  • change internet hotkey

    - by Matt
    My laptop (Acer Aspire 6930) has a hotkey to open the web browser. However, I just got Firefox and I was wondering how I can change the hotkey so that it opens Firefox instead of Internet Explorer. I already contacted Acer...they told me to phone them (at cost), which I would rather avoid since it's such a trivial matter.

  • VMWare use of Gratuitous ARP REPLY

    - by trs80
    I have an ESXi cluster that hosts several Windows Server VMs and around 30 Windows workstation VMs. Packet captures show a high number of ARP replies of the form: -sender_ip: VM IP -sender_mac: VM virtual MAC -target_ip: 0.0.0.0 -target_mac: Switch interface MAC The specific addresses aren't really a concern -- they're all legitimate and we're not having any problems with communications (most of the questions surrounding GARP and VMWare have to do with ping issues, a problem we don't have). I'm looking for an explanation of the traffic pattern in an environment that functions as expected. So the question is why would I see a high number of unsolicited ARP replies? Is this a mechanism VMWare uses for some purpose? What is it? Is there an alternative? EDIT: Quick diagram: [esxi]--[switch vlan]--[inline IDS]--[fw]--(rest of network) The IDS is complaining about these unsolicited ARPs. Several IDS vendors trigger on ARP replies without a prior request, or for ARP replies that have a target IP of 0.0.0.0. The target MAC in these replies is the VLAN interface on the switch. Capture points: -The IDS grabs the offending packets -The FW can see the same ones -A VM on the ESXi host does not see these, although there is an ARP request for a specific IP on the ESXi host that has source_ip=0.0.0.0 and source_mac=[switch vlan interface]. I can't share the captures, unfortunately. Really I'm interested in finding out if this is normal for an ESXi deployment.

  • Text to speech during IPhone call

    - by Jonathan
    Is there way to be able to type instead of speak during an iPhone call. For example when you text a landline (in the uk at least) the text message will be converted to speech. I would like to be able to do a similar thing in real time on my iPhone to another mobile. For example it would be useful for a mute person who can not speak to be able to "participate" in phone calls.

  • Slow and unresponssive network

    - by Jason94
    Ive have the Nokia N900 mobile phone (running Maemo linux), and my device is really slow while using the wifi and trying to get stuff online (checking mail, loading pages). The webbrowsers itself (MicroB, Firefox, Opera) starts fast. Yesterday ive tried to set the dns to googles but that did not solve the case. Is there, and how do i check/verify my connection to the internet if im connected to my home wifi in linux? (tools, other then ping :D)

  • Apache and MySQL not working well after extending filesystem

    - by xtrimsky
    I had 4Gb on my /var (/dev/mapper/vg00-var) filesystem, and I wanted to extend it to 160Gb. I did it following this tutorial: http://faq.1and1.com/dedicated_servers/root_server/linux_admin_help/7.html Now I have 160: Filesystem Size Used Avail Use% Mounted on /dev/md1 4.0G 424M 3.6G 11% / /dev/mapper/vg00-usr 4.3G 1.4G 3.0G 32% /usr /dev/mapper/vg00-var 198G 6.5G 192G 4% /var /dev/mapper/vg00-home 4.3G 4.4M 4.3G 1% /home none 1.1G 0 1.1G 0% /tmp Now I have a problem, in order for Apache to work, each time I reboot, I need to also reboot apache: "apachectl -k restart" which is already terrible.

  • Clicking far away in vim in tmux in urxvt

    - by paps
    I use vim inside tmux inside urxvt, and the mouse works perfectly well for clicking and selecting text, except when I want to click too far to the right. It seems to be related to the distance in number of columns from the left. When I go beyond column ~200 (not sure about the exact number), clicking simply does nothing. Note that it's not related to a vim window: with two vim windows taking ~150 columns each, clicking will not work after the ~50th column in the second window. It's related to the whole vim session. Also note that clicking far away in a big tmux pane (200 columns) works perfectly. In my .tmux.conf I have this line: set -g default-terminal "screen-256color" and in my .vimrc I have this: if &term =~ "^screen" autocmd VimEnter * silent !echo -ne "\033Ptmux;\033\033]12;7\007\033\\" let &t_SI = "\<Esc>Ptmux;\<Esc>\<Esc>]12;5\x7\<Esc>\\" let &t_EI = "\<Esc>Ptmux;\<Esc>\<Esc>]12;7\x7\<Esc>\\" autocmd VimLeave * silent !echo -ne "\033Ptmux;\033\033]12;14\007\033\\" end It changes the cursor's color depending on the editing mode of vim, and it works, meaning that tmux really sets $TERM to "screen-256color" — but I don't know if this has any relevance with my mouse problem. I'm running Ubuntu 12.04, vim 7.3, tmux 1.6 and rxvt-unicode 9.14. Does anybody have an idea about what is causing this problem? Thanks.

  • 7-Zip many files from different folders?

    - by mafutrct
    I would like to add a large number of files with different names from different folders to a single 7-Zip archive using 7za.exe. This should be simple, but it turned out to be a major pain. I created a file that contains the paths (7za a out.7z @list.txt), but once there are too many (~100) files, it fails. Apparently the content of the argument file is pushed onto the command line buffer [Edit: This was likely a misinformation on my part, either way it was not the reason], which is far too small (the number of files to add is more than one million). Splitting the process up by adding the files one by one is not feasible due to the way 7za works: When adding the next file, it creates a copy of the archive, adds the file to the copy and finally replaces the original. This is terribly slow once the archive gets to a couple 100 MB in size. So far I am using a combination of the two approaches by adding a dozen files each time in a loop, but it is an unreliable hack and still very slow. Is there a better way to do it? I tried to use 7-Zip wrapper DLLs (I'm a C# programmer), but none of them worked reliably and I was repeatedly suggested to just use 7za instead.

  • Multiple copies off the same printer on Windows 7 from PrintUIEntry

    - by Kev
    I currently have a number of bat files which work perfectly fine on Windows XP which install the same printer multiple times with a number of finisher options set - e.g. after running the bat file below I would end up with four printers in the printer drop down called Sharp Kits Printer - A4 Single Sided Sharp Kits Printer - A4 Single Sided Stapled Sharp Kits Printer - A4 Duplex Stapled Sharp Kits Printer - A4 Duplex which all have there options configured in the relevant way. I have amended on Windows 7 to point to correct INF file and printer name in the INF files - a single printer installs fine. However when I run the complete batch file only the first printer in it is installed - occassionally the later ones flash up in the GUI but then vanish when you press F5 and are still missing after a reboot. SET QUEUENAME=http://192.168.7.123:631/printers/Sharp700 SET PPD=J:\DRIVERS\Printers\MX700-Win7-64\SJ1JWENG.INF SET PPDENTRYNAME=SHARP MX-M700U PPD J: cd "\DRIVERS\Printers\MX700-Win7-64" SET NICENAME="Sharp Kits Printer - A4 Single Sided" SET PREFS="J:\SCRIPTS\Printers-Win7-64bit\Sharp_SINGLE_SETTINGS.dat" %SYSTEMDRIVE%\WINDOWS\system32\rundll32.exe %SYSTEMDRIVE%\WINDOWS\system32\printui.dll,PrintUIEntry /w /b %NICENAME% /x /n "part of the n switch" /f "%PPD%" /if /r "%QUEUENAME%" /m "%PPDENTRYNAME%" rem restore settings go here...

I have tried adding the "/u" paramater to the end, I have changed the "/n" paramater to be different (e.g. n1, n2,n3 etc) - both of these result in the same. I have also tried to change the port (/r) to have "_1" (etc) on the end like the GUI would but this errors as the port doesn't exist. Is it possible to do this on Windows 7, and if so how?

  • pdns-recursor allocates resources to non-existing queries

    - by azzid
    I've got a lab-server running pdns-recursor. I set it up to experiment with rate limiting, so it has been resolving requests openly from the whole internet for weeks. My idea was that sooner or later it would get abused, giving me a real user case to experiment with. To keep track of the usage I set up nagios to monitor the number of concurrent-queries to the server. Today I got notice from nagios that my specified limit had been reached. I logged in to start trimming away the malicious questions I was expecting, however, when I started looking at it I couldn't see the expected traffic. What I found is that even though I have over 20 concurrent-queries registered by the server I see no requests in the logs. The following command describes the situation well: $ sudo rec_control get concurrent-queries; sudo rec_control top-remotes 22 Over last 0 queries: How can there be 22 concurrent-queries when the server has 0 queries registered? EDIT: Figured it out! To get top-remotes working I needed to set ################################# # remotes-ringbuffer-entries maximum number of packets to store statistics for # remotes-ringbuffer-entries=100000 It defaults to 0 storing no information to base top-remotes statistics on.

  • Can't Connect SQL server - process being used by another process. Conflict with IIS?

    - by shinya
    I'm having problem connecting to MS SQL Server (2012 Express) after accessing a database through IIS (web site). I can access the data through web site no problem, but I can't access the data from any other programs (i.e SSMS) until I reboot the SQL server. It seems that the connection stays open even if I close a browser. Here is error message I'm getting Unable to open the physical file "C:---------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Unable to open the physical file "C:-------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Cannot open user default database. Login failed.

  • How to resume XMPP groupchat window in Irssi (using bitlbee)?

    - by mcnesium
    I use Bitlbee to chat in XMPP-networks within my IRC-client Irssi. This works great so far, and recently I started using XMPP Multi User Chats as an alternative to IRC-channels. I set up a channel using chat add <account> <[email protected]> in the &bitlbee control window, set chan <room> set autojoin true and entered /join #room in the &bitlbee window to join that groupchat. It then appears as a unique Irssi window in the status bar. This seems to work ok too, but with one exception: Since I idle in the channels 24/7 my irssi has to cope with the every-night-24h-DSL-disconnection by the ISP. After it automatically reconnects, it does kind of rejoin that XMPP-groupchat, but the traffic of the groupchat does not go back to the unique irssi window, but keeps flooding &bitlbee with messages from root telling me about a Groupchat Message from unknown JID <jid>: <message> - which is the traffic of the groupchat. The unique groupchat window is gone after the reconnect, and I will again have to go /join #room in &bitlbee to get it back. Even worse, the window number is unused before I rejoin the groupchat, and if I get a query from any network, the window nests in that unused window spot, so I will first have to remove that query from the spot, and then move the rejoined groupchat to that window number. I want my groupchat window to resume after the reconnect just like every other IRC channel too. How can I get this done? Any ideas?

  • Howto align partitions in Linux + NetApp

    - by santisaez
    NetApp support has suggested us aligning partitions to improve performance, in short: starting sector must be divisible by 8. How can I move the start point in a misaligned partition -in production, with ext3- under Linux? A screenshot with a misaligned (start=63s) and aligned (start=64s) partition is available at: http://filesocial.com/lkwvvn2 (If anyone is interested in this topic, NetApp has a good document explaining performance issues in misaligned partitions, search for "tr-3747": Best Practices for File System Alignment in Virtual Environments.) I have tried using parted "resize + move" commands, but when moving start point a get this error: (parted) resize Partition number? 1 Start? [64s]? End? [419425019s]? 419425018 (parted) move Partition number? 1 Start? 65 End? [419425019s]? 419425019 Error: Can't move a partition onto itself. Try using resize, perhaps? Using fdisk 'b' command in expert mode ('move beginning of data in a partition') works, but it doesn't move the file system.. thanks!!

  • How to use the outcome of a formula as the value for Vlookup or another IF formula

    - by Steven
    Ok I will try to explain my issue effectively. I am making a GPA sheet in which the value out of 100 is computer in to a GPA value and then in to a letter. In cell N5 i have the value of all their grades (formula: =H3+H4+H5) Now in cell (j6) I have a formula which is giving them a number depending on the value calculated in N5 (Formula: =IF(AND(N5>=60,N5<=63.999),"2.0",IF(AND(N5>=64,N5<=66.999),"2.25",IF(AND(N5>=67,N5<=69.999),"2.4",IF(AND(N5>=70,N5<=73.999),"2.5",IF(AND(N5>=74,N5<=76.999),"2.75",IF(AND(N5>=77,N5<=79.999),"2.9",IF(AND(N5>=80,N5<=83.999),"3.0",IF(AND(N5>=84,N5<=86.999),"3.25",IF(AND(N5>=87,N5<=89.999),"3.4",IF(AND(N5>=90,N5<=93.999),"3.50",IF(AND(N5>=94,N5<=96.999),"3.75",IF(AND(N5>=97,N5<=100),"4",IF(AND(N5<=59.999),"0"))))))))))))) Still no problem... as the values I was looking for comes out (example 84.2 shows up as 3.25 as I wanted). However here comes the problem.... I have tried to use the outcome in J6 to do Vlookup or another if formula, however excel does not seem to recognize the value in J6. For example: =VLOOKUP(j6,B3:C15,2,FALSE)... this returns N/A however if I enter =VLOOKUP(3.25,B3:C15,2,FALSE) it gives me what im looking for. It seems that excel will not register the outcome of my formula as a number. What can I do please?

  • My computer makes weird sounds that you can only hear through a speaker

    - by Mury
    I recently got a brand new computer. Everything was fine until I plugged my electric guitar into my amp. When I switch on my guitar amp (guitar speaker) I can hear a weird noise. It sounds like the noise that that goes through your speakers when you put your mobile phone next to it. There is nothing wrong with my guitar or guitar amp and I didn't have any similar problems with my old computer. Can anyone help me?

  • Repair Windows 2008 boot

    - by aksamit
    I have been caught in a loop where I can't boot up Windows Server 2008. When the OS starts to boot I am presented two options: Launch Startup Repair (recommended) Start Windows Normally No matter what option is chosen I end up with a black screen stating "Windows is loading files..." which takes approx 15 minutes until "System Recovery" is started. I try to run the "Startup Repair" but it reports the following error: Problem Event Name: StartupRepairOffline Problem Signature 01: 0.0.0.0 Problem Signature 02: 0.0.0.0 Problem Signature 03: unknown OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033 Actually no matter what other options I would try in the System Recovery they would also report some kind of error. Some other logging I have been able to extract: Diagnosis and repair details: Number of repair attempts: 1 Session details System Disk = Windows directory = AutoChk Run = 0 Number of root causes = 1 Test Performed: Name: System disk test Result: Completed successfully. Error code = 0x0 Root cause found: A hard disk could not be found. If a hard disk is installed, it is not responding. So it is actually stating that Harddisk could not be found... which to me seems to be a bit contradictious since the System Recovery just loaded all files from the hard disk it now states it cannot find. Any ideas on what other options I have?

  • New AD user request form and workflow

    - by user66390
    I'm wondering if anyone is providing a solid solution for creating New Network User Account Request forms, and attaching workflows to them to automate account creation? I'm currently investigating a number of options, but am surprised that such a ubiquitous task hasn't been solved a dozen times over and thoroughly documented. Or at least isn't integrated into current off-the-shelf change management and ticketing systems. Ideally, I'd like for our current ticketing system, ServiceDesk+ to present a standard 'New User' form to department heads, which they can fill in with the required new user details. This triggers a workflow that submits the request as a ticket that can be reviewed and actioned. Actioning the ticket triggers a workflow that creates a user in AD with the details provided, and notifies the department head upon completion. All told, a pretty standard requirement that I'm sure most organizations have. What are other people doing to accomplish this? Edit: I should add, I'm more looking for "supported" methods. As is, I've submitted a number of scripted solutions, none of which have met with manager approval.

  • virtual host settings fail on multiple sites

    - by Ricalsin
    Wow. I'm puzzled. On my ubuntu system I've setup an apache2 server and configured three virtual hosts in the /etc/apache2/sites-available directory. a2ensite to symbolic link the sites-enabled. The first two work great; a simple url of localhost.mysitenames.com works great for the first two sites, both finding their DocumentRoot and Directory paths. The third always generates a Bad Request (Invalid Hostname) response. No server error.log as it never hits it. I've copied/pasted the working vhost files, made the minor changes to the ServerName, DocumentRoot and Directory and the same problem persists. I always "sudo /etc/init.d/apache2 restart" whenever I make a change. I've cleared the browser cache as well. No love. There's not a limit to the number of sites you can host, right? My goal was a localhost development environment with the expectation I can run any number of websites locally before pushing them to a live server. Any thoughts on how to debug this? Or, just a simple solution I am missing?

  • How to resolve 'No internet connectivity issues' with a Virtualised 2008 R2 Server using Forefront UAG

    - by user684589
    I have spent some considerable time reading up on as many possible blogs and articles as I can to help me solve why my VM (Running on Hyper-V) for DirectAccess has suddenly stopped being able to access the internet. The VM setup shares the same internet connection on which I have written and submitted this question so I know that the actual underlying internet connection is fully functional. Previous to last week the DirectAccess was fully functional and had no issues. This is a recent problem which was led up to by a number of consistent crashes on the DA machine when access was attempted. Upon reboot all seemed well until recently. I am not certain whether it is relevant, but previously to this I had a number of power issues where the entire VM host shutdown unexpectedly leaving around 8 VM's in a bad way. Upon restart, the UAG DirectAccess machine was unable to access its configuration service (although the service was started) but this seemed to relate to the Light-Weight Active Directory Service AD LDS which had a corrupted database. Having repaired this database, I restarted the service and could subsequently reconnect to the configuration service again. For good measure I re-bound the network adapters (virtualised through Hyper-V) and DirectAccess claimed to be all happy again. However as it stands my machine is still unable to access the internet showing the "No internet connectivity" exclamation mark for the external facing NIC. I have also tried removing the adapters, disabling, re-enabling and the problem persists. The intranet part of the VM CorpNet seems to be fully functional as before and I'm running out of ideas. Any input would be greatly appreciated. I am not an advanced Domain Administrator so please be gentle.

  • Is it possible to trace someone using Google during an online exam?

    - by George
    I happen to be a professor at a reputed college. I want to design an online exam for over 1000 students via around 50 computers right after the vacation ends. Now the problem is that I have heard that many students use Google on a different tab to find answers when no invigilator is around. I want to know if there is a way to backtrace it after the exams via some kind of history or any other possible way. In our university there is a standard system. I am not good with computers but I will try to explain. Each computer uses mozilla to connect to a server centrally located via an IP. The students open it and enter a unique ID and password to start the exams. Many questions are jumbled and different groups of students give exam in a different time slot. Is there any way to trace it since I want to set an example for students so they won't cheat and give exams in an honest way. Additional details: Since the number of computers are less than the number of students, more than 10 students are going to use a single computer on a single day over a period of 10 hours. After this, if I check the history (and let's say someone even forgot to delete the history and I see it), will I able to figure out who among the 10 has done it? Moreover, is it even practical and feasible?

  • Server 2012 - transparent SMB failover without shared discs, possible?

    - by TomTom
    here is the scenario - there is a small set (200gb around) of data that I HAVE to keep available. Those are basically shared VHD images that serve as master images for a lot of our VM's - they then run in differential discs off those. The whole set is "mostly read only". In more detail: A file that IS there and IS used will NEVER change. I may delete files (when absolutely not in use) and add new files, but a file that is there once gets read protection set and that it is until it is retired. Obviously, I need as much uptime as possible. SO FAR we run that by having this directory local on every Hyper-V server. Now I think moving this into our storage fabric. Due to the "it HAS to be there" I pretty much want a share nothing architecture. DFS would be perfect for this - a file never changes, so replication would work nicely. Folders could be replicated to a number of servers, all would reference them from there. Now, that hyper-V supports SMB that could be a good idea to isolate these on a number of servers - we try to move into a scenario where the storage is more centralized. Server 2012 supports always on shares, but it seems that this only works with a clustered disc behind. Is there any way around this for read only file stores? All documentation points to stuff like a shared JBOD - but that would leave me open for file system corruption. I really plan to go quite separately here, vertically - 2 servers, both with SSD only for this, both with their own 2000W separate USV, both with enough bandwidth to handle everything thrown at them (note to everyone tinking this is 10G - this would be SLOW and EXPENSIVE compared to a nice Infiniband backbone). The real crux is that this is an edge case obviously - as the files are read only once in use.

  • Disk fragmentation when dealing with many small files

    - by Zorlack
    On a daily basis we generate about 3.4 Million small jpeg files. We also delete about 3.4 Million 90 day old images. To date, we've dealt with this content by storing the images in a hierarchical manner. The heriarchy is something like this: /Year/Month/Day/Source/ This heirarchy allows us to effectively delete days worth of content across all sources. The files are stored on a Windows 2003 server connected to a 14 disk SATA RAID6. We've started having significant performance issues when writing-to and reading-from the disks. This may be due to the performance of the hardware, but I suspect that disk fragmentation may be a culprit at well. Some people have recommended storing the data in a database, but I've been hesitant to do this. An other thought was to use some sort of container file, like a VHD or something. Does anyone have any advice for mitigating this kind of fragmentation? Additional Info: The average file size is 8-14KB Format information from fsutil: NTFS Volume Serial Number : 0x2ae2ea00e2e9d05d Version : 3.1 Number Sectors : 0x00000001e847ffff Total Clusters : 0x000000003d08ffff Free Clusters : 0x000000001c1a4df0 Total Reserved : 0x0000000000000000 Bytes Per Sector : 512 Bytes Per Cluster : 4096 Bytes Per FileRecord Segment : 1024 Clusters Per FileRecord Segment : 0 Mft Valid Data Length : 0x000000208f020000 Mft Start Lcn : 0x00000000000c0000 Mft2 Start Lcn : 0x000000001e847fff Mft Zone Start : 0x0000000002163b20 Mft Zone End : 0x0000000007ad2000
