• Cannot ping any computers on LAN

  - by Timothy

  I havem't been able to find a straight forward answer on this yet. I'm hoping people here are able to help! Keep in mind that I'm a complete beginner at this - this is the first installation i've done for any LINUX systems ever so please keep that in mind when answering this question. We are a complete Windows shop, using nothing but Microsoft products but looking into the value of OpenStalk however have been having problems getting Ubuntu Server installed and speaking to the network. The machine is getting an IP address which is telling me that some sort of DHCP activity is working but I'm not able to ping any computer on our network as well as not able to connect to the internet. Every time I try to ping i'm getting; Destination Host Unreachable I've tried using modifying the resolv.conf file with our static details to match my Windows 7 machine still with no luck. Even tried disabling the firewall on Ubuntu Server 11 and no luck. Any ideas? Please let me know if there is any information you need from the server and I'll post up.

• apt-get failed install of libg15, all package management is failing

  - by Stifle

  I was trying to get my Logitech G510 keyboard's back-lights working so I went into the Synaptic Package Manager and marked LibG15, G15daemon, and all the other associated packages. Synaptic reported a failed install. Now all Package management is failing due to libg15 being "halfway installed." Some commands I have tried to fix the problem follow. . . root@bt:~# apt-get upgrade Reading package lists... Done Building dependency tree Reading state information...

• Is there such thing as a portable database that runs easily OsX and Windows?

  - by Jean-Philippe Murray

  I need to make a small database for a project at school (not computer related at all, I'm indexing and categorizing paper documents of a research projet). The thing is that in september, my semester is over and other students will have to taker over the project (and so on, for every semester!), so I'd need something that would be free and OS agnostic (or at least OsX/Windows) so it would easily be given to the next students on the project. I was thinking about a WAMP running USB key that would have a MySQL / HTML interface, but it will become locked to the OS I choose first. LibreOffice and the likes will be an option in the end if I don't find anything truly portable. Anyone has a solution in mind?

• wifi routers and concurrent devices

  - by Joelio

  We have a Linksys WRT54G WiFi router in our office which was working great when we had 5-6 folks. Now on peak days we have 10-15 people, each with a computer, smartphone, etc, and an ooma VOIP device. On average 1-2 times a day I need to go hard reboot the router, and sometimes the border router (Cox-supplied device). I assume this is just because the router cant handle this many concurrent users. So my question is can these consumer routers handle this kind of load? If not, would adding more devices solve the problem, and how close proximity can I put 2 routers without having interference problems (our office area is not that big physically)?

• Reading Data from the Entire Surface of a CD, DVD

  - by Hypertext

  Is it possible to retrieve data from the entire surface of a compact disc. Suppose a CD written with 300MB of data where the remaining 400MB is blank. Normally, computer doesn't bother with the 400MB region when reading it because the filesystem ends at 300MB. But, is it possible to make the CD drive retrieve data from the rest of the surface. Idea is to retrieve something from outside the image. If possible, true it might return useless 0s or 255s data. But, is it really possible?

• Possible to install Xmonad on Ubuntu separate from Gnome?

  - by Kurtosis

  I just downloaded Xmonad from the repository on my Ubuntu 10.04 box, but when I log out and try to log back in using Xmonad instead Gnome, it doesn't work. I just get the login screen background image and a mousepointer, and nothing else. Right-clicking does nothing, no menus or anything. Key combo's like Ctrl-X, Ctrl-Z, and Ctrl-Alt-Delete do nothing either. Left the computer in this state for 30 minutes while I went to the grocery store, but it was still hung when I returned and I had to hard-reboot it. A Google search returned a few sites showing how to configure Xmonad to work with Gnome, but I'm afraid to try this since I don't want to risk borking my Gnome installation, at least not until I've had a chance to learn Xmonad a bit. Is it possible to run Xmonad independently of Gnome? If so, anyone have any idea what might be wrong and how to fix it?

• Going on 15 months for me...

  - by Ratman21

  About 5 face to face interviews, 4 telephone ones and except for the two weeks Census Job. But, after 15 months looking for work, I am still with out a JOB. What is wrong here or with me? Let’s see, hard worker (check), self motivated to do well on a Job (Check), Certified CompTIA A+, Security+  and Network+ Technician (Check), 20 + years experience in “IT” (CHECK), in good health, in 20 years of work only 15 days off due to health issues (Check), 18 years experience as technical Help Desk support (Check), can still work better than younger personal (Check), Strong trouble shooting skills for software, computer hard ware and circuit issues (Check) and Multiple software languages (Hey I have done some programming) Check. Hmm I don’t see any problem with me (of course I could have missed something, please let me know if you see what I am missing).    Now as to what have I been up to since I last blogged. The same things of course, Job hunting, job hunting and study.   I have set up sim of my home LAN and will be adding a wireless print server to the sim and in real life, soon.  I was able to pull up and copy the examples of Cisco router commands that I had on my old lap top, to my newer PC. Every time I used a new command while working the NOC on my last job.   I would cut and past a copy of the command on the router (and what it did) I was working on.  Along with notes on the problem and commands use for same router. I used these to make documentation for on how to handle these types of issues, for the other Operation Techs. My old notes are helping me in studying for the CCENT test.    As to Love Dare, I think it will take more like 40 weeks, than the 40 days of the book. Yes I am making progress, slow but, it is progress. I will have more on that in my next blog.

• Unix: Sync directory with FTP or SFTP directory

  - by Svish

  I have a website on my local computer running Mac OS X. I am wondering if there is any built-in command that I can run in the Terminal that will upload that website to my webserver either through FTP or, if possible, SFTP. Installing new commands through MacPorts is also a possibility. A big bonus would be that it only uploaded the files that needs to be updated and not everything else. It would also be nice if I can tell it to delete the files on the server that no longer exists locally once in a while. Any good tips?

• Monitor sleep in Windows XP does not work. Is there an add on to force it?

  - by bert

  I have an EEE box with XP Home and a DVI connected TFT, and it does not sleep the monitor. It only starts working after I go to the energy control panel and turn it off and on again. Then the timed sleep works for the current session of computer use. After a shut down and boot next day, sleep does not work again (it is still set in the preferences however). What can hold the sleep function from working? Are there issues with Skype or MSN? Is there a utility to be less critic to processes interrupting sleep and offer a more reliable monitor sleep function for XP?

• Ubuntu Gnome 14.04 Instal Nvidia drivers

  - by user3524668

  I have been looking all over the web, and tried every suggestion I found to get the nvidia drivers working on my computer with Ubuntu Gnome 14.04, with no luck. Every time I install a driver or choose to use the driver from addition drivers, when I reebot, I cannot log in again. It gets stuck at the logo screen. I need to go to the ALT + CTRL + F1 to purge all nvidia traces so I can get back. Is it possible to install the new nvidia drivers? I just upgraded from 13.10 to 14.04, I have an Asus N550VJ which has hybrid graphics with Intel 4000 / Nvidia 750M What Im looking for is to try the primus functionality to disable the discreet card and enable it whenever I want to play or run heavy graphic stuff. When I was in 13.10 I was using bumblebee, but, since, the nvidia prime is supposedly mature enough, I wanted to try it. Is this possible for Ubuntu Gnome 14.04. I read there was a bug with gdm, but also, saw that it was already fixed. Thank you very much for your help. Im not that well versed in linux.

• Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

  - by Al Rowe

  Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

• Will I be abled to access 2nd HDD from dual-boot

  - by Ruben

  I'm planning to have a dual-boot on my computer. I have 2 physical hard drives, one 500GB and one 2TB. What I want to do, is have a dual-boot setup (2 partitions, both 50 GB) for Windows 8 and Windows 7. But will I be able to access the 3rd partition on the disk, or the other disk from both OSs? In this case, it would be really useful to access files and install programs, because I could use them on both OSs, as long as I have the same registry keys.

• Copssh, how to add users?

  - by Ken

  I installed copssh on Windows Vista (64-bit) here, and the installation seemed to go fine. It requires you to explicitly add users to log in, which is fine, so I opened the COPSSH Control Panel (really just an app), went to the Users tab, clicked Add, Forward, and the "User:" popup is empty. The "Domain:" popup has exactly one entry: my computer name. The "Documentation" shortcut in the start menu group is broken, but I found the folder it's supposed to point to, and I only see docs for command-line tools (which I'll investigate next). Is there something I'm missing? Is the COPSSH Control Panel just plain broken?

• Ubuntu: Is there a good tabbed PDF viewer?

  - by Frank

  Is there a good non-bloated PDF viewer for (Ubuntu) Linux that supports tabs? I don't want to use Acrobat Reader because it is slow and takes much memory, and my computer isn't the fastest. I know the alternative readers evince and foxit, but they don't support opening different PDF files in tabs. (foxit has that feature on Windows, but the Linux version 1.1, which I just tried, doesn't have it.) For evince, I know many people would like this functionality, but they get ridiculed by Ubuntu people (see here), who say that tabs are the task of a window manager. If that is the case, how can I put all evince windows into one in GNOME?

• Windows Server 2012 - SSL Cypher Suite Order Not Long Enough

  - by Sam

  I want to re-order the cypher suites on our new Windows Server 2012 box to help mitigate the BEAST vulnerability for our clients. I went to Local Group Policy => Computer Configuration => Administrative Templates => Network => SSL Configuration Settings, opened SSL Cypher Suite Order, enabled it, and copied the values from the SSL Cypher Suites textbox. I pasted them into notepad, re-ordered them, then copied+pasted them back into the SSL Cypher Suites textbox. However, the box isn't long enough to hold them all, despite the fact that the length didn't change. I would have to drop the last 3 cyphers (SSL_CK_DES_192_EDE3_CBC_WITH_MD5,TLS_RSA_WITH_NULL_SHA256,TLS_RSA_WITH_NULL_SHA) in order for it to fit. Should I just drop them? Other ideas?

• How can i get my KVM switch to work? (win7 & ubuntu 10.10)

  - by Will W.

  i bought a KVM switch and i'm trying to use it to have it connected to my main PC (win7) and my new machine i just installed ubuntu on. I hooked it up properly, and tried using it. It worked when switching from the win7 machine to the ubuntu one, but after the (1st and only) successful switch, ubuntu just didn't seem to recognize my mouse or keyboard. Basically when i tried it the easiest was to explain what happened was it only worked with Win7. When i switched over to ubuntu by doing a [scroll-lock] [scroll-lock], my keyboard and mouse were not recognized. However, the lights on the keyboard and mouse did work when on ubuntu, but they didn't function, and since keyboard wouldn't function, i couldn't do a [scroll-lock] [scroll-lock] to switch back to the win7 machine. So i was basically locked in to ubuntu with no mouse or keyboard, and i had to unplug the keyboard/mouse usb's and d-sub to plug the monitor d-sub back into win7 computer to type up this thread and google the issue. Seems some people have had this issue before but i couldn't find a fix... I am 80% sure it has to do with drivers... but there isn't any for KVM switches, at least not this one also i never was unable to find ubuntu drivers/firmware for my mouse and keyboard (Logitech G15 and Razer Deathadder 3500). I don't know how to fix this, perhaps someone super-savvy could write/code a script or work-around or something? I really need to get this thing working, my back is getting sore from bending over and plugging in / unplugging usb/monitor/usb/monitor/usb/usb over and over again lol... and i really would be sad if the constant plugging unplugging of the usb's or the d-sub port would over time damage the ports... i don't want that... There has to be some way to get this working.. Can anyone help? The KVM is a IOGEAR GCS632U Win7 x64 Ubuntu 10.10

• Windows 7 connect to Lion file sharing

  - by McKvack

  Trying to access my Mac from a Windows 7 computer, I fail with the infamous error 86 incorrect password. Now this appears to be a well-known problem with countless threads on the internet giving as many "solutions" as there are discussion threads about it (mostly ranging from installing third-party commercial samba servers, to switching to some other protocol, to compiling a plain-vanilla Samba installation - the latter which I will probably do when I give up this :) ) I am stubborn, and I believe there must be some problem here that can be solved or worked around, but there is surprisingly little detail about this problem. It appears to have something to do with a mismatch of authentication methods. Trying to run samba in debug mode: sudo /usr/sbin/smbd -debug -stdout gets me this output when trying to access it from Win 7 ... smb1_dispatch_one [smb_dispatch.cpp:377] dispatching SMB_COM_SESSION_SETUP_ANDX smb1_dispatch_session_setup [session_setup.cpp:261] FIXME erase existing sessions log_gss_error [gssapi_mechanism.cpp:97] gssapi: gss-code: Miscellaneous failure (see text) log_gss_error [gssapi_mechanism.cpp:113] gssapi: mech-code: unknown mech-code 22 for mech unknown What is the problem here, and how do I fix it?

• Intel Pentium 4 vs. Faster Celeron

  - by Synetech inc.

  A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two?

• DualLayout OpenSourceFood demo site installation instructions

  - by svdoever

  We released DualLayout which enables advanced web design with the power of SharePoint. DualLayout and a demo site can be downloaded from the DualLayout product page. This blogpost contains detailed instructions on installing the demo site. The demo site is based on the site http://opensourcefood.com. The demo site requires internet access because it still links to pages and resources of the real site. Execute the following steps to install the demo site: Copy the OpenSourceFoodDemo.zip file to your SharePoint Server 2010 Make sure that the zip file in “unblocked”, otherwise files are assumed from other computer (right-click on zip file, press “Unblock” button if available) Unzip the OpenSourceFoodDemo.zip to a folder of your choice (c:\OpenSourceFoodDemo) Open the SharePoint  Start->Microsoft SharePoint 2010 Products->SharePoint 2010 Management Shell Change directory to the unzip folder (cd c:\OpenSourceFoodDemo) Start install script: .\InstallDemoSite.ps1 Answer the questions, default values in most cases ok. A little guidance: Question: Give credentials for the account that will be used for the application pool Answer: use for example same account as used for the application pool of your SharePoint site (lookup in IIS Manager) Question: Give credentials for the account that will be used for the application pool Answer: Use same account you are currently logged in with The demo site is made available through a backup and restore. The SharePoint Server 2010 installation must be patched to a level equal or higher to the update level on the SharePoint Server used to create the backup. If you get errors with respect to restore check http://technet.microsoft.com/en-us/sharepoint/ff800847.aspx for downloading the latest cumulative update.

• What is Mobsync.exe? Assuming I don't need it, can I disable it in Windows 7 without ill side effect

  - by Chris W. Rea

  I'm running Windows 7. Occasionally when I resume my computer from standby, it seems to wait 20-30 seconds or so before giving me full control back. In an attempt to diagnose why, I've been watching what's going on using the awesome Process Explorer. One of the processes I've noticed being started during that hiccup time is Mobsync.exe, described as "Microsoft Sync Center". Sync? Sync what? So, what is Mobsync.exe used for, exactly? Assuming I don't need its functionality, can I disable it in Windows 7 without ill side effect? If so, what's the best way to disable Mobsync.exe?

• connect to ssh server thru 80 via HTTP proxy?

  - by im_chc

  Hi, Please help: I want to connect to my ssh server at home However, I'm behind a corporate (CORP) firewall, which blocks almost all ports (443, 22, 23 etc). But it seems that 80 is not blocked, coz I am able to surf the web after I login (i.e. IE sets to CORP's proxy server, and start IE - displayed CORP intranet portal - type in google.com - dialog pops up for userid + pwd - login successful, and surf without restrictions) My ssh server listens at 443. My question is: Is there a way to connect from a computer behind the CORP firewall to the ssh server thru the 80 port, with the ssh server still listening on port 443? Changing the ssh server to listen to port 80 is not an option, coz my home ISP blocks 80. Can I use a public proxy which listens at 80? After some research on google I found that there is something called "connect to SSH thru an HTTP proxy" using the Cockscrew software. Is it useful? Or is there some other way to solve the problem?

• If I install Ubuntu 12.04, will it recognize all of my RAM?

  - by user91048

  I have a question that's been bugging me since a long time. A friend of mine told me that when he had Ubuntu 11.10 installed the OS only recognized 3.4GB instead of 8GB. In the next week I'll be buying a new computer and I'll have 8GB of RAM, does the Video Card need to have it's own video memory for the OS to recognize the RAM entirely?. If you could give me some advise on how to configure my PC before I buy it it would be great. Thanks. Tengo una duda que me ronda de hace tiempo. Un amigo mio me comento que con ubuntu 11.10 tenia 8 gb de RAM y que solo le reconocia 3.4. Dentro de unos 5 dias me comprare un ordenador nuevo a base de componentes y voy a meterle 8 gb de RAM. ¿Hace falta que la tarjeta gráfica tenga Gb dedicados para que el sistema me reconozca la RAM entera? Si podeis darme algunos consejillos sobre como configurar el PC antes de comprarmelo para que ese problema no me pase, Muchisimas Gracias.

• Using Remote Desktop, connect to a Windows 7 domain user account without first logging on locally?

  - by calavera

  I have a dell laptop (henceforth we'll call this the server) running Windows 7 Enterprise. The server is part of my company's domain. My primary user account is a domain account. When I am at home and not connected to the domain, I prefer to connect to the server using Remote Desktop Connection from my MacBook Pro (we'll call this the client). The problem is, that if I do not physically login to the server, I am unable to connect to it using RDC from the client. I have a local administrator account on the server, and connecting to it via RDC works just fine. I had a feeling that the Mac RDC application was not giving me the full story, so I attempted the same procedure from a Windows 7 client. When trying to login, I get this message: So basically, If I logon to the server physically with my domain user and lock the computer, I can then successfully logon from the client. Otherwise, I am unable to connect.

• Having trouble getting startup scripts to work in Server 2003

  - by Az

  Thanks for taking the time to read this. I am having trouble getting my startup scripts to run correctly on the domain I am administering. Before anyone gets upset and says "go read xxx article from microsoft",... I have. I am simply missing something or not understanding it properly. I understand how to assign the script, what I am curious about is where exactly it should be placed in the Windows folder structure. I have been able to get them to work by creating a share folder called "scripts" and pointing to that exact unc pathname IE \servername\scripts\xxx.bat. However, I would like to do it properly, would someone please tell me where they should be placed in Win2003 server, and what the path name should be when assigning a group policy to do something that applies to computer specific properties? Your assistance is very much appreciated by a junior admin trying to learn some new tricks!
