• Disconnected from WiFi, Windows claims otherwise [closed]

  - by Manu

  I'm connected via wifi to my ISP's router/modem. While Windows says that I'm always connected, I keep getting messages from Netgear Genie that I've lost contact to the Internet, and I cannot access webpages until it comes back. There are two other computers in the house, one connected to the router via ethernet, the other via wifi, both seem to have no such problems. I've wondered if Netgear genie itself was the problem, but I am regularly disconnected even if I uninstall it. And I'd rather have it since it accurently tells me if I'm connected or not. Why does windows says I'm online if I can't access any online game, or website ? I've removed the connection, recreated it, I've even copied the settings to a usb key from the computer that has wifi access. Is there a tool that can tell me which program, if any, is disconecting me ?

• Looking for something like Google's Picasa [closed]

  - by Skizz

  I almost like Picasa, but there are two issues that irk me and I wondered if anyone knew of an application that does what Picasa does but without the following problems: Network drives. Picasa is hopeless with network drives. Ideally, I'd like photos to be stored remotely and thumbnail databases to be stored locally with a client-server set-up to update client databases. The main aim is to get updates propagated to clients efficently, reduce network bandwidth and have quick browsing on the client. It needs to be snappy when used over a wireless network. This is just a minor point but the folder view looks awful, especially when it uses those tiny thumbnails. (Also, what is it with folders being drawn vertically. Having spent years looking at folders orientated horizontally, turning them on their side looks so wrong.)

• MS Paint: how to enter proper text?

  - by Peter Mortensen

  How do I enter normal text in Microsoft Paint? Normally I don't have any problems adding text to an image in Paint. But I ran into this problem: The text is supposed to be "abcdefd" (entered in a text editor and pasted). The same characters appear if typed directly. So apparently it is using some other character set. How do I restore normal operation? Platform: MS Paint 5.2, Windows XP Professional x64 SP2, 8 GB RAM.

• postfix relay access denied from some IPs

  - by Caballero

  This is driving me nuts. I have Postfix/Dovecot set up on Centos 6 VPS for my emails. I can send and receive emails without any problems on my outlook (home broadband), on my Android phone (3G connection), however when I set up exactly the same email account on Outlook at my friends house I'm getting bouncebacks when I'm trying to send email (receiving works fine): 554 5.7.1 : Relay access denied Now if it wasn't working at all I'd understand, but why is it working on several internet connections, but not everywhere? Can someone shed some light on this? Where should I look for the problem?

• Maintaining Two Separate Software Versions From the Same Codebase in Version Control

  - by Joseph

  Let's say that I am writing two different versions of the same software/program/app/script and storing them under version control. The first version is a free "Basic" version, while the second is a paid "Premium" version that takes the codebase of the free version and expands upon it with a few extra value-added features. Any new patches, fixes, or features need to find their way into both versions. I am currently considering using master and develop branches for the main codebase (free version) along side master-premium and develop-premium branches for the paid version. When a change is made to the free version and merged to the master branch (after thorough testing on develop of course), it gets copied over to the develop-premium branch via the cherry-pick command for more testing and then merged into master-premium. Is this the best workflow to handle this situation? Are there any potential problems, caveats, or pitfalls to be aware of? Is there a better branching strategy than what I have already come up with? Your feedback is highly appreciated! P.S. This is for a PHP script stored in Git, but the answers should apply to any language or VCS.

• Connect ADSL modem SMC7904WBRA-N to CISCO RV082

  - by Cy.

  I have a SMC7904WBRA-N ADSL modem/router that connects to the internet with a static IP given by the provider. I've received a RV082 to create a VPN connection which is having problems to connect to the remote VPN Server. After many tries we deduced that the SMC7904WBRA-N is being problematic with the NAT and I have been suggested to put the SMC router into the appropriate DSL bridging mode so the RV082 gets direct access to internet with the static IP. Can you give me any hints on how could this be done? Which mode is that?

• Using pscp and getting permission denied

  - by Espen

  I'm using pscp to transfer files to a virtual ubuntu server using this command: pscp test.php user@server:/var/www/test.php and I get the error permission denied. If I try to transfer to the folder /home/user/ I have no problems. I guess this has to do with that the user I'm using doesn't have access to the folder /var/www/. When I use SSH I have to use sudo to get access to the /var/www/ path - and I do. Is it possible to specify that pscp should "sudo" transfers to the server so I can get access to the /var/www/ path and actually be able to transfer files to this folder?

• Bluetooth Connectivity that an error

  - by eka anggraini

  I have a bluetooth USB, every time I enter the bluetooth, bluetooth is active only a few seconds, after which it can not be used again In 'devices and printer' there is still a bluetooth but if you want to save the settings it can not, there are error message or bluetooth is revoked. I am using windows 7, whereas if use Windows XP smoothly no problems. This not only happens on my computer alone, my friend who has a build-in bluetooth also experienced the same thing with the same OS. Is there a patch / fix / update for its Windows? I've been brain-tweaking drivers for all but still can not.

• How to browse to a webserver which is reachable through the SSH port only

  - by GetFree

  I have a server at work which is behind a firewall (the company's firewall) so it is reachable only thrugh port 22 (SSH). I'm able to connect to the server with putty without problems. Also, that server has Apache running and listening on port 80 as usual. But I cant connect to the website using my browser since port 80 (and everyone else) is blocked by the company's firewall. Is there a way I can make my browser to connect to Apache in that server so I can browse the site I'm working on? Thanks.

• How can I guess if a USB cable will power my devices?

  - by rsanchez

  I've had problems with one long (4 meter) USB Mini-B to USB Type-A cable not being able to boot a 2.5'' external hard disc due to not supplying enough current. On top of that, the cable used a Type-A to Mini-B adapter for the Mini-B part, which probably made things worse. Three different shorter cables I got around made the hard disk work without extra current, so it was definitively the cable's fault. However, if I plugged the hard disk to the power, and used the long cable just for data it worked. Here is some related information on powering through USB cables: http://www.girr.org/mac_stuff/usb_stuff.html I have not any long cables that don't have an intermediary Type-A to Mini-B adapter to try them out. My question is: is there a way to guess if a cable will provide enough power for charge/disk drive power? Is it related to the length of the cable, to the build quality of the cable, or the fact that uses intermediary adapters?

• Interface to collect successful remote backups status

  - by Aseques

  I would like to deploy into our infrastructure a web interface that could register when the copies are finished and if for some reason they haven't. The current issue is that we are doing on site backups for customers, for each backup a mail is sent ad the end of the backup, the problems is that sometimes the mail isn't sent for a variety of reasons: System doesn't have internet Backup system crashed before sending the mail etc.. What I'd like to do is to have a web interface that the backup software cant visit after doing the backup (either if it's a success or a fail), that acknowledges that the backup has finished, after some time, I'd like to receive a report of the machines that hadn't done the backup. Is there anything remotely similar to this that I could use/adapt to our environment? UPDATE: Just found out this (paessler.com) that seems to be a privative solution of what I intended.

• Black screen with thinkpad edge e525, AMD radeon HD before and after installation, plymouth?

  - by carolien

  I have a new thinkpad edge e525 (which should work) and wanted to try ubuntu (first linux experience). With the ubuntu desktop-cd I had a blackscreen before installation, I could fix that with nomodeset. After the installation, when rebooting I got the black screen again. First I see some ubuntu colour with a green busted stripe. I have the same problem with the live boot, also tried mint live, the stripe gets pink. I installed xubuntu 64bit from an alternate cd and I didnt have problems until de reboot after the installation. Same problem, just a black screen with the green stripe than blackscreen. I tried several things: adding nomodeset to the bootmenu, but than I get: No connection to plymouth and it is stuck at checking the battery status. I tried to replace quiet splash with text. Didnt work either. actually one time I saw a blue booting image before that. I managed to get a root command though via the recovery boot. I didnt dare to just remove the plymouth package. Can I just delete plymouth or do I have to deinstall it as described in several ways. (Problem is, right now the notebook doesnt have a internet connection. And I dont know how to manage it with a usb stick?) Or do I have to install the AMD catalyst driver manually? (Again, how can I do that with an usb stick) I also tried this: Ubuntu hits a black screen after boot. Is there any solution without internet? And if I need internet which is the right one? Please explain step by step what I have to write and so on! Thank you! also tried: set gfxpayload=text and: just remove splash and adding vesafb.nonsense=1 to the grub editor, because I couldnt find it anywhere

• Trick to enabling FTP upload from an app in Windows 8?

  - by Craig

  I have an older Win32 app that uses FTP to upload some data to a server from time to time. This app works great in Windows XP and has been working fine in Windows 7 and Vista. For some reason, when running under Windows 8 it has trouble uploading its data. It appears to connect and upload the data OK but it has times out when disconnecting. The data does not appear on the server. I have limited visibility into the app while it's running so sorry for the vague nature of the description. My question is: Is there some security setting in Windows 8 that would keep this app from using FTP? When I check the settings it looks to me like I have it set up to prompt me about any permissions problems it might have, and I'm not seeing any prompts. I've tried running this app in XP/SP3 compatibility mode with no luck. At this point I'm just looking for some clues as to where to look.

• Dual monitor setup can cause boot problem?

  - by kriszpontaz

  I have a two monitor setup, one 22" (1680x1050 res., 16:10) and another 19" (1280x1024 res. 5:4). I've installed ubuntu 11.10 beta2 x86, and the installation worked fine, the system boot was successful. I've upgraded ubuntu from the main server, and after restart, booting with the kernel 3.0.0-13, my system hangs up with a purple screen, and than nothing happens (the system boots successful with the kernel image 3.0.0-8). Nvidia current drivers not installed, but if i install it, the situation is the same. I have an Nvidia 9600GT installed. I tried to boot with one screen attached, I've tried each port, but no luck at all. With kernel image 3.0.0-8 the system successfully boots with each display attached, but the farther kernels (3.0.0-11; 3.0.0-12; ect.) all freezes, even one display, or multiple attached. I have two systems with ubuntu installed, and the other (with Ati HD 2400XT, latest closed drivers) don't have any issues like this, I wrote about. Update: The problem solved by reinstalling the operatin system, without automatically installing updates during install, with only one monitor attached. After completing installation, and clean reboot, i've installed closed nVidia drivers. After all, i found it's safe to connect another monitor to the system, it's not causing any problems. Probably the situation stays like this.

• Monitor turns off about 1 second after turning it on

  - by r0ca

  Hi all! I have a hardware issue with some of the LCD monitors we have in our office. My problems is not related to video cards or anything else with the computer itself. I have 2 Dell 17" LCD screens that goes off (blank) after 1 or 2 seconds. The light remains green so it's not idling or sleeping. Just this morning, I had to replace one that goes off on 2 workstations and also on my laptop. Nothing to do with it. I tried the VGA and DVI connection w/out luck. I strongly think that this is something with a capacitor or something inside the screen but I can't figure out what it is... Is anybody heard of that kind of issue before? Regards, David.

• Windows XP not able to boot after loading isapnp.sys driver

  - by pragadheesh

  Hi When i power on my DELL Latitude E6400 laptop running on Windows XP SP3, i get a black screen and hangs after that. So I tried to boot through safe mode which hangs after loading the driver isapnp.sys. Doing a bit of googling i found out Windows XP not booting up including safe mode So I loaded my XP boot cd and tried Recovery Console. In the Recovery console, doing "dir" gives the error "an error occurred during directory enumeration". Then i tried chkdsk /p /r which gave "the volume appears to contain one or more unrecoverable problems" How can i fix these please. Thanks in advance.

• How to proceed when a bug in open source libraries is suspected?

  - by Suma

  We are using some open source libraries in our projects. Sometimes there are some issues found in some of them (most likely library bugs, but it may also be a wrong usage from our side, especially when sometimes documentation is not exactly 100 % complete). As the libraries are often quite complex, debugging them to pinpoint the source of the problem is sometimes quite hard. Can you help me to summarize what other options are there and how to exactly proceed with them? I have just recently hit some strange problems when using TCMalloc (Google scalable memory allocator) on Windows, so I would most welcome answers which would apply to this particular library, but more general answers are good as well. 1) Ask the maintainer/owner of the project for assistance. How can this be done? 2) Hire someone to identify and fix the issue. How to do this? How can I find someone with enough expertise in some particular library? ... any other options?

• Stress test a server for simultaneous connection

  - by weston smith

  I am trying to figure out a practical way to stress test a server for 300 to 600 simultaneous connections. Any advice? Thank you everyone for the help. To be more specific (sorry I wasn't before) this is a Flash Media Server on AWS that will be streaming live video. I've been having problems with the video freezing/buffering for everyone and I need to verify if its on the user end, upload end, or server end. I mainly need help with stress testing the server with 300-600 multiple request before going live.

• Upgrading Mac OS X 10.5.8 Corrupted Lightroom 2.7

  - by Tedd

  I use Photoshop CS4 and Lightroom 2. I recntly upgraded to 10.5.8 and began to have issues with LR. So, I reinstalled and downgraded my OS. I'm now running 10.5.2 on my MacBook 2.4G Core Duo with 4G RAM. Everything works fine now, but the downgrade also resulted in having only Safari 3.0.4 and and older version of iTunes. I can't upgrade either of those until I upgrade the OS but I'm reluctant to do so because I might have problems again. Any suggestions? Install 10.6 instead? What kind of issues can I expect from that?

• Cant register this user

  - by holgero

  I wanted to ask this question on meta, but it said, I have to log in first (which is where I have the problem!) I answered a question with this user. But when I tried to register and click on the stack exchange icon, it only displays three dots (animated) and never comes back. I suspected a firefox problem so I tried firefox on windows: And yes, I was able to create an account linked with my other accounts ( http://unix.stackexchange.com/users/27867/holgero and http://stackoverflow.com/users/1779245/holgero ) when I ran the latest firefox version under windows 7 in a virtual box. Then I upgraded my linux firefox to the newest version and deleted the other account under windows again. But still I cannot register this account ( http://superuser.com/users/177338/holgero ). On unix.stackexchange or stackoverflow I never had any problems with the registration, superuser seems to be different. So, how do I register this user and have it linked with my other stackexchange accounts?

• Windows 7 wake from sleep and UTC?

  - by Joshua Elliott

  I've been having problems with windows 7 waking from sleep after one minute or so on my laptop. I also have ArchLinux installed on this computer. A while back I tried a registry tweak to get windows to use UTC so it would play nice with Linux. The registry tweak didn't seem to work and my windows clock was always wrong. Today I deleted the registry entry that I added, and the problem with sleeping seemed to go away. Can anyone make sense of this? The registry entry I added was: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation] "RealTimeIsUniversal"=dword:00000001

• How to monitor the size of files in Windows folder?

  - by zladuric

  What are some of good ways to automatically monitor the size of files in a directory and send warning email if they get close to a certain limit on a Windows server? I have a Progress DB installation to keep in check, and last week we hit some problems. Apparently, the size of extents has hit 2GB - and Progress won't work past that - we needed to open a new extent. I'm coming from a Linux environment, so I don't know what are the usual to monitor this in a Windows environment (or monitoring tools whatsoever). I prefer some generic solution, as I have a mixed environment (Windows 2000, Windows Server 2003, Windows Server 2008 R2). Thanks in advance for all usable alternative answers.

• Logon script does not run for all users

  - by Herohtar

  We have a standalone common-use workstation running Windows XP Pro SP3 and have created a script using Javascript (scriptname.js) that is to be run for each user. The file was added as a user logon script via gpedit.msc and tested using a newly created user account as well as an existing user account. The script ran and functioned as intended on both accounts; however, a few existing users have informed us that the script is not running on their accounts. All user accounts are members of the same groups and have identical permissions. We already have an existing script (but in this case, a batch file) that is applied in the same manner and it runs for all accounts without any problems. Furthermore, on the accounts where the new script does not run during logon, it can still be run manually and works fine. So the question is: what would cause this script to not run during logon on certain accounts? Thanks!

• Understanding RewriteCond in .htacces files

  - by Paulo Bu

  I'm having problems understanding how RewriteCond directive works. So far, it's pretty clear that it compares to strings to apply a RewriteRule. I have this file: <IfModule rewrite_module> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ app_dev.php </IfModule> This works for me but I don't know why it works. So far in the RewriteCond directive I understand: if the value of REQUEST_FILENAME is NOT a file in the hard drive then allow the rule This doesn't have sense becouse app_dev.php after substituting is a file in the hard drive. Anyways, could someone enlighten me with this issue? I am having a very harsh time figuring out how this works.

• Alternatives to amavis for RAM-bound server

  - by rsuarez

  I'm running a small VPS server that works as web and mail server. It has only 256MB of RAM, and it's sucking 100MB of swap constantly. I've found that one of the culprits is amavis, taking about 30MB of resident memory, and would like to ditch it and use some alternative. I don't have much mail daily, so it being a bit slower wouldn't be a problem. I'd like to avoid Spamassassin altogether, if possible, because it's quite big even if used in offline mode. I'm already using RBLs and a few small blacklists, and used greylisting for a while but abandoned it because it gave me a few problems (don't remember which; I think it was related to not configuring properly white lists for several big ISPs). So, is there some alternative to amavis that I could use without much RAM (and if possible, CPU) usage? Thanks in advance.
