• Mail Stuck in Backend Exchange Queue

  - by Kyle Brandt

  I have a message that has and is stuck in a queue on my backend mail server. The queue is: Internet Mail SMTP Connector (MY_FRONT_END_SERVER_NAME)-524350ff... It is in state retry with 183 failures. It is only one message and all other mail is flowing. The message is not particularly large. My limited understanding, a guess really, is that this message should get handed off to the front end mail server and sent to the remote hosts for which it is destined, so it should even matter if the remote host is up. However, I can telnet to the smtp provider of that host. How can I find out why it is stuck in this queue, and can I force it out somehow (unfreeze doesn't help me)?

• On Windows 7, how to Shut Down the computer without the Update?

  - by Jian Lin

  Sometimes when my Win 7 machine has programs that crashed, maybe Firefox, or IE, I would like to shut down the computer without installing any Windows update. That's because I worry that if IE or Firefox crashed, the system is not in a very stable state, so I would rather install the update later. But it seems I only have 2 choices: 1) Shut Down and it always will do any Update 2) Restart, and no update is done (these are 2 choices among the shut down / log off option) So is there a way to Shut Down without doing the Update? Or must I restart first, and then do the Updates, and then Shut Down?

• MariaDB, Galera, xtrabackup - do I need the binary log?

  - by bernhardrusch

  We are using a MariaDB Galera Cluster with 3 nodes. For the state transfer we are using xtrabackup. We have some problems with the binary logs - they got too big and crashed the server. We can remove them manually with the purge binary logs command, another way would be to set the expire_logs_days so they would expire. I now that we could use xtrabackup to backup the DB and use the binlog to get to some point in time. But do we really need it for Galera to work ?

  - by leo

  I am try to deploy a jar to an jboss server. It works on my environment. But when I deployed the same jar on another server, i kept getting an error saying that the persistence unit is already registered. There is no other bean using the same name and the same persistence unit name. I tried to restart the server and remove the tmp, work, data directory but still get the same error. here is my error: ObjectName: jboss.j2ee:service=EJB3,module=wess_jpa.jar State: FAILED Reason: java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:unitName=dses_wess already registered.

• Windows 7 Pro x64 suffering from insomnia

  - by gemisigo

  My Win 7 Pro x64 is unable to enter sleep mode. Pressing the sleep button results in strange state where the computer starts entering the sleep mode, the display is turned off but then the whole process stops, it does not switch off the hdd, the keyboard still responds to numlock/capslock, but the display does not on anymore. I have to cut power and restart. If I remove everything (wireless mouse, external hdd, usb hub, etc.) it does enter sleep mode, but if there is something left, it does not, though every one of them has "Allow the computer to turn off this device..." checked and "Allow this device to wake the computer" unchecked. Why does it not work? It was working properly in the RC.

• Can I set a hyperlink's display text from a document property?

  - by themel

  I'm trying to make a word document customizable through a document property that contains the base URL of all the links. I've managed to make the links themselves reference the document property like this: { HYPERLINK { QUOTE "http://{ DOCPROPERTY Host}/some/path" } } Changing the document property and updating the files makes the hyperlinks point to the correct URL. However, visually, nothing changes - the old URL is still shown as the display text of the hyperlink. Is there a way to make this work? Microsoft docs helpfully state You can edit the display text for the field by typing over it. but I can't figure out how that is supposed to work - even if I manually type over the hyperlink, it includes the edits in the field code instead of adjusting the display text. Currently attempting in Word 2002, but 2010 also available.

• Crap, hard disk failure. Can I recover my "move"d folders?

  - by Doug

  I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

• How to kill an openvz container?

  - by johannes

  An openvz container can be stopped with vzctl stop <id> , but this needs the cooperation from the init inside the container. In case a container is compromised a way is needed to stop the container withouts its cooperation. Something like a vzctl kill <id> is needed which kills all processes inside the container and puts it into the stopped state. Such a kill command is not listed in the manpage. How can an openvz container be killed/stopped without needing it's cooperation?

• App to watch installer and roll back host later?

  - by OverTheRainbow

  I'm looking for a Windows application that can watch everything an install programs does to Windows, and can roll it back to what it was like before installing an application. InCtrl5 is useful to know what an installer did, but doesn't provide a way to return the host to its previous state. I'd like to avoid having to restore a host using eg. CloneZilla just for a small application. The goal is to make it fast to test an application in a test lab. Does someone know of an application that can do this? Edit: I wasn't specific enough: I need a way to totally remove an application but keep all other changes I made after installing the application. Edit: After checking a few of them, I settled on Cleanse Uninstaller, which was capable of removing the whole of an application, although it doesn't watch when it's installed.

• is there a cheatsheet for linux commands to save your system?

  - by Asaf

  I've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP) ..The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace) I feel like a really need like a "rescue" cheatsheet for things like "how to save the X no matter what without pressing reset" and "how to reset the system to "normal state"" "how to connect to the internet through the command line" "how to monitor what the X is doing" (using ubuntu linux 10.04 btw)

• Revert a VM client from within the VM Client - is it possible?

  - by Saariko

  I am creating a test VM client for our QA department. Once it's installed, my options will be: Use a snapshot Use non persistent disk on the hard disk. For either options, I can give the role of QA_DEP the ability to log to vCenter and go back/power-off the client - so they can return to their clean machine. My question: is it possible to have that ability without using vCenter? What If I want that on a Client reboot - it will return to it's initial/clean state? The clients are not gonna be heavy loaded.

• Windows 7 Sleep Problems

  - by salcan

  My desktop's Windows 7 installation was working perfectly but recently I ran into a problem where it would not come out of sleep. The system seems to be running it's just that it won't come out of the sleep state. If I have to guess I would say that it's not recognizing the USB and thus not waking. I'd say this was a standard problem with Windows not sleeping/hibernating properly, but it was working fine for about a year and stopped working around two weeks ago. I have hybrid sleep ON and USB selective suspend ON.

• Remove Windows 7's limitation on number of concurrent tcp connections (http web requests)

  - by Ghita

  I have an application that tries to open as many http requests as possible (in order to stress test a proxy implementation) It seems to me that Win7 (SP1) may have a limitation on number of concurrent opened connection (it may be the so called half-open state if I'm not wrong). Is there something I can do for client ? and also I test using a vista PC that acts as a proxy server. It would be great if I could configure it to sustain at least 50 new connections initiated / second on client side and many more on server. I made the modification according to this technet article by setting TcpNumConnections = 150 but it doesn't make a difference. I still only see about 20 tcp sockets associated with my http client by using tcpview.

• OSXplanet: Updating cloud images

  - by Turgs

  Hello I'm using OSXplanet (which is a mac app based on xplanet) to view satellite and rendered images of the earth (or other planets) as the desktop background on my laptop. The images and data refresh regularly as data is updated, such as cyclones, clouds, weather, volcanoes, etc. I have Cloud Data set to refresh every 3 hours, but the resulting image never changes. By default, OSXplanet seems to be trying to get image data from Iowa State University. Can I modify OSXplanet to set it to pull cloud image data from a different server location listed on http://xplanet.sourceforge.net/clouds.php? Thanks Turgs

• Simple server status page hosted externally available for users

  - by Chris

  I am looking for any kind of script - can be asp or php or any other web language - that gives me the ability to log outages and the current state of the network for our organisation. This would be similar to any major Telco's "Network Status" page, but I just want to tell the user's out there if the systems are up and running and have a history of recent outages. This would be for our remote user's so they could go to a webpage (externally hosted from our main site) and see that we are currently having problems with our network. What are other people out there using?

• How can I can delete a project in Aperture, but not in Flickr?

  - by jchatard

  I have a Macbook Air as my only computer ; I store my shots on Flickr. The size of the SSD doesn't allow me to keep all my RAW files on my laptop. So I publish the photographs I like in their final state on Flickr with the built-in feature of Aperture. When I hit delete on a project (in Aperture) the message clearly indicates that all photos synched to any service like Facebook, Flickr or any other will be deleted. How can I can around this without the hacky way of unlinking Aperture from Flickr before deleting the project?

• Fixing Broken Groups

  - by themaestro

  Hey, I just got onto a new project with the student government at my University and we're trying to get our webserver into a more workable state. The current problem is that all of us for some reason have sudo power on the server, but we can't write/create files anywhere on the server (as far as we can tell) currently. Our groups are currently as follows: /srv/ice/db$ groups goshri sshamim rmenezes goshri : goshri sshamim : sshamim ptx rmenezes : rmenezes ptx daifotis : daifotis ptx We added a few of us to ptx because we thought that might give us write access but it didn't. We have a bunch of webapps running on this server but since it's university things change hands quickly. What can we do to give us read access?

• Windows 7 is blocking ports

  - by Caleb1994

  I am trying to open port 80 and 3690 for HTTP and svnserve respectively. I have Windows Firewall off, and have tried temporarily disabling Mcafee VirusScan Enterprise, to no avail. According to http://www.yougetsignal.com/tools/open-ports/, both ports 80 and 3690 are still blocked. I can't think of what would be blocking them if Windows Firewall and my antivirus are disabled. Here is the output of netsh firewall show state Firewall status: ------------------------------------------------------------------- Profile = Standard Operational mode = Disable Exception mode = Enable Multicast/broadcast response mode = Enable Notification mode = Enable Group policy version = Windows Firewall Remote admin mode = Disable Ports currently open on all network interfaces: Port Protocol Version Program ------------------------------------------------------------------- 3690 TCP Any (null) 22 TCP Any (null) 80 TCP Any (null) 1900 UDP Any (null) 2869 TCP Any (null) Any help? I'm not sure what each item on the list of enabled/disabled items is, but "Operational Mode" is disabled, so I assume that one refers to me disabling Windows Firewall. I know that since Windows Firewall is off, this output might not be useful, but I figured I'd include it just in case, haha.

• Connecte RemoteApp to Exising Session

  - by Fowl

  Due to the slightly retardedness of an app I've got to run, I've got a server auto logging in on boot with the app on auto start. Remote desktop at my leisure to check on its status, etc. Gross, but it works. Now I've tried out RemoteApp which seems to work ok (ie. remotes the notification icon, balloons...) except for the fact that it creates a new session (and therefore instance of my app) - this confuses the heck out of app and it means that if I was using 'full' remote desktop I lose all my state. "Restrict each user to a single session" doesn't work. IIRC "Windows XP Mode" uses RemoteApp and it doesn't seem to have any trouble switching between modes. So how can I connect to a running app?
