• SBS 2008 File access restrictions after 5:30PM

  - by Moif Murphy

  Hi there, SBS 2008, I have an issue whereby a user can't access a file after 5:30PM. They get the message: "cannot be accessed. The file may be corrupted, located on a server that is not responding, or read only I've checked the logon hours on the AD User account in question and there's no restrictions there. I have noticed that the account in question does not appear in the SBS Console, only in ADUC which means the account wasn't added using the wizard. It's a long shot but would that make a difference? Other than that I'm pretty stumped, any suggestions welcomed. Thanks

• Mimicking Google's Persistent Disks -- Is this a logical FreeBSD disaster recovery strategy?

  - by Casey Jordan

  I am looking into FreeBSD to provide a more comprehensive backup and disaster recovery strategy for database servers. Ideally I want to mimic what google is doing with "Persistent disks" https://developers.google.com/compute/docs/disks#snapshots I am hoping someone who knows more about FreeBSD can validate these ideas/questions: I have read that FreeBSD can take instant disk snapshots, therefore if our databases trigger a consistent state (Block all writes, and flush buffers to disk), I would assume I could take snapshots every hour without service interruption for more than a few seconds. Is this true? Is there a way to take snapshots and back them up offsite easily? Can this be done incrementally as to save how much disk space is actually used? If a rollback needed to be done, how long does this typically take? Is a rollback also instantaneous? Thanks!

• Is the sql backend right choice for LDAP?

  - by skomak

  Hi, I have felt some troubles with LDAP dif database after unexpected system reboots. This databse was only read so it is confused why database have had errors. So im searching for replacement of this database. I think SQL would be more reliable. What do you think, is it? I need to know how much performance loss i'll meet then. How many more IOPS(I/O per second) in percentage I loss too. Thanks in advance, skomak

• SPF records - what are the differences ?

  - by progeny

  I'm trying to set up an SPF record for my domain. I've read the RFC, been to Wikipedia, openspf.org, etc. but I'm still confused. What is the difference between 'a' and 'mx'? When do I use 'mx: rather than 'a:' or 'include:'? What's the point of '?all' (Neutral result) except for debugging? Why do so many people use '~all' (Softfail) instead of '-all' ? I've been to the Wizard (http://old.openspf.org/wizard.html) but I don't understand the questions.

• Constantly visible notification and access icon for Empathy in Gnome 3

  - by aef

  Since a short while I'm using Ubuntu Oneiric Ocelot (11.10) with gnome-shell (Gnome 3) and I'm trying to get accustomed to the default Empathy Instant Messaging client. One mayor problem for me (coming from Gnome 2 and Psi) is that there is no constantly visible icon which makes it clear (for example by changing its icon or showing an animation) if there are incoming messages which I did not read already and which lets me jump into them with one click. Also I'm missing a way to bring up the contact list or hide it away with a click. I sometimes have real problems even figuring out how to even open the contact list up again. Is there a Gnome 3 extension or some other trick available to display such a notifier in the top bar? I'm talking about something just like the sound and network controls which are already located there. I know that there are notifications in the lower notification area (former system tray), but as it is only visible as I move the mouse in the lower right corner of the screen, its useless for me.

• Domain Key Entries

  - by natediggs

  More BIND DNS questions. OK, my changes the the zone files are no propagating out. Now I'm having a problem with the domain key entries I'm trying to create. I'm starting by trying to set the domain key policy. To do so I added the following entry to my zone file (actual domain XXX'd out). Based on everything I've read this is properly formatted and should work. When I try to verify the DNS entry for our domain it doesn't how up. _domainkey.XXXX.com TXT "t=y; o=~;" Is there something I'm missing? Nate

• preloading RSS contents in thunderbird, before actually reading them

  - by Berry Tsakala

  i have thunderbird 3.x, and i'm subscribed to several RSS feeds. How can I tell thunderbird to load/download any new RSS items in the background? The usual behavior with RSS feeds is that it download the headrs, or few introductory lines from the contents, but only when i'm clicking a feed item it starts loading "for real". I really want to receive the feeds and not to wait for them to load, the same way i receive emails in any email client - all messages are fully downloaded at once. there could be several reasons, BTW. - e.g. if i have short connection time, i'd rather connect, sync everything at once, and read it later. - or if i have a slow wifi connection, it's annoying to wait for each and every message, but the computer is idle while reading.. thanks

• Is it safe to compress my Windows 7 %USERPROFILE%\AppData folder?

  - by Kev

  Having just read Scott Hanselman's latest blog entry, Guide to Freeing up Disk Space under Windows 7, he suggests turning on NTFS compression which I already do for a number of less travelled folders that contain static files such as downloads or images. However I am wondering if it's wise to turn on NTFS compression for the whole of my %USERPROFILE%\AppData folder? My system drive is a 128 GB SSD residing in a Dell Precision T5400 3Ghz Quad Core Xeon workstation so I ought not to notice the extra cycles used to compress and decompress files on their way to and from the disk. However would there be any good reasons not to do this? In fact could I safely compress the whole of my %USERPROFILE% folder?

• Need information on a filesystem error:

  - by abc

  I have console access to an embedded linux device. This device has flash memory part of which is partitioned as a FAT filesystem. Its running linux-2.6.31. However I am seeing these errors on the console these days and the FAT file system becomes read only. 111109:154925 FAT: Filesystem error (dev loop0) 111109:154925 fat_get_cluster: invalid cluster chain (i_pos 0) 111109:154925 FAT: Filesystem error (dev loop0) 111109:154925 fat_get_cluster: invalid cluster chain (i_pos 0) I cannot understand why this happened? What is the root cause? And what is the fix? I would appreciate answers that can point me how to investigate the possible root cause of this issue on the device.

• Do I need a driver to use use Samsung P2770H Monitors with OSX?

  - by anagi

  I am would like to buy this Samsung monitors to be used with my macbook pro. However, when I went to the website of the Samsung, I couldn't find any driver for osx. I also read on some forum, that apple doesn't work WELL with most 3rd party monitors, because apple is trying to get people to buy their expensive monitors. While this might be an incentive, I thought the decision to manufacture a driver was up to Samsung and not apple. But then since I don't know much about this subject, I thought of getting the online expert opinion. So to be be more precise: Does anyone if this particular monitor works with OS X?

• Samba Permissions

  - by Nelson

  I have Samba set up on a Fedora 15 Machine. All looks well except that there's something nagging and I don't know what exactly is causing it. I have a public share on the server which is accessible by everyone and its permissions is set to 777. When one person opens a document under that share and closes it after working, the other person who opens it can't edit or save it because it opens in read only and shows that it's still open on another computer. What might be causing this and how can I resolve this?

• Is UEFI more or less vulnerable than Legacy BIOS?

  - by Eric

  Is UEFI more secure than BIOS on a Windows 8.1 machine? Is UEFI vulnerable to malware in ways that Legacy BIOS is not? Is it correct that UEFI can connect to the internet before the OS (or anti-virus program) has loaded? On some boards, UEFI settings can be changed in Windows. Do these things affect PC security? I have read that BIOS on an MBR disc can be vulnerable to 'rootkits' There have been reports that suggest UEFI secure boot may not be infallible. Is UEFI better at defending against malware than BIOS?

• Isn't ethernet used for LAN?

  - by Alraxite

  I'm not really knowledgeable about networking stuff, hence the stupid question. I read that ethernet was used for LAN connections but I'm pretty sure what I'm currently using to connect to the internet is 'ethernet'. The only knowledge that I have about networking is that there are two types of internet connections: Dial-up and broadband. And broadband can be either DSL or cable. So where does ethernet come from? The only thing I can tell is that I have a DSL model and there is an ethernet port at the back of it, a cable from which runs to a port in the back of my CPU. So, can ethernet be used to connect to the internet? Is it a subtype of DSL? I'm really confused about this, so I would really appreciate if someone could explain this to me. Also, I will apologize if this isn't the right place to ask.

• MSWord table shading prints too dark

  - by Relaxed1

  My friend has a very light shading in his MSWord tables. However they still print too dark to read the text. When emailed to a colleague using the same printer, it prints light nicely. However they cannot find any setting that is different between them. Any ideas? Thanks! (P.s. for myself this would help for non-tables also, when 'highlighting' text. I do know that 'shading' gives more colour options for non-tables, but it would be nice to know anyway. Thanks)

• Domain controller policies having administrative issues with program installations

  - by russ

  I have an issue with our domain and policies where a user needs administrative rights to install a program and someone provides the credentials for the 'run as admin' or 'run as other user' it will always show an error: Cannot find specified file on the drive. So we cannot install programs for our employees. How I fix it is I add the user to administrators, force a policy update, have them reboot, run as administrator and install it that way. Then remove them after and update the policy. Another way was to right click the install file (.exe/.msi) and add the user and administrator as an owner with full control. Only works when we have the installation file. I have no idea how to fix this and I can't find a relevant thread or QA about this problem. I can only find users having issues on their home computers not on a domain. Any help and threads to read would be great!

• Running commands on FreeBSD Live CD

  - by jmc

  I'm running FreeBSD 9.1-PRERELEASE on a vps running on XEN virtualization, I tried to update it to 9.1-RELEASE but mergemaster toasted my /etc/master.passwd and /etc/passwd so what i have now is a blank copies of the two files. What i did is use a mounted Live CD and mount my root partition to /mnt and manually re listed every entry to /mnt/etc/master.passwd and /mnt/etc/passwd from another freebsd server. I believe that everytime you edit master.passwd and passwd you have to run pwd_mkdb but this gives me "Read Only File" error. What I plan to do is enable PermitRootLogin and PermitEmptyPassword first so I can login as root first before I redo necessary changes again. But i have to run pwd_mkdb, so is there a way to run this command from Live CD?

• Running multipul lines through a server.

  - by Kevin Roberson

  I am looking to buy numbers in bulk on DIDx.net. After I purchase the numbers in a particular area code, I want to forward those numbers to other numbers that are outside of that area code. This way it will be seen as a local call versus long distance. I have the customers but I don't have the system I need. I have read about Asterisk, VOIP, SIP, and BYOH. But I have no clue what will be the best system for me. Does anyone have any idea what my next step should be when it comes to hardware and software? Or what type of operating system I should use? I basically want to set up a system like GoogleVoice & Phonebooth.

• Windows 8 on iSCSI with LIO target: thin provisioning

  - by LubosD

  I have installed Windows 8.1 on an iSCSI target. This target is provided by Linux LIO and is backed by a sparse file. One of the reasons I created such an installation was thin provisioning. In other words, when I free disk space on Windows, LIO should punch holes into the file, thus free storage space on the Linux server as well. I have checked my kernel's sources and the SCSI UNMAP command is really supported for file-backed targets. On the other hand, deleting files on Windows doesn't lower the amount of space taken by the backing file on Linux (checked with du). Actually, the backing file sometimes grows even more. Some sources on Google say Win8 should support UNMAP/DISCARD on iSCSI, but even in Wireshark I only see ordinary read and write commands when files are being deleted. Any way to fix or troubleshoot it?

• Windows Server 2008 scheduled tasks cannot create files

  - by Nick Cartwright

  We have a series of tasks which, when run interactively over the command line run fine creating temporary files and (importantly) logs and backups. When we schedule the task with Administrator privileges to run at the highest priority, however, no logs or temporary files are created! All the directories have read/write privileges as administrator. Has anyone else experienced this?? We are running Windows 2008 Server & the job is configured for 'Windows Vista or Windows Server 2008'. Any help would be much appreciated! OK - so we installed Z-Cron and it works perfectly.... Still a really really strange error from Windows 2008 Task Scheduler, but a solution is perhaps not quite so urgent now we have Z-Cron working!

• Share the DVB card on windows 7 [closed]

  - by Bashar Kernel

  I have 2 computers connected to a router and I have a DVB card in one of them. I want to use the one DVB card to feed both of them. I read about it and I know that I want to share the DVB adapter with the Internet Connection Sharing on the LAN network. But when I use the connection sharing, I lose my internet access I tried to use "Bridge Connection", but then I also lost my internet access too. Can any one tell me how to fix this problem? And how to view the channels (for example how to use the VLC)?

• How should a small team using multiple OS's deploy over github?

  - by Toby

  We have a small development team that have recently moved to using github to host our projects. The team consists of three developers, 2 on Windows and 1 on Mac. I am currently researching the best way to deploy applications to our Linux servers (dev and production). Capistrano running locally would be ideal but from what I read this won't work for Windows machines. It looks like the best way is to use a post-receive hook in github, I can see how this would work for auto deploying to dev, but I don't see how we could then deploy to live. I have found paid projects like http://www.deployhq.com/ but it feels like something that a quick bit of code should be able to do for free, I just can't seem to get myself pointed in the right direction! I was wondering what would be considered best practice for small team deployment involving multiple local OS's and github.

• Expertise Location [closed]

  - by Alexey Shatygin

  Is there some really working implementations of the expertise location systems exist? It is very hard to find anything about it. What sources to use, what to read, where to look? I've started with reading David W. McDonald's, Mark S. Ackerman's overview "Just talk to me" and now need just something more detailed. For those, who voting this question to be closed for off-topic: it is connected to IT sphere, if you don't know what it is - why ever vote? http://en.wikipedia.org/wiki/Expertise_finding http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.40.4654&rep=rep1&type=pdf

• Ubuntu apt-get install (--download-only) executed from another machine on behalf of mine

  - by Maroloccio

  I have a server on a network segment with no direct or indirect access to the Internet. I want to perform an: apt-get install <package_name> Is there a way to somehow delegate the process of downloading the required files to another machine by exporting the server configuration so as to satisfy all dependencies while running: apt-get install --download-only <package_name> Can, in effect, apt-get install read a configuration from an exported archive rather than from the local package database? Can the list of packages to be downloaded be retrieved, along with an installation script to perform the installation, instead of the actual packages? (a further level of indirection which would help me schedule this with wget at appropriate times...)

• Windows 7 to search a network drive

  - by John

  Is there any way that I can have windows 7 clients be able to go to "start" and type in the name of a file that is located on a network drive? I have read that this is possible through indexing, but to get through the indexing steps I need to make files available offline. This network drive I speak of has about 2tb of files on it. How in the heck can I keep all this straight. I imagine there would be syncing errors everywhere if I were to make all of these files available offline. Not to mention not all files being current due to the large amounts of files. Anyone have suggestions?

• How to retry connections with wget?

  - by Andrei

  I have a very unstable internet connection, and sometimes have to download files as large as 200 MB. The problem is that the speed frequently drops and sits at --, -K/s and the process remains alive. I thought just to send some KILL signals to the process, but as I read in the wget manual about signals it doesn't help. How can I force wget to reinitialize itself and pick the download up where it left off after the connection drops and comes back up again? I would like to leave wget running, and when I come back, I want to see it downloading, and not waiting with speed --,-K/s.
