• IIS Reverse Proxy support for multiple protocols

  - by Abraxas

  I have a server 2012 machine running IIS. It's in my DMZ and I would like to use it to do reverse proxy for several services. I can get it to route traffic on port 80 to 2 separate internal servers running web apps but there are some issues when I try to forward SSH (not port 80/443) and then when I try to forward OWA (Micrsoft exchange's 'webmail' services) to the internal mail server I run in to issues with guides (like this: http://blogs.technet.com/b/exchange/archive/2013/07/19/reverse-proxy-for-exchange-server-2013-using-iis-arr-part-1.aspx) when they say to have all traffic forwarded to the server farm created for OWA. My question for you all is this - given that there is no more Threat Management Gateway (only runs on server 2008) and ISA 2006 is also dead - is it possible to support multiple types of reverse proxies with different protocols (ftp, ssh, web, ssl-web) in IIS, or would it be better to install a different DMZ OS like a nginx server and use linux firewalls + nginx reverse proxy? Thanks for any help!

• Thunderbird gives " Not enough disk space " alert, after trying to download more emails ( Win 7, 64 bit )

  - by James C

  So, today I have installed Mozilla Thunderbird 24.2.0 on my Windows 7 (64 bit) machine. It was downloading emails, until it hit an error. An alert showed up saying : "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." Now, disk space is not a problem, there is enough free space left ( almost 50 % of the drive ). How to stop the alert and continue downloading ?

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• Why does PsExec hang after successfully running a powershell script?

  - by Matt

  The script is fairly straight forward. Simply tries to start a bunch of windows services. Execution locally works fine when on the target machine. The script is actually executing fine as well when done via PsExec, it just never returns until I hit the "enter" key on my CMD prompt. This is a problem, because this is being called from TeamCity, and it makes the Agent hang waiting for PsExec to return. I've tried the following: Adding an exit and exit 0 at the end of the Powershell script Adding a < NUL to the end of the PsExec call, per the answer in this SF question Adding a > stdout redirect This is how I am actually calling psexec: psexec \\target -u domain\username -p password powershell c:\path\script.ps1 No matter what I do, it hangs until I the locally on the cmd prompt. After I hit enter, I get the message: powershell exited on target with error code 0.

• File not updating in symlink'd folder in IIS

  - by Daniel Short

  I have the following setup: Site1/Shared/ - Physical folder Site2/Shared/ - symlink using mklink to Site1/Shared I've updated a javascript file in Site1/Shared/scripts, and the change is being reflected on Site1. However, the change is not being reflected through IIS on Site2. When I open Site1/Shared/scripts/common.js and Site2/Shared/scripts/common.js, they match exactly. But when I view the files through Safari, Firefox, Chrome, IE, from any machine (even machines that have never visited the sites), the change is not reflected on Site2. Here are URLs to the files to review: Site 1: http://www.landsofamerica.com/shared/scripts/common.js Site 2: http://www.landsoftexas.com/shared/scripts/common.js These files look exactly the same when logged onto the server, and the shared folder under landsoftexas.com is a symlink created using mklink to the shared folder under landsofamerica.com. Any idea what might be causing IIS to serve the wrong file?

  - by michale

  We have a Main application named "Trevor" installed in 2008R2 machine named "TEAMER12" which is slow now. One more application named "TVS" also running in and found there were many connections per second occurring to port 5009. netstat tool mentions that some fast connection open/close seen for port 5009 So first it will be listening mode like shown below TCP 0.0.0.0:5009 TEAMER12:0 LISTENING then establishes connection like TCP 127.0.0.1:5009 TEAMER12:49519 ESTABLISHED TCP 127.0.0.1:5009 TEAMER12:60903 ESTABLISHED After that iwill become TIME_WAIT and i could see several entries like shown below TCP 127.0.0.1:49156 TEAMER12:5009 TIME_WAIT after that it will establish connection like TCP 127.0.0.1:60903 TEAMER12:5009 ESTABLISHED TCP 127.0.0.1:64181 TEAMER12:microsoft-ds ESTABLISHED again it will go several entries like TIME_WAIT TCP 127.0.0.1:49156 TEAMER12:5009 TIME_WAIT Finally it will establish like this TCP 172.26.127.40:139 TEAMER12:0 LISTENING TCP 172.26.127.42:139 TEAMER12:0 LISTENING TCP 172.26.127.42:5009 TEAMER12:64445 ESTABLISHED TCP 172.26.127.42:64445 TEAMER12:5009 ESTABLISHED Can any body tell me whats the reason behind why many connections per second occurring to port 5009 and why application slow?

• Has anyone managed to install Office Webapps on SharePoint 2010, on Windows 7 ?

  - by Nick Haslam

  I've installed SharePoint 2010 as a development environment on my Windows 7 x64 environment (notes here) and would like to install Office Web Apps onto it also. However, when trying to install (following this link), I get an error saying that Web roles aren't installed. The error message in the log file is: Start C:\Windows\system32\ServerManagerCmd.exe -whatif -inputpath C:\Users\nickh\AppData\Local\Temp\PRE1.tmp.XML Error: Failed to start process for file: C:\Windows\system32\ServerManagerCmd.exe arguments: -whatif -inputpath C:\Users\nickh\AppData\Local\Temp\PRE1.tmp.XML ErrorCode: 2(0x2). Which is effectively saying that ServerManagerCmd is not found. It isn't on my machine as it is deprecated and replaced by Powershell functions, but is on Server 2008 R2. I've tried copying that over and it just fails to run. Is there a way to get Office WebApps installed on Win7 ? Is there a way to get a working version of ServerManagerCmd.exe on a Windows 7 x64 environment ? Many thanks

• Is it possible to save the product key of Windows 8?

  - by Dibya Ranjan

  I have Windows 8 activated in my system. I don't have the product key of windows right now. Now I want to format my system again. Is there any way so that I can reuse the key? Is there any way I can get the key from an activated windows machine? Edit: I am not able to find the product key because I have used a MAK as my product key. Now I want the same to use it after formatting my disk. I found a software Volume Activation Manager tool on the windows website. I am not sure how to use it. Please tell me how can I reuse my key?

• Sync iPhone applications in iTunes

  - by Uwe Honekamp

  Suppose I have one the one hand one iTunes library on a PC used to sync Outlook contacts and calendar plus on the other hand one iTunes library on a Mac that syncs music, podcasts, apps, ringtones, etc. Both libraries are based on iTunes 9.0.2. It turns out that the iTunes library on the PC always tries to sync apps and ringtones as well. Unfortunately, this boils down to deleting apps and ringtones from the iPhone because the apps are not part of the iTunes library on the PC. After unchecking the checkbox to sync apps and ringtones and plugging the iPhone into the Mac the checkbox is also unchecked on the Mac. It seems as if the settings for syncing apps and ringtones are stored on the iPhone rather than in the particular iTunes library. Whenever syncing apps and ringtones is active on one machine it is also active on the other and vice versa. How can I make the PC ignore apps and ringtones and only sync contacts and calendar?

• SSD install - what do I need to watch out for when reconfiguring SATA ports?

  - by tim11g

  I installed a Samsung 840 SSD in a Windows 7 machine. It seems to be working fine, but I'm not seeing the expected performance. The AS SSD benchmark gives 76 for read and 138 for write. At the upper left of the benchmark it says "pciide - BAD" and "31K - BAD". I'm assuming the "pciide BAD" means the motherboard (Gigabyte GA-P35-DS4) is configured as IDE emulation and needs to change to native SATA. I don't know what the "31K" refers to. The bios settings look like this: I saw this article that indicates that changing the SATA mode of the boot drive can cause problems (Blue Screen): Error message occurs after you change the SATA mode of the boot drive What is the correct procedure to change the SATA Mode without causing a system failure? Apply the registry change from the MSFT article above first, then reboot and change the SATA mode? Will the SATA mode change in the BIOS affect other drives?

• putty pageant - forget keys after period of inactivity

  - by pQd

  in the environment where windows client computers are used to run putty to connect to multiple linux servers i'm considering moving away from password based authentication and using public/private key pairs with pass-phrases. using ssh-agent would be nice, but at the same time i'd like it to 'forget' the pass-phrases after given period of inactivity. it seems that putty's pageant does not provide such feature; what would you suggest as alternative? solutions that i'm considering: patching pageant code [might be tricky, code is probably quite rusty and project - sadly - stagnant] writing small custom application using GetLastInputInfo and killing pageant if the machine was idle for more than let's say 15 minutes [ yes, there'll be separate policy for locking the desktops as well ] using alternative ssh client and ssh agent. any suggestions? thanks!

• Computer prints blank pages before and after content

  - by Cpt. Jack

  This would seem like a pretty simple question but I have exhausted every idea I can come up with. I bought a brand new Dell Latitude E5410 not too long ago with Windows 7 OS. I installed office 2010 on the machine right away and have had a printing problem since day one. For some reason every time I print a page, a blank page prints out before and after the content print. This also applies to any other application such as notepad or printing an email. If I have a 6 page document, it still prints out one page before and after every content page. Meaning I get my 6 page document along with 12 blank pages. I can't figure out why this would be some sort of default setting or what would cause this printing configuration. I am the only computer on the network that has this problem and quite frankly I'm getting tired of it. Can anyone help me figure this out or steer me in the right direction to correcting this problem?

• About online game servers and how to handle data

  - by TreantBG

  So my question isn't about what technology to use or how to do this or that, but a more general question. I'm currently developing a action third person shooter. With elements of RPG - weapon,armor upgrades and items. Players will be able to create new games or join old ones. So my question is how to create the game server that players will play in. I have two ideas on my mind. The player who made the game is the server. All data passes trough him and he send this data to the server updating the database of the players with their XP points kills/deaths score and other. Or my host machine is the server, the player who made the game just will open new instance on my host and will be like client. And all players send their input data to the host, the host updates the game and send response back to client for any new changes like where is the enemy and other. And if i choose option 1 is there a chance the host to change the game content and manipulate the game results? (I think there is but i'm not sure) And if i choose option 2 isn't that raising the response time and potentially the game lag? or maybe there is another option?

• What is causing a vm to exhibit packet loss?

  - by Joe Philllips

  We have a pretty nice piece of hardware set up to run multiple virtual machines in vmware and one of the vm's is an instance of Windows Server 2003 running SQL Server 2005. For some reason we occasionally see 10-20 seconds of straight packet loss to this machine from remote machines (my workstation) as well as other vm's on the same physical hardware. I am using PingPlotter to keep a close eye on the packet loss. So far we've turned off flow control on the NIC but we are already running out of other things to try. What might be causing this and how can I identify the problem? Note: We also have another server with a very similar configuration with the same type of problem to a lesser extent (because its not used as heavily?)

• Environment variables in Weblogic Managed Server with SSL nodemanager

  - by Eric Darchis

  We have a C legacy application start with JNI that requires environment variables. Not java -Djava.library.path -Dvar=foo as these are purely java. I need real environment variables. When we setup our domains, we usually use the SSH method to start the node managers. This works fine and the env variables are set properly. Recently the sysadmin has decided for a few reasons to use the SSL mode for nodemanagers. The servers start but the environment variables are not set. I checked with "pargs -e" (this is a Solaris machine) that the env variable was indeed not present from the nodemanager and for the managed server. Is SSL starting the managed server without running the .sh scripts or I am missing a parameter somewhere ?

• Video Streaming in Windows 7

  - by Adam Haile

  I just got Windows 7 up and running, and I turned on the new media streaming feature and added all of my music and videos to the corresponding libraries on my machine. I can then go to my XBox 360 and pull up my entire music collection with no problem, but when I try to find the videos it says there are none. Now, I DID NOT import any of the music or videos into Windows Media Player...I know you used to have to stream things this way. But why does it work with Music and not with Videos?? They are all in formats that I know both Windows 7 and the Xbox can play as well...I used to use TVersity and didn't have to even transcode the files to play them.

• SCCM deploy from VMware XP image

  - by HannesFostie

  We recently set up the latest version of SCCM and I managed to capture a .wim image from a virtual machine (build and capture task sequence). I want to use this .wim file to deploy winXP to different hardware, and therefor need to add device drivers to the task sequence. I created a driver package per laptop type, and deployed for the first time. However, I am getting a BSOD (0x00007B) which leads me to believe theres a problem with the storage drivers. After adjusting the task sequence to try and point to the mass storage drivers (which are applied at F6, I suppose) I do not get a list of compatible drivers (the list is empty). I looked around, and found some issues regarding hdc class drivers that are not recognized as mass storage drivers. The workaround suggested changing the INF file to make the driver a SCSIAdapter class driver, and importing these again, but to no avail. The list remains empty. Any help is much appreciated

• crippling repeating "pciehp card not present" notifications

  - by Nanne

  When using ubuntu (12.04, both installed and on a live usb) I get a lot of these messages: pciehp 0000:00:1c.5:pcie04: Card not present on Slot(37) pciehp 0000:00:1c.5:pcie04: Card present on Slot(37) And with a lot I mean about 20 per second. This has a crippling effect, and I would like to get rid of it :) The computer is a packard bell easynote BG48-U-100 DC. I tip I picked up from some fedora/redhat error here was to look at lspci -vnn. I have pasted the part about "00:1c.5" here: http://pastebin.com/0sfsiqW2 For what good it may do, here is the lsmod of my machine: http://pastebin.com/DQZy1kAL From that first pastebin I think to conclude that it has to do with the module shpchp, which seems to me (aka: google) to have something to do with ACPI. That's as far as I've come in disecting this. Can anyone help me along further? What can I do, check etc? I did see this topic but my intentions are not to surpress the error message: I know how to do this (from that topic ;) ), but I'm looking for a real sollution. Finding the problem on the internet does suspect me to believe it is neither an ubuntu specific nor a packard-bell specific problem.If you google the problem it seems that is present on several other distribution/hardware combo's as well, and it looks like the advice is to remove one of the drivers? I have no clue as to which driver I should look at and and what would be the effect of just removing it. I have seen this topic which is old-ish, but describes my problem and is about a similar computer. The solution in this topic was to compile a new kernel using a spanish guide, which seems a bit extreme to me, so I'm kinda hoping for a better solution than that.

• How to best migrate one Windows 2008 R2 / SharePoint / Exchange / Terminal Services (All-in-one) int

  - by MadBoy

  Hello, My client has one machine with Windows 2008 R2 and everything on it. By everything I mean AD, DNS, SharePoint 2010 Standard, Exchange 2010 Standard, Terminal Services, Office 2010 and a bunch of additional apps. Everything stands on I7 x 2 and 36gb ram for 7 people total. I've decided that we should virtualize it and split things into 4 VM's and keep host only with Hyper-V installed to host all the machines. What problems should I expect? What good advices can you give. My plan is that when i move everything to VM's i will move vm's to safe place and format the host as it has a lot of really bad things happening on it. But this also means that everything will be wiped from current solution so I have to be sure that Exchange etc will work when host gets wiped. MadBoy

• Dell Mini 9 Integrated Microphone -- not working

  - by Josh Eismanaf

  Im running the latest Debian version, 6.0 on my Dell Mini 9.Webcam and sound work, but microphone is a no-go. I hope even though it is Debian, fellow Linux users can help. In Alsamixer (1.0.23), I have Capture, Digital, and Mic settings all the way up. There are no options for adjusting "Front" mic settings. (May have been for older alsamixer versions?) In Sound Recorder, playback has loud noise/feedback? Under Preferences in Volume Control under the Recording tab, both Capture and Digital are permanently checked, regardless if I uncheck them. I'm not sure how to interpret the above, but I am just trying to offer as much relevant background information as I can. I've been scouring forums for the answer, but to no avail. Most questions/answers are from 2008, and couldn't find a solution. I'm not very handy with the Linux machine, but love to learn / am learning. Also, I've attempted the solution here, and it didn't work. Thanks, in advance, for your help!

• Why do I have no TTY on a basic Ubuntu 9.10 server install?

  - by pr1001

  I have reinstalled Ubuntu 9.10 Server several times on a bog standard 1RU server and each time I finish the install and reboot I see GRUB run and am then presented with a black screen. The machine is running just fine, as I am able to SSH in, but I can't see anything on the attached monitor. I have a simple LCD screen connected via VGA and a signal is apparently being output to it, as it doesn't go asleep. Looking at /var/log/syslog I see: Mar 24 14:57:44 bridge5 rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ] However, I later see: Mar 24 14:57:44 bridge5 kernel: [ 0.001368] console [tty0] enabled Any thoughts? Thanks!
