• Using dnsmasq dns server on a laptop for a locally hosted tld

  - by kimausloos

  Hi, I'm running a working apache install with mod vhost_alias on a laptop. Everything works, but I have to manually add hosts in my /etc/hosts file. I'd like to install dnsmasq to point a tld to my local machine (this is not the problem, I know how to add a wildcard tld to dnsmasq), but how do I make it so that it will go look for other dns servers upstream? Remember I'm talking about a laptop, so I will be working on various wifi hotspots, with different default gateways, dns servers, etc. I've searched for quite some time but the only things I find are guides that require you to hardcode the upstream servers wich is a no-go for me. Any help is appreciated!

• Windows 8.1 killed notebook's wifi

  - by char1es

  Was running Windows 8 on a Lenovo G780 and updated to windows 8.1 Wifi does not work anymore, i always receive a dns server not responding error. I have tried using public dns servers from Google but with still no results. I've restarted my router with no results. All other devices on my network are having no trouble at all. I've tried updating the wireless driver but the manufacturers website claims that the Win8.1 driver should be updated with the update from windows. So i cant find a wireless driver... Anyone else having this error and does anyone have any ideas on how to fix it?? EDIT: here are the driver details: Broadcom 802.11n Network Adapter Provider: Microsoft Driver Date: 2013-05-31 Driver Version: 6.30.223.102 Digital Signer: Microsoft Windows Thanks

• Cannot Access IIS Website Locally Using www

  - by Reafidy

  I have small website hosted on our WS 2008 R2 server using IIS 7. I can access our website from anywhere in the world using: www.ourwebsite.co.nz But from any local computer on our internal network I can only access the website using: http://ourwebsite.co.nz Our employees are constantly asking why they cant just use www.ourwebsite.co.nz I'm not sure what info to provide. I presume that because the wesbite correctly functions from outside the local network that I have correctly setup our Web DNS A records at our domain host. And the problem may lie with our local DNS configuration.

• Custom/personal dyndns solution?

  - by Eddie Parker

  Hey: I can't think of how to make this work, but it seems like something that should be doable.. I currently own my own domain, and have been using dyndns.com's "custom DNS" to allow me to redirect 'example.com' to my website at home, which is on a dynamic IP. I've now switched over to a VPS solution which hosts my website and allows me root access to a box (me likey), which will now host "example.com" on a static IP. My question is, is it possible for me to somehow make "home.example.com" route to my box at home? Is there any software available that could automate updates to the DNS for this? Ideally I'd like not to pay a service if possible, but if that's the only way then I suppose I'll have to go that way. Thanks!

• Load-balancer options

  - by toolkit

  I am looking at a number of possible options for load-balancing. So far, I am constrained to the following options: DNS server load-balancer, balancing to a cluster of tomcat servers, with terracotta for session replication. Pros - don't have to buy new kit. Cons - DNS lb can keep directing to a broken server. Hardware load-balancer, direct to cluster of tomcat servers. Pros - could have second box for failover lb. Cons - expense. Apache server load-balancer. Pros - apache's lb polls for broken servers. Cons - apache server is single point of failure, plus need to buy another server. Are there any other options I should consider? Thanks. Update: Thanks for all the answers so far +1's all round. Not accepting an answer yet, to keep more ideas coming.

• Sharing laptop's internal optical drive running windows XP Media Center Edition with Netbook running

  - by Col

  just got a new HP netbook with no optical drive and guide said I should be able to share the optical drive of another windows computer. The netbook is running Windows 7 and the laptop, also HP, with the internal optical drive is running Windows XP Media Center Edition. I have wireless network that both the laptop and netbook access without a problem. The instructions did not seem to work in my case. When I right clicked on Properties of the optical drive and went to the Sharing tab, there was no selction for Advanced Sharing as the instructions said. XP made me go to Network wizard and set up a network, (which I already had). After doing that I could not access the drive from Windows 7. Has anyone benn able to do this?

• Software for monitoring internal software?

  - by Tyler Eaves

  Is there any good software for monitoring the health of a collection of related software? Requirements are as follows: Web-based, deployable on standard Linux/BSD software. Configurable to support a variety of processes, scheduled at various intervals. Some sort of dashboard interface, for monitoring status, viewing errors, etc. As an example, suppose we have a daily export that's scheduled to run at 6AM each morning. After the export completes, it would POST a status message, saying it had completed, passing in some sort of application key to identify the export. If that status message hadn't come in, by, say, 6:30AM, an e-mail might be sent, that application should go red on the dashboard, etc. Applications should also be able to post error/warning messages. Basically the goal is to be able to monitor all of our internal projects from one system, rather than a multitude of e-mails, log files, etc. I suspect that I'll probably have to end up writing this from scratch, but I just thought I'd ask.

• Set up internal domain to use external SMTP in Exchange 2007

  - by Geoffrey

  I'm moving to Google Apps and have setup dual-delivery. Everything is fine, but for mail sent internally (from [email protected] to [email protected]), Exchange is not using the send connectors I have pointing to Google's servers. I believe my question is similar to this question: How to force internal email through an smtp connector in exchange 2007 Again, if a user is connected to the Exchange server and tries to send to [email protected] it works just fine, but I cannot seem to force *@mydomain.com to route correctly. This should be a fairly simple, but according to this: google.com/support/forum/p/Google+Apps/thread?tid=30b6ad03baa57289&hl=en (can't post two links due to spam prevention) It does not seem possible. Any ideas?

• Issue with CNAME and Virtual Hosts

  - by mrc0der

  I'm using Apache and I have a CNAME DNS record for sub2.sub1.domain1.com that points to sub1.domain1.com And I have an A DNS record for sub1.domain1.com that points to the IP. Then in my httpd.conf file I have: <VirtualHost *:80> ServerName www.domain1.com DocumentRoot /domain1/www </VirtualHost> <VirtualHost *:80> ServerName sub1.domain.com DocumentRoot /domain1/sub1/www </VirtualHost> Yet I appear to be missing something, as when you visit sub2.sub1.domain1.com, it shows you the page for domain1.com. When you visit the sub1.domain1.com, it shows the correct page for sub1.

• Routing traffic to another internal network

  - by Jason

  OK, so here is the scenario. I have 4 Locations connected with an MPLS. I have installed an ASA at the primary location which is 10.20.1.0. Traffic is fine internally and to the world, however... I can't route traffic over the MPLS to another network. It is being blocked by an implicit deny rule even though there is a rule to allow any to any less secure interface (it should be using the same interface in/out, right?). I have a static route for the network in and the ASA can ping it - Just not traffic on the internal network of the ASA. -Jason

• www a-record vs cname-record

  - by Sorin Buturugeanu

  Hi! I have a website that I will be hosting DNS for (testing purposes at first and then it will have some limited traffic). I have set up DNS so that site.tld has an A record to the actual IP but I don't know what to do about www.site.tld. Both site.tld and www.site.tld will point to the same server / application so my logic tells me to add a cname record so that www.site.tld becomes an alias for site.tld, BUT, I've been checking my settings with intodns.com and if I only add a CNAME for the www.site.tld it gives me the following error: ERROR: I could not get any A records for www.cexa.ro! (the error clears once I do an A record for www.site.tld to point to the actual IP) I don't know if there is a "rule" that "www." should always be an A record even though it's actually pointing to the same IP / application. Thanks for helping me understand this!

• Unknown Host Error, is this a registrar problem or a host problem?

  - by jerrygarciuh

  Hi guys, I am dealing with a barrel of weasels on this one. Ad agency registered the domain in mid-August with Network Solutions. 72 hours ago I updated the DNS to point to a host provided by an associate of the client whose credentials are dubious. The DNS servers are at NETSONIC.NET (NS1 and NS2) and respond to ping no problem. I can FTP to the server using its IP but the name is no go. The name is also no go for tracert and ping: tracert voodoobbqfranchise.com Unable to resolve target system name voodoobbqfranchise.com. ping voodoobbqfranchise.com ping: unknown host voodoobbqfranchise.com I called NetSol and of course their tier one guy swears it must be the host but I insist that an unknown host must be a NetSol issue. Otherwise we'd get somethng like an httpd_conf error after being routed to the Netsonic server. Am I right? Is this an issue at the registrar? TIA JG

  - by basit.

  i have a site like twitter.com on server one and on server two i have forum, which path is like domain.com/forum on server one i wanted to implement wild card dns and put main domain on it. but on server two i wanted to keep forum separate, i cant give sub-domain forum.domain.com, because all its links are already put in search engines and link back to domain.com/forum. so i was wondering, how can i put domain and wild card dns on server one and still able to give path on server 2 for domain.com/forum (as sub-folder). any ideas? do you think htaccess can do that job? if yes, then how?

• ibm 8305-29u Sound comes from internal speaker instead of green port - Ubuntu 10.04 LTS

  - by TecBrat

  The title pretty much says it all. My experience w/ubuntu is VERY limited. I did find the system test feature and ran an audio test. It found my device as Intel 82801DB-ICH4. I wasn't getting anything. I tried a couple of things and don't really even remember what I tried, but I started getting audio (not just beeps) from the system's internal speaker. Any ideas? (I can't rule out a hardware problem. This box sat under my bed for a couple of years and it's first life was in an environment FULL of cement dust.)H

• IIS reveals internal IP address in content-location field - fix

  - by saille

  Referring: http://support.microsoft.com/kb/q218180/, there is a known issue in IIS4/5/6 whereby it will reveal the internal IP of a web server in the content-location field of the HTTP header. We have IIS 6. I have tried the fix suggested, but it has not worked. The website is configured to send all requests to ASP.NET, and I am wondering if this is why the fix, which addresses IIS configuration, has not worked for us. If this is the case, how would we fix this in ASP.NET? We need to fix this issue in order to pass a security audit.

• VMWare ESXi virtual machine can contact the gateway but not the DNS server

  - by Nathan Palmer

  I am having a bit of a strange issue. I have a VMWare ESXi server with two virtual machines running on it. They are running just fine and can communicate on the network without a problem. I am now trying to add a third. I am installing Ubuntu 8.04 Server. I assign it a static IP address and it's a fresh installation. Once installed I can ping the gateway but I cannot ping the DNS server. It's on the same network with the other two VMs which are communicating just fine. I have tried to reinstall the operating system but it still fails to connect. Here is /etc/network/interfaces auto eth0 iface eth0 inet static address 192.168.1.23 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 208.67.222.222 #opendns dns-search mydomain.com Here is route Destination | Gateway | Genmask | Flags | Metric | Ref | Use | Iface localnet | * | 255.255.255.0 | U | 0 | 0 | 0 | eth0 default | 192.168.1.1 | 0.0.0.0 | UG | 100 | 0 | 0 | eth0 Since I'm running this behind a FortiGate this is what the sniff command gives me when I try to ping 208.67.222.222 arp who-has 192.168.1.1 tell 192.168.1.23 arp reply 192.168.1.1 is-at MAC 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request As you can see it looks like I never get a response. One interesting thing I notice is the arp reply's MAC doesn't look right. I have cleared the FortiGate's ARP cache though and checked the entry and it seems correct. The MAC it lists is the one for the router. However if I ping from a different virtual machine that is also Ubuntu 8.04 with a nearly identical configuration I get this. 192.168.1.22 -> 208.67.222.222: icmp: echo request 208.67.222.222 -> 192.168.1.22: icmp: echo reply 192.168.1.22 -> 208.67.222.222: icmp: echo request 208.67.222.222 -> 192.168.1.22: icmp: echo reply 192.168.1.22 -> 208.67.222.222: icmp: echo request 208.67.222.222 -> 192.168.1.22: icmp: echo reply So, what could I be missing? Thanks.

• Certain clients (IP range) can not ping server

  - by Logman

  I just virtualized a Windows 2003 Server SP2 x32. The server contained our help desk server (Spiceworks) and our anti virus management server (ESET RAC). The host computer actually contained the virtualized server originally; I created the vhd and then I wiped this system clean and installed Windows 2008 R2 x64 Datacenter and added the virtualized 2003 onto the Hyper-V 2008 R2 Server. I got the server running fine except for... certain ip ranges. Local clients can get updates from the AV server from my 192.168.180.xxx & 192.168.181.xxx BUT NOT from any 192.168.182.xxx, 192.168.183.xxx, 192.168.184.xxx etc... I can not ping the server from any clients except for the 180. & 181. ranges. Now I created 2 other virtualized servers (win2008 & a win7 pro) and they exist on the same virtual host as the 2003 server. And at first I could not ping those until I went to the "\Network and Sharing Center\Advanced sharing settings" and Turned On File and Print Sharing. Then I could ping and access those virtualized guests. Win2003 server isn't quite the same. But I am sure I have it on. But now when I ping from a client on one of those ranges that would not work I get this: As you can see the ping leaves our network. We have 2 ad/dns servers (one 180. & the other in the 181. range). Is it DNS? Both AD/DNS servers are Windows 2003. And we plan on upgrading both to 2008 R2 within a month or two but I need to fix this issue pronto (esp the AV end). btw, I did rename that 2003 Server (Spiceworks/AV) hostname. And I tried a CNAME. But I do not think that is the problem. EDIT: OR because this server existed on this hardware/computer before becoming virtualized?

• Internal users can't receive email sent by application

  - by jdballard

  We have an application server that hosts a CRM application. It is using SMTP on it's own server to send emails. If I send an email using the application to [email protected], it shows up in my inbox. If I send an email to [email protected], it never shows up. It doesn't matter what address I put in for @MyCompanyDomain.com, they never get through. Any email addresses outside our domain/firewall get through. We're using Exchange 2007 and when I look at the message tracking logs, the missing messages don't show up there, either. Is there something I need to configure in Exchange or the SMTP server on the application server? I can't figure out why emails get outside the firewall but internal emails never show up. Thanks, Jeff

• Load balancing with rsync

  - by David

  i have 2 server with public ip: SERVER A - 10.10.10.11 SERVER B - 10.10.10.12 both of them are centos 6 in OS, installed nginx with php-fpm, 2 exact same website stored at: /var/www/html. Domain with: myxdomain.com and dns hosted with cloudflare ( since cloudflare do support round robin ) to point the domain to A record of 10.10.10.11 and 10.10.10.12. I know that round robin dns does not cover the failover or fallover, but it does not matter, what i need is: How do i sync the both content of /var/www/html server A and server B to be exactly same? Lets say: 1) user uploaded their file to server A, the file content will be sync to server B as well. 2) user uploaded their file to server B, the file content will be sync to server A as well. rsync will be good choice here? Any example of command line and cronjob time that suitable? thanks

• Apache - setting up a subdomain

  - by Adam

  I'm having trouble getting a subdomain working for an Apache Linux Install. Following is what I've configured: DNS: connect.goneglobal.com. CNAME 54.251.35.112 Apache httpd.conf: <VirtualHost *:80> DocumentRoot /var/www/html/connect.goneglobal.com ServerName connect.goneglobal.com </VirtualHost> restart httpd - this ip is registered to this server - works for other sites on this apache. (first time I've tried a subdomain). Appears the issue is with DNS potentially and it doesn't seem to get to the site. Note: I have an index.php in the Documentroot. Note: there is an A record for goneglobal.com. which goes to a different hosting provider. thx
