• How to stop iPhone's safari browser from silently dropping tabs when you open a 9th tab?

  - by MattH

  Currently in the iPhone safari mobile browser, if you have 8 tabs open and open a new tab, the new tab opens as requested, but one of the existing tabs is silently discarded. Is there any known way to change this behaviour, e.g. to prompt me first and allow me to choose which tab to close, or to open the 9th tab, or to at least have visibility of what tab was closed? When I open something in a new tab it's because I want to come back to the previous tab later, so this conflicts with the way I usually browse the web. My current workaround is to manually monitor the tab count -- i.e. to check that the count is 7 or less before opening a new tab.

• how to install daemontools (supervise) on centos 5?

  - by solsol

  I'd like to use supervise to monitor httpd, mysqld and hudson processes on Centos 5. When any of these processes go down I'd like to use a tool to automatically restart them. I've read and heard about supervise, but couldn't find a way to install it on centos. Can anyone help me with that? Any other tools are also good, as long as they can be easily installed on centos 5 and allow me to automatically restart httpd, mysqld, hudson. Thanks for your help!

• Monitoring several remote servers over different VPNs

  - by Ciaran

  I'm a developer with about 20 different clients running our server application. I access each of the clients' servers remotely through VPN to provide support, updates, etc. Is there any tool available that I can set up locally that will connect through each of the VPNs automatically to allow me to monitor? The idea sounds very far fetched to me as the VPN software varies a good bit but maybe someone's had to do something similar before? It's been a few years since I last used Nagios but I think it'd be quite cool to have that set up pointing at each of the remote servers through VPN somehow.

• Lenovo G530 laptop screen flicker

  - by Kevin

  I have a Lenovo G530 laptop that has an issue with screen flicker that is getting worse. The computer screen will start going thru a crazy screen flicker then will stop and start again. I have already checked cable connection to lcd on motherboard and reseated connection as someone suggested in another posting I found online that resolved issue. I am starting to think it might be a bad inverter or screen because I have hooked up laptop to external monitor and it is running fine with no flickering happening when the flickering is occurring on laptop. I am attaching a link to a small video I shot of the issue as it is occurring on laptop screen. Does anyone have any further suggestions? Bad inverter or screen? Screen flicker vid

• Dummy SMTP server as a service

  - by levidos

  Hello, I have a Windows Server 2008 machine with IIS installed which is hosting a webapp that is sending some notification mails once-in-a-while. What I'd like to do is to monitor the email sent by the application. For this I need a dummy SMTP server which intercepts messages but won't send them further but save them locally on the hard disk.I've already found some of them like Papercut, SMTP4Dev. The problem with these that I have to be logged on the server all the time which is not suitable because the server has only 2+1 TS connections. I like to run a program like these as a windows service and check the mails when I need them. Any suggestion is much appreciated. Best Regards,Levente Rog

• gltail “Missing gem net-ssh”

  - by Ian

  I'm attempting to get gltail set up on my local system to monitor logs remotely. I've got all the dependencies installed, but when I go to run gltail ... ./gl_tail configfile ../config.yaml I get this output: Missing gem net-ssh. Ubuntu: sudo gem install -y net-ssh -r .. which I've done a number of times.

• How do I tell if my Windows server is swapping?

  - by churnd

  I'm using Process Explorer to monitor my windows server while it reconstructs some data. It's primarily a CPU intensive process, but I want to make sure it's not swapping. How can I tell if it is using Process Explorer? My initial guess is in the System Information window, it's Paging File Write Delta. Yes? No? I'm an idiot? *Screenshot is not of the server... just an example.

• Bios wont post unless I restart power supply.

  - by remy

  I have an annoying problem with a computer. The BIOS wont post after it has been turned off and started again unless I turn the switch off/on on the power supply. The fans, cdrom hdd and everything starts running but the bios never beeps and the monitor stays black. I HAVE TRIED: reinstalling windows xp, flashed bios to latest, cmos clear, new power supply, other hdd, new memory sticks, graphics card. I also removed the motherboard from the computer case and laid it on a cardboard box and only connected the PSU, RAM and CPU. Other than this the computer works great but its annoying having to off/on the power supply switch before turning it on after its been off. My guess is that the motherboard is faulty but I would just like to hear what you guys think. Sorry for my english / Remy

• Several devices in Device Manager have Code 3 error

  - by John Straka

  One of our users' machines (Dell Optiplex 380 running Windows 7 32-bit) is having a weird driver issue. A bunch of devices have Error Code 3: The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3) The system isn't low on memory (only 1GB in use out of whatever the max for 32-bit is.) Here's a screenshot of the affected devices: I tried reinstalling the chipset and audio drivers to no avail. I have no idea what prompted it, and I'm not sure how the basic Windows Generic PnP Monitor driver could even be corrupted. What might be causing this error?

• How much power supply do I need for my server, and could a shortage be causing my odd crashing?

  - by dolan

  I have 5 servers, all with similar hardware (i7, four 2tb 7200rpm drives, two 4tb 5400rpm drives, 430 watt power supply), and lately the machines have been freezing up. This has gotten worse in the last day or so, and I can't pinpoint any explanation. One recent change was adding the two 4tb hard drives. The crashes happen most often while running a large Hadoop job, so I was originally thinking the load was causing some issues, but last night one server just froze without any heavy load on the box (or so I think), other than HDFS (Hadoop's distributed file system) was probably rebalancing itself since two of the five nodes were offline. If I plugin a monitor and keyboard to one of these frozen machines, I can't get any response or feedback on the screen. Any ideas on possible points of failure and/or different logs I can look at to investigate? Thanks Edit: The systems are running Ubuntu 10.04 Edit 2: More on hardware: intel core i7-930 bloomfield 2.8ghz processor (quad core) 12gb (6 x 2gb) kingston ddr3 1333 ram antec earthwatts green 430 power supply msi x58m lga 1366 motherboard

• Why does my iTunes use so much CPU time?

  - by bikesandcode

  I have a roughly 2 year old Macbook (10.5). I have iTunes 10. When iTunes is playing MP3s, I see CPU usage of the iTunes process in the system monitor ranging from 65%-75%. When I pause the music, I see CPU usage of about 65%-75%. I do not have any visualisations going, to my knowledge I have not turned on any CPU destroying features, my music library isn't tiny, but it's hardly huge (3GB). This is mildly annoying when I'm plugged into the wall as I only have slightly longer compile times, but if I am out and about, this is a major drain on the battery. Using VLC I see CPU loads of ~= 10% at the most when listening to music and generally lower. What the heck is iTunes doing?

• Access console of QNX server

  - by dhergert

  I am new to QNX (although I am familiar with Unix/Linux). This company I am working with has an old QNX (4.25) server in a server room that they remotely access via Windows terminals (Kermit via Telnet) which presents them with a text-based program. I need to get into/onto the actual box to be able to view directories, files, etc... and wondering if I can do that "remotely", along the lines of how I would SSH into a Unix box. Is there something like that in QNX? Do I need to actually hook up a keyboard/monitor to this server to be presented with a console? Would I even get a console?

• List and kill running processes on Mac OS in Ctrl/Alt/Delete-like way?

  - by AP257

  So, what do you do on a Mac when a process (as opposed to an application) is hogging CPU, swamping your machine, and you need to kill it? I know you can use top or open Applications > Utilities > Activity Monitor and kill it from there. But what happens when the process is already using so much CPU that doing either of those tasks is impossible? On Windows, you can just do Ctrl/Alt/Delete and the process list will reliably open. So no matter how much your computer is thrashing, you always have access to the list of processes. On Mac OS, there's Cmd/Alt/Escape, which reliably shows running applications. Fine when it's an application causing the problem. But: what do you do if it's a process?

• Cascading KVM switches

  - by einpoklum

  I have a not-so-small number of computers (say, 5) which I want to access with a single keyboard, USB and monitor. I can get an 8-port KVM switch, which is a pretty expensive piece of hardware; however, in theory, I should be able to cascade KVM switches: Have one 4-port KVM switch between 2 other KVMs (a 2-port and a 4-port). Is this doable (with typical off-the-shelf switches and cables)? Has anyone had experience doing this? Note: I'm interested in USB-only for the keyboard and mouse, and either VGA or DVI for the display. Audio and PS/2 connections are irrelevant for me..

• MS-DOS application sending screen output to LPT printer

  - by gadget00

  We have a MS-DOS application(coded in FoxPro), and recently had this glitch: the screen menu of the application without reason starts printing in an LPT Panasonic KX-1150 printer. It's a never ending print of all the screens of the application, as if the main output instead of sending it to the monitor, sends it to the printer! It creates a unnamed document with N/D pages and keeps printing forever. We have to turn the printer off and then kill the document in the spool to stop it... The printer is installed with a Generic/Text driver, and has happened to us both in WindowsXP and Win7. What can this be? Thanks in advance

• Gnome - windows always open top left

  - by BobTodd

  I find this a highly annoying "feature" on a wide screen monitor that my mostly used apps - terminal and gedit always open directly under the top-left corner of my screen and I have to drag them to my eye position each and every-time. I have tried installing the CompizConfig Settings Manager and using the feature to position windows centre, but this has had no effect - the force feature here isn't working for me either. I can use e.g. gnome-terminal --geometry=140x50+50+50 for the terminal but this doesn't work for gedit. Any ideas? Thanks

• Why do I have no TTY on a basic Ubuntu 9.10 server install?

  - by pr1001

  I have reinstalled Ubuntu 9.10 Server several times on a bog standard 1RU server and each time I finish the install and reboot I see GRUB run and am then presented with a black screen. The machine is running just fine, as I am able to SSH in, but I can't see anything on the attached monitor. I have a simple LCD screen connected via VGA and a signal is apparently being output to it, as it doesn't go asleep. Looking at /var/log/syslog I see: Mar 24 14:57:44 bridge5 rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ] However, I later see: Mar 24 14:57:44 bridge5 kernel: [ 0.001368] console [tty0] enabled Any thoughts? Thanks!

• HD Radeon 6950 cannot run multiple monitors

  - by Bryan S.

  I'm having troubles getting multiple monitors to run on my graphics card. I plug one via the hdmi, and one into the DVI (I have tried both available DVI ports). with one DVI port it does not even register the monitor, with the second one I go into the Catalyst Control Center and it gives me the option to swap between the HDMI and the DVI port. I guess since this is the flex edition I could just go get 2 DSP to HDMI converters, plug 2 monitors in through the available DSP, and than the 3rd one into the HDMI, but do you have any idea why it will not let me run one HDMI and one DVI?

• Proxy Server suggestions

  - by Jon Menefee

  Here is the question I have that hopefully is not too general of a question. I have a network with approximately 25 PC's, 3 servers and 25 IP cameras. I have a firewall already on the network and it works fine for what I need, but my client is asking me if there is a way to put a Proxy server on the network to monitor where his employees are going when they surf the Internet. He is not wanting to block them (at least not thru the Proxy server), but he wants to make sure that they arent going to sites that would compromise the networked PCs. I have looked at TMG and it is a little more than what I want. I hesitate adding another firewall to the system because of the security cameras that are presently on the network (IP Cameras). I just want to put a policy in AD that would make certain Users (or Computers) use a Proxy server. Any suggestions on a good proxy server are welcome. Thank you

• How do anti-viruses work?

  - by Phoshi

  So I was thinking about viruses recently, and wondering how exactly antiviruses keep up? Considering anybody who'd been coding for a few weeks could hack together something do do nasty, nasty things to somebody's PC, the quantity alone would make a simple list of hashes prohibitive, so how do antiviruses do it? Do they monitor process activity and have a 3 strikes rule for doing virus-like things? And if so, what's stopping it from triggering on perfectly harmless things (like me moving files around in \system32)? I did a bit of googling, but the regular places didn't particularly help, and I couldn't find a dupe here, so I thought it'd be good to ask :)

• Frame rate upsampling codec/player/software?

  - by djechelon

  Hello, I recently noticed that when I play both HD and SD videos on my HDMI TV at 1080p 60Hz from my computer, the motion is not fluid as I would expect. As far as I know, it could be because the 24fps video needs to be upsampled by the codec to match the 60Hz output of the monitor. But, as far as I know, the upsampling is done by simply repeating each photogram for a certain amount of frames. I usually play MKV videos with VLC. Do you know if there is a player or codec that performs the upsampling by interpolation like some 100Hz TVs do? I recently saw an LG led TV play a 24fps 720p video at 100Hz with an incredible motion fluidity, and I simply wonder why can't my computer do! I have an NVidia card. Does PureVideo help? I'm a noob with these things. Thank you.

• Why is Chrome receiving data?

  - by Aero

  Chrome seems to be continually receiving data even though I'm not downloading anything. This is making a noticeable impact on my browsing speed. The first screenshot shows Chrome receiving data even though I'm not downloading anything (nor buffering a YouTube video etc.) Even after I completely close Google Chrome, the "chrome.exe" remains in the Resource Monitor list and the "Received bytes" column continually increases in the screenshot below. However, "chrome.exe" does not show up in the Processes tab of Task Manager. This only occurs sometimes, but I don't know why. I have tried running a malware/virus scans to ensure that there is nothing malicious behind this, but those scans have shown nothing. Any ideas on what's causing this?

• Can't open Control Panel or IE

  - by Josh

  I have a XP computer where when ever I try to open Control Panel nothing happens, nothing flashes on the screen. Same thing with Internet Explorer. I've scanned the computer with Malwarebytes and Avast, Malwaresbytes found some Adware which it removed without problems. Avast found nothing. I looked at the running processes with Process Explorer, nothing malicious running. And looked at a Process Monitor output when I tried to run IE, nothing obviously wrong. The process just decides to exit. What can I try next? I would suspect corrupt IE install but Control Panel doesn't work either. UPDATE: Nether work in Safe Mode under the user account. (only 1 user on the computer) But in Safe Mode, under the built in Administrator account, they work. So what ever is broken, is only broken in the one account. Anything under the HKCU registry key that could break this?

• RDP locks up login, doesn't unlock on Windows

  - by private_meta

  From time to time, my system, when I try to login TRHOUGH or AFTER a remote connection, locks up the login session. I can't login anymore, the screen turns black (the monitor is still active, the image is black). Especially in the recent case, the system did not come back from the lock-up, and I had to reset the computer. Any idea what might be the issue here? More information: Both Computers are Windows 7, The RDP Server has a wired connection, the Client has either Wireless or Wired. The network card involved on the server is a "Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)" card built-in on an ASRock Mainboard. I'm using either local LAN or internet connection through NAT/Router.

• Remote desktop solution for controlling a remote OS X machine in Linux

  - by synic

  The "server" (the host I'm trying to connect to) is Snow Leopard. The "client" is Ubuntu 10.04. I want something like a remote desktop server running on OS X that I can connect to and control from the Linux machine. Something cheap or free would be best. Something that always runs on the OS X machine so that I never have to attach a monitor or a keyboard. I don't want to use VNC, because, well, VNC sucks over this network. Any ideas?
