• Why does my MySQL remote-connection fail (VLAN)?

  - by Johannes Nielsen

  ubuntu-community! Again I have a problem with my special friend MySQL :D I have got two servers - a database-server and a web-server - who are connected via VLAN. Now I want the web-server to have remote access to the database-server's MySQL. So I created the user user in mysql.user. user's Host is xxx.yyy.zzz.9 which is the internal IP-address of the web-server. xxx.yyy.zzz.0 is the network. I also created user with Host % . As long as I use MySQL on the database-server logging in as user, everything works fine. But trying to log in as user from xxx.yyy.zzz.9 using mysql -h xxx.yyy.zzz.8 -u user -p (where xxx.yyy.zzz.8 is the database-server's internal IP), I get ERROR 2003 (HY000): Can't connect to MySQL server on 'xxx.yyy.zzz.8' (110) So I tried to activate Bind-Address in the my.cnf file. Well, if I use xxx.yyy.zzz.8, nothing changes. But if I try xxx.yyy.zzz.9 and try to restart MySQL, I get mysql stop/waiting start: Job failed to start I checked the log files and found - nothing. The database-server's MySQL doesn't even register, that the web-server tries to connect remotely. My idea is, that maybe I didn't configure the VLAN properley, even though I asked someone who actually knows such stuff and he told me, I did everything right. What I wrote into /etc/networking/interfaces is: #The VLAN auto eth1 iface eth1 inet static address xxx.yyy.zzz..8 netmask 255.255.255.0 network xxx.yyy.zzz.0 broadcast xxx.yyy.zzz.255 mtu 1500 ifconfig returns eth1 Link encap:Ethernet HWaddr xxxxxxxxxxxxxx inet addr:xxx.yyy.zzz.8 Bcast:xxx.yyy.zzz.255 Mask:255.255.255.0 inet6 addr: xxxxxxxxxxxxxxx/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:241146 errors:0 dropped:0 overruns:0 frame:0 TX packets:9765 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17825995 (17.8 MB) TX bytes:566602 (566.6 KB) Memory:fb900000-fb920000 for the eth1, what is, what I configured. (This is for the database-server, the web-server looks similar). ethtool eth1 returns: Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000003 (3) drv probe Link detected: yes (This is for the database-server, the web-server looks similar). Actually I think, everything is right, but it still doesn't work. Is there someone with an idea? EDIT: I commented ou Bind-Address in my.cnf after it didn't work.

• netsh wlan add profile not importing encrypted passphrase

  - by sirlancelot

  I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings or am I missing something about adding profiles? Here is the exported xml with personal information removed: <?xml version="1.0"?> <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1"> <name>[removed]</name> <SSIDConfig> <SSID> <hex>[removed]</hex> <name>[removed]</name> </SSID> <nonBroadcast>false</nonBroadcast> </SSIDConfig> <connectionType>ESS</connectionType> <connectionMode>auto</connectionMode> <autoSwitch>false</autoSwitch> <MSM> <security> <authEncryption> <authentication>WPAPSK</authentication> <encryption>TKIP</encryption> <useOneX>false</useOneX> </authEncryption> <sharedKey> <keyType>passPhrase</keyType> <protected>true</protected> <keyMaterial>[removed]</keyMaterial> </sharedKey> </security> </MSM> </WLANProfile> Any help or advice is appreciated. Thanks. Update: It seems if I export the settings using key=clear, the passphrase is stored in the file unprotected and I can import the file on another computer without issue. I've updated my question to reflect my findings.

• Issues getting a Cisco WLC 5508 to find AIR-LAP1142N

  - by user95917

  hoping someone can help me with a problem here. I'm attempting to setup a test (loan from Cisco) wireless network. Here's what i've got/done: 5508 Controller - Service Port IP set to 10.74.5.2 /24. Management IP set to 10.74.6.2 /24 with a default gateway of 10.74.6.1. Virtual IP set to 1.1.1.1. Copper SFP in slot 7, CAT5 (known good) going from there to port 1/0/47 on the switch. Green lights on both ends. 2960-S Switch - Vlan1 - 10.74.6.1 /24. dhcp pool 10.74.6.0 /24, default router 10.74.6.1. excluded-address 10.74.6.1, 10.74.6.2. 1/0/4 on the switch is set to switchport mode access and no shut. 1/0/47 on the switch is setup to switchport mode trunk and no shut. 1/0/4 has a CAT5 (known good) cable going from there to the AP. When I do a sh cdp nei from the switch, i can see the AP and Controller listed. When i configure my PC's nic to 10.74.5.5, and plug a cable from my nic to the SP port on the controller i can get on the device via the gui. In there, the only errors/info that show up in the trap are: Link Up: Slot: 0 Port: 7 Controller time base status - Controller is out of sync with the central timebase. I've manually set the time but apparently that's not quite the problem (or at least not the entire problem). When i plug the AP in, i see on the switch console that it grants it power, it sees it connect...but the controller won't see it for some reason. From what i've read you shouldn't have to do anything to the AP as it's managed by the controller...but i'm not sure what setting I'm missing for it to work. The AP light on top is continually cycling green, red, yellow. When I first start it up, it blinks green for 20 or so seconds, then goes to solid green for another 20 seconds or so, then flashes blue, green, red for awhile...but always ends up goinn back to the standard, green, red, yellow. Does anyone see any obvious issues with my setup or have any suggestions as to why i might be having a problem? Thanks for your help!

• Can't ping devices by IP address for devices allocated IPs by DHCP

  - by GiddyUpHorsey

  I have a home network with a Trendnet wireless router and a Windows Domain. The Domain Controller/DNS server is a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. The network has been set up for a couple of years and usually works fine. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. The router UI shows that the laptop has a reserved IP allocated via DHCP. All machines either have a static or DHCP allocated IP on the 192.168.0.* subnet. Router - 192.168.0.1 - Static - Wired Windows Domain Controller - 192.168.0.8 - Static - Virtual Windows 7 Workstation - 192.168.0.200 - DHCP Auto - Wired VMWare ESXi Host - 192.168.0.201 - Static? - Wired iPhone 1 - 192.168.0.202 - DHCP Auto - WiFi iPhone 2 - 192.168.0.203 - DHCP Auto - WiFi Windows Vista Laptop - 192.168.0.204 - DHCP Reserved - WiFi Using the Windows 7 machine (200), I try to ping each machine and the only DHCP machine that responds is itself. The other DHCP machines fail with Reply from 192.168.0.200: Destination host unreachable.. Using nslookup fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the Windows 2000 Domain Controller (8), I try to ping each machine and the only DHCP machine that responds is the Windows 7 machine (200). Pinging the other DHCP machines fails with Request timed out.. Using nslookup also fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the iPhone 2 (203), I try to ping (Network Ping Lite) the machines with static IP addresses and that works fine. When I try to ping the Windows 7 machine (200) it is unable to get a response. How do I configure the DNS server/Windows Domain/Router properly so that the Windows Domain machines can see the IPs allocated via DHCP?

• How to make Windows 7 use the internet connection that I specify

  - by user138957

  I have a LAN adapter and a USB wireless internet connection. When both connected windows 7 always uses the USB. I tried changing the metric values but no luck. Let me explains the steps I took. Currently automatic metric on all adapters. LAN connected. ipconfig shows that it is connected to the correct ip/dns/gateway etc. IPv4 Route table shows Metric 24 Then connected USB. ipconfig shows USB connectivity then LAN in that order. Internet is now through USB. IPv4 Route table shows Metric 4249 for LAN and USB is 41. Gateway for USB shows "on-link". netstat -rn shows USBDEVICE on top. Changed LAN metric to 5 and now the route table shows LAN as 9 (not sure why it added 4) and USB as 41. netstat shows LAN then USB. ipconfig shows LAN then USB. But still connection is through USB. How do I know? Task manager shows utilization only through USB as well as speed is showing around 1mbps rather than LANs 10mbps. How can I get win7 use LAN while USB is connected. I am just trying to use USB as a backup just in case I lose LAN connection. Please help!! I thought i will make USB metric manually to say 10. But it says I have to reconnect for it to be effective. Currently USB still shows below LAN and still has 9 and 41 in the table. Disconnected USB. Table shows LAN metric as 24 (Not sure why it got changed from 9 and setting got reverted by to automatic) Reconnected USB. Now in the setting still shows 10 and the route table shows 11 for USB and LAN shows 4249 (settings shows 4245, 4 less)) For some reason restarting USB is resetting LAN setting when reconnected. Thanks

• Wifi randomly drops on Windows 8 laptop

  - by JosiahS

  First of all, I did a lot of research on this problem, and I wasn't able to come to any helpful conclusion. I've finally decided that I need advice from those who might know where to look. So don't let me down. :P I used to have an older Windows 7 laptop, which worked great for basic office and web browsing. However, I wanted something that would play actual modern games. So I recently bought a Sager NP8235 with the Intel Wireless-AC 7260 wifi card, and installed Windows 8 Pro on it. And ever since, I've been having problems with the wifi. Generally, what happens is if I leave the laptop on but inactive for an extended amount of time (I've estimated it around an hour to two), the wifi will start dropping randomly. If I happened to have a download going at the time, it usually causes the download to fail. Or, if I put the laptop to sleep overnight, the next morning I usually have to restart the computer because the wifi device apparently stops working (it literally won't turn on). Also, and most frustrating, whenever I'm on a video chat (like Skype), after about ten minutes, the connection will start lagging like crazy, until it forces Skype to end the call. After that, I usually have to disable and reenable the wifi to get it working again. I know it isn't our internet, because all the other computers in our house (~8) don't have any issues. Even the old Windows 7 laptop (connected also over wifi) works just fine, scoring the normal ~3Mbps average on speedtest.net (yes, I know our internet is slow, we live out in the country). Additionally, when I connect the Sager directly to the router via ethernet, the internet instantly starts working just great. Like I said, I've done a lot of googling to figure out what's going on, and I haven't been able to find anything that worked for me. Is it Windows 8 conflicting with the Wifi drivers? As of this writing, I have the Intel drivers v16.1.5.2 installed (without the extra Intel software). Or is it our router? It's a TP-Link TL-WR841ND, set to the default settings. The Sager is currently being assigned to a static IP, if that makes any difference. And yet, the old windows 7 laptop has a much more stable connection than the Sager. Anyone have any ideas? At this point, I'd appreciate even knowing what the problem is.

• Why does pinging a local router return "Destination Host Unreachable"?

  - by Matt H

  I have two tomato routers. One is bridged wirelessly with the other. I have a new server on the network. It's running Ubuntu Server 11.04. They are all connected like this: A - Linux PC B - New Server C - Mac Mini D - Macbook T1 - Tomato 1 T2 - Tomato 2 They are connected like so: A -----+-T1 ==== wireless bridge ==== T2----- ADSL modem | | C & D Connected wirelessly to T2 B -----+ A, C & D do not experience any issues. I have an active SSH session to B from A and it's not experiencing any loss. B, the new server occasionally cannot ping T2 and therefore cannot connect to the internet. However, A can always contact B and B can ping A and B When the network is lost, B can still ping T1, but not T2 yet at the same as B has lost connection to T2, A can still ping T2. Any ideas on what this could be? there is nothing that gives any clues in any of the logs on either router or the linux server. One thing that is interesting is that I set up a ping running between B and T2. T2 has the IP address 192.68.1.1 Here is what I am seeing: From 192.168.1.1 icmp_seq=26 Destination Host Unreachable From 192.168.1.1 icmp_seq=27 Destination Host Unreachable From 192.168.1.1 icmp_seq=28 Destination Host Unreachable From 192.168.1.1 icmp_seq=29 Destination Host Unreachable From 192.168.1.1 icmp_seq=30 Destination Host Unreachable From 192.168.1.1 icmp_seq=31 Destination Host Unreachable From 192.168.1.1 icmp_seq=33 Destination Host Unreachable From 192.168.1.1 icmp_seq=34 Destination Host Unreachable From 192.168.1.1 icmp_seq=35 Destination Host Unreachable 64 bytes from 192.168.1.1: icmp_req=36 ttl=63 time=3.40 ms 64 bytes from 192.168.1.1: icmp_req=37 ttl=63 time=5.70 ms 64 bytes from 192.168.1.1: icmp_req=38 ttl=63 time=2.25 ms 64 bytes from 192.168.1.1: icmp_req=39 ttl=63 time=2.18 ms 64 bytes from 192.168.1.1: icmp_req=40 ttl=63 time=3.12 ms 64 bytes from 192.168.1.1: icmp_req=41 ttl=63 time=2.15 ms 64 bytes from 192.168.1.1: icmp_req=42 ttl=63 time=1.97 ms 64 bytes from 192.168.1.1: icmp_req=43 ttl=63 time= And it cycles to being reachable and not. So I guess you could say the question is, why is the router responding that it cannot be reached?

• Trouble with setting entry point for GWT service

  - by Xorty

  Hello. I've followed serveral tutorials and read official docs at code.google.com, but still didn't manage to resolve this thing. I am creating simple service that'll check if user can be logged. CLIENT SIDE: public interface LoginService extends RemoteService { /** * Checks, if user has valid login. * @param user User's login. * @return True if such a login is in the database. */ boolean isValidUser(User user); } And here is Async interface: public interface LoginServiceAsync { /** * Checks, if user has valid login. * @param user User's login. * @param callback the callback to return True if such a login is in the database. */ void isValidUser(User user, AsyncCallback<Boolean> callback); } SERVER SIDE: public class LoginServiceImpl extends RemoteServiceServlet implements LoginService { /** * serial version UID */ private static final long serialVersionUID = 1044980345057997696L; /**{@inheritDoc} */ @Override public boolean isValidUser(User user) { boolean success = true; //TODO change } } Now I have entry point class MailClient.java. I append here widget like: CustomWidgets.getLoginWidget(this); // access rootPanel and append widget Now I need to make actual call to my service, and here is problem: LoginServiceAsync loginService = (LoginServiceAsync) GWT.create(LoginService.class); User user = new User(boxName.getText(), boxPassword.getText()); AsyncCallback<Boolean> callback = new AsyncCallback<Boolean>() { @Override public void onFailure(Throwable caught) { Window.alert(caught.getMessage()); //TODO change } @Override public void onSuccess(Boolean result) { Window.alert("success"); //TODO change } }; ((ServiceDefTarget) loginService).setServiceEntryPoint(GWT.getModuleBaseURL()+"login"); // dunno what should be here So to recap, I don't know how to set service's entry point. Here's my MailClient.gwt.xml file: <module> <inherits name="com.google.gwt.user.User"/> <inherits name="com.google.gwt.user.theme.standard.Standard"/> <entry-point class="com.xorty.mailclient.client.MailClient"/> <servlet path="/login" class="com.xorty.mailclient.server.servlets.LoginServiceImpl" /> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> <inherits name="com.xorty.mailclient.MailClient"/> </module> My web.xml file: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <!-- Default page to serve --> <welcome-file-list> <welcome-file>MailClient.html</welcome-file> </welcome-file-list> <servlet> <servlet-name>LoginService</servlet-name> <servlet-class>com.xorty.mailclient.server.servlets.LoginServiceImpl</servlet-class> </servlet> <servlet-mapping> <servlet-name>LoginService</servlet-name> <url-pattern>/com.xorty.mailclient.MailClient/login</url-pattern> </servlet-mapping> </web-app> And here is screenshot of project structure:

• Tomcat 6: Access Control Exception?

  - by iftrue

  I'm trying to setup a tomcat6 server, and I'm trying to match another setup someone else established. However, my deployment (default Ubuntu install) uses a policy.d/ directory structure, and the established server just uses a catalina.policy file. I've tried setting every entry in policy.d to match the given catalina.policy, but I still get the following stacktrace on boot (from localhost log). I have two questions, then. First, how do I get tomcat to use a single poilcy file, rather than the directory structure presented by policy.d/? Secondly, why, when I specify all files to use the same policy, do I still get the stack trace below? Stack trace: SEVERE: Servlet /myapp threw load() exception java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.org.apache.jasper) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:342) at java.security.AccessController.checkPermission(AccessController.java:553) at java.lang.SecurityManager.checkPermission(SecurityManager.java:549) at java.lang.SecurityManager.checkPackageAccess(SecurityManager.java:1529) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:291) at java.lang.ClassLoader.loadClass(ClassLoader.java:264) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1314) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1245) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:332) at org.apache.jasper.servlet.JspServlet.init(JspServlet.java:100) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.security.SecurityUtil$1.run(SecurityUtil.java:244) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAsPrivileged(Subject.java:537) at org.apache.catalina.security.SecurityUtil.execute(SecurityUtil.java:276) at org.apache.catalina.security.SecurityUtil.doAsPrivilege(SecurityUtil.java:162) at org.apache.catalina.security.SecurityUtil.doAsPrivilege(SecurityUtil.java:115) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1166) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:992) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4058) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4367) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:791) at org.apache.catalina.core.ContainerBase.access$000(ContainerBase.java:123) at org.apache.catalina.core.ContainerBase$PrivilegedAddChild.run(ContainerBase.java:145) at java.security.AccessController.doPrivileged(Native Method) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:769) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:525) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:978) at org.apache.catalina.startup.HostConfig.deployDirectories(HostConfig.java:941) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:499) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1201) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:318) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:117) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053) at org.apache.catalina.core.StandardHost.start(StandardHost.java:719) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:516) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:578) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.commons.daemon.support.DaemonLoader.start(DaemonLoader.java:177) Policy.d grant codeBase "file:${java.home}/lib/-" { permission java.security.AllPermission;

• Use XQuery to Access XML in Emacs

  - by Gregory Burd

  There you are working on a multi-MB/GB/TB XML document or set of documents, you want to be able to quickly query the content but you don't want to load the XML into a full-blown XML database, the time spent setting things up is simply too expensive. Why not combine a great open source editor, Emacs, and a great XML XQuery engine, Berkeley DB XML? That is exactly what Donnie Cameron did. Give it a try.

• SQL Server – SafePeak “Logon Trigger” Feature for Managing Data Access

  - by pinaldave

  Lately I received an interesting question about the abilities of SafePeak for SQL Server acceleration software: Q: “I would like to use SafePeak to make my CRM application faster. It is an application we bought from some vendor, after a while it became slow and we can’t reprogram it. SafePeak automated caching sounds like an easy and good solution for us. But, in my application there are many servers and different other applications services that address its main database, and some even change data, and I feel that there is a chance that some servers that during the connection process we may miss some. Is there a way to ensure that SafePeak will be aware of all connections to the SQL Server, so its cache will remain intact?” Interesting question, as I remember that SafePeak (http://www.safepeak.com/Product/SafePeak-Overview) likes that all traffic to the database will go thru it. I decided to check out the features of SafePeak latest version (2.1) and seek for an answer there. A: Indeed I found SafePeak has a feature they call “Logon Trigger” and is designed for that purpose. It is located in the user interface, under: Settings -> SQL instances management  ->  [your instance]  ->  [Logon Trigger] tab. From here you activate / deactivate it and control a white-list of enabled server IPs and Login names that SafePeak will ignore them. Click to Enlarge After activation of the “logon trigger” Safepeak server is notified by the SQL Server itself on each new opened connection. Safepeak monitors those connections and decides if there is something to do with them or not. On a typical installation SafePeak likes all application and users connections to go via SafePeak – this way it knows about data and schema updates immediately (real time). With activation of the safepeak “logon trigger”  a special CLR trigger is deployed on the SQL server and notifies Safepeak on any connection that has not arrived via SafePeak. In such cases Safepeak can act to clear and lock the cache or to ignore it. This feature enables to make sure SafePeak will be aware of all connections so SafePeak cache will maintain exactly correct all times. So even if a user, like a DBA will connect to the SQL Server not via SafePeak, SafePeak will know about it and take actions. The notification does not impact the work of that connection, the user or application still continue to do whatever they planned to do. Note: I found that activation of logon trigger in SafePeak requires that SafePeak SQL login will have the next permissions: 1) CONTROL SERVER; 2) VIEW SERVER STATE; 3) And the SQL Server instance is CLR enabled; Seeing SafePeak in action, I can say SafePeak brings fantastic resource for those who seek to get performance for SQL Server critical apps. SafePeak promises to accelerate SQL Server applications in just several hours of installation, automatic learning and some optimization configuration (no code changes!!!). If better application and database performance means better business to you – I suggest you to download and try SafePeak. The solution of SafePeak is indeed unique, and the questions I receive are very interesting. Have any more questions on SafePeak? Please leave your question as a comment and I will try to get an answer for you.

• Arrrg! MovieClip object refuses to moved in any rational way in as3?

  - by Aaron H.

  I have a MovieClip object, which is exported for actionscript (AS3) in an .swc file. When I place an instance of the clip on the stage without any modifications, it appears in the upper left corner, about half off stage (i.e. only the lower right quadrant of the object is visible). I understand that this is because the clip has a registration point which is not the upper left corner. If you call getBounds() on the movieclip you can get the bounds of the clip (presumably from the "point" that it's aligned on) which looks something like (left: -303, top: -100, right: 303, bottom: 100), you can subtract the left and top values from the clip x and y: clip.x -= bounds.left; clip.y -= bounds.top; This seems to properly align the clip fully on stage with the top left of the clip squarely in the corner of the stage. But! Following that logic doesn't seem to work when aligning it on the center of the stage! clip.x = (stage.stageWidth / 2); etc... This creates the crazy parallel universe where the clip is now down in the lower right corner of the stage. The only clue I have is that looking at: clip.transform.matrix and clip.transform.concatenatedMatrix matrix has a tx value of 748 (half of stage height) ty value of 426 (Half of stage height) concatenatedMatrix has a tx value of 1699.5 and ty value of 967.75 That's also obviously where the movieclip is getting positioned, but why? Where is this additional translation coming from?

• iPod touch has extremely slow wifi, drops packets - only on my router

  - by mskfisher

  I just purchased an iPod Touch. I am having a lot of trouble with its speeds on my Tenda W311R, but it has no speed problems on my neighbor's Netgear router. It will connect and authenticate to my network, but the Speed Test app from speedtest.net shows rates near 20-50 kbps. If I run the speed test immediately after powering the iPod on, it will get speeds of 10-20 Mbps, like it should - but the speeds slow down to the kbps range abut 10-15 seconds afterward. I get the same behavior with encryption and without encryption, and regardless of N, G, or B compatibility settings in the router. I've tried rebooting the iPod and resetting the network settings, but it's still slow. I've tried pinging the iPod from another computer, and it shows about 40% packet loss: $ ping 192.168.0.111 PING 192.168.0.111 (192.168.0.111): 56 data bytes 64 bytes from 192.168.0.111: icmp_seq=0 ttl=64 time=14.188 ms 64 bytes from 192.168.0.111: icmp_seq=1 ttl=64 time=11.556 ms 64 bytes from 192.168.0.111: icmp_seq=2 ttl=64 time=5.675 ms 64 bytes from 192.168.0.111: icmp_seq=3 ttl=64 time=5.721 ms Request timeout for icmp_seq 4 64 bytes from 192.168.0.111: icmp_seq=5 ttl=64 time=6.491 ms Request timeout for icmp_seq 6 64 bytes from 192.168.0.111: icmp_seq=7 ttl=64 time=8.065 ms Request timeout for icmp_seq 8 Request timeout for icmp_seq 9 Request timeout for icmp_seq 10 64 bytes from 192.168.0.111: icmp_seq=11 ttl=64 time=9.605 ms Signal strength is good - I'm never more than 20 feet from my access point, and it exhibits the same behavior if I'm standing next to the router. It works just well enough to receive text, but videos don't work at all. App downloads are hit and miss. I've tweaked just about all of the settings I can see to tweak, and I'm at a loss. I have also been searching Google for the past three days, all to no avail. Any suggestions?

• how to access inaccessible mac os x hard drive via ubuntu

  - by jon

  Background: My intention was to load a Virtual Machine (VM) on my Mac OS X Snow Leopard. My Mac had just enough room for a VM (my thought process was that VM was the same as partition) However, I burned the newest version of Ubuntu onto a CD, thinking that partitioning and running a virtual machine would be the same. I would restart my computer, booting up Ubuntu installer. The installation would not allow me to partition, forcing me to force shutdown my laptop. when I turn on my laptop, I see that my computer is "missing operating system". So, can someone help me fix my a) bootcamp, b) getting files and if a and b are fixed c) to install ubuntu as a VM?

• Wifi Drops Connections with WPA2-PSK

  - by graf_ignotiev

  I run a small computer lab made up of 10 computers of identical hardware and software (Dell Latitudes with Windows 7 x64 Enterprise) and I use a ZyWALL 2WG as a router/firewall. Nine of the computers connect to the router over wifi using WPA2-PSK encryption while the last one is connected by ethernet cable. I'm having a problem where any computer connected to the wi-fi occasionally drops off the network (it cannot be pinged and the client cannot ping the gateway). It only happens on the wifi side and only when the encryption is WPA2-PSK or WPA-PSK. I tried using another router with a different make and model and had no problems. Thinking it could be a software error, I reset the router to factory defaults and installed the newest firmware (V4.04(AQI.8) | 04/09/2010), but still have the problem. The 802.1X log gives the following error User logout because of user disassociation. with this note WPA2-PSK:00242c582ece:logout where 00242c582ece is the mac address of the device. At this point I'm out of things to try and leads to follow. It looks like this user had the same or similar problem, but none of those proposed solutions work for me.

• Internet speed is suddenly slow only on my laptop, but it's normal in other devices

  - by Wael

  I have a TP-Link router connected to a ZTE modem, with 2 laptops, a tablet, 2 phones connected via the router's WiFi, and an additional desktop connected via ethernet to the router. Today, my laptop started to have a very slow connection to the internet, which at first I thought it was the operator's problem to find out later on that it works fine on other devices. I tried to connect directly via WiFi to the modem, but it was as slow. I cannot access facebook at all, google takes forever to do a search, and youtube barely works. The weird thing though, is that when youtube does work, the streaming is full speed. This happens also when I download a file! My browse is Firefox, but I used Chrome and IE9 with the same results. I work on Windows 7 Thanks for any advices.

• Access PC Settings Easily from Your Desktop in Windows 8 and 8.1

  - by Akemi Iwaya

  Accessing your system’s settings in Windows 8 is not exactly the most straight-forward of processes, so if you need to change your settings often, then it can be a bit frustrating. With that in mind, the good folks over at 7 Tutorials have created an awesome shortcut that will take all the hassle out of accessing those settings, and make ‘tweaking’ Windows 8 much easier. After downloading the zip file, extract the exe file and place it in an appropriate folder, then create a shortcut. Once you have the new shortcut set up in the desired location (i.e. desktop or pinned to the taskbar), accessing your system’s settings has never been easier in Windows 8 and 8.1! Special Note: If you are someone who runs files through VirusTotal before using them, be aware that two listings there (Commtouch and Symantec) will flag the file as malware. We had no problems on our system whatsoever and believe the malware flags to be false positives. Download the Desktop Shortcut to PC Settings, for Windows 8 & 8.1 [7 Tutorials]
