• Windows Server 2008 R2 and OSX 10.5/.6/.7

  - by Keith Loughnane

  I'm handling a migration from a on old mac server to a Windows Server 2008 R2 machine running a 12TB(10 usable) RAID5 server. It's using an SMB share and now the OSX 10.5/.6 users can search sometimes it works but takes up to 10 minutes. The OSX 10.7 machine seems to be fine. I've looked in the root of the shared drive for a .Spotlight-V100 file (ls -a) but it doesn't seem to be there. mdutil says indexing is on for that volume and I have cleared the index using mdutil -E /Volumes/MeSharedVolume numerous times. Any ideas?

• Mysql Encryption and Key managment

  - by microchasm

  I am developing a local intranet system in PHP/MySQL to manage our client data. It seems that the best practice would be to encrypt the sensitive data on the MYSQL server as it is being entered. I am not clear, though, on what would be the best way to do this while still having the data readily accessible. It seems like a tough question to answer: where is the key(s) stored? How to best protect the key? If the key is stored on each users' machine, how to protect it if the machine is exploited? If the key is exploited, how to change the key? If the key is to be stored in the db, how to protect it there? How would users access it? If anyone could point me in the right direction, or give some tips I'd be very grateful. Thanks.

• Failing RAM, or something else? [closed]

  - by Thanatos

  I have a IBM Thinkpad T43, currently running Windows XP. Programs were crashing, XP was blue-screen-of-deathing, (more than usual) - it was basically unusable, but I couldn't get any informative error out of XP. I booted Ubuntu off a thumbdrive, which made it to the desktop, but as soon as I started to try to do anything, X segfaulted, along with several other services, followed quickly by kernel warnings and a kernel panic. I'm currently running Memtest86+ on this machine, which is spitting out numerous errors. (16k over 3 passes, and counting) The failing areas are numerous, and look something like this: 0001055da4 - XX.X MB, etc. The addresses that fail seem to cluster around 0-20 MB, 250MB, and, more rarely, 750MB, 1000MB, and 1200MB. However, a lot (but not all) of the failing addresses that I've seen end in XXXXXXX?da4 where the ? is a 1 or a 5. The machine has two sticks of RAM, one 512MB, one 1024 MB, the 512MB mapped to the lower addresses, the 1024 MB stick following. Is this indeed RAM failure, or should I consider other things before purchasing more RAM?

• loss of sound in ubuntu 12.04

  - by Leo Simon

  I'm running Linux E6520 3.2.0-56-generic #86-Ubuntu SMP Wed Oct 23 09:20:45 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux on a Dell Latitude E6530. (This is a new machine; have run the same version of linux on an older machine for a year, without this happening.) I've been losing sound regularly, though have not been able to isolate the trigger for this. I've scoured the web on this subject, in particular https://help.ubuntu.com/community/SoundTroubleshootingProcedure and Audio stopped working suddenly in 12.04 Nothing from the first site seemed to work for me. From the second site, I learned enough to be able to fix the problem when it happens, but nothing on the web has helped me figure out why the problem is happening in the first place. Patching together stuff from the web, and with some blind luck, I've found that the following steps seem to restore sound pulseaudio --kill pulseaudio --start pavucontrol -> output devices Click on the "Mute audio" icon, which mutes audio Click on the "Mute audio" icon, which unmutes audio. This obviously doesn't make sense: audio wasn't muted in the first place, but somehow, magically, toggling mute audio off and on seems to reset something. Can anybody suggest from this information why sound would be disappearing in the first place (it seems as though something is getting muted at the system level, but I don't know what)? a simpler (command-line/script) way of restoring sound, in particular, is it possible to reset pavucontrol from the commandline? Some other pieces of information that may be of use: The problem is clearly happening at the system level, since I've set up a clean new user, and this user has the same problems that I do. So user fixes like deleting the .pulse directory aren't (and don't) help. Sound works fine in Windows (dual-boot) so it's not a hardware problem Any help/suggestions on this would be most appreciated.

• Remote desktop pressing Windows key randomly

  - by wikiti

  When I'm using remote desktop at work from one specific PC it has a quirk which is really quite irritating. I'll be typing away and suddenly the Windows key will be pressed, things start minimising, explorer launches, workstation gets locked (but it locks the remote workstation, so I have that wallpaper in the background, rather than the wallpaper from the local machine as I would expect). I've swapped keyboards, even though it didn't seem to be related to hardware and it made no difference. Done some internet digging and found someone saying it's related to using windows-l to lock the workstation. I've tried to stop myself using that shortcut to see if it helps and have failed miserably :D It's happening to at least one other user remote desktopping from the same machine to a different PC. Reinstalling isn't really an option (I don't admin the PC or I would have tried it, grr), although I could probably get it done if it would definitely resolve the problem. Any ideas?

• How can I display host name on windows desktop

  - by Martin

  I do a lot of work on Windows Server 2008 remote desktops and often lose track of which host I am currently logged on to. Is there a way of displaying (without installing any non-standard apps) the host name or IP address of the host I am connected to in either the wallpaper or the notification area? I tried creating files in the desktop with the name of the machine - but my roaming profile shows the same set of desktop files on every machine, so that was scuppered. Duh! In shell windows this is easy: just set the prompt to display the host name. Surely there is a simple way of doing the same for the graphical desktop.

• mount samba share on a vmware instance

  - by Riduidel

  I've a windows machine in which a linux server is run by a "VMWare player". From the windows machine, I want some folders to be mounted on the Linux virtual server. All this is done in a maven build (which is quite irrevelant here, in fact). From what I understand, to make these windows folders available as mountable ones, I have to do the following operations Share the folders as Samba ones using net share, this I have done. Access my virtual server and check which folders are already mounted (which seems to be doable using a less /etc/fstab), this I'll do soon Mount my samba shares using smbmount All that seems to my by far too hackish code. Could the same be done using ... say ... JMX/SNMP or any other high-level technology ?

• Deleting file in Samba doesn't delete file?

  - by Jeff Welling

  Why, when I delete some files in Samba, does it not delete them but instead merely change their filename from filename.txt to ._filename.txt? This is not the behaviour one would expect when "deleting" a file, so I'm wondering if there's an option I forgot to set somewhere in the samba config. It does this to some files but not to others, I have not yet spotted a pattern to its choosiness. There is a Ubuntu 12.04 machine and a Mac OS X machine which have write (and thus delete) capability, no Windows machines have write permission.

• NTP configuration not recognized?

  - by Eugene S

  I'm trying to configure NTP on my machine but it seems that the parameters I set are not being read by the system. Below is my /etc/ntp.conf file. (I applied the most basic configuration to eliminate other issues) server 10.45.68.47 server 127.0.0.1 After I set the above configuration, I restart the ntpd process by doing the following: service ntpd restart And then I get the following output: Shutting down ntpd: [ OK ] ntpd: Synchronizing with time server: [FAILED] Starting ntpd: [ OK ] Moreover, I can see the following in /var/etc/messages: Apr 2 10:54:07 hsystem1a ntpd[21067]: ntpd exiting on signal 15 Apr 2 10:54:07 hsystem1a ntpdate[21537]: can't find host ntpServer1 Apr 2 10:54:07 hsystem1a ntpdate[21537]: can't find host ntpServer2 Apr 2 10:54:07 hsystem1a ntpdate[21537]: no servers can be used, exiting So it seems that the ntpServer1 and the ntpServer2 are being read from somewhere instead of the IPs I configured in /etc/ntp.conf. NOTE: I done init 6 on the machine just in case. Thanks!

• Access Linux Samba-Share from Snow Leopard

  - by Space_C0wb0y

  Hello there! I have a linux machine with a samba-share. Other windows machines can access that samba-share no problem. Now I have a new MacBook running Snow Leopard and I have no clue on how to access it. In finder it shows the linux-machine, but I have no idea how to access it. In some blog it said that this: `smbclient -U <username> -L <hostname>` can be used to list samba-shares. When I do it, I get `session setup failed: NT_STATUS_LOGON_FAILURE` I am at a loss here. Any help on how to approach that problem would be appreciated. Can you provide some hints or point me to some good howto?

• Can only connect to IIS site through localhost

  - by Rembrandt Q. Einstein

  I'm building a web service for my company's iPhone application, and everything's been working smoothly by running tests through localhost on the development machine. I'm now in the phase where I need to test connections from other computers within the network, and any connection other than localhost gives me a 404. My internal IP, 127.0.0.1, and computername all get 404 when connecting from any computer, either the one the site's hosted on or any others on the network. Telnet can get through to port 80, and I've temporarily disabled all firewalls on this machine (I do not have control over the external firewall, but I'm only testing connections within the network) Does anyone have a clue why this is happening? I was able to connect to the web service from other computers when hosted on a Mac via Apache, but because I'm now using a SQL Server connection I'm restricted to using IIS for Windows Authentication. Googling only provided answers related to firewalls, and mine is disabled note: I cannot use Anonymous Authentication, but even in testing that it did not affect the issue.

• How to turn ON bluetooth in Dell Inspiron?

  - by ykombinator

  I bought a new Dell Inspiron laptop a month ago. The company had pre-installed all the required software in my laptop. As such, the bluetooth used to be switched ON whenever I switched on my machine. However, a few days later, the bluetooth stopped working. I re-started the Laptop and it was ON! Now I am facing this problem very frequently. As such, the wi-fi connection doesn't work unless the bluetooth is switched ON. The bluetooth turns ON after a few re-boots and sometimes doesn't turn ON for many days. Does anybody know any trick to keep the bluetooth ON everytime I switch ON my machine. P.S: The Dell manual did not help.

• Is there a convenient method to pull files from a server in an SSH session?

  - by tel

  I often SSH into a cluster node for work and after processing want to pull several results back to my local machine for analysis. Typically, to do this I use a local shell to scp from the server, but this requires a lot of path manipulation. I'd prefer to use a syntax like interactive FTP and just 'pull' files from the server to my local pwd. Another possible solution might be to have some way to automatically set up my client computer as an ssh alias so that something like scp results home:~/results would work as expected. Is there any obscure SSH trick that'll do this for me? Working from grawity's answer, a complete solution in config files is something like local .ssh/config: Host ex HostName ssh.example.com RemoteForward 10101 localhost:22 ssh.example.com .ssh/config: Host home HostName localhost Port 10101 which lets me do commands exactly like scp results home: transferring the file results to my home machine.

• linux: upload / download difference on network shares

  - by Batsu

  I have a Red Hat Enterprise Linux 6 (with SELinux) which shows significant differences of speed between download and upload (the latter significantly slower) of files shared over the LAN. The bottleneck seems to be the output of the linux machine since I have a rate around 1Mb/s when WinXP machines download files shared (using samba) by the RHEL machine uploading files from the RHEL to a WinXP's shared folder while uploading from the XP machines to linux's shares downloading XPs' shares on the RHEL any share between Windows machines only run smooth (around 50Mb/s). Since the upload from RHEL to WinXP's share is slowed too I would exclude an issue in the configuration of samba. What could possibly determine this limit in the upload speed? update: iptables doesn't show any output rule and disabling it doesn't show any noticeable difference, so I would rule out it too.

• Visual Studio Development on Virtual Box, Boot Camp, or VMWare Fusion

  - by Eli

  I currently have a Mac, 2ghz and 2 gigs of ram, running OS X Leopard and Virtual Box with a Windows 7 Pro 32bit virtual machine. Performance on the virtual machine is fine for minor tasks but is very clunky while trying to multi-task or develop in Visual Studio 2008. What would be my best option for being able to use Visual Studio, keeping cost and time in mind? 1) Upgrade ram to 4 gigs ($100). Will this really improve my performance enough to use Visual Studio in a Windows 7 vm? Or am I just wasting time/money? 2) Reinstall/restore Windows 7 disk image as a Boot Camp partition. I assume this should improve my performance, yes? 3) Purchase VMWare fusion instead of VirtualBox. Does Fusion require less resources to run? I am open to any suggestions. Thanks in advance

• How can I restrict the backuppc client user as much as possible? (rsync)

  - by jxn

  I have backuppc making full backups of servers, but I'd like to be sure that my set up is as paranoid as possible. BackupPC is set up to backup via rsync, and it is set up to use a specific user on each client to be backed up. Because the backuppc client user has to have access to every file on the client machine and the ability to ssh into the machine without an interactive password, I'm a little nervous about securing the clients, and I'd like to know I haven't overlooked any options. Here's what I have in place: in the client user's authorized_keys file, i've included from="IPTOSERVER",command="/usr/bin/rsync" before the user's public key, so that the user can only login coming from the BackupPC server. Next, in the sudoers file, I've added this line: backuppc ALL=NOPASSWD: /usr/bin/rsync to allow root-level permissions only for the rsync command for that user. Are there other user, policy, or ssh restrictions that I can add while still allowing the backup pc client user to rsync all files?

• Super simple high performance http server

  - by masylum

  I´m building a url shortener web application and I would like to know the best architecture to do it in order to provide a fast and reliable service. I would like to have two separate servicies in different machines. The first machine will have the application itself with a apache, nginx, whatever.. The second one will contain the database. The third one will be the one that will be responsible to handle the short url petitions. For the third machine I just need to accept one kind of http petition (GET www.domain.com/shorturl), but it have to do it really fast and it should be stable enough. Which server do you recommend me? Thank's in advance and sorry for my english

• Will the Driver Support for Intel HD Graphics be Improved in 12.10?

  - by Hiranya

  I recently installed Ubuntu 12.04 on a HP Pavilion dv4 laptop. This is a core i7 machine with Intel HD graphics and also a separate nVidia VGA card. I had a lot of issues getting Ubuntu 12.04 working on this system. First there were issues booting up the live CD for installation. I worked around that by using the 'nomodeset' option. Then I continued to have similar issues after installation has completed. So I had to permanently add the nomodeset option to my GRUB boot configuration. At the moment I have a working installation but there are many issues: Ubuntu GUI is a bit flaky at times. The mouse pointer goes on and off when hovering over certain icons. Certain things doesn't get rendered properly on the screen. I can't access any of the tty consoles. Hitting Ctrl+Alt+F[1-6] gives me a blank screen. And once that happens I can't even come back to the UI by hitting Ctrl+Alt+F7. I've realized that tty consoles are actually working. I just can't see the text. If I enter a command like 'sudo reboot' into the empty screen the machine reboots. Can't get external displays (monitors, projectors etc) working. But I think this is probably because the VGA out is wired to the nVidia card which is not being used by Linux. colord program crashes every now and then triggering a popup message. So my main question is, will the support for Intel HD graphics be improved in the next release? Or will I have to keep using the nomodeset option in the new release too? Also I appreciate if anybody can shed some light on any of the issues listed above. Thanks in advance.

• Combine OS partion with data partition on NAS4Free/FreeNAS

  - by Pak

  I recently built a NAS4Free (formerly FreeNAS) machine using a 256MB (yes, MB) USB drive for the OS. When I did the original install, I had the bright idea of making the OS partition just big enough for the OS and a then creating a second partition using the remainder of the drive to store stuff pertaining to the OS. I never really found a use for the data partition and I ended up running out of space on the OS partition, so now I'd like to combine the partitions into a single partition. Is this something that is possible to do while everything is up and running? If it comes down to it, I can take down the machine and do a fresh install of the OS using the entire space of the USB drive, but I'd like to use this as an opportunity to better familiarize myself with FreeBSD/UNIX type systems. If this is possible, will it interfere with the NAS4Free things? The data partition shows up in the web interface under the disks section. If I end up manually changing the partitions, I'd be concerned with NAS4Free getting confused by the missing partition.

• Is there a way to share a scanner with an Airport Extreme?

  - by Electrons_Ahoy

  I've got an Airport Extreme as my home network's router. (Sidebar: I love it.) The printer sharing is pretty phenomenal - I've got my printer hooked up to the base station and all the machines in the house can print to it just fine. However, I have one of those combined scanner/printers, and nothing on the lan seems to be able to see the scanner. Is there a way to get the Airport Extreme / Bonjour to also share the scanner half of the device? For the record, this is an all Windows LAN, so I'm using Bonjour for Windows to get the print sharing to work. Also, I'm hoping to not add a whole stack of extra software to the ecosystem - only one machine in the house needs the scanner, so I can just plug the printer back into that machine and share the printer that way. Still, the Airport and Bonjour seem fancy enough that this seems like it should be doable.

• Using m0n0wall in a VM for testing.

  - by tombull89

  I'd like to use m0n0wall inside a (VirtualBox) VM to play about with and see what it can do. Ultimately the goal is to have a number of virtual machines connected to a internal virtual network which goes through to the m0n0wall VM, and then the m0n0wall box connected to the internet through NAT or a bridged addaptor on my host machine. I can find out how to set the LAN and WAN addresses, but this seems to be only for using m0n0wall as a router intead of attached to another router. Let's see if I can diagram this: [Virtual Machine]---Internal (VM Only) Network ---[m0n0wall VM]---Bridged/NAT Addaptor---["real" router]---Internet. Can anybody suggest how I should do this or am I thinking m0n0wall isn't meant to be used like this?

• Recently reloaded computer, now have trailing effect when windows overlap

  - by Tony

  I recently did a clean install of my home machine and I am having a weird graphical error where if I move one window across the top of another it leaves a trail: I have the most recent NVIDIA drivers installed and nothing new is installed on my machine than before the reload (and I never had this issue before). I have two monitors and it happens on both so I'm sure it isn't a hardware issue (the card and my main monitor are also both less than 6 months old) I've also noticed a ripple when scrolling down on web pages which I believe is related. Any ideas what might be causing this and solutions to fix it?

• using wbadmin to backup and recover

  - by g7rpo

  HI I am using wbadmin to perform backups of a specific folder, primarily to backup my VHD files this is working fine but I tried to recover the files today using a different machine to the one which created the backup and couldnt get the machine doing the recovery to 'see' the backups. Is there a way to do this as my worry is that if I have a failure on the host which is perfmorming the backups I need to be able to install hyper-v on another host and recover the backed up VMs to there until I can rebuild the host. It appears that this isnt possible, I am hoping I am missing something. Any help would be greatly appreciated.
