  • usb_modeswitch not switching

    - by deniz
    After I upgraded from kernel 2.6.18 to 3.5.3 modeswitch started not to work for me. Although lsusb shows my usb modem, usb_modeswitch does not switch it. My system information is like below. I ran lsusb, dmesg, usb-devices and usb_modeswitch their output is like below. usb_modeswitch instead of switching my modem it says "No devices in default mode found. Nothing to do. Bye.". Can you offer a solution?

  • Do RAID controllers commonly have SATA drive brand compatibility issues?

    - by Jeff Atwood
    We've struggled with the RAID controller in our database server, a Lenovo ThinkServer RD120. It is a rebranded Adaptec that Lenovo / IBM dubs the ServeRAID 8k. We have patched this ServeRAID 8k up to the very latest and greatest: RAID bios version RAID backplane bios version Windows Server 2008 driver This RAID controller has had multiple critical BIOS updates even in the short 4 month time we've owned it, and the change history is just.. well, scary. We've tried both write-back and write-through strategies on the logical RAID drives. We still get intermittent I/O errors under heavy disk activity. They are not common, but serious when they happen, as they cause SQL Server 2008 I/O timeouts and sometimes failure of SQL connection pools. We were at the end of our rope troubleshooting this problem. Short of hardcore stuff like replacing the entire server, or replacing the RAID hardware, we were getting desperate. When I first got the server, I had a problem where drive bay #6 wasn't recognized. Switching out hard drives to a different brand, strangely, fixed this -- and updating the RAID BIOS (for the first of many times) fixed it permanently, so I was able to use the original "incompatible" drive in bay 6. On a hunch, I began to assume that the Western Digital SATA hard drives I chose were somehow incompatible with the ServeRAID 8k controller. Buying 6 new hard drives was one of the cheaper options on the table, so I went for 6 Hitachi (aka IBM, aka Lenovo) hard drives under the theory that an IBM/Lenovo RAID controller is more likely to work with the drives it's typically sold with. Looks like that hunch paid off -- we've been through three of our heaviest load days (mon,tue,wed) without a single I/O error of any kind. Prior to this we regularly had at least one I/O "event" in this time frame. It sure looks like switching brands of hard drive has fixed our intermittent RAID I/O problems! While I understand that IBM/Lenovo probably tests their RAID controller exclusively with their own brand of hard drives, I'm disturbed that a RAID controller would have such subtle I/O problems with particular brands of hard drives. So my question is, is this sort of SATA drive incompatibility common with RAID controllers? Are there some brands of drives that work better than others, or are "validated" against particular RAID controller? I had sort of assumed that all commodity SATA hard drives were alike and would work reasonably well in any given RAID controller (of sufficient quality).

  • USB Flash not recognised by Windows and BIOS, but works fine in Linux

    - by bbalegere
    I have a Transcend JetFLash 2GB USB Drive.It was working fine and I had been using it occasionally. All of sudden it stopped working in all versions of Windows . The USB Drive is also not recognised by the BIOS.It does not show in the list of bootable devices.(It used show up in the list earlier) However the USB Drive works fine in my Linux Mint 11 OS. Running dmesg gives this [ 941.812192] usb 1-2: new high speed USB device using ehci_hcd and address 4 [ 941.936178] usb 1-2: device descriptor read/64, error -71 [ 942.164188] usb 1-2: device descriptor read/64, error -71 [ 942.380189] usb 1-2: new high speed USB device using ehci_hcd and address 5 [ 942.504138] usb 1-2: device descriptor read/64, error -71 [ 942.732179] usb 1-2: device descriptor read/64, error -71 [ 942.948154] usb 1-2: new high speed USB device using ehci_hcd and address 6 [ 943.364134] usb 1-2: device not accepting address 6, error -71 [ 943.476172] usb 1-2: new high speed USB device using ehci_hcd and address 7 [ 943.892140] usb 1-2: device not accepting address 7, error -71 [ 943.892191] hub 1-0:1.0: unable to enumerate USB device on port 2 [ 944.296190] usb 2-2: new full speed USB device using uhci_hcd and address 3 [ 944.438251] usb 2-2: not running at top speed; connect to a high speed hub [ 944.709928] usbcore: registered new interface driver uas [ 944.729999] Initializing USB Mass Storage driver...

Is there any way to fix this? Any idea why this problem occurred ?

  • How to get more information from the system crash

    - by viraptor
    I'd like to debug an issue I'm having with a linux (debian stable) server, but I'm running out of ideas of how to confirm any diagnosis. Some background: The servers are running DL160 class with hardware raid between two disks. They're running a lot of services, mostly utilising network interface and CPU. There are 8 cpus and 7 "main" most cpu-hungry processes are bound to one core each via cpu affinity. Other random background scripts are not forced anywhere. The filesystem is writing ~1.5k blocks/s the whole time (goes up above 2k/s in peak times). Normal CPU usage for those servers is ~60% on 7 cores and some minimal usage on the last (whatever's running on shells usually). What actually happens is that the "main" services start using 100% CPU at some point, mainly stuck in kernel time. After a couple of seconds, LA goes over 400 and we lose any way to connect to the box (KVM is on it's way, but not there yet). Sometimes we see a kernel reporting hung task (but not always): [118951.272884] INFO: task zsh:15911 blocked for more than 120 seconds. [118951.272955] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [118951.273037] zsh D 0000000000000000 0 15911 1 [118951.273093] ffff8101898c3c48 0000000000000046 0000000000000000 ffffffffa0155e0a [118951.273183] ffff8101a753a080 ffff81021f1c5570 ffff8101a753a308 000000051f0fd740 [118951.273274] 0000000000000246 0000000000000000 00000000ffffffbd 0000000000000001 [118951.273335] Call Trace: [118951.273424] [<ffffffffa0155e0a>] :ext3:__ext3_journal_dirty_metadata+0x1e/0x46 [118951.273510] [<ffffffff804294f6>] schedule_timeout+0x1e/0xad [118951.273563] [<ffffffff8027577c>] __pagevec_free+0x21/0x2e [118951.273613] [<ffffffff80428b0b>] wait_for_common+0xcf/0x13a [118951.273692] [<ffffffff8022c168>] default_wake_function+0x0/0xe .... This would point at raid / disk failure, however sometimes the tasks are hung on kernel's gettsc which would indicate some general weird hardware behaviour. It's also running mysql (almost read-only, 99% cache hit), which seems to spawn a lot more threads during the system problems. During the day it does ~200kq/s (selects) and ~10q/s (writes). The host is never running out of memory or swapping, no oom reports are spotted. We've got many boxes with similar/same hardware and they all seem to behave that way, but I'm not sure which part fails, so it's probably not a good idea to just grab something more powerful and hope the problem goes away. Applications themselves don't really report anything wrong when they're running. I can run anything safely on the same hardware in an isolated environment. What can I do to narrow down the problem? Where else should I look for explanation?

  • Rsync: windows 7, synology: login error and permission denied error

    - by loonboon
    Good day to all of you all, I'm running into strange/stupid errors, and I hope anybody would be so kind to help me out. I have to admit, I am by no means a guru, so please bear with me :-) Situation: -Synology NAS (runs Linux), and Windows 7 desktop (1 normal/restricted user Lisa and 1 admin user). - Data from W7 desktop to be rsynced to synology: /volume1/home/Lisa/Backup - Rsync command: c:\cygwin\bin\rsync -avz /cygdrive/e/Lisa/ [email protected]:/volume1/homes/Lisa/Backup - I've set up ssh per these two threads: a. http://www.cesareriva.com/archives/102 b. http://www.cesareriva.com/archives/112 Now the horrors begin: - root is allowed to run the rsync succesfully, however, he doesn't login automatically (so I can not use rsync in W7 batchscripts, which is of course required). - Lisa is allowed to login automatically but he can not succesfully finish the rsync command because of permission errors: rsync change dir /volume1/homes/Lisa/Backup failed: permissions denied. This happens for each and every file and subdir rsync tries to create. However, the main directory (Backup) is created. When I try to copy files from windows explorer to the directory 'Backup' using the very same user Lisa everything goes smoothly. So, obviously, there is a permission problem somewhere; either my rsync-command isn't correct, or the folder permissions for homes/Lisa aren't correct (but, then again, Windows 7 copies files to that folder without any problems, so that does make me believe the homes/Lisa-permissions don't appear to be the problem). I also tried adding: --chmod=Dugo+x --chmod=ugo+r which I found somewhere on the web, to the rsync-command, but this didn't solve any problem and gave the exact errors. Would anybody please please help me on how to fix this? I am utterly frustrated about this, because I have been trying for 1 month to get everything to work and it simply doesn't work. I bought the big Synology to end the horrors of 20 external USB-disks for once and for all (we have many pictures and home vids of our deceased dogs and want to watch these, the horrors being 'what material is on what disk'). I'll gladly return the favour of somebody helping me out by buying you a nice beer (paypal), if you could end my misery. I am not extremely skilled on Linux (not at all :-( ) so if you could give an extra word when possible so I understand what to do, I'd be very grateful. I really hope somebody can help me out, Thank you in advance, Lisa

  • Lag spikes at full CPU usage, maybe video card

    - by Roberts
    I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).

  • XP shared folders not accessible after BIOS changed

    - by stijn
    Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

  • Linux per-process resource limits - a deep Red Hat Mystery

    - by BobBanana
    I have my own multithreaded C program which scales in speed smoothly with the number of CPU cores.. I can run it with 1, 2, 3, etc threads and get linear speedup.. up to about 5.5x speed on a 6-core CPU on a Ubuntu Linux box. I had an opportunity to run the program on a very high end Sunfire x4450 with 4 quad-core Xeon processors, running Red Hat Enterprise Linux. I was eagerly anticipating seeing how fast the 16 cores could run my program with 16 threads.. But it runs at the same speed as just TWO threads! Much hair-pulling and debugging later, I see that my program really is creating all the threads, they really are running simultaneously, but the threads themselves are slower than they should be. 2 threads runs about 1.7x faster than 1, but 3, 4, 8, 10, 16 threads all run at just net 1.9x! I can see all the threads are running (not stalled or sleeping), they're just slow. To check that the HARDWARE wasn't at fault, I ran SIXTEEN copies of my program independently, simultaneously. They all ran at full speed. There really are 16 cores and they really do run at full speed and there really is enough RAM (in fact this machine has 64GB, and I only use 1GB per process). So, my question is if there's some OPERATING SYSTEM explanation, perhaps some per-process resource limit which automatically scales back thread scheduling to keep one process from hogging the machine. Clues are: My program does not access the disk or network. It's CPU limited. Its speed scales linearly on a single CPU box in Ubuntu Linux with a hexacore i7 for 1-6 threads. 6 threads is effectively 6x speedup. My program never runs faster than 2x speedup on this 16 core Sunfire Xeon box, for any number of threads from 2-16. Running 16 copies of my program single threaded runs perfectly, all 16 running at once at full speed. top shows 1600% of CPUs allocated. /proc/cpuinfo shows all 16 cores running at full 2.9GHz speed (not low frequency idle speed of 1.6GHz) There's 48GB of RAM free, it is not swapping. What's happening? Is there some process CPU limit policy? How could I measure it if so? What else could explain this behavior? Thanks for your ideas to solve this, the Great Xeon Slowdown Mystery of 2010!

  • How to delete files and folders that cannot be deleted?

    - by glenneroo
    I have a backup copy of a previous Windows' Documents and Settings folder which only contains my original user and within 2 more directories: Favorites and Local Settings. When I try to delete Local Settings I get this error: When I try to delete Favorites, I get this error: I ran this in a cmd shell: attrib *.* -r -a -s -h /s ...but it did not help, nor did it return any errors/warnings. I used Unlocker v1.8.5 and LockHunter repeatedly at multiple levels to see if any files are in use, but both always say: No Files Locked. Update #1: I was able to rename the directory, which now gives me this warning before (trying to) delete: If I press Yes (or Yes to All) then I get this error: Update #2: I let chkdsk /f run which required a reboot since it's on my primary system partition. During Stage 2 scanning, I received about 40 of these: Deleting an index entry from index $0 of file 25. ...followed by: Deleting index entry cookies in index $I30 of file 37576. ...but I still get the first error dialog above when trying to delete. I ran chkdsk again, this time: chkdsk /f /r. Produced no messages. Same result when deleting. Update #3: Digging deeper, the 99 is the name of one of many directories located deep in here: C:\Documents and Settings.OLD\User\Local Settings\Application Data\Microsoft\Messenger\[email protected]\SharingMetadata\[email protected]\DFSR\Staging\CS{D4E4AE55-B5E2-F03B-5189-6C4DA6E41788}\ Inside each of those directories were files with names such as: 2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-Downloaded.frx I noticed that, unlike all the directories, I couldn't rename any of these files. I also noticed that the file + dir names were extremely long: Original directory = 194 characters Filenames = 100+ characters Together the length exceeds the 255-char limit which is bad and would explain the error message I posted in Update #1. Partial Solution: Rename all directories until the total path length is less than 100. Afterwards I was able to rename the .frx files, not to mention delete everything inside the Local Settings directory. This is only a partial solution because these (empty) directories are still not deleteable, C:\1\2\Favorites\Wien\What To Do.. C:\1\2\Favorites\Photography\FIRE Same error as above: Here is what Explorer properties shows for both folders: Update #4 (another partial solution): Using harrymc's answer combined with thoroughly reading through this amazing MS-KB article which contains nearly everyone's idea and then some, inconspicuously titled: You cannot delete a file or a folder on an NTFS file system volume. I was able to delete the 2nd folder C:\1\2\Favorites\Photography\FIRE - the problem being that there was an invisible trailing space at the end. I got lucky when I did an auto-complete whilst playing around with the del "\\?\<path>" command which he suggested. NOTE: A normal del did NOT work, nor did deleting from explorer. Now all that is left is the first directory C:\1\2\Favorites\Wien\What To Do.. (yes I tried endlessly with multiple combinations of the above solution ;) Keep 'em coming! =)

  • Can't connect to svnserve on localhost - connection actively refused

    - by RMorrisey
    When I try to connect using Tortoise to my SVN server using: svn://localhost/ Tortoise tells me: "Can't connect to host 'localhost'. No connection could be made because the target machine actively refused it." How can I fix this? I am trying to set up a subversion server on my local PC for personal use. I am running Windows Vista, with SlikSVN and TortoiseSVN installed. I previously had everything working correctly, but I found that I couldn't merge(!), apparently due to a version mismatch between the SVN client and server. Anyway...

  • long access times and errors in iis application

    - by Jens Olsson
    Hi, I am having an issue with an IIS application (details of environment at the end of the message). The web site works great most of the time and I cannot reproduce any error in our test system. On the live system however with on averare of 5-15 requests per second I have a problem with that some requests (about 0.05%) will take over 300 seconds to complete. The other requests complete withing 5-10 seconds. It seem like if all the errornous requests end up with a Timer_EntityBody error in the error log. I have never seen this as an end user but I guess that they will receive some kind of error message. I am trying to find out what can be causing this errornous behaviour. Any ideas are welcome. I have read something about that there can be an MTU issue if ICMP and MTU protocols are blocked in the firewall. Does that sound reasonable? I have also read about updating to IIS 7 should do the trick. Does it sound reasonable? I think that the problem has another cause but I have no idea of what. I have tried running hte perormance monitor, monitoring for database locks and active transaction counts. I can see some of these in the perfmon log for the MSSQL server (another machine) for example: Active transactions is sometimes peaking and sometimes for long periods Lock waits per seconds is sometimes peaking Transactions per second is sometimes peaking Page IO Latch wait is sometimes peaking Lock wait time (ms) is sometimes peaking But I cannot see that any of these correlate to the errors in the IIS error log. On the IIS server machine I can also see with perfmon that some values peak a few times during a day: Request execution time Avg disk queue length I can neither see that any of these correlate to the errors in the IIS error log. In the below code I have anonymized by replacing some parts with HIDDEN The following can be seen in the access log 2010-10-01 08:35:05 W3SVC1301873091 **HIDDEN** POST /**HIDDEN**/Modules/BalanceModule.aspx - 80 - **HIDDEN** Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) ASP.NET_SessionId=**HIDDEN** 400 0 64 0 2241 127799 At the same time the following can be seen in the error log: 2010-10-01 08:35:05 **HIDDEN** 1999 **HIDDEN** 80 HTTP/1.0 POST /**HIDDEN**/Modules/BalanceModule.aspx - 1301873091 Timer_EntityBody Test+Pool I can tell the following about the environment: Server: Windows Server 2003 x64 SP2 running on VMWare HTTP Server: IIS v6.0 with ASP.NET 2.0.50727 Antivirus: Trend Micro OfficeScan (Is it a good idea to have this on a server?)

  • Microsoft Office 2003 document (Excel and Word) intermitently, takes 30 seconds to load

    - by Julio Nobre
    I am trying to figure out why a simple .XLS EXCEL workbook is taking, randomly, 30 seconds to open. Before answering: Please, bear mind the following: Problem symptoms Hanging is intermitent and it takes exactly 30 seconds; During hanging there is no cpu or disk activity; It only happens during document load. Every runs smooth after that; Windows Explorer.exe hangs on folder, but all other folders, system and applications are still responsive; There are no consecutive hangings. I have to wait for while to reproduce this behaviour; All samples documents are located on a local drive (C:\BPI); The no document has has macros and have any addins usage; The problem does occurs on others files extensions like .PDF, for example; Office 2003 is being used for several years; The computer is running Windows XP; Computer has several network mapped drives, all addressed to main file server; Recently, main fileserver was replaced by Windows 2011 SBS Standard Edition What I have done so far I have traced machine Explorer.exe, using Process Monitor, added Duration column, and filtered by Duration 1. That's is how I found that hanging was taking exactly 30 seconds. For further information, please refer to Oliver Salzburg tutorial. Using Process Monitor, I have also figured out than five operations were taking most of sample collecting duration. Looking at sample image below, column Operation below you will notice that one single operation was taking 29 seconds; I have tried different documents (.xls and .doc), all of them smaller than 30 KB; I have, temporarily, removed all shortcuts on User Document's folder that were pointing to network drives or shares; I have runned CCleaner to fix registry issues; I made sure that there were no external links on tested workbook or word documents; I have reproduced this behaviour for hours; I have extensivelly researched for hours on the web; Process Monitor's collected and filtered data

  • How to get an inactive RAID device working again?

    - by Jonik
    After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

  • Operative systems on SD cards

    - by HisDudeness
    I was getting some wild ideas the last days, like putting some operative systems into SD cards rather than on my hard drive. I'll go further into details now and explain what lead me to consider this probably abominable decision. I am on a laptop (that means I have a native SD-card reader) which is currently running a cross-distro setup, with a bunch of Linux systems (placed in dedicated ext4 logical partitions into a huge extended one) regulated by an unique GRUB. Since today, my laptop haven't even seen any Windows system with binoculars. I was thinking about placing all the os part of my setup into a Secure Digital to save all my 500 Gb Hard Drive for documents, music, videos and so on, and being able to just remove the SD and boot my system into another computer too, as well as having the possibility of booting other systems into mine by just plugging in another SD, without having to keep it constantly placed in my PC. Also, in the remote case in the near future I just wanted to boot Windows 8 in it, I read it causes major boot incompatibility issues with other systems by needing a digital signature in order for them to start. By having it in a removable drive, I could just get rid of it when I'm needing him and switch its card with Linux one, and so not having any obstacles to their boot. Now, my questions are: I know unlikely traditional rotating disk drives, integrated circuits ones have a limited lifespan in terms of cluster rewriting. Is it an obstacle to that kind of usage? I mean, some Ultrabooks are using SSD now, is it the same issue, or there are some differences between Solid State Drives and Secure Digitals in that sense? Maybe having them to store system files which are in fixed positions (making the even-usage of cluster technology useless) constantly being re-read and updated and similar things just gets them soon unserviceable, do it? Second question: are all motherboards and BIOSes able to boot from SDs just like they are from USB pen drives (I mean, provided card reader is USB-connected, isn't it)? Or can't bootloaders like GRUB be installed on SDs working? If they can't, is it a solution installing GRUB to MBR and making boot option pointing to SD? Will it work? Are there any other problems to installing OSs on a Secure Digital?

  • Using different SSDs types (not only SATA based) as system drive

    - by Hubert Kario
    Currently I have a Thinkpad X61s and want to make it both a bit faster and a bit more power efficient. For that reason I thought that adding SSD drive would make most sense. Unfortunately, because of financial reasons, buying SSD of over 200GB capacity is out of reach for me (not only it would be worth more than the rest of the laptop, but also I currently have a 500GB drive in it, so even such a drive would be kind of a downgrade for me). During preliminary testing with a cheap Transcend 4GB Class 6 (14MiB/s streaming, 9MiB/s random read) card I experienced boot times to be reduced by half so putting the OS only on it would already would be an improvement. Unfortunately, my system now is about 11GiB in size so anything less than 16GB would be constraining. In this laptop I can connect additional drives on at least 5 different ways: using SATA-ATA converter caddy in the X6 Ultrabase using internal mini PCIe slot using integrated SDHC slot using CardBus (a.k.a PCMCIA or PC Card) slot using USB Thankfully, because I use only Linux on this PC the bootability of them is irrelevant as I can put the /boot partition on internal HDD and / on any of the above mentioned Flash memories (as I already did for the SDHC test). From what I was able to research and from my own experience those options come with rather big downsides or other problems: SATA-ATA caddy It has three downsides: I have to carry the Ultrabse with me at all times (it's not really inconvenient, but those grams do add) and couldn't disconnect it when I want to disconnect the battery It makes the bay unusable for the optical drive and occasional quick access to other hard drives the only caddies I could buy have rather flaky controllers in them so putting my OS on it would hamper its stability Internal mini PCIe slot This would be an ideal solution, if only I could find real PCIe SSDs, not only devices that could talk only SATA or ATA over PCIe mechanical connection (the ones used in Dell Mini or Asus EEE). Theoretically Samsung did release such devices but I couldn't find them in retail anywhere. Integrated SDHC slot It's a nice solution with a single drawback: the fastest 16GB SDHC card on the market can only do around 35MiB/s read and 15MiB/s write while still costing like a normal 40GB SATA SSD that's 10 times faster. Not really cost-effective. CardBus (a.k.a PCMCIA or PC Card) slot Those cards are much faster than the SDHC option (there are ones that can do well over 50MiB/s read in benchmarks) and from what I could find the PCMCIA controller in my laptop does support UDMA so it should be able to deliver comparable speeds. They still cost similarly to SD cards but at least they provide streaming performance comparable to my current HDD. USB That's the worst option. Not only is it limited to 20-30MiB/s by the interface itself the drive would stick out of the laptop so it's a big no no. The question As such I think that going the "CF in a CardBus adapter" route will be the best option. My question is: did anyone try using CF cards in CardBus adapters as system drives with Linux on Thinkpad laptops? Laptops in general? What was the real-world performance? I don't have any CF cards so I can't check how well does it work with suspend/resume, or whatever it's easy to make it work in initramfs (I'm using ArchLinux and SD card was trivial — add 3 modules in single config line and rebuilding initramfs) so any tips/gotchas on this are welcome as well.

  • Event ID 17890 (A significant part... paged out.) with SQL Server 2008

    - by Godeke
    I have a machine that has SQL Server 2008 Standard installed. Periodically (about once an hour) I am getting Event ID 17890 several times in a row. An example: 6:28:54 "A significant part of sql server process memory has been paged out. This may result in a performance degradation. Duration: 0 seconds. Working set (KB): 10652, committed (KB): 628428, memory utilization: 1%%. 6:34:27 "A significant part of sql server process memory has been paged out. This may result in a performance degradation. Duration: 332 seconds. Working set (KB): 169780, committed (KB): 546124, memory utilization: 31%%." 6:38:55 "A significant part of sql server process memory has been paged out. This may result in a performance degradation. Duration: 600 seconds. Working set (KB): 245068, committed (KB): 546124, memory utilization: 44%%." This pattern repeated at 7:26 - 7:37, 8:26 - 8:36, 9:24 - 9:35 and so with the same increasing working set and memory utilization pattern. I don't have any (known) background tasks running at this time. Backups run at 2:00 This subsided from 11:00 at night until it resumed at 4:00 in the morning and has been continuing the intermittent 10 minute glitch periods. As this server has plenty of RAM (the commit charge has peaked at 2,871,564 of 4,194,012 physical) I disabled the paging files after reading several items I dug up searching Google and not finding any of them changing the situation. This pattern I am documented is after removing the paging files, so I'm not even sure where we are paging the SQL process could be going. I also changed the SQL process memory to have a minimum of 500MB and a maximum of 2GB of RAM (as this is a light duty database server serving only a small workgroup). Has anyone encountered this? Prior to disabling the page files this error would cause 5 minutes of disk thrashing that disabled access to the databases, files, IIS webs and so on. Since disabling the page files it just logs strange things, but I'm not seeing a performance drop at least. Any suggestions would be welcome.

  • Force caching of handler output which actively resists caching

    - by deceze
    I'm trying to force caching of a very obnoxious piece of PHP script which actively tries to resist caching for no good reason by actively setting all the anti-cache headers: Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Content-Type: text/html; charset=UTF-8 Date: Thu, 22 May 2014 08:43:53 GMT Expires: Thu, 19 Nov 1981 08:52:00 GMT Last-Modified: Pragma: no-cache Set-Cookie: ECSESSID=...; path=/ Vary: User-Agent,Accept-Encoding Server: Apache/2.4.6 (Ubuntu) X-Powered-By: PHP/5.5.3-1ubuntu2.3 If at all avoidable I do not want to have to modify this 3rd party piece of code at all and instead just get Apache to cache the page for a while. I'm doing this very selectively to only very specific pages which have no real impact on session cookies or the like, i.e. which do not contain any personalised information. CacheDefaultExpire 600 CacheMinExpire 600 CacheMaxExpire 1800 CacheHeader On CacheDetailHeader On CacheIgnoreHeaders Set-Cookie CacheIgnoreCacheControl On CacheIgnoreNoLastMod On CacheStoreExpired On CacheStoreNoStore On CacheLock On CacheEnable disk /the/script.php Apache is caching the page alright: [cache:debug] AH00698: cache: Key for entity /the/script.php?(null) is http://example.com:80/the/script.php?

[cache_disk:debug] AH00737: commit_entity: Headers and body for URL http://example.com:80/the/script.php? cached. However, it is always insisting that the "cached response isn't fresh" and is never serving the cached version. I guess this has to do with the Expires header, which marks the document as expired (but I don't know whether that's the correct assumption). I've tried to overwrite and unset headers using mod_headers, but this doesn't help; whatever combination I try the cache is not impressed at all. I'm guessing that the order of operation is wrong, and headers are being rewritten after the cache sees them. early header processing doesn't help either. I've experimented with CacheQuickHandler Off and trying to set explicit filter chains, but nothing is helping. But I'm really mostly poking in the dark, as I do not have a lot of experience with configuring Apache filter chains. Is there a straight forward solution for how to cache this obnoxious piece of code?

  • Is this distributed database server idea feasible?

    - by David
    I often use SQLite for creating simple programs in companies. The database is placed on a file server. This works fine as long as there are not more than about 50 users working towards the database concurrently (though depending on whether it is reads or writes). Once there are more than this, they will notice a slowdown if there are a lot of concurrent writing on the server as lots of time is spent on locks, and there is nothing like a cache as there is no database server. The advantage of not needing a database server is that the time to set up something like a company Wiki or similar can be reduced from several months to just days. It often takes several months because some IT-department needs to order the server and it needs to conform with the company policies and security rules and it needs to be placed on the outsourced server hosting facility, which screws up and places it in the wrong localtion etc. etc. Therefore, I thought of an idea to create a distributed database server. The process would be as follows: A user on a company computer edits something on a Wiki page (which uses this database as its backend), to do this he reads a file on the local harddisk stating the ip-address of the last desktop computer to be a database server. He then tries to contact this computer directly via TCP/IP. If it does not answer, then he will read a file on the file server stating the ip-address of the last desktop computer to be a database server. If this server does not answer either, his own desktop computer will become the database server and register its ip-address in the same file. The SQL update statement can then be executed, and other desktop computers can connect to his directly. The point with this architecture is that, the higher load, the better it will function, as each desktop computer will always know the ip-address of the database server. Also, using this setup, I believe that a database placed on a fileserver could serve hundreds of desktop computers instead of the current 50 or so. I also do not believe that the load on the single desktop computer, which has become database server will ever be noticable, as there will be no hard disk operations on this desktop, only on the file server. Is this idea feasible? Does it already exist? What kind of database could support such an architecture?

  • Should use EXT4 or XFS to be able to 'sync'/backup to S3?

    - by Rafa
    It's my first message here, so bear with me... (I have already checked quite a few of the "Related Questions" suggested by the editor) Here's the setup, a brand new dedicated server (8GB RAM, some 140+ GB disk, Raid 1 via HW controller, 15000 RPM) it's a production web server (with MySQL in it, too, not just serving web requests); not a personal desktop computer or similar. Ubuntu Server 64bit 10.04 LTS We have an Amazon EC2+EBS setup with the EBS volume formatted as XFS for easily taking snapshots to S3, via AWS' console. We are now migrating to the dedicated server and I want to be able to backup our data to Amazon's S3. The main reason being the possibility of using the latest snapshot from an EC2 instance in case of hardware failure on the dedicated server. There are two approaches I am thinking of: do a "simple" file-based backup with rsync, dumping the database' and other files, and uploading to amazon via S3 API commands, or to an EC2 instance, or something. do a file-system "freeze" (using XFS) with the usual ebs/ec2 snapshot tool to take part of the file system, take a snapshot, and upload it to Amazon. Here's my question (or series of questions): Can I safely use XFS for the whole system as the main and only format on the dedicated server? If not, is it safe to use EXT4? Or should I use something else? would then be possible to make snapshots of the system to upload to Amazon? Is it possible/feasible/practical to do what I want to do, anyway? any recommendations? When searching around for S3/EBS/XFS, anything relevant to my problem is usually focused on taking snapshots of a XFS system that is already an EBS volume. My intention is to do it in a "real"/metal dedicated server. Update: I just saw this on Wikipedia: XFS does not provide direct support for snapshots, as it expects the snapshot process to be implemented by the volume manager. I had always assumed that I could choose 2 ways of doing snapshots: via LVM or via XFS (without LVM). After reading this, I realize these 2 options are more like it: With XFS: 1) do xfs_freeze; 2) copy the frozen files via, eg, rsync; 3) unfreeze xfs With LVM and XFS: 1) do xfs_freeze; 2) make a binary copy of the frozen fs via lvcreate and related commands; 3) unfreeze xfs; 4) somehow backup the LVM snapshot. Thanks a lot in advance, Let me know if I need to clarify something.

  • Monitoring tools that can take high rate and high volume?

    - by Jon Watte
    We're using Cacti with RRDTool to monitor and graph about 100,000 counters spread across about 1,000 Linux-based nodes. However, our current setup generally only gives us 5-minute graphs (with some data being minute-based); we often make changes where seeing feedback in "near real time" would be of value. I'd like approximately a week of 5- or 10-second data, a year of 1-minute data, and 5 years of 10-minute data. I have SSD disks and a dual-hexa-core server to spare. I tried setting up a Graphite/carbon/whisper server, and had about 15 nodes pipe to it, but it only has "average" for the retention function when promoting to older buckets. This is almost useless -- I'd like min, max, average, standard deviation, and perhaps "total sum" and "number of samples" or perhaps "95th percentile" available. The developer claims there's a new back-end "in beta" that allows you to write your own function, but this appears to still only do 1:1 retention (when saving older data, you really want the statistics calculated into many streams from a single input. Also, "in beta" seems a little risky for this installation. If I'm wrong about this assumption, I'd be happy to be shown my error! I've heard Zabbix recommended, but it puts data into MySQL or some other SQL database. 100,000 counters on a 5 second interval means 20,000 tps, and while I have an SSD, I don't have an 8-way RAID-6 with battery backup cache, which I think I'd need for that to work out :-) Again, if that's actually something that's not a problem, I'd be happy to be shown the error of my ways. Also, can Zabbix do the single data stream - promote with statistics thing? Finally, Munin claims to have a new 2.0 coming out "in beta" right now, and it boasts custom retention plans. However, again, it's that "in beta" part -- has anyone used that for real, and at scale? How did it perform, if so? I'm almost thinking about using a graphing front-end (such as Graphite) and rolling my own retention backend with a simple layer on top of mmap() and some stats. That wouldn't be particularly hard, and would probably perform very well, letting the kernel figure out the balance between frequency of flushing to disk and process operations. Any other suggestions I should look into? Note: it has to have shown itself able to sustain the kinds of data loads I'm suggesting above; if you can point at the specific implementation you're referencing, so much the better!

  • How can I recover an ext4 filesystem corrupted after a fsck?

    - by Regan
    I have an ext4 filesystem on luks over software raid5. The filesystem was operating "just fine" for several years when I was beginning to run out of space. I had a 9T volume on 6x2T drives. I began upgrading to 3T drives by doing the mdadm fail, remove, add, rebuild, repeat process until I had a larger array. I then grew the luks container, and then when I unmounted and tried to resize2fs I was given the message the filesystem was dirty and needed e2fsck. Without thinking I just did e2fsck -y /dev/mapper/candybox and it began spewing all kinds of inode being removed type messages (can't remember exactly) I killed e2fsck and tried to remount the filesystem to backup data I was concerned about. When trying to mount at this point I get: # mount /dev/mapper/candybox /candybox mount: wrong fs type, bad option, bad superblock on /dev/mapper/candybox, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Looking back at my older logs I noticed the filesystem was giving this error each time the machine booted: kernel: [79137.275531] EXT4-fs (dm-2): warning: mounting fs with errors, running e2fsck is recommended So shame on me for not paying attention :( I then tried to mount using every backup superblock (one after another) and each attempt left this in my log: EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 0 failed (26534!=65440) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 1 failed (38021!=36729) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 2 failed (18336!=39845) ...

[mount:2939] Attempts to restart e2fsck results in: # e2fsck /dev/mapper/candybox e2fsck 1.41.14 (22-Dec-2010) e2fsck: Group descriptors look bad... trying backup blocks... candy: recovering journal e2fsck: unable to set superblock flags on candy At this point, I decided it best to order some more drives and make an image using ddrescue Now two weeks later I have an image of the luks partition in a .img file. # ls -lh total 14T -rw-r--r-- 1 root root 14T Oct 25 01:57 candybox.img -rw-r--r-- 1 root root 271 Oct 20 14:32 candybox.logfile After numerous attempts using everything I could find online I could not coerce e2fsck to do anything on the image, so I used mkfs.ext4 -L candy candybox.img -m 0 -S and I was able to mount the dirty filesystem readonly without the journal and recover 960G of data. It gave all kinds of errors of various directories not existing and so forth but I was able to get some stuff. Which gave me some hope! I then ran e2fsck again and it had to recreate the root inode and gave a massive list of correcting group counts, I accepted the root inode creation and said no to everything else, leaving a completely empty filesystem. Re-ran again and said yes to all questions with the same result but now a "clean" but empty filesystem. extundelete gives me 0 recoverable inodes found. And now I'm stuck again, I can't come up with any other methods other than dropping to something like photorec which will give me an absolute mess with how large the filesystem was. I'm willing to re-copy the image from the original array and start over, if I can get any suggestions or ideas on a way to get more of my files back. I wish I could give more detailed logs of the commands that have run, but the output is long scrolled passed except for what gets logged to syslog and my memory is not as detailed due to the timeframe this has occurred over. Any help is greatly appreciated!

  • Cobbler 2.2.2 problems

    - by Peter
    I have setup a dedicated LAN for Cobbler tests. My setup is: Cobbler server: openSUSE 12.3, cobbler 2.2.2 (from openSUSE repos) Imported distros: Centos 6.5, Red Hat 6.5, Red Hat 7.0, openSUSE 13.1 Target Machine: VMs in a Windows 7 Virtualbox Systems provisioning works OK, but I have some problems. The first one is that cobbler does not honor the "pxe_just_once: 1" setting. When the setup of the target OS is finished, after the reboot the target systems continues to PXE boot! The second problem is that the target server is not correctly configured! See my setup: cobbler system report --name=test Name : test TFTP Boot Files : {} Comment : Fetchable Files : {} Gateway : 192.168.0.1 Hostname : testcob1.example.com Image : IPv6 Autoconfiguration : False IPv6 Default Device : Kernel Options : {} Kernel Options (Post Install) : {} Kickstart : <<inherit>> Kickstart Metadata : {} LDAP Enabled : False LDAP Management Type : authconfig Management Classes : [] Management Parameters : <<inherit>> Monit Enabled : False Name Servers : ['192.168.0.1', '8.8.8.8'] Name Servers Search Path : [] Netboot Enabled : False Owners : ['admin'] Power Management Address : Power ID : Power Password : Power Management Type : ipmitool Power Username : Profile : RHEL-6.5-x86_64 Proxy : <<inherit>> Red Hat Management Key : <<inherit>> Red Hat Management Server : <<inherit>> Repos Enabled : False Server Override : <<inherit>> Status : testing Template Files : {} Virt Auto Boot : <<inherit>> Virt CPUs : <<inherit>> Virt Disk Driver Type : <<inherit>> Virt File Size(GB) : <<inherit>> Virt Path : <<inherit>> Virt RAM (MB) : <<inherit>> Virt Type : <<inherit>> Interface ===== : eth0 Bonding Opts : Bridge Opts : DHCP Tag : DNS Name : Master Interface : Interface Type : IP Address : 192.168.0.200 IPv6 Address : IPv6 Default Gateway : IPv6 MTU : IPv6 Secondaries : [] IPv6 Static Routes : [] MAC Address : Management Interface : True MTU : Subnet Mask : 255.255.255.0 Static : True Static Routes : [] Virt Bridge : So, although I have setup the hostname and the network interface of the target system, after the setup, the hostname is set to localhost.localdomain and eth0 is configured as a DHCP not static! How can I find the problem and fix it? Note that I have synced and restarted cobbler a couple of times, but the problems persists.

  • Why Does My Windows 7 PC Freeze After Waking from Sleep?

    - by Blaenk
    Hey guys. I have Windows 7 running on my computer and everything is perfect. There's only one little problem. Sometimes when I leave my computer, I come back and my monitor is turned off or asleep, whichever it is. This is fine, I set it to do this. However, after turning on the monitor and moving the mouse around, the mouse cursor freezes; both the keyboard and mouse don't respond to anything, for example the keyboard's windows key won't bring up the start menu and moving the mouse around does not move the cursor around on the screen. I have to wait about a minute or two before things start working again. I figured this was a power savings setting problem, so I went into Control Panel Power Options. I only have Turn off Display = 30 minutes and Put Computer to Sleep = Never. Of course, I went into the advanced power settings to look through there. I put Never to turn off the hard disk, Sleep after never, and that's about it. Nothing else there looks like it might be causing this. I went into the device manager and checked the mouse and the keyboard, and they both have the Allow this device to wake the computer checked for both of them. Perhaps this other bit of information might help: Sometimes I VNC into my PC using my MacBook, and sometimes, as soon as it shows me the desktop, the same thing happens. The mouse won't move and VNC won't register any events on the server (Which is my PC of course). I close the client (And I know it has nothing to do with the client), then immediately restart it and try to connect. When I click the connect button, it hangs there, as if the PC is not responding. Basically it's like whenever I try to wake the computer from sleep, it does so by showing me the desktop, then it freaks out. Then again, I guess the computer isn't sleeping because the setting is set to 'Sleep after = Never'. I honestly don't know what's going on, would appreciate any insight. Thanks!

  • Spotlight Infinite Indexing issue (external data drive)

    - by Manca Weeks
    This is an external drive, formerly a boot drive which is now in use only to access music files (sibelius, audio, midi, live, logic etc.) without transferring the data into a new boot system, partly because of the issue I am about to describe, but mostly because the majority of the data is mainly there for archival purposes. The user is a composer and prominent musician and needs to be able to rehash the data at will. I have tried several things - here is a list: - make complete filesystem clone with antonio diaz's ddrescue - run Disk Warrior on copy, repair whatever errors occurred - wipe out all ACLs on entire drive - set all permissions to the same value - wide open 777 - remove any system data (applications, system files, including hidden files to the best of my knowledge) by selecting only non-system/app data and using Carbon Copy Cloner to put only the data of interest onto a newly formatted drive - transfer data to newly formatted drive folder by folder, resetting the spotlight index in between adding each to observe for issues (interesting here is that no issues occurred except for in Documents folder - when I transferred only the Documents folder to a newly formatted drive on its own - no trouble. It appears almost as thought it may not be the content but the quantity or specific combination of data that results in problems) - use DataRescue to transfer the data to yet another newly formatted drive to expose any missed hidden files Between each of the above steps I stopped Spotlight (search for anything beginning with md in Activity Monitor - All Processes and quitting it), deleted the .Spotlight-V100 directory from the affected drive. Restart Splotlight indexing by adding drive to Spotlight privacy list and removing it. In each case the same issue occurs - Spotlight begins indexing normally (or so it seems), then the index estimated time increases, usually to 4 hours remaining. This is where it gets stuck and continues to predict 4 hours remaining but never finishes. Sometimes I can't eject the drive and have to quit the md.. processes from Activity Monitor to be able to eject the drive without Force Eject. Once I disconnect the drive after the 4 hours remaining situation - if I reattach it, Spotlight forever estimates remaining time and never gets going again. So there it is. It is apparently not a filesystem issue, not a permissions issue and not tied to any particular piece of hardware or protocol (used USB and FW drives). I have tried this on several machines (3 to be precise) and in 10.5.8 and 10.6.5. Simply disabling Spotlight on this volume is not an option because the owner has no clue where things are as the data on the volume dates back to music projects and compositions from 2003 and before. He needs to be able to query for results. Anyone got any ideas? Thanks, M

  • force unattended install php apt debian squeeze

    - by user1258619
    i am trying to do an unattended install via php for several packages but every time when the dependencies come up it aborts instead of forcing the answer to be yes. (i have broken apt a few times...) each time though i start off re-imaging my vps(testing server) so there isn't an issue of something still being hung or crashed.can someone tell me what i am doing wrong? keep in mind this is the 12th version of this script to get nowhere. fwrite(STDOUT, "Root Password:\n"); $root_pass = chop(fgets(STDIN)); $file_apt = '/etc/apt/apt.conf.d/70debconf'; // Open the file to get existing content $current_apt = file_get_contents($file_apt); // Append a new person to the file $current_apt .= "Dpkg::Options {\"--force-confold\";};\n"; // Write the contents back to the file file_put_contents($file_apt, $current_apt); $update = shell_exec('echo '.$root_pass.' | DEBIAN_FRONTEND=noninteractive sudo -S apt-get update'); echo $update; $update_upgrade = shell_exec('echo '.$root_pass.' | DEBIAN_FRONTEND=noninteractive sudo -s apt-get upgrade'); echo $update_upgrade; $install_unattended_mysql = shell_exec('echo '.$root_pass.' | DEBIAN_FRONTEND=noninteractive apt-get install --yes --force-yes mysql-server'); echo $install_unattended_mysql; $install_mysql_set_password = shell_exec('mysql -u root -e "UPDATE mysql.user SET password=PASSWORD("'.$root_pass.'") WHERE user="root"; FLUSH PRIVILEGES;'); echo $install_mysql_set_password; i have read a few places that i needed to edit the apt.conf file so i am doing so here and doing an update and an upgrade. also the upgrade does abort when it actually has to install something. The following packages will be upgraded: apache2 apache2-doc apache2-mpm-prefork apache2-utils apache2.2-bin apache2.2-common base-files bind9 bind9-host bind9utils debian-archive-keyring dpkg dselect libbind9-60 libc-bin libc6 libdns69 libisc62 libisccc60 libisccfg62 liblwres60 locales 22 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Need to get 18.4 MB of archives. After this operation, 8192 B of additional disk space will be used. Do you want to continue [Y/n]? Abort. I also should note that only a few pieces of software are going to be installed from the apt repo's as i will include some binaries to go along with it.
