• Windows 7 + Bind on Ubuntu - DNS keeps stopping

  - by fistameeny

  I have a Bind DNS server running from Ubuntu 12.04 LTS Server 64 bit. In there, I've setup some local A records for internal websites, e.g. wiki.domain.local. Everything works fine, except that every so often (a few times a day), the DNS stops responding on client machines (running Windows 7). The only way I've found to fix it is to stop/start the dnscache service on the Windows machine. Sometimes if I just wait for a few minutes, the DNS will start to work again. I've checked the Windows event log and can't see anything relevant. I've also had a look in the Bind logs and can't see anything there. Has anyone experienced this before?

• Merge Publication Data Partition Snapshot generation

  - by David Osborn

  I have a merge publication in SQL 2008 R2 with data partitions and I am wondering when I should generate the snapshots for the data partitions. I get an error sometimes when bringing a new subscribe online related to the partition snapshot being out of date and I am wondering if this has to do with the publication snapshot being scheduled at the same time as the partition snapshots. I'm not really sure how the partition snapshot gets generated, but it appears maybe it is getting generated before the publication snapshot. If this is the case how should I be scheduling the partition snapshots to get generated? Should I set them to run x number of minutes after the publication snapshot? this seems kind of poor to do in case the publication snapshot takes awhile or fails. It seems to me the publication snapshot should just run the data partition snapshot agents when it is done if this is the case.

• Stop a Windows XP taskbar item from blinking forever

  - by EMP

  In Windows XP when an application that doesn't currently have the focus wants to attract the user's attention its Taskbar item blinks. Often it blinks 3 times and then stops, which is fine. However, sometimes it just keeps blinking forever. An example of that is Firefox with a new JavaScript confirmation dialog. This is really annoying if I don't want to switch to that application just now - I basically cannot focus on anything else because of this stupid blinking thing distracting me! How do I force all apps to blink only 3 times (or X times) and then stop?

• server performance metrics report and practicality

  - by Anjesh

  I have a need of preparing web server (apache-php) performance report containing important metrics like CPU usage, disk io, memory usage on user basis. Couple of domains are hosted in the same server and they run from separate users using fcgi. The reason being sometimes some hosted applications take lots of cpu usage, making the server slow for other applications (running as separate users). i am planning to develop scripts for this, as i can't seem to find any simple utilities for this purpose. This script will take snapshots of the user wise metrics at defined periods say 15 minutes and record it. Any abnormalities will be reported via emails. How practical is that? also would be interesting to know what else need to be recorded.

• How to allow simple file sharing on Windows Server 2008R2 through VPN

  - by Martin Wiboe

  We are a small, distributed company with a Windows Server 2008R2 installation. I would like to set up a way for our employees to connect securely to this server via VPN and then be able to map a network drive. I have gotten this to work somewhat by installing the Network Policy and Access Services Role on the server and using the default settings. I have also created a network share on the server. The problem is that our connectivity is sporadic (sometimes the service stops listening on the port or simply refuses to authorize correct credentials) and slow. I can always connect through VPN, but mapping is problematic. I would be grateful for the answer on how to accomplish this as well as some guidance on whether I am on the right track. Thanks in advance!

• Force ID of user created by apt-get

  - by Bart van Heukelom

  Context: I'm automatically installing postgresql-9.1 on an Ubuntu server with apt-get. This creates the required postgres user. The Postgres data is on an external volume that survives reinstalls. This data is obviously owned by the postgres user. The problem I'm having is that the ownership is not recorded under the name postgres, but under the UID that postgres had at creation time. When the server is reinstalled, postgres sometimes gets a different UID, and no longer owns the data directory, and thus does not work. Question: Can I force the UID of the user postgres created by apt-get to something fixed? Or is there another way to solve my problem? (As you may have deduced, this is on Amazon EC2 with the data on an EBS volume)

• Connect to a particular network connection from terminal

  - by RanRag

  I am currently using Reliance netconnect USB modem. The problem I am facing is my USB modem disconnects itself at 22:00 PM IST everyday. Now, sometimes what I do is start some downloading and leave my laptop for 2-3 hours in this case if my network disconnects it is a problem for me. So, what I used to do in windows is make a python script and execute rasdial myconnection_name to automate the connection process in my absence. Now I want to achieve something similar in linux. So, what are my alternatives for rasdial like tool in linux to automatically connect to a particular connection . I am using ubuntu 12.04 and here is my nm-tool output.

• Why do mapped drives only reappear after logging out and back in, and not after a reboot?

  - by razumny

  I work in a corporate environment, where we use mostly Windows 7 Professional computers, though some legacy applications are still being run on Windows XP. We have security in place on the network not to allow access to network resources to computers that are not members of Active Directory. When logging in, our users get their home folder and a common network drive mapped to H: and F:, respectively. Sometimes, this does not happen, and the drives are not mapped. The solution is to have the user log off, and back in to Windows. If they reboot, the drives remain unmapped. Does anyone know why this may be?

• Python/Lesta.A worm

  - by Hanks

  My Nod32 have been catching something that is apparently identified as Python/Lesta.A worm. No matter how many times I tell Nod32 to delete and quarantine the file, it always re-appear, the situation will repeat about 3-4 times a day. This thing has been creating a folder called "pamela" in one of my drives, it sometimes also creates a "xxx.folder" file, which Nod32 identifies as "Exploit/CodeBase virus". I have Googled, and done pretty much everything related to this: a full scan in safe mode with no networking turned on, and also ran Ad-Aware, SpyBot, SpyHunter, ComboFix and cleaned the registry. Any idea how I can completely get rid of this annoying virus/worm?

• 301 redirect, canonical question

  - by Dave

  I've designed my own 'latest news' page for my site - and I'm trying to keep the URL's clean. (eg) It should look like this : http://www.domain.com/21/this-is-a-clean-url/ When someone links to the article, they sometimes mess it up and do : http://www.domain.com/21/this-is-a-clean-url/#random-hash-tag So what I have been doing is looking for "http://www.domain.com/21" and 301 (moved permantly) redirecting to the proper url + adding a canonical meta tag for it. Is this going overboard? Should I instead be using a (302 Found) header - and just let the canonical tag tell search engines what the proper URL for the article is? What is the best way of handling this?

• Putty freezes at random when logging into a remote machine in another continent

  - by artknish

  I have to ssh to a remote machine in Europe from Asia every day for my work. But Putty freezes sometimes at totally random times and I have no choice but to close and re-open a new ssh session. It's frustrating especially when I'm editing something or executing a long running program. I know the question really doesn't have much details ('cause nothing seems to be wrong with the network at all). Has anyone experienced this sort of issue with Putty and had resolved it? Thanks for your time!

• Windows: Should I install Server or stick with regular?

  - by stalker92

  I hope somebody can help me solve my dilemma. I have my home PC (using Windows 7) which I use for both work and leisure (gaming, surfing, movies etc.) I tend to never turn it off, only when I must reboot because some installation requires me to or when the power gets lost. But, sometimes Windows starts acting weird (usually after the long period of system uptime), per example eats up randomly all the space on my system partition etc. which is solved after the reset by itself. I was thinking to switch to Windows Server, I guess that it is more optimized for long uptime, well, obviously it is meant for use on servers. Can somebody with more experience with this help me decide is it worth it, will it solve these issues connected with long uptime periods? Thanks in advance.

• Options for transparent data encryption on SQL 2005 and 2008 DBs.

  - by Dan

  Recently, in Massachusetts a law was passed (rather silently) that data containing personally identifiable information, must be encrypted. PII is defined by the state, as containing the residents first and last name, in combination with either, A. SSN B. drivers license or ID card # C. Debit or CC # Due to the nature of the software we make, all of our clients use SQL as the backend. Typically servers will be running SQl2005 Standard or above, sometimes SQL 2008. Almost all client machines use SQL2005 Express. We use replication between client and server. Unfortunately, to get TDE you need to have SQL Enterprise on each machine, which is absolutely not an option. I'm looking for recommendations of products that will encrypt a DB. Right now, I'm not interested in whole disk encryption at all.

• Windows IPSec computer authentication using *user* account?

  - by Tim Brigham

  For some reason every once in a while it happens that my IPSec authentication is from a user account to a computer account, not computer to computer. How can I fix it? Sometimes - notably when I try to add a new workstation through ePO but it's happened other times as well I'm getting strange behavior from my Windows Advanced Firewall IPSec. This causes the authentication to be invalid (as the group memberships, etc all assume computer accounts). I have no idea why this is happening or how to fix it but the IDs to match up between servers (the opposite server in my second example has remote ID timb).

• How do you handle the task of changing the schema of a production MySQL database?

  - by Continuation

  One of the biggest complaints I have heard about MySQL is that it locks up a table if you try to change its schema like adding a column or adding an index. By "locking up the table" does it mean I can neither read nor write to the table? Sometimes for hours? That seems a pretty severe limitations. I was going to use MySQL for my new project but this gives me pause. Is there a workaround for this? How do you handle the task of changing the schema of your production MySQL database? By the way someone told me Postgresql doesn't have this problem. Is that true - I can both read and write to a Postgresql table while changing its schema? Is there any performance penalty incurred? Would love to hear your experiences.

• How can I get rsync to ignore missing files?

  - by Joe Casadonte

  I'm executing a command like the following to several different systems: $ rsync -a -v [email protected]:'/path/to/first/*.log path/to/second.txt' /dest/folder/0007/. Sometimes *.log does not exist, and that's OK, but rsync generates the following error: receiving file list ... rsync: link_stat "/path/to/first/*.log" failed: No such file or directory (2) done Is there any way to suppress that? The only way I can think of is to use include and exclude filters, which just seem a PITA to me. Thanks!

• Feedback on available mid-to-enterprise level desktop backup solutions [closed]

  - by user85610

  I am involved in the creation of a new backup solution to replace our current Retrospect setup, which has become a significant time sink to administer. We have almost 200 desktop and some laptop clients, both Windows and OS X. We're only interested in products oriented around disk-to-disk, and would be integrate well with our current set of nine NAS devices as target storage. I'd just like some feedback from anyone out there, as it's sometimes difficult otherwise to find objective reviews of software at this level. Both data and time are important enough that we need a reliable solution which won't be prone to self-destruction as often as Retrospect. Bonus points for de-duplication, which might help squeeze more service time out of our NAS setup in terms of capacity. Currently considering Commvault and Netbackup. Many other products I've seen don't have an OSX client. Any thoughts?

• Snow Leopard - Dock icons randomly disappear

  - by lostInTransit

  Snow Leopard works great! My mac's really fast after this. But sometimes the dock icons just disappear! I see the blue dot beneath when I click the empty space. So I know the item's there. But there are no icons! This happened for Safari and Downloads. Some people responded on the Apple forums that I should try and remove the dock's plist file. But this just restores the dock to its original settings! I don't want to lose my settings. Anyone else facing this issue with SL? Or is it a problem only I am facing? Thanks

• Small font all 'new' messages suddenly in Gmail on Ubuntu in Opera, why?

  - by Michael Durrant

  This seemed to happen out of the blue. I have been using Opera for years. I can't find anywhere in Gmail to change the default font that is used in Opera. Ubuntu is Version 11 Opera is version 11.6 In Firefox the font is normal size. I have tried playing around with both all the browser setting I can find plus Ubuntu system settings (I had seen some mentions of Opera using the system default font sometimes) but no success so far. Really bumming as I have been using Opera for two years and if I can't resolve it I will not be able to use it. I can switch to Firefox but I don't want to.

• Troubleshooting an iMac

  - by Matthew

  What can I do to fix my iMac? When I start it up, it just loads forever (never getting to the Desktop). The mouse will appear then disappear, then the loading bar will sometimes appear and then disappear and it just goes in circles forever. If I start up in safe mode (by holding shift), it gets to the login window. However, if I attempt to log in the login window disappears and reappears asking for my password again. What can I do to troubleshoot this?

• SQL server availability issue: large query stops other connections from connecting

  - by Carlos

  I've got a high-spec (multicore, RAID) server running MS SQL 2008, with several databases on it. I have a low throughput process that periodically needs a small amount of information from one of the DBs, and the code seems to work fine. However, sometimes when one of my colleagues does a huge query against one of the other DBs, I see full CPU usage on the machine, and connections from my app time out. Why does this happen? I would have thought the many cores and harddisks would somehow (together with cleverly written DB server) be able to keep at least some of the resources free for other apps? I'm pretty sure he doesn't use multiple connections for his query. What can I do to prevent this?

• Solaris 10 5/09 can't find SATA disk

  - by anon

  We need to run standard Solaris 10 on a few development servers (Dell 530s) because we can't get a commercial application running on OpenSolaris (we're still trying). However, we are finding that sometimes when Solaris 10 goes to do the install, after setup screens, it can't find the SATA drive. We tried the BIOS setting described here: BigAdmin On some Dells 530s, Solaris GA installs fine, but on others it doesn't. OpenSolaris always installs. Is there some way we can determine (eg. installing OpenSolaris and examining the SATA driver used) what OpenSolaris detected and use some option or driver from it to get Solaris 10 installed on our development Dell servers?

• I want to run a script when known bluetooth device connects/disconnects to WinXP

  - by Rope

  I have a laptop on my desk at work. I have screensaver timer enabled, so if I'm not using the computer for ten minutes, it will start the screensaver. I also have "On resume, password protect" option checked. This is useful and I want it to be so. However, sometimes I just sit at my cubicle and read some documents without touching the computer. During that time I want my computer to know that I'm there and that there is no need to start the screensaver. I have a mobile phone that is bluetooth paired with the laptop for synchronizing calendars. Is there some way for a script or a program to know that any (or specified) paired device is connected? While typing this out I thought that there might be some registry entries for this. Does anyone have any thoughts on this? -Rope

• Language bar switched input types on me.

  - by Elijah

  I learned Japanese, but I'm not native to Japan, so I never had a Japanese keyboard. I used to use the language bar to go back and forth between English and Japanese, simply typing the words in romaji and having windows convert it into either hiragana, katakana and sometimes Kanji. Suddenly, my input type changes. I am no longer able to simply type in English, it changed my keyboard into a native Japanese keyboard, and what's worse it doesn't even allow me to write in hiragana, which I would need way more than katakana. Can anyone tell me how to restore it to the old setting where I simply chose what the output dialect would be, and typed the words phonetically in english and have it translate the sounds for me into japanese characters?

• Custom Transport Agent: How do I collect NDRs and all other undeliverables in Exchange 2010 from the Postmaster?
