• How to show what will be updated next pull?

  - by ???

  In SVN, doing svn update will show a list of full paths with a status prefix: $ svn update M foo/bar U another/bar Revision 123 I need to get this update list to do some post-process work. After I have transferred the SVN repository to Git, I can't find a way to get the update list: $ git pull Updating 9607ca4..61584c3 Fast-forward .gitignore | 1 + uni/.gitignore | 1 + uni/package/cooldeb/.gitignore | 1 + uni/package/cooldeb/Makefile.am | 2 +- uni/package/cooldeb/VERSION.av | 10 +- uni/package/cooldeb/cideb | 10 +- uni/package/cooldeb/cooldeb.sh | 2 +- uni/package/cooldeb/newdeb | 53 +++- ...update-and-deb-redist => update-and-deb-redist} | 5 +- uni/utils/2tree/{list2tree => 2tree} | 12 +- uni/utils/2tree/ChangeLog | 4 +- uni/utils/2tree/Makefile.am | 2 +- I can translate the Git pull status list to SVN's format: M .gitignore M uni/.gitignore M uni/package/cooldeb/.gitignore M uni/package/cooldeb/Makefile.am M uni/package/cooldeb/VERSION.av M uni/package/cooldeb/cideb M uni/package/cooldeb/cooldeb.sh M uni/package/cooldeb/newdeb M ...update-and-deb-redist => update-and-deb-redist} M uni/utils/2tree/{list2tree => 2tree} M uni/utils/2tree/ChangeLog M uni/utils/2tree/Makefile.am However, some entries having long path names are abbreviated, such as uni/package/cooldeb/update-and-deb-redist is abbreviated to ...update-and-deb-redist. I deem I can do with Git directly, maybe I can configure git pull's output in special format. Any idea?

• PCI configuration method error (Linux Kernel)

  - by user326580

  (I'm not sure if here is the best place for that question, so I will be pleased if anyone suggests me a more proper forum for that.) I'm trying to install Ubuntu 12.04.4 in a netbook (from an usb), but the kernel stops very early in initialization process. After two days of research, I've found that it boots with the parameter pci=conf2 but not with the default conf1 method. Nevertheless, after kernel boot, it seems that Ubuntu can't find usb devices and I'm not be able to install it. Trying with Debian, its a graphic installer and I found that the mouse isn't working neither.I think pci devices are not working. I tried about 50% of kernel pci boot options in the kernel-parameters file (in conjunction with the implicit default conf1) without luck. Any suggestions? PS: The problem is the same with kernel 2.6 or 3. (In Spanish) No estoy seguro si éste es el mejor lugar para esta pregunta, por lo cual estaré encantado si alguno me sugiere un mejor lugar para ella. Estoy intentando instalar Ubuntu 12.04.4 en una netbook (desde un usb), pero el kernel se detiene muy temprano en la inicialización. Después de dos días de investigar, encontré que arranca con el parámetro pci=conf2 pero no con método default conf1. Sin embargo después de que el kernel arranca, parece que Ubuntu no logra encontrar los dispositivos usb y no puedo instalar el sistema. Intentando con Debian y su instalador gráfico, encontré que el ratón tampoco funcionaba, así que pienso que los dispositivos pci no están funcionando. Intenté con aproximadamente el 50% de las opciones de arranque del kernel para pci (en conjunción con el método implícito conf1) sin suerte. Alguna idea? PS: El problema es el mismo con el kernel 2.6 o 3.

• I think my laptop just died

  - by Joel Coehoorn

  I have a Dell 1330M that as of about 15 minutes ago will no longer POST. What happened was I was working, stepped away for a moment, and when I came back it was turned off. I thought that was odd, but turned it on and things seemed fine. About 1/2 hour later it crashed and restarted, but came up fine again. It did this once more. At this point I was starting to get worried, but I hadn't had any problems with the laptop before and every crash was after doing some work in a virtual machine that I don't often use, so I at put the blame there. It didn't feel like it was overheating anywhere and there's no ozone smell of overheated electronics. Then it crashed a final time and now when I turn it on all I see is a bright screen with a bunch of vertical lines (noise). I've tried removing the memory sticks one at a time, but I get the same result with either memory stick in either slot. With no memory at all it stops earlier in the POST process and the screen is completely blank (black, no backlight). As I type this, I hear a double beep from the system about once every 10 minutes. I'm pretty sure the hard drive is fine because it fails during post, before anything off the drive is needed. The power supply seems good because the screen is nice and bright. It's not the RAM because swapping that around made no difference. The leaves motherboard (which I doubt and can replace) and CPU (which just might be changable). Any ideas? Is there any hope for this laptop? I'm rather fond of it and I'd have a hard time replacing it with anything near as nice.

• Missing Boot Manager in Vista

  - by Selase

  I am in really deep trouble here and would need advice. A message just pop up on my screen and I had to restart my laptop. Upon restarting the Boot Manager got corrupted. I am running Windows Vista 32 bit by the way. I got onto Google with a friend's PC and found two basic ways of fixing it. The first one that requires Windows to automatically fix it using Startup repair ends up with the error message: Startup REpair cannot repair this computer automatically The second option that requires me to rebuild the BCD scans my system and finds the operating system on drive D:\Windows which I believe should be C:. If I hit Y(yes) for the rebuild process to take place I get the message The required system device cannot be found I then try the second option which requires me to recreate the BCD Store. It ends up with an error message that says: The store export operation has failed. The requested system device cannot be found Proceeding from there is meaningless since the system device cannot be found. I somehow believe the device cannot be found because it's identifying the Windows installation on D: instead of C: but how to change that I have no idea. I don't know how it happens to identify an operating system on D: when there's none there. How do I go about fixing the Boot Manager? I have very important files on my system and can't afford to reinstall Windows. I really need to fix this.

• VLC Crash when playing MKV files in Windows 7

  I'm not sure if the mkv file is corrupted, but when it is opened with VLC player, VLC loads up and displays nothing. Can't even close VLC after that. And also, VLC is running with 50% of the CPU.

• Relevance and Necessity of SNMP

  - by Adam Tannon

  Edit: I am in the process of designing a Java-based monitoring tool that will send back periodic "health checks" of a Java app deployed to a cluster of GlassFish servers. I am trying to figure out the best protocol for this monitoring tool to send information back to the monitoring server on. After an initial research effort on my part, it seems like SNMP is just a protocol for monitor-type applications to communicate the "health status" of something (a part of a network, a server, a cluster, an application, etc.) to the rest of the network. If the above is incorrect, please correct me!!! Assuming the generalization is more or less accurate, my next question is: why is this a protocol!?!? In the age of REST/SOAP/TCP protocols, why is there the need for a standardized protocol that only fits one type of application (monitoring)? In other words, if I'm a developer assigned to building a new monitoring tool that periodically polls a server and reports on its CPU and available memory, what advantages does SNMP give me over just POSTing to a RESTful API via plain 'ole HTTP? I'm sure I'm missing something here - I just need someone to help connect the dots! Thanks in advance!

• Packet flooding while configuring a Debian L2TP/IPSec client?

  - by Joseph B.

  I'm currently at my wits end trying to configure an L2TP over IPSec VPN connection on my Debian using openswan and xl2tp box connecting to a server of unknown configuration. I've managed to successfully establish the connection and everything appears to be working well until I attempt to set the VPN connection as my default route, at which point I see a massive flood of packets simultaneously being transmitted (on the tune of ~1.5 GB in about 2min) until the server drops my connection. Prior to this network traffic on all my interfaces is minimal. According to iftop the majority of this traffic appears to be coming out of port 12, although I can't seem to figure out how to finger a specific process. If I instead just route traffic destined for 74.0.0.0/8 through it I'm able to access Google's servers through the VPN without issue. My xl2tp.conf file is: [lac vpn-nl] lns = example.vpn.com name = myusername pppoptfile = /etc/ppp/options.l2tpd.client My options.l2tpd.client file is: ipcp-accept-local ipcp-accept-remote refuse-eap require-mschap-v2 noccp noauth idle 1800 mtu 1410 mru 1410 usepeerdns lock name myusername password mypassword connect-delay 5000 And my routing table looks like: Destination Gateway Genmask Flags Metric Ref Use Iface 10.5.2.1 * 255.255.255.255 UH 0 0 0 ppp0 10.0.50.0 * 255.255.255.0 U 0 0 0 eth0 10.50.0.0 * 255.255.0.0 U 0 0 0 eth0 10.0.0.0 * 255.255.0.0 U 0 0 0 eth0 192.168.0.0 * 255.255.0.0 U 0 0 0 eth0 loopback * 255.0.0.0 U 0 0 0 lo default * 0.0.0.0 U 0 0 0 ppp0 I'm seeing absolutely nothing in auth.log and syslog during this time and can't seem to find any other log files it might be writing to. Any suggestions would be appreciated!

• linux shutdown hang with wifi cifs mounts

  - by Sirex

  Since fedora 15 (and now with 16) it seems that wireless clients take a long while to shutdown when they have network filesystems mounted at shutdown time. I've pushed out a cifs mount via puppet, and all clients have it, including those on wireless. If say a laptop is on a wired connection it shuts down just fine, but if its on the wifi at the time (and no wired connection) it'll hang at the fedora f logo. I'm not sure if its indefinite or just a really long while, but ill give it a test when i shut this machine down in a second. Needless to say its pretty annoying, so is there a way of causing the machine to shutdown even if network connectivity has been lost at unmount time, -- or an official way to reorder events so the wireless card is kept up until after the unmount happens during the shut down process (short of writing a custom script for shutdowns which is a bit of a kludge) ? It does this on multiple machines, and all started doing it when we went from fedora 14 to 15. It was such an obvious issue i'd kind of assumed someone must have reported it or there was an easy fix, but i've not discovered anything yet. Additional info: I can confirm that manually unmounting the mounts then shutting down (sudo shutdown or the xfce shutdown button) will shutdown just fine, it only hangs if the mounts are still mounted The puppet config that sets the mount looks like this (now with the _netdev entry that is indeed pushed to clients successfully, but makes no difference): file { "/mnt/share": ensure = directory,} mount { "/mnt/share": atboot = true, ensure = mounted, remounts = false, fstype = cifs, device = "//srv/share", options = "user,gid=shareusers,uid=${user},file_mode=0700,dir_mode=0700,credentials=/root/.smbcreds,_netdev", require = [ File["/mnt/share"], Group["shareusers"] ], } }

• Windows 7 breaks even in safe mode

  - by delenda

  Hi, I have a Dell XPS M1730 with Windows 7 installed. I noticed last night that after a few hours of use, the fans kicked into full and I couldn't do anything without it taking forever. Minimising windows, opening device manager or even opening process explorer took minutes and a game install I had just started took nearly 4 hours to complete. When procexp finally loaded, the refresh was so slow that it was mostly useless. From what I could gather, it was reporting 60% idle processes with procexp using nearly 40%. There were no hardware interrupts listed. When I rebooted, the problem went away for about 10 minutes and then the same thing happened. The issue persists in safe mode and even after I removed the graphics drivers, which have been an issue in the past, it still happens. Icons flash quite quickly on the desktop periodically and screen refresh is painfully slow. When booting now, the fans kick in to full as soon as the windows logon box comes up and it's taking 10 minutes to bring the desktop up. Chkdsk reports nothing and the raid check says that everything is fine. I'm thinking hardware failure, probably HDD but wanted some other opinions. I'm planning to try a linux live cd to see if it works without using the hard disks. If anyone has any input, it would be greatly appreciated. Delenda

• Hibernation fails; The system cannot find the file specified

  - by GMMan

  Recently I installed Ubuntu 12.04.1 LTS on my Lenovo Y480. Hibernation was working properly after the Ubuntu install, but I was making sure all of the operating systems on my system worked, including OneKey Recovery (recovery partition). It is of note that I installed Windows 7 from scratch with a disk image I downloaded off of my university's DreamSpark program, and further to that I had to image the partition with Paragon Backup & Recovery, repartition to convert the Windows partition to extended, install Ubuntu, and then restore the image. During that process I also used the Windows disc to edit the BCD as to reuse the existing entry for the restored partition. I also used the automated "repair your computer" option. With verification, I noticed that the "repair your computer" option actually wrote to the wrong BCD (the recovery partition), and I mounted the partition and restored the original BCD (from a copy I made earlier), and rebooted. At this point my GRUB broke, and I was able to restore it. At this point hibernation broke. I tried powercfg /h off and powercfg /h on, rebooted, and nothing. Also tried increasing the hibernation file size as directed on this post, but it still doesn't work. Executing shutdown /h yields The system cannot find the file specified.(2). What file? It seems that mounting the system partition sometimes works, but I don't want to keep it mounted in case it gets written to accidentally. How do I permanently fix this?

• Which scripting language to use to asynchronously ssh into equipment, run several commands, parse the output, and save to a file on my computer?

  - by Fujin

  There are several points I'd like to stress in my question. I'd like to login by asynchronously ssh'ing into our infrastructure equipment. Meaning, I do not want to connect to only one device, do all the tasks I need, disconnect, then connect to the next device. I want to connect to several devices at once in order to make the process as fast as possible. By equipment I mean 'infrastructure equipment' and not servers. I say this because I will not have the luxury of saving files to the device then transferring them to myself with scp or another method. The output of the scripts that are run will have to be saved directly to my computer. The output of the commands that are run will need to be cleaned up and parsed. Also I want the outputs of each device to be combined into one nice and neat file, not a separate file for each device. This will all be done from a linux box, using ssh, into devices that all use linux'ish proprietary OSes. My guess is the answer to my question will either be a Bash, Perl, or Python script but I figured it wouldn't hurt to ask and to hear the reasons why one way is better than another. Thanks everyone. EXTRA CREDIT: With you answer, include links to resources that will help create the script I described in the language that you suggested.

• troubleshooting really slow login on a (linux) machine

  - by Peeter Joot

  Within the last couple of weeks, any attempt to login to a specific linux server has gotten really slow. Once I've logged in, things appear to run without significant delay, but some other login like activities (like starting a new screen session) are slow. The machine's been rebooted a couple of times recently and that hasn't helped. , and it doesn't appear to be $PATH search (where $PATH can sometimes include bad NFS mounts), which I've seen historically in our environment. I've also tried completely removing my .profile/.bash*/... type of init files to rule out anything bad there. I also see slow login for at least one other userid on the system. One thing I've noticed is the following message when trying to exit from a screen terminal: Utmp slot not found -> not removed and am wondering if this is related (having a vague recollection that Utmp has something to do with login). Any idea what that message means, or how to fix it, and if it would be related? Failing that, what sort of problem determination tools are available to investigate what is slowing down this login process?

• 2012 R2 services will not start after promotion to Domain Controller

  - by Cybersylum

  Having a peculiar issue promoting a Windows 2012 R2 server in a domain at 2003 domain/forest functional level. Built a new 2012 R2 server, added the following software (labtech, appassure, eset A/V, & Teamviewer). It activated and appeared to be working fine. I added the Active Directory Domain Services role, and completed the configuration (Domain/Forest Prep, and DC promotion). All appeared to go well. I rebooted the server, and that's where the peculiar stuff began. I noticed the server indicated it needed activated again; but would not accept the key. I verified the key was good. That's when I noticed the Software Protection service (as well as many other core services - Base Filtering engine, DHCP client, firewall, etc) would not start. The error message for all of them was "Access Denied". I called MS, and they wanted to troubleshoot at a service level. Their fix was to use procmon and identify the resource that needed permissions (registry key, file or folder) and add "everyone" with full control). That got the services to start; but the problem re-appeared after a reboot. Thinking the issue might have been with the anti-virus package during the promotion process, I rebuilt the DCs from scratch and removed the metadata from AD (as I could not demote the machines "rpc server unavailble"). I tried to promote the newly built machines again. The only changes to the brand new machines being critical updates. Again the promotion appeared to work fine; but upon reboot (and a long wait to allow replication to occur) similar problems began to re-appear. I have verified that the schema updates are correct (schema version is 69 - for Windows 2012 R2). I am not finding much about this issue through my own searches, so I thought I would post this to see if anyone else has seen anything similar...

• Problem with setting up RAID 5 on FreeNAS

  - by Benjy23

  I've been running FreeNAS for a while now. Hardware is 1.8 GHz Celeron, RAM 1 GB. SATA card is Via - I am not sure about the model. It's 2 ports and I have 6 x 1.5 TB hard drives. All ran OK while running on 1.5 TB, no RAID. I'm now trying to create a RAID 5 with my 6 hard drives. Software RAID. Is it normal for it to take roughly up to 2 weeks just to build the RAID? Sorry, I'm very new to implementing RAID and googling doesn't tell much other than it takes a long time. Also the RAID building process seems to fail many times. Going to degraded. I suspect it's because 4 of my hard drives are connected to my motherboard and the other 2 are connected to my SATA card. What's your take? I'm considering 2 options now. Either get a 8 port SATA card and attach all the hard drives to it. Or get a RAID controller 8 portcard which is probably going to be more pricey. Also how do you access hardware RAID through FreeNAS? I like how FreeNAS emails you should your harddrive fails. Can this be done as well with hardware RAID?

• How do I set up Grub properly to quad-boot Windows, Mac OS X, Linux, and FreeBSD?

  - by Joe

  Grub has gone completely insane on me. My quad-boot system was working great up until I upgraded Ubuntu to 12.04. Since Ubuntu overwrote the Grub stuff I had to repair it with my Mac OS X and FreeBSD entries. After this, trying to boot Mac OS X gave me the error "couldn't open file" and FreeBSD gave the error "no such partition". Windows and Ubuntu worked fine. So I tried repairing again because I figured something must've gone wrong in the install process. Then only Ubuntu would boot. Trying to boot Windows would give me the error "no argument specified". I tried repairing Grub once again, since I seemed to be getting different results each time. This time, Ubuntu no longer appeared in the Grub menu, and the errors for the other OSes were the same. So I booted into the Ubuntu 12.04 live CD and ran Boot-Repair with recommended settings. Now Grub is completely skipped and Windows boots up. I have absolutely no idea what is going on or why I get different results every time I reinstall Grub. Here is how my partitions are set up: sda1 - Storage drive, sdb1 - Windows, sdb2 - Mac OS X, sdb3 - FreeBSD, sdb4 - Extended, sdb5 - Ubuntu, sdb6 - Shared storage, sdb7 - Shared Storage, Here's my grub.cfg file: grub.cfg

• Simulate a DFS share for a user not on domain with a folder in path

  - by user223655

  I have a consultant whose computer is not on the domain and needs to access various network resources. Unfortunately while adding a computer to the domain is a difficult bureaucratic process (and would disallow much of his development software from even running given the domain restrictions), we can allow him to have credentials to access network resources. As such, he accesses various network resources via NET USE etc. without using DFS. There is one piece of software which requires him to have the same hardcoded path as other domain users but that path is a DFS path which he can't map (i.e., the software checks the path at runtime and will only run if it matches the registered path and will reject it in the context of using a DFS versus conventional machine path) I was wondering if there's some method to simulate the DFS path without actually using DFS. e.g., the path the software needs to see is "\ABC\DFS\software\app.exe" whereas the non DFS path is "\DEF\Software\app.exe" while I could make his hosts file point DEF to ABC, I'm not sure if I can somehow make it point there with the DFS "folder" as well are there any methods for this short of making changes to the AD to allow him to use DFS or add him to the domain (both of which are politically/technically challenging sadly)? Thanks guys

• Heavy write to Galera cluster - table locked, cluster practically unusable

  - by Joe

  I set up Galera Cluster on 3 nodes. It works perfectly for reading data. I have done simple application to make some test on the cluster. Unfortunately I have to say that the Cluster fails totally when I try to do some writing. Maybe it can be configured differently or I do sth wrong? I have a simple stored procedure: CREATE PROCEDURE testproc(IN p_idWorker INTEGER) BEGIN DECLARE t_id INT DEFAULT -1; DECLARE t_counter INT ; UPDATE test SET idWorker = p_idWorker WHERE counter = 0 AND idWorker IS NULL limit 1; SELECT id FROM test WHERE idWorker = p_idWorker LIMIT 1 INTO t_id; SELECT ABS(MAX(counter)/MIN(counter)) FROM TEST INTO t_counter; SELECT COUNT(*) FROM test WHERE counter = 0 INTO t_counter; IF t_id >= 0 THEN UPDATE test SET counter = counter + 1 WHERE id = t_id; UPDATE test SET idWorker = NULL WHERE id = t_id; SELECT t_counter AS res; ELSE SELECT 'end' AS res; END IF; END $$ Now my simple C# application creates for example 3 MySQL clients in separate threads and each one executes the procedure every 100ms until there is no record where column 'counter' = 0. Unfortunately - after about 10 seconds sth is going bad. On servers there is process 'query_end' that never ends. After that - you cannot make update on the test table, MySQL returns: ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting transaction . You cant even restart mysql. What you can do is to restart server, sometimes whole cluster. Is Galera Cluster so unreliable when you do massive concucurrent writing/updates? Hard to believe.

• Could replacing an old hard drive's circuit board make it work again?

  - by oscilatingcretin

  I have a 12-year-old, 10gb Maxtor drive that died on me around 7 years ago, but I have not had the heart to throw it away. When the computer powers on, it whirrs silently as it tries to spin up and then it stops. So, a few years ago, I sent it off for professional data recovery. They were able to retrieve quite a bit from it, but I know there's a bunch more there. It only cost $700, so I just chalked up the lackluster recovery effort to "you get what you pay for" considering that most companies will charge you several thousands of dollars for this kind of data recovery. When they sent the drive back, I couldn't help but plug it back in just to see if maybe they unjammed something in the process of disassembling/reassembling the drive. To my surprise, the drive had a much healthier spin-up sound and actually stayed spinning for several minutes before winding down to a halt. Windows is even able to detect and interact with the drive, but I get I/O errors after so many minutes of waiting for it to mount. Before I start doing stupid stuff with it like dropping it on the ground, freezing it, crapping on it, etc, I decided to buy the exact same model off Ebay so that I could swap the circuit boards as a last-ditch effort. While it's en route, I thought I'd come here to ask if this is even a worthwhile effort and, if even remotely so, what should I know before ripping off the old board and slapping on the new?

• Copy Database Wizard fails on creation of view into another not-yet-copied database

  - by user22037

  Update - I found that doing a manual detach/reattach using MSDN article "How to: Move a Database Using Detach and Attach (Transact-SQL)" got around this issue. I'll just be creating a script to dettach and reattach but do the file copies manually. Any info on how to overcome the problems with the wizard would be helpful in the future. I am in the process of moving around 20 databases from our current server to a new one. When performing the copies however I have found that some databases can not copy if they have views into other databases that have not yet been copied to the target system. The log file generated says "failed with the following error: "Invalid object name" in reference to the database in the view. If I first copy just the database referenced in the view and then in a separate step copy the database over containing the view it is successful. However some other database have views into each other so can't just adjust the order in which the copy occurs. Is there any way to ignore this error and just allow everything to copy?

• Network driver for Hyper-V restore from Windows Home Server

  - by Philipp Schmid

  I have backed up Windows Server 2008 running virtualized on Hyper-V to a Windows Home Server 2008 SP1 (I know I should have backed up the VHD instead). Now I need to restore the contents of the VM from WHS. I have created a restore CD ISO and used it to create a new VM. It all works as advertised up to the point where the restore process wants to load the network drivers (it only finds 4 disk drivers on the restore CD. but no network drivers). So I created a virtual floppy and copied the contents of 'Home Server Drivers for Restore onto it. But no luck! I have tried moving the 4 subdirectories into the root of the floppy, but that didn't work either. Finally, I started another instance of the WS 2008 to identify the network driver that the virtualized instance is using (%WINDOWS%\system32\drivers\netvsc60.sys) and copied that file onto the virtual floppy, without success. Does anyone have any suggestions on how to get networking working on a Hyper-V instance running off the Windows Home Server Restore CD? UPDATE: As suggested by delenda, I have added a legacy network adapter to my VM, and indeed I now get a network driver listed! However, the WHS it still not found, even after entering the home server name manually. PHS

• WINDOWS: Your computer hangs. You can windows + R (run dialog) but performance is so halted taskMGR

  - by John Sullivan

  The question is, what process are available to try to recover from total system instability before pulling the plug when we can do nothing but programs or batches in the path from the run dialog (windows + r key), and performance is so dead that taskMGR / procEXP / other programs with visual guis are not usable? I am not a windows expert, but ideally someone out there has written a program that does more or less stuff like this: Immediately set (or perhaps I can set from the run prompt) its priority to extremely high, evaluate performance bottlenecks. E.g. is CPU 100%? If so identify offending program(s) or problems. Attempt / log fixes, then provide crude feedback asking the user if his performance has stabilized enough to abort, wait a few seconds, if no feedback continue, etc. etc. Eventually try to do any "system cleanup" if the program decides it cannot recover and perhaps finally provide a series of beeps to the user, or what have you, to say "OK, I give up, time to pull the plug". Ideally create a log, when able. These kinds of horrible hangs are a situation where surely trying something, anything, is better than nothing -- as long as that something is intelligent -- when the alternative is ripping out the power coord. Again, I am not a windows expert, so perhaps there is a much more elegant "hands on" approach I am not aware of.

• Windows 8 Windows Store (Metro/ModernUI) applications not working (just show 'busy' animation or white screen)

  - by davidm_uk

  I have a Dell XPS 15 which shipped with Windows 7 x64, which I recently upgraded to Windows 8. The process went surprisingly smoothly (given that this was an upgrade, not a complete re-install), and the system generally seems very stable. However, today I noticed that several of the Windows Store apps don't work: they all behave in the same way, launching but then showing a spinning 'wait' animation indefinitely. This is affecting the standard Microsoft Mail, Store, Weather, News, Travel, Finance, Sport, Games and Music apps. The Bing app just shows a Bing logo on a coloured background (but no wait animation). The Calendar, Photos and SkyDrive apps open but then show a white screen. The Maps and Camera apps work without problems. The live tiles on the Start screen are updating correctly, for example the Mail app's tile shows a summary of new mail despite the Mail app's problems. All of these applications were working correctly a few days ago. I'm sure I've used several without problems since the last Windows update occurred on 7th November. Any suggestions on what might have happened and/or how to fix it would be very welcome. I don't need these Windows Store applications, but the fact that they're not working is irritating me.

• Why is my rsync so slow compared to pure cp or even scp?

  - by nfm

  I'm transfering the files from Linux to Windows 7 via a mounted share (the share is mounted from Windows on Linux).. I'm copying lots of data (i.e. nearly a TB) from the old to the new machine within my LAN. I'm unfortunate enough already that I only have 100MBit. Naturally I blindly used rsync but already wondered after a day why it feels so slow. Enabling the progress meter showed my a transfer rate of about 2MBit/s . So I took a reasonable big file (800MB) and tracked the transfer timing: cp : 05:33 scp (*): 06:33 rsync : 21:51 *) scp via localhost to the same Linux machine directly onto the share; completely useless but provided a progress meter The tests were as simple as (cp|scp|rsync) <source> <destination> No special arguments except host/port for scp. I even tried the -W switch for rsync but cancelled after ten minutes. rsync is 3.0.3 running on Lenny. To be able to interrupt the copy process anytime and resume lead me to rsync, but now I think I seriously need to reconsider this requirement. How's such a big difference possible?
