• Can't get samba to see other PCs in Kubuntu 10.04 (Lucid)

  - by MaurizioPz

  I'm new to networking. I'm trying to share a folder between to computers (both have kubuntu 10.04 installed). I'm able to share a folder with samba and can see that folder through samba on the same computer. But if I try to go on the other PC I can't see the first one. Both PCs are on the "workgroup" workgroup. I've tried disabling the firewall with firestarter can somebody help me? thanks update: here's my samba.conf http://pastebin.com/SpuES468

• Sennheiser PC360 Microphone Suddenly Stopped Working

  - by Michaelwm

  Just recently, my Sennheiser PC360's microphone stopped working. Yesterday Night, it was working 100% fine. Muting correctly, un-muting, volume boosting, etc. I woke up this morning, and got into a skype call (After not changing a single setting on my computer), and it wasn't working. I tried mumble, and it didn't work there either. After that, I checked my sound devices and found out it was plugged in, but not responding to my voice. I unplugged the headset, and it correctly showed that it was unplugged. So, a quick run-down: Sennheiser PC360 Headset suddenly stops working after a few hours of sleep. Software is up to date I can hear the mute sound when I raise and lower the microphone arm Windows Sound Device Manager shows that it is plugged in Unplugging the headset correctly shows it is unplugged Windows Sound Device Manager shows that the microphone isn't receiving any input

• Lubuntu 12.10: Icon Display Problems

  - by SlcBullseye

  First off, I would like to let you know that I am new to Linux. I finally decided to give it a try and my first project was installing Lubuntu on an old PC and using it for a media server for my PS3. So, one thing that I noticed right away is that my icons for applications, files, folders, etc...are not visible. If I move my mouse over the name of the application or file (It only works if I move the mouse up from the bottom of the name) then the icon will appear, but if I move my mouse back over any other place on the file the icon will disappear again. Also, if I open a folder sometimes an icon or two will be displayed but the rest won't, and like I said before if I move my mouse over the top of the application or file the icon will disappear. Is there any way to fix this? Is this normal? Or could it be a problem with my hardware? I never had this issue when I was running the last OS (Windows XP). Any help would be greatly appreciated. Remember, I am new to Linux so a thorough explanation would be helpful. Also, if there are any tips, tricks, references, or recommendations any of you have to help me jump in and become more familiar with using Linux that would be great! I'm very interested in taking advantage of the power Linux has. Currently I am studying computer programming so maybe one day I will be able to develop my own Linux distribution.

• How can I upgrade from Windows 8 x32 to x64 fastest & easiest?

  - by parkviewK

  I was upgrading the hardware in a family member's computer and purchased the Windows 8 upgrade for $40 from their website. Not thinking, after I installed it I realized I now have 32bit Windows on this 64bit capable machine. Did some research and it appears that the upgrade assistant just gives you whatever architecture you were uprgading from (windows 7 32bit). Question is, what is my best option here? I have already purchased a key, will this work on x64? I'm considering installing Windows 8 Preview x64 and upgrading from there, but not sure if that will work or if it will make me purchase it again.

• Leaving job, PC personal info deletion guide?

  - by bangoker

  I'm quitting my current job, and I want to make sure all my personal stuff gets whipped off the computer. I know everybody stores stuff on different places, but is there any quick guide of locations (folders) and apps that might need deletion? you know, just to be sure I erased from all the places and I don't forget any (like those were apps save stuff automatically, the data folders and such) I have erased most of my docs in My Document folder, and I am going to erase all the cookies and stored history in my browsers (opera, ie, ff, chrome) (by the way is there any tool for this?)

• windows 8 on macbook locks after 2 mins despite high performance settings

  - by Mark

  I am running my Macbook Prop as a Windows 8 machine using bootcamp and for some reason, when I leave the keyboard/mouse alone for 2 mins it locks the PC (i.e. goes to the lock screen). I have (of course) checked the power settings and I can assure you that it is not set to these settings. I did notice that when I added my work's Mail Account the computer asked me to accept some group policy settings, which I did, so I suspect that this is a group policy setting, but I cannot find it. Can someone help? P.S. I have searched these forums first, and this is different to the PC going to sleep once locked, this is locking while logged in after 2 mins. Thanks.

• Most secure way to access my home Linux server while I am on the road? Specialized solution wanted

  - by Ace Paus

  I think many people may be in my situation. I travel on business with a laptop. And I need secure access to files from the office (which in my case is my home). The short version of my question: How can I make SSH/SFTP really secure when only one person needs to connect to the server from one laptop? In this situation, what special steps would make it almost impossible for anyone else to get online access to the server? A lot more details: I use Ubuntu Linux on both my laptop (KDE) and my home/office server. Connectivity is not a problem. I can tether to my phone's connection if needed. I need access to a large number of files (around 300 GB). I don't need all of them at once, but I don't know in advance which files I might need. These files contain confidential client info and personal info such as credit card numbers, so they must be secure. Given this, I don't want store all these files on Dropbox or Amazon AWS, or similar. I couldn't justify that cost anyway (Dropbox don't even publish prices for plans above 100 GB, and security is a concern). However, I am willing to spend some money on a proper solution. A VPN service, for example, might be part of the solution? Or other commercial services? I've heard about PogoPlug, but I don't know if there is a similar service that might address my security concerns? I could copy all my files to my laptop because it has the space. But then I have to sync between my home computer and my laptop and I found in the past that I'm not very good about doing this. And if my laptop is lost or stolen, my data would be on it. The laptop drive is an SSD and encryption solutions for SSD drives are not good. Therefore, it seems best to keep all my data on my Linux file server (which is safe at home). Is that a reasonable conclusion, or is anything connected to the Internet such a risk that I should just copy the data to the laptop (and maybe replace the SSD with an HDD, which reduces battery life and performance)? I view the risks of losing a laptop to be higher. I am not an obvious hacking target online. My home broadband is cable Internet, and it seems very reliable. So I want to know the best (reasonable) way to securely access my data (from my laptop) while on the road. I only need to access it from this one computer, although I may connect from either my phone's 3G/4G or via WiFi or some client's broadband, etc. So I won't know in advance which IP address I'll have. I am leaning toward a solution based on SSH and SFTP (or similar). SSH/SFTP would provided about all the functionality I anticipate needing. I would like to use SFTP and Dolphin to browse and download files. I'll use SSH and the terminal for anything else. My Linux file server is set up with OpenSSH. I think I have SSH relatively secured. I'm using Denyhosts too. But I want to go several steps further. I want to get the chances that anyone can get into my server as close to zero as possible while still allowing me to get access from the road. I'm not a sysadmin or programmer or real "superuser". I have to spend most of my time doing other things. I've heard about "port knocking" but I have never used it and I don't know how to implement it (although I'm willing to learn). I have already read a number of articles with titles such as: Top 20 OpenSSH Server Best Security Practices 20 Linux Server Hardening Security Tips Debian Linux Stop SSH User Hacking / Cracking Attacks with DenyHosts Software more... I have not implemented every single thing I've read about. I probably can't do that. But maybe there is something even better I can do in my situation because I only need access from a single laptop. I'm just one user. My server does not need to be accessible to the general public. Given all these facts, I'm hoping I can get some suggestions here that are within my capability to implement and that leverage these facts to create a great deal better security than general purpose suggestions in the articles above.

• Dual displays not working - NVidia - Ubuntu 12.4

  - by user75105

  Graphics Card: NVidia 460 GTX. Driver: NVIDIA accelerated graphics driver (version current) I have one DVI monitor, an old Dell LCD from 2005, and one VGA monitor, an Asus ML238H from 2010 whose HDMI port broke. The Asus is plugged into my graphics card's primary monitor slot and is the better monitor even though it is VGA but my computer defaults to the Dell. This happens when I boot as well; the loading screens, the motherboard brand image, etc. are all displayed on the Dell monitor until Windows loads. Then both monitors work. The same thing happened when I booted up Ubuntu 12.4 but I did not see the second monitor when the log-in screen popped up, nor did I when I logged in. I went to System Settings/Displays and my Asus monitor is not an option. I clicked Detect Displays and the Asus is not detected. I looked at the other questions regarding NVIDIA drivers and recalled my problems with Ubuntu a few years ago and decided to check the driver. I went to Additional Drivers to install the proprietary driver and it looks like it's installed and active but I'm still having this problem. There is another driver option, the post-release NVIDIA driver, but that does not fix the problem either. Also, under System Details/Graphics the graphics device is listed as Unknown, which might indicate that it is using an open source generic driver and not the proprietary NVidia driver. But under Additional Drivers it says that I am using the NVidia driver. Any help is appreciated.

• How to combine with openvpn, dynamic-ip?

  - by asfasdv

  Dear everyone, I am currently using openvpn to surf online to bypass censorship. Let me show you the initial scenario: before openvpn is turned on: IP: 1.2.3.4 (hypothetical, checked by visiting whatismyip.com/) after openvpn is turned on IP: 10.2.3.4 (this is also checked with whatismyip.com/, I assume this is where the vpn's exit point's IP ) Situation: Once I enable openvpn, I can still ssh into this computer by sshing into 1.2.3.4, even though visiting whatismyip.com/ says it's 10.2.3.4. However, I am on dynamic IP, I run a website, and am using tools (inadyn in particular) which pings the freedns.afraid.org (my dns server) and updates my ip. The messed up part is when inadyn does so, my dns changes the ip to 10.2.3.4, which is presumably the exit point of my vpn. How do I get around this? (Note that sshing into 1.2.3.4 STILL works).

• How can I change the default keyboard layout in Ubuntu 10.10?

  - by startoftext

  Ubuntu keeps detecting my keyboard layout as Romanian. It almost always does this on a reboot and some times on waking from sleep. Some times it just randomly changes back to Romanian while the computer is on. I always set it back to "USA" in the keyboard preferences and delete the Romanian layout. What files configure this in Ubuntu? I looked in xorg.conf and did not find any keyboard settings. How can I set this to USA permanently? I have a laptop with a typical US layout built in keyboard and I also have an apple keyboard that is also US layout connected via USB. I have run other distributions on this same setup before and never had this happen.

• Recover data from SD card

  - by Paul Tarjan

  I have a 2GB kingston microSD card which is about 3 years old. I put it in a reader today in my Windows Vista computer, wrote a 32MB file onto it, safely removed it, and then tried to read it elsewhere. Nothing. Putting it back in vista it now says You need to format the disk in drive F: before you can use it. What should I do? I have access to many computers and OSes if your recommendations need that. I would be very sad if I lost all the contents of the card. Most of the data is backed up, but there are a few things that aren't. :( Doing a # dd if=/dev/sdg of=~/tmp/sd.bin gives me a 2 gig file, and grepping the file it seems like lots of my data is still there, how can I put it back together?

• How to Activate wifi in Toshiba Satellite C655?

  - by user4106

  I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc. When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed. Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them. The wifi-card the laptops brings is the (the lspci output): 03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01). It's anything in you can help me? Thanks a lot in advance! Edit Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on. In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on! One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.

• problems establishing ssh connection

  - by Superbyte

  since two days I am facing a really weird problem. I have receantly installed ubuntu server 14.04 LTS on a workstation. It has a fix IP address, which I can successfully ping from other computers in the network. But when I try to establish a ssh connection from a windows computer via putty I get some strange errors, which I cannot fix. The Problem is that putty takes a really long time trying to establish a connection. After about 10 seconds I get the following error: Network error: Software caused connection abort But when I click the Restart Session option a several times after putty shows the error message, I can login in. But now comes the other problem. When the login appears on the putty console I type in the user, but it really takes a long time until I can type in the password to login. This is what I already tried: sshd: ALL in etc/hosts.allow commented line session optional pam_motd.so in etc/pam.d/login and etc/pam.d/sshd configured the firewall with: sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT checked if ssh server is listening on port 22 UseDNS no in etc/ssh/sshd_config I hope someone can help me, because this problem is really annoying. Thanks in regard

• Powershell window preventing shutdown

  - by FrinkTheBrave

  If I have a PowerShell window (at the PS command prompt) on display it prevents the computer shutting down. i.e. if I open a powershell window and then try to shutdown the server, I get the End Program popup saying Windows cannot end this program I get the same result if I start the powershell from the start menu, from a cmd prompt and from a shortcut with -NoExit specified. Any ideas how I can get shutdown to automatically close a powershell window (if it is at the PS prompt) in the same way as it would for a CMD window? Alternatively, is it possible for PowerShell to detect when a shutdown has been initiated and therefore close itself?

• Vertically resize two windows at same time?

  - by Guy

  I love the new feature in Windows 7 where I can grab the title bar and "slam" a window against the right edge of the computer and it will size that window to the right half of the screen. I can then grab another window and do the same against the left side of the screen. Once I've done that I often find that one of those windows needs a bit more horizontal space and the other can do with less. So I grab the edge in the middle of each window and resize that window so I can most efficiently use my screen space. Problem is that I have to do this twice, once for each window. Is there a way to grab the inside vertical edge of both windows at the same time so that I can make one wider and the other smaller at the same time?

• Redirecting HTTP traffic from a local server on the web

  - by MrJackV

  Here is the situation: I have a webserver (let's call it C1) that is running an apache/php server and it is port forwarded so that I can access it anywhere. However there is another computer within the webserver LAN that has a apache server too (let's call it C2). I cannot change the port forwarding nor I can change the apache server (a.k.a. install custom modules). My question is: is there a way to access C2 within a directory of C1? (e.g. going to www.website.org/random_dir will allow me to browse the root of C2 apache server.) I am trying to change as little as possible of the config/other (e.g. activating modules etc.) Is there a possible solution? Thanks in advance.

• Is full partition encryption the only sure way to make Ubuntu safe from external access?

  - by fred.bear

  (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

• Not recognized as operating system on startup

  - by mastabruce

  I am new to Ubuntu and just decided to install it in (on my new lenovo thinkpad) in addition to my windows 7 operating system. Now, whenever I reboot the computer, it only runs window 7. I went (in windows) to Control Pannel ? System ? Advanced Settings ? Startup and Ubuntu is not even listed as a choice for operating system. I tried installing ubuntu again, but now it wants to partition the already partitioned windows folder. I can't figure out how to get Ubuntu, which seems to be installed, to run. I saw on another question here that I could be able to edit my mrb settings using EasyBCD but I can not figure out how to choose ubuntu as an operating system. My disk is already partitioned (seen from the attempted second install) so I'm pretty sure it is on the disk. Basically, how can I get ubuntu to run when I can't choose it as an operating system? Thank you for your help.

• Delete Grub and OpenSuse but keep Windows 7.

  - by elvispt

  Hi. Here is my problem. I have OpenSuse installed alongside Windows 7. Grub is the boot loader from where I access OpenSuse and Windows 7. I want to delete Grub and also the OpenSuse partitions. My first, failed, approach was to insert the Win7 DVD, choose Repair your computer and then enter the commmand prompt. I then typed "bootrec /fixmbr" and restarted. It didn't worked. Grub was still there, so was Windows7. I then tried using "bootrec /fixboot and /rebuildbcd and neither worked. So what can I do to fix this? I remember when I was using WinXP this was much simpler. I would just type fixmbr and that was it. Any clues? Thank you.

• Monitoring remote employees with screenshots and screen sharing?

  - by Lulu

  I'm looking for a way to track and monitor my online employees I hire on Elance, oDesk and such. The tool should be able to: Produce screenshots on set intervals. Provide real-time screen sharing. Preferably track computer usage while user is logged in as "working" + state which task was done in that time. If I have no all-in-one solution, I will go with RealVNC for screen sharing. But I still need a recommendation for the other things. Thanks

• Security considerations when giving access to SQL Server db for a web application

  - by rem

  I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

• Do I have a bad SD card?

  I'm trying to copy data from my computer to an SD card. After a few hundred megs, I keep getting the following errors in dmesg: [34542.836192] end_request: I/O error, dev mmcblk0, sector 855936 [34542.836284] FAT: unable to read inode block for updating (i_pos 13694981) [34542.836306] MMC: killing requests for dead queue [34542.836310] end_request: I/O error, dev mmcblk0, sector 9280 [34542.837035] FAT: unable to read inode block for updating (i_pos 148486) [34542.837062] MMC: killing requests for dead queue [34542.837066] end_request: I/O error, dev mmcblk0, sector 1 [34542.837074] FAT: bread failed in fat_clusters_flush [34542.837085] MMC: killing requests for dead queue These were all files I copied from a smaller SD card. I just want to transfer them to my new, larger card for my phone. I tried the same experiment with different files on a different machine and the card failed again. Reading data from the old card went fine. My systems are older and the new SD card is new (16GB Class 4). Could this be that my computers are too old? Is there a definitive test to verify if my SD card is bad?

• Motherboard with embedded hdmi problems with Windows 8 Consumer Preview (64bit)

  - by duluca

  I'm specifically referring to GIGABYTE GA-E7AUM-DS2H LGA 775 NVIDIA GeForce 9400 HDMI Micro ATX with a Core 2 Duo chip. This computer is connected to a Sharp Aquous TV using HDMI. It all worked fine with Windows 7 64 bit. In Device Manager I see GeForce 9400 and have installed the latest NVidia drivers (295.73 WHQL). However, when I click on the change the screen resolution to 1920x1080, I see that Windows 8 thinks that it's using some other graphics card with Microsoft Basic Display Driver. This was made clear, when I tried to launch the NVidia tools and it claimed that the current monitor (in this case my TV) wasn't attached to the GeForce 9400 card. In Device Manager, there's a "Coprocessor" and "Unknown device" without drivers, but I've no idea what they are. I've run the original CD that the motherboard came with no success. Any ideas?

• Ubuntu 11.10 very slow compared to Windows

  - by Patrick

  I'm new to Ubuntu/linux. Since my PC is very old and not very fast with Windows 7, I decided to give Ubuntu a try, so I downloaded and installed Ubuntu 11.10 today. When I first started it, I had bad 800x600 resolution and it was very slow and annoying. So I installed a driver for my graphic card and now everything looks very nice (1280x1024).But I think it's still far slower than Windows 7. I tried to run in Ubuntu like a few people suggested on the forum but if I log in I get a black screen saying something like "this video mode cannot be displayed". I get that same screen when booting Ubuntu btw, but after about 15 seconds it disappears and just starts Ubuntu. I also installed other drivers for my graphic card but everything stayed the same. I noticed that i.e. when I open Firefox or system settings it takes about 5 seconds till it opens (while Windows 7 takes under 1 second to start i.e. Chrome) and when I do this my CPU usage gets to 100% for a short time. Computer specs: Memory: 2GB RAM Processor: Intel Pentium 4 2.8GHz Graphics Card: Nvidia GeForce 6800 400MHz. I read on various forums that 11.04 works flawless on many PCs, where 11.10 is very slow. Should I install 11.04 or could anybody help me with this problem?
