• IDE <-> SATA Adapter Issue - Hard Drive Not recognized

  - by nicorellius

  I was trying to use one of these IDE to SATA adapters (Syba SD-ADA50016 IDE/SATA Converter Bi-directional IDE to SATA) and I connected a working hard drive (Seagate Barracuda 500 GB SATA 3.5 Inch 7200 RPM Version 12 Desktop Internal Hard Drive ST3500418AS). I could get the drive to be recognized by the BIOS, but I couldn't boot a Linux disc or install to the drive. I tried to install pfSense to this drive and the install failed because the setup couldn't recognize the file. Has anyone heard of these adapters giving trouble and/or not working properly? I would like to be able to use this device for newer drives on older boards.

• rsync command deletion error "IO error encountered -- skipping file deletion"

  - by Jam88

  I use rsync command to take backup of files from one of my ubuntu server to another ubuntu machine. Backup server trigger a script that use rysnc command. Here is the command I use rsync -rltvh --partial --stats --exclude=.beagle/ --exclude=.* --delete-after root@live_server:/home/ /home/live_server_backup/home /tmp/logfile.log 2&1 live_server is ssh-able without password. So it works. Now problem is with --delete-after option After all file synced .At the end I can see deletion procedure skipped.logfile error is like IO error encountered -- skipping file deletion When i tried to find log there were some error while file sync rsync: send_files failed to open "/home/xyz/Desktop/PPT_session_1_context.pdf": Permission denied (13) So my understanding is as rsync could not read all the files from target for safety reason it is skipping the file deletion. Is there any way to make --delete-after work even if there is some permission error? I do not want to use force deletion as it will be dangerous in some situation.

• How to analyze CBS.log file by SFC command to detect corrupt files in Windows 7?

  - by energydream2007

  Hey I have some problems with my Win7 so I've ran sfc /scannow and I got this message: "Windows Resource Protection found corrupt files and was unable to fix some of them..." I also told to look at the folder of the log file to find the cbs.log. After that I've ran this command to pull out the actual problems/corrupt files: findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" This command have created an sfcdetails text file (download). Can someone help me to analyze this file? I haven't found a detailed article about it so far.

• How can I auto-connect to a WPA2 Enterprise network?

  - by Demetri

  I would like my computer to automatically connect to a WPA2-Enterprise network as soon as it boots whenever the network is available, without any action needed by me. The computer already offers to connect, and even remembers the password, but I must still hit 'Enter' to connect. Also, connection does not occur if my login is at the terminal. I would like to automatically connect every time I login, no matter how I do so, unless a more preferred network is available. What is the best way to do this? I am running Fedora 19. A shell script that can be invoked at the terminal would be preferred. Connecting even if the Gnome-desktop has not launched is a must.

• m23 vs webmin vs landscape vs whatever you can propose, I need software to mantain a bunch of debian

  - by marc.riera

  Hello, I know there is landscape from canonical, but it has some $$ costs. Als there is webmin, and it can be used as a cluster management tool. Also there is m23, probably the most usable and interesting peace of manager software. But, what would you suggest to install and use on following configuration: 1) 100 desktop users, against an AD with quest authentication services installed. (ubunt8.04,9.04,9.10,10.04) 2) 50 servers (debian sid, lenny , ubuntu 8.04 and 10.04) We work on different software, so each group of persons need different configurations, each server has different pourposses, nothing is clusterized. And we have a good enough backup software. So , my objectives are: - easy install (deploy) - good reporting - easy logonscripts for users - easy bootupscripts for servers Thanks all for reading, and more thanks for your time. Marc

• Issue with Ivan Heckman's allSnap

  - by karl

  For the longest time I have used Ivan Heckman's allSnap program to better manage Windows on my pc by making them easily snap together, instead of overlapping. However on Windows 8 I cannot seem to get this to work. I suspect it has something to do with how Win8 boarders seem to have a transparent pixel around the outside of the window padding boarder, but overall I would love to get the snapping functionality back if it is at all possible. It's very hard trying to find information about this online as all I find are posts talking about snapping Metro apps to the side of the screen in Desktop Mode.

• Enabling Session Directory under Terminal Server Configuration Tool and Server Settings

  - by LPE

  Yello, I'm trying to add up a Terminal Server Session Directory client to an already fully functional Session Directory cluster which today runs two clients as well as the server. I've been reading up on both Google, Microsoft KB's as well as old documentation from an earlier employee but to no avail. The step I'm stuck at is when I open up Terminal Server Configuration Tool (tscc.msc), chooses ServerSettings. I know there should be an option saying "Session Directory" on the right hand side along with Active Desktop, Licensing and whatnot, but it's not there. I've logged on to both the other already functional clients and checked the same list and there the Session Directory option sure is both visible as well as working good with the specified information. This picture is the same view that I'm looking at at the moment, but mine is missing the bottom option that says "Session Directory" http://www.inetnj.com/doc/images/TerminalServerConfiguration.jpg Any help would be greatly appriciated. Regards LPE

• Seamless Remote Windows on Linux Client

  - by prestomation

  I really like the RemoteApp features of Windows Server 2008 Are there any solutions for similar functionality for Linux clients and a Windows server? We have users that are running Linux on the desktop and rdesktop to a Windows server, mostly for Outlook. It would be nice if Outlook could behave more seamlessly. From what I can tell rdesktop doesn't do that yet, it only implements RDP 5. I've also seen "SeamlessRDP" from Cendio, which is an extension to rdesktop, but I can't get it to work. I think it doesn't work in Vista, but that is just a guess. Any ideas? And thanks in advance. EDIT: I emailed Cendio and they confirmed SeamlessRDP doesn't work with Server 2008 for unknown reasons. It appears there is no way to do this with a 2k8 server. It's either windows clients with RemoteApp or using a pre-Vista OS with seamlessrdp

• Predictive vs Least Connection Load Balancing Techniques

  - by Mani

  I have a windows based desktop application that communicates via TCP to the application servers. (windows 2003). No sticky sessions between client calls. We have exactly 2 servers to load balance and we are thinking to use a F5 hardware NLB. The application is a heavy load types, doing not much bussiness logic in the services but retrieving quite a big amount of data at most of the times. May be on an average 5000 to 10000 records at all times. Used mainly for storing and retirieving data and no special processing of data or calculations running on the server side. I am favouring 'predictive' considering my services take a while at times to return data and hence tracking the feedback would yield some better routing as in predictive. I am not sure if the given data is sufficient enough to suggest some ideas but considering these, what would be some suggestions\things to consider\best between Predictive and Least Connections ? Thanks.

• Quickly open Windows Mobility Center in Windows 8 "tablet" mode

  - by piyo

  I am using a Surface Pro (2013). I would like to know if there is a quick way to open the Windows Mobility Center desktop program. I like to use this program because it is easy to manipulate during the "tablet" (non-keyboard, no-mouse) mode. This program has multiple ways to be started, according to From How to Open and Use Mobility Center in Windows 7 and Windows 8: (Windows 8) Press Windows key + X and select Mobility Center Open the Control Panel and select "Windows Mobility Center" Open the Run dialog and type "mblctr.exe" and press Enter key. None of these are quick and easy when in "tablet" mode. I would ideally like to swipe from right screen edge into to open the Settings pop up and select one icon that opens the Mobility Center. Alternatively, another way I would like to have implemented would be to touch the Windows icon on the tablet screen outside of the viewing area and touch an "app" to launch the Mobility Center. Alternatively, it would be nice to have a Live Tile App that duplicates this functionality.

• Bad I/O scheduler?

  - by user62367

  os: up-to-date Fedora 14. Working as a "normal desktop". It's doing very well, but if i start VirtualBox, and e.g.: install a guest on it, it just "freezez". I mean if there are disk activities on a VirtualBox guest, then the computer becomes unrespondable..even the mouse is laggin for about 50 minutes.. What could be the bottleneck? What could be the problem? If anyone has any tips/howtos to speed it up, please help! It has a normal 2,5" HDD, with 5400 RPM. Does it worth for me if i buy a 2,5" HDD with 7200 RPM? T7200 cpu, 4 GByte RAM, "vm.swappiness = 0". Thank you!

• Can I log into a Domain account without pointing DNS to the domain controller?

  - by user72593

  My situation is as follows: I have a Windows 2003 Domain Controller which is also my DNS server. I have 10 Windows XP Pro PC's which all login to domain accounts. I am about the forward my DNS requests to OPENDNS so I can regulate web access but I have (2) PC's that I would like to keep unregulated. I manually changed their DNS server IP to (8.8.8.8) which worked but that caused my login to fail (by creating a 3 minute delay before it would let me get to the desktop) when I change the DNS IP back to the IP of the Domain Controller, everything works smoothly. Question is, how can I continue to login to the domain but have a different DNS path...is this possible ?

• How can I make it difficult to install a new operating system on a certain computer?

  - by D W

  I want to host a website on a desktop computer running Ubuntu with a Windows virtual machine. I will give away the computer in exchange for a number of months of remote web hosting. I want to add some kind of lock (hardware or otherwise) so that the end users will have difficulty just reinstalling Windows and using the machine as they want, in contradiction to the contract. Ideally, I'd want the machine to die if reinstallation of the OS is attempted. It doesn't have to be completely insurmountable, but it has to be difficult enough to prevent casual reinstallation. Perhaps on bootup the system can check whether certain files exist on the computer and refuse to boot if they do not. I don't know if this is possible, but maybe BIOS is password protected, and searches for files before boot up. The files it looks for could be date sensitive, i.e. require remote replacement on a schedule.

• Can't connect to STunnel when it's running as a service

  - by John Francis

  I've got STunnel configured to proxy non SSL POP3 requests to GMail on port 111. This is working fine when STunnel is running as a desktop app, but when I run the STunnel service, I can't connect to port 111 on the machine (using Outlook Express for example). The Stunnel log file shows the port binding is succeeding, but it never sees a connection. There's something preventing the connection to that port when STunnel is running as a service?

• Terminal OS X Error when using Python

  - by Stephen

  Hey, I'm trying to learn how to program so I've installed the latest version of Python and I've been following the Byte of Python tutorial. I'm using Textwrangler I've only gotten as far as the simple "Hello World" intro and I'm already having a problem. I type out the code (just without the ""): "#!/usr/bin/python" "#Filename: helloworld.py" "print('Hello World')" and save it to my desktop as helloworld.py. I then go into terminal and type "python3 helloworld.py" and I get the following error message: /Library/Frameworks/Python.framework/Versions/3.1/Resources/Python.app/Contents/MacOS/Python: can't open file 'helloworld.py': [Errno 2] No such file or directory I was hoping someone could tell me what I'm doing wrong. If I choose to run the script from Textwrangler it operates just fine however I'm not able to access it from the Terminal. Thanks so much!

• LAMP stack security question - uploading files to server

  - by morpheous

  I am running Ubuntu 9.10 desktop on my home machine. I need to upload files from my local machine, to my web server, on a periodic basis. My server is running Ubuntu Server LTS. I want my server to be secure, and only run the LAMP stack and possibly, an email server. I do not (ideally) want to have FTP or anything that can allow (more) knowledgeable hackers to be able to hack into my server. Can anyone recommend how I may send files from my local machine to the server? This may seem an easy/trivial question, but I am relatively new to Linux - and I got my previous Windows server machine serious hacked in the past, hence the move to Linux, and thats why I am so security conscious.

• Where do deleted items go on the hard drive ?

  - by Jerry

  After reading the quote below on the Casey Anthony trial (CNN) ,I am curious about where deleted files actually go on a hard drive, how they can be seen after being deleted, and to what extent the data can be recovered (fully, partially, etc). "Earlier in the trial, experts testified that someone conducted the keyword searches on a desktop computer in the home Casey Anthony shared with her parents. The searches were found in a portion of the computer's hard drive that indicated they had been deleted, Detective Sandra Osborne of the Orange County Sheriff's Office testified Wednesday in Anthony's capital murder trial." I know some of the questions here on SO address third party software that can used for this kind of thing, but I'm more interested in how this data can be seen after deletion, where it resides on the hard drive, etc. I find the whole topic intriguing, so any additional insight is welcome.

• SuSE always logs a user in TVM session

  - by rohan

  Hello all, Our sa recently installed Suse Linux enterprise Desktop 11 on my work box and I logged in first time into a GNOME session without any problems. Last time I logged in I selected the session as TWM and that got me into the T windows manager just fine. Now when I log out and try to log back into a GNOME session, it will still log me into the TVM session. I have tried restarting the box but that has not helped. Though when I remote log in to the machine it will let me get on the GNOME session just fine. I'm guessing this is probably a really simple fix, however I am a Linux newbie and doing a google search isn't yielding me what I'm looking for. My sa cant figure what is wrong either Thanks in advance for your help, Rohan

• High RAM usage, not seen in task manager

  - by r4dk0

  Hi! I am using Windows 7 64-bit 7600, with 4Gb of RAM. I have a serious problem, since something uses a lot of RAM(3.94Gb) and I see "stairs" in taskmanager, it rises to +3Gb RAM and it drops to about 2Gb and then rises slowly again, and suddenly drops. I tryed installing this version again and other versions, newer ones, but no effect. Ive even tryed disconnecting other harddrives while I installed it, and then installed NOD32 and updated it. How could I know what is using that much RAM? P.S.: I was suspecting superfetch service, I disabled it, restarted pc, and it didnt work, since the memory is the highest point when I login with password, it is really annoying since I need about 1minute to see my desktop, neither alone try anything else. After loging in it slowly drops and after random time it starts rising again. That doesnt happen immediately after a fresh windows install. And how the drivers go, I tryed older drivers for GPU, and newest ones.

  Hi! I am using Windows 7 64-bit 7600, with 4Gb of RAM. I have a serious problem, since something uses a lot of RAM(3.94Gb) and I see "stairs" in taskmanager, it rises to +3Gb RAM and it drops to about 2Gb and then rises slowly again, and suddenly drops. I tryed installing this version again and other versions, newer ones, but no effect. Ive even tryed disconnecting other harddrives while I installed it, and then installed NOD32 and updated it. How could I know what is using that much RAM? P.S.: I was suspecting superfetch service, I disabled it, restarted pc, and it didnt work, since the memory is the highest point when I login with password, it is really annoying since I need about 1minute to see my desktop, neither alone try anything else. After loging in it slowly drops and after random time it starts rising again. That doesnt happen immediately after a fresh windows install. And how the drivers go, I tryed older drivers for GPU, and newest ones.

• Git version control with multiple users

  - by ignatius

  Hello, i am a little bit lost with this issue, let me explain you my problem: I want to setup a git repository, three of four users will contribute, so they need to download the code and shall be able to upload their changes to the server or update their branch with the latest modifications. So, i setup a linux machine, install git, setup the repository, then add the users in order to enable the acces throught ssh. Now my question is, What's next?, the git documentation is a little bit confusing, i.e. when i try from a dummy user account to clone the repository i got: xxx@xxx-desktop:~/Documentos/git/test$ git clone -v ssh://[email protected]/pub.git Initialized empty Git repository in /home/xxx/Documentos/git/test/pub/.git/ [email protected]'s password: fatal: '/pub.git' does not appear to be a git repository fatal: The remote end hung up unexpectedly is that a problem of privileges? need any special configuration? i want to avoid using git-daemon or gitosis, sorry, maybe my question sound silly but git is powerfull but i admit not so user friendly. Thanks Br

• Block IP Address including ICMP using UFW

  - by dr jimbob

  I prefer ufw to iptables for configuring my software firewall. After reading about this vulnerability also on askubuntu, I decided to block the fixed IP of the control server: 212.7.208.65. I don't think I'm vulnerable to this particular worm (and understand the IP could easily change), but wanted to answer this particular comment about how you would configure a firewall to block it. I planned on using: # sudo ufw deny to 212.7.208.65 # sudo ufw deny from 212.7.208.65 However as a test that the rules were working, I tried pinging after I setup the rules and saw that my default ufw settings let ICMP through even from an IP address set to REJECT or DENY. # ping 212.7.208.65 PING 212.7.208.65 (212.7.208.65) 56(84) bytes of data. 64 bytes from 212.7.208.65: icmp_seq=1 ttl=52 time=79.6 ms ^C --- 212.7.208.65 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 79.630/79.630/79.630/0.000 ms Now, I'm worried that my ICMP settings are too generous (conceivably this or a future worm could setup an ICMP tunnel to bypass my firewall rules). I believe this is the relevant part of my iptables rules is given below (and even though grep doesn't show it; the rules are associated with the chains shown): # sudo iptables -L -n | grep -E '(INPUT|user-input|before-input|icmp |212.7.208.65)' Chain INPUT (policy DROP) ufw-before-input all -- 0.0.0.0/0 0.0.0.0/0 Chain ufw-before-input (1 references) ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 3 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 4 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 11 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 12 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 8 ufw-user-input all -- 0.0.0.0/0 0.0.0.0/0 Chain ufw-user-input (1 references) DROP all -- 0.0.0.0/0 212.7.208.65 DROP all -- 212.7.208.65 0.0.0.0/0 How should I go about making it so ufw blocks ICMP when I specifically attempt to block an IP address? My /etc/ufw/before.rules has in part: # ok icmp codes -A ufw-before-input -p icmp --icmp-type destination-unreachable -j ACCEPT -A ufw-before-input -p icmp --icmp-type source-quench -j ACCEPT -A ufw-before-input -p icmp --icmp-type time-exceeded -j ACCEPT -A ufw-before-input -p icmp --icmp-type parameter-problem -j ACCEPT -A ufw-before-input -p icmp --icmp-type echo-request -j ACCEPT I'm tried changing ACCEPT above to ufw-user-input: # ok icmp codes -A ufw-before-input -p icmp --icmp-type destination-unreachable -j ufw-user-input -A ufw-before-input -p icmp --icmp-type source-quench -j ufw-user-input -A ufw-before-input -p icmp --icmp-type time-exceeded -j ufw-user-input -A ufw-before-input -p icmp --icmp-type parameter-problem -j ufw-user-input -A ufw-before-input -p icmp --icmp-type echo-request -j ufw-user-input But ufw wouldn't restart after that. I'm not sure why (still troubleshooting) and also not sure if this is sensible? Will there be any negative effects (besides forcing the software firewall to force ICMP through a few more rules)?

• Managing Active Directory Group Membership with a Non-Administrator Account In Server 2008

  - by Laranostz

  I am running Server 2008 R2 in an Active Directory Domain Environment. I have created a group in Active Directory and I have delegated management authority to that group to a user. I want this user to be able to add and remove accounts as needed from that group so that they are exercising some measurement of control without giving them other authority. When I have the user attempt to access the Active Directory Users & Computers Console it prompts them for Administrator credentials. They are using Remote Desktop to access the server, because they do not have Windows 7, and firewall rules prevent using the Remote Management Kit. I do not want to provide them with any level of Administrative rights except the minimum required for them to add/remove users from this group. There are two servers that 'talk' to each other in this isolated environment, a domain controller and a member server, both are only reachable through RDP. Any suggestions?
