• Monitoring/logging a malfunctioning internet connection

  - by Pekka

  I have a mysterious internet connection problem: Every 15-20 minutes, the connection will become very slow, and take 2-3 minutes for anything to load. I've had a technician from the ISP over here to test the hardware, and everything is in pristine condition. They have no other explanation than a configuration error on my machine, a possibility I can exclude 90% because I'm experiencing the same problems with another machine. I will have to monitor the situation now, and I would like to run a program that logs when internet connections become slow. I thought about putting something together using at and wget. Does anybody know of some other tool for this that does this out of the box - maybe something with an adjustable request frequency, logging connection speeds etc.?

• Is it normal for the laptop charger to spark when plugging in?

  - by Cd-MaN

  All the laptop chargers I had until now sparked whever I plugged them in. This is true for my old charger (the bulkier / rounder Dell model) and the new charger (the flat Dell model) with two different Dell laptops, however until recently I didn't give it much thought. Then, in the last couple of months: I shorted out a conference room and melted the floor a little (the wire caught fire) The second charger (also a Dell original) died, taking the power strip with it I'm wondering: Is it normal for laptop chargers to spark when plugged in? Specifically new, original Dell chargers Is there a "correct" way to plug / unplug chargers? Do I need to first unplug it from the wall and then from the laptop / do I need to first plug it into the wall and then into the laptop? May the problem be caused by the fact that I leave sometimes the charger plugged into the wall without connecting the laptop for longer periods of time (up to a day)? PS. I'm talking about Europe, so 220V and this happens in many places (at home, at my parents, at work, in hotels I trave to, etc)

• Opera 11 - prevent panels/tabs opening when examining RSS feeds

  - by Damien_The_Unbeliever

  I've reviewed the suggested questions, based on my title, so apologies if I'm going over old ground. Opera 11 recently came out. Whilst I use it as my RSS aggregator, I don't use it for any other messaging purposes. So I'm annoyed with, whenever I open Feeds-Read Feeds, I suddenly get the panels side menu, and the Mail panel opened automatically. This is new behaviour from the 10.x series, and I can't seem to find an option to turn it off. When I go to "Read Feeds", I just want the feeds window to open. That's it. Any ideas?

• Windows Command queue?

  - by Stefano

  i'm thinking if does exist some kind of software that can put in a queue a bunch of windows commands... for example i can say to first copy some file somewhere, then rename those, then delete the old files, then edit one of them etc.... without waiting the effective execution of any of those passages.... this could be useful when copying big files that take a lot and i don't want to sit in front of the computer keeping the eyes on the progress bar... does exist anything like this?

• RAID 1 in ubuntu 12.04

  - by Bavly Hanna

  Right now I have a small file server to which I have loaded ubuntu 12.04 desktop on a small 160gb harddrive. This harddrive is the primary drive from which the OS boots. I want to move all my data to my file server so it can be shared on the network (contain in 2x2TB harddrives in my desktop. The 2TB drivers are in raid 1 (hardware). I simply want to move them to the file server and set it up so that they are in software raid 1. If at all possible I'd like to be able to do this without losing any info on the drives. I've searched around and the guides i find describe raiding drives for boot driver, but these wouldn't be boot drives just regular storage drives. If someone could tell me how to perform this or point me in the right direction it would be much appreciated.

• PHP/Oracle Connectivity randomly "drops out"

  - by user20555

  Hi! Here's the current situation - I have two web servers (for now named A and B) and two database servers (named C and D). The web servers are quite old, and are running an early version of Apache 2 + PHP4, while the DB servers are running Oracle 9i and 10g respectively. We're experiencing a strange problem connecting (via PHP code) to database A while on web server B only. Web server A has no issues at all... Randomly, web server B will report a "Not connected to Oracle" error (3114). I can't see a real pattern with this, but refreshing a few times seems to fix the issue. Apparently there are no drop-outs on the network interface, which leads me to believe that there's some misconfiguration between PHP/Apache and Oracle (which uses connection pooling). We're running SunOS 5.8... Any ideas?

• Router Suggestions [closed]

  - by zamN

  Lately I've been having router problems with my Linksys WRT54G when it comes to signal strength. Anyways I am thinking of getting a new router since the linksys is about 5 years old now. I'm just curious what router to get because I want to get the most out of my money. I already have a modem that I will connect to the router. I don't need voIP or any of that. All I simply want is just something that is going to last and will not have any stupid problems.

• How can I check that I'm not frying the chipset on my 945 gclf?

  - by Journeyman Geek

  I'm running an old 945 gclf as a home server. Its an odd little system which has a passively cooled single core atom 230 processor, and a small heatsink/fan combo over the chipset. lm-sensors/sensors detects one temperature sensor which I guess is the processor. coretemp-isa-0000 Adapter: ISA adapter Core 0: +38.0°C (crit = +100.0°C) The fan on it is making rather horrible noises and I am considering unplugging it or using a speed reducer. There's also a risk it may fail anyway. Is there any way I can monitor the temperatures of the chipset or be warned of any issues with it? Is there anything specific I can watch out for that would indicate trouble?

• How to prevent boot manager missing after cloning a win764 image using Ghost 2003?

  - by hirogen

  I am running ghost 2003 command -fdsp, but once we have cloned the image and restored it onto exactly the same make and model machine, we are force to run win7 setup and run a repair which fixes the boot menu, I want to prevent this requirement to fix the problem, any suggestions besides the obvious of using Windows AIK tools, new versions of ghost/clonzilla. I want to prevent the problem in the first place, it's 1 partition only, on a levano workstation m82 with UEFI and a 100mb system reserved partition. Windows Boot Manager screen and states: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.Insert your Windows installation disc and restart your computer. 2.Choose your language settings, and then click "Next." 3.Click "Repair you computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. Status: 0xc000000e

• Windows shows incorrect free space on Raid 10 volume

  - by Adenverd

  I have 4 1TB hard drives in RAID 1+0 configuration. Theoretically, I should have ~2TB of available space. Windows says the drive has a total size of 1.81 TB, which I'm fine with. As far as files on the volume go, I used WinDirStat to determine that I have 552.8GB of files on the volume. This means that I should have somewhere around 1.3TB minimum of free space. Yet Windows shows the drive as only having 492GB of free space. Are there hidden files somewhere that I can't see (I have show hidden files/folders turned on)? Does Windows not recognize that old files have been deleted? Is there any way to correct this problem?

• Missing Driver - Video Controller (VGA Compatible)

  - by arahant

  I have a HP 2000-2106TU Notebook PC running Windows XP. I want to get the brightness keys to work. They are placed over the F2 and F3 buttons and are meant to be used in conjunction with the Fn key. But these combinations do not work, though other Fn keys such as the volume control keys do. I see a missing driver for a device called Video Controller (VGA Compatible) in the Windows Device Manager. The hardware id is PCI VEN 8086 DEV 0106 SUBSYS_1858103C which a Google search suggests is in an Intel HD Graphics family, but I don't know where to locate the driver. HP's driver scan does not help, as it does not show any missing driver related to video/graphics. What can I do next?

• Cleaning cruft from the stored configs database

  - by Zoredache

  I have setup stored configuration primarily as a method to manage my ssh known_hosts. Unfortunately as I retire hosts the old configs still exist in my database. The answer seems to be run the command puppet node clean <hostname>. The problem is that while this does command does run, and does clean up some data, it doesn't seem to clean up everything. For example I can still find values in the puppet_tags table that only applied to a hosts that no longer exists. What should I be doing to keep my stored configuration database clean of all extra junk that seems to be building up? P.S. Can anyone point me any documentation for the stored configuration schema?  If I could find good documentation, or at least an entity-relationship-diagram, I would be tempted to just do some manual clean-up.

• Best Practice for upgrading PHP On Production Systems

  - by Demic

  We Have two load balanced web servers running php 5.3. I've been asked by our dev team to upgrade php to 5.4 because they need certain functionality it will bring. The main issue is that 5.3 is the latest thats been built into the distros repository, so to upgrade using the package manager, Ill need to add another 3rd party repo. I dont have a problem with this per se, but Im concerned about using a package from a "non official" source. The other option is to compile php from source, but I guess this will prevent me from using the package manager to upgrade at any stage in the future? So I guess Im just looking for some guidance on which way to go. Compile from source or install from any old repo that purports to supply php 5.4? Or perhaps theres a third option I havent considered? Thanks in advance Demic

• How to delete a file after vlc finishes playing it?

  - by Codezilla

  I know you can have vlc shut down your pc after you finish playing something but I'm trying to figure out a way to delete the file, preferably with a confirmation dialog box after you finish playing something. Ideally it would only do this if the file was actually played to at least 90% of the file so as not to have unnecessary deletions but that may not be possible. Running a batch file to play the video would work, but it'd have to be something easy to do. Having to edit a batch file with the name of the video to play each time would get old fast. Any ideas?

• SSH + SAMBA + LDAP question

  - by Mejmo

  Hi, I have SSH + LDAP working (I can log to Server2 with credentials from LDAP server Server1). Now, I would like to add Samba server (Server3) and it would be nice if it authenticates the users like Server2. How can I achieve this ? As I see Samba schema and the schema used for storing Unix users are different. So if I change password in Samba schema, I would be able to log in with the old password. I need centralized storage of username/passwords. If I change it once in phpldapadmin, it means for samba and ssh. Thanks.

• Where the does sender's name in an e-mail come from and how can I change what name I send?

  - by ChimneyImp

  At work, we use Google Apps to host our e-mail and Outlook to access it. I have a user who recently changed their name. I changed their e-mail address and their account name, but when they send e-mail their old name still appears, no matter whether they send it using Outlook or the gmail web client. For example, e-mail from them in the Gmail web client reads Oldname [email protected] instead of Newname [email protected]. I'm trying to make the user's new name show up when they send an e-mail. Where is the sender's name stored? Is it a part of the e-mail specification, stored in some header somewhere, or is it stored in the e-mail client? If it's possible, how do you change the sender's name in Gmail?

• What security changes are necessary when connecting DSL modem directly to PC instead of router?

  - by Mike B

  Windows XP I have a user with a single PC that was connected to the internet via a standard home router. The router is now having hardware-related issues and to save money, they're considering connecting the PC directly to the DSL modem since they don't need to share the internet connection or need wireless functionality. If they decide to do that, I'm concerned that this will introduce additional security concerns. Is the Windows Firewall sufficient and Microsoft Security Essentials sufficient for protecting a computer directly connected to a DSL Modem? Or is other security software needed here? Ideally, I'd like to avoid having third-party firewall software constantly bringing up alerts and asking them to approve everything. Also, just to clarify, their use cases are just internet browsing and email.

• Emacs doesn't use ~/.ssh/config when accessing files on a remote machine

  - by Yotam

  I have a fresh install of arch Linux. I've installed Emacs from the rpos, and my home directory is mounted from a separate partition. I have old settings I've used on my ~/.ssh/config along with authentication keys I've regularly used before. Now, when I try to connect to a remote machine using Emacs, Emacs asks for my password and uses the wrong username. Clearly, Emacs doesn't access my config file. When I try to ssh or scp directly to the machine, things work fine. What do I need to update?

• How can I select multiple windows to tile in Window 7 (like you could in previous versions)?

  - by Daniel

  I've disabled Aero Snap, is there any way to restore the old method of window arrangement allowing you to do side by side, or top and bottom, etc.? All you had to do before is select the windows you want and right click. I know the menu is still there in Windows 7 but it is only for the whole Task Bar, and you can also do it from the Task Manager but that is more complex to get too. After looking all around I cannot find a way to restore any such right click menu for each application. Is there a way to tile like this for individual windows or groups?

• Can't connect to ssh after nfs problem

  - by MihaiM

  Hello, I had a problem yesterday with a server that lost connection (S1). From that server, there was a dir shared with NFS to another one (S2), no homedir and not in $PATH, but a dir to store old files for archiving. S1 was back online after a few hours, but now I cannot access S2 because of this (and I'm sure it's because of that because all other services are running without any problem). The ssh connection hangs here: debug1: Entering interactive session. I know a reboot will do the job, but considering this is the NAS of a big app, my bosses will kill me if I do it. Is there any other way to get over this? I tried with different users, but all of them hang in the same place. I connected with HP iLO and not even there I cannot use my username. Thanks in advance.

• Is it possible for a router to "go bad" with time?

  - by JQAn

  I've been having problems with my internet connection over the past weeks (intermittent disconnections, slow transfers, etc), and my provider keeps telling me that the problem is not on their end. I have cablemodem with a wifi router (this router was not provided by them). The router is quite old (DIR-300), so I'm starting to wonder if it could be the issue and if I should replace it. Is it possible that it is the cause? Can they become so outdated that they cause intermittent interruptions of service? If I reset the modem and the router, they work fine for a few hours, but the problems starts again after a while.

• Running a cronjob

  - by Ed01

  've been puzzling over cronjobs for the last few hours. I've read documentation and examples. I understand the basics and concepts, but haven't gotten anything to work. So I would appreciate some help with this total noob dilemma. The ultimate goal is to schedule the execution of a django function every day. Before I get that far, I want to know that I can schedule any old script to run, first once, then on a regular basis. So I want to: 1) Write a simple script (perhaps a bash script) that will allow me to determine that yes, it did indeed run successfully, or that it failed. 2) schedule this script to run at the top of the hour I tried writing a bash script that simple output some text to the terminal: #!/bin/bash echo "The script ran" Then I dropped this into a .txt file MAILTO = *****.******@gmail.com 05 * * * * /home/vadmin/development/test.sh But nothing happened. I'm sure I did many things wrong. Where do I start to fix all of this?

• Using LDAP/Active Directory with PIN based authentication

  - by nishantjr

  We'd like to integrate our service with LDAP, but because of hardware constraints, we're only allow 4 digit user ids and passwords. What would be the best practice for performing such an authetication? We've considered adding User ID and PIN attributes to the LDAP user schema, but we're not sure how happy people would be with modifying their schema to interact with our service. The PIN attribute would have to have the same support that native user passwords have. (hashing and salting etc.) UPDATE Another consideration is how ldap_bind works with this scenario. How do we get it to use an alternate authentication method? Can this even be done without affecting other services that use the same LDAP server?

• Delete protected files in ntfs?

  - by Balchev

  I want to delete an old Windows directory from my system drive (C), but I am unable to due NTFS permissions. I tried from Win 7 and Win 2003, but can't do it. I tried safe mode as well with same result. Is there any way to work around this (other then formating the drive)? Perhaps changing the owner or something? It errors at files like "oldwin/bfsvc.exe". Is there some "superuser" in windows similar to linux root account? Thanks

• What's the best way to install software in Ubuntu?

  - by the0ther

  I'm new to Ubuntu and have been away from Linux for a while. I'm used to Windows and find this tedious on Linux but I want to give it a shot. My tendency is to prefer GUI tools over command-line, and Ubuntu is a distro that seems to cater to usability. I note it is based somewhat on apt-get which I've heard good things about. What's the best practise for installing apps on Ubuntu? Should I prefer to try my options in this order? Synaptic Package Manger apt-get on the command line .tar.gz files (old school)
