  • Server suffering serious speed drop

    - by Tar
    As you can see from the picture http://i.imgur.com/UpDZh.png), my server is suffering a serious drop in speed. This is intermittent and has been happening for the past 3 or 4 hours. The server has 1gbps uplink so I can't figure out why it's happening. Checking bandwidth monitoring tools like bwm-ng and dstat show normal speeds of like 150kb/s outbound traffic. Just now I was completely disconnected from SSH.

  • I need to create a volume/symbolic link from a UNC Path

    - by Sebas
    I have a workstation with Windows XP and I need to make a symbolic link or mount a UNC Path like a local Drive. I need the same behavior that produces M-Daemon tools when you mount an .iso File but with a remote directory. This is because I have a software client that perform several task but only with local drives and directorys. The remote UNC path is a NAS server, thats the why I need to perform all the tasks from a workstations. Thanks a lot!

  • What "pieces" are needed in order to set up a cluster of physical servers?

    - by Chris Dutrow
    Background: Currently, we use Rackspace cloud servers. We have no intention to stop using them, but would like to look into setting up a cluster of physical servers (probably desktop computers in the $400 range with 8gb memory each) to offset some of our load and work as a secondary, more powerful, less reliable system. To put things in perspective, we can buy comparable desktop computers for the same price as we pay in one month to rent them on Rackspace Cloud. I understand that this is generally a dumb idea. However, in this particular instance, the server cluster is needed for its computation power. It is not mission-critical, it does not host a consumer-facing website, and if it goes down for a day or two, its not really a problem. Currently, we have access to business class verizon fios. If I understand correctly, we can get at least 25 dedicated IP addresses with this service, this should be enough. Requirements: Each server runs Linux Centos 6.3 Some of the servers run Python and execute processes from a task queue (Redis or RabbitMQ) Some of the servers are capable of serving static files and Python driven REST APIs Some of the servers host a Cassandra database cluster One or more of the servers are a Redis database servers One or more of the servers are PostgreSQL servers Questions: What kind of router or switch is needed? We would like the computers to be able to communicate effectively with each other via internal IP addresses. This is especially important for communicating with servers hosting Redis that need to be able to respond to requests very quickly. Are there special switches or routers that need to be used to connect the servers together? Are Desktop computers ok for this? We have found that we are mostly RAM-bottle necked, I understand that some servers have highly superior CPUs, but I'm not sure we need CPU power as much as we need RAM, which is cheap in Desktop computers. Will we have problems with the WIFI cards in the desktops or any other unexpected hardware limitation? What tools should be used to "image" the servers. For example, when we get an installation right for a Redis server or Cassandra node, are there tools that come with Linux Centos 6.3 to image the server to a USB drive or something like that? Or do we need to use some other software for this? What other things are we missing that we should be concerned about? Thanks so much!

  • How to disable file download popup in Internet Explorer?

    - by Željko Filipin
    Hi, I was able to disable file download popup in all popular browsers except Internet Explorer. I thought this would do it, but I still get the popup: Internet Explorer Tools Internet Options Security select zone (example: Internet) Security levels for this zone Custom level... Downloads File download Automatic prompting for file downloads Disable OK Yes OK. I am not interested in automating the popup, I do not want it to appear. OS is Windows 2003, Internet Explorer 8.

  • Desktop.ini Issues/Confusion

    - by EpicDavi
    BACKSTORY: I was out of town for a while and I forgot to turn my computer off. When I came back I saw that a desktop.ini file was on my desktop (using Windows 7). I thought that was odd because I knew it was a system file and it usually didn't show up due to the fact that I had disable the feature to show system files. Also it wasn't translucent like the other system files. I went to my control panel and saw that the "Hide protected operating system files" was indeed enabled. This puzzled me so I disabled the setting and another one was on my desktop like it usually is hidden. So now I have to desktop.ini files on my desktop: one hidden and one not hidden. I am doing an antivirus check to see if anything was going on and I will give an update soon. I am pretty sure these files are harmless and could be deleted but I would rather get another person's opinion on the subject. Thanks! UPDATE: I did an anti-virus scan and it seems I have no problems. It is odd because the file seems to maintain system file properties such as not being able to be edited and other things. Also I have tried restarting my computer and it is still not hidden. So the question remains: What should I do with the file and what caused it?

  • IE9 will not navigate to some websites but Google Chrome can

    - by Storchburp
    Was recommended by a friend to ask for help here. I am using Internet Explorer 9. As of two days ago I was suddenly unable to navigate to any part of the following websites: www.computerandvideogames.com www.deviantart.com www.cnet.com However I can still access all of them normally through Google Chrome. I am on a college network but these sites are also accessible through fixed terminals provided by the school and are definitely not blocked. I do not know of any other sites similarly affected. There is no popup, no error message, no diversion to a site telling me I can't access / am blocked etc. I can be on www.google.com and attempt to access these sites through the URL or google search, and my cursor will just show the little moving blue wheel next to the arrow for a couple of seconds, and the page displayed on my browser will not change; ie. not navigating at all. Running antivirus software, changing proxy settings in IE, clearing cookies, unplugging/plugging in computer, restarting PC etc have not changed the situation. Any assistance or advice would be greatly appreciated. Thanks in advance.

  • Looking for speech-to-text tool (convert .wav to text)

    - by David
    I have the ability to get .wav files of voice mails emailed to me, but sometimes I'll be sitting in a meeting and I need to know the content of a message without playing it out loud. Are there any good (and, preferably, free) tools for converting .wav files to text? I know Google Voice has this capability, but I can't determine if it'll work on a file-by-file basis. I realize that this is a difficult research problem, but even an 80% solution might be workable.

  • Diagnosing and debugging LAN congestion / connection issues

    - by John Weldon
    What are the top N tools / methodologies used to diagnose and repair network issues? Given a LAN, for example, where users are able to consistently ping an outside server, but any data intensive connections are flaky; how would you begin solving the network issues? I imagine issues like congestion, bandwidth constraints, throughput constraints, etc. are all factors, but I don't know how to diagnose those issues. I'm especially interested in LAN environments (rather than WAN)

  • How to import UTM coordinates into Google Earth?

    - by Florian Jenn
    I have some points in UTM coordinates that I'd like to import into Google Earth. Google Earth is able to show UTM coordinates, but I have not found a way to import points or enter coordinates in a placemark's properties with UTM coordinates. Is there any possibility to do this with just Google Earth or do I need to convert my data set externally? I do have separate tools for coordinate conversion, but I'd like to spare the extra step.

  • Unable to access stackexchange sites from this system

    - by Sandeepan Nath
    Earlier, I was not able to access most of the stackexchange sites like stackoverflow, programmers.SE etc. on my home Windows XP system. I was able to access only a few like http://meta.stackexchange.com and not even http://www.meta.stackexchange.com (note the www). I tried many other sites like http://www.stackoverflow.com, http://area51.stackexchange.com/ but was getting page not found errors on all browsers. Even pinging from terminal was saying destination host unreachable. I did not check recently but may be all SE sites are unreachable now. I was clueless about what could be the issue. I thought some firewall issue? So, I stopped AVG antivirus's firewall, then completely uninstalled it and even turned of windows firewall. But still not reachable even after fresh installation of Windows 7. Then I noticed a "Too many requests" notice on google. This page - http://www.google.co.in/sorry/?continue=http://www.google.co.in/# I don't know why this appeared but I guess somehow too many requests might have been sent to these sites and they blocked me. But in that case, SE would be smart enough to show a captcha like google. So, how to confirm the problem and fix it. Similar questions like these don't look solved yet - Unable to access certain websites Unable to Access Certain Websites I have lately started actively participating in lots of SE sites. There are new new questions popping up in my mind every time and I am not able to ask them. Please help! Thanks

  • Microsoft Security Essentials & MsMpEng.exe hogging resources

    - by Mike
    I've been using MSE for a couple months now, never had a single problem. All of a sudden the process "MsMpEng.exe" will randomly go crazy and hog all my system resources so I can't do anything unless I kill it in the task manager. (I've quit the program for now and my comp is running smooth). When I restart the program, reboot, whatever, it goes off and hogs all the resources again after a couple minutes. If I kill the process it will go away and then come back a couple minutes later and do the same thing. I've scanned with MSE, another antivirus and malware with no probs. Any ideas? Should I uninstall and find something else? The thing is I've liked it so far. I'm running Win7 64-bit. Also, I'm not running any other conflicting security programs. This is the only one on my PC right now. Windows Defender is also off.

  • Load Testing a Security/Gateway Appliance

    - by Joel Coel
    In a couple weeks I will load testing a security/gateway appliance. We're a small residential college, and that "residential" means the traffic moving through the appliance is a bit like the Wild West. We have everything from Facebook to World of Warcraft, BitTorrent to Netflix, or Halo to YouTube... basically anything you might find in the home of a high-school or college aged person. Somewhere in there some real academic work gets done as well. We rely on our current appliance for traffic shaping, antivirus, malware filtering, intrusion detection on our servers, logging and abuse reporting, and even some content filtering. All this puts a decent load when we have students around, and I'm concerned about the ability of the new candidate to keep up. On paper it should handle things, but I'm worried. Prior experience is that vendors greatly over-report what an appliance can handle. The product also includes a licensed session limit, and I'm also worried that just a few misbehaving students could unwittingly bring us to that limit and cause service disruptions. I need to know this will work for our campus in order to commit to it. Going a performance level higher in that product takes the pricing way out of line with what we expect and have done in the past. What I need is a good way to load test this guy. My problem is that our current level of summer traffic is less than one percent of what it will be when students come back just six weeks from now. Any ideas on how to really stress this thing and see what it can do, in a way that will give me some clear ideas o. How that will scale for our campus? For the curious, I'm looking at a Watchguard 515, but it could be anything. If I were evaluating a competitor, I'd ask the same question.

  • What is the best error monitoring tool for Ruby on Rails applications?

    - by marcgg
    I'm looking for something to track the errors being raised across our multiple rails applications on our multiple servers. Ideally: the application failings sends an email to [email protected] and the email is processed in another application. This application will then show us some stats and give us some kinds of auditing tools. A service like Hoptoad might do the trick, but I'm trying to see what's available these days. Ideally free or cheap, of course...

  • Nagios graphing solutions vs Munin/Cacti/Ganglia

    - by sumek
    I've got a nagios server setup for monitoring ~ 30 Windows servers. I want to add some trending charts. I've read that nagios graphing plugins are simple and many people use seperate, standalone charting/trending tools. What are the restrictions of the nagios graphing plugins vs standalone products like ganglia/munin/cacti? I'm interested in specific features and advantages that standalone packages offer and nagios graphing plugins don't.

  • Install compiled linux program on multiple computers

    - by jtnire
    I'm sorry if this sounds like a silly question, but when I compile something on linux using the usual "./configure, make, make install" steps, how can I install the programs on other servers without having to recompile? I am trying to avoid having to install the build tools on production servers, however I need the latest version of a particular piece of software, so using RPMs isn't an option in this case. Any help is appreciated. Thanks

  • Create a new Plesk CLI user

    - by mattdwen
    I am trying to create a user which has rights to the Panels (v11) CLI tools. I've added the user to the psaadm group, as the documentation indicates, as well as the swkey-data group, as I was getting access denied for that dir. I am using sudo to run the command as that user: sudo -u mcp /usr/local/psa/bin/subscription --info test.com But I am receiving this error: Unable to connect to database: get_admin_password() failed: file_get_contents() failed: Suggestions?

  • How to find hidden/cloak files in Windows 2003?

    - by homemdelata
    Here is the point. I set Windows to display all the hidden files and protected operating system files but even after that, my antivirus (Kaspersky) is still getting a ".dll" file on "c:\windows\system32" saying it's a riskware 'Hidden.Object'. I tried to find this file everytime but it's not there. So I asked one of the developers to create a service that verifies the folder each 5 seconds and, if it founds the file, copies to another place. If it copies to another place with the same name and extension, I still can't find the file on the other folder but Kaspersky now founds both. If I keep the same name but with a different extension, like ".temp123", I still can't find the file. Lastly, I created an empty text file and renamed with the same name as the other one, the file just gone too. After all this research It's clear that every file with this same name on this specific server gets cloak, doesn't matter the file extension. I created a file with this same name on another server and nothing happens, the file is still there without problem. How can I found this kind of file? How can I "uncloak" it? How can I know what this file is doing?

  • How do I remove the on screen keyboard from the logon screen in Windows Remote Desktop Server 2008 R

    - by Gomibushi
    The on screen keyboard (OSK) from the "ease of access" tools pops up on EVERY connect to the server, even if you have not activated it. I can't seem to find a control panel or reg setting to switch it off. It is VERY "in your face" for linux users who connect at lower resolutions and do not provide all credentials, but have to type username and password. I'm running a 2008 R2 Terminal Server/Remote Desktop Server.

  • Mac Security - Which one?

    - by Bob Rivers
    Hi, Recently I had my credit card cloned. A few hours after shopping at an online store (in which I trust and buy since 2006) I received a call from my bank asking if I recognize a $5,000 debt to a store(?!) called Church of Christ... I'm a Mac user (OS X 10.6.3). I always kept my system updated and I have firewall enabled (in my Mac and in my broadband router), but I decided to adopt some kind of protection. I don't want to rise passionate discussions. Real or not, snake oil or not, I need to have back my peace of mind... I read this and this posts. I selected two software that I think that could help me (both have more features other than just an antivirus). Does someone have feedback about Intego's VirusBarrier X6 or Trendmicro's Smart Surfing? Intego solutions seems to be better, but TrendMicro brand/name is stronger in corporate environment, so their solution should be good. Both solutions have 30 day free trial, but I would like to hear something from you. Any other solution that I should look? TIA, Bob
