• Dell Inspiron 1501 battery no longer "recognized"

  - by mwalling

  My parents were on vacation last weekend and franticly called me saying that they couldn't get their Inspiron 1501 to boot anymore without the BIOS whining about the battery. Before this happened, they said the "battery went dead with negligible pre-warning". On bootup, the computer says: WARNING: The battery cannot be identified. This system will be unable to charge this battery. With options to enter the BIOS or continue booting. I got to look at the machine last night. The battery still holds a charge, and will recharge. Windows detects it as a DellPY9617 battery manufactured by "DynaPack". I didn't get the BIOS revision, but the machine's ship date was 7/21/2007. The recommendations I could find on the internet varied from "discharge the battery completely" to "your computer is too old" to "update the BIOS", and wanted a more specific answer before doing something drastic.

• Failing RAM, or something else?

  - by Thanatos

  I have a IBM Thinkpad T43, currently running Windows XP. Programs were crashing, XP was blue-screen-of-deathing, (more than usual) - it was basically unusable, but I couldn't get any informative error out of XP. I booted Ubuntu off a thumbdrive, which made it to the desktop, but as soon as I started to try to do anything, X segfaulted, along with several other services, followed quickly by kernel warnings and a kernel panic. I'm currently running Memtest86+ on this machine, which is spitting out numerous errors. (16k over 3 passes, and counting) The failing areas are numerous, and look something like this: 0001055da4 - XX.X MB, etc. The addresses that fail seem to cluster around 0-20 MB, 250MB, and, more rarely, 750MB, 1000MB, and 1200MB. However, a lot (but not all) of the failing addresses that I've seen end in XXXXXXX?da4 where the ? is a 1 or a 5. The machine has two sticks of RAM, one 512MB, one 1024 MB, the 512MB mapped to the lower addresses, the 1024 MB stick following. Is this indeed RAM failure, or should I consider other things before purchasing more RAM?

• WSUS moved how to reset the database and check the folders?

  - by Matthew Zielonka.co.uk

  I have a bit of a problem with a WSUS box, I backed up the WsusContent folder (about 180 gig) to a second machine, wiped the first machine then realized I don't have the database folder! I can not find any articles / guidance on this, I have re installed WSUS however it does not find the other files which where previsously downloaded (I guess the database being the reason). If I do a reset it will force it to download the ones it has again I guess and does not check what is still to be downloaded? Sigh... love / hate WSUS at the moment with a passion :) Thanks for any help.

• Linux - Network Sharing a local NTFS usb drive

  - by Jonathan Rioux

  I have an external hard drive formated in NTFS which I would like to be able to access by the network. I want to make a network share out of it. I also have a Debian machine running in my house and I then got an idea. I want to plug in my external hard drive (usb) into my Debian machine, and make a windows share with it, maybe with Samba, so I will be able to access it from my Windows 7 laptop and see it as a network share. Additionally, how can I restrict specific folders of that network share, and allow only specific folders to specific users? For instance, I would like to give my girlfriend access to a folder of her name so she can put her files and so she wont be able to see the stuff in my folder...

• Cannot get script to run at startup (tried all the simple answers)

  - by Carey Head

  I have Ubuntu Desktop 12.04 LTS running great on an older Acer desktop. I want to use this machine as an in-home server for hosting Minecraft. The command to start the Minecraft server is java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui and that works great when I cd into the correct directory and execute the above. I created a script to do this: #!/bin/bash cd /home/myuser/minecraft-server1 java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui & cd /home/myuser/minecraft-server2 java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui & exit 0 I made this .sh file executable, and it too runs great when I start it manually from the terminal. The problem I'm having is getting these to execute at startup. I have my user account on this machine to auto login. I have tried the following: Adding the following to "Startup Applications" : sh /home/myuser/myscript.sh (Nothing happens on reboot) Adding the same to /etc/rc.local (Nothing happens on reboot). I even tested this one by running /etc/rc.local from the terminal, and it executed great. Just not at boot/auto login Added the lines from the script directly to rc.local (Nothing happens on reboot). I can't help but think that there's something I'm missing. The script executes great when run manually, but will not run at boot/auto login. Many thanks in advance.

• Can't connect nonlocally after 12.10 upgrade

  - by user101815

  I've just upgraded one of my systems from 12.04 to 12.10. Now I can't connect on that system beyond my local network. Connections within the local network seem to work fine, and I can make nonlocal connections from other machines (like the one I'm asking this question from). I suspect that some routing information has been messed up, but I don't know where to look for it. It's not a nameserver problem -- pinging outside sites by their IP addresses doesn't work either. I have another laptop next to this one, also running Kubuntu 12.10. On the one that can't connect, arp produces no output. On the other one, it produces 192.168.0.1 ether 00:23:69:fa:ce:ae C wlan0 On the working machine, the output of netstat starts with some tcp entries. On the nonworking one, those entries are absent. I asked this question on the Ubuntu forum but haven't gotten any answers there. One further complication: since the troublesome machine has no outside connection, it's extremely difficult to download anything to it. For what it's worth, "ping 8.8.8.8" produces "connect: Network is unreachable". Update: after a lot of fiddling, I have my external world back. I don't know what the key action was, but the first indication of progress was that "ping 8.8.8.8" worked. At that point I still didn't have a working nameserver, so external URLs didn't work. But I did this (based on an online post, of course): sudo dpkg-reconfigure resolvconf and answered Yes to all prompts. That did the trick!! Apparently my problem was unique, or close to it, since I couldn't find any online references to it: local net working, remote net not working, including explicit IP addresses. So I suppose that if no one else has this problem, no one cares about the solution!!

• What to do about "system running in low-graphics mode"?

  - by ubuntubabe

  My Dell which was 5 years old suddenly karked it and I had the "low graphics" black screen and useless dialogue box. As I believed it was a dead graphics card I went out and bought a brand new machine. I put aside the new machine and tried again in vain to open the Dell. I eventually got to the command line via Ctrl+Alt+F1. I logged into my account from there, and simply started a series of sudo apt-get remove of various softwares that I knew were installed on my PC (software without any great consequence like Google earth, tweak, Skype etc). Lo and behold after a sudo reboot my computer was fine again! So now I have 2 computers. BUT one week after buying the other one and installing 12.04 because I love Ubuntu, the SAME PROBLEM arrived! I once again deleted Google earth, Skype, and did a sudo reboot and everything worked as before. I think there is a bug or something in 12.04 as this problem has never arisen with any other versions of Ubuntu.

• Duplicate Name Exists error from virtual PC with NAT network configuration

  - by Phred

  Whenever I change the network configuration to NAT for a virtual machine running under Virtual PC 2007, I get "A duplicate name exists on the network." error. There is no other machine on my network with this name and running the VM in any other network configuration doesn't cause this error. This seems to be a common problem with Virtual PC 2007 based on a google search but no-one seems to have a solution to it. So far, I've discovered that turning off NETBIOS over TCP causes the problem to go away but I need to join this VM to a domain and you can't do that if NETBIOS over TCP is turned off.

• Connect to my virtualbox mysql server

  - by WebweaverD

  I wonder if someone here could help me, this is my set up: I am on a windows 7 machine running a ubuntu virtualbox as my local web server and database server (mysql). I have just got hold of a copy of Komodo which i am running on my windows machine which I would like to hook up to my database. The fields it needs are hostname, port, socket, username and password. I know the username/password but am unsure how to find out what to put for the other fields. The ubuntu vb has an ip of 192.168.0.10, which is in my hosts file as http://swishprint.dev I hope I have asked this in the right place, any help much appreciated.

  Hello I've a HP Pavilion DV4 with windows Server 2008 R2 enterprise. My system is connected to a domain. I login using my domain account. I am the administrator for the local machine. But I'm getting access denied everywhere (file system, running commands, using visual studio..literally everywhere..) in my machine. What could be the problem? Any ideas? Please tell me if you need more information as I'm just a developer with less knowledge in system administration.

• Solutions for "Maintenance Mode"

  - by Ka Lyse

  Given a web application running across 10+ servers, what techniques have you put in place for doing things like altering the state of your website so that you can implement certain features. For instance, you might want to: Restrict Logins/Disable Certain Features Turn Site to "Read Only" Turn Site to Single "Maintenance Mode" page. Doing any of the above is pretty trivial. You can throw a particular "flag" in an .ini file, or add a row/value to a site_options table in your database and just read that value and do the appropriate thing. But these solutions have their problems. Disadvantages/Problems For instance, if you use a file for your application, and you want to switch off a certain feature temporarily, then you need to update this file on all servers. So then you might want to look at running something like ZooKeeper, but you are probably overcomplicating things. So then, you might decide that you want to store these "feature" flags in a database. But then you are obviously adding unncessary queries to each page request. So you think to yourself, that you will throw memcached in to the mix and just cache the query. Then you just retrieve all of your "Features" from memcached and add a 2ms~ latency to your application on every page. So to get around this, you decide to use a two tier-cache system, whereby you use an inmemory cache on each machine, (like Apc/Redis etc). This would work, but then it gets complicated, because you would have to set the key/hash life to perhaps 60 seconds, so that when you purge/invalidate the memcached object storing your "Features" result, your on machine cache is prompt enough to get the the new states. What suggestions might you have? Keeping in mind that optimization/efficiency is the priority here.

• Dell Inspiron 530 - SSD Worth it?

  - by DrFredEdison

  I'm going to be upgrading my Dell Inspiron 530 (2.0 Ghz Intel Dual Core CPU, 3 GB RAM) to windows 7 soon, and rather than backup and reformat my existing drive, I'm planning on getting a 2nd drive to replace my current primary, and moving it to a secondary. Thus, this seems like an excellent time to get a solid-state drive, if its going to be worth it. As far as I can tell this machine has a SATA-I controller, and I'm unsure if I'll see a noticeable performance increase with an SSD without going to SATA-II. So I have a three part question here given all that: Will spending the money on a SSD be worth it if hook it into a SATA-I controller? Is it reasonable to upgrade the controller on this machine to a SATA-II controller? Given that this PC is kind of old to begin with, am I better off performance wise to just stick with a faster HDD?

• Disable RDC Welcome Screen in Windows 2008 R2

  - by mikebridge

  Is there a way to disable or bypass the "Welcome" screen I see when I'm using RDC to log in to a machine using saved credentials? I have startup task which launches an RDP session automatically to localhost when the machine boots. This works, except that the remote desktop window stops and waits for an "OK" on the Welcome screen: MACHINENAME-A.B.C.D(Server ID:Console 0) Welcome [OK] This screen is preventing me from automating this login. Is there any way to get around it? EDIT: Here's the command line I'm currently using to launch it: start /min C:\windows\system32\mstsc.exe c:\rdp\ServiceRunner.rdp

• Creating New WebSphere cluster

  - by user154561

  I need to improve WAS perfomance and want to make cluster. I have two separate machines with WebSpphere 7 on it. As I see to do this, I need to add node from my second (remote) WAS to the first one. I try to use "Add node" from console, but without success. It can't find host when I try to execute it. WAS help says about host: Specifies the host name or IP address of the node to add to the cell. A WebSphere Application Server instance must be running on this machine. Does that mean that I cannot add node from a remote machine with "add node?"

• Sharing VPN access between two computers on the LAN

  - by Axelle Ziegler

  I have VPN access to several machines in my office from my home machine. I'd like to be able to access those machines from another computer on my LAN, without setuping a second VPN access. Both computers are Windows 7 machines. Is there a way for my "main" computer to share its VPN access to another machine on the LAN? How would one setup this share? I don't think "simple" Internet connection sharing fits my needs because: My LAN already has its own DHCP/Router to access the Internet, and I'd like to keep it this way I can't access the Internet through my VPN connection

• Generic Windows 98 USB Drive drivers?

  - by Electrons_Ahoy

  I've got an old Win98 machine that I'd like to pull some data off of. (Tens of gigs of data, actually.) The machine still runs fine, but due to the age, it doesn't have a cd burner, and the pre-NT networking won't connect to SMB shares without a fair amount of wrenching on the registry that I don't really want to do. What I really want to do is plug in an external USB hard drive and copy the files. But - Win98 didn't ship with generic USB drive drivers, and external drives don't ship with them these days. Can anyone point me at a reputable generic driver I can install?

• Windows 7 Intermittent Connection Issues (Continuously "identifying")

  - by andrewktmeikle

  I have an issue solely with my desktop windows 7 machine on my network (the network has multiple different devices, on the same and different operating systems) and the issue is that irregularly, although sometimes frequently, I briefly get disconnected from the internet (briefly is for around 5-10 seconds). However, I never loose the bars on the wifi thing, eg I don't get the yellow triangle, but it goes to the identifying stage and then reconnects. The reason I noticed the problem was when I was streaming music it would stop and I would refresh the page and it would start working again ( turned out it was because it took that amount of time to get connected again). So my question is, what would cause the intermittent issues and start the "identifying" process again. I don't think its my router, because no one else is having problems, so the other option is that its a problem specifically with my machine. I'm connecting to a Netgear DG834GT router, and I'm using a Edimax Wireless-N150 USB Adapter. Anyone have any ideas?

• More than one XP Mode virtual machines okay under Win 7?

  - by kousen

  I really like the Windows XP Mode virtual machine that comes with Windows 7 (once you download the integration components). I teach technical training classes, and having a machine configured for the classroom is very helpful. My question is, can I configure more than one? The documentation suggests you can make multiple virtual machines, but I can't tell if I can have multiple "Windows XP Mode" VMs. It can't be as simple as configuring one, then just making a copy of the primary disk file, could it? I only plan to run one at a time, but I'd like to configure multiple different VMs for different classes, all running XP if possible. Thanks for any help!

• UTF-8 locale portability (and ssh)

  - by kine

  I spend a lot of my time sshed into various machines, all of which are different (some are embedded, some run Linux, some run BSD, &c.). On my own local machines, however, i use OS X, which of course has a userland based on FreeBSD. My locale on those machines is set to en_GB.UTF-8, which is one of the available options: % echo `sw_vers` ProductName: Mac OS X ProductVersion: 10.8.2 BuildVersion: 12C60 % locale -a | grep -i 'en_gb.utf' en_GB.UTF-8 Several of the more-capable Linux systems i use appear to have an equivalent option, but i note that on Linux the name is slightly different: % lsb_release -d Description: Debian GNU/Linux 6.0.3 (squeeze) % locale -a | grep -i 'en_gb.utf' en_GB.utf8 This makes me wonder: When i ssh into a Linux machine from my Mac, and it forwards all of my LC_* variables with that 'UTF-8' suffix, does that Linux machine even understand what is being asked of it? Or is it just falling back to some other locale? In either case, what is the mechanism behind its behaviour, and is it dependent on any particular set-up (e.g., will i see the same behaviour on a BusyBox-based system as on a GNU-based one)?

• Error code 2503 - Cannot install software on Windows 7 (64Bit)

  - by SixfootJames

  A short while ago, I had my hard drive die on me and at the same time my 1Tb backup drive! I took it back to the guy I bought the PC from and although the backup drive could not be recovered, he managed to get my machine working again by making a minor change in the BIOS which then got it out of that continuous loop it found itself in after multiple BSOD episodes. Everything seems to be working fine but yesterday when I tried to save something from Google Chrome, I got and insufficient permission problem and when I try to install software, I get an error of 2503. I have already followed the suggestions here but none of this worked for me. Any suggestions would be appreciated. EDIT: This started happening after I tried running a number of tests to get the machine working, including a previous restore point.

• Ubuntu + SSL ports + AVAST

  - by jurajvt

  I have an interesting problem with communication via standard SSL ports. Fresh installed Ubuntu 14.04 server + Postfix + Dovecot, SASL authentication provided by Dovecot, self-signed certificate generated trough the Dovecot script mkcert.sh. Redirected ports on ZyWALL USG 200. I can send and receive e-mails from outside with standard ports 25 and 110, but not over 587. I am connecting to my server from machine with Windows 8.1 + VMWare Player + Ubuntu 14.04 Desktop + ssh. On Windows host I have installed Avast! antivirus. When I am trying to telnet from virtual machine to server over 587, it refused connection. But when I turn on Avast! it let me in to message Connected to... Same with nmap. When Avast! is turned on it is show me all SSL ports. When I turned it off, only standard ports appeared. OpenSSL shows me CONNECTED(00000003). But outside virtual machine directly in Windows 8.1 using nmap with zenmap there are not opened SSL ports in both Avast! states. From other external linux machines are problems with touching SSL ports same - refused. I have turned on submission in master.cf and 587 port is correctly listening on 0.0.0.0 in process master.pid which belongs to Postfix. I can telnet, or nmap over port 587 to my domain directly from server. Other ports like 995, 993 are OK on localhost, too. It is true, that I can't send emails via 587 anyway (Avast! turned on/off), but I can see ports opened. It is possible, that I have simply bad certificate and Avast! has right one, so with turned it on I can see opened ports? EDIT: To be more clear, I can't see or using port 587 everywhere from outside (tried Thunderbird, telnet, openssl, nmap, putty, swaks; both from Linux or Windows machines) and that is my problem. It was only by chance that I saw opened ports when Avast! is turned on.

• Rsync to take the newest file. And a cron job?

  - by user1704877

  I have a log file on two different servers. The servers are under a load balancer so half the traffic goes to one server, and half the traffic goes to the other server. I need to take the newest log file from one machine and transfer that log file to the other machine. So if one log file is changed on one server, it gets updated on the other server. I think I need to use rsync. And do I also need to put it in a cron job?

• mount samba share on a vmware instance

  - by Riduidel

  I've a windows machine in which a linux server is run by a "VMWare player". From the windows machine, I want some folders to be mounted on the Linux virtual server. All this is done in a maven build (which is quite irrevelant here, in fact). From what I understand, to make these windows folders available as mountable ones, I have to do the following operations Share the folders as Samba ones using net share, this I have done. Access my virtual server and check which folders are already mounted (which seems to be doable using a less /etc/fstab), this I'll do soon Mount my samba shares using smbmount All that seems to my by far too hackish code. Could the same be done using ... say ... JMX/SNMP or any other high-level technology ?

• Windows 8 Remote Desktop only allows one user at a time?

  - by segmentation fault

  I tried connecting to Windows 8 using its built-in Remote Desktop feature, but for some inexplicable reason, it requires that no users are logged in on the target machine before a remote user can log in. This has never been a problem with rdesktop on Unixen; I could rdesktop from as many machines as I wanted and any logged-in users would never notice a thing. What's the problem with Windows? Any way to allow concurrent local and remote logins to a Windows 8 machine without hacks or cracks? The "guides" on how to do this that show up in the Google results all suggest replacing a system DLL with a hacked one, but that's not acceptable.
