boot up each of these machines, I have to enter the passphrase. And I'll have to do this every morning because I'll power each machine off each night for security reasons. Here's the problem: I don't have monitors or keyboards for these servers. It seems to me I have two options: Somehow enter the passphrase remotely Buy a KVM switch I doubt #1 is an option but I want to make sure it's not before I buy a KVM. Is it possible to enter the passphrase remotely? AND is it a good idea?

• If the WiFi switched on, should it disable the ethernet? [closed]

  - by Peter Stuart

  My friend having problems with her laptop and I am trying to help her via SMS. She can't get her laptop connected to the internet via the Ethernet connection and there is no WiFi in the area. Could it be because her WiFi is switch on, she is using an acer aspire. If she manually switches it off could that allow the ethernet connecttion to work? Or is it a missing driver? The cable works fine as her someone else tried it. Thanks Peter

• what's POST code 18 / can I run an ASRock P55 Pro + Core i3 530?

  - by Michael Borgwardt

  When I switch my newly built PC on, the fans start up, but I get nothing on the monitor, and the POST display on the motherboard runs quickly through various codes and then stops at code 18, which does not appear in the manual (the list there seems identical to this one). This lasts about 10 seconds, after which the machine shuts down. After a pause (also about 10 seconds) it starts up again, and this repeats until I cut the power. Interestingly, when I push the reset button, it stops at POST code 16 (which is also not listed in the manual). Does anyone have information about the meaning of those codes? Motherboard: ASRock P55 Pro CPU: Intel Core i3 530 Graphics Card: Sapphire HHD 5750 Does anyone have experience with that Motherboard/CPU combination? It says on the packaging and in the manual that it's only compatible with Core i5 and i7 (no mention of i3), but on the maker's product page, the i3 is listed as compatible as well.

• Cross platform KVM over ethernet

  - by Falmarri

  I'm not sure if this exists, but this is what I'd like to do. I have a laptop and a desktop that I work on about equally. The laptop runs windows 7 and the desktop is on kubuntu 10.04. What I want to be able to do is be able to drag my mouse accross my screen and have it act like my laptop is a second monitor. Whereby I can use my desktop mouse, drag it say to the left off of my desktop monitor, and use it on my laptop (I don't care about the keyboard, just the mouse). Is that possible? Are there any other solutions that exist? I'd prefer not to have a physical kvm switch.

• Tool to allow Kerberos Authenticated users to modify Firewall settings

  - by Lars Hanke

  I run a firewall on a central router. Recently, several users want to use Skype. Since firewalling Skype virtually means to switch the firewall off, I consider to allow users to temporarily punch holes for their system. Since the users have no accounts on the router, I consider using Kerberos for authentication and authorization. The router is a Debian Squeeze box, with minimal configuration, i.e. no web-server, database or similar gimmicks. Does anyone know an existing solution, which could be used for that purpose? Or does anybody know easy to use and well documented frameworks in say Perl, Python, C, C++, ... making the set-up of a Kerberos authenticated Client and Server application really simple?

• What should I know before considering a VPS or dedicated server?

  - by Corey Sarnia

  I have a plan for the future for an application and web service. The client will have an application that will send requests to a server-side Java back-end that will process requests, and the server should also be able to host a website, preferably on a WAMP setup (which is what I'm used to; very little *nix knowledge). Now, I cannot provide any hard stats because this is only a plan that's in a discussion stage. However, we do fully expect it will scale enough to need some type of dedicated hosting. My question is this: what types of things should I know about before looking into getting hosting? What should I be asking the hosting providers before I decide on a purchase? When is it appropriate to switch from a VPS to a fully dedicated server?

• Disable CTRL + ALT + [LETTER] to produce accented variations

  - by Barney

  After an unknown config change, CTRL + ALT + [LETTER] has started producing common accented versions of [LETTER]. I'm not a big fan of this arrangement, seeing as I've memorized all my favourite ALT + [NUMPAD SEQUENCE] references and was used to using CTRL + ALT + [LETTER] for various other application-specific commands in my text editor. The prominent result from my searching suggests that this has something to do with a switch to an 'international keyboard', and says this can be removed in the control panel or toggled by hitting ALT + SHIFT, but I can't get my system to confirm this, and the solutions (or close approximations thereof) don't work. Specifically, I've been to Control Panel\Clock, Language, and Region\Language\Advanced settings and switched the override for default input method from 'language list' to English and I've been to Control Panel\Clock, Language, and Region\Language\Language options and made sure that I only have my one input method (UK). Other than that I'm not quite sure where to look. Any ideas?

• Can I make Windows behave like an ethernet hub?

  - by dromedary

  I have two machines A and C mutually connected to NICs on a third machine, B, as follows: A-B-C B is a Windows 7 machine configured with a bridge containing the A-B and B-C NICs, so that A and C can communicate. So far, so good. I need frames from A destined for B to also arrive at C. Essentially, I would like Windows to behave like a hub rather than a switch. Is there any way to do this? If you have any ideas at all, no matter how hacky or roundabout, I would love to hear from you! I have been tearing my hair out over this and by now I am willing to try anything. My only limitations are that I can't touch A or change to a different operating system on B.

• Amazon EC2 Sign In

  - by Barry

  When I change the home directory of my Amazon EC2 instance from /home/ubuntu to /home/ubuntu/folder in the /etc/passwd file, I am no longer able to access the instance using my existing keypair. Once I switch it back to the original directory I have no problems and can log into my instance as normal. I have checked the permissions on the new folder and they are drwxr-xr-x, which is the same the /home/ubuntu folder. I have a number of instances running at the minute and because of this change I have no way of logging back into them to rectify the situation. Does anyone have an idea what is going on? Thanks in advance

• Moving software RAID to Linux

  - by terman

  I'm using a RAID 1 (mirrored pair) configuration in my Media Center/ NAS system. Currently it's running Windows 8 (yeah, big mistake I know) and I'm regretting it (did it for the games, not worth it). Currently I'm having two software RAID 1s (3TB + 2TB) configured with Storage Spaces and unfortunately formatted with NTFS. Now I would like to switch to Fedora (or maybe Ubuntu if there are advantages) for good. Is there a way that I could continue using the disks as they are without the need to format them with ext or something? I'm glad for every tip. Oh, the system disk is of cause not in a raid configuration.

• With Bash + iTerm2, how to name tabs?

  - by Problemaniac

  In iTerm2 (Build 1.0.0.20120203), I typically open several tabs, each of which has split panes , and is about one particular theme of work, for example revision control, coding, managing files, mysql terminal work. I typically need to switch between 5 or more tabs in my work flow. It is sometimes hard to remember or tell which is which by looking at the content of the screen. I'd like to name the tabs somehow, so I can quickly tell which is which by quickly glancing. Is this possible?

• ALT+TAB doesn't work properly in Windows 8.1

  - by Marco1

  Holding ALT+TAB will activate the flip 2D to switch from a window to another. The problem is that this function remains active for a very short time and I'm not able to select the window I want in the foreground. I also noticed that when I put the cursor on an icon on the taskbar, the live preview thumbnail disappears quickly. With a safe mode restart the problem is no longer there, all is fine! With a clean install of Windows 8.1(no driver and applications installed) the problem is here again; obviously disappears with a safe mode restart also in this situation. What's the problem? A Windows process or service?

• Migrating from Desktop PC to real Server

  - by tevlon84

  i am a student, working as a part-time Administrator at a startup. I never ever used a real Server ( only a Desktop Pc with apache ) The Company i am working for is growing and they want to switch to a real Server. My idea would be to use the Ubuntu build-in Backup function and use this Backup file as Base for the Rack-Server, but i don't know, which problems i would run into. Is it a good idea ? So basically my question is : *What is the easiest way to migrate from a Desktop PC to a real Rack-Server? ( on an Ubuntu Server) *

• Prevent Virtualbox intercepting certain key combinations?

  - by Blazemore

  Is it possible to prevent my Windows 7 guest OS intercepting Ctrl+Up/Down, and allow my Ubuntu how to intercept them instead? I have a dual-monitor setup with two vertical virtual desktops on Ubuntu. I have a Windows 7 fullscreen guest on one monitor, set to always display on the current workspace. This means I have effectively two vertical workspaces on one monitor, and just Windows 7 on the other. The problem occurs with Windows 7 is focussed and I hit Ctrl+Up/Down to switch workspaces. I have to click out of the VM first, which breaks my workflow. Can this be fixed?
