  • Slow login to load-balanced Terminal Server 2008 behind Gateway Server

    - by Frans
    I have a small load-balanced (using Session Broker) Terminal Server 2008 farm behind a Gateway Server which is accessed from the Internet. The problem I have is that there is a delay of 20-30 seconds if the session broker switches the user to another server during login. I think this is related to the fact that I am forcing the security layer to be RDP rather than SSL. The background The Gateway server has a public routeable IP addres and DNS name so it can be accessed from the Internet and all users come in via this route (the system is used to provide access to hosted applications to external customers). The actual terminal servers only have internal IP addresses. This works really well, except that with a Vista or Windows 7 client, the Remote Desktop client will negotiate with the server to use SSL for the security layer. This then exposes the auto-generated certificate that TS1 or TS2 has - but since they are internal, auto-generated certificates, the client will get a stern warning that the certificate is not valid. I can't give the servers a properly authorised certificate as the servers do not have public routeable IP address or DNS name. Instead, I am using Group Policy to force the connections to be over RDP instead of SSL. \Computer Configuration\Policies\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Security\Require use of specific security layer for remote (RDP) connections The Windows 7 user now gets a much less stern warning that "the server's identity cannot be confirmed" which I can live with. I don't have enough control over the end-user's machines to ask them to install a new root certificate either. TS1 and TS2 are also load-balanced using the Session Broker, which is installed on the Gateway Server. I am using round-robin DNS, so the user's initial connection will go via Gateway1 to either TS1 or TS2. TS1/TS2 will then talk to the session broker and may pass the user to the other server. I.e. the user may get connected to TS2, but after talking to the session broker the user may be passed to TS1, which is where they will run their session. When this switching of servers happens, in my setup, the screen sits with the word "Welcome" for 20-30 seconds after which it flickers, Welcome is shown again and then flashing through nthe normal login screens (i.e. "wait for user profile manager" etc). Having done some research, I think what is happening is that the user is being fully logged on to TS2 (while "Welcome" is shown) before being passed to TS1, where they are then logged in again. It is interesting that normally when you see the ""Welcome" word, the little circle to left rotates. However, it does not rotate during this delay - the screen just looks frozen. This blog post leads me to think that this is because CredSSP is not being used, probably because I am disallowing SSL and forcing RDP. What I have tried I enabled SSL again which removes the "Welcome" delay. However, it seems to introduc a new delay much earlier in the process. Specifically, when the RDP client is saying "initialising connection" - this is now much slower. Quite apart from the fact that my certificate problem precludes me using that solution without considerable difficulty. I tried disabling the load balancing (just remove the servers from the session broker farm) and the connections do not have any delay. The problem is also intermittent in the sense that it only happens when the user gets bumped from one server to another. I tested this by trying to connect directly to TS1 (via the Gateway, of course) and then checking which server I actually got connected to. Just to be sure, I also by-passed the round-robin DNS to see if it had any impact and it doesn't. The setup is essentially in line with MS recommendations here: TS Session Broker Load Balancing Step-by-Step Guide I tried changing to using a dedicated redirector. Basically, rather than using a round-robin DNS, I pointed my DNS to the Gateway server and configured it to be a dedicated redirector (disallow logons, add it to the farm). Same problem, alas. Any ideas or suggestions gratefully received.

  • How do you organise the cables in your racks?

    - by Tim
    I'm migrating my current half-size rack to a full-size rack and want to take the opportunity to reorganize and sort our spaghetti-hell of ethernet cables. What system do you use for organising your cables? Do you use any tracking software? Do you physically label the cables? What are you identifying when you label each end? Mac address? Port number? Asset number? What do you use to label them? I was looking at a hand held labeler, but the wrap around laser printer sheets might work. The Brady ID PAL seems good, but it's pricey. Ideas?

  • PHP throwing XDebug errors ONLY in command line mode...

    - by Wilhelm Murdoch
    Hey, all! I've been having a few problems running PHP-based utilities within the command line ever since I enabled the XDebug. It runs just fine when executing script through a browser, but once I try an execute a script on the command line, it throws the following errors: h:\www\test>@php test.php PHP Warning: PHP Startup: Unable to load dynamic library 'E:\development\xampplite\php\ext\php_curl.dll' - The specified module could not be found in Unknown on line 0 PHP Warning: Xdebug MUST be loaded as a Zend extension in Unknown on line 0 h:\www\test> The script runs just fine after this, but it's something I can't seem to wrap my head around. Could it be a path issue within my php.ini config? I'm not sure if that's the case considering it throws the same error no matter where I access the @php environmental variable. Also, all paths within my php.ini are absolute. Not really sure what's going on here. Any ideas? Thanks!

  • MySql Data Loss - post mortem analysis - RackSpace Cloud Server

    - by marfarma
    After a recent 'emergency migration' of a RS cloud server, the mysql databases on our server snapshot image proved to be days out of date from the backup date. And yet files that were uploaded through the impacted webapp had been written to the file system. Related metadata that was written to the database was lost, but the files themselves were backed-up. Once I was able to manually access the mysql data files before the mysql server started (server was configured to start mysql on boot), I was able to see that the update time for ib_logfile1, ib_logfile0 and ibdata1 was days old. As with this poster, mysql data loss after server crash, it's as if some caching controller had told the OS / mysql server that it had committed data that was still in cache, and it was lost instead of flushed. I can't quite wrap my head around how the uploaded files got written but the database data did not. I would have thought that any cache would have flushed system wide, rather than process by process. Any suggestions as to how this might have happened?

  • Prevent auto mounting Android sdcard under Linux Mint

    - by BullShark
    I recently obtained an older Android phone, so that I could test Android Apps on it. I've needed it because I have a Nexus 7 but not older Android versions, hardware, etc. to test on. I'm having a problem with it under Linux Mint with Cinnamon. When I plug the phone in, or remove and plug the sdcard from the phone back to it while the phone is plugged in, Linux automatically mounts the sdcard. This is a problem because once it is mounted under Linux, it dismounts from the phone running Android 2.3.5, and I can no longer test Android Apps I write that require the sdcard to be present, writable. I went to Menu System Tools System Settings System Details Removable Media, and it brings up this window. I have changed the settings to always "Ask what to do" on "Select how media should be handled". However, the sdcard still gets mounted and then I am asked how I want to open these files (media players, photo importers, file browser, etc.). If I click the checkbox for "Never prompt or start programs on media insertion", then the sdcard is mounted, and I am not asked how to open these files. Eject is just a noob word for Ubuntu users that means umount (unmount) like "Adminstrator" is another ubuntu noob word for the root user. And if I unmount the sdcard, the phone doesn't recognize it again until I take the sdcard out and plug it back in. The phone sees it for a brief moment until Linux Mint takes it over. There are 2 possible solutions and maybe more: 1) Prevent Linux from automounting sdcards some how 2) Tell Android not to allow the computer it is plugged into to take over the sdcard, HOW? Edit: I found out how to prevent the sdcard from being automatically mounted: Now it gets recognized by Linux: bullshark@beastlinux ~ $ dmesg | tail -n 25 [597212.218323] sd 21:0:0:0: [sde] Attached SCSI removable disk [597212.218639] sr 21:0:0:1: Attached scsi CD-ROM sr2 [597212.218910] sr 21:0:0:1: Attached scsi generic sg7 type 5 [597217.139373] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597217.140726] sd 21:0:0:0: [sde] No Caching mode page present [597217.140735] sd 21:0:0:0: [sde] Assuming drive cache: write through [597217.143595] sd 21:0:0:0: [sde] No Caching mode page present [597217.143602] sd 21:0:0:0: [sde] Assuming drive cache: write through [597217.152240] sde: sde1 [597389.751008] 4:2:1: cannot get freq at ep 0x84 [597390.238742] 4:2:1: cannot get freq at ep 0x84 [597624.903132] sde: detected capacity change from 1977614336 to 0 [597637.677763] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597637.679616] sd 21:0:0:0: [sde] No Caching mode page present [597637.679626] sd 21:0:0:0: [sde] Assuming drive cache: write through [597637.682508] sd 21:0:0:0: [sde] No Caching mode page present [597637.682515] sd 21:0:0:0: [sde] Assuming drive cache: write through [597637.692758] sde: sde1 [597661.857979] sde: detected capacity change from 1977614336 to 0 [597688.775455] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597688.776814] sd 21:0:0:0: [sde] No Caching mode page present [597688.776823] sd 21:0:0:0: [sde] Assuming drive cache: write through [597688.780055] sd 21:0:0:0: [sde] No Caching mode page present [597688.780062] sd 21:0:0:0: [sde] Assuming drive cache: write through [597688.788639] sde: sde1 bullshark@beastlinux ~ $ However, the phone still unmounts the sdcard upon being detected by Linux.

  • Bash color prompt and long commands

    - by Eric J.
    I'm colorizing parts of my bash prompt using ANSI escape sequences. This works great, until the command I'm currently typing in is long enough that it has to wrap. Instead of the rest of the command displaying on the next line, it wraps back to column 1 of the current line, overwriting the beginning of the prompt. I get that behavior with this prompt: export PS1="[\u][\033[0;32;40mdemo \033[0;33;40m1.5.40.b\033[0;37;40m] \w> \033[0m" but it works correctly with the same prompt, ANSI sequences remove: export PS1="[\u][demo 1.5.40.b] \w> " I'm connecting using the current version of Putty, with default Putty settings. The OS is Ubuntu 8.10.

  • Windows Live Family Safety Service keeps closing Start Menu

    - by Jim McKeeth
    Got my kids a new Toshiba Laptop for Christmas. I was setting it all up for them so it would be ready to go. Tonight I installed Windows Live Family Safety Parental Controls. In the process of testing I discovered that on all the accounts the Start Menu closes automatically within 3 seconds (or less) of opening. It seems that it happens every 3 seconds, so sometimes it is immediate, and if I open it again then it will stay open for a full 3 seconds. This of course is rather annoying, and I need to wrap it up so it is ready to go under the tree. I disabled the Windows Live Family Safety Service, and that fixed it. Enable it again and the behavior returns. Is this a feature of the service? Can I disable that feature and keep the other features?

  • Public IP Routing over Private GRE tunnel

    - by Paul
    I have a GRE tunnel configured between two linux boxes. The tunnel works fine. I can ping from each host the other private ip. Head privateip: 10.0.0.1 publicip: 8.8.8.8 Tail privateip: 10.0.0.2 publicip: 7.7.7.7 The public IP on Tail has the network block 9.9.9.0/23 statically routed over the 7.7.7.7 interface. The idea is to make the 9.9.9.0/23 ips work on servers on the 8.8.8.8 network. I configure the tail host to route the /23 block. I mounted a 9.9 IP on the head server. I can ping the 9.9 ip from the tail to the head. I can't ping the 9.9 ip from the public internet. I think I need to add some other routes because of gateway issues, but I can't seem to wrap my mind around it (not a router guy, just beating my way through something that I have never done before and vaguely understand) --danks

  • SBS 2003 no network connection and acting strangely a bunch of Event ID 13568

    - by JMan78
    I've got an SBS 2003 Standard server and it was running fine until earlier today when it was rebooted, after the reboot it has no network connection, I can't seem to right click on a lot of stuff and get dialog boxes, I can't launch IE, it's acting extremely strange. We are dead in the water at this point. I checked the event logs and noticed we're getting a ton of Event ID's 13568. I thought it was a Journal Wrap error, and while I was going to try to fix it using this article: http://support.microsoft.com/kb/290762 I can't even do that because after I set the D4 value, then went to restart NTFRS from command prompt and I got the following: System Error 1059 has occurred. Circular service dependency was specified. That is where I'm at and haven't been able to figure anything else out. ALso, I've posted this on EE, there are some screens of event logs and such there: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/SBS_Small_Business_Server/Q_27969593.html

  • How can I poll different aws sqs in the same process?

    - by Luccas
    What is the right way to poll from differents AWS SQS in the same process? Suppose I have a ruby script: listen_queues.rb and run it. Should I need to create threads to wrap each SQS poll or start sub processes? t1 = Thread.new do queue1.poll do |msg| .... end t2 = Thread.new do queue2.poll do |msg| .... end t2.join I tried this code, but the poll is not receiving any of the messages available. When I run only one of them (t1 or t2), it works. But I need the 2 running. What is going on? Thanks!!

  • Using Linode as a proxy server wrapped in DNS to bypass paid internet services

    - by snihalani
    I have a linode server that I use for development. I was thinking of using that as a proxy server. I have noticed that most paid connections allow DNS queries but don't allow http until I pay them. I verified this by flushing my dns cache and nslookup some random websites. How do I create a proxy server that allows me to may be wrap my packets from my computer in DNS packets, relay to my linode server with ssh key authentication and act as a broker? Thanks.

  • Color Temperature in PowerPoint 2010

    - by Otaku
    I'm teaching PowerPoint 2010 and it's got some great new features. Unfortunately, one that I can't wrap my head around is the the new "Color Temperature" feature for pictures. I do understand color temperature in general (i.e. the lower the number, the "colder"/"oranger" - the higher the number, the "hotter"/"bluer"). The way PowerPoint implements it seems opposite from most other programs - like Photo Filter in Photoshop. So I need to understand what this feature is in more detail so I can explain it to my students. Does anyone know?

  • Which protocol do clients use when communicating with servers in a SAN

    - by Mario De Schaepmeester
    I'm trying to wrap my head around how a SAN works and how it is implemented. If I understand this well, clients wanting to access the storage devices in a SAN need to communicate with the servers via the LAN. When the SAN is implemented with Fibre Channel, these servers are Fibre Channel compliant devices, and internally in the SAN they work with the Fibre Channel Protocol. Both data and communications are supported by Fibre Channel. But which application-layer protocol do the clients use in the LAN to communicate with the servers? Is the data simply transferred via ethernet as well? This is some part I am stuck on. I went trough a lot of sources but most sources don't really mention protocols and if they do, they only mention FCP.

  • Sftp via shell - how it is possible

    - by Tomasz Zielinski
    (Moved from StackOverflow: http://stackoverflow.com/questions/4589725/sftp-via-shell-how-it-is-possible) How is it possible for tools like http://mysecureshell.sourceforge.net/ to provide SFTP access by merely specifying them as shell by typing: usermod -s /bin/MySecureShell myuser ? I'm on Debian Lenny, with default sshd/OpenSSH. Is this e.g. a feature of SSH protocol that allows user shell to handle sftp commands? I can't wrap my head around this because usually OpenSSH needs sftp-server module (or the internal one in newer versions) - and this makes me think that sftp commands don't even hit the shell and are handled earlier or by different code path..

  • Can I make ssh tell me which control file it would use for multiplexing?

    - by Ryan Thompson
    I am using the following options in my ~/.ssh/config in order to enable connection multiplexing: ControlMaster auto ControlPath ~/.ssh/control/master-%r@%h:%p However, this has the annoying problem that the first shell to connect to a particular server must be the last to disconnect, because it is the master connection that all the other connections are using. So if you log out of the master, it appears to just hang. To solve this, I would like to wrap ssh with a script that checks if the control master file exists, and if not, starts a master ssh process in the background. Then it would start a slave ssh session. In order to accomplish this, my script would have to determine the path to the control file that ssh would use. This would entail parsing the ssh command line options and config files and implementing the logic for determining the ControlPath. Is there any way to just ask ssh what path it would use, so I can check it?

  • How to pass an argument to a Windows Scheduled Task with spaces in it

    - by Rodney
    I need to set up a Windows Scheduled Task. It accepts 1 parameter/argument which is a path and can contain spaces. My Scheduled task does not work - it "breaks" the parameter up at the first space. If I run it in the Command Prompt I can just wrap the argument in " " and it works fine, however, this does not work in the Scheduled Task UI. e.g. C:\Program Files\xyz\FTP File Transfer\FTPFileTransferTask.exe "C:\Program Files\xyz\The Interface\Folder Path" I have tried wrapping the argument with " " ' ' [ ] () and have tried filling in the spaces with %20, ~1 etc. with no luck. I know of one solution to make a bat file and use " " around my argument but I don't want to add more complexity. I tried it on Windows 7 and Windows 2008 Server and both failed. There seems to be no discussions on this?

  • Bare minimal Chef provisioning and deployment?

    - by Andrew McCloud
    I've read the documentation on Chef twice over. I still can't wrap my head around it's concept because they skip but fundamentals and jump to complex deployments with chef-server. Using chef-solo and possibly knife, is there a simple way to provision a server and deploy? I may be wrong, but it seems like with my cookbooks prepped, this should be very simple. knife rackspace server create --flavor 1 --image 112 That provisions my server. I can optionally pass --run-list "recipe[mything]", but how do my cookbooks in ~/my_cookbooks actually get on the server? Do I have to manually transfer them? That seems counterproductive.
