• testdisk - recover partition table

  - by Evaggelos Balaskas

  I destroyed my partition table of my laptop.

• mysql INNODB inserts very slow

  - by 133794m3r

  The database's schema is as follows. CREATE TABLE `items` ( `id` mediumint( 8 ) unsigned NOT NULL AUTO_INCREMENT , `name` varchar( 45 ) NOT NULL , `main_type` tinyint( 4 ) NOT NULL , `rarity` tinyint( 4 ) NOT NULL , `stack_size` smallint( 6 ) NOT NULL , `sub_type` tinyint( 4 ) NOT NULL , `cost` mediumint( 8 ) unsigned NOT NULL , `ilvl` smallint( 6 ) unsigned NOT NULL DEFAULT '0', `flavor_text` varchar( 250 ) NOT NULL , `rlvl` tinyint( 3 ) unsigned NOT NULL , `final` tinyint( 4 ) NOT NULL DEFAULT '0', PRIMARY KEY ( `id` ) ) ENGINE = InnoDB DEFAULT CHARSET = ascii; Now, doing an insert on this table takes 0.22 seconds. I don't know why it's taking so long to do a single row insert. Reads are really really fast something like 0.005 seconds. With using the example configuration from here dev mysql innodb it averages ~0.002 to ~0.005 seconds. Why it takes more than 100x more time to do a single insert makes no sense to me. My computer is as follows. OS:Debian Sid x86-x64, Mysql 5.1, RAM:4GB ddr2, cpu 2.0Ghz dual core, HDD 7200RPM 32MB cache 640GB. Why it's taking almost 100x as much time for a SELECT * FROM items; vs INSERT INTO items ...; will never make any sense to me. It's still a small table at only 70 rows, and took that long even when it had 0 rows.

• Would an invalid certificate cause an 0x8004010F sync error?

  - by hydroparadise

  We just migrated from Exchange 2003 to 2007 which was a combo primary AD/DNS server and it has not gone smoothly. We are now down to getting a new certificate (a bureaucratic process thats out of my hands) and users getting the 0x8004010F sync issue. We are only using Outlook 2007 as our email client and the sync error appears exactly as so: 9:21:44 Synchronizer Version 12.0.6562 9:21:44 Synchronizing Mailbox '<User>' 9:21:44 Done 9:21:44 Microsoft Exchange offline address book 9:21:44 0X8004010F Now, I have read a number of technet articles on this issue anywhere from adding an A record in the DNS for autodiscover.domain.com to syncing the old OAD to the new OAD. In otherwords, theres lots of thing to try, but trial and error at this point might be hazardous to ther server's health and I am trying to narrow down the list of things to try. What has me thinking that the sync error could be related to the certificate is an event error message that says the following: Microsoft Exchange could not find a certificate that contains the domain name mail.ccufl.org in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Internet Mail with a FQDN parameter of mail.ccufl.org. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key. I am not fully clear on how the Exchange Transport Service is related to Syncronization, but my hunch is that it probably not related to there not being a valid certificate. So to recap, would an invalid certificate cause an 0x8004010F sync error?

• NAT confusion regarding cisco ASA5510

  - by LonelyLonelyNetworkN00b

  I'm setting up my first cisco firewalls. A little information first:I have two asa5510 setup in a working active/standby pair. From my ISP i have two public subnets. A /29 and a /26. On my DMZ interface i have the /26 configured. On my WAN Interface i have configured the /29 IPs. My isp routes the /26 via the /29 primary IP. I'm running ASA 8.2. I've turned NAT-Control off, because i don't want to use nat for for other than some internal interfaces. In essence i don't want to use NAT unless i specify it. I have a internal interface with the network of 192.168.100.0/24. I've tried setting up nat limke this: nat (inside) 1 192.168.100.0 255.255.255.0 global (WAN) 1 interface I was under the impression that this would let connections that was going from 192.168.100.0/24 and out the WAN interface to be Port-Address-translated. I'm not getting this to work for some reason. Inside interface has security level of 100, and wan has security level of 0.

• WSS Search fills 10 GB limit on SBS server 2011

  - by Kactus

  I've got a SBS Server 2011 Standard SP1 that isn't very busy. 2 Users local and 2 remote. We have sharepoint that has maybe a dozen small documents at most. I've just started getting the following two error occur Could not allocate space for object 'dbo.MSSBatchHistory'.'IX_MSSBatchHistory' in database 'WSS_Search_SERVER' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. And CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 10240 MB per database. Digging around in SQL manager I see that WSS Search DB file size is 10241MB, the log file is only 147 MB Firstly, why is WSS Search taking up so much space? How can I stop it from doing so, and what can I do now to get things running ok. I know about log file truncating and this isn't the case here since the log is tiny. Any help is appreciated. There is plenty of free space on the disk (791GB free) Thanks Kactus

• How can I recover a Fedora 12 installation that is showing signs of disk errors?

  - by Bob Cross

  I am currently overseas (i.e., very far from my normal library of tools) and my primary machine that would normally act as the data server in the performance test that we're trying to run is failing to boot to Fedora 12 properly. This is a machine that, as of yesterday, was booting fine. However, this morning, very strange portions of the boot process were complaining with messages such as "unexpected 0x0 in rpcbind" and "bad file descriptor" (I don't have the error in front of me - scavenged a windows installation to get onto serverfault). Eventually, the boot hung for a long time at the NFS service and then brought up what looked like the KDE login screen but neither the mouse nor keyboard functioned. In olden days, I would try to get to a point where I could manage to run fsck and pray that the bad sectors would come back into alignment just long enough for me to scrape the critical data off of the machine. However, now that we live in the future, it seems like our options in situations like this should be a little more varied. Is there a way to recover a Fedora 12 installation with bad disk sectors that won't boot properly? For completeness, I am comfortable working with bootable recovery distros-on-CD and such but I don't know which one is likely to work best with modern Fedora. In the absence of guidance, I'm frantically torrenting the Fedora 12 Live CD and DVD, hoping to try rescue mode before tomorrow morning.

• JBossMQ - Clustered Queues/NameNotFoundException: QueueConnectionFactory error

  - by mfarver

  I am trying to get an application working on a JBoss Cluster. It uses Queues internally, and the developer claims that it should work correctly in a clustered environment. I have jbossmq setup as a ha-singleton on the cluster. The application works correctly on whichever node currently is running the queue, but fails on the other nodes with a: "javax.naming.NameNotFoundException: QueueConnectionFactory not bound" error. I can look at JNDIview from the jmx-console and see that indeed the QueueConnectionFactory class only appears on the primary node in the Global context. Is there a way to see the Cluster's JNDI listing instead of each server? The steps I took from a default Jboss 4.2.3.GA installation were to use the "all" configuration. Then removed /server/all/deploy/hsqldb-ds.xml and /deploy-hasingleton/jms/hsqldb-jdbc2-service.xml, copying the example/jms/mysq-jdbc2-service.xml file into its place (editing that file to use DefaultDS instead of MySqlDS). Finally I created a mysql-ds.xml file in the deploy directory pointing "DefaultDS" at an empty database. I created a -services.xml file in the deploy directory with the queue definition. like the one below: <server> <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=myfirstqueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> </server> All of the other cluster features of working, the servers list each other in the view, and sessions are replicating back and forth. The JBoss documentation is somewhat light in this area, is there another setting I might have missed? Or is this likely to be a code issue (is there different code to do a JNDI lookup in a clusted environment?) Thanks

• Network Load Balancing and AnyCast Routing

  - by user126917

  Hi All can anyone advise on problems with the following? I am planning on installing the following setup on my estate: I have 2 sites that both have a large amount of users. Goals are to keep things simple for the users and to have automatic failover above the database level. Our Database will exist at the primary site and be async mirrored to the secondary site with manual failover procedures.The database generate sequential ID's so distributing it is not an option. I plan to site IIS boxes at both sites with all of the business logic on them and heavy operations. The connections to SQL will be lightweight and DB reads will be cached on IIS. On this layer I plan to use Windows network load balancing and have the same IP or IPs across all IIS boxes at both sites. This way there will be automatic failover and no single point of failure. Also users can have one web address regardless of which site they are in automatically be network load balanced to their local IIS. This is great but obviously our two sites are on different subnets and as this will be one IP address with most of our traffic we can't go broadcasting everything across the link between the sites. To solve this problem we plan to use AnyCast routing over our network layer to route the traffic to the most local box that is listening which will be defined by the network load balancing. Has anyone used this setup before? Can anyone think of any issues with this? Also some specifics I can't find anywhere at the moment. If my Windows box is assigned an IP and listening on that IP but network load balancing is not accepting specific traffic then will AnyCast route away from that? Also can I AnyCast on a socket level?

• Can I get a domain controller not to act as DNS for the members?

  - by rsw

  Hi, Let me try to explain my current setup. I have one linux machine acting as DHCP and DNS (dhcpd3 and bind) in my network. This works fine, all computers I hook up to the network gets an IP address and proper DNS servers set. Let's call it 10.12.0.10 However, we also have a Windows Server 2003 Domain Controller in our network to which we add our Windows computers (running XP), let's call it 10.12.0.20. I noticed that when I run 'nslookup' on one of the windows machines, it says that the primary DNS is 10.12.0.20. This have not been much of a problem since: The Windows clients are stationary The Windows server in itself point out my real DHCP/DNS, since I can reach everything specified in it However, this turns out to be a problem when we use Laptops. They connect to the domain here and gets a DNS server, but when the user travels or connect the computer from home, we hit a problem. They are connected to their internet, but their DNS is 10.12.0.20 which they can't reach since they're at home and not at the office network. I solved this by removing the register key called "NameServer" with the value 10.12.0.20, but it gets set again whenever they logon to the domain the next time (when they get back to the office). Can I somehow make the computers take whatever DNS server they are handed when connecting to the internet or a home network, instead of always trying to reach the Domain Controller?

• rc scripts dependencies

  - by chris

  On a Ubuntu 10.04.1 LTS server install certain services fail to start properly after a reboot. I have a couple of virtual interfaces defined on eth0: /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 172.16.5.240 netmask 255.255.255.0 gateway 172.16.5.1 auto eth0:1 iface eth0:1 inet static address 172.16.5.241 netmask 255.255.255.0 gateway 172.16.5.1 auto eth0:2 iface eth0:2 inet static address 172.16.5.242 netmask 255.255.255.0 gateway 172.16.5.1 auto eth0:3 iface eth0:3 inet static address 172.16.5.243 netmask 255.255.255.0 gateway 172.16.5.1 and so on... The services that try to bind to for example 172.16.5.243 fail during boot, complaining that there is no such IP address. My questions: 1) Are the services started parallel by default? Can I disable that so they run sequentially? 2) Is there a way to define dependencies between rc scripts? I'm only familiar with the defining the order of seqentially started scripts using the numbers in /etc/rc[0-6].d/) Any other fix or workaround appreciated.

• Microsoft Home Use Program - use more than one computer

  - by kristof

  I purchased a copy of MS Office through Microsoft Home Use Program (HUP) It basically allows you get a very cheap copy for home use if your employer owns the licence. My question is: Can I install it on more than one PC/laptop at home? I could not find anything in FAQ Thank you EDIT I was installing Office 2010 I found the following in the EULA: MICROSOFT SOFTWARE LICENSE TERMS .... 2 INSTALLATION AND USE RIGHTS. a. One Copy per Device. You may install one copy of the software on one device. That device is the “licensed device.” b. Licensed Device. You may only use one copy of the software on the licensed device at a time. c. Portable Device. You may install another copy of the software on a portable device for use by the single primary user of the licensed device. Here is the full copy of the licence

• Configuring ZenOSS to monitor CPU load

  - by Tom

  I'm trying test out monitoring tools for a network at work with a coworker but neither of us have ever used an sort of monitoring tools before. Currently we are experimenting with ZenOSS and having some difficulties. We want to populate our CPU load graphs because that is one of the primary feature we are looking for in our monitoring tools but we have been unable to populate the graphs with data. So far we have installed the wmipreformance, sqldatasource, wmidatasource, snmpperformance(simple) zenpacks and the machine we are trying to monitor is running Windows XP. We have tried to model the device and everything seems to run and we've tride to add data points to graphs but the only options we recieve for graphs are CPU and Memory. We are able to monitor services, ZenOSS recognizes the make and model of the processor, RAM, and Harddrive and is even giving us metrics on available storage but again, we are looking for performance metrics such as CPU load and Memory utilization. I realize I probably didn't provide a lot of information but that is because we don't have a very good idea of what we are doing and can't find instruction either on the ZenOSS homepage or forums to monitor CPU load. If someone could give us step by step instruction on how to set up CPU load monitoring that would probably be more beneficial to us than a diagnostic of our current setup, but regardless, if I left any important information out and you need it to answer the question, please let me know. Thank you.

• Is there a tool that can test what SSL/TLS cipher suites a particular website offers?

  - by Jeremy Powell

  Is there a tool that can test what SSL/TLS cipher suites a particular website offers?

This question is motivated by the security testing I do for PCI and general penetration testing. Update: GregS points out below that the SSL server picks from the cipher suites of the client. So it seems I would need to test all cipher suites one at a time. I think I can hack something together, but is there a tool that does particularly this?

• How to change my W2k8 System Partition?

  - by Chris May

  On my Windows 2008 server, my C: is 1.5 TB, and the partition is marked as: Healthy (Boot, Page File, Active, Crash Dump, Primary Partition) and somehow I ended up with a 2GB D: that is marked as Healthy (System). On this D: drive are only a few MB worth of files (bootmgr, boot folder, bootsect.bak), but all Windows files are on the c:. I've done everything I can to remove the (System) mark. I tried using bcdedit, I tried marking the C:partition as "Active", I tried using bootsect.exe to assign the C: drive as the boot partition. Maybe I didn't do one of those steps correct, but I've tried everything I can. When I got my new Dell Poweredge T710, I didn't bother removing their 2 small drives before I put in my 2 new large drives. So I think when I installed W2k8 Server, maybe dell left some bootable partition on their drives to help me install the OS, but I never used it and just booted right from the install CD. Can anyone help me remove the (System) mark from the D: so I can remove the D: partition and still boot to the C:? I know I could remove the D: drives and reinstall windows, but I'm trying to avoid a total reinstall.

• How can I get Windows 7 to work with two Nvidia graphics cards with different drivers?

  - by Max

  This is similar to this question, but I am using more similar cards with Windows 7. I just purchased a Zotac Nvidia GeForce 7200 GS. I have a motherboard with two PCI Express x16 slots. There is already an MSI Nvidia GeForce 8800 GTS being used as the primary card, driving two LCD monitors. I would like the Zotac to output to a TV via DVI-out. Unfortunately, when Windows detects the Zotac and installs its drivers, or I manually install them, Windows stops being able to boot up. If I remove them and re-install the MSI 8800 drivers, I can boot again, but Windows can no longer see the Zotac 7200--it shows up as a yellow triangle in Device Manager. I've read conflicting reports about this. Some people claim that Windows 7 will support multiple heterogeneous graphics card drivers, as long as they are all using the same driver API ("WDDM?"). Others say that they have to be using the exact same driver, or it won't work. Others claim that you have to use the exact same card. which is it, exactly? I know I can run the MSI 8800 in SLI if I purchase another, but I don't need that kind of power--I just need HD-out to my television. I read somewhere that running two cards in SLI precludes you from using 100% of their output ports, so I'm not sure if that's an option. I suppose I could also run two MSI 8800's without SLI, but again, that's more power than I need (and more money than I'd like to spend). Also, I don't think this exact model is even manufactured anymore. Any ideas?

• Is this a solution for having multiple SSL certificates on the same IP

  - by Saif Bechan

  I am running CentOS running on a VPS. I read some guides on having multiple SSL certificates on the same system, but I can not get the basics to work. The guide I got that makes the most sense to me is the doing the following. In CentOS I can make virtual NIC's. So I made 2 virtual NIC's to start with. 192.168.10.1, 192.168.10.2. Now I work in ISP manager Pro, so this is listening on my primary ip 1.1.1.1 For each website I have them listening on 192.168.10.1:80, 192.168.10.1:443 In the hosts file I made the following 2 entries 192.168.10.1 1st.com 192.168.10.2 2nd.com Now the strange thing is that when I browser to 1st.com I do not get the website located at 192.168.10.1, I get the website located at my prim IP 1.1.1.1 Should I do something like forwarding or routing for this setup to work? And the basic question: Will this setup even work? Are the SSL certificates based on the IP adress, or are the based on the host name, 1st.com and 2nd.com.

• Can I use a Windows Server 2003 Domain Controller but my home router for DNS?

  - by NetworkingWannabie

  Hi All Probably easiest to start with a description of my current setup, which works (oh, and this is a home setup not an office or anything): I have an ADSL modem with a static IP address (192.168.128.1), and its DHCP capability is disabled. I have a permanently powered up Windows Server 2003 machine with a fixed IP (192.168.128.2) which provides my domain controller, dhcp, and dns. The default gateway for everything is my ADSL modem everything is setup to use the WS2003 machine as the primary DNS with the ADSL modem as Secondary DNS just in case the server goes down (everything includes the server itself). Lastly, just in case it's relevant, I have my DHCP leases set to infinite (or whatever the right term is). Everything is pretty hunky dory. Except, that is, for the fact that my server is ALWAYS on, and it isn't always used, so I'm burning juice that I don't need to - my server burns around 120W which isn't immense but isn't irrelevant either, so I'd like to put it into a stand-by state when it isn't being used (the more standby the better) and then get the clients to wake it up. Am I correct in assuming that this won't work at the moment - A given client would need an IP address to wake the machine up, and it needs to machine to be awake to get an IP - catch 22? Assuming I'm correct, can I move to using my router (which is always on) for DHCP? What impact will this have on DC and DNS? Alternatively, does anyone have a better way for me to achieve this? Can I get the server to wake up when it sees clients look for a DHCP server, etc? Wow, that came out longer than expected! Thanks for your help.

  - by Zephyr Pellerin

  I'm currently working in an IT position, where I do helpdesk stuff, and predominantly security related issues/consulting (In the loosest sense of the term) In-House and for Service-Contract clients (as the only/acting CCSP [I guess I should say only person with Cisco experience] in my organization). I've professionally written Kernel Mode drivers for a gaming company. Among other things that I'm proud to put on a resume. I think of myself as very reasonably qualified as a System Administrator, With excellent Cisco experience, among other things I think would make a good addition to almost any IT staff in need of a new employee. However, Something has always tripped me up - Human Resources. Let me explain, I decided to skip the university route - I'm immensely glad that I did, The computer science graduates that I've met and work with rarely know much of anything about Computers (Until they gain some 'real' experience), Even when asked about Theoretical Computing fundamentals they can rattle something off about Turing Completeness but rarely do they understand the mathematical underpinnings. In short, I think instead of going to college, I'd rather pick up some real world experience. However, Apparently, Employers rarely think the same way. A quick perusal of jobs through the standard job search engine yields nothing short of a conspiracy to exclude anyone without 'A Bachelors Degree in Computer Science or Equivalent'. Interviews I've had in the past have almost always been entangled with - 1. My Age (Which I can't really change) and 2. Lack of Degree. Employers frequently disregard the CCNA/CCSP, The experience I've gained through internships, My extensive experience in x86 assembly and C, among so many other things I like to think are valuable to employers - In lieu of the fact that I don't have a piece of paper. So, AS AN EMPLOYER - Is it even worth working on my CCIE? Or should I pad my resume with certifications that are easier to acquire (Like CISSP, MSCE, Network+, etc.). Or should I ditch the whole idea and head back to get a Mathematics or CS degree?

• How to Load Balance 2 Internet Connections on a Windows 7 machine?

  - by Jimmy Chandra

  It's sort of related to this particular question, but that one is on Mac. I am looking for similar solution on Windows 7. I have 2 network connections: (Connection A) Wireless terminal connecting to ISP A (3G / EVDO internet provider) (Connection B) Broadband wired connection connecting to ISP B (Cable internet provider) Both has access to the internet. When I try connecting to a website and checking the networking tab on my Task Manager, I only see the network traffic being routed to only Connection A. Is there a way to make the computer to utilize both network (in a sense using all the bandwidth available from both the Cable ISP and the 3G / EVDO ISP) at the same time? If so, what do I need to do to set this up ... on Windows 7? Here is a bit more info on my network connections (ipconfig /all): PPP adapter Wireless Terminal: IPv4: aa.bb.ccc.ddd(preferred) Subnet mask: 255.255.255.255 Default Gateway: 0.0.0.0 DNS: aa.ee.f.ggg aa.ee.f.hhh Primary Wins: jjj.ii.k.l Secondary Wins: jjj.ii.k.m Ethernet adapter LAN: IPv4: 192.168.1.100 (connected to a router by wired that itself connect to a cable modem) subnet mask: 255.255.255.0 Default gateway: 192.168.1.1 (the wireless router) DHCP: 192.168.1.1 (the wireless router) DNS: xxx.yy.zz.ww rr.sss.t.uuu For my own privacy, I don't believe the actual number matters, the patterns are representative of the ip numbering scheme...

• Powershell script to delete secondary SMTP addresses of Exchange 2010 Mail Contacts

  - by Zero Subnet

  I have a few thousand Exchange 2010 Mail Contacts who get erroneously assigned internal SMTP addresses by the default recipient policy. I'm trying to use the following command to delete these addresses (keeping the primary SMTP) and disabling the automatic update from recipient policy so the SMTP addresses don't get recreated again. Get-MailContact -OrganizationalUnit "domain.local/OU" -Filter {EmailAddresses -like *@domain.local -and name -notlike "ExchangeUM*"} -ResultSize unlimited -IgnoreDefaultScope | foreach {$contact = $_; $email = $contact.emailaddresses; $email | foreach {if ($_.smtpaddress -like *@domain.local) {$address = $_.smtpaddress; write-host "Removing address" $address "from Contact" $contact.name; Set-Mailcontact -Identity $contact.identity -EmailAddresses @{Remove=$address}; $contact | set-mailcontact -emailaddresspolicyenabled $false} }} I'm getting the following error though: You must provide a value expression on the right-hand side of the '-like' operator.

• Configuration for httphandler in classic mode

  - by happyspider

  I have to install an httphandler that needs to run on classic mode. I have created an application on the iis that uses a classic apppool and put the handler assembly there. The vendor gave me a configuration in the deployment document that looks like this: <system.web> <globalization requestEncoding="iso-8859-1" responseEncoding="iso-8859-1" /> <httpModules> </httpModules> <httpHandlers> <add verb="*" path="*" type="ProductName.ProductName, ProductName" /> </httpHandlers> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <handlers> <add name="someUnspecificName" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv2.0,bitness32" /> </handlers> </system.webServer> The error I get when requesting a URL on the application is a 404, so I guess the handle is not used at all. Does the configuration look ok for a 64bit system?

• mysqld crashes on any statement

  - by ??iu

  I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement.

• Monitor is flashing through camera but not in the naked eye

  - by odyodyodys

  Two monitors: Samsung T23C350 - Samsung 2243NW Lets call the first A and the other B. A is a LED monitor with a 2ms response time (in specs) with a native resolution of 1920*1080@60Hz B is an older not-led one with 5ms response in specs with a resolution of 1680*1050@60Hz In the attached images and video you'll see that A (on the LEFT) is flickering but this is not visible to the naked eye. I took some pictures and videos with a camera and a mobile phone. This is also happening to all digital camcorders I've tested. A has a setting response time with values normal, fast, fastest. No matter the setting, the effect is the same. A on the left and B on the right. You can see the flickering, although both are @60Hz A video where you can see both monitors. A is always the left monitor. Another video where you can see what my digital camera sees. Another thing is that I managed to get a picture where the left monitor is completely black whilst the right one is displaying fine. This proves that the monitor is continuously flashing. My question is: Is this normal behavior and what is causing it? Am I affected by this fast flickering? I am using this as my primary monitor and as a programmer I have to keep my eyes on it for hours.

• Troubleshooting wireless client-bridged networks between two DD-WRT routers?

  - by KronoS

  I recently purchased a Buffalo N600 wireless router which came with DD-WRT pre-installed. I want to take my old wireless router a Linksys WRT54GL, also with DD-WRT pre-installed, and use it as a wireless bridge for my HTPC and Blu-Ray Player in the other room. I other words, I'm trying to connect to WIRED networks via the wireless on the routers. I followed eactly the instruction from DD-WRT's manual for 'Client Bridged' however I'm still not able to connect to two routers correctly, when the encryption is enabled (WPA2-Personal Mixed) however I am able to connect the two routers when there is NO encryption. I've checked, double checked, and triple checked that EVERYTHING is the same on BOTH routers: Routers 1 & 2 Encryption: WPA2-Personal Mixed Wireless Mode: G-Only Wireless Channel: 6 Subnet Mask: 255.255.255.0 Subnet: 192.168.1.0/254 SSID: Krono$ Primary Router #1 (Buffalo N600) IP Address: 192.168.1.1 Firewall: Enables w/ defaults DCHP: Enabled as DHCP Server Secondary Router #2 (Linksys WRT54GL) IP Address: 192.168.1.2 Firewall: Disabled as per DD-WRT instructions I'm looking for any configurations that I may have missed, or settings that may need to happen in order for this work.

• Server 2003 PDC DNS not working..Failover server is...

  - by Seth

  In the midst of trying to utilize proc power, i create a fault tolerant DNS server a while ago. Since, Ive been trying to add another controller for exchange. So I thought I would revert back to a single primary DNS for the meantime and now Im balancing on a thread. The server i thought I uninstalled DNS, is still acting as DNS. And now the PDC does not resolve. Can anybody walk me through, Im overwhelmed and cant think straight... Im afraid if anyone restarts their machine they wont have internet. Update Ok so from the beginning. I was configuring Exchange on a new server 2008. How it happened I dont know, but it started to not resolve DNS. (exclamation mark on NIC) even though everything was static. So ultimately I decided to remove the server from the problem, because I noticed DNS was in disarray if I used the DNS IP of the first server. This is when I tested with nslookup on each DNS server. I had uninstalled DNS from the second server, but nslookup was still resolving with that IPaddress, which has me all wound up cause I dont understand. So, since the first DNS server isn't resolving, Im assuming if the second one isnt configured right I'll loose internet. Im just confused and dont know where to start troubleshooting...
