• Clean installation of RHEL 5.5 claims package "desktops" is missing

  - by TKguru42

  Hi all, I'm a student worker in the CS department of my university, so please forgive me for any unprofessional descriptions. Simplified explanations are appreciated. I recently replaced some bad graphics cards in a few public workstations. The machines are all the same model. Before putting them back on the network I did fresh installs of RHEL---first I tried 5.4, but yum update ran into all sorts of ugly dependency errors and if I tried to remove any of the problematic packages, the whole operating system FUBAR'd. Using RHEL 5.5 gave me the same errors during install saying that "java.1.5.1-sun*" and "desktops" were missing, but yum update didn't have any dependency problems. Now that I tried logging in through the GUI, I encounter no GUI past the standard RHEL login page. The desktop is a uniform light teal and there's no system tray. An xclock window and an xterm window are open, and Firefox opens automatically, but that's it. Nothing else. What's REALLY confusing is that the computer claims that gnome is already installed, except it clearly isn't working. Any help or advice is greatly appreciated. If it helps, our department uses kickstart to run our standard Linux installs. I can try to get the script if that would be of use. Thank you!

• Am I safe on Windows if I continue like this?

  - by max

  Of all the available tons of anti-malware software for Windows all over the internet, I've never used any paid solution(I am a student, I have no money). Since the last 10 years, my computers running Windows have never been hacked/compromised or infected so badly that I had to reformat them(of course I did reformat them for other reasons). The only program I have for security is Avast Home Edition, which is free, installed on my computers. It has never caused any problems; always detected malware, updated automatically, has an option to sandbox programs and everything else I need. Even if I got infected, I just did a boot-time scan with it, downloaded and ran Malwarebytes, scanned Autoruns logs, checked running processes with Process Explorer and did some other things and made sure I cleaned my computer. I am quite experienced and I've always taken basic precautions like not clicking suspicious executables, not going to sites which are suspicious according to WOT, and all that blah. But recently I've been doing more and more online transactions and since its 2012 now, I'm doubtful whether I need more security or not. Have I been just lucky, or do my computing habits obviate the need to use any more(or paid) security software?

• How to fix Asus Eee PC 900 startup issues after failure?

  - by EBrown

  My Asus Eee PC 900 shows no signs of life. I push the power button and get no response from anything. No lights, no power, no boot-up screen. It has been like this since I received it from a friend. I asked her what happened and she said that smoke came from the keyboard, it shut down and hasnt turned on since. I have tried removing and cleaning the RAM, the computer charger still connects and works, but the battery receives no charge and the computer won't power on. Any ideas as to what is going on?

• Adding/Removing Users For Permissions in XP

  - by Brian

  Hello, I have some specific folders that I grant members of my team permissions to. So I'll share a specific folder and add them as permissions. But after they are done I usually remove them from the list of permitted users. I was wondering if it's possible to setup a bat file to achieve this, to make my life easier. I was wondering if WMI or powershell has those kinds of capabilities. Just curious. Thanks.

• Time Capsule + Ubee Router?

  - by Charlie

  I can't for the life of me figure this out. I recently had TWC installed in my house, and wanted to disable the NAT and router functions of it. I have a Time Capsule hooked up to it from LAN1 (on the Ubee) to the WAN port on the TC. The problems started occurring here. I figured the settings would be these: Ubee Configuration mode: Bridge DHCP: Off TC IPv4: 192.168.100.2 Subnet Mask: 255.255.255.0 Router Address: 192.168.100.1 DNS Servers: 8.8.8.8, 8.8.4.4 Router Mode: DHCP and NAT But using those settings, my TC says "Double NAT", so I have to change it all around to the default settings of the Ubee using NAT. This leads me to believe bridge mode doesn't actually turn off NAT...

• How can I get all my itunes files from multiple computers onto my new PC?

  - by jasondavis

  Managing my itunes files (music,video,tv shows, iphone apps) is a really hard task and I have not had much luck yet. If I had a single PC for the rest of my life with the same hard drive, it would work great but infortunately it cannot be that simple. I just build a new PC as my old hard drive crashed with all my itunes purchased songs, video, etc. So is there anyway to get itunes to recognize that I own all them and let me re-download everything? As I see it so far, it knows what I own by my itunes account login (it knows if I purchased a file or not ever) but does not seem to let you just re-download everything to a new PC or new hard drive. I realize I should of had backups but I didn't. My backup plan is a work in process and it is getting much better but that doesnt help with my situation at the moment. So I am asking for any help, ideas of how to retrieve all my previous itunes purchases?

• Defrag/TRIM settings for hybrid hard drive?

  - by Joel Coehoorn

  I recently acquired a momentus XT hybrid hard drive. This is a tradition spinning HDD with a small SSD portion for frequently used files. Normally, you are not supposed to defrag SSDs, as it does not help performance and can significantly reduce the life of the drive. But you do need to defrag an HDD to keep good performance. So where does that leave us for hybrid drives? Do I need to turn off defragging in Windows to preserve the SSD portion? Is the on-disk controller smart enough to handle defragging correctly? Is there some utility I need to set it up that I missed? Additionally, for SSDs you normally want to check for and enable TRIM support... but this makes no sense for a HDDs. Where does that leave us for hybrid drives? Should I try to enable TRIM or not?

  - by Mike

  Hello, I have a pretty big problem. My son just moved back to work for me in my firm. We set his computer up and installed Outlook03 connected to an Exchange 2000 server.

Only other software that's installed are QuickBooks03-09 and Lacerte00-08. Edit: The calendar is in the public folder

• How can I synchronise my Outlook Calendar with Google Calendar (preferably using a free/open source tool)?

  - by Kuf

  How can I synchronise my desktop Outlook calendar with my Google Calendar (Outlook - Google)? I saw the question Free tool for Synchronizing Google Contacts and Calendar with Outlook, but the solution that was suggested there is no longer available - Google Sync End of Life. There are tools that required a payment, like SyncMyCal, gSyncit and OggSync, but I am looking for a free / open source solution. One can download Google sync, but when trying to use it there's an error: For now, I use OggSync to synchronise, but as a freeware it allows to synchronise manually only, not automatically, so I have to remember to synchronise after every change. I checked Mozilla Sunbird, but I couldn't find any relative posts on how to synchronise Outlook - Google using it. Just to be clear: I'm not looking for software; I am looking for a solution. What can I do if sometimes software is a solution?

• Microsoft Word 2008 on the Mac sometimes "Disappears" documents, really.

  - by Ross Charette

  This happens in a computer lab environment, has happened at least 3 times. We are running Microsoft Office 2008 for mac on Leopard, everything is updated. Our user's home directories are on a network drive, but the /Library/Cache folder is running locally. Typically a student will have a Word file that they have been working on, it's been saved before they even logged onto the computer that day. They log on, open the document, click the save icon (not go to File Save), sometimes even save multiple times, then close Word. The document is now gone. It's not hidden, there are no autosaves or anything in the Cache folder. Definitely not in the trash or trashes folder. It can't find it when you click on it in 'recent documents'. Searching meticulously though every folder in their home drive turns up nothing. They look using Finder, I look ssh'd as root into their home using ls -la. I look for similar files in case they renamed it by mistake. It's gone. Disappeared. Vaporized. It's happened to at least 3 different users in the past year. Much whining. Any idea?

• RDP windows key jamming

  - by VBwhatnow

  There is a known bug in RDP; if you lock the screen while connected to a computer the computer you are connected to will have its windows key jammed. There are a few work arounds that involve hammering the windows key and re-locking the screen but this isn't a bug I want to put up with anymore. Microsoft has said they wont fix this bug because it's XP specific and they are only working on security bugs now because XP is at end of life. Is there any way I can fix this or am I just going to have to find an alternative remote desktop software.

• Winodws server 2003 Setup

  - by Barracksbuilder

  I work at a university maintaining the computer science department server. I am looking for a more economical way to stream line the set up of student accounts. CS students are granted a Username and password an IIS virtual directory, FTP virtual directory, and a mysql database. Server is running windows server 2003R2 (Possibly migrating to 2008R2) The server is running a domain though no students physically log a terminal into it (No computers are part of my domain.) Creating the account is a manual process. I did right a PHP script to query the Universities AD and copy the information and write it to my AD. I then have to create basically the users home directory. I tried having AD do it but since the user never physically logs in it never creates the directory. Permissions on this folder are set to User - full, Instructors (group) - full, Users (group) - read, IUSER - read. Inside of the users folder their is a "Private" folder with permissions User - full, instructors (group) - full. Next step is IIS I create a virtual directory in the default web site pointed to the users home directory so they have a website. Same goes for FTP virtual directory in the default ftp configuration to allow the users to upload files to their website. Mysql I have to create a user and password then create a mysql scheme (database) full access for the user and full access to the instructors account to be able to access the students database. All of this is done manually and takes me a week to do. The closest description is maybe a shared hosting environment. Is there a better way to do this? Scripting wise, or better structure setup?

• VGA passthrough and desktop virtualization

  - by Zacariaz

  In short, my dream is to have one machine with multiple paravirtualized desktop and server guests, one of which has to be a Windows desktop with powerful graphics. As Windows can't be paravirtualized in the normal sense of the word, I was quite happy when I heard about VGA passthrough, but then I read on. As I understand it, such a setup would mean that the Graphics will be dedicated to one particular guest, thus you wouldn't be able to switch between guests. If this is in fact so, would someone please explain to me what the purpose/use of VGA passthrough is? I can think of no real use for it. Yes it's a cool technology, but to me it seems pointless. It's true that it's possible to passthrough individual VMs to separate GPUs, which is also cool, but in the end I should think that two seperate computers would make life a whole lot simpler. Again it seems rather pointless.

• Any way to disable specific CPU idle (Cx) states?

  - by Philippe

  I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy. FYI: I'm running Windows 7 64-bit

• Ubuntu 10.10 and packetfence

  - by BrNathan

  I asked in the Ubuntu area, but thought I would get a better answer here. Was anyone able to install packetfence on Ubuntu 10? I tried a tutorial, but didn't have any luck. Some of the services installed and are working apache with php, snort, pfdetect, and pfdhcplistener. I can even get info with pfcmd node view all, but for the life of me I can't get it to work with apache2. When I run pfcmd service pf start I also get an error uninitialized value $_[7] in join at /usr/local/pf/lib/pf/class.pm line 170

• how do I concatenate a regex in a bash alias?

  - by Rodreegez

  Hello, I can't for the life of me how to create an alias that will switch to a given project directory. I keep all my projects in a folder called Projects i.e. ~/Project/blog ~/Project/whatever I'd like to have an alias along the lines of p whatever that would equate to cd ~/Project/$1 where $1 is whatever is given to p. I have tried various combinations of alias p="cd ~/Projects/\$1" with all the usual suspects for regex escaping but I can't quite get it. Any ideas?

• Oracle (xe) 10 vs 11 . Have I lost the SQL tuning pages ? Am I going out of my mind?

  - by Richard Green

  Ok .. so perhaps the title needs calming down a bit, but basically I am after the xe 11g equivalent of the pages that you can see here : http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/getstart.htm#BABHJAGE whcih you can then navigate to stuff like "top 50 queries" and "longest running queries" etc etc. For the life of me, I can't find that on the most recent xe edition. Please can someone direct me to where I might find these very useful admin pages ! Or was I imagining it all along :-/ Edit: These are the pages I am after: http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/monitoring.htm

• Debian virtual server hangs on reboot, need help debugging

  - by BubuIIC

  I'm admin of a Debian 6 virtual server. I've been trying to diagnose this problem for a while but haven't gotten anything. The server hangs every time I want to reboot it. All services seem to be shutting down, I lose ssh connection. Then nothing. I have to restart it through the hoster's web-interface, which just gives me the options "Normal Boot" and "Rescue System". Normal boot then brings the server back to life. Possibly (probably?) related, the server does not boot into a newer kernel version, it's running 2.6.18 right now, but installed is actually 2.6.32. I don't know whether it hangs on shutdown or on startup, but booting through the web-interface works (except the kernel part). Am I missing something obvious? Where should I start looking? I have no idea how to diagnose the problem.

• A unique identifier for a Domain

  - by jchoover

  I asked a question over on StackOverflow and was directed to ask a related one here to see if I could get any additional input. Basically, I am looking to have my application aware of what domain it's running under, if any at all. (I want to expose certain debugging facilities only in house, and due to our deployment model it isn't possible to have a different build.) Since I am over paranoid, I didn't want to just rely on the domain name to ensure we are in house. As such I noted the DOMAIN_CONTROLLER_INFO (http://msdn.microsoft.com/en-us/library/ms675912(v=vs.85).aspx ) returned from DsGetDcName (http://msdn.microsoft.com/en-us/library/ms675983(v=vs.85).aspx) has a GUID associated with it, however I can find little if any information on it. I am assuming this GUID is generated at the time the first DC in a domain is created, and that it would live on for the life of the domain. Does anyone else have any inner knowledge and would be kind enough to confirm or deny my assumptions?

• What's the difference between instance and server process in Oracle database.

  - by Summer_More_More_Tea

  Hi folks: I'm now getting familiar with Oracle database. Unfortunately, I'm puzzled by the concept instance and server process. My question is what's the difference between instance and server process. What's more, what's the life cycle of instance and server process respectively? My textbook at hand is about Oracle 9i, which doesn't give me a clear explanation. Any reply will be appreciated. Thanks in advance. Kind regards!

• How to manage enterprise network of Linux machines?

  - by killy9999

  I work at the university. In my institute we have six computer laboratories used for teaching. Each lab has almost 20 computers, which gives over 100 machines total. Computers have either Windows XP or Windows 7 Eneterprise operating system. We use Symantec Ghost to manage all the computers. Each computer has a Ghost client installed, which allows to control computers over network. Every six months we restore a master image on one of the computers in a lab, update that image and distribute it over the network to all computers in a laboratory. Thanks to Ghost client this is done automatically with just a few clicks. Recently I suggested that it would be good to have Linux installed in the laboratories. The administrators were concerned that we would not be able to manage that many computers if each would have to be updated manually. The question is: how to manage such a huge network of Linux machines in an automated way? To make the description of our network more complete I'll add that all students have their accounts (about few thousand users) on a central server. These are accessed via LDAP. To use a computer in laboratory each student has to log in using his own account.

• I have a bunch of CHK files on my USB Drive that used to be my stories that I saved on there. How do I get them back?

  - by Susana

  Ok, so I am not sure why, but my USB flash drive isn't showing all of my stories that I typed and saved. It might be because I removed the USB flash drive without ejecting it safely. All of the data was there on my flash drive, I just couldn't see it. The capacity was almost full so I'm pretty sure the data was there. So, when I decided to run and check to see if there were any problems, the computer found that there were. I think it found my files, but now they are CHK files and I don't know how to get them back. Can someone please help? This is my life's work here!

• How do I make two different Google Chrome profiles?

  - by ldigas

  I have a laptop which I use for (the major part) of my work and private life, and would like to set those two apart starting with Google Chrome. So far, my Google Chrome contains my work bookmarks, logins/passwords and everything else ... which I use for work, which I use privately, which I use in my spare time (funny Youtube videos, what else :) Is it possible to define multiple Google Chrome profiles, let's say work and free-time, so one can quickly switch between them, where bookmarks, logins and so on, from one would be invisible in the other, and vice versa? Also, is it possible to put them into some directory different from the default, so one can easily backup them, when needed? If it is, could anyone describe it in simple terms, or his experiences if she/he has a better way of going about this?
