• Securing NTP: which method to use?

  - by Harry

  Can someone good at NTP configuration please share which method is the best/easiest to implement a secure, tamper-proof version of NTP? Here are some difficulties... I don't have the luxury of having my own stratum 0 time source, so must rely on external time servers. Should I read up on the AutoKey method or should I try to go the MD5 route? Based on what I know about symmetric cryptography, it seems that the MD5 method relies on a pre-agreed set of keys (symmetric cryptography) between the client and the server, and, so, is prone to man-in-the-middle attack. AutoKey, on the other hand, does not appear to work behind a NAT or a masquerading host. Is this still true, by the way? (This reference link is dated 2004, so I'm not sure what is the state of art today.) 4.1 Are public AutoKey-talking time servers available? I browsed through the NTP book by David Mills. The book looks excellent in a way (coming from the NTP creator after all), but the information therein is also overwhelming. I just need to first configure a secure version of NTP and then may be later worry about its architectural and engineering underpinnings. Can someone please wade me through these drowning NTP waters? Don't necessarily need a working config from you, just info on which NTP mode/config to try and may be also a public time server that supports that mode/config. Many thanks, /HS

• What's throttling the database?

  - by Troels Arvin

  Hardware: Intel x86_64 with 192GB of RAM. OS: CentOS 5.4 x86_64. DBMS: DB2 v. 9.7.1 64 bit. During certain special workloads (e.g. parallel REORGs/RUNSTATs), I've seen the server transporting 450MB/s with 25000IO/s (yes, there is probably some storage system caching happening here) while all CPU cores were happily working in an even mix of usermode/wait. And disk benchmark tools can also bring some very satisfying bandwith and IO/s numbers to the table. On the other hand, we also have another scenario: A single rather complex query with at least one large table scan. db2's "list applications" reports that the query is Executing (not locked). IO: At most 10MB/s, 500 IO/s; CPU: two cores in 99.9% wait state, all other cores 100% idle. The tables which the query reads from have been altered to have LOCKSIZE=TABLE, so I would think that lock list work is zero. What's going on in such a situation? What tools/snapshots/... can I use to gain better insight in such a case?

• TFS 2010 Subfolder Permissions

  - by gmcalab

  I am a TFSAdmin and when I have a TFS project in which a subfolder needs specific permissions to deny some users. So, I right click on the folder in question hit Properties, and click the Security tab. There I select the Windows User or Group radio, then click Add. I put in the AD User that I want specific permissions for and hit Check Names. That resolves, so I click OK. Next, I select the permissions to Allow or Deny below in the Permissions for list. I hit OK. The permission are honored by TFS, this user no longer has PendChange permissions and I was expecting. The odd thing is, I was expecting to be able to go back into the Security tab and see that User in the list of Users and Groups and see the current state. But the list is always empty. Not sure why, but the permissions are definitely being honored, I can re-add the user with different permissions and those are also honored. Any ideas why the current users are not showing up in the Users and Groups list under the Security tab for a folder's properties? I also used the tf permission $\... to see if there were any permissions but it always returns There are no permissions set for this item (Inherit: Yes)

• nVidia performance with newer X and newer driver abysmal with Compiz

  - by Nakedible

  I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem. EDIT: In the end, nothing really worked, and I got really annoyed with the state of compiz and its support in Debian. Many nVidia driver revisions have passed and I am using Gnome 3 now, so I am accepting the best answers to this question even though the issue was not resolved.

• Enable bitlocker an save key to share

  - by user273694

  I have searched all over the web but cannot find a complete answer to this: How to enable Bitlocker on a laptop with TPM, and store a file with the Bitlocker recovery key and TPM password by USING THE manage-bde command line tool. The file should be the same as when created in the Bitlocker manager UI. I DO NOT want to save to AD. The same question was asked here but was not answered correctly. The goal is to write a script to be used with an endpoint manager. I have tried the following: manage-bde -on C: Works fine, but does not create or save a key. manage-bde -on C: -rk C:\myfolder\ and manage-bde -on C: -RecoveryKey C:\myfolder\ -rp The output from the last two methods state that a key has been saved to c:\myfolder and so on, but that is not the case. It also says that I have to: Save the password in a secure location Insert a USB flash drive with an external key file into the computer. Restart and run hardware test type "manage-bde -status" to check if the hardware test succeeded After a restart, I get an error saying that Bitlocker could not be enabled because the bitlocker startup key or recovery kpassword cannot be found on the USB device.... C: was not encrypted. Why am I asked to insert a USB?? I simply want to encrypt the hard drive and save the recovery information to a file automatically. Is that too much to ask? Help please!

• How to start MSSQL Server with corrupt model db

  - by Jordan McGuigan

  After moving some databases around (restoring, deleting, etc) we experienced an issue creating new databases. Specifically, When trying to create a new database MSSQL Server it failed because the "The database 'model' is marked RESTORING and is in a state that does not allow recovery to be run". As some online solutions suggested, we tried to Start and Stop the MSSQL Service. Service would not restart because "Could not create tempdb. You may not have enough disk space available. Free additional disk space by deleting other files on the tempdb drive" (FYI: the drive has 100gb of free space). Tried restarting the machine the MSSQL Server is running on. When the server came back online, we received the same error. We have tried deleting tempdb.mdf and restoring the modeldb from the templates folder, but neither of these solved the issue. We are unable to connect to the database, even in single user mode. Many of the online solutions have us running SQL commands against the server, but we are unable to connect (even in single user mode) to the DB to run commands against the server. Specific error messages: Database 'model' cannot be opened. It is in the middle of a restore. (Microsoft SQL Server, Error: 927) The SQL Server (MSSQLSERVER) service is starting. The SQL Server (MSSQLSERVER) service could not be started. A service specific error occurred: 1814. We need the server up and running again ASAP.

• Install multiport module on iptables

  I'am trying to install "fail2ban" on Cubidebian, a Debian port for Cubieboard (A raspberry like board).

• Change source address based on destination IP

  - by hgj

  We have several "router" machines that gather a lot of external IP addresses on the same host and redirect, NAT or proxy the traffic to the internal network. They also act as routers for the machines on the internal network. This works fine, however I am unable to make the routing table, so I can change the source address, based on the destination a machine from the internal network want to access. Let's say I have a router, that has public addresses P1 (5.5.5.1/24) and P2 (5.5.5.2/24). All traffic goes through P1, but if necessary, the host is reachable on P2 too. This looks like this and works fine: > ip addr ... 1: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether aa:bb:cc:dd:ee:11 brd ff:ff:ff:ff:ff:ff inet 5.5.5.1/24 brd 5.5.5.255 scope global eth1 inet 5.5.5.2/24 brd 5.5.5.255 scope global secondary eth1:p2 ... Now I want to use P2 as the source address, if I want to access the Google DNS service for example (8.8.8.8). So I add a row in the routing table like: > ip route add 8.8.8.8 via 5.5.5.254 dev eth1 src 5.5.5.2 > ip route ... default via 5.5.5.254 dev eth1 5.5.5.0/24 dev eth1 proto kernel scope link src 5.5.5.1 8.8.8.8 via 5.5.5.254 dev eth1 src 5.5.5.2 ... But this does not work. If I ping 8.8.8.8, the host still uses P1 as the source address, and does not use P2 at all for outgoing connections. Am I doing it right? I guess not...

• Windows Server 2012 licensing issue preventing RDP connections?

  - by QF_Developer

  I am witnessing an unusual behaviour on 1 of 5 Windows Server 2012 R2 machines (clean install) that is preventing any remote connections from being established via RDP. I have run through the prerequisites for RDP here but I am finding that any remote connection attempt instantly stops the "Windows Protection Service". When I check the event logs I see the following entry. The Software Protection Service has stopped Event ID: 903 Source: Security-SPP From what I have read Security-SPP is tasked with enforcing activation and licensing, it appears that RDP requires this service to be in the running state. Is it possible that I have inadvertently activated this instance of Windows with a key that has already been associated to another instance (We have 5 keys as part of an MSDN subscription)? Would this be sufficient to block RDP access? When I look under System Properties (Windows Activation) it states that Windows is activated and there are no other obvious indicators that there's a licensing issue. EDIT 1: I ran a Powershell script to display the product keys for all servers in order to check for any duplication. For the problematic server I am getting the message The RPC server is unavailable.

• Video card not detected in POST on initial boot.

  - by Jeff M

  I have a minor problem with my desktop computer after cleaning it out for dust. When I first boot up the computer, the video card does not get detected so I can't see anything. In POST, I'm getting the "can't detect video card" beeps. The boot sequence continues normally, just without video. However, if I restart it (using the restart button) anytime after POST, it would boot up normally. I have no reason to think that the motherboard, video card or PSU got damaged in the process. It was working fine before, works fine after resetting. Took all the necessary precautions while cleaning. On the initial boot, I can hear the video card's fan power up but immediately power down and try again one more time only to fail. After the beep, resetting gets everything running and sounding normally. I've reseated the card a couple of times and reset the BIOS but doesn't seem to help. I'm hoping I won't have to take it out and remove and reinstall everything again. Does anyone recognize these symptoms to know exactly what the problem is? My guess is that the video card isn't getting enough juice initially to be running stable to be detected. I just don't know what I did (or didn't do) to get it to be in this state. It's not a high priority thing for me at the moment, just means I have to always reset it after initially turning it on but will eventually remove everything and reinstall if it comes to that. I don't think the specs are relevant here but just in case, here's the relevant stuff: Motherboard: Gigabyte P35-DS3P Video: EVGA GeForce 8600 GTS PSU: Antec True Power Trio 650W Built ~2 years ago, still running well

• Is it possible to get ESC to behave as an actual escape key?

  - by leftaroundabout

  So I have finally switched, not so much because I'm yet convinced Emacs in itself is the better editor but because it certainly does have more powerful extensions. I am still using vim-mode though, perhaps that's part of my problem... but I really don't intend to abandon the modes-approach, so I'll probably stay with it. I'm getting along quite well, but one thing I find really unnerving is the behaviour of the esc key (which I have in the shift-lock position). I'm used to relying on this a lot as more or less a "panic key", which may not be nice but I find allows me to work generally quite a bit less caring about the keystrokes themselves, and thus faster. What I'd like this key to do is just get me out of any minibuffer or special editing mode into a well-defined normal state. Perhaps most importantly, I would like it to not do anything unrelated, Simulate meta. What do I have an alt key for? Close windows I'm not even in at the time. Getting interpreted as the final key in some key sequence. ... Is it possible to turn all that off and make esc an actual escape key? Vim-mode does make it behave kind of as I like in some situations, but when other plugins are involves this often breaks. Alternatively, are there different options that might suit my kind of workflow?

• How can I get Windows to apply its settings?

  - by Jouke van der Maas

  I have a computer with a major problem; it gives a blue screen when the login screen loads. I've been using this guide to troubleshoot the issue, and now I've run into a problem. I have determined the issue is not bad memory or a bad hard drive. According to the guide, this means the problem is in the OS. I've tried to follow the steps, but Windows (Vista SP1) somehow doesn't remember any changes. On every reboot, the computer is in exactly the same state it was in before. Any changes to system settings or files won't be recorded. As this means I can't check what is causing the problem, I can't fix my PC. Is there a way to find out what's causing this? Is it just a mode Windows goes into to protect itself, or is it some other problem? Anything to help troubleshoot will be of great help here. PS. I'm kind of new to this site. If I messed up, please tell me in the comments.

• Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

  - by Maxim Z.

  I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

• No sound out of headphone port

  - by Thanatos

  I cannot get sound out of the headphone port. Headphones are plugged in, and sound comes out of the internal speakers. Windows behaves normally (sound switches to headphones when headphones are inserted). It did work in Linux at one point, but something changed, we're just not sure what. Rebooting doesn't fix. This appears to occur whether or not PulseAudio is running. Things I've tried: Rebooting. No effect. Booting into Windows. It works properly, so probably not a hardware issue. All of alsamixer. My only controls are this: "Master" Volume bar & mutable, unmuted. Controls volume. "PCM" Volume bar only. 100%. "S/PDIF" Mutable only, currently muted, has no effect. "S/PDIF" Default PCM", Mutable only, currently unmuted, has no effect. Killing PulseAudio. No effect. (It also won't stay dead! Something appears to be restarting it, and I can't tell what, but it is annoying as fuck.) alsactl init 0, no effect. sudo rm -f /var/lib/alsa/asound.state, no effect. General system info: Ubuntu 10.04 LTS Toshiba Satellite T135D-S1324 lspci says I have: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

• hyper-v cluster behavior when losing network connectivity

  - by ChristopheD

  Setup: (rather new) Hyper-V R2 cluster with 2 nodes (in failover configuration). Fysical host OS: Windows Server 2008. About eight VM's (mixed: Windows Server 2008 and Linux) Yesterday we had a power outage of about 15 minutes. Our blades are on UPS so the fysical host machines (Windows Server 2008) never went down. Our main switches are not on UPS (yet) and we saw the behaviour similar to the following (as distilled from the event logs). The nodes in the cluster lost means of communication (because the external switches went down). The cluster wants to bring down one (the first) of the nodes (to start failover?). The previous step impacts clustered storage where the virtual machine VHD's are located. All VM's got brutally terminated and were found in a failed state in the failover manager in the host OS'es. The Linux VM's were kernel panicking and looked like they had their disk ripped out. This whole setup is rather new to us, so we are still learning about this. The question: We are putting switches on UPS soon but were wondering if the above is expected behavior (seems rather fragile) or if there are obvious improvements configuration-wise to handle such scenario's ? I can upload an evtx file concerning what exactly was going on in case that's necessary.

• Outlook 2007 panes keep moving when changing resolution

  - by SilverbackNet

  This problem is really bugging one of our users ever since he got a larger monitor. Now that the monitor has a different resolution than his laptop, every time he unplugs it to go home, the three Outlook panes get all jumbled up. The navigation is huge, the list is shoved over, and the reading pane is almost smushed out of existence, the the opposite when he comes back in and the reading pane fills the screen. He's sick of adjusting it every day. He always runs it maximized, for maximum reading area. Keeping the application within a 1024x768 window wouldn't really be an option for him. Is there any way built into Outlook to automatically adjust pane sizes when the resolution changes? If not, is there a third-party app that can help, or a way to script the changes into the registry somehow? (I can do running the script whenever the screen state changes.) If this is fixed in 2010 I might be able to convince the other admin that this is a good enough reason to allow it (which will require a new beta version of our archiving software).

• Why is this iptables rule that does port forwarding not working?

  - by videoguy

  I have a server bound to localhost:7060. It is using ipv6 socket instead of ipv4. Below is netstat outout. # netstat -an Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 10.200.32.98:1720 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:4122 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:4123 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:4123 127.0.0.1:43051 ESTABLISHED tcp 0 0 10.200.32.98:5555 10.200.32.44:53162 ESTABLISHED tcp6 0 0 :::5060 :::* LISTEN tcp6 0 0 ::ffff:127.0.0.1:7060 :::* LISTEN tcp6 0 0 :::23 :::* LISTEN tcp6 0 0 ::ffff:10.200.32.98:23 ::ffff:10.200.32.142:43505 ESTABLISHED tcp6 0 0 ::ffff:127.0.0.1:43051 ::ffff:127.0.0.1:4123 ESTABLISHED tcp6 0 0 ::ffff:10.200.32.98:23 ::ffff:10.200.32.44:53195 ESTABLISHED udp6 0 0 :::5060 :::* CLOSE # I want to setup a port forwarding rule that accepts connections on port 24 (on all interfaces loopback as well as eth0) and forward the data to localhost:7060. This is how I am setting up the iptables rule: iptables -t nat -A PREROUTING -p tcp --dport 24 -j DNAT --to 127.0.0.1:7060** It is not working. When I telnet from different box, I see the following $telnet 10.200.32.98 24 Trying 10.200.32.98... If I change the server to bind to *:7060 and set the following rule, it seems to work fine. iptables -t nat -A PREROUTING -p tcp --dport 24 -j REDIRECT --to-port 7060 But that will make my server available on WAN interface which I don't like. I feel it had something to do with ipv6 socket (tcp6 line in netstat output). This whole thing is done on an Android device with custom built Android platform image. How do I get this working?

• Cannot get at data in my NAS

  - by Ben

  I've got a bit of an issue that I'm hoping you can help me with. I have an Iomega ix4 as my NAS. This runs Linux and each drive in the box has 2 partitions: one for the OS and RAID info, and the second for the actual data. I had it configured as RAID5. Recently one of the drives failed. At this point all of the data was available, it was just reporting a failed drive. I had a drive of the same capacity (although not the exact same spec) which I swapped in place of the failed drive. It recognised it, and started to rebuild the data protection. So far so good ... or so I thought. The next day, after data protection had finished reconstructing, the NAS was telling me that 4 new drives had been added, and wanted confirmation to overwrite the data. Obviously I declined to do this. I swapped the failed drive back in again, in the hope that it would return to its previous state of the data being accessible, but one failed disk. However it didn't - it still tells me that the NAS has 4 new drives in it. I am hopeful that the actual data is untouched, so what I need to do is get it to rebuild the RAID without touching the data on the disks. I have ssh access, and have run stuff like mdadm --examine to see what I can find. The mdadm.conf file has no entry in the "definitions of existing MD arrays" section. I have not run any actual rebuilding commands as yet, because this is entering an area which I am out of my depth in. Please can someone advise the best way of getting my data? Thanks.

• 3dmark score abnormal

  - by Sean

  I just bought a new laptop. It is core i7 3610QM.(Ivy bridge, 4 core plus hyperthreading), 8G ram, nvidia GT 610M 2GB. The OS is Win7 64bit. I ran 3dmark 11, but the score is frustrating. For 1280*720, the score is P730. It is too low right? I searched online, the score should at least above 1000. Am I right? I never use this software before. I know nvidia has optimus, so I made the laptop in high performance state and white-listed the 3dmark program. But there is no help. I am guessing 3dmark is using i7's graphic module. It cannot transform to nvidia. In the running detail of 3dmark, the graphic card cannot be identified(The row remain blank). Can anybody tell me is this the normal case? If not, can I use some other software to test if my nvidia card is working fine? If this nvidia card cannot work, I will return the new laptop asap. Thanks.

• Input/output error reading USB backup drive on CentOS 6.4

  - by Kev

  I'm suddenly seeing some strange behaviour on our USB backup drive that doesn't make sense to me: (2013-10-21 14:58:23 [root@newdc /]$ cd /mnt/backup/ (2013-10-21 14:59:03 [root@newdc backup]$ ls -la ls: reading directory .: Input/output error total 0 (2013-10-21 14:59:05 [root@newdc backup]$ df -h /mnt/backup Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 843G 28G 97% /mnt/backup How is it possible for the OS to know how much is in use, but I can't ls any of it as root? Or more to the point, what problem does this indicate? /var/log/messages said this: Oct 21 14:57:54 g5 kernel: EXT4-fs error (device sda1): ext4_journal_start_sb: Detected aborted journal Oct 21 14:57:54 g5 kernel: EXT4-fs (sda1): Remounting filesystem read-only But...read-only is something different than 'throw an io error'... After unmounting to try fsck on it, I had someone on-site look at it, and the drive was not spun up, and had a slow-flashing light, which I believe means it was in a power-suspend mode. So I had them unplug and replug the USB cable, and now (before remounting) it says: fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) /dev/sda1: clean, 2805106/61046784 files, 181934167/244182016 blocks I then mount it and now ls works and df reports: Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 680G 191G 79% /mnt/backup What would cause it to go into such a state without being asked to? Why all the weird behaviour, and now it appears to not be corrupt?

• Windows Search not searching in files

  - by Cylindric

  I am trying to get Windows Search to work on my Windows Server 2008 SP2 fileserver, so I can search in files for content. I have added the Windows Search Service role to the server, and using the right-click properties in Explorer set some folders to "Index this location". The problem is that neither on the server or remotely can I search in the files. I seem to get some inconsistencies in the GUIs, for example the "Indexing Options" panel shows me just 6 locations indexed, but if I click "Modify" I see nearly everything ticked. For example, the "SeachTest" folder under "infrastructure" has the "index this location" option ticked, but the "Projects" folder does not. I assume this is why some are grey and some not, but they are all ticked. T The "SearchTest" folder contains some files that have nothing but the text PurpleOrange in it, so I should be able to find those. So, to summarise: Which locations are indexed? The ones in the "Index these locations" list, the ones ticked, or the ones not greyed-out in the list? How do I get to the state where I can click in the search box and type PurpleOrange and see the files?
