  • Interop.Outlook.UserProperties.Add causing problem during connection time

    - by aanataliya
    Hi All, I have created a plug-in for outlook. Plug-in has only below code. private void OnNewOutlookInspector(Outlook.Inspector OutlookInsptr) { Outlook.MailItem MlItem = (Outlook.MailItem)OutlookInsptr.CurrentItem; //if I remove below line. Everything is working fine. MlItem.UserProperties.Add("INSPINIT", Outlook.OlUserPropertyType.olText , true , true ).Value = "1"; } public void OnConnection(object application, Extensibility.ext_ConnectMode connectMode, object addInInst, ref System.Array custom) { applicationObject = application; addInInstance = addInInst; MessageBox.Show("in connection new 2"); OutlkApp = (Outlook.Application)application; OutlkInsptrs = OutlkApp.Inspectors; OutlkInsptrs.NewInspector += new Outlook.InspectorsEvents_NewInspectorEventHandler(OnNewOutlookInspector); } Problem I am facing is, When I send HTML mail while plug-in is enabled, receiving end it is being received as a plain text.

  • recommendations for efficient offsite remote backup solution of vm's

    - by senorsmile
    I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?

  • Aliased network interfaces and isc dhcp server

    - by Jonatan
    I have been banging my head on this for a long time now. There are many discussions on the net about this and similar problems, but none of the solutions seems to work for me. I have a Debian server with two ethernet network interfaces. One of them is connected to internet, while the other is connected to my LAN. The LAN network is 10.11.100.0 (netmask 255.255.255.0). We have some custom hardware that use network 10.4.1.0 (netmask 255.255.255.0) and we can't change that. But we need all hosts on 10.11.100.0 to be able to connect to devices on 10.4.1.0. So I added an alias for the LAN network interface so that the Debian server acts as a gateway between 10.11.100.0 and 10.4.1.0. But then the dhcp server stopped working. The log says: No subnet declaration for eth1:0 (no IPv4 addresses). ** Ignoring requests on eth1:0. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1:1 is attached. ** No subnet declaration for eth1:1 (no IPv4 addresses). ** Ignoring requests on eth1:1. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1:1 is attached. ** I had another server before, also running Debian but with the older dhcp3 server, and it worked without any problems. I've tried everything I can think of in dhcpd.conf etc, and I've also compared with the working configuration in the old server. The dhcp server need only handle devices on 10.11.100.0. Any hints? Here's all relevant config files: /etc/default/isc-dhcp-server INTERFACES="eth1" /etc/network/interfaces (I've left out eth0, that connects to the Internet, since there is no problem with that.) auto eth1:0 iface eth1:0 inet static address 10.11.100.202 netmask 255.255.255.0 auto eth1:1 iface eth1:1 inet static address 10.4.1.248 netmask 255.255.255.0 /etc/dhcp/dhcpd.conf ddns-update-style none; option domain-name "???.com"; option domain-name-servers ?.?.?.?; default-lease-time 86400; max-lease-time 604800; authorative; subnet 10.11.100.0 netmask 255.255.255.0 { option subnet-mask 255.255.255.0; pool { range 10.11.100.50 10.11.100.99; } option routers 10.11.100.102; } I have tried to add shared-network etc, but didn't manage to get that to work. I get the same error message no matter what...

  • Fix/Bypass "Cannot connect to the real website-blocked" error in Google Chrome with OpenDNS blocking

    - by George H
    I have a large problem with Chrome in my organisation. I use DNS to manage web site blocking, for sites which are not appropriate and are potentially a risk to the organisation where I do this. I only want to use Chrome over the network, as Internet Explorer has compatibility problems with some sites that we use (We cannot change this either or use different sites). Therefore using internet explorer is not a solution. I do not want to install a different browser, for multiple reasons. Mainly because of the difficulty of rewriting the customised add-ons that we use. However, recently, I have had lots of problems with Chrome SSL Errors. I cannot use my custom OpenDNS block pages, which uses the contact form to request an unblocking. Chrome often blocks OpenDNS for sites (a good example is Facebook) that request HTTPS. Some sites like https://internetbadguys.com (OpenDNS example) This means that chrome refuses to load the blocking page, explaining that the site is blocked. Instead they often call IT support, but they want a solution, as they are sick of getting lots of SSL errors. I have tried looking into ways to turning this off. I have tried: Typing "proceed". That didn't work. Typing "proceed", pressing enter. Didn't work I cannot find phishing and anti-malware any more in Chrome, from the internet guides. Not using HTTPS. However there is an automatic redirect to HTTPS on most sites. Therefore the error keeps coming up. Checking my clocks. They were correct. Does anyone have an idea on how to disabling, bypassing or working around this "feature"? EDIT: This is an example what I am talking about - I found that on google images. I do not block google. EDIT 2: My clocks are correct. I cannot stop using OpenDNS either. EDIT 3: My question is: How do I stop chrome from refusing to load pages that are blocked by OpenDNS, where the server has explicitly requested HTTPS.

  • HAProxy causing delay

    - by user1221444
    I am trying to configure HAProxy to do load balancing for a custom webserver I created. Right now I am noticing an increasing delay with HAProxy as the size of the return message increases. For example, I ran four different tests, here are the results: Response 15kb through HAProxy: Avg. response time: .34 secs Transacation rate: 763 trans/sec Throughput: 11.08 MB/sec Response 2kb through HAProxy: Avg. response time: .08 secs Transaction rate: 1171 trans / sec Throughput: 2.51 MB/sec Response 15kb directly to server: Avg. response time: .11 sec Transaction rate: 1046 trans/sec throughput: 15.20 MB/sec Response 2kb directly to server: Avg. Response time: .05 secs Transaction rate: 1158 trans/sec Throughput: 2.48 MB/sec All transactions are HTTP requests. As you can see, there seems to be a much bigger difference between response times for when the response is bigger, than when it is smaller. I understand there will be a slight delay when using HAProxy. Not sure if it matters, but the test itself was run using siege. And during the test there was only one server behind the HAProxy(the same that was used in the direct to server tests). Here is my haproxy.config file: global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 10000 user haproxy group haproxy daemon #debug defaults log global mode http option httplog option dontlognull retries 3 option redispatch option httpclose maxconn 10000 contimeout 10000 clitimeout 50000 srvtimeout 50000 balance roundrobin stats enable stats uri /stats listen lb1 10.1.10.26:80 maxconn 10000 server app1 10.1.10.200:8080 maxconn 5000 I couldn't find much in terms of options in this file that would help my problem. I have heard suggestions that I may have to adjust a few of my sysctl settings. I could not find a lot of information on this however, most documentation is for Linux 2.4 and 2.6 on the sysctl stuff, I am running 3.2(Ubuntu server 12.04), which seems to auto tuning, so I have no clue what I should or shouldn't be changing. Most settings changes I tried had no effect or a negative effect on performance. Just a notice, this is a very preliminary test, and my hope is that at deployment time, my HAProxy will be able to balance 10k-20k requests/sec to many servers, so if anyone could provide information to help me reach that goal, it would be much appreciated. Thank you very much for any information you can provide. And if you need anymore information from me please let me know, I will get you anything I can.

  • NX Client for Windows 7 Opens Remote Desktop in Multiple Windows

    - by Corey Kennedy
    What I'm trying to do: access my Ubuntu desktop remotely via NX Client on my Windows 7 laptop. My environment: server: Ubuntu 10.10 on AMD 1Ghz/512MB RAM PC client: Windows 7 on ThinkPad sl510 Software: server is running NXServer 3.4.0. Using xfce4 window manager. Laptop is using NXClient for Windows In my NX Client "Desktop" settings I've selected "Unix" and "Custom" for OS and environment. I've also specified "startxfce4" as the application to launch when NX connects. I am able to authenticate an NX session on my laptop. By this I mean, I can start the client on my laptop, enter credentials for my Linux user, and NX establishes a connection to the server and attempts to open a remote desktop window. The problem, though, is that this remote desktop is "fragmented" into many Windows. One window will display the bulk of my desktop (complete with desktop icons for "Home," "File System," and "Trash") while another window will contain the taskbar, and another window will contain the application strip. I can select each of these Windows individually, but I cannot click on any objects within them. I've searched Super User, Ubuntu Forums, NX help, Server Fault, and tried many Google searches - none have turned up another case of this particular problem. I'm stumped. Does anyone have any suggestions for what I might try? I'm guessing the problem has to do with my xfce config files, but I've only just setup this server - it's been a long time since I've used Linux and there's a lot I just don't know. What I am NOT trying to do: use Desktop sharing from Ubuntu, whereby I VNC into a desktop that I've already established on the server. I am trying to configure this Linux box as a headless server that I can stash someplace out-of-the-way in my house, then interact with through my laptop. I don't want to have a monitor or keyboard connected to the Linux box. Thanks for your help! edit: 1/19/2011 Well, this is truly bizarre. To my knowledge I've made no changes to either system - the laptop or the server. But today after starting up the server for the first time in a few days, and making sure that nxserver was running, I was able to connect with the nxclient from my laptop with no problems. I have a full desktop in a single window and I am able to interact with it normally. This is really weird, but the problem seems to be resolved.

  • Can't connect to shared folders anymore?

    - by HuskyHuskie
    My home server is running Windows Server 2008 R2. I've had it running for almost a year now without any issues with shared folders. This past week I had an issue with my modem which required it to be power cycled and with that I power cycled my router. After that I haven't been able to connect to my shared network folders. I have no idea why that would even cause an issue as I've power cycled my networking equipment in the past without issues and none of my settings appear to have been lost. I am mapping these drives on my Windows 7 Ultimate machine using "Map Network Drive", from there I enter \\SERVER\Storage as I'm trying to connect to my shared folder named Storage. I receive the following error every time I try mapping the drive: Windows cannot access \\Server\Storage Check the spelling of the name. Otherwise there might be a problem with your network. To try to identify and resolve network problems, click Diagnose. Details: Error code: 0x80070035 The network path was not found. When I click Diagnose I get the following: Problems found file and print sharing resource (SERVER) is online but isn't responding to connection attempts. The remote computer isn't responding to connection on port 445, possibly due to firewall or security policy settings, or because it might be temporarily unavailable. Windows couldn't find any problems with the firewall on your computer. I've tried this from multiple computers with the same issue too. To resolve the problems so far I've tried: Disabling the firewall on SERVER Reinstalling File Services Modifying NetBT\Parameters registry values Adding a custom inbound rule for port 445 Adding port forwarding on my router for port 445 Recreating the shared folders Checking and rechecking the shared folder permissions. Resetting my user account password on the server used to access the shared folder. I'm pulling my hair out with this problem mainly because it came out of nowhere. It was working fine the night before and the next day it just stopped working. Any ideas of what I could try next are much appreciated. It should also be noted that this server is used as a web server too and that functionality still works correctly.

  • IE8 Refuses to run Javascript from Local Hard Drive

    - by Josh Stodola
    I have a problem that just started at work recently and the network manager is certain he did not change anything with the group policy. Anyways, here is a detailed description of the problem. My machine is Windows XP SP3, and I use IE8 to browse. We have McAffee anti-virus software that I am unable to configure. I use the following file to test... <!DOCTYPE html> <html> <head> <title>Javascript Test</title> </head> <body> <script type="text/javascript"> document.write("<h1>PASS</h1>"); </script> <noscript> <h1>FAIL</h1> </noscript> </body> </html> When I open this file from the C: drive, it fails every time. If I execute it anywhere else (local/remote web server or on a mapped network drive), it works just fine. When I am simply browsing the Internet, Javascript on web sites works just fine. It is only failing on files running from my C: drive. Additionally, I have had a couple other programmers in the department try this file on their C: drive, and it works fine for them. So I don't believe it is a group policy thing. I need to fix this because I do extensive testing from my C: drive, and I am accustomed to doing so. I don't want to get into the habit of moving files to a different drive just to test. Things I have tried: Enabled "Allow Active Content to Run Files on My Computer" in Options | Advanced | Security Enabled "Allow Active Scripting" in Options | Security | Custom Level Verified that "Script" was not checked as disabled in Developer Toolbar Added localhost to Trusted Sites in Options Disabled McAffee completely (momentarily, with help from network admin) Used an older DOCTYPE in my test HTML page Re-installed IE8 completely Ran regsvr32 on the JScript.dll Slammed keyboard I am sure that there is a setting somewhere that will fix this problem, possibly in the registry. I would not be surprised if it was related to the developer toolbar. At this point I do not know where else to look. Can anyone help me resolve this problem? EDIT: Regardless of the bounty, this issue is still ongoing.

  • How to stop Apache from crashing my entire server?

    - by CyberShadow
    I maintain a Gentoo server with a few services, including Apache. It's fairly low-end (2GB of RAM and a low-end CPU with 2 cores). My problem is that, despite my best efforts, an over-loaded Apache crashes the entire server. In fact, at this point I'm close to being convinced that Linux is a horrible operating system that isn't worth anyone's time looking for stability under load. Things I tried: Adjusting oom_adj for the root Apache process (and thus all its children). That had close to no effect. When Apache was overloaded it would bring the system to a grind, as the system paged out everything else before it got to kill anything. Turning off swap. Didn't help, it would unload memory paged to binaries of processes and other files on /, thus causing the same effect. Putting it in a memory-limited cgroup (limited to 512 MB of RAM, 1/4th of the total). This "worked", at least in my own stress tests - except the server keeps crashing under load (basically stalling all other processes, inaccessible via SSH, etc.) Running it with idle I/O priority. This wasn't a very good idea in the end, because it just caused the system load to climb indefinitely (into the thousands) with almost no visible effect - until you tried to access an unbuffered part of the disk. This caused the task to freeze. (So much for good I/O scheduling, eh?) Limiting the number of concurrent connections to Apache. Setting the number too low caused web sites to become unresponsive due to most slots being occupied with long requests (file downloads). I tried various Apache MPMs without much success (prefork, event, itk). Switching from prefork/event+php-cgi+suphp to itk+mod_php. This improved performance, but didn't solve the actual problem. Switching I/O schedulers (cfq to deadline). Just to stress this out: I don't care if Apache itself goes down under load, I just want the rest of my system to remain stable. Of course, having Apache recover quickly after a brief period of intensive load would be great to have, but one step at a time. Right now I am mostly dumbfounded by how can humanity, in this day and age, design an operating system where such a seemingly simple task (don't allow one system component to crash the entire system) seems practically impossible - or at least, very hard to do. Please don't suggest things like VMs or "BUY MORE RAM". Some more information gathered with a friend's help: The processes hang when the cgroup oom killer is invoked. Here's the call trace: [<ffffffff8104b94b>] ? prepare_to_wait+0x70/0x7b [<ffffffff810a9c73>] mem_cgroup_handle_oom+0xdf/0x180 [<ffffffff810a9559>] ? memcg_oom_wake_function+0x0/0x6d [<ffffffff810aa041>] __mem_cgroup_try_charge+0x32d/0x478 [<ffffffff810aac67>] mem_cgroup_charge_common+0x48/0x73 [<ffffffff81081c98>] ? __lru_cache_add+0x60/0x62 [<ffffffff810aadc3>] mem_cgroup_newpage_charge+0x3b/0x4a [<ffffffff8108ec38>] handle_mm_fault+0x305/0x8cf [<ffffffff813c6276>] ? schedule+0x6ae/0x6fb [<ffffffff8101f568>] do_page_fault+0x214/0x22b [<ffffffff813c7e1f>] page_fault+0x1f/0x30 At this point, the apache memory cgroup is practically deadlocked, and burning CPU in syscalls (all with the above call trace). This seems like a problem in the cgroup implementation...

  • OSError : [Errno 38] Function not implemented - Django Celery implementation

  • Network use of Gaming PC

    - by Matthew Patrick Cashatt
    Background After YEARS of waiting, I built the custom gaming PC of my dreams: Intel i7 - 975 Extreme Edition 3.3ghz (overclocked to 4.0) ATI Radeon 5970 2gb Corsair 256 gb SSD Drive 2 TB Sata II 3.0 7200rpm data drive 12 GB Kingston Hyper-X (1600mhz) DDR3 Windows 7 Ultra 64 bit And so on. . . Problem I hooked this beast up to our home theater and settled in for a great gaming season only to realize a couple of drawbacks: It's hard to accurately wax bad guys using a keyboard in your lap whilst reclined on your couch (and using a wireless keyboard). It's hard to read the text on the screen (i.e. menus, etc). I find that a 1:1 ratio (screen diagonal inch to inch away from screen) is optimum, but using the home theater, it's more like 1:3 which has me squinting unless I sit on the coffee table. The wife always seems to want the TV the same time I do and, unfortunately "Real Housewives of Beverly Hills" and Battlefield BC don't mix. I am losing the battle in the home theater room, but the PC has to stay there (long story). So, this leaves me with the option of playing in my home office which is about 30 feet away from the home theater. I am a software developer so I have a pretty decent set up in my office--multiple 1080p monitors, HP Envy 17 which can run games like Crysis in 720p with out stammering too much. Also, I can game very comfortably at my desk in the office. Still, even though the set up in my office can run games well enough, I don't want to regress to that when I have worked YEARS for an awesome gaming PC that can run everything on ultra high settings. My Question What are my options for running my games on the beastly desktop in the Home Theater, but physically playing in my office about 30 feet away? A really long HDMI cable? LAN/RDC? Details that May Help We have an open crawlspace so running cable from HT room to office is no problem. I already have networked the house with a LAN Any help is GREATLY appreciated. Thanks, Matt

  • Getting Classic ASP to work in .js files under IIS 7

    - by Abdullah Ahmed
    I am moving a clients classic asp webapp to a new IIS7 based server. The site contains some .js files which have javascript but also classic asp in <% % tags which contains a bunch of conditional statements designed to spit out pieces of javascript based on session state variables. Here's a brief example of what the file could be like.... var arrHOFFSET = -1; var arrLeft ="<"; var arrRight = ">"; <% If ((Session("dashInv") = "True") And ((Session("systemLevelStaff") = "4") Or (Session("systemLevelCompany") = "4"))) Then %> addMainItem("/MgmtTools/WelcomeInventory.asp?wherefrom=salesMan","",81,"center","","",0,0,"","","","",""); <% Else %> <% If (Session("dashInv") = "False") And ((Session("systemLevelStaff") = "4") Or (Session("systemLevelCompany") = "4")) Then %> <% Else %> addMainItem("/calendar/welcome.asp","",81,"center","","",0,0,"","","","",""); <% End If %> <% End If %> defineSubmenuProperties(135,"center","center",-3,0,"","","","","","",""); Currently this file (named custom.js for example) will start throwing js errors, because the server doesnt seem to recognize the asp code in it and therefore does not parse it. I know I need to somehow specify that a .js file should also be treated like an .asp file and run through parsing it. However I am not sure how to go about doing this. Here is what I've tried so far... Under the Server node in IIS under HANDLER MAPPINGS I created a new Script Map with the following settings. Request Path: *.js Executable: C:\Windows\System32\inetsrv\asp.dll Name: ASPClassicInJSFiles Mapping: Invoke Handler only if request is mapped to : File Verbs: All verbs Access: Script I also created a similar handler under the site node itself. Under MIME Types .js is defined as application/x-javascript None of these work. If I simply rename the file to have .asp extension then things work, however this app is poorly coded and has literally 100's of files with the .js files included in them under various names and locations, so rename, search and replace is the last option I have.

  • Intermittent lockups, unable to diagnose in over a year

    - by Magsol
    Here's a real doosie; I may just give my firstborn child to whomever helps me solve this problem. In July 2008, I assembled what would be my desktop computer for graduate school. Here are the specs of the machine I built: Thermaltake 750W PSU Corsair Dominator 2x2GB 240-pin SDRAM Thermaltake Tower Asus P5K Deluxe Motherboard Intel Core 2 Quad Q9300 2.5GHz CPU 2 x GeForce 8600 GT WD Caviar Blue 640GB hard drive CD burner DVD burner Soon thereafter, I ordered a new motherboard (because I was an idiot; that first motherboard supported CrossFire, not SLI), an Asus P5N-D. I was originally running Windows XP SP3. Pretty much right into the start of the fall semester, my desktop would simply lock up after awhile. If my system was largely idling, it would be after 1-3 days. If was gaming, it often happened an hour or two into my gaming session, indicating a link to activity level. Here's where it started getting interesting. I started looking at the system temps. The CPU was warmer than it should have been (~60s C), so I purchased some more efficient cooling compound a way better cooler for it. Now it hardly goes over 40 C. Intel was even kind enough to swap it out for free, just to rule it out. Lockups continued. The graphics cards were also running pretty warm: about 60 C idling. Removing one of them seemed to improve stability a little bit...as in, it wouldn't lock up quite as frequently, but still always eventually locked up. But it didn't matter which card I used or removed, the lockups continued. I reverted back to the original motherboard, the P5K Deluxe. Lockups continued. I purchased an entirely new motherboard, eVGA's nForce 750i. Lockups continued. Ran memtest86+ over and over and over, with no errors. Even RMA'd the memory. Lockups continued. Replaced the PSU with a Corsair 750W PSU. Lockups continued. Tried disconnecting all IDE drives (HDDs are SATA). Lockups continued. Replaced both graphics cards with a single Radeon HD 4980. Average temps are now always around 50 C when idling, 60 C only when gaming. Lockups continued. Throughout the whole ordeal, the system has been upgraded from Windows XP SP3 to Vista 32-bit, to Vista 64-bit, and is now at Windows 7 64-bit. Lockups have occurred at every step along the way (each OS was in place for at least a few months before the next upgrade). Edit: By "upgrade" I mean clean install each time. In addition to those reformats, I have performed many, many other reformats of the system and a reinstall of whatever OS had been previously installed in an attempt to rectify this problem, to no avail./Edit When the system locks up, there's no blue screen, no reboot, no error message of any kind. It simply freezes in place until I hit the reset button. Very, very rarely, once Windows boots back up, the system informs me that Windows has recovered from an error, but it can never find the source aside from some piece of hardware. I've swapped out every component in this computer, and there are more fans in it than I care to count...though for the sake of completeness: top 80mm case fan (out) rear 80mm case fan (out) rear 120mm case fan (out) front 120mm case fan (in) side 250mm case fan (in) giant CPU fan on-board motherboard fan (the eVGA board) triple-fan memory setup (came with the memory) PSU internal fan another 120mm fan I stuck on the underside of the video card to keep hot air from collecting at the bottom of the case I'm truly out of ideas. ANY help at all would be oh-so-very GREATLY appreciated. Thank you!

  • Netcat file transfer problem

    - by thepurplepixel
    I have two custom scripts I just wrote to facilitate transferring files between my VPS and my home server. They are both written in bash (short & sweet): To send: #!/bin/bash SENDFILE=$1 PORT=$2 HOST='<my house>' HOSTIP=`host $HOST | grep "has address" | cut --delimiter=" " -f 4` echo Transferring file \"$SENDFILE\" to $HOST \($HOSTIP\). tar -c "$SENDFILE" | pv -c -N tar -i 0.5 | lzma -z -c -6 | pv -c -N lzma -i 0.5 | nc -q 1 $HOSTIP $PORT echo Done. To receive: #!/bin/bash SERVER='<myserver>' SERVERIP=`host $SERVER | grep "has address" | cut --delimiter=" " -f 4` PORT=$1 echo Receiving file from $SERVER \($SERVERIP\) on port $PORT. nc -l $PORT | pv -c -N netcat -i 0.5 | lzma -d -c | pv -c -N lzma -i 0.5 | tar -xf - echo Done. The problem is that, for a very quick second, I see something flash along the lines of "Connection Refused" (before pv overwrites it), and no file is ever transferred. The port is forwarded through my router, and nmap confirms it: ~$ sudo nmap -sU -PN -p55515 -v <my house> Starting Nmap 5.00 ( http://nmap.org ) at 2010-04-21 18:10 EDT NSE: Loaded 0 scripts for scanning.

The receiver has no firewall, and outbound traffic on that port is allowed on the sender. I have no idea what to troubleshoot next. Any ideas? P.S.: Feel free to move this to SO/SF if you feel it would fit better there.

  • Windows DHCP Server - get notification when a non-AD joined device gets an IP address

    - by TheCleaner
    SCENARIO To simplify this down to it's easiest example: I have a Windows 2008 R2 standard DC with the DHCP server role. It hands out IPs via various IPv4 scopes, no problem there. WHAT I'D LIKE I would like a way to create a notification/eventlog entry/similar whenever a device gets a DHCP address lease and that device IS NOT a domain joined computer in Active Directory. It doesn't matter to me whether it is custom Powershell, etc. Bottom line = I'd like a way to know when non-domain devices are on the network without using 802.1X at the moment. I know this won't account for static IP devices. I do have monitoring software that will scan the network and find devices, but it isn't quite this granular in detail. RESEARCH DONE/OPTIONS CONSIDERED I don't see any such possibilities with the built in logging. Yes, I'm aware of 802.1X and have the ability to implement it long-term at this location but we are some time away from a project like that, and while that would solve network authentication issues, this is still helpful to me outside of 802.1X goals. I've looked around for some script bits, etc. that might prove useful but the things I'm finding lead me to believe that my google-fu is failing me at the moment. I believe the below logic is sound (assuming there isn't some existing solution): Device receives DHCP address Event log entry is recorded (event ID 10 in the DHCP audit log should work (since a new lease is what I'd be most interested in, not renewals): http://technet.microsoft.com/en-us/library/dd759178.aspx) At this point a script of some kind would probably have to take over for the remaining "STEPS" below. Somehow query this DHCP log for these event ID 10's (I would love push, but I'm guessing pull is the only recourse here) Parse the query for the name of the device being assigned the new lease Query AD for the device's name IF not found in AD, send a notification email If anyone has any ideas on how to properly do this, I'd really appreciate it. I'm not looking for a "gimme the codez" but would love to know if there are alternatives to the above list or if I'm not thinking clear and another method exists for gathering this information. If you have code snippets/PS commands you'd like to share to help accomplish this, all the better.

  • dd-wrt router firmware QoS troubleshooting

    - by Jeff Atwood
    I've been using the dd-wrt firmware on my router and I like it a lot! But -- I'm not sure the quality of service (QoS) is working on it. I have it set up as follows: http, port 80 -- Premium bittorrent, port 6969 -- Bulk https, port 443 -- Premium dns, port 53 -- Premium Per the QoS documentation, these levels are: bandwidth is allocated based on the following percentages of uplink and downlink values for each class: Exempt: 100mbps - ignores global limits. Premium: 75% - 100% Express: 15% - 100% Standard: 10% - 100% Bulk: 1.5% - 100% This doesn't entirely seem to work, though -- with busy torrents going I get major pauses in my web browsing which sucks! The QoS documentation gives some steps to check the QoS ... What you'll be interested to look at will be the first set of source and destination IP, including the port numbers. Next the presence of l7proto and the "mark" field. The entries indicate the current live connection QoS priority applied on them based on the "mark" field. The "mark" values correspond to the following Exempt: 100 Premium: 10 Express: 20 Standard: 30 Bulk: 40 (no QoS matched): 0 You may see "mark=0" for some l7proto service even though they are in configured in the list of QoS rules. This may mean that the layer 7 pattern matching system didn't match a new or changed header for that protocol. Custom service on port matches will usually take care of these. On port 6969 (bittorrent) I see a weird mixture of stuff with mark=0 and mark=40 like so cat /proc/net/ip_conntrack udp 17 105 src=98.162.182.42 dst=1.2.3.4 sport=64512 dport=6969 packets=3 bytes=290 src=10.0.0.2 dst=98.162.182.42 sport=6969 dport=64512 packets=4 bytes=202 [ASSURED] mark=0 secmark=0 use=1 tcp 6 117 TIME_WAIT src=98.248.173.174 dst=1.2.3.4 sport=51114 dport=6969 packets=12 bytes=704 src=10.0.0.2 dst=98.248.173.174 sport=6969 dport=51114 packets=10 bytes=440 [ASSURED] mark=40 secmark=0 use=1 tcp 6 598 ESTABLISHED src=165.132.128.201 dst=1.2.3.4 sport=57218 dport=6969 packets=8024 bytes=9919881 src=10.0.0.2 dst=165.132.128.201 sport=6969 dport=57218 packets=4211 bytes=239607 [ASSURED] mark=0 secmark=0 use=1 tcp 6 586 ESTABLISHED src=68.46.9.24 dst=1.2.3.4 sport=64688 dport=6969 packets=6 bytes=490 src=10.0.0.2 dst=68.46.9.24 sport=6969 dport=64688 packets=8 bytes=944 [ASSURED] mark=40 secmark=0 use=1 udp 17 45 src=222.254.228.38 dst=1.2.3.4 sport=25438 dport=6969 packets=5 bytes=454 src=10.0.0.2 dst=222.254.228.38 sport=6969 dport=25438 packets=3 bytes=154 [ASSURED] mark=0 secmark=0 use=1 ( full file visible at http://pastebin.com/AZE6EtWm ) I've been playing around with this log for a little while and I can't see any patterns! Why is some port 6969 bittorrent traffic tagged mark=0 (not matched) by dd-wrt's QoS while others are tagged mark=40 (Bulk) .. any ideas?

  • Anyone else experiencing high rates of Linux server crashes during a leap second day?

    - by Bron Gondwana
    POSTMORTEM Anticlimax: only thing that died was my VPN (openvpn) link to the cluster, so there was an exciting few seconds while it re-established. Everything else was fine. Starting back ntp everywhere. If you look at Marco's blog at http://my.opera.com/marcomarongiu/blog/2012/06/01/an-humble-attempt-to-work-around-the-leap-second - he has a solution for phasing the time change over 24 hours using ntpd -x to avoid the 1 second skip. Give that a go if it matters to you. For the systems I run, the jump isn't a problem. Just today, Sat June 30th - starting soon after the start of the day GMT. We've had a handful of blades in different datacentres as managed by different teams all go dark - not responding to pings, screen blank. They're all running Debian Squeeze - with everything from stock kernel to custom 3.2.21 builds. Most are Dell M610 blades, but I've also just lost a Dell R510 and other departments have lost machines from other vendors too. There was also an older IBM x3550 which crashed and which I thought might be unrelated, but now I'm wondering. The one crash which I did get a screen dump from said: [3161000.864001] BUG: spinlock lockup on CPU#1, ntpd/3358 [3161000.864001] lock: ffff88083fc0d740, .magic: dead4ead, .owner: imapd/24737, .owner_cpu: 0 Unfortunately the blades all supposedly had kdump configured, but they died so hard that kdump didn't trigger - and they had console blanking turned on. I've disabled console blanking now, so fingers crossed I'll have more information after the next crash. Just want to know if it's a common thread or "just us". It's really odd that they're different units in different datacentres bought at different times and run by different admins (I run the FastMail.FM ones)... and now even different vendor hardware. Most of the machines which crashed had been up for weeks/months and were running 3.1 or 3.2 series kernels. The most recent crash was a machine which had only been up about 6 hours running 3.2.21. THE WORKAROUND Ok people, here's how I worked around it. disabled ntp: /etc/init.d/ntp stop created http://linux.brong.fastmail.fm/2012-06-30/fixtime.pl (code stolen from Marco, see blog posts in comments) ran fixtime.pl without an argument to see that there was a leap second set ran fixtime.pl with an argument to remove the leap second NOTE: depends on adjtimex. I've put a copy of the squeeze adjtimex binary at http://linux.brong.fastmail.fm/2012-06-30/adjtimex - it will run without dependencies on a squeeze 64 bit system. If you put it in the same directory as fixtime.pl, it will be used if the system one isn't present. Obviously if you don't have squeeze 64 bit... find your own. I'm going to start ntp again tomorrow. As an anonymous user suggested - an alternative to running adjtimex is to just set the time yourself, which will presumably also clear the leapsecond counter.

  • CPU/JVM/JBoss 7 slows down over time

    - by lukas
    I'm experiencing performance slow down on JBoss 7.1.1 Final. I wrote simple program that demostrates this behavior. I generate an array of 100,000 of random integers and run bubble sort on it. @Model public class PerformanceTest { public void proceed() { long now = System.currentTimeMillis(); int[] arr = new int[100000]; for(int i = 0; i < arr.length; i++) { arr[i] = (int) (Math.random() * 200000); } long now2 = System.currentTimeMillis(); System.out.println((now2 - now) + "ms took to generate array"); now = System.currentTimeMillis(); bubbleSort(arr); now2 = System.currentTimeMillis(); System.out.println((now2 - now) + "ms took to bubblesort array"); } public void bubbleSort(int[] arr) { boolean swapped = true; int j = 0; int tmp; while (swapped) { swapped = false; j++; for (int i = 0; i < arr.length - j; i++) { if (arr[i] > arr[i + 1]) { tmp = arr[i]; arr[i] = arr[i + 1]; arr[i + 1] = tmp; swapped = true; } } } } } Just after I start the server, it takes approximately 22 seconds to run this code. After few days of JBoss 7.1.1. running, it takes 330 sec to run this code. In both cases, I launch the code when the CPU utilization is very low (say, 1%). Any ideas why? I run the server with following arguments: -Xms1280m -Xmx2048m -XX:MaxPermSize=2048m -Djava.net.preferIPv4Stack=true -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djboss.modules.system.pkgs=org.jboss.byteman -Djava.awt.headless=true -Duser.timezone=UTC -Djboss.server.default.config=standalone-full.xml -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n I'm running it on Linux 2.6.32-279.11.1.el6.x86_64 with java version "1.7.0_07". It's within J2EE applicaiton. I use CDI so I have a button on JSF page that will call method "proceed" on @RequestScoped component PerformanceTest. I deploy this as separate war file and even if I undeploy other applications, it doesn't change the performance. It's a virtual machine that is sharing CPUs with another machine but that one doesn't consume anything. Here's yet another observation: when the server is after fresh start and I run the bubble sort, It utilizes 100% of one processor core. It never switches to another core or drops utilization below 95%. However after some time the server is running and I'm experiencing the performance problems, the method above is utilizing CPU core usually 100%, however I just found out from htop that this task is being switched very often to other cores. That is, at the beginning it's running on core #1, after say 2 seconds it's running on #5 then after say 2 seconds #8 etc. Furthermore, the utilization is not kept at 100% at the core but sometimes drops to 80% or even lower. For the server after fresh start, even though If I simulate a load, it never switches the task to another core.

  • Why many applications close after opening a document or doing a specific actions?

    - by Mohsen Farjami
    I have some encrypted pdf files that have no problem and in my last windows, I could open them easily with Adobe Reader 9.2 and other pdf readers. But now, I can only open non-encrypted pdf files and one encrypted file with Adobe Reader. every time I open almost any encrypted pdf, it closes itself. Also, when I try to search a folder for a keyword with Foxit Reader, once it closed. This is not related to Adobe Reader, because I have the same problem with Word 2007. When I open a document, sometimes it closes instantly and sometimes it closes after a few seconds and sometimes it is stable. My windows is Fresh. I have installed it a few days ago.

  • Windows 2008 IIS 7.0 HTTP to HTTPS Redirect -- Versus IIS 6.0 Mechanism

    - by Dan7el
    This topic, creating a mechanism for redirection from HTTP to HTTPS on a Windows 2008 server running IIS 7.0 is a much written-about topic on the Internet. How this is done is really not so much my issue. My issue is more of explaining why this can't be done with the standard HTTP Redirect module that ships with Windows 2008 IIS 7.0. Instead, there are other methods needed that are more arduous. First, the IIS 6.0 method requires no externally available modules nor does it require any additional modifications to the web.config or any type of other development effort. It's outlined here: http://blogs.microsoft.co.il/blogs/dorr/archive/2009/01/13/how-to-force-redirection-from-http-to-https-on-iis-6-0.aspx And, you can see the basic steps are to run the snap-in, get the properties on the site, and do some modifications. Presto, you have the HTTP -- HTTP redirect setup. Now, on the IIS 7.0 platform, it doesn't seem this simple. An initial search found the following site: http://www.sslshopper.com/iis7-redirect-http-to-https.html Which has two separate approcates: 1. Involves installing a separately available Microsoft module -- URL Rewrite Module, and then adding XML to the web.config. 2. Custom Error Page. ...there might be other methods, but these are the basic ones and the first is listed as the primary method. But wait...There exists on the IIS 7.0 an HTTP Redirect Module. So...why can't I use the HTTP Redirect Module to do this very thing? This is really my big question. I need to know this because my management is going to insist I use the HTTP Redirect Module and set up the HTTP to HTTPS redirect in a similar fashion to how we do in IIS 6.0. Can someone please explain to me, in clean, simple, easy to understand, terms that both I and my management can understand as to why I need to go get the URL Rewrite Module and install that on the server and make the web.config changes suggested by the article instead of simply using the HTTP Redirect module that's already installed on the site? Thanks a bunch.

  • Dangers of Running Computers w/o Air Conditioning

    - by Daniel Bingham
    I recently moved in to an apartment with out air conditioning. This is fine most of the time as I am in upstate New York. It only ever gets above the high 70s during the hottest of the summer months. And when it does, I'm stubborn enough that I'll just deal with wearing minimal clothing around the house. However, I'm worried about my computers. I'm a software developer and gamer, so many of my machines are very high powered. And at least one of them is a server that must be left on 24/7 (not just a game server - also serves multiple websites). I've never before had to worry about the heat too much, as I always lived in buildings with central air. The in building temperature rarely got much above 70 F. All of the machines I built had good enough air cooling that I never saw a problem. Now the temperature in building is pushing 100F and I'm worried that the machines will not be able to keep themselves cool enough by simply blowing already hot air over themselves. The hottest of them I've turned off. However, the server I cannot. It's an old Dell (not custom build) that runs on a Pentium 4 (2.2GHz). It only has a single hard drive, integrated video. And it'd not running any processor intensive servers. Just basic LAMP. It used to run a MUD server, but that's off for now. So it should be idling most of the time. I haven't been able to find any sort of built in temperature sensors in the hardware... at least not any that the programs I've found in the Debian repository can read. And it's an inherited machine to which I do not have the full specs, so I don't know the tolerances anyway. How worried should I be about it melting down on me? How worried should I be about the hard drive melting or becoming corrupted? To generalize the question for other people, what are the safe temperature tolerances for most machines. How widely does it vary, and how does one go about determining when their machine is running too hot and needs to be shut down?

  • VirtualBox - multiple guests, each with a single bridged adapter?

    - by Martin
    I am running a dedicated server (located at Hetzner, Germany) that runs VirtualBox in order to virtualize several services accross multiple virtual guests. Those guests are supposed to communicate with each other (for instance, a virtual web server has to access a virtual database server); to be reachable from the dedicated server (for instance, SSH access); and to access the Internet via the dedicated server (for instance, to download security updates) Currently, this is achieved by having host-only adapter vboxnet0 on the dedicated server and two virtual interfaces on each guest. There, virtual adapter eth0 is attached to vboxnet0 (to achieve (1) and (2)), virtual adapter eth1 is attached to VirtualBox' NAT (to achieve (3)). Via eth0, the guests have access to a DHCP and a DNS server, both running on the dedicated server (there, bound to vboxnet0). This allows me to assign custom IP addresses and names. Via eth1, VirtualBox pushes a proper route that enables each guest to access the Internet (via eth0 on the dedicated server). This setup with two virtual adapters frequently leads to problems and at leasts complicates many things. For instance, on the dedicated server there is OpenVPN which allows to access the virtual machines via the Internet; futhermore, there is Shorwall that controls the incoming and outgoing network traffic between the Internet, the dedicated server, and the individual virtual machines. Not to mention automatic installation of servers via PXE... Therefore, I would prefer to have only one single virtual adapter on each guest which would be used for both incoming and outgoing connections. As far as I understand, one would basically use a bridged interface for that very purpose. Now the question arises: Which interface on the dedicated server would the bridge use? eth0 on the host server is not an option, as this is prohibited by the provider. A virtual interface eth0:0 would not make any sense, as a bridge always uses a physical interface (eth0 in this case). Would it be possible to create a bridged interface in each virtual machine that would "dangle in the air"? Thus, without a complement on the dedicated server? How would I have to set up the routing on the host server? Please note that the host / dedicated server has only one network adapter (eth0) which is connected to the provider's network.

  • Windows Service Limit Crashes Services on Startup

    - by Paul Williams
    We have developed a custom Windows service in C# as part of a large Enterprise application. Our QA department tests multiple versions of this service. The QA lab has several (over 20) copies of this service installed on one Windows 2003 test box. Each copy is in its own folder and has a unique service name, though each executable file is named the same (OurWindowsService.exe, for example). Each service uses the same Windows credentials (a domain user). The purpose of this service is to handle MSMQ messages. The queued messages do all sorts of important stuff. For some reason, they can run only 5 of these services at a time. When we start a 6th, the service crashes on startup. For example, I can start #1, #2, #3, #4, and #5. When I start #6, it crashes. However, if I stop #1 and start #6, #6 runs fine, and now #1 fails to start. When the services crash, the following error appears in the Windows event log: Faulting application OurWindowsService.exe, version 5.40.1.1, faulting module kernel32.dll, version 5.2.3790.4480, fault address 0x0000bef7. I was able to use WinDbg to generate a postmortem dump file. The dump file revealed that the crash occurs trying to delay load SHLWAPI.dll: 0:000> kb100 ChildEBP RetAddr Args to Child 0012ece4 79037966 c06d007e 00000000 00000001 KERNEL32!RaiseException+0x53 0012ed4c 790099ba 00000008 0012ed08 7c82860c mscoree!__delayLoadHelper2+0x139 0012ed98 790075b1 001550c8 0012edac 0012fb34 mscoree!_tailMerge_**SHLWAPI_dll**+0xd 0012edb0 79007623 001550c8 0012edf8 0012edf4 mscoree!XMLGetVersionWithSupported+0x22 0012ee00 790069a4 aa06f1b0 00000000 000001fe mscoree!RuntimeRequest::GetRuntimeVersion+0x56 0012f478 790077aa 00000001 7903fb4c 0012fb34 mscoree!RuntimeRequest::ComputeVersionString+0x5bd 0012f89c 79007802 00000001 0012f8b4 7903fb4c mscoree!RuntimeRequest::FindVersionedRuntime+0x11c 0012f8b8 79007b19 00000001 00000000 aa06fa6c mscoree!RuntimeRequest::RequestRuntimeDll+0x2c 0012ffa4 79007c02 00000001 0012ffbc 00000000 mscoree!GetInstallation+0x72 0012ffc0 77e6f23b 00000000 00000000 7ffdf000 mscoree!_CorExeMain+0x12 0012fff0 00000000 79007bf0 00000000 78746341 KERNEL32!BaseProcessStart+0x23 I believe the error code handed to Kernel32.RaiseException, c06d007e, means Module Not Found, but I'm not certain. Does this sound familiar to anyone? Are we hitting some limit on the number of service instances on some file name? Does MSMQ dislike more than 5 listening services?

  • Postfix to deliver mail to a virtual address mailbox

    - by Chloe
    Postfix version 2.6.6, Dovecot Version 2.0.9 I want to setup Postfix + Dovecot. Dovecot seems to be working. I can authenticate. However, the mailbox is empty! Nothing will get delivered! I followed many tutorials on Postfix + Dovecot but they seem to want to complicate things by using Dovecot LDA or MySQL. I just want it to be very simple and having Postfix deliver to the virtual mail boxes are fine. I don't need MySQL either. I already set up a custom password file that Dovecot uses for authentication and I can login to POP3 with SSL. I can see from the logs that Postfix is delivering to the system user accounts (the catch-all), instead of the virtual users that I set up in Dovecot. The SMTP + SSL authentication seems to work also. I can also see from the logs that Dovecot is checking the correct virtual mail folder. I just need to figure out how to get Postfix to deliver to the virtual mail boxes. I have the following which I believe are relevant. Let me know what other settings you need to see: alias_maps = hash:/etc/aliases mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = xxx.com myhostname = mail.xxx.com mynetworks = 99.99.99.99, 99.99.99.99 myorigin = $mydomain relay_domains = $mydestination, xxx.com, domain2.net, domain3.com sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = reject_non_fqdn_sender reject_non_fqdn_recipient reject_unknown_recipient_domain permit_sasl_authenticated check_relay_domains smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_sender_restrictions = check_sender_mx_access cidr:/etc/postfix/bogus_mx reject_invalid_hostname reject_unknown_sender_domain reject_non_fqdn_sender virtual_mailbox_base = /var/spool/vmail virtual_mailbox_domains = xxx.com, domain2.net, domain3.com virtual_minimum_uid = 444 Postfix master.cf: submission inet n - - - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_sasl_security_options=noanonymous -o smtpd_sasl_local_domain=$myhostname -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_sender_login_maps=hash:/etc/postfix/virtual -o smtpd_sender_restrictions=reject_sender_login_mismatch -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject Dovecot related: mail_location = maildir:~/Maildir passdb { args = /etc/dovecot/users.conf driver = passwd-file } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 user = postfix } } The virtual mail user: vmail:x:444:99:virtual mail users:/var/spool/vmail:/sbin/nologin Here is the /var/log/maillog when I try to send something to myself: Oct 25 22:10:05 308321 postfix/smtpd[2200]: connect from user-999.cable.mindspring.com[99.99.99.99] Oct 25 22:10:05 308321 postfix/smtpd[2200]: D224BD4753: client=user-999.cable.mindspring.com[99.99.99.99], sasl_method=LOGIN, [email protected] Oct 25 22:10:06 308321 postfix/cleanup[2207]: D224BD4753: message-id=<7DC3C163CFFC483AB6226F8D3D9969D2@dumbopc> Oct 25 22:10:06 308321 postfix/qmgr[2168]: D224BD4753: from=<[email protected]>, size=1385, nrcpt=1 (queue active) Oct 25 22:10:06 308321 postfix/smtpd[2200]: disconnect from user-999.cable.mindspring.com[99.99.99.99] Oct 25 22:10:06 308321 postfix/local[2208]: D224BD4753: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=1.1, delays=0.53/0.02/0/0.51, dsn=2.0.0, status=sent (delivered to mailbox) Oct 25 22:10:06 308321 postfix/qmgr[2168]: D224BD4753: removed

  • Supermicro IPMI on MBD-X8DAH+-F-O motherboard. Keyboard and mouse do not work after booting Windows Server 2008 R2

    - by LDelgado
    Hell Everyone, I built a server with the mentioned motherboard. I installed Windows Server 2008 R2 Enterprise on this server. IPMI is integrated on the motherboard with its own dedicated NIC. I've got that NIC configured with its own IP address. I can remote into it using IPMI, and I can remotely control the server settings before booting the OS ( BIOS, RAID configuration, etc). When the OS boots, I lose the mouse and keyboard. I cannot use the keyboard or mouse when installing the OS either. So the Keyboard and Mouse only work when no OS is loaded. Once the OS loads I lose it - that is my problem. I've been doing some research and trying a few things, but I have not been successful in fixing this issue. I may be wrong, but based on the things I've found online, it seems that the problem could be caused by the way the OS handles USB. The server is headless. There is no keyboard, mouse, or monitor plugged into it. When I boot up the OS and remote into it, I cannot see a mouse or keyboard listed in the Device Manager. Based on what I've read, it seems that the OS should detect a mouse and a keyboard when connecting remotely via IPMI. The following are the solutions I've tried. Nothing has worked so far: I've updated the firmware of the IPMI component to the latest firmware - 1.33. I made sure that the mouse mode was set to Absolute (Windows OS). I've loaded the factory defaults several times. I've enabled Port64h/60h Emulation under the USB settings in the BIOS. I've disabled USB legacy support in the BIOS. I made sure the firewall wasn't blocking IPMI (disabled the firewall). And that's about it. I've found threads in some forums from people having the same issue as me, but they were not running the same OS. They were either running Linux or FreeBSD. Most of them fixed their problem by selecting the right mouse mode (Linux in their case). There was one other that solved the problem by disabling USB Mass Storage mode. He stated "When I set it to disable USB Mass Storage when no image is loaded, the ukbd came alive, and I'm typing this on the IPMI Console. " source: http://freebsd.1045724.n5.nabble.com/IPMI-Console-No-luck-once-OS-is-booted-td3967868.html I suspect the solution described in the previous paragraph is somehow related to my problem. I've found several threads on the internet with issues describing the same problem, but none of them were with Windows Server 2008 R2. Again, I may be wrong, but it seems like that could be the issue. I just don't know how I go about applying a solution in Windows Server 2008 R2. In any case, I could use your expertise. Maybe I am missing something, or maybe I'm on the right track. Your help is much appreciated. Thank you in advance,
