• Access denied to mysql cause by invalid server hostname bind address

  - by Mark

  I cannot login to mysql using the terminal. [root@fst mysql]# mysql -h localhost -u admin -p Enter password: ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES) I am sure I have the correct password. The mysql is also running when I check status. The mysql database is also present in the directory /var/lib/mysql/. The host host.myi, host.myd and host.frm are present. By the way this a related to question on my previous problem MySQL server quit without updating PID file . Initially the problem arise when the root directory was full. To be able to login to directadmin and start mysql, I added a soft link of the /var/lib/mysql/ to /home/mysql. Since my database used up the most of the root directory. The root directory has 50Gb and /home has 1.5Gb. Somehow the /var/lib/mysql/idbdata1 is corrupted. So I move it to another location. Now, I can start the mysql server but I cannot login into it. Below are the contents from the myql logs. 121212 20:44:10 mysqld_safe mysqld from pid file /var/lib/mysql/fst.srv.net.pid ended 121212 20:44:10 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 121212 20:44:10 [Note] Plugin 'FEDERATED' is disabled. 121212 20:44:10 InnoDB: The InnoDB memory heap is disabled 121212 20:44:10 InnoDB: Mutexes and rw_locks use GCC atomic builtins 121212 20:44:10 InnoDB: Compressed tables use zlib 1.2.3 121212 20:44:10 InnoDB: Using Linux native AIO 121212 20:44:10 InnoDB: Initializing buffer pool, size = 128.0M 121212 20:44:10 InnoDB: Completed initialization of buffer pool 121212 20:44:10 InnoDB: highest supported file format is Barracuda. 121212 20:44:11 InnoDB: Waiting for the background threads to start 121212 20:44:12 InnoDB: 1.1.8 started; log sequence number 1595675 121212 20:44:12 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306 121212 20:44:12 [Note] - '0.0.0.0' resolves to '0.0.0.0'; 121212 20:44:12 [Note] Server socket created on IP: '0.0.0.0'. 121212 20:44:12 [Note] Event Scheduler: Loaded 0 events 121212 20:44:12 [Note] /usr/sbin/mysqld: ready for connections.

• Nginx phpmyadmin redirecting to / instead of /phpmyadmin upon login

• Excel: conditionally format a cell using the format of another, content-matching cell

  - by Eric A. Meyer

  I have an Excel spreadsheet where I’d like to be able to create a “key” of formatted cells with unique values, and then in another sheet format cells using the key formatting. So for example, my key is as follows, with one value per cell and the visual formatting indicated in parentheses: A (red background) B (green background) C (blue background) So that’s on one sheet (or in a remote corner of the current sheet—whichever is better). Then, in an area that I mark for conditional formatting, I can type one of those three letters and have the cell where I typed it visually formatted according to the key. So if I type a “B” into one of the conditionally formatted cells, it gets a green background. (Note that I’m using backgrounds here solely for ease of explanation: ideally I want to have all visual formatting copied over, whether it’s foreground color, background color, font weight, borders, or whatever. But I’ll take what I can get, obviously.) And—just to make it extra-tricky—if I change the formatting in the key, that change should be reflected in cells that reference the key. Thus, if I change the “B” formatting in the key from a green background to a purple background, any “B” in the main sheet should switch to the new color. Similarly, it should be possible to add or remove values from the key and have those changes applied to the main data set. I’m okay with the formatting-update-on-key-change being triggered by clicking a button or something. I suspect that if any of this is possible it will require VBA, but I’ve never used it so I’ve no idea where to start if that’s the case. I’m hoping it’s possible without VBA. I know it’s possible to just use multiple conditional formats, but my use case here is that I’m trying to create the above-described capability for someone who isn’t conversant with conditional formatting. I’d like to let them be able to define a key, update it if necessary, and keep on truckin’ without me having to rewrite the spreadsheet’s formatting rules for them. --- UPDATE --- So I think I was a bit unclear about my original request. Let me try again with an image. The image shows the “key” on the left, where values and styles are defined using keyboard and mouse input. On the right, you see the data that should be formatted to match the key. Thus if I type a “C” into a cell in the Data area, it should be blue-backed. Furthermore, if I change the formatting of “C” in the Key to have a purple background, all the “C” cells should switch from blue to purple. For further craziness, if I add more to the Key (say, “D” with a yellow background) then any “D” cells will be styled to match; if I remove a Key entry, then matching values in the Data area should revert to default styling. So. Is that more clear? Is it possible, in whole or in part? I don’t have to use conditional formatting for this; in fact, at this point I suspect I probably shouldn’t. But I’m open to any approach!

• Synergy 1.4.2 Linux server, OSX client, Media/Function key mapping issues

  - by at165dB

  I'm using an Apple bluetooth keybord to control my Linux synergy server. SSH tunneling, Mouse, Keyboard, and Copy&Paste all work. Linux sees all the media/app keys that are on top of the F# keys correctly. However if I press any of those keys while controlling my OSX client, nothing happens on the client. Running synergys with -d DEBUG1 I can see the following keycode info: Pressing the "dim monitor" key that also serves as F1 generates: new mask: 0x2000 event: KeyPress code=232, state=0x0010 new mask: 0x2000 If I press "fn" and the same key, I can see it sending what I'm assuming is an F1: event: KeyPress code=67, state=0x0010 onKeyDown id=61374 mask=0x2000 button=0x0043 send key down to "foo.cisco.com" id=61374, mask=0x2000, button=0x0043 new mask: 0x2000 event: KeyRelease code=67, state=0x0010 onKeyUp id=61374 mask=0x2000 button=0x0043 send key up to "foo.cisco.com" id=61374, mask=0x2000, button=0x0043 I'm guessing I need to tweak my synergy.conf so that the server sends keys that it currently isn't. I'm also not sure what I need to do to tweak the keys that it is sending, but are not working. Below are all the other keys I'm having issues with. Does anyone have any idea how I can enable their functionality? brighten monitor: new mask: 0x2000 event: KeyPress code=233, state=0x0010 new mask: 0x2000 expose: new mask: 0x2000 event: KeyPress code=128, state=0x0010 new mask: 0x2000 dashboard: new mask: 0x2000 event: KeyPress code=212, state=0x0010 new mask: 0x2000 dim keyboard: new mask: 0x2000 event: KeyPress code=237, state=0x0010 new mask: 0x2000 brighten keyboard: new mask: 0x2000 event: KeyPress code=238, state=0x0010 new mask: 0x2000 rewind: event: KeyPress code=173, state=0x0010 onKeyDown id=57521 mask=0x2000 button=0x00ad send key down to "foo.cisco.com" id=57521, mask=0x2000, button=0x00ad new mask: 0x2000 event: KeyRelease code=173, state=0x0010 onKeyUp id=57521 mask=0x2000 button=0x00ad send key up to "foo.cisco.com" id=57521, mask=0x2000, button=0x00ad play/pause: event: KeyPress code=172, state=0x0010 onKeyDown id=57523 mask=0x2000 button=0x00ac send key down to "foo.cisco.com" id=57523, mask=0x2000, button=0x00ac new mask: 0x2000 event: KeyRelease code=172, state=0x0010 onKeyUp id=57523 mask=0x2000 button=0x00ac send key up to "foo.cisco.com" id=57523, mask=0x2000, button=0x00ac fastforward: event: KeyPress code=171, state=0x0010 onKeyDown id=57520 mask=0x2000 button=0x00ab send key down to "foo.cisco.com" id=57520, mask=0x2000, button=0x00ab new mask: 0x2000 event: KeyRelease code=171, state=0x0010 onKeyUp id=57520 mask=0x2000 button=0x00ab send key up to "foo.cisco.com" id=57520, mask=0x2000, button=0x00ab mute: event: KeyPress code=121, state=0x0010 onKeyDown id=57517 mask=0x2000 button=0x0079 send key down to "foo.cisco.com" id=57517, mask=0x2000, button=0x0079 new mask: 0x2000 event: KeyRelease code=121, state=0x0010 onKeyUp id=57517 mask=0x2000 button=0x0079 send key up to "foo.cisco.com" id=57517, mask=0x2000, button=0x0079 volume down: onKeyDown id=57518 mask=0x2000 button=0x007a send key down to "foo.cisco.com" id=57518, mask=0x2000, button=0x007a new mask: 0x2000 event: KeyRelease code=122, state=0x0010 onKeyUp id=57518 mask=0x2000 button=0x007a send key up to "foo.cisco.com" id=57518, mask=0x2000, button=0x007a volume up: event: KeyPress code=123, state=0x0010 onKeyDown id=57519 mask=0x2000 button=0x007b send key down to "foo.cisco.com" id=57519, mask=0x2000, button=0x007b new mask: 0x2000 event: KeyRelease code=123, state=0x0010 onKeyUp id=57519 mask=0x2000 button=0x007b send key up to "foo.cisco.com" id=57519, mask=0x2000, button=0x007b eject: event: KeyPress code=169, state=0x0010 onKeyDown id=57345 mask=0x2000 button=0x00a9 send key down to "foo.cisco.com" id=57345, mask=0x2000, button=0x00a9 new mask: 0x2000 event: KeyRelease code=169, state=0x0010 onKeyUp id=57345 mask=0x2000 button=0x00a9 send key up to "foo.cisco.com" id=57345, mask=0x2000, button=0x00a9

• How to diagnose computer lockup/freezing problem

  - by Scott Mitchell

  I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularlity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Thanks

• Is the master database backup crucial for restoring MS SQL server in the event where you have to res

  - by Imagineer

  I have been advise by Commvault partner support to turn off the backup of the master database as the backup failed due to the log file being lock. The following is the advise given: "The message is caused by Commvault’s inability to backup the master database’s transaction log. If this is happening intermittently its possible that something is locking the transaction log, preventing SQL iData agent from accessing the log. Typically the master database is just a template and is not used by any applications (applications that do require the use of an SQL database create their own) so there should be no harm in preventing it from being backed up You can do this by nominating NOT to back it up in the primary copy for the SQL data agent" The following is the error that I get. sqlxx SQL Server/ SQLxx N/A/ System DBs 19856* (CWE) Transaction Log N/A 01/08/2010 19:00:16 (01/08/2010 19:00:18 ) 01/08/2010 19:03:15 (01/08/2010 19:03:14 ) 1.44 MB 0:01:11 0.071 2 0 1 ITD014L2 Failure Reason: • ERROR CODE [30:325]: Error encountered during backup.

• Troubleshooting major performance issue: Is culprit Intel RST, Hard drive, or something else?

  - by Sean Killeen

  The Setup I have the following components that come into play in this situation: ASUS P8Z68 V/PRO motherboard a RAID1 configuration (1x 1TB drive, 1 x 2TB drive -- I explain below), accelerated with an SSD using Intel's RST software, and 1 TB drive standing by as a spare. Core i7 2600k 32 GB RAM Windows 8.1 This box was designed to be beast, and until just recently, was very good at being just that. What's Happening The system has slowed to a crawl whenever it touches the disk. Things appear to work at normal speed when dealing with memory. For example, typing this is fine, but saving it to disk from notepad gave me a 5-7 second pause when clicking save. The disks appear to be at 100% all the time (e.g. the light on the disk access on the PC is solidly on -- not even any flashing) In ProcExp it appears that the disk is barely being utilized at all: Intel RST reports that everything is fine: Other Details Prior to this happening, RST had reported that my drives were failing (one went bad, one was throwing SMART events). This made sense; they were at the tail end of their warranty and the PC is on almost all the time. I RMA'd the drives via Seagate. In the meantime, I'd purchased a 2TB drive because I didn't realize that the 1TB drives were under warranty. I figured I'd replace the other 1 TB drive with another 2 TB when it died but then discovered the warranty. AFAIK, I haven't done any major updates since 8.1 and it worked fine after those. Question(s) How can I troubleshoot this? What is the best way to try to figure out why disks are being maxed out despite the OS reporting barely any disk usage and that everything is OK? Given the failures, etc. that I describe above, is it possible that the problem could be the I/O on the motherboard itself? If so, how would I even be able to diagnose it? I'm betting the drives that Seagate gave me are refurbished (didn't think to look; that's dumb). Is it possible that the same model drive, refurbished, could somehow cause this? In terms of how RAID1 works, is it possible that one drive is "falling behind" somehow, and that the RAID1 is constantly trying to fix the mirroring? If so, this seems like Intel RST would report on it, but I wanted to consider it as an option.

• Encrypted off-site data storage

  - by Dan

  My business has a rather unique problem. We work in China and we want to implement a file server paradigm which does not store any files locally, but rather in a server overseas. Applications would be saved onto our local machines, but data would be loaded directly into memory from the cloud, e.g. I load a docx into word at the beginning of the day, saving periodically to the cloud as I work on it, and turn off my computer at night, with nothing saved locally. Considering recent events, we worry about being raided by the Chinese authorities, and although all our data is encrypted, it would not be hard for the authorities to force us to give up the keys. So the goal is not to have anything compromising physically in China. We have about 20 computers, and we need an authenticated, encrypted connection with this overseas file server. A system with Active-Directory-like permissions would be best, so that only management can read or write to certain files, or workers can only access files that relate to their projects, and to which all access can be cut off should the need arise. The file server itself would also need to be encrypted. And for convenience, it would be nice if this system was integrated with each computer's file explorer (like skydrive or dropbox does, but, again, without saving a copy locally), rather than through a browser. I can't find any solution online. Does anyone know of a service that does this? Otherwise I'll have to do it myself (which kinda sounds fun, but I don't really have the time), and I'm not sure where to start. Amazon maybe. But the protocols that offices would use on their intranet typically aren't encrypted; we need all traffic securely tunneled out of the country. Each computer already has a VPN to a server in California, but I'm unsure whether it would be efficient to pipe file transfers through it. Let me know if anyone has any ideas. And this is my first post; feel free say whether this question is inappropriate/needs to be posted elsewhere.

• Use launchctl to fire an AppleScript script periodically

  - by Daktari

  I have written an AppleScript that lets me back up a particular file. The script runs fine inside AppleScript Editor: it does what it's supposed to do perfectly. So far so good. Now I'd like to run this script at timed intervals. So I use launchctl & .plist to make this happen. That's where the trouble starts. the script is loaded at set interval by launchctl the AppleScript Editor (when open) brings its window (with that script) to the foreground but no code is executed when AppleScript Editor is not running, nothing seems to be happening at all Any ideas as to why this is not working? -- After editing (as per Daniel Beck's suggestions) my plist now looks like: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <false/> <key>Label</key> <string>com.opera.autosave</string> <key>ProgramArguments</key> <array> <string>osascript</string> <string>/Users/user_name/Library/Scripts/opera_autosave_bak.scpt</string> </array> <key>StartInterval</key> <integer>30</integer> </dict> </plist> and the AppleScript I'm trying to run: on appIsRunning(appName) tell application "System Events" to (name of processes) contains appName end appIsRunning --only run this script when Opera is running if appIsRunning("Opera") then set base_path to "user_name:Library:Preferences:Opera Preferences:sessions:" set autosave_file to "test.txt" set autosave_file_old to "test_old.txt" set autosave_file_older to "test_older.txt" set autosave_file_oldest to "test_oldest.txt" set autosave_path to base_path & autosave_file set autosave_path_old to base_path & autosave_file_old set autosave_path_older to base_path & autosave_file_older set autosave_path_oldest to base_path & autosave_file_oldest set copied_file to "test copy.txt" set copied_path to base_path & copied_file tell application "Finder" duplicate file autosave_path delete file autosave_path_oldest set name of file autosave_path_older to autosave_file_oldest set name of file autosave_path_old to autosave_file_older set name of file copied_path to autosave_file_old end tell end if

• GPO Software Uninstall Not Taking Place

  - by burmat

  I am having some trouble with my software GPO's and can't seem to find any answers using Google. I successfully deployed software using my policy but when I delete another, the uninstallation of the software does not take place. What I did: Deployed software using a GPO, used gpupdate /force on the workstation to update, reboot, and install the software Deleted another software installation by: Right-Click All Tasks Remove 'Immediately uninstall the software from users and computers' From there, I did another gpupdate /force to try and get the GPO to refresh and uninstall the software on the workstation. This did not work. I then forced replication between my domain controllers and ran another gpupdate /force on the workstation and this did not uninstall the software. There are not error logs or indications that the uninstall is being triggered when I go into the event viewer, and I know for a fact that the policy is working in other aspects. So my questions is: Where do I look next to find the answer as to why GPO software deployments are working but un-installations are not, based off of what I have already tried? Thank you in advance. UPDATE: After using gpresult /z, there is no indication of a pending un-installation or removal of software. Under the section entitled "Software Installations", the software I am trying to uninstall is not listed. There is no other indication that the software I am trying to uninstall even exists. I also turned on RSoP logging and did (yet another) gpupdate /force to yield no blatant results. There is no indication that an uninstall event was even triggered, let alone incapability or failure. Although I am sure I marked it to uninstall in case of two events (the falling out of the scope of management, as well as the removal of the entry), I am beginning to think the entry just never triggered something that should have been triggered. UPDATE #2: After troubleshooting this (frustrating) application assignment, I have chalked it up as a fluke. I have tested with other software to make sure that the uninstall of other application assignments is actually working, so I am assuming it is something related to the package directly. There is the possibility that my problem resides in something related to what @joeqwerty linked in a comment below but because I can't go back in time, I don't think I will be able to prove it. I will probably be running a script via another GPO to guarantee the un-installation of left over package installs. For now, Evan Anderson is getting the answer because of the debugging information I was able to put to good use. Thank you to everyone that helped contribute so far!

• Yet again: "This device can perform faster" (Samsung Galaxy Tab 2)

  - by Mike C

  I've been doing a lot of research with no reasonable solution. Please excuse the length of my post. When I plug my Galaxy Tab 2 (7" / Wi-Fi only / Android ICS) into my Windows 7 64-bit machine, I (almost always) get this warning popup that "This device can perform faster." And in fact, transfers onto the Tab in this mode are slow. The two times I've been able to get a high-speed connection, the transfer has occurred at the expected speed. I just don't know what to do to get that high-speed transfer. (The first time I did, it was the first time I connected the Tab; the second time I did, I was fiddling around and unplugging/plugging in again.) That popup is telling me that the device is USB2, but that it thinks I've connected to a USB1 port. In fact, every USB port (there are ten) on this system is USB2. It's an ASUS M3A78-EMH mobo from late 2008. I'm not sure what the chipset is; the CPU is an AMD Athlon 4850e, but I've seen this message reported for non-AMD systems. (Every mobo reference I've seen in reports on this has been for Asus, but of course most reporters aren't reporting that info at all.) The Windows 7 installation is just a couple weeks old (I had a disk crash) but I saw the same warning on the WinXP/64 that was installed previously. In Device Manager, there are two "Standard Enhanced PCI to USB Host Controller" nodes which are the actual high-speed controllers. There are also five "Standard OpenHCD USB Host Controller" nodes, which I have determined are virtual USB1 controllers embedded in the "Enhanced" controllers. (In Device Manager, I'm using View|Devices by Connection.) My high-speed thumb drives, external disks, and iPod all show up as subnodes of the "Enhanced" controllers; the keyboard, mouse, and USB speakers under the "OpenHCD" ones -- and this is true no matter which ports these devices are plugged into. The Tab shows up under an OpenHCD node, unsurprisingly. It appears as a threesome: a top-level "Mobile USB Composite device" with two subs: "Galaxy Tab 2" and "Mobile USB Modem." (I have no idea what the modem device implies or how I might use it, but I don't care about it either: I just want the Tab to reliably connect at high speed.) On the Tab, the USB support has a switch between PTP and MTP, the latter being the default, and the preferred mode for me (as I'm usually hooking it up for music synch). I have tried, however, connecting it as PTP, and it still connects as USB 1. (As PTP, only the "Galaxy Tab 2" device appears -- no Composite, no Modem.) If it's plugged in as MTP and I change the setting to PTP, Windows unloads and reloads the device, and voila: The Tab appears under an "Enhanced" node, but eventually re-loads again to show a exclamation icon on the device; Properties then shows "This device cannot start." Same response if I plug it in as PTP and then change to MTP; in this case, only the Tab itself shows the exclamation, not the other two devices. One thing I have not tried, and really would prefer to avoid, is installing the "beta" chipset driver available on the Asus website, which is dated 2009. Windows tells me it has the most up-to-date drivers for the Tab, and for the chipset, and I'm inclined to believe that. I suspect the problem is with the Samsung drivers, or possibly the hardware. One suggestion I saw elsewhere which might, possibly, pertain is to ensure the USB cable is properly shielded; however, the Tab has one of those misbegotten 30-pin, not-quite-an-iPod connectors; I don't know if I could find a 3rd party one. It seems unlikely that this cable is improperly shielded, tho. (Is there a way to test that?) So, my question is: does anyone know how to get this working as one might reasonably expect it to?

• nginx, php-cgi and "No input file specified."

  - by Stephen Belanger

  I'm trying to get nginx to play nice with php-cgi, but it's not quite working how I'd like. I'm using some set variables to allow for dynamic host names--basically anything.local. I know that stuff is working because I can access static files properly, however php files don't work. I get the standard "No input file specified." error which normally occurs when the file doesn't exist, but it definitely does exist and the path is correct because I can access the static files in the same path. It could possibly be a permissions thing, but I'm not sure how that could be an issue. I'm running this on Windows under my own user account, so I think it should have permission unless php-cgi is running under a different user without me telling it to. . Here's my config; worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; gzip on; server { # Listen for HTTP listen 80; # Match to local host names. server_name *.local; # We need to store a "cleaned" host. set $no_www $host; set $no_local $host; # Strip out www. if ($host ~* www\.(.*)) { set $no_www $1; rewrite ^(.*)$ $scheme://$no_www$1 permanent; } # Strip local for directory names. if ($no_www ~* (.*)\.local) { set $no_local $1; } # Define default path handler. location / { root ../Users/Stephen/Documents/Work/$no_local.com/hosts/main/docs; index index.php index.html index.htm; # Route non-existent paths through Kohana system router. try_files $uri $uri/ /index.php?kohana_uri=$request_uri; } # pass PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ { root ../Users/Stephen/Documents/Work/$no_local.com/hosts/main/docs; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; } # Prevent access to system files. location ~ /\. { return 404; } location ~* ^/(modules|application|system) { return 404; } } }

• Windows Server 2008 R2 time keeps changing unexpectedly

  - by lmhost

  There is a serious problem with one of my servers time. At some random hours (5:59 localtime in the following example) it goes 1 hour back and keeps doing this again and again next times it reaches 5:59. Like this: 5:59-4:59 … 5:59- 4:59 and so on. It stays in the loop until I manually update its time.

• Apache strace to hunt down a memory leak

  - by Zipp

  We have a server with a memory issue: the server keeps allocating itself memory and doesn't release it. We're running Apache. I set MaxReqsPerClient to a really low value just so the threads don't hold a lot of memory, but has anyone seen calls like this? Am I wrong in thinking that it's probably Drupal pulling too much data back from the cache in DB? read(52, "h_index\";a:2:{s:6:\"weight\";i:1;s"..., 6171) = 1368 read(52, "\";a:2:{s:6:\"author\";a:3:{s:5:\"la"..., 4803) = 1368 read(52, ":\"description\";s:19:\"Term name t"..., 3435) = 1368 read(52, "abel\";s:4:\"Name\";s:11:\"descripti"..., 2067) = 1368 read(52, "ions\";a:2:{s:4:\"form\";a:3:{s:4:\""..., 16384) = 708 brk(0x2ab554396000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f653000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f753000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f853000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f953000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55fa53000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55fb53000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55fc53000 poll([{fd=52, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout) write(52, "d\0\0\0\3SELECT cid, data, created, "..., 104) = 104 read(52, "\1\0\0\1\5E\0\0\2\3def\23drupal_database_nam"..., 16384) = 1368 read(52, ";s:11:\"granularity\";a:5:{s:4:\"ye"..., 34783) = 1368 read(52, ":4:\"date\";}s:9:\"datestamp\";a:9:{"..., 33415) = 1368 read(52, "\";i:0;s:15:\"display_default\";i:0"..., 32047) = 1368 read(52, "e as an integer value.\";s:8:\"set"..., 30679) = 1368 read(52, "label' pairs, i.e. 'Fraction': 0"..., 29311) = 1368 top (the procs just keep growing in memory..): 12845 apache 15 0 581m 246m 37m S 0.0 4.1 0:17.39 httpd 12846 apache 15 0 571m 235m 37m S 0.0 4.0 0:12.13 httpd 12833 apache 15 0 420m 117m 37m S 0.0 2.0 0:06.04 httpd 12851 apache 15 0 412m 113m 37m S 0.0 1.9 0:05.32 httpd 13871 apache 15 0 409m 109m 37m S 0.0 1.8 0:04.90 httpd 12844 apache 15 0 407m 108m 37m S 0.0 1.8 0:04.50 httpd 13870 apache 15 0 407m 108m 37m S 0.3 1.8 0:03.50 httpd 14903 apache 15 0 402m 103m 37m S 0.3 1.7 0:01.29 httpd 14850 apache 15 0 397m 100m 37m S 0.0 1.7 0:02.08 httpd 14907 apache 15 0 390m 93m 36m S 0.0 1.6 0:01.32 httpd 13872 apache 15 0 386m 91m 37m S 0.0 1.5 0:03.13 httpd 12843 apache 15 0 373m 81m 37m S 0.0 1.4 0:02.51 httpd 14901 apache 15 0 370m 75m 33m S 0.0 1.3 0:00.78 httpd 14904 apache 15 0 335m 29m 15m S 0.0 0.5 0:00.26 httpd

• Small Business Server services will not start, and remote desktop and UAC are broken

  - by Stephen Jennings

  Yesterday I began setting up a server with Windows Small Business Server 2008. All I am configuring it for right now is to be a domain controller and Exchange server. I completed the initial setup of SBS then started looking through different connection options (allowing VPN versus using a TS Gateway). After I rebooted one time, I started having three not-obviously-related issues: First, I could no longer remote desktop into the computer. I ran TCPView and saw that it was no longer listening on port 3389. I checked everything in Terminal Service Configuration but everything shows the computer ought to be allowing connections. Also, when I tried to use anything that required user account control elevation, the UAC dialog never popped up and the program that was waiting just froze. If I try to run "regedit" from the Run box, for example, it never appears. When I run in safe mode which does not run with UAC, I was able to access everything. I didn't want to deal with it, so I turned off UAC and rebooted. Finally, in the Windows SBS Console, there are status indicators for Security, Updates, Backup, and Other Alerts. The first three get stuck saying "Querying". Looking in the computer alerts, I have events showing the following services stopped: Background Intelligent Transfer Service KtmRm for Distributed Transaction Coordinator Distributed Transaction Coordinator Microsoft Exchange Information Store Microsoft Exchange System Attendant Microsoft Exchange Transport Windows Remote Management Update Services Windows Update I figured I must have configured something wrong accidentally and I couldn't find anything using Google explaining what might be the case, so I just decided to format the hard drive and reinstall SBS from scratch. I did this and everything was working last night, but I just turned the machine back on and it is doing the same thing again! On my second install, I did not configure anything except the following (all from SBS Console): Connect to the Internet (set IP and router address) Turn off customer feedback. Set up internet address. Decline to use a Smart Host for email. Added one standard user account. Since this happened again and I was very careful the second time not to configure anything outside of the SBS Console, I feel like there's something else going on. Right now the machine is on an isolated network that does have internet access. My desktop is the only other machine plugged into this network. Any and all help is appreciated (before I tear my hair out!)

• nginx connection time issue on some IPs

  - by sheldon

  I have recently shifted my server to nginx and php-fpm getting rid of apache. This has helped improves speeds of my website. Everything seems to work fine until i came across this issue, i noticed that nginx keeps throwing connection time out errors for only certain IPs. One of the IPs is my office IP, we have a backend that is accessed from our office through out the day. I use supervisord to launch 3 php-fpm processes with workers this is my typical php-fpm config pm.max_children = 50 pm.start_servers = 20 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 300 Since i have a server with 4 cores and 2 GB ram this is my nginx setup worker_processes 4; worker_rlimit_nofile 8192; events { worker_connections 1024; use epoll; multi_accept off; } sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 55; recursive_error_pages on; server_name_in_redirect off; server_tokens off; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; connection_pool_size 256; client_header_buffer_size 8k; large_client_header_buffers 4 32k; request_pool_size 4k; output_buffers 4 32k; postpone_output 1460; proxy_buffer_size 32k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; fastcgi_connect_timeout 120; fastcgi_send_timeout 120; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_ignore_client_abort off; Where am i going wrong with the config, I have tried various settings but the issue still persists.

• Setting up nginx as proxy to apache; All good, but nginx doesn't serve media

  - by becomingGuru

  I have set it up such that nginx proxies request and sends django requests to apache and serves media itself. Following documents my setup: Nginx Configuration: /etc/nginx/nginx.conf user www-data; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; include /etc/nginx/sites-enabled/*; } ===== ngnix proxy /etc/nginx/proxy.conf ============ proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; =========== Nginx server file: /etc/nginx/sites-enabled/some-name.txt ========== server { listen 208.109.252.110:80; server_name netconf; autoindex on; access_log /home/site/server_logs/nginx_access.log; error_log /home/site/server_logs/nginx_error.log; location / { proxy_pass http://127.0.0.1:80/; include /etc/nginx/proxy.conf; } location /site_media/ { root /home/site/folder/static; } } ========== Nginx very well proxies the request and passes to apache, the required requests, but doesn't serve the media. In the last server file, location site_media is not served, at all. :( Everything seems perfect to me. What is wrong? Thanks in advance.

• ubuntu 10.04; kvm bridged networking not working with public ip addresses

  - by senorsmile

  I have a dedicated hosted server box with ubuntu 10.04 64 bit installed. I would like to run kvm with ubuntu 8.04 installed for some php 5.2 compatible apps(they don't work right with php 5.3, the default in ubuntu 10.04). I installed KVM as instructed at https://help.ubuntu.com/community/KVM/Installation . I installed the vm using virt-manager. I never could figure out how use virt-install or any of those automated installers. I just installed it using the disc. I set up bridged networking as per https://help.ubuntu.com/community/KVM/Networking . However, the bridged connection doesn't work. Here's my /etc/network/interfaces on the host, running ubuntu 10.04. (with specific public ip blanked) auto lo iface lo inet loopback auto eth0 iface eth0 inet manual auto br0 iface br0 inet static address xx.xx.xx.xx netmask 255.255.255.248 gateway xx.xx.xx.xa bridge_ports eth0 bridge_stp on bridge_fd 0 bridge_maxwait 10 ` Here's my /etc/network/interfaces on the guest, running ubuntu 8.04. auto lo iface lo inet loopback auto eth0 iface eth0 inet static address xx.xx.xx.xy netmask 255.255.255.248 gateway xx.xx.xx.xa The two vm's can communicate to each other. But, the guest vm can't access anyone in the real world.

• Why does Ubuntu 9.10 hang during boot at "Booting processor 1 APIC 0x1 ip 0x6000"?

  - by BraeburnDev

  I recently installed a new copy of Ubuntu 9.10 (Kernel 2.6.31-14) on to my Hp Pavilion dv6t, so I can setup a Linux development environment. The install went flawlessly and I proceeded with Ubuntu's udate manager's long list of updates (292 in all). I also setup a swap file and activated a Nvidia 185 driver for the Nvidia 260m GPU on the machine. After all this was done I restarted the computer and booted into Ubuntu this time with a newer 2.6.31-19 Kernel which was installed from the update manager. During booth the computer hung at this point: Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013136] Performance Counters: Nehalem/Corei7 events, Intel PMU driver. Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013141] ... version: 3 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013142] ... bit width: 48 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013144] ... generic counters: 4 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013146] ... value mask: 0000ffffffffffff Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013147] ... max period: 000000007fffffff Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013149] ... fixed-purpose counters: 3 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013151] ... counter mask: 000000070000000f Feb 24 14:23:12 braeburn-laptop kernel: [ 0.015539] ACPI: Core revision 20090521 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.052264] Setting APIC routing to flat Feb 24 14:23:12 braeburn-laptop kernel: [ 0.052639] ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.152580] CPU0: Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz stepping 05 Feb 24 14:23:12 braeburn-laptop kernel: [ 0.270845] Booting processor 1 APIC 0x1 ip 0x6000 I can post a full kern.log of this boot process if requested. Hopefully this is enough information to go on. I should add that I'm still new to configuring and running a Linux OS although I know enough basic command line usage to do software development. This is my attempt to become more familiar with Linux and manage my own system. I'd like to get some insight on the nature of this system hang, what the problem is and how to resolve it. At this point I can scrap the install if I broke something, but my intuition says this is an issue with the kernel recognizing the correct hardware configuration for my system, or perhaps this is an issue with the APIC drivers managing Nehalem's new power management capabilities? Thanks for looking at this issue and providing feed back.

• External USB HD issues with a twist (works on Windows7 but not XP)

  - by Eruditass

  I have this older external USB HD, 160 GB. I was using it to copy my Steam games to another computer. On the source computer, Windows 7 64-bit, everything worked fine. Drive reported no errors, had no hiccups, etc. Plugging it into the Windows XP 32-bit computer, it worked fine for looking through the files, moving files around on it (no real reading/writing, just modifying the filesystem table). However, when copying files from it to my internal HD, after a couple seconds to tens of minutes (seemingly random times), the USB device becomes unrecognized and it reports a delayed write error. Events in system log go like this, chronologically: (number times displayed)xSource (Event ID): "message" 2xdisk (51): An error was detected on device \Device\Harddisk1\D during a paging operation. 1xftdisk (57): The system failed to flush data to the transaction log. Corruption may occur. 1xApplication popup (26): Windows - Delayed Write Failed : Windows was unable to save all the data for the file E:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. 1xntfs (50): {Delayed Write Failed} Windows was unable to save all the data for the file . The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. These repeat for a while, then there is 10+ disk messages or ftdisk messages. Other notes: This occurs on random files at random times. This problem cannot be replicated on the Windows 7 source machine when copying from the HD to a different location on its local disk chkdsk /f was run and found no errors. chkdsk /f/r has the delayed write issue. drive was set to quick removal. Setting to performance in device manager yielded same result I am not writing anything to the USB external drive, so I am not sure why there is even a delayed write error (writing file access times?) local Windows XP was chkdsk'd without problems Windows XP machine has no problems with other USB HD's Various USB ports were attempted Rebooting did not help Occurs with SyncToy as well as windows explorer SMART status is good on both local drive and the external one Lack of gaming is making me cranky

• Windows 7 sometimes boots in VGA mode

  - by TuxRug

  I have an Asus G50VT-x5 laptop with nVidia GeForce9800M-GS graphics. Normally, Windows boots normally, but about 20% of the time (rough estimate), it will boot with the fallback VGA driver, maxing out at 800x600 with no Aero. I've checked the system logs and there is nothing indicating an error loading the nVidia driver. It even specifies in the logs that the Nvidia Display Driver service started successfully, even though it has booted in safe graphics mode. This has been happening for a while, but it's happening a little more often now than it was before. Since the first time my system exhibited this behavior, I have updated my graphics driver a handful of times. I used System Information for Windows to check for problems there, but the only thing that stood out was the following: Core Temperature 4486449 °C (8075639 °F) Shaders Temperature 1171513530 °C (2108724330 °F) I know this reading is incorrect, because my laptop is nowhere near the surface of the sun and my desk has not burst into flames. When it's opererating normally, I get a sane reading like [Core Temperature 58 °C (136 °F)] with no Shaders Temperature listed. All I have to do to resolve the issue is reboot. I have seen no stability issues with the graphics or anything else. A long time ago, I had an issue with this computer where my framerate would suddenly drop during a 3D game from 40fps to <1fps, but after looking at the temperature readout immediately after quitting a game, I removed the bottom panel and blew the dust out of the vent and heatsink. Since then I have no drops in framerate under any situation. I have uploaded a zip containing the SIW reports for when the problem is occurring and when the computer is operating normally. I don't have a paid account so it can only be downloaded 10 times, so please only download the reports if you think you can use them. If you try to download the reports and they are no longer available, please comment and I will re-upload them. If you want to look at the files, they are on Rapidshare. EDIT It happened again, and I looked a little deeper into the System logs. When this happens, there are a lot of errors about other device drivers unable to start. All of these errors are for PnP drivers. Also, my USB keyboard and mouse take a few moments before they actually start working, although this happens sometimes the first normal boot as well. I am quite sure this is related, so I am adding the pnp tag. Also, CHKDSK will not run on boot. Even if a check is scheduled or a volume is manually set as dirty, CHKDSK will be skipped entirely, not even leaving an entry in the System logs. I tried running CHKNTFS /D, which did not work. I then manually changed my HKLM\System\CurrentControlSet\Control\Session Manager BootExecute value to the default listed on Microsoft's website. That did not work either. I ended up booting to repair mode and running CHKDSK there, which found a number of minor inconsistencies on my system drive, but none on my data drive. I have no idea if this is related. Some more information for those who don't download my SIW report file: Antivirus and Firewall are ESET Smart Security I have three different virutalization programs installed: VMware Player, Windows Virtual PC, and VirtualBox. The network adapters for these show up in the log of failed device starts. EDIT 2 I tried running sfc /scannow, which reported that it found corrupted files that could not be fixed. The CBS log is extremely cryptic. I tried booting to my install disk, launching repair mode, and doing an offline sfc from there, which produced the same result.
