• Server Recovery from Denial of Service

  - by JMC

  I'm looking at a server that might be misconfigured to handle Denial of Service. The database was knocked offline after the attack, and was unable to restart itself after it failed to restart when the attack subsided. Details of the Attack: The Attacker either intentionally or unintentionally sent 1000's of search queries using the applications search query url within a couple of seconds. It looks like the server was overwhelmed and it caused the database to log this message: Server Specs: 1.5GB of dedicated memory Are there any obvious mis-configurations here that I'm missing? **mysql.log** 121118 20:28:54 mysqld_safe Number of processes running now: 0 121118 20:28:54 mysqld_safe mysqld restarted 121118 20:28:55 [Warning] option 'slow_query_log': boolean value '/var/log/mysqld.slow.log' wasn't recognized.

• Wifi antenna extension with F-connector/RG-6(RG-59) cable?

  - by rjz2000

  In an older house, the wire mesh in walls surrounding the furnace behave like a Faraday cage and block wifi signals. It is also difficult to lay new cable, however there is television cable to multiple locations due to there once having been a roof-installed, television antenna. It would be relatively trivial to install the wifi router at the center distribution point, then have the antenna broadcasting/receiving the signal plugged in at each of the old television outlets. I assume that it would not be too difficult to find an adapter for SMA <- F-type connectors. The cable is actually RG-59 rather than RG-6, but I assume that it still has relatively good RF isolation along its length, which is no more than a couple hundred feet in any direction. Does anyone know a problem with the idea? Will a router get confused if there is /too little/ interference between the two antenna? Is that length of cable (~100ft) too long for the signal a router broadcasts? I have seen that it is also possible to use old ~$30/each FiOS cable modems available on eBay to extend a network over television cable. However, that seems like a less elegant solution, and might interfere with upnp and dlna services I'd like to have work on a single network. Thanks if anyone has answers or suggestions before I try this project!

• MacBook Pro (2007 - ATI-Card) Screen goes half black then shuts down the entire computer

  - by BluePerry

  Hey, when I'm starting my MBP I get about 10-60 seconds of the booting process before the screen goes half black (Its like applying a black to transparent gradient from the left side of the screen to the middle of the screen). After a 5 seconds the entire screen blacks out and the MBP shuts down. There have been issues with heat and some minor artifacts on the screen in the past but nothing serious as far as I know. Everything could be resolved by rebooting or letting the MBP cool down a bit. I would like to identify the problem now. There are 3 possibilities I can think of right now: My graphics card is defect and shuts down after a few seconds. (But if thats true, I find it kind of hard to explain the HALF black screen) My LCD-Panel is defect and sends back wrong signals so the system shuts down??? (I not sure about that) My fan or/and thermal sensors are defect and forcing the graphics card to shut down. Can anyone point if I'm right or if there yet another reason for this. I'd be thankful for any hint or tips. Cheers, Per

• Linux: CIFS/Samba mount hangs for several minutes

  - by Pistos

  I have a small local network which has a Gentoo box and a Windows box. I mount a share originating on the Windows box onto the Gentoo box with a command like: mount -t cifs -o username=WindowsUsername,password=thepassword,uid=pistos //192.168.0.103/Users /mnt/windowsbox Most of the time, everything Just Works, and I can read and write without problems. However, every few weeks or so, the connection or the mount point seems to go dead or hang, such that any process that tries to access the mount point gets stuck in D state (disk, or I/O wait). These processes become impervious to TERM and KILL signals. Disconnecting and reconnecting the Windows box from the network does not help. The frozen state lasts for 5+ minutes. It's really frustrating and gets in the way of normal work, because it freezes Save As dialogues, ls commands, etc. If I issue a umount on the mount point, it either hangs also, or reports that the mount point is in use. Eventually, the dead state resolves itself, and the mount point gets unmounted, or it becomes possible to umount with no delay. My guess is that this happens when the connection/mount has gone idle, or when the Windows machine has been idle. I am not really sure. Why is this happening, and what can I do to prevent it? Or how can I successfully kill these D-state processes at will? Possibly related: CIFS mounts hang on read

• What user information is exposed via a browser?

  - by ipso

  Is there a function or website that can collect and display ALL of the user information that can be obtained via a browser? Background: This of course does not account for the significant cross-reference abilities of large corporations to collate multiple sources and signals from users across various properties, but it's a first step. Ghostery is just a great idea; to show people all of the surreptitious scripts that run on any given website. But what information is available – what is the total set of values stored – that those scripts can collect from? If you login to a search engine and stay logged in but leave their tab, is that company still collecting your webpage viewing and activity from other tabs? Can past or future inputs to pages be captured – say comments on another website? What types of activities are stored as variables in the browser app that can be collected? This is surely a highly complex question, given to countless user scenarios – but my whole point is to be able to cut through all that – and just show the total set of data available at any given point in time. Then you can A/B test and see what is available with in a fresh session with one tab open vs. the same webpage but with 12 tabs open, and a full day of history to boot. (Latest Firefox & Chrome – on Win7, Win8 or Mint13 – although I'd like to think that won't make too much of a difference. Make assumptions. Simple is better.)

• What differences are there between "home" switches and "professional" switches?

  - by pjreddie

  Our radio station uses a PtP wireless system to stream our radio and TV signals from our studio up a hill to our transmitter. We have been having problems with warbly sound and drop outs that come from some point in this system. An engineer that occasionally visits the station thinks it could be the switches we use on each side of the PtP wireless system to connect the PtP devices to the encoders and decoders and wants us to get two of these switches: http://www.amazon.com/Netgear-JGS516-ProSafe-16-Port-Ethernet/dp/B0002CWPOK/ref=dp_return_1 The encoder/decoder setup only streams 8Mbps total so it seems like the switches we have should not be stressed out, unless they are causing sufficient latency to degrade the performance of the encoder/decoder. At each end of the connection we only have 4 connections, is there any reason we couldn't get a cheaper, "home" quality switch like this: http://www.amazon.com/D-Link-DGS-1005G-5-Port-Gigabit-Desktop/dp/tech-data/B003X7TRWE/ref=de_a_smtd Is there a significant difference that we would notice in terms of latency between these two switches? How much does the quality of the switch actually matter in this scenario? Any help is appreciated, feel free to ask questions if anything needs clarification. Thanks

• Configuring two nearby WLANs: should I use the same ssid?

  - by Rory

  I'm configuring a home network for basic internet use (ie don't really need connectivity between workstations on the network). My brick walls mean a single wireless router doesn't provide good coverage throughout the house, so I have purchased two powerline adapters and now have the incoming modem/wireless router at one end of the house plugged into a powerline adapter, and at the other end of the house the other powerline adapter plugged into another wireless router. Currently the two wireless networks have different ssids. (The powerline adapters only do power-Ethernet; they're not wireless access points themselves.) This works well, except when I move between rooms and would ideally like my devices (iPad, phones, laptops) to switch from the weak to the strong signal. Sometimes there's enough signal that they hold on to the weak connects instead of switching to the strong one. Should I name the two networks the same ssid, and if so what is the actual effect? Do the signals get confused, is the bandwidth affected, will this help my devices seamlessly move from one to the other, or is the ssid just a cosmetic thing that actually doesn't have any impact on this situation? Are there any other settings that I should configure to make my setup optimal?

• A switch and router between the printer and PC that want to print but cannot

  - by Robert Memo

  IP 192.168.1.5 has a wireless connection to a Linksys router (192.168.1.1) which then is connected to a switch. The switch is connected to a server (192.168.0.2). My printer has IP address of 192.168.0.8. Internet connection is fine on 192.168.1.5. Problem 1: IP 192.168.1.5 can not print using printer 192.168.0.8. Problem 2: IP 192.168.1.2 can not access a shared folder on the the server. The reason for connecting this way is that, the server does not release wireless signal. In order to get wireless signal the Router is connected to the switch. The server is a computer server that only has one outgoing LAN port. Plus, due to inconvinience physical locations, I do not have option to change the physical locations and the way it is connected already. I just want the labtops that only have wireless connection to communicate with the printer and the server. I have tried to change the router IP address to 192.168.0.x like the server and printer. It caused problem for the laptop. The router no longer release internet signals. The router does have IP address from the server 192.168.0.5.

• Why just splitting an Ethernet cable does not work?

  - by Sin Jeong-hun

  I thought the Ethernet is logically one-line communication bus (for argument's sake, I am excluding hubs). All machines attached in the bus hears the same signals and the machines themselves try to avoid collisions by randomly backing off. http://computer.howstuffworks.com/ethernet6.htm If so, why splitting one Ethernet line from my home router into two and connecting two computers would not work? Why do I have to add a switch to it? *What the Internet said would not work. [4 port home router] ------[one Ethernet cable]-----[simple splitter]======[two computers] *What the Internet said I should do [4 port home router] ------[one Ethernet cable]-----[switch]======[two computers] Is this because of the signal degradation (reduced electric current)? Thank you for all the answers! The reason why I did not just use the two ports of my home router is... The 4-port gigabit router is in my room and I had put a computer in another room (also my room, though). Since wired network is far more reliable and secure, I had bought a long Ethernet cable and and connected the computer to the router. Now I was thinking about adding another computer to that room. I could buy another long Ethernet cable, but then there will be two cables between the rooms. The one line already is a minor annoyance, so I thought if I could share the one line between the two computers in that room. A switch would work, but it requires power and is a little bit pricey. That is why I wondered why it would not work to simply split the physical Ethernet cable. Apparently I do not completely understand how Ethernet and a switch work. I just have some bit of knowledge I heard in my college class.

• External HDD connecting via USB disconnects wireless LAN connection

  - by Kensai

  Strange problem. I have this MEDION Akoya PC that has a dedicated bay to slide an external HDD sold separately. It's very handy indeed cause the slot is providing a fast USB 3 connection and power to the HDD unit, without extra cables. All works fine except this show-stopper behavior to disconnect me from the router once I slide in the unit and it powers up. The moment I connect the unit the (normally) three-four WiFi connections I see in my neighborhood disappear and my own to the router loses its signal strength (no Internet traffic is possible). After a while it throws me off that one as well, never to connect me again as long as the unit is powered. Once I disconnect the HDD the various signals come back and it automatically reconnects to my own. What takes? Are we in front of a serious design fault by MEDION here? Does the spinning of the HDD on top of the PC cause electromagnetic interference strong enough to throw off my WiFi connectivity? Is it a simple USB problem? Some kind of strange hardware conflict? Where should I look?

  I activated following code with feature (web level scope). Now when i add an item to any document library it should create a folder "". No folder is created and no error is given either. can anyone see what's is going on? I got the following from the log file. I found similar code all over google so I am kinda puzzled why is not working in my environment. Thanks using System; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint; namespace AddaFolder { class clAddaFolder : SPItemEventReceiver { public override void

• BizTalk server problem

  - by WtFudgE

  Hi, we have a biztalk server (a virtual one (1!)...) at our company, and an sql server where the data is being kept. Now we have a lot of data traffic. I'm talking about hundred of thousands. So I'm actually not even sure if one server is pretty safe, but our company is not that easy to convince. Now recently we have a lot of problems. Allow me to situate in detail, so I'm not missing anything: Our server has 5 applications: One with 3 orchestrations, 12 send ports, 16 receive locations. One with 4 orchestrations, 32 send ports, 20 receive locations. One with 4 orchestrations, 24 send ports, 20 receive locations. One with 47 (yes 47) orchestrations, 37 send ports, 6 receive locations. One with common application with a couple of resources. Our problems have occured since we deployed the applications with the 47 orchestrations. A lot of these orchestrations use assign shapes which use c# code to do the mapping. This is because we use HL7 extensions and this is kind of special, so by using c# code & xpath it was a lot easier to do the mapping because a lot of these schema's look alike. The c# reads in XmlNodes received through xpath, and returns XmlNode which are then assigned again to biztalk messages. I'm not sure if this could be the cause, but I thought I'd mention it. The send and receive ports have a lot of different types: File, MQSeries, SQL, MLLP, FTP. Each of these types have a different host instances, to balance out the load. Our orchestrations use the BiztalkApplication host. On this server also a couple of scripts are running, mostly ftp upload scripts & also a zipper script, which zips files every half an hour in a daily zip and deletes the zip files after a month. We use this zipscript on our backup files (we backup a lot, backups are also on our server), we did this because the server had problems with sending files to a location where there were a lot (A LOT) of files, so after the files were reduced to zips it went better. Now the problems we are having recently are mainly two major problems: Our most important problem is the following. We kept a receive location with a lot of messages on a queue for testing. After we start this receive location which uses the 47 orchestrations, the running service instances start to sky rock. Ok, this is pretty normal. Let's say about 10000, and then we stop the receive location to see how biztalk handles these 10000 instances. Normally they would go down pretty fast, and it does sometimes, but after a while it starts to "throttle", meaning they just stop being processed and the service instances stay at the same number, for example in 30 seconds it goes down from 10000 to 4000 and then it stays at 4000 and it lowers very very very slowly, like 30 in 5minutes or something. So this means, that all the other service instances of the other applications are also stuck in here, and they are also not processed. We noticed that after restarting our host instances the instance number went down fast again. So we tried to selectively restart different host instances to locate the problem. We noticed that eventually restarting the file send/receive host instance would do the trick. So we thought file sends would be the problem. Concidering that we make a lot of backups. So we replaced the file type backups with mqseries backups. The same problem occured, and funny thing, restarting the file send/receive host still fixes the problem. No errors can be found in the event viewer either. A second problem we're having is. That sometimes at arround 6 am, all or a part of the host instances are being stopped. In the event viewer we noticed the following errors (these are more than one): The receive location "MdnBericht SQL" with URL "SQL://ZNACDBPEG/mdnd0001/" is shutting down. Details:"The error threshold has been exceeded. The receive location is shutting down.". The Messaging Engine failed to add a receive location "M2m Othello Export Start Bestand" with URL "\m2mservices\Othello_import$\DataFilter Start*.xml" to the adapter "FILE". Reason: "The FILE adapter cannot access the folder \m2mservices\Othello_import$\DataFilter Start. Verify this folder exists. Error: Logon failure: unknown user name or bad password. ". The FILE adapter cannot access the folder \m2mservices\Othello_import$\DataFilter Start. Verify this folder exists. Error: Logon failure: unknown user name or bad password. An attempt to connect to "BizTalkMsgBoxDb" SQL Server database on server "ZNACDBBTS" failed. Error: "Login failed for user ''. The user is not associated with a trusted SQL Server connection." It woould seem that there's a login failure at this time and that because of it other services are also experiencing problems, and eventually they are shut down. The thing is, our user is admin, and it's impossible that it's password is wrong "sometimes". We have concidering that the problem could be due to an infrastructure problem, but that's not really are department. I know it's a long post, but we're not sure anymore what to do. Would adding another server and balancing the load solve our problems? Is there a way to meassure our balance and know where to start splitting? What are normal numbers of load etc? I appreciate any answers because these issues are getting worse and we're also on a deadline. Thanks a lot for replies!

• Remote EJB lookup issue with WebSphere 6.1

  - by marc dauncey

  I've seen this question asked before, but I've tried various solutions proposed, to no avail. Essentially, I have two EJB enterprise applications, that need to communicate with one another. The first is a web application, the second is a search server - they are located on different development servers, not in the same node, cell, or JVM, although they are on the same physical box. I'm doing the JNDI lookup via IIOP, and the URL I am using is as follows: iiop://searchserver:2819 In my hosts file, I've set searchserver to 127.0.0.1. The ports for my search server are bound to this hostname too. However, when the web app (that uses Spring btw) attempts to lookup the search EJB, it fails with the following error. This is driving me nuts, surely this kind of comms between the servers should be fairly simple to get working. I've checked the ports and they are correct. I note that the exception says the initial context is H00723Node03Cell/nodes/H00723Node03/servers/server1, name: ejb/com/hmv/dataaccess/ejb/hmvsearch/HMVSearchHome. This is the web apps server NOT the search server. Is this correct? How can I get Spring to use the right context?

• Instruments memory leak iphone

  - by dubbeat

  Hi, I posted this problem a few days ago but it was very muddled and my question wasnt very clear so I removed it. I've been digging around and the memory leak is still persiting. Hopefully this attempt will be clearer. First off I've run the static analyzer and it reports no memory leaks. I then ran Instruments and it pointed to a memory leak at this line of code. As far as I can see there is no memory leak. featured=[[UILabel alloc]initWithFrame:CGRectMake(130,15, 200, 15)]; //[featured setFont:[UIFont UIFontboldSystemFontOfSize:20]]; featured.font = [UIFont boldSystemFontOfSize:20]; featured.backgroundColor= [UIColor clearColor]; featured.textColor=[UIColor blackColor]; featured.text= @"Featured Promo"; [self.view addSubview:featured]; [featured release]; featured=nil; If I comment out the above code Instruments reports another memory leak in another block of code where there is no discernible leak. UIButton *populartbutton = [[UIButton buttonWithType:UIButtonTypeRoundedRect]]; populartbutton.frame = CGRectMake(112, 145, 90, 22); // size and position of button [populartbutton setTitle:@"Popular" forState:UIControlStateNormal]; populartbutton.backgroundColor = [UIColor clearColor]; populartbutton.adjustsImageWhenHighlighted = YES; [populartbutton addTarget:self action:@selector(getpopular:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:populartbutton]; Instruments also says Responsible Library = Core Graphics Responsible Frame = open_handle_to_dylib_path This Is the stack trace. 53 Promo start 52 Promo main /Users/..2/main.m:14 51 UIKit UIApplicationMain 50 UIKit -[UIApplication _run] 49 CoreFoundation CFRunLoopRunInMode 48 CoreFoundation CFRunLoopRunSpecific 47 GraphicsServices PurpleEventCallback 46 UIKit _UIApplicationHandleEvent 45 UIKit -[UIApplication sendEvent:] 44 UIKit -[UIApplication handleEvent:withNewEvent:] 43 UIKit -[UIApplication _reportAppLaunchFinished] 42 QuartzCore CA::Transaction::commit() 41 QuartzCore CA::Context::commit_transaction(CA::Transaction*) 40 QuartzCore CALayerLayoutIfNeeded 39 QuartzCore -[CALayer layoutSublayers] 38 UIKit -[UILayoutContainerView layoutSubviews] 37 UIKit -[UINavigationController _startDeferredTransitionIfNeeded] 36 UIKit -[UINavigationController _startTransition:fromViewController:toViewController:] 35 UIKit -[UINavigationController _layoutViewController:] 34 UIKit -[UINavigationController_computeAndApplyScrollContentInsetDeltaForViewController:] 33 UIKit -[UIViewController contentScrollView] 32 UIKit -[UIViewController view] 31 Promo -[FeaturedLevelViewController viewDidLoad] /Users/..s/FeaturedLevelViewController.m:67 // THIS IS MY CLASS WHERE THE CODE SAMPLES ABOVE ARE FROM 30 UIKit -[UILabel initWithFrame:] 29 UIKit -[UILabel _commonInit] 28 UIKit +[UILabel defaultFont] 27 UIKit +[UIFont systemFontOfSize:] 26 GraphicsServices GSFontCreateWithName 25 CoreGraphics CGFontCreateWithName 24 CoreGraphics CGFontCreateWithFontName 23 CoreGraphics CGFontFinderGetDefault 22 CoreGraphics CGFontGetVTable 21 libSystem.B.dylib pthread_once 20 CoreGraphics load_vtable 19 CoreGraphics load_library 18 CoreGraphics CGLibraryLoadFunction 17 CoreGraphics load_function 16 CoreGraphics open_handle_to_dylib_path 15 libSystem.B.dylib dlopen 14 dyld dlopen 13 dyld dyld::link(ImageLoader*, bool, ImageLoader::RPathChain const&) 12 dyld ImageLoader::link(ImageLoader::LinkContext const&, bool, bool, ImageLoader::RPathChain const&) 11 dyld ImageLoader::recursiveLoadLibraries(ImageLoader::LinkContext const&, bool, ImageLoader::RPathChain const&) 10 dyld dyld::libraryLocator(char const*, bool, char const*, ImageLoader::RPathChain const*) 9 dyld dyld::load(char const*, dyld::LoadContext const&) 8 dyld dyld::loadPhase0(char const*, dyld::LoadContext const&, std::vector<char const*, std::allocator<char const*> >*) 7 dyld dyld::loadPhase1(char const*, dyld::LoadContext const&, std::vector<char const*, std::allocator<char const*> >*) 6 dyld dyld::loadPhase3(char const*, dyld::LoadContext const&, std::vector<char const*, std::allocator<char const*> >*) 5 dyld dyld::loadPhase4(char const*, dyld::LoadContext const&, std::vector<char const*, std::allocator<char const*> >*) 4 dyld dyld::loadPhase5(char const*, dyld::LoadContext const&, std::vector<char const*, std::allocator<char const*> >*) 3 dyld dyld::mkstringf(char const*, ...) 2 dyld strdup 1 dyld malloc 0 libSystem.B.dylib malloc I'm really not too sure how to use this information to fix the problem so any guidance would be appreciated.

• Search and display buisness locations on MKMapView

  - by jmurphy

  Hello, I'm trying to find a way to search for a business, such as "grocery stores" and display them on a google map around the users current location. This used to be pretty simple with the old URL style of launching the apple map location but I can't find out how to do it with the MKMapView. I understand that I'll need to use the MKAnnotations classes but my problem is with finding the data. I've tried plugging in the URL below to get the info from google but the size of the data seems way too large. http://maps.google.com/maps?q=grocery&mrt=yp&sll=37.769561,-122.412844&z=14&output=kml Is there an easy way to just set a property that tells the MKMapView to search for a keyword and display all matching business around my current location? Or does anybody know how to get this information from google?

• Getting Rails Application Running Under IronRuby Rack

  - by NotMyself

  Anyone else playing with ironruby? I have successfully got the IronRuby.Rails.Example project running on my local machine under IIS 5.1. I am now attempting to get my own demo rails site running in the same way. My web.config is slightly different from the example project. I am attempting to only use what was distributed with IronRuby 1.0 and what I have installed using gems. I am getting the following error which doesn't give me a lot to go on: D:/demo/config/boot.rb:66:in `exit': exit (SystemExit) After trying many different things, I think it is having a problem finding gems. I have attached my web config and ironrack.log. Does anyone have pointers on what I am doing wrong?
