• Xen dom0 reports incorrect amount of RAM with dom0_mem set

  - by xen_amnesiac

  I've done a fair bit of searching about this, but have found nothing that answers my question. I have a system with 6GB of RAM which acts as a Xen server. For reference, it runs Ubuntu 12.04. I've set the kernel parameter dom0_mem:512M,max:512M in /etc/default/grub as follows: GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=min:512M,max:512M" I've tried variations of that, with the same result. My question is this: With the above set, the dom0 reports in all applications a RAM amount of 422M. cat /proc/meminfo gives the following: $ cat /proc/meminfo MemTotal: 432472 kB MemFree: 54144 kB Buffers: 17640 kB Cached: 220104 kB SwapCached: 30172 kB Active: 136500 kB Inactive: 167780 kB Active(anon): 6156 kB Inactive(anon): 60516 kB Active(file): 130344 kB Inactive(file): 107264 kB Unevictable: 52 kB Mlocked: 52 kB SwapTotal: 1794044 kB SwapFree: 1682012 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 39572 kB Mapped: 8048 kB Shmem: 136 kB Slab: 44324 kB SReclaimable: 22012 kB SUnreclaim: 22312 kB KernelStack: 1280 kB PageTables: 3840 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 2010280 kB Committed_AS: 329192 kB VmallocTotal: 34359738367 kB VmallocUsed: 313988 kB VmallocChunk: 34359417340 kB HardwareCorrupted: 0 kB AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 524696 kB DirectMap2M: 0 kB top, htop, free -m, and byobu's RAM monitor all report the same amount. At first I thought this was because of the onboard graphics borrowing some memory, but have now switched to a dedicated GPU and it persists. Is this normal behavior, or has something gone amiss? It's just about 100MB of RAM that's "gone", and I have no idea where it went. I understand that it's normal that not all RAM is available for allocation, but does the system really take an amount relatively high to the amount of RAM available?

• How can I manually install pecl_http on Ubuntu 9.10?

  - by Richard

  This is essentially a repost of http://stackoverflow.com/questions/4159369/ubuntu-9-04-pecl-extension-downloads-but-does-not-install. Hoping maybe someone can help me here. I've done this: sudo apt-get install php-pear sudo apt-get install php5-dev sudo apt-get install libcurl3-openssl-dev which installs fine. However, the next step: sudo pecl install pecl_http Doesn't install the extension, but merely downloads it. There are no error messages. So I have unpacked it and built it myself per http://php.net/manual/en/install.pecl.phpize.php Essentially: cd pecl_http phpize ./configure make make install I also make test'd to check all ok - and it failed one test: HttpRequest, which is kind of fundamental to this package. And indeed this doesn't work: $r = new HttpRequest('http://www.google.com'); $r->send; echo $r->getResponseCode(); No request is sent, the response code is zero, but no errors either. How can I get this damn thing installed? Is this a bug? Am I doing something wrong? Any alternatives, workarounds? Help appreciated. Thanks

• Migrate Windows Server 2008 to a new hard disk 2

  - by MainMa

  Hi, A few weeks ago, I already asked how to move a Windows Server 2008 to a new hard disk. Despite the previous answers and two weeks lost trying to do it, I am always unable to move the OS to the new drive. What I tried: A backup/restore using Windows Backup. This never helped. First, I tried to backup, then copy the backup to a new drive, then restore. This results in "The parameter is incorrect. (0x80070057)" error caused by a bug in Windows Backup. Recently, I attempted to backup to a network share, but I can't restore from it, because of a "*The network path was not found. (0x80070035)" error. Trying the netsh interface ipv4 set address [...] does not work neither (saw at least three different errors, mostly "The interface is unknown.") A previously suggested solution using imagex from Windows AIK results in a non-bootable disk after writing an image to it. When booting from Windows 2008 installation disk (from USB), it finds that the HDD is not bootable and proposes to fix this, but then crashes, resulting in an unbootable USB flash disk (and HDD stays unbootable). As I said in my previous question, doing a clone of a hard disk drive gives an (of course) bootable disk, but Windows complain about hardware changes and cannot start. Now can somebody suggest me another way to move Windows Server 2008 to a new hard disk? Is it at least possible to do, or any hard disk failure/change implements necessarily to reinstall the whole OS?

• Application losing Printer within Terminal Services for remote users

  - by Richard

  Question: What I need to do is have a permanent link to a printer, normally only accessible through Terminal Services (Printer Redirect), to allow Sage Line 50 layouts to see that printer persistently, even after users have disconnected and reconnected to the Terminal Services session? Although the printer is accessible each time a user connects to the Sage Server via Terminal Services, it is given a different session number and therefore the Sage Layout sees it as a different printer. History behind question: Users using Terminal Services connecting to a Sage Server on a different site Using Sage Line 50 v 15 on that Server Users want to print invoices (sage layouts) locally Sage Server cannot see the users local printers, to get around this user uses the Print redirect features of Terminal Services The individual reports can be edited to point to a specific printer by default. This means the user just has to select an invoice and click print, then select the layout/report wanted and it auto prints that invoice to the default printer specified. The problem occurs because the layouts are edited to point to the users local printer "Ricoh 1018d (session#)", note the "(session#)" as this is the users local printer being redirected through the terminal services session. Users are able to print using the sage layouts once the default printer is setup within the layout and saved, but as soon as the users disconnects from the Terminal Services session and then reconnect in the morning go to print, it has lost the connection to that printer. I understand why its failed, because that the printer is on a per session basis and the layout would not be able to hold on to the connection from a previous session. Thanks in advance for any assistance...

• external drive enclosure -> software RAID 5?

  - by memilanuk

  Hello all, I have two older PCs on my LAN posing as 'servers'... one running FreeNAS off a USB stick using three 500GB hdds in a ZFS RAID-Z pool serving as storage for the LAN and one running Debian Lenny with an 80GB drive used as a general purpose 'tinker' box that I can ssh into, etc. Problem is that the SMART report for one of those 500GB drives in the FreeNAS box is showing some pre-failure attributes, and the whole array is a little small anyways. Rather than simply replace one 500GB drive with another 500GB drive, and have no backup of the file server, I'd like to upgrade all the drives to 2TB ones - but I have no where to store that much data in the mean while. As such, I started looking at getting a 4-bay external drive enclosure with an eSATA card for the Debian box, with the hopes of creating a RAID5 + LVM setup using those drives and backing the data up to that external drive enclosure. After the backup is done, replace the drives in the FreeNAS box and rebuild the array there and mirror the data back. Then, I'd have both the primary storage (on the FreeNAS box) and a backup (which I don't have currently) using the external drive enclosure on the Debian box. My big question is... most of these external drive boxes seem to claim support for JBOD, RAID 0, 1, 10, 5, etc. - should I presume that is simply fake RAID like many commodity mobos have, and not really usable in Linux? In that case, with all the drives hanging off the one eSATA connection, will Linux (specifically Debian Squeeze, as I plan on upgrading that box here shortly) see all four drives, or just the first one? Will I be able to configure them in a RAID5 array as desired? Thanks, Monte

• How to multiseat with HW 3d accel on CentOS 6.3 Final?

  - by user35070

  I would like to setup a multiseat configuration on CentOS 6.3 (two video cards, two keyboards, two mice, two monitors) and have hardware accelerated 3D on both monitors. 3D HW acceleration rules out Xephyr. I saw somewhere that recent versions of GDM (3.3 and newer?) don't support multiseat, so do I have to install KDM to make this work? If I just create a duplicate section with new device identifiers in my xorg.conf file, will this 'just work'? Using different ports on the same video card and separate keyboards, mice, and displays, the result was a desktop which spanned both monitors with both keyboards and mice acting as the same input in the GUI. I will power down and put in the new video card and report on the results soon. Both video cards are nvidia. UPDATE after putting in another NVIDIA video card, default behavior (before changing xorg.conf) is that one screen works normally, and both mice and keyboards are connected to it. Changing xorg.conf and the display manager to KDM and following the directions here https://help.ubuntu.com/community/MultiseatX#Ubuntu_10.04_.28Lucid.29 , I have 2 mirrored screens connected to separate video cards, DRI enabled, and 2 mice both connected to the same pointer. Keyboards don't do anything, however, I probably just need to fix a setting in xorg.conf I would still like to get multiseat functionality, eg. separate screens with separate input devices I have verified that the separate X processes are running (see page above) using 'ps aux | grepX [01]'

• Task Scheduler Crashing MMC

  - by Valrok

  I've been getting errors whenever I try to run the task scheduler for Windows 2008 R2. Each time that I've tried running it, the task scheduler will crash and report the following: Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: mmc.exe Problem Signature 02: 6.1.7600.16385 Problem Signature 03: 4a5bc808 Problem Signature 04: System.Windows.Forms Problem Signature 05: 2.0.0.0 Problem Signature 06: 50c29e85 Problem Signature 07: 151f Problem Signature 08: 18 Problem Signature 09: Exception OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1033 I've been looking online but so far I keep finding mixed results on what could be the fix for this and was wondering if anyone here has ever ran into this issue before. I read that this issue could be because of Security Update for Microsoft Windows (KB2449742) and that by uninstalling it I would be able to fix this issue, however I was not able to locate this anywhere in the server. Here's the link if interested Patch wise, everything is up to date. Also, I tried running hotfix KB2688730 to see if that would work after doing some research online, however the hotfix is not applicable to the computer. If anyone could provide some information on how to fix this and get the task scheduler running again it would be extremely helpful!

• Unable to connect remotely to Vsftpd server set up on CentOS VirtualBox

  - by ryekayo

  I have set up a Vsftp server using the following instructions provided Here and even went as far as following the commentary at the bottom. But I am unable to connect remotely. When I attempt to use FileZilla or my Ubuntu terminal, I always get: ryan@ryan-Galago-UltraPro:~$ ftp 10.0.x.xx ftp: connect: Connection timed out ftp> I have checked and re-checked iptables conf file and made sure that Port 21 is being Accepted and it is. I have looked this up on the web and decided to try nmap to port scan it and this is what I get for a result: ryan@ryan-Galago-UltraPro:~$ nmap -PN 10.0.xx.xx Starting Nmap 6.40 ( http://nmap.org ) at 2014-08-19 15:01 EDT Nmap scan report for 10.0.xx.xx Host is up. All 1000 scanned ports on 10.0.xx.xx are filtered Nmap done: 1 IP address (1 host up) scanned in 201.38 seconds Is there anything else that I should do or check for? UPDATE: I have tried to ping from the virtual machine to my IP address on Ubuntu and have been successfully able to. I cannot ping to my virtual machine from Ubuntu. I have narrowed this down to possibly being a firewall related issue on Ubuntu's side, but why would I be unable to connect from FileZilla?

• Nagios NTP, discarding peer

  - by picca

  We're using nagios *check_ntp_time* for monitoring time on our servers. Unfortunately the service is flapping. And reporting a lot of false-positives.

When the problem occurs we get: watch01:~ # /usr/lib/nagios/plugins/check_ntp_time -H lb01 -w 1 -c 2 -v sending request to peer 0 response from peer 0: offset 0.07509887218 sending request to peer 0 response from peer 0: offset 0.07508444786 sending request to peer 0 response from peer 0: offset 0.07499825954 sending request to peer 0 response from peer 0: offset 0.07510817051 discarding peer 0: stratum=0 overall average offset: 0 NTP CRITICAL: Offset unknown| When everything is ok, we get (I used different server to not have to wait): watch01:~ # /usr/lib/nagios/plugins/check_ntp_time -H web02 -w 1 -c 2 -v sending request to peer 0 response from peer 0: offset 0.0002282857895 sending request to peer 0 response from peer 0: offset 0.0002194643021 sending request to peer 0 response from peer 0: offset 0.0002347230911 sending request to peer 0 response from peer 0: offset 0.0002293586731 overall average offset: 0.0002282857895 NTP OK: Offset 0.0002282857895 secs|offset=0.000228s;1.000000;2.000000; We are using: check_ntp_time v1.4.15 (nagios-plugins 1.4.15) on Debian squeeze. Remote ntp daemon is: ntpd - NTP daemon program - Ver. 4.2.4p4 I already found some forums where the problem is described: 1, 2, 3. Every time they edvise to upgrade nagios-plugins, because in version prior to 1.4.13 there was a bug with inserted leap second. But we have already newer version of nagios-plugins.

• Mysql Fail to start

• puppet master --compile logs errors to stdout

  - by danny

  I see a bug about this that was accepted and then closed a year ago: http://projects.puppetlabs.com/issues/3670 but I'm using puppet 2.7.14 and am getting the same issue. I'm trying to use "puppet solo" (i.e. just running puppet apply on each server to be configured) as I only have 2 or 3 servers in this project and adding another server as a puppetmaster would be completely overkill. Unless I'm mistaken, the best way to apply a node manually to a server is to do: puppet master --compile=mynode > catalog.json puppet apply --catalog catalog.json But the puppet master command outputs a couple of warnings and notices to stdout, mixed in with the desired json content. And it uses colored output so I can't just pipe it through egrep -v '^warning:' EDIT: I guess it's not too big of a deal to use grep - since puppet 2.7 pretty-prints the actual content and the warnings don't ever start with spaces, piping the output through egrep '^( |{|})' works So my questions are basically: Is there a better way than this to apply a puppet node without using a puppetmaster? I can't really find any good references online to using puppet without a puppetmaster, even though that seems like a perfectly reasonable thing to do for a small project. Is there a setting or flag that I'm missing that will get puppet master to stop being an asshole and send its errors to stderr instead of stdout? Or do I really have to turn off color logging, then grep to exclude warning: and notice: lines?

• Windows 7 Apache Crashes on ANY request

• Random Hard Freeze of Windows 7 (is Kaspersky to be blamed for this?)

  - by Christian Ivicevic

  The last few weeks I experienced a new strange behavior of my computer. Sometimes Windows 7 just freezes with no real reason at all. While listening to music for example the playback hangs and you can hear a very nasty sound. Neither mouse nor keyboard input is handled and everything is just stuck. Using Ubuntu this does not happen, so I think it is just a matter of driver issues or a Windows 7 bug. Furthermore I am really suspicious about Kaspersky (Internet Security 11) and so I let it perform a complete virus scan while no other app is running. At about 50% it happened again and I needed to restart the computer by holding the power button the bad way... A really weird thing is that playing Skyrim this happened once, however music playback did not stop. Only the framerate dropped to 0 and sometimes for a few seconds I am able to move. Therefore I am really confused as furthermore no bluescreen pops up. Memtest told me that everything seems to be alright... Can anyone explain me which data you need about my hardware and software (and which tools tools to use to gather the informatik) to be able to provide any help on my problem?

• Weird .#filename files on remote ssh-connected systems after mcedit

  - by etranger

  I'm using MacFusion sshfs in combination with Midnight Commander, and when I edit remote text files with mcedit, weird symlinks are created on the remote system. $ ls -l .* lrwxr-xr-x 1 user group 34 Jun 27 01:54 .#filename.txt -> [email protected] where etranger is my local login name, and mbp is a hostname of my notebook running MacOS. symlinks can be removed by running remote rm command, but cannot be deleted on the mac-fuse mounted volume and thus pollutes the filesystem. I cannot figure what part of software is responsible for this, and how I could fix this, any help is appreciated. EDIT: This appears to be mcedit behavior as documented here: https://dev.openwrt.org/ticket/8245 Apparently, sshfs fails to remove symlink to the lock file for some reason (".#" in filename, perhaps), and it pollutes the filesystem. A quick workaround is possible, using another bug of Midnight Commander: editing (F4) the broken symlink effectively converts it to a missing lock file it was supposed to point to, and removes the symlink itself. The newly created file may then be deleted normally. EDIT 2: Unchecking "Follow symlink" in MacFusion apparently allows sshfs to remove dead symlinks, so the problem disappears completely.

• sorry, the maximum allowed clients from your host (10) are already connected" FTP error

  - by Sejanus

  Hello, I keep getting the "sorry, the maximum allowed clients from your host (10) are already connected" error whenever I try to transfer a large number of files. At first I thought it's a filezilla bug, however I get the same error basically with every FTP client I've tried, including Total Commander under Wine. I do not get that error using Windows. I did try to limit maximum allowed connections for Filezilla, both in server settings and in global settings, it didnt change anything. I did try to switch between passive and active modes (not sure if it's related at all, just last desperate attempt), and it didnt change anything either. When I try to use native ftp client (not sure how is it called, the one in Places - Connect to a server) I get abstract "connection refused" error every time I transfer large number of files. Connection is refused for separate particular files, if I click "Ignore" each time the rest of files are transfered perfectly well, so I assume it's the very same error. Anything I could do? This really drives me mad, transfering large numbers of files is a part of my everyday job... P.S. and this happens with many different FTP servers. Also I dont get this error in Windows. So I assume it's not a server problem. P.P.S. I am aware of similar question here, the answer provided just didn't solve it to me.

• win8: access denied to external USB disk; update access rights fails

  - by Gerard

  I use to work with 2 laptops (vista and win7), my work being files on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take win8. 1/ I suspect something changed with access rights, as my external disk suffered some "access denied" problem on win8. I was prompted (by win8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying "disk is not ready". Additonnally, the usb somehow was not recognized anymore. 2/ Back to win7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them i could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under win7, all the folder showed with a lock. 3/ Then back again to win8. Same problem : access denied to my disk + no way to change access rights as it gets stuck "disk is not ready". Now I am pretty sure there is some kind of bug or inconsistence in win8 / win7. I did 2/ and 3/ a few times. At some point, I also got an access denied in win7. I could restore access rigths to the disk to "system" (properties - security - EDIT for full control to group "system" ...). But then I still get the same access right pb on win8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. Now, after I tried for more than 3 days, I am losing my patience with that bloody win8 which I did not want to buy but had no choice. I upgraded win8 with the windows updates available. Does not help. Anybody can help me ?

• Running gdb on Ubuntu 9.10 Apache2 Install

  - by AJ

  Hi all, I am trying to run gdb to debug my Ubuntu 9.10 Apache2 install and having a couple of problems: It seems like the package installed by Ubuntu for Apache2 does not include debugging symbols; is there a different version of the package I should be using for developing/debugging? When I try to run gdb, I get an error that looks to be caused by some missing environment variable. Are there additional options I should pass to "run" to get this to work?

• Application losing Printer within Terminal Services for remote users

  - by Richard

  Question: What I need to do is have a permanent link to a printer, normally only accessible through Terminal Services (Printer Redirect), to allow Sage Line 50 layouts to see that printer persistently, even after users have disconnected and reconnected to the Terminal Services session? Although the printer is accessible each time a user connects to the Sage Server via Terminal Services, it is given a different session number and therefore the Sage Layout sees it as a different printer. History behind question: Users using Terminal Services connecting to a Sage Server on a different site Using Sage Line 50 v 15 on that Server Users want to print invoices (sage layouts) locally Sage Server cannot see the users local printers, to get around this user uses the Print redirect features of Terminal Services The individual reports can be edited to point to a specific printer by default. This means the user just has to select an invoice and click print, then select the layout/report wanted and it auto prints that invoice to the default printer specified. The problem occurs because the layouts are edited to point to the users local printer "Ricoh 1018d (session#)", note the "(session#)" as this is the users local printer being redirected through the terminal services session. Users are able to print using the sage layouts once the default printer is setup within the layout and saved, but as soon as the users disconnects from the Terminal Services session and then reconnect in the morning go to print, it has lost the connection to that printer. I understand why its failed, because that the printer is on a per session basis and the layout would not be able to hold on to the connection from a previous session. Thanks in advance for any assistance...

• Windows 8 auto-hibernate from sleep not working on Retina MacBook Pro

  - by frenchglen

  I have a similar question to this one. Only my context is the 15" Retina MacBook Pro - and Windows 8. I have just the original Mac OS X Mountain Lion on there, then Windows 8 via Bootcamp. no rEFIt installed. (I just press ALT every time I restart windows, actually as a security measure to stop tech-unsavvy thugs, who, if the laptop is stolen, think it's only a mac and don't discover my Windows as quickly as they would've, and by that time I remotely activate various anti-theft mac apps and nab them that way). SO: like the related question asks, why isn't it behaving like it should? The Windows 7 FAQ states: Will sleep eventually drain my laptop battery? If your laptop battery charge gets critically low while the computer is asleep, Windows automatically puts the laptop into hibernation mode. But this is just not happening - on my rMBP Windows 8. It seems EVERY time I set the laptop to sleep (when it reaches 10%), then arriving home and plugging it in and hoping to simply resume my work, it does NOT save the session to disk and I lose ALL my work. Who's fault is it? Win 8's (a bug, grr)? Or Apple's EFI system (maybe fixable via editing EFI options/do I have to install refit to make it work perhaps?) Or maybe changing windows power options can somehow fix the problem? Thanks for your help.

• Emails from web site sometimes blank or gibberish

  - by John Gardeniers

  Our company has one web site with an online store based on osCommerce. The system sends emails for various reasons, such as password changes, order confirmations, etc., using PHP's mail() function. We occasionally have customers report that the email they received is either blank (email is plain text format) or gibberish (email is in HTML format). In the latter case it's really just HTML that's being displayed as raw text but of course the customers can't read it. In this case the first opening tag's <, and sometimes a few more characters, has gone missing. In an attempt to determine whether this was happening only for certain customers or email systems I configured the web site to send a CC of each message to a service account at my end. Those CC'd messages always arrive intact and display correctly in Outlook. For what it's worth, it seems to happen a little more frequently to Hotmail users but is certainly not limited to them. As the web site is on a shared (Debian) host there's precious little I can do about debugging things from that end, although if I made the right request I feel the hosting company staff would help me, even though they have limited resources to spend on such matters. Any suggestions on what else I might do to try and determine just why those emails are not being received correctly by some customers, yet a CC copy arrives just fine?

• Using smartctl to get vendor specific Attributes from ssd drive behind a SmartArray P410 controller

  - by Lairsdragon

  Recently I have deployed some HP server with SSD's behind a SmartArray P410 controller. While not official supported from HP the server work well sofar. Now I like to get wear level info's, error statistics etc from the drive. While the SA P410 supports a passthru of the SMART Command to a single drive in the array the output I was not able to the the interesting things from the drive. In this case especially the value the Wear level indicator is from interest for me (Attr.ID 233), but this is ony present if the drive is directly attanched to a SATA Controller. smartctl on directly connected ssd: # smartctl -A /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 5 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 3 Spin_Up_Time 0x0000 100 000 000 Old_age Offline In_the_past 0 4 Start_Stop_Count 0x0000 100 000 000 Old_age Offline In_the_past 0 5 Reallocated_Sector_Ct 0x0002 100 100 000 Old_age Always - 0 9 Power_On_Hours 0x0002 100 100 000 Old_age Always - 8561 12 Power_Cycle_Count 0x0002 100 100 000 Old_age Always - 55 192 Power-Off_Retract_Count 0x0002 100 100 000 Old_age Always - 29 232 Unknown_Attribute 0x0003 100 100 010 Pre-fail Always - 0 233 Unknown_Attribute 0x0002 088 088 000 Old_age Always - 0 225 Load_Cycle_Count 0x0000 198 198 000 Old_age Offline - 508509 226 Load-in_Time 0x0002 255 000 000 Old_age Always In_the_past 0 227 Torq-amp_Count 0x0002 000 000 000 Old_age Always FAILING_NOW 0 228 Power-off_Retract_Count 0x0002 000 000 000 Old_age Always FAILING_NOW 0 smartctl on P410 connected ssd: # ./smartctl -A -d cciss,0 /dev/cciss/c1d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net (Right, it is complety empty) smartctl on P410 connected hdd: # ./smartctl -A -d cciss,0 /dev/cciss/c0d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Current Drive Temperature: 27 C Drive Trip Temperature: 68 C Vendor (Seagate) cache information Blocks sent to initiator = 1871654030 Blocks received from initiator = 1360012929 Blocks read from cache and sent to initiator = 2178203797 Number of read and write commands whose size <= segment size = 46052239 Number of read and write commands whose size > segment size = 0 Vendor (Seagate/Hitachi) factory information number of hours powered up = 3363.25 number of minutes until next internal SMART test = 12 Do I hunt here a bug, or is this a limitation of the p410 SMART cmd Passthru?

• How to install a private user script in Chrome 21+?

  - by Mathias Bynens

  In Chrome 20 and older versions, you could simply open any .user.js file in Chrome and it would prompt you to install the user script. However, in Chrome 21 and up, it downloads the file instead, and displays a warning at the top saying “Extensions, apps, and user scripts can only be added from the Chrome Web Store”. The “Learn More” link points to http://support.google.com/chrome_webstore/bin/answer.py?hl=en&answer=2664769, but that page doesn’t say anything about user scripts, only about extensions in .crx format, apps, and themes. This part sounded interesting: Enterprise Administrators: You can specify URLs that are allowed to install extensions, apps, and themes directly through the ExtensionInstallSources policy. So, I ran the following commands, then restarted Chrome and Chrome Canary: defaults write com.google.Chrome ExtensionInstallSources -array "https://gist.github.com/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://gist.github.com/*" Sadly, these settings only seem to affect extensions, apps, and themes (as it says in the text), not user scripts. (I’ve filed a bug asking to make this setting affect user scripts as well.) Any ideas on how to install a private user script (that I don’t want to add to the Chrome Web Store) in Chrome 21+? Update: The problem was that gist.github.com’s raw URLs redirect to a different domain. So, use these commands instead: # Allow installing user scripts via GitHub or Userscripts.org defaults write com.google.Chrome ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" This works!

• 'txn-current-lock': Permission denied [500, #13] - Subversion + Apache Configuration Issue

  - by wfoster

  Current Setup Fedora 13 32bit Apache 2.2.16 Subversion repositories setup under /var/www/svn I have two different repositories under this directory so my /etc/httpd/conf.d/subversion.conf setup in this way; LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so <Location /svn> DAV svn SVNListParentPath on SVNParentPath /var/www/svn <LimitExcept GET PROPFIND OPTIONS REPORT> AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/httpd/.htpasswd Require valid-user </LimitExcept> </Location> After copying over my repos and using; chmod 755 -R /var/www/svn chcon -R -t httpd_sys_content_t /var/www/svn chown apache:apache -R /var/www/svn I can browse my repos fine through the browser, and I can update all my working copies, however when I try to check in from anywhere I get the same error Can't open file '/var/www/svn/repo/db/txn-current-lock':Permission denied I have been working on this issue for a while now and cant seem to find a solution to my issues. It might be of some use to know that the repo existed on a different server before this, it has been now moved to this new server. Everything I have read seems to indicate that the permissions for apache are incorrect, however apache is set to run as User apache and Group apache. So as far as I can tell my setup is correct. The behavior is not though. Any Ideas? Solution The only way I was able to get this to work is to disable SELinux, it could also be done by setting the proper booleans with SELinux via setsetbool and getsebool since this is just a home server, I decided to disable SELinux and am reaping the benefits now.
