• Problem with usb wireless mouse

  - by aiacet

  Recently I have started having problems with my wireless mouse (Wireless Optical Mouse MI-4910D). Sometimes when I start my PC or during a game the pointer/arrow stops moving. When the PC boots the pointer is locked in the center of the screen. If I'm lucky it helps to change the USB wireless adapter from port 1 to port 2 but sometimes this trick doesn't work and I have to restart my PC to get the mouse to work again. Like you can see in the product web page this mouse don't have a driver but only a tool to solve some problems. Thank you in advance to all the "super-users" that reading this question would be help me Ajax

• How can I obtain/build a wireless volume knob for Windows?

  - by Mr Grieves

  I use my computer as a media center and simply love it. It's an older box running XP and it works better than everything else I've tried turning into a media center (Windows 7, Vista, several Linux distros, etc). The only thing I hate is having to walk to my audio amp to turn the volume up or down. I can use the Windows volume slider or any keyboard with keys to control volume. What I'd really love is to have a wireless knob which I can put anywhere when listening to music (e.g. kitchen) which controls the volume. It seems so simple yet I can't find it anywhere. Having controls for pausing and moving to next song would also be terrific. Griffin's Powermate could do the trick but I'd really want it to be wireless. Do you know of something I can buy or build myself to serve this purpose?

• mailman not relaying email to external address

  - by gozzilli

  I have a setup of mailman with postfix on an ubuntu server 12.04. My problem is that mailing list emails are not forwarded to email addresses external to my institution. However the initial welcome email is received by everyone, internally and externally. in fact, a simple email from command line with mail is successfully sent to anyone after that, mailing list emails are only forwarded to internal addresses. the domain name I'm using for the server is not that of my institution who is hosting the server. Here is my main.cf: myorigin = sub.myinstitution.tld mynetworks = 127.0.0.0/8 xxx.xxx.xxx.xxx/16 # this is my institution ip range relayhost = smtp.myinstitution.tld inet_interfaces = loopback-only local_transport = error:local delivery is disabled virtual_alias_maps = hash:/etc/postfix/virtual smtpd_recipient_restrictions = permit_mynetworks myhostname = mywebsite.tld mydestination = $myhostname, localhost.$mydomain, localhost I also found these two links on serverfault and ubuntu forums, but neither of these solutions seem to do the trick for me. Any help would be much appreciated.

• Is my website running on an iPhone?

  - by Stefano Borini

  Provocative question, but in any case, this is what it would appear... unless there's some other reason, of course. In my cystat wordpress log, I obtained the following entry IP Browser OS Date Method Type URL 127.0.0.1 Safari 419.3 iPhone July 30, 2009 7:39 pm GET BLOG /blog/ The IP address is the IP of the visiting client. It's clear that this is not possible. Why do I get 127.0.0.1 as IP? cystat bug? some weird network trick I am not aware of? or is my website really running on an iPhone, and the guy at the applestore is reading my blog ?

• Quickly translate a word from English

  - by licorna

  I'm always reading English, but I'm a Spanish native speaker (I'm working on my thesis). Sometimes I need to translate a word into Spanish, and what I do now is to open a new tab and go to Google Translate and then put the word into the input field. Just a quick translation, one word or a small phrase. I'm a Mac and Firefox user. Is there a better way to achieve this? I was thinking that maybe a dashboard widget would do the trick and I was looking for one. The other option is to install the Google Toolbar, but I really hate toolbars. I don't know, a good Firefox extension maybe?

• CentOS 6.5 server time zone won't persist?

  - by Codemonkey

  I'm setting my timezone like so: ln -sf /usr/share/zoneinfo/Europe/London /etc/localtime It works fine, I check with date and all is good. But then a few days later I'll realise it's reset itself to CEST, so 9am becomes 10am, etc. The server is located in Paris, in the CEST time zone. But I should be able to use any zone I want, surely? I (and most of my users) am based in the UK, so I want to operate on that timezone. I just did a yum update and noticed it wanted to update tzdata. That had the effect of changing from BST to CEST, but I don't think it's the only thing that triggers the change, as I'm sure it's gone wrong on days where I've done no such update. I could be wrong though. What's the trick to set a timezone permanently? Thanks

• Unable to connect to remote MS SQL Server 2008 Express SP3 instance by name

  - by Max

  I am trying to connect to a remote MS SQL Server 2008 SP3 x86 Instance using it's name. At the first glance all seems to work well (e.g. it is possible to connect to the server locally and succesfully telnet it's port remotely), but there is a thing I can't understand... This line should connect us to the default instance of remote SQL Server: osql -S ServerIP -d MyDatabase /U sa -P MyPassword and it does the trick, however the next one: osql -S ServerIP\MyInstance -d MyDatabase /U sa -P MyPassword ends up with the following error: [SQL Native Client]SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. [SQL Native Client]Login timeout expired [SQL Native Client]An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. The only instance running on the server is MyInstance, which is (I guess) the default one. Could you please put some time in explaining the issue.

• how to master in Windows administration [closed]

  - by Mateusz

  what is, in your opinion, best way to become real Windows, advanced administrator? Of course it's possible to obtain MS Certificates, but they're rather very expensive. Almost two years of everyday working on Linux machine, teach me, that it's very important to read system logs. Anyway, I assume that it's enough - I think that you must be familiar with almost any hive in you registry and each trick in Windows CMD and VBS- although it's high time for PowerShell, still on many maschines, you have only an opprotunity of using CMD by default (and their owners are reluctant to install anything else). How I can accomplish this task? Which groups follows (superUser - it' obligatory), which articles read?

• How to troubleshoot if a zip file is valid or if it is big file size to be unzipped ?

  - by mireille raad

  Hello , I am trying to unzip a file with the size of 2GB I am getting the following error : unzip CLTE_C_08.zip Archive: CLTE_C_08.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of CLTE_C_08.zip or CLTE_C_08.zip.zip, and cannot find CLTE_C_08.zip.ZIP, period. After some googling, some people say that this error is because the file is too big, others say because file is corrupt, others say that it could be a not unix archive. So my question , how to find out if file is valid archive file on my Centos and what is the command/trick to uncompress big files ( if any ) Thanks in advance :)

• Looking for Firebird GUI

  - by EAMann

  I use phpMyAdmin to manage all of my MySQL databases and SQL Management Studio Express to manage my MS SQL databases. Now I need to start working with Firebird, and I'm looking for a tool along the lines of SQL Management Studio to manage those databases as well. I can be flexible with the UI and can learn a new system, so if there's something freely available that will do the trick but isn't quite the same as SQL management Studio I think I could adapt. Bottom line: What free tools are available that provide an in-depth GUI for Firebird?

• Subversion: Avoid proxy use on intranet

  - by l0b0

  I'm trying to exclude all intranet hosts from proxy use, but it looks like http-proxy-exceptions just looks at the command line string, not what the host name in the string resolves to. Because of this, it looks like the only way to avoid proxy use on the IP 123.456.789.012*, which also answers to vcs, vcs.example.org, svn, svn.example.org, subversion and subversion.example.org is to list all of them, not just the IP. Is there some trick to make Subversion either resolve IP addresses before checking for proxy exceptions, or exclude everything that is not a fully qualified DNS name (that is, doesn't contain a dot)? * Yes, I know that's not a valid IP

• Qemu in an ssh session or the quest for the nographic option ?

  - by LB

  Hi, I ssh to a machine and I would like to start a qemu session inside this ssh session. I thought that the nographic option would do the trick. -nographic Normally, QEMU uses SDL to display the VGA output. With this option, you can totally disable graphical output so that QEMU is a simple command line application. The emulated serial port is redirected on the console. Therefore, you can still use QEMU to debug a Linux kernel with a serial console. but unfortunately, i don't see any output. The command line that i'm using once i've sshed to my machine is : qemu-system-x86_64 -hda debian.img -nographic any idea ? thanks.

• linux/shell: change a file's modify timestamp relatively?

  - by index

  My Canon camera produces files like IMG_1234.JPG and MVI_1234.AVI. It also timestamps those files. Unfortunately during a trip to another timezone several cameras were used, one of which did not have the correct time zone set - meta data mess.. Now I would like to correct this (not EXIF, the file's "modify" timestamp on disk). Proposed algorithm: 1 read file's modify date 2 add delta, i.e. hhmmss (preferred: change timezone) 3 write new timestamp Unless someone knows a tool or a combination of tools that do the trick directly, maybe one could simplify the calculation using epoch time (seconds since ..) and whip up a shell script. Any help appreciated!

• Context Menu for Browser to download file to specific folder

  - by elcojon

  There is this website which has customized audio files for me. I would like to save them in a special folder. Now I don't want to select the "special folder" each time in the file-chooser dialogue of my browser. I would rather prefer to have a custom entry in the context menu when I right-click the download link. This context-menu-entry should do the trick and download the file to the predefined "special folder". How would I start about that? I am using Safari and Chrome. So a solution in either browser is fine. To get into the context menu of the browser, what kind of programming do I need to do? Is it an extension, plugin, etc.? Thanks

• Getting rid of GNU Emacs's menu bar in terminal windows

  - by Ernest A

  How to get rid of Emacs's menu bar in terminal windows? The standard answer is to put (when (not (display-graphic-p)) (menu-bar-mode -1)) in init.el. However, this solution is not good, because all it does is remove the menu bar after the fact. You can still see it for a split second. It's very annoying. Looking at the source code in startup.el I don't see an obvious solution to this problem. I think the only way is to use before-init-hook. Maybe this could do the trick? (add-hook 'before-init-hook (lambda () (setq emacs-basic-display t))) But this hook is run before init.el and other init files are evaluated, so how is one supposed to use it?

• Windows 7 Home Premium - Unable to View Chinese Characters Properly

  - by David

  Is there a proper and permanent fix that will restore the display of Chinese Characters on a Windows 7 Home Premium Laptop computer? This problem has been occurring frequently now and a simple reboot no longer does the trick. The square boxes viewed on many applications and websites has been constantly bothering me and I wish to fix it asap. I have done a lot of research on it but have not been successful. Many responses were to install the language packs for Windows 7 Ultimate Users which apparently is not my case or to configure the "Region and Language" settings of the Control Panel, changing the system locale. Does anyone have any suggestions? All would be appreciated!

• Thunderbird + Gmail, has to send emails twice.

  - by Mohammad

  I've configured Thunderbird to place a copy of my sent emails in my remote "sent" folder of my Gmail account as opposed to the local thunderbird one. This ensures I can completely take advantage of my imap synchronization. And so whenever I send an email, it first sends one to the address list, then it sends a new one to my sent box, however doing this with large attachments seems like a waste of time and bandwidth. Do you guys know of any extension or a combination of a trick plus a Gmail filter that could automate this in one step?

• application that could track amount of downloads

  - by user23950

  My ISP only limits me for downloading about 25gb a month. After exceeding the limit, my speed goes down by half for another month. And its really a pain. I'm real addicted on downloading stuff from the internet. My question is: Is there an application that can track the amount/size of downloads in a month. Is there a trick that I could use to fool the eyes of my ISP. If they say 25 Gb limit in a month. Does it include the webpages, manga streams, video & audio streams. Or just direct download and p2p.

• How to use MacBook Pro with external monitor / keyboard / mouse while running on battery only?

  - by Another Registered User

  I'm using my MacBook Pro like a desktop sometimes. But for some reason, when I unplug the Power Supply, it is impossible. The MacBook Pro immediately shuts off. When I turn it on by hitting any key on the external keyboard, it wakes up for about 10 seconds but then goes to sleep again. Sometimes I want to use my MacBook Pro without the Power plugged in to it, just to use the Battery a little bit. And also sometimes when someone else needs my Power Supply. I couldn't find an option in the system preferences. Is there an trick how to get that work?

• Is there a way to get the size of Outlook Calendar meeting items?

  - by bethlakshmi

  In our Exchange environment, our company caps the size of an Exchange account at a certain size. That size is the sum of all the exchange related stuff stored on the server - includign both the Inbox and the Calendar. I can tell with the Mailbox properties, Folder Size... window that my Calendar is a good 50% of my account's footprint. Is there any way to get a more detailed view of what meetings in the Calendar are taking up the space? Given the general pattern of incoming mail, it's my belief that 2-5 meetings are responsible for 75% of the memory consumption... I just need to find which meetings are the problem... and with my current calendar, it's a bit like finding a needle in a haystack. Anyone got a trick for this?

• mosh-like port forwarding

  - by Marc Merlin

  This is on linux, connecting to linux servers: I love mosh, but it doesn't support port forwarding, and likely won't for a while since it's been almost a year now and it hasn't happened yet. port forwarding over ssh is great, but because my laptop moves between networks several times a day, my ssh sessions die, and so do the port forwards. I could script/hack something to detect hung ssh and reconnect to get my port forwards back, but before I do this, is there another way to do long lasting port forwards when your source IP changes several times daily (because you go on different networks)? I'm thinking an ssh over UDP would do the trick but of course ssh is over TCP.

• Invoke host's workspace switcher from inside VM

  - by Paul

  When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

• IPsec VPN tunnel between Windows 2008 R2 and CISCO ASA?

  - by antur123

  I need to create a VPN IPsec tunnel between my Windows 2008 R2 server and a CISCO ASA device. I want my server to be both the end of the tunnel, and the server that connects to the other side (no need to connect a whole subnet, just the server would be fine). I found this article that seems to do the trick, but there are two differences: As mentioned above, the computer behind my end is the server itself. Can that be configured? (i.e. make the "computers in endpoint 1" IP address be the same than "local tunnel computer"). This article is for Juniper ScreenOS, not for CISCO ASA, though configurations look very similar. Would that configuration work for me?

• What type of amazon instance should I use and do I need auto scaling and load balancing?

  - by Navetz

  Hi I am looking to release a website that will initially have large amounts of uploads from users. The first will be 65GB and the rest will probably be close to 1TB. They could happen simultaneously. My question is what type of amazon server instance would be best for this? The website is just being released so the traffic wont be very high. I have been using a micro instance for development but it is time to launch and I need more power. Should I use auto scaling and a load balancer to increase the number of instances when I need it or Will a small or medium instance do the trick? If I do use auto scaling and load balancing how do I handle things like sessions and the database/file lookups? Does one instance become the primary instance and the rest become clones?

• Squid url rewrites https>>http

  - by bobfran

  I'm exploring some uses with Squid proxy 2.7 and I have seen a good number of examples for url rewrites that take urls such as: http: //somesitename.com and then the rewriter can change the url to: https: //somesitename.com And those examples work great. What I'm wondering though, is if its possible to do the reverse with a squid url rewriter. that is, to go from https: //somesitename.com to http: //somesitename.com ? Simply trying to edit the script file that handles the rewrites doesn't seem to do the trick. So I was wondering if there are some certain things I have to configure squid to do first, if its even possible to do what I am asking. I have my browser manually set up to have squid as a proxy for all requests and I can see https requests showing up in my squid access.log file (via the CONNECT method).
