• Logstash agent doesn't run as a daemon on MAC OS X 10.9.1

  - by user329324

  I need to run the logstash agent as a Daemon on an MAC OS X System whenever the system boots up terminal: /usr/local/logstash/bin/logstash agent -f /usr/local/etc/cvlog.conf Per terminal the program is working succesfully but as an daemon it doesn't start.

• Open a terminal window & run command, then close the terminal window if command completed successfully?

  - by Caspar

  I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

• Windows PE network setup

  - by microchasm

  I'm walking through the following step-by-step guide for deploying Windows 7 via AIK: http://technet.microsoft.com/en-us/library/dd349348%28WS.10%29.aspx On step 4 (Capturing the Installation onto a Network Share), I run into a bit of a snag: attempting to connect to a network drive repeatedly fails. I'm using/deploying Dell Optiplex 380 64 bit machines, and the network cards seem to be really wonky. On the machine that I'm using to run AIK etc, the network driver wasn't found automatically. I had to manually go in and install the driver (which was found on the OEM installation media). I've since copied this to the USB key that I'm using for the Autounattend.xml so its handy. I think that because of this, the PE environment doesn't or can't instantiate the network device. Is there a way to install/configure the network device through the command prompt in PE? If not, I read about adding in the answer file path(s) to drivers, but if I did it this way, would I have to start the process all over again (i.e. create new Autounattend.xml with the PnPcustomizations path included, re-run the installation on the reference machine, install all the applications, re-make the PE iso, reboot into new PE iso)? Any shortcuts, direction, or advice would be appreciated. Thanks!

• Disk IO causing high load on Xen/CentOS guest

  - by Peter Lindqvist

  I'm having serious issues with a xen based server, this is on the guest partition. It's a paravirtualized CentOS 5.5. The following numbers are taken from top while copying a large file over the network. If i copy the file another time the speed decreases in relation to load average. So the second time it's half the speed of the first time. It needs some time to cool off after this. Load average slowly decreases until it's once again usable. ls / takes about 30 seconds. top - 13:26:44 up 13 days, 21:44, 2 users, load average: 7.03, 5.08, 3.15 Tasks: 134 total, 2 running, 132 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.1%sy, 0.0%ni, 25.3%id, 74.5%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 1048752k total, 1041460k used, 7292k free, 3116k buffers Swap: 2129912k total, 40k used, 2129872k free, 904740k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1506 root 10 -5 0 0 0 S 0.3 0.0 0:03.94 cifsd 1 root 15 0 2172 644 556 S 0.0 0.1 0:00.08 init Meanwhile the host is ~0.5 load avg and steady over time. ~50% wait Server hardware is dual xeon, 3gb ram, 170gb scsi 320 10k rpm, and shouldn't have any problems with copying files over the network. disk = [ "tap:aio:/vm/dev01.img,xvda,w" ] I also get these in the log INFO: task syslogd:1350 blocked for more than 120 seconds.

• Keep Windows Installer from using largest drive for temporary files

  - by stefan.at.wpf

  By default Windows Installer uses the largest drive for temporary storage, no matter if that's needed (meaning there would also be enough space on the system drive). Taken from http://msdn.microsoft.com/en-us/library/aa371372%28VS.85%29.aspx: During an administrative installation the installer sets ROOTDRIVE to the first connected network drive it finds that can be written to. If it is not an administrative installation, or if the installer can find no network drives, the installer sets ROOTDRIVE to the local drive that can be written to having the most free space. Now my system drive is an SSD, my largest drive is a RAID, that spins down when it's not used. Remember the SSD as system drive? Everything is silent now! Until I install something and Windows Installer wakes up my RAID again just to put a small .tmp file on it... How can I prevent Windows Installer from using the largest drive as temporary storage? Can I maybe set some access rights to disallow the Windows Installer to write on my RAID drive? Any other ideas? Thank you!

• Bind a key to a commandline command in Mac OS X?

  - by Stefan Lasiewski

  I have a Mac Powerbook running Leopard (10.5.8). Does Leopard provide an easy way to bind keys to commands which are typically run on the commandline? For example, I can open up Terminal.app and run the command /System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine which will activate the screensaver and lock my screen. What if I want to bind 'Apple-key L' to this command and execute this globally, regardless of which application is in use at the moment? Can I do this, or can I only run ScreenSaverEngine from a Terminal window? I tried to set up global keyboard shortcuts, but it seems that this won't allow me to bind a key to an arbitrary shell command: Note: You can create keyboard shortcuts only for existing menu commands. You cannot define keyboard shortcuts for general purpose tasks such as opening an application or switching between applications. I tried to set up a application keyboard shortcut, but commands like ScreenSaverEngine don't seem to be an application. Note that this Screensaver/Lock screen is just one example. I have come across other nifty commands which I might want to bind to a key-combination as well. I can do this in Gnome and Windows (with varying success). How about with Leopard? Should I be looking at doing this with AppleScript? (I haven't used that since the Hypercard days ...)

• Keyboard's media keys are blocked by a program

  - by Mike Hanson

  I've got a Microsoft Natural Ergonomic Keyboard 4000. In addition to the regular keys, it's also got keys for Web/Home, Search, Mail, Favorites (5), Calculator, and Media functions (Mute, Volume Up/Down, and Play/Pause). Everything works most of the time, and the exception is rather odd. I use a programming system called Clarion. When that has focus, the Media keys don't work. (All the others still do.) I've also discovered that programs that I create using Clarion also block the media keys (only when they have focus). This indicates that it's probably something in Clarion's Run-Time Library (RTL) that's causing the trouble. The keys will work if I click on a non-Clarion window before hitting the media key, but that's an undesirable hassle. The odd thing is that I have many colleagues with the same keyboard, and they have no problem. When I recently upgraded from Vista Professional to Win7 Ultimate, I noticed that various things "appear" differently. For example, with my old system, when I changed the volume or muted the volume bar visualization always appeared at the bottom right on the screen. Now it doesn't appear in certain programs, even when it works. This indicates an order of precedence for visual elements. I'm fairly certain a similar order of precedence exists for keyboard hooks. Depending on how the hooks are defined, and the order in which they're applied, it would seem that sometimes the IntelliType drivers don't see the media keystrokes. The Media keys probably behave differently than the rest of the "special" keys, because they are more of a standard across all keyboards, so perhaps are handled by a different driver hooking mechanism. Does anyone have any suggestions of how I might fix this problem? Is there some way to change the order of hooks? Delay the loading of the IntelliType driver? Thanks in advance!

• Attempting to set up xampp and zend server on the same machine

  - by umbregachoong

  I am attempting to set up the zend server and xampp on the same machine but I am running into problems. I came across documentation on the zend site that said you cannot do this. However the folks over at apachefriends said you can. I have since discovered that I can run some of the zendframework examples within xampp by downloading the zendframework2 library and the skeleton app from git and I am doing this right now. However, I would like to know how to set them both up without having any conflicts both for the apache2 server and phpmyadmin. (One of the frustrating things is trying to load phpmyadmin in the deployment dialog by using the zpk tool in Zend). What I did in trying to set up both servers on windows 7 is as follows: First I have tried to set up the httpd conf files separately for each server, xampp running on port 8082 , and zend running on port 8088. At the time xampp would work, but zend server would not. This is after setting up the virtual host files separately for each server. Question 1: Where are the zend server error logs? Earlier, I was able to get both of them running configuring the xampp server httpd-conf file alone, however, I experienced problems with phpmyadmin even after configuring phpmyadmin on xampp to work on a different port other than 3306. Second question here: how to set up the two mysql phpmyadmin instances so they do not conflict with each other? Here is the xampp virtual host section: ##ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs/" ServerName localhost 8082 ##ServerAlias www.dummy-host.example.com ##ErrorLog "logs/dummy-host.example.com-error.log" ##CustomLog "logs/dummy-host.example.com-access.log" common Here is the zend virtual host section: DocumentRoot "C:\Program Files (x86)\Zend\Apache2/htdocs" ServerName localhost:8088 </VirtualHost> I have looked at this httpd.apache.org/docs/2.2/vhosts/ and this http://survivethedeepend.com/zendframeworkbook/en/1.0/creating.a.local.domain.using.apache.virtual.hosts but I am obviously doing something wrong here. I also have the java sdk running on this machine with tomcat and apache and I have no conflicts- too bad this is not the case for zend server and xampp Thanks umbre gachoong

• Create a mailbox in qmail, then forward all incoming message to Gmail

  - by lorenzo-s

  I needed to let PHP send mails from my webserver to my web app users. So I installed qmail on my Debian server: sudo apt-get install qmail I also updated files in /etc/qmail specifing my domain name, and then I run sudo qmailctl reload and sudo qmailctl restart: /etc/qmail/defaultdomain # Contains 'mydomain.com' /etc/qmail/defaulthost # Contains 'mydomain.com' /etc/qmail/me # Contains 'mail.mydomain.com' /etc/qmail/rcpthosts # Contains 'mydomain.com' /etc/qmail/locals # Contains 'mydomain.com' Emails are sent without any problem from my PHP script to any email address, using the standard mail PHP library. Now the problem is that if I send mail from my PHP using [email protected] as sender address, I want that customer can reply to that address! And possibly, I want all mails sent to this address should be forwarded to my personal Gmail address. At the moment qmail seems to not accept any incoming mail because of "invalid mailbox name". Here is a complete SMTP session I established with my server: me@MYPC:~$ nc mydomain.com 25 220 ip-XX-XX-XXX-XXX.xxx.xxx.xxx ESMTP HELO [email protected] 250 ip-XX-XX-XXX-XXX.xxx.xxx.xxx MAIL FROM:<[email protected]> 250 ok RCPT TO:<[email protected]> 250 ok DATA 554 sorry, invalid mailbox name(s). (#5.1.1) QUIT I'm sure I missing something related to mailbox or alias creation, in fact I did nothing to define mailbox [email protected] anywhere. But I tried to search something on the net and on the numerous qmail man pages, bot I found nothing.

• Fix Linux-made png file for use on Windows

  - by BGM

  There is a particular icon library that I really like. Now, I have downloaded the package that has the png files inside (I know the ico files are there, but I want the png files). However, about my Windows 7 computer tells me that about 1/3 of the png files are corrupt. I usually use XnView to view the files, and it won't display the "corrupt" files. I've tried other editors and viewers and I get the same issue. Now, the png package was originally designed for Linux to be an OS-icon-package for the entire system, so I figure the png files were built in Linux. So, is there a way I can "fix" the "corrupted" png files for my Windows 7 computer? Maybe when the files were created there was some bit that was off-colour or something? Any clues? [edit] I have read in this thread that the "corruption" could happen during the extraction process. I did all the extraction with 7-zip. It was a zip containing a tar. I will try another extractor, but I don't think it will make any difference.

• Diagnosing a BSOD involving USB

  - by David Ebbo

  [Running Win7 Ultimate 64 bit] My new HP Pavilion Elite HPE-450t has been plagued by BSDO crashes since I got it about 5 weeks ago. The crashes are somewhat rare, sometimes not occurring for 3 or 4 days. I have spent a lot of time trying to isolate the device that could be at fault, but I have seen crashes with only the keyboard and mouse plugged in (as USB devices), and I tried two sets of keyboard/mouse, so I'm running out of ideas. :( The WhoCrashed tool gave this info about my latest BSOD: crash dump file: C:\Windows\Minidump\121310-11887-01.dmp This was probably caused by the following module: usbport.sys (USBPORT+0x2DE4E) Bugcheck code: 0xFE (0x5, 0xFFFFFA8008F571A0, 0x80863B34, 0xFFFFFA80092F2510) Error: BUGCODE_USB_DRIVER file path: C:\Windows\system32\drivers\usbport.sys product: Microsoft® Windows® Operating System company: Microsoft Corporation description: USB 1.1 & 2.0 Port Driver Bug check description: This indicates that an error has occurred in a Universal Serial Bus (USB) driver. The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system which cannot be identified at this time. I looked at http://msdn.microsoft.com/en-us/library/ff560407(VS.85).aspx, and for Parameter1 = 0x5, it says "A hardware failure has occurred due to a bad physical address found in a hardware data structure. This is not due to a driver bug". Should I conclude that it's a hardware issue in the machine itself, rather than a bad USB driver or USB device? Here is the MiniDump, in case someone can get more info out of it: http://ewt52q.blu.livefilestore.com/y1peS4Ce8nSK1SXghzMDoxDWXlaEu-EKCJsv25y8y5DXXIUzZ9U0_tYgFJXd939fykwa0zRmx98IW0PYG18GioqKAuARYjtspSA/121310-11887-01.dmp?download&psid=2

• Computer experiencing slowdowns and lockups despite low cpu useage

  - by user157145

  my setup i5-2300 nvidia gtx 550 ti 6 gigs ram 600 w ocz modular psu recently reformatted and already experiencing drastic slowdown as soon as windows comes up, including repeated lockups with multiple various programs reporting that they are not responsive, then recovering after 10-30 seconds. ive checked memory and hard drive both of which come out fine. despite my plethura of worthless antiviral software im forced to assume that my illicit downloading practices have lead me into some comp trouble that i cant seem to determine. i have used ccleaner, search and destroy and malware bytes, all of which have found nothing to indicate what is causing this massive slowdown. in addition according to my resource manager my computer is operating at a load of only 30-50 percent CPU useage and 60 ram useage but taking 5-10 seconds to load files and open folders, and repeated lockups of multiple programs, especially firefox which seems to go unresponsive every 2-3 minutes. any help would be appreciated, i used a program called OTL by old timer, but cant make any sense of the results i was given. any help or suggestions would be appreciated, thank you for taking the time to read this i have avast but it didnt even find anything when i had it do a full system scan, so im thinking its clueless(also nortons, avg, and ad-aware). i also have mse but it has yet to complete a full scan it takes so long (i left it on last night but when i woke up my computer had a problem and had to restart). my hard drive has 300 gigs out of 1tb open and i already used hd tune pro, which said my harddrive was fine and its not a ssd. also im a noob at comps and only have the hd that is currently inside the computer in addition im not sure if studdering is the issue im suffering. my problem is that during my typing of these responses firefox has gone "not responsive" at least 5 times, each for times of about 5-10 seconds. when i try to control alt delete to bring up windows task manager it took 20 seconds. essentially its that my computer goes super slow at bringing up anything, or taking any action whatsoever that opens a program or file and has repeated incidents where i cant even click on whatever im trying to do because it locks up. the confusing thing about these incidents is that its right after restarting where there are minimal programs running and the computer and memory load is light.

• Changing Physical Path gives blank homepage

  - by Julie

  I have two websites ASP Classic - www.company.com and www.companytesting.com. At this time of year, company.com is pointed to a folder called website2012 and companytesting.com is pointing to a folder called website2013. The contents of those two folders are almost identical, just minor changes for our season change (which I was supposed to do today - lol). Up until a couple of weeks ago, I was running Windows Server 2003. To update the "live" website, I'd make a copy of the test site folder, and rename it website2013R1, and point the test site there, then point the live site at website2012. We now have Windows Server 2008 R2 64. (I had someone migrate the websites to the new server for me.) The companytesting.com site, when I pointed it to website2013R1, worked fine. The company.com site, when I pointed it to website2013 (which worked just before, for the companytesting.com site) gives an empty page. (i.e. view source = nothing there.) There is nothing in the failed request log when this happens. I can use the Explore button/link (upper right) in IIS7.5 and see all of the files there. If I use the browse button (either in general or on the index.asp page) I get the blank page again. One weirdness about how these are set up is that companytesting.com uses a login (which I think is windows authentication - it's simply a single username and password for staff, and to keep the GoogleBots out of it). Obviously, company.com does not. But redirecting the to website2013r1 kept the login in place. (So I'm not absolutely clear whether that's attached to the folder or to the site. Hitting the company.com site after changing the path did not yield a password request.) The permissions on the folders all seem to be the same, but obviously, I'm missing something. Why isn't changing the physical path working? As is probably obvious, I'm not knowledgeable about servers. I did OK in 2003, but since it's not my main task and I'm buried right now, I have barely looked at 2008. So I may have really stupid questions when you ask me to check something.

• Our VPS is being used as a Warez mule

  - by Mikuso

  The company I work for runs a series of ecommerce stores on a VPS. It's a WAMP stack, 50gb storage. We use an archaic piece of ecommerce software which operates almost entirely client-side. When an order is taken, it writes it to disk and then we schedule a task to download the orders once every 10 minutes. A few days ago, we ran out of disk space, which caused orders to fail to be written. I quickly hopped on to delete some old logs from the mailserver and freed up a couple of GB pretty quickly, but I wondered how we could fill up 50gb will nothing much more than logs. Turns out, we didn't. Hidden deep within the c:\System Volume Information directory, we have a stack of pirated videos, which seem to have appeared (looking at the timestamps) over the past three weeks. Porn, American Sports, Australian cooking shows. A very odd collection. Doesn't look like an individual's personal tastes - more like the VPS is being used as a mule. We have a 5-attempts and you're blocked policy on our FTP server (plus, there is no FTP account with access to that directory), and the windows user account has had it's password changed recently. The main avenues are sealed - and logs can verify that. I thought I'd watch and see if it happened again, and yes, another cooking show has appeared this morning. I am the only one to know of this problem at my company, and only one of two with access to the VPS (the other being my boss, but no - it's not him). So how is this happening? Is there a vulnerability in some of the software on the VPS? Are the VPS owners peddling warez across our rented space? (can they do this?) I don't want to delete the warez in case it is seen as a hostile action against this outside force, and they choose to retaliate. What should I do? How do I troubleshoot this? Has this happened to anyone else before?

• Samba4/Ubuntu Shares Incorrectly Available to All Users

  - by Dan

  I've got my Ubuntu server working with Samba4 and got it set up as the Primary domain controller on my network with AD and all that goodness. However, I'm trying to get my Samba configuration to work with the users and groups I've defined with the Active Directory tools from Windows. For instance, I've got a share X which I want users A and B (as part of the 'management' group, known as LLGrpManager in my setup) to see, but no body else. However, after making changes to the configuration, restarting Samba, I test by connecting to the share with my Mac over Samba as user 'C' which isn't part of the management group, and I can, incorrectly, see the X share. I've tried alsorts of combinations of specifying the group with no luck at all. I've got a feeling that my global config might be too lenient or something to do with file permissions but being a bit green, I'm without clue. My /etc/samba/smb.conf # Global parameters [global] server role = domain controller server string = Office Server workgroup = LLDOMAIN realm = lldomain.local netbios name = DUMBO passdb backend = samba4 logon path = \\%L\profiles\%U logon drive = L: log file = /var/log/samba/%m.log max log size = 50 security = ads domain logons = yes domain master = auto usershare allow guests = no valid users = %S [netlogon] path = /var/lib/samba/sysvol/lldomain.local/scripts read only = no guest ok = no [sysvol] path = /var/lib/samba/sysvol read only = No guest ok = no valid users = @LLDOMAIN\LLGrpManager [ShareX] path = /data comment = Entire Data Volume guest ok = no comment = Entire Data Volume guest ok = no valid users = @LLDOMAIN\LLGrpManager admin users = @LLDOMAIN\LLGrpManager browsable = no inherit acls = yes inherit permissions = yes ... My /etc/nsswitch.conf I've also instructed the system to use the nss winbind library when searching for users or groups by adding the stanza passwd and group in /etc/nsswitch.conf: passwd: compat winbind group: compat winbind shadow: compat Permissions on the folder in question drwxrwxrwt 8 root root 4.0K Oct 28 19:11 data

• opening adobe reader results in infinite explorer.exe process creation loop

  - by irrational John

  First, apologies if the answer to this is only a Google away. I tried, honest I did. But I wasn't able to find anything about this problem posted elsewhere. I'm using Adobe Reader v9.3.2 in Windows 7 Home Premium 64-bit. If you want more system details, then just request them. What happens is that when I attempt to open a PDF by clicking "Open" on it then (1) adobe reader never opens and (2) the explorer.exe program is (apparently) recursively opened. I base this on opening the Task Manager and seeing a long list of explorer.exe processes under the "Processes" tab. Usually there is only one. When I recreate this problem, the list of explorer.exe processes are at least a page or two long. (Too many to bother counting). I "correct" this problem by logging off and then logging back on. This kills all the explorer.exe tasks. Unfortunately I don't know another way to terminate them all. Now here's the curious part. This only happens when I attempt to "Open" a PDF file. If instead I use the context menu (right mouse click on the PDF) and select "Open with" and "Adobe Reader 9.3" then Adobe Reader opens the file with no problem. It seems that there is something wrong with the setting for the default open action for PDF files. However, I have been unable to fix this by changing the Windows setting. Here is what I have tried. When I open Control Panel > All Control Panel Items > Default Programs > Set Associations I do not find an entry for file type .pdf. There are only entries for .pdfxml and .pdx. When use "Open with" on a PDF file and select "Choose default program", the check box for "Always use the selected program to open this kind of file" is disabled (greyed out). I have uninstalled and reinstalled Adobe Reader but the problem persists. While obviously no lives are at stake here, this problem is annoying the frickin' heck out of me. If I forget and recreate this bug then I have to stop everything I'm doing to stop it. Any suggestions on how I might go about fixing this?

• Exchange 2010 DAG + VMWare HA = no support?

  - by Dan

  We currently have an Exchange 2003 clustered environment (two machine cluster) that we're looking to upgrade to 2010. We recently purchased a VMWare virtualization environment (three Dell R710's with an EMC NS-120 serving up NFS datastores - iSCSI is available) that we wish to use for this new environment. I'm seeing that Microsoft does not support Exchange 2010 DAGs with a virtualization high availability solution (see links below). I would like to utilize the DAG to ensure the data stays available if one host goes down, and HA to ensure that if the physical host goes down, the VM will come back up on the other available host. Does anybody know why MS does not support this? VMWare HA will only restart the VM if it is hung/down - I don't see any difference between this and restarting the physical box if someone pulled the power... Will we only run into issues with support if it has something to do with HA/DAG failover or will they see we have HA and tell us to put it on a physical box even if it has nothing to do with HA? If we disable HA for these VM's will that satisfy them on a support case? Has anybody set up an Exchange 2010 DAG on VMware with HA enabled? Will they have any issues with using an NFS datastore? We have much greater flexibility on the EMC with NFS vs iSCSI, so I would prefer to continue utilizing that. Thanks for any input! http://www.vmwareinfo.com/2010/01/verifying-microsoft-exchange-2010.html Take a look at the second image under "Not Supported" http://technet.microsoft.com/en-us/library/aa996719.aspx "Microsoft doesn't support combining Exchange high availability solutions (database availability groups (DAGs)) with hypervisor-based clustering, high availability, or migration solutions. DAGs are supported in hardware virtualization environments provided that the virtualization environment doesn't employ clustered root servers."

• How can I recover a Fedora 12 installation that is showing signs of disk errors?

  - by Bob Cross

  I am currently overseas (i.e., very far from my normal library of tools) and my primary machine that would normally act as the data server in the performance test that we're trying to run is failing to boot to Fedora 12 properly. This is a machine that, as of yesterday, was booting fine. However, this morning, very strange portions of the boot process were complaining with messages such as "unexpected 0x0 in rpcbind" and "bad file descriptor" (I don't have the error in front of me - scavenged a windows installation to get onto serverfault). Eventually, the boot hung for a long time at the NFS service and then brought up what looked like the KDE login screen but neither the mouse nor keyboard functioned. In olden days, I would try to get to a point where I could manage to run fsck and pray that the bad sectors would come back into alignment just long enough for me to scrape the critical data off of the machine. However, now that we live in the future, it seems like our options in situations like this should be a little more varied. Is there a way to recover a Fedora 12 installation with bad disk sectors that won't boot properly? For completeness, I am comfortable working with bootable recovery distros-on-CD and such but I don't know which one is likely to work best with modern Fedora. In the absence of guidance, I'm frantically torrenting the Fedora 12 Live CD and DVD, hoping to try rescue mode before tomorrow morning.

• How to auto mark tape as free in DPM 2012?

  - by Massimo

  I have a backup server running System Center Data Protection Manager 2012, connected to a couple of tape drives (no library). I also have, of course, some tapes. Tape rotation is manual. The tape have been used before, by DPM itself (but the server has been completely rebuilt) and by other backup softwares; they are not emtpy. But they contain no data that DPM knows and/or wants to preserve, so they can be marked as free without having to run forcefreetape.ps1. When a tape is placed into the drive, it is required to perform an inventory, have it recognized as an imported tape and then mark it as free; otherwise DPM will simply refuse to use it. How can I tell DPM to automatically treat those imported tapes as free? And, of course, I do not want to reuse real backup tapes if by chance they get put into the drives before their expiration date, so the solution should mark imported tapes as free, but should not do the same with real, non-expired tapes.

• Disappearing Arial on 2 Macs

  - by drewk

  I noticed that Safari started rendering common web pages in a funny manner on two different Macs that I have. One is a Macbook Pro and the other a Mac Pro desktop. Yahoo and Google would appear all excessively bold or all italic and not at all look right or acceptable. The computers are all running OS X 10.6.3 "Snow Leopard" Turns out that "Arial.TTF" and "Arial Bold.ttf" got deleted somehow on these two computers. I restored Arial through Font Book and got my web mojo back. So questions: 1) Anyone seen "arial" strangely randomly disappear? The only thing in common is these are the only two computers out of eight on site that recently got Adobe CS 5 installed. Has anyone had CS 5 delete arial? 2) When I restored arial with font book, it goes into User fonts rather than the All fonts. Can I use Font Book to restore a font in /System/Library/Fonts or do I need to do that manually? 3) I located THIS article on the web regarding OS X fonts. Essentially, Snow Leopard did away with the older .dfont format and replaced with open True Type. There is a minimum font list, but Arial is not among them. Arial is installed by MS Office. 4) Why are web sites affected by Arial being missing anyway? If I look at the HTML source for Yahoo for example, "arial" is specified by name only in an ad. Yahoo itself does not specify a font name. In my Safari preferences, I have Times and Courier specified as the default font which is the default for Safari when installed. How does a missing Arial screw things up anyway? Thanks in advance.

• ruby on rails gitorious setup on ubuntu

  - by dogmatic69

  Ive been trying to install gitorious for a while now which required ruby and rails etc. Ive finally got rails pages serving but cant finish the installation of gitorious because the gem version is too new. the error logs say please run 'rake ultrasphinx:configure' and that gives rake ultrasphinx:configure (in /var/www/apps/gitorious) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /var/www/apps/gitorious/Rakefile:10:in `require' (See full trace by running task with --trace) From searching google this is beacuse of the wrong gem verison. Cant find a way to down grade it. apparently sudo gem update --system 1.4.2 should do the trick but ubuntu 10.10 does not like this. ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories. If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian. So i added export REALLY_GEM_UPDATE_SYSTEM=1 to .bashrc and reloaded it with . ~/.bashrc and still the same. ive tried various forms of setting this environmental variable with no luck. Ive also been told on #gitorious irc channel to add the file config/initializers/rubygems.rb with the line require "thread" to it. This has done nothing. EDIT: Just found another way which was rvm install rubygems 1.4.2 and it gave: Removing old Rubygems files... Installing rubygems dedicated to ruby-1.8.7-p334...

• Extremely high mysqld CPU usage with no active queries

  - by RadarNyan

  I have a VPS running Ubuntu 12.04 LTS with LEMP stack, followed the guide from Linode Library (since I'm using a Linode) to setup, and everything worked fine until now. I don't know what's wrong, but my CPU usage just goes up since a week ago. Today things getting really bad - I got 74% CPU usage so I went check and found that mysqld taking too much CPU usage (somewhere around 30% ~ 80%) So I did some Google Search, tried disable InnoDB, restart mysql, reset ntp / system clock (Isn't this bug supposed to happen more than a year ago?!) and reboot my VPS, nothing helped. Even with mysql processlist empty, I still get mysqld CPU usage very high. I don't know what I missed and have totally no idea, any advice would be appreciated. Thanks in advance. Update: I got these from running "strace mysqld" write(2, "InnoDB: Unable to lock ./ibdata1"..., 44) = 44 write(2, "InnoDB: Check that you do not al"..., 115) = 115 select(0, NULL, NULL, NULL, {1, 0}^[[A^[[A) = 0 (Timeout) fcntl64(3, F_SETLK64, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}, 0xbfa496f8) = -1 EAGAIN (Resource temporarily unavailable) hum... I did tried to disable InnoDB and it didn't fix this problem. Any idea? Update2: # ps -e | grep mysqld 13099 ? 00:00:20 mysqld then use "strace -p 13099", the following lines appears repeatedly: fcntl64(12, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(12, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(12, {sa_family=AF_FILE, NULL}, [2]) = 14 fcntl64(12, F_SETFL, O_RDWR) = 0 getsockname(14, {sa_family=AF_FILE, path="/var/run/mysqld/mysqld.sock"}, [30]) = 0 fcntl64(14, F_SETFL, O_RDONLY) = 0 fcntl64(14, F_GETFL) = 0x2 (flags O_RDWR) setsockopt(14, SOL_SOCKET, SO_RCVTIMEO, "\36\0\0\0\0\0\0\0", 8) = 0 setsockopt(14, SOL_SOCKET, SO_SNDTIMEO, "<\0\0\0\0\0\0\0", 8) = 0 fcntl64(14, F_SETFL, O_RDWR|O_NONBLOCK) = 0 setsockopt(14, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) futex(0xb786a584, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xb786a580, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0xb7869998, FUTEX_WAKE_PRIVATE, 1) = 1 poll([{fd=10, events=POLLIN}, {fd=12, events=POLLIN}], 2, -1) = 1 ([{fd=12, revents=POLLIN}]) er... now I totally don't get it x_x help
