• Command+Tab not working on MacOSX Client with Synergy

  - by dragonmantank

  I have an Ubuntu 11.10 laptop paired with an Apple Wireless Keyboard. I'm using the answer on this question to swap the Command and Option keys so that they are mapped like a regular keyboard. This works fine in Ubuntu. Now I have a Macbook Pro running as a Synergy Client. This mapping kind of works on the Macbook, but it only allows me to Command+Tab between two programs, not all of them. Copy, Paste, and other Command keys seem to work fine, but not Command+Tab. It's annoying just because I use the keyboard a lot. And yes, I could switch to syncing the keyboard and the Macbook, but I use the Ubuntu laptop more.

• What's Excel formats are (most) compatible with LibreOffice and Google Docs?

  - by iconoclast

  I use Excel (and occasionally Numbers), but I want to be able to share with users of Google Docs and LibreOffice (and I may want to switch in the future). What's the most compatible format to save my Excel spreadsheets in? I'm asking as a question here rather than merely Googling for a list of formats that LibreOffice and GoogleDocs support (although I'm doing that too, and will post the answer if no one else does) because there are likely to be hidden "gotchas" that only someone who has experience using all of the above applications is going to know about. Answers that include personal experience will be preferred over those that only post a link to the relevant facts on google.com and libreoffice.com. Oh, and of course the other reason I'm asking the question is because it's good to have this info readily available on SuperUser.com for anyone else who wants to know the same thing.

• Expression web ftp: Stuck at "Listing subsites"

  - by FrankPython

  When I try to use the Expression Web 4 built-in ftp I see the message ""Listing subsites in.." and soon afterward "passive ftp not available". If I switch to active, I get "active ftp not available". There are no subsites. It is a simple directory with one html page. Backend is a normal IIS6 server. FTP to the same IP with other FTP clients works fine! Any idea if Expression web has some specific requirements? It is our own dedicated server. (Please no tips to use another tool, for this specific project Expression Web is a requirement).

• How to get full write permission on my second drive after dual boot?

  - by Shaul

  I had a WinXP installation on my hard drive. Then I bought a 2nd drive and installed Win7. Dual boot working fine. But when I'm in the Win7 environment, it appears that I don't have full admin permission on the "D" drive (that's the drive with WinXP). Even though the user I'm logged in as has admin permissions, I have to run my apps with administrator privileges in order to get write access to the D drive. This is not the case when I do stuff on the C drive. I could just get into running those apps that access the D drive in admin mode, but that seems like overkill. Is there some secret switch I can flip so that my D drive acts like my C drive, security-wise?

• Colocation and HSRP setup

  - by WinkyWolly

  My colocation provider has setup HSRP for us and has provided us 2 drops (plugged into 1/1/1 and 1/1/2) from their routers as well as a /29 with 2 HSRP IP's and the rest of the /29 usable for the switch. I know that HSRP should be pretty much plug and play as long as the ports are in the same VLAN. However I'm confused as to how to the IP setup should work. Currently I've assigned port 1/1/1 the full /29 however I think this is incorrect because if I were to unplug it port 1/1/2 wouldn't work as it has no IP assignment. What's the proper way to do this?

• Mac Console.app not logging any messages

  - by karl_

  I recently attempted to overcome the 500 message limitation on console logs using the advice provided here: Mac: Extend or disable 500 Messages Limit of Console I copied the PLIST file onto my desktop, made the modifications, and re-copied into the LaunchDaemon folder. No dice. Unfortunately, this also broke logging in general- the console hasn't logged a message since I attempted this switch. I even went back and undid my changes. Still no logs. What's going on? Is there a way to reinstall Console.app, or revert to original settings?

• What is a quick way to access chrome extensions?

  - by Edward Tanguay

  I'm trying to switch from Firefox to Chrome, so trying to get up to speed with the interface. I have installed some Chrome extensions such as World Clock. To access it I have to: click wrench click tools click extensions on world clock, click "options" click save" and then I can use it. What am I missing here, there must be an easier way. Is there a way to just click something and have all my extensions in a dropdown, i.e. in one click? I couldn't find this on a list of chrome hotkeys.

• Quickbooks Error - Can't turn off auto updates

  - by Murtez

  My company uses quickbooks pro 2002 and unfortunately they won't upgrade at this time, the program keeps freezing and giving methe error: This action cannot be completed because this program is busy.. Then asks to switch or retry, I tracked it down to being an issue with IE since it's an old program and can't use the new versions of IE (the program uses IE for it's interface for some STUPID reason). Everyone says to disable auto updates but the problem is that I can't get to the options area to disable the updates (the options area uses IE!!!) so I'm screwed, I have to sit there and click retry 40-50 times several times a day and it's driving me nutz. I've been looking online for days but have not found a solution to this predicament. Is there a way to disable auto updates through the configuration files? Any help is greatly appreciated.

• Keyboard layout to shift wasd keys

  - by Joel Coehoorn

  I like to play video games on my computer. One of the things that bugs me, though, is how the wasd keys became the standard movement keys in first person shooters and mmorpgs. To me, esdf makes a lot more sense, because that matches your normal hand placement for typing. "Fixing" that layout is always the first thing I do when installing a new game. Sadly, this is often a pain in the neck, and some games won't let you do it at all. Is there an alternative keyboard layout you can install that will just switch these around, so the wasd keys fall in the esdf positions? And is low-level enough two work with DirectX/DirectInput, perhaps that works with the language bar for easy swapping back and forth?

• Downloading content greater than 2000 bytes from local network hangs in browser on Windows XP

  - by artplastika

  We have web application that runs under Tomcat in a local network. Our customers experience strange problem using this web application. Let's say Tomcat server runs on host1 and we open webapp URL in browser on host2. Any browser on host 2 starts opening page and downloading of content "hangs" for hours. We've made bunch of experiments and found that any content larger than 2000 bytes makes browser request hang. Tried in Internet Explorer 8, Opera 12, Firefox. At the same time if user opens website from internet, it works. Opening webapp from the same host1 where Tomcat is running works normally. Local network is organized with D-Link DGS-3120-48TC switch. Additional info. During experiments we've noticed XP Tweaker installed on hosts. Network settings from that tool: MTU is manually set to 1500 RWIN = 14600 Support of TCP frames larger than 64 KB is on Time to Live = 32 SACK is on

• win2003 server problem

  - by Tavo

  I used to have a server with win2000 OS. Yesteday I updated it to win2003 server R2 service pack 2. My problem now is that in a particular moment nobody can access the server. All of the shared resource of the server are unavailable. The only solution is to restart the server although the server is running fine. I don't think that is a connection problem of the LAN, because with the win2000 this problem didn't happend. The PC is connected to the same switch and the PC have the same exact hardware.

• Enterprise laptop doesn't recognize WiFi

  - by Michiel

  My cousin is using an enterprise laptop for home work, but for some reason she can't connect to her home WiFi. The laptop isn't able to detect any WiFi networks, although she used to be able to detect and connect to the network. Whenever I troubleshoot for possible issues, Windows Vista is telling me the switch for wireless reception is turned off, but I'm sure it's turned on (If I turn it on, the HP Wireless Assistant tells me it's turned on, so...). But if I take a look at the settings, I get this message (sorry it's in Dutch): So for some reason, the WLAN reception is deactivated and I cannot activate this... Does this have something to do with the laptop being an enterprise laptop? Or is there a simple setting I missed? The most recent driver of the Wireless Network Card (Intel Wireless 5100) is installed.

• How can I automatically lower Spotify playback volume when my Video Editing program makes a sound?

  - by Mark Major

  I'd like to listen to Spotify while I am video editing. This is just casual listening - nothing to do with the editing work. How can I automatically fade out the volume of Spotify when my video editing program plays audio? I often need to hear the video editing audio without the distraction of Spotify playing over the top, but the video editing playback is too on/off/on/off to switch Spotify audio manually each time. Without background music, I get really sick of the repeated playback of the audio clips with only silence inbetween. I suppose what I needd is an app that monitors sound output from 'App A' and reduces the sound output from all others (Apps B, C, D, etc) when something is played.

• Can I create a virtual network interface to connect to a real network device?

  - by michelemarcon

  I have a networked windows pc with 2 network interfaces. The first connects to a lan with ip address 10.1.. The second connects to another lan with ip address 10.2.. Maybe it's a dumb question, however is it possible to virtualize the second network interface, so that the pc can connect to the 2 lans? If necessary, I may switch to linux or paravirtualization. CLARIFICATION: I want to send DHCP broadcast packets on the second lan, but not on the first lan. I want to do it with one single physical network interface. At the moment, I'm not using any virtualization software.

• Network monitoring library, or objects, for a cloud

  - by Andrew Smith

  I am looking for library to support server / switch monitoring, to actually be able to check with the device if it's working OK. However this requires some sort of auto-detection and device support. Basically I need to automatically detect a new device, start monitoring it like CPU and PING. So how do I auto-detect the machine remotely, this is something I need library for. Rackspace has something like this - "Cloud Monitoring API". But is there anything opensource which can be used same way? The Nagios and others doesnt have such API, and the big and expensive systems are too big to handle in public cloud, so there must be some other network monitoring engine with API, which can add a new servers automatically and support user isolation for example so I dont see other servers except mine.

• Computer only booting after POWER ON/OFF 10 times or more?

  - by Jan Gressmann

  Hi fellow geeks, recently my computer started to behave like an old car and won't start up anymore unless I flip the power switch repeatedly. What happens when I power it on: CPU fans spins briefly and very slowly, then it stops Same with GPU fan No BIOS beeps or HDD activity Screen stays black After turning it on and off for like 10 times, it'll eventually boot like normal and run smooth without any problems what-so-ever. But I'm worried it might eventually die completely. Anyone know the most common cause of this? Maybe I should just leave the computer powered on? :)

• Can I change from BIOS IDE mode to AHCI mode at any time?

  - by Software Monkey

  Currently my Windows 7 computer is crashing during startup, after loading the AMD achix64s.sys driver, if I enable BIOS AHCI mode for the disks. It boots fine with IDE mode. Since I need my computer working, I am wondering if I can just use IDE mode for now, and later change to AHCI mode, when I figure out what is wrong. Background: I was running RAID mode, which needed additional drivers to install/boot Windows. But the MoBo RAID is flaky so I'm trying to switch to using a Windows mirrored volume instead - for that I expected to use AHCI mode.

• Nagios remote monitoring: NRPE Vs. SSH

  - by sam

  We use Nagios to monitor quite a few (~130) servers. We monitor CPU, Disk, RAM and a few other things on each server. I've always used SSH to run the remote commands, purely because it requires little to no additional config on the remote server, just install nagios-plugins, create the nagios user and add the SSH key, all of which I've automated into a shell script. I've never actually considered the performance implications of using SSH over NRPE. I'm not too bothered about the load hit on the Nagios server (It's probably over-speced for what it does, it's never been over 10% CPU), but we run each remote check every 30 seconds and each server has 5 different checks performed. I assume SSH requires more resources for each check but is there a huge difference? (I.E. enough of a difference to warrant the switch to NRPE). If it's any help, we monitor a mix of physical servers (Normally with 8, 12 or 16 physical cores) and Amazon EC2 medium/large instances.

• Can I mix CAT5 and CAT6?

  - by Jason94

  I'm thinking of upgrading the "backbone" of my network, taking a CAT6 cable from my router (DLINK DIR-655 (has cat6 ports)) to a gigabit swith in the tv rom (25m). I have two devices there that uses network (xbox and tvbox, both of them have cat5). Will my net be downgraded to 100mbit as max speed, or will I get 1 gigabit between my router and switch, and 100mbit between tvbox and xbox? From back in the days i have a tool to create my cat5 cable (the plug tool thingy), can I use this for my cat6 too?

• What are good and bad jitter times for a LAN

  - by garyb32234234

  Ive just ran jperf (frontend to iperf) on our network between 2 workstations, its recorded jitter between 0.033ms and 0.048ms. Is this good or bad? Are there more variables that i would need to consider to make the decision? EDIT: TCP/IP Ethernet LAN 43 PCs 1 server, 100Mbits main switch, various small 8 port switches, test was done using UDP, Its a Windows Domain. I want to instal a few voip softphones on the workstations, see how many i can use that reliably work, im testing a few different workstations around the network to see where the best quality network paths are. Will also change some equipment if i identify bad connections.

• Make laptop boot to external monitor

  - by Ozzy

  Hi all. Heres my setup: Dell 1737 2x Dell U2311H The laptop lid is always closed and is wall mounted behind the monitors. Every time i boot the laptop, i have to open the lid a little until it goes to the win 7 logon screen. Once there, i close the lid and both monitors get detected and the laptop screen switches off. As the laptop is wall mounted how ever, its really tedious to keep opening and closing the lid. Is there any way i can make it default to the external monitors permanently? Any suggestions are welcome, even hardware mods. Im willing to rip apart the laptop to install a switch or something if needs be lol

• DVI problem with LG L204WT

  - by Holgerwa

  I have a LG L204WT which has VGA and DVI connectors. Until recently, I have used the monitor via VGA, but now I have upgraded the graphics board and switched to DVI. The problem is that each time after the computer starts, the monitor either doesn't show anything (black screen, but doesn't go into standby) or the picture is distorted. I then switch the monitor off and on several times, and at some point it starts correctly and then I can work as usual. This only happens on startup. It is one out of 3 monitors, the other two work fine. It seems to me as if the monitor is not able to synchronize on the DVI signal and either shows a distorted picture or nothing at all. There are no settings in the monitor setup that would change anything. What could be the problem?
