• Looking for internet traffic manager software for Windows 7

  - by Semyon Perepelitsa

  I have 128 KB/s (1 Mbit/s) internet connection. Not quite fast for downloading big files, but it is okay for internet browsing. When I start big file dowload, I cannot surf the web normally: pages appears slowly, especially pictures there. Therefore I pause downloading, but I'm regularly spending much time on reading articles or leaving the computer alone, when I can allow the file being dowloaded. Is there any software that can automize the process of pausing and resuming download or simply automatically regulate internet speed for each application using Internet? I download files using different software and protocols (Download Master for http, ftp; uTorrent for torrents; many other programs for updating themselves), so I don't want to be tied to particular program for downloading.

• Linux Mint on VirtualBox has no internet connection

  - by Martin

  Physical machine: Mac Mini running OSX 10.7.5 Virtual machine: Linux Mint 15 Cinnamon 64-bit Using VirtualBox. I am trying to make the linux connect to the internet. For some reason I can access the host computer with 192.168.2.100. Its set up to show me a web-page that says "It works". This I can see from the linux. But I cannot reach anything on the internet. Either FireFox says "Unable to connect" or when I run nslookup google.com I get connection timed out; no servers could be reached. My setting on VirtualBox under the Network tab are: Bridge Adapter vnic0 promiscouos Mode:Allow All`. If it makes a difference, the host has a WiFi connection to the home router. What have I missed?

I want to know if somehow i can use teamviewer to get a ip/hostname that is accessible from the internet and host a webserver.

• First request too slow even if I have a load balancer in the back

  - by adrian7

  I have an Apache 2 on Centos + bind with a wordpress website on it (e.g example.com). I have also set up, on another server in a different contry a load balancer (varnish:80 + nginx 127.0.0.1:8080) for it - which task is to server all static content under /wp-content/. Using Simple DNS editor I added an A entry to cdn.example.com pointing to the server's IP. So no extra work from a 2nd dns server. Then using htaccess I redirect all requests to jpg|gif|css|js files to cdn.example.com. That works and all files are saved on the "cdn" server and served right away. My problem is that for the first time I enter on example.com (e.g after restarting the computer or closing the browser) the load time is 1 up to 3 seconds, while any subsequent page loads take only 300 to 600 miliseconds. I know it might be a DNS issue, but I have done a cache check on several websites and cdn.example.com indicates the right IP. Do you have any ideas where I should dig to solve this first-time slowness?

• does any sync software find files that have moved paths within a folder?

  - by kpierce8

  Say I have a pictures folder which I reorganized on one computer. I'd like to use that directory as the base and compare it with another version on a backup drive. Will any sync/compare program find that a file in one folder has moved locations within a compare folder. For instance say I reorganized my pictures from trips into folders by year with the trips folders inside each year folder. If I use a regular compare utility I wind up with two copies of everything that's moved in different locations.

• Show Slave Status not working from console, nor client.

  - by Mr. Leinad

  Hello, I have a somewhat strange case. Whenever one of my coworkers executes this line: show slave status; from their MySQL clients, it works smoothly. But if I do that, it says: ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation We are all going against the same database, and if I check privileges I can see: GRANT ALL PRIVILEGES ON . TO 'usermysql'@'%' IDENTIFIED BY PASSWORD 'password' There's something wrong with my computer.. but I can't pinpoint where it is.. Thanks EDIT: It's kinda bizarre.. it goes through a VPN remotely. But if I change the internet connection, then it works.. If the previous internet connection is restored, it doesn't.. Could we classify this among the great mysteries of the world? Or someone has an idea?

• Firefox (on windows) constantly consuming 10% CPU - is there an add-in to find the rogue tab?

  - by tbone

  I often have many Firefox windows open, each with many tabs. Now and then one of the tabs will be running a web page that for some reason consumes lots of resources. Right now, I have a tab somewhere that is constantly consuming 10% of the CPU...which would be fine as my computer can easily handle that (see specs below...all other apps are responsive), but it seems to slow Firefox down....everything, everywhere is extremely laggy in Firefox, I can see pauses while I type this. Is there: - a way I can isolate separate instances (or even tabs) in FF into a separate process, so one rogue tab doesn't bog down FF across the entire system? - maybe an add-in that can either identify tabs consuming lots of CPU, or maybe a way to "shut down" activity on tabs you haven't used in a while? Firefox 3.6.10 Windows 7 Ultimate 64 i7 920 @ 3.6 GHz 12 GB Ram

• Outlook 2007 attachments wont preview

  - by Slace

  When I get an email with an attachment in Outlook 2007 that I should be able to preview (ie - image, word doc, etc) I get the following error: This file cannot be previewed because of an error in the following previewer: Microsoft Outlook image previewer To open this file in its own program double-click it. (obviously the previewer changes name depending on the type) The computer is a clean install (it's only 5 days old) and I remember I was at one point able to preview within Outlook. I'd really like this feature to be back working, I've tried the usual exit Outlook, restart Windows, etc but to no avail.

• How can one-handed work in Ubuntu be eased?

  - by N.N.

  My right hand is temporarily immobilized and I would like to do some minor general work on my computer. Mostly web browsing, mailing and file and directory browsing and editing. For this I currently use Firefox, Thunderbird, Nautilus and the GNOME terminal (I have already asked a specific question about Emacs). Are there ways to ease such, or any other general, one-handed work in Ubuntu? I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not exactly what I am asking for. I want to ease whatever little time spent one-handed in Ubuntu and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I do realize I should avoid unnecessary strain. The main thing that is much slower one-handed is writing. Since I am only temporarily immobilized it seems to make no sense learn a new keyboard layout. I would be surprised if I managed to learn and become more effective with a new keyboard layout (than one-handed QWERTY) before I can use my other hand again. What I have already found: Sticky keys for making it easier to enter keyboard commands. When writing one-handed there are more cases of where it is useful to paste in phrases rather than to reenter them. It is easier to use Super+S rather than CtrlAlt+arrow keys to switch work space.

• Game crash/Screen freeze recovery (without shell or reboot)

  - by Asavar Tzeth

  I am an old Windows PC gamer, now converted into Ubuntu (Linux) lover. I am even going so far as to attempt to replace all my games in a Windows dual-boot with Wine and it is going well. However... Even if Linux is less prone to crashing, games, especially the windows ones (but also a few native) can crash. My problem is when this is in full screen and the computer becomes non-responsive. In Windows you can solve this with ctrl+alt+delete, but Ubuntu lacks this feature and my only choice is a reboot. Is there any Ubuntu version of this feature? Of course excepting the ctrl+alt+F1, find and kill process method. It is fine if you know how to do it, but too slow and difficult for the typical gamer. I believe strongly in Ubuntu as the future gaming platform in one form or another. If this feature does not exist, then the Ubuntu team should address this as fast as possible, since it is critical for all old Windows gamers. Thank you for your time. Asavar Tzeth (Alias)

• I'd like to archive files from Ubuntu to Windows between two computers on a shared home network

  - by Wabbitseason

  I have an old laptop running Ubuntu 9.10 which I use as a LAMP environment for web development, and I have a comfortable, powerful desktop computer with Windows 7 installed on it. These two are connected to a home router so both can access the internet. I have been able to set up Samba so I can mount my Apache home directory so it is accessible from Windows and is mapped as a network drive. What I'd like to do is access some Windows folders from Linux so I could automatically create backups (with cron scripts) of my work to physically different locations on the Windows box. Perhaps at a later time I'd set up a local Subversion repository but I'd love to keep backups of that on the Windows drives too. Using Ubuntu's Places/Network menu I can see my desktop but I'm unable to log in to that despite having created the corrent username and password on Windows. All I can get is the following error message: "Unable to mount location. Failed to retrieve share list from server." What could be misconfigurated?

• Windows XP Activation failed, now what?

  - by user26379

  I have a computer with (presumably unlicensed) Windows XP. The activation (over the internet) failed, and I now I cannot get into Windows. After calling Microsoft, it seems like I will have to reinstall everything and install a freshly bought operating system. What are my options here? Is it worth trying the millions of keys and key generators out there? EDIT: I have no way of contacting the manufacturer (it's a no-name box, definitely not Dell, HP or IBM). Would there actually be a key supplied with my version of XP? If its not genuine, wouldnt I just have any old key? And that key would fail activation any way?

• No write access on Windows 2008 workgroup share

  - by Serge - appTranslator

  Hi All, I'm trying to access network shares on my new Windows 2008 server (workgroup) using my server's local admin account. I can read files but not modify them. Permissions (sharing + file system) say: Users = Read only. Admins = Full Control. Even though I connect using my admin account (net use x: \\server\share /user:server\me), I can't write. OTOH, I have another share on the same computer where users have Read AND Write. I can write into that one. What's the problem? Does it have to do with UAC? TIA for your help.

• Is it possible to replace the Logitech G500 wire without rebuying the mouse?

  - by leladax

  It has to be replaced ideally in whole, from the point it starts inside the mouse (with a white 4-5 piece of wires connection) to the end (of the USB connector to the computer) or at least to a considerable length because there is fatigue very near the mouse and the more I fix it there with soldering the closer it gets to being unfixable or reaching towards 'inside' the mouse where fixing it will be hard or impossible. So I wonder if there is a way to get a replacement of the whole thing or at least the inside-the-mouse connector to a certain length. Also I wonder if other mice types are identical in the connector of the inside.

• A software to lock regions of a screen to prevent any windows from overlapping

  - by cybervaldez

  I've just installed nexus dock (a similar application like rocketdock), after playing with the preferences i've come across a very curious option (under position & behavior) that says: Prevent maximized windows from overlapping the dock. With it enabled, any application I maximize(and i do mean any) won't overlap the dock, it's really great. So i'm thinking perhaps there's a software that does this kind of feature which is really ideal for keeping my workspace really organized. I really hate repositioning and resizing my windows everytime. Of course there's always the manual way of doing these but it's just too much of a bother when someone from the family uses the computer. Do you know any software that does this? even a software that can just save/remember window positions would also be nice too.

• How to configure something like "Reflexive ACL" on OpenBSD?

  - by Earlz

  My U-Verse modem has something called "Reflexive ACL" described as Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). This seems like a pretty good way to keep from having to maintain a firewall on each computer behind my router that gets handed an IPv6 address. It sounds about like a NAT, which for my small home network is all I want right now. Now my modem sucks as a router though, so I'm in the process of configuring an OpenBSD router to do that. I've got IPv6 supported and all that and my OpenBSD router will hand out IPv6 addresses by rtadvd. Now I want to keep people from having instant access to my local network through IPv6. How would I best do something like Reflexive ACL with pf in OpenBSD 5.0?

• Reverse SCP over SSH connection

  - by pavpanchekha

  I pretty often need some file from some server when I'm on my laptop. But if I don't know where that file is, I have to ssh into the server, look around, exit, and then scp server:file .. If I'm working with my desktop and my server, both of which have static IPs, I can just SCP the file in reverse (scp desktop:~ file), but I can't do that for my laptop. Is there any nice way to SCP a file backwards over an SSH connection? So that the computer I connect to with SSH sends a file backwards to the client?

• After upgrade to Windows 8.1, no Skydrive icon in task bar

  - by Jeremy Butler

  I upgraded to 8.1 and now I don't see the SkyDrive icon in the task bar, nor the green light under it indicating the my computer is communicating with SkyDrive. When I go into Control Panel |..|Notification Area Icons, SkyDrive is listed and noted as Up to date. However even though I mark it to Show Icons and Notifications I don't see any icon in the taskbar. Is it supposed to be this way, or do I have a problem? I kind of got used to that little green synchronizing indicator giving me a warm and fuzzy feeling.

• sharing life experience

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter). I have send that question to stackoverflow before when I am at first year.

• Ubuntu 10 installer stops after asking for username and password

  - by Jorn

  I am trying to install Ubuntu 10.10. It's running fine, until I get to the step where it asks me to specify my name, computer name, user name and password. I have filled in all those fields and all of them display a green checkmark. However, the Forward button doesn't enable. The installer continues copying files, and when it's done it says Ready when you are... in the status bar. Still, Forward is disabled. Anyone know what the problem could be?
