• Ubuntu 12.04 Very slow especially with Android Studio

  - by Nada

  I have an old laptop with the following specification: Memory: 485 MiB, Processor: Genuine intel CPU T2300 @ 1.66 GHz ×2, OS Type: 32 bit, Disk: 78.1 GB, I installed on it Ubuntu 12.04 LTS and I noticed that the overall system is very slow in responding. I tried to search about that in the internet and I found some articles talking about how to make Ubuntu 12.04 LTS run fast I applied all what they said including download LXDE desktop environment and then nothing different in the system response time. Then I need to develop some android applications so, I download Android Studio (Beta) 0.8.6. The problem became worse than before whenever I tried to open the Android Studio the screen is frozen for some minutes then it took time to download the projects and initialize the work space also, when I tried to move the cursor he is move very slowly. When I tried to run my first application on the AVD it took three hours and still not run yet. I delete the Android Studio and install it again several times, I was trying to solve the problem but still nothing change. Please if you have any suggestions that may help me make my laptop and Android Studio work faster I will appreciate it for you. Thank you in advance.

• Win7 Hangs During App Install/Upgrade/Uninstall

  - by JadeMason

  I have a custom built PC that intermittently hangs when installing, uninstalling, or upgrading applications. Technical Specs ASUS P5E w/ WiFi Motherboard Intel Core2 Quad Q6600 Processor 4x 2GB G.Skill DDR2 800 SDRAM ASUS EAH2900XT / Radeon HD 2900XT 512MB Video Card Under normal operation the machine runs reliably, even under heavy load, such as video transcoding. The temperature never gets anywhere near where I would worry about it. However, the machine regularly hangs (complete lockup, no response to keyboard or mouse, no activity on-screen) when either installing a new application, uninstalling an existing application, or applying patches to existing applications or the OS. This is extremely frustrating as this machine is primarily used as a HTPC. Several apps are configured for automatic updates, and these updates sometimes cause the machine to lockup while we are watching content on the PC. In previously investigating this issue, I found one likely problem could be my Logitech Webcam. The Logitech software has a bug that leaves an entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\SessionManager\PendingFileRenameOperations Which references the Temp directory. My registry contained this error, so I uninstalled the webcam software and deleted this registry key value. Unfortunately, the machine will still intermittently hang. I've noticed that the hangs always happen when an install/upgrade/uninstall requires elevated privileges (presumably to modify the registry). I can typically get at least one install/upgrade/uninstall to complete after a reboot, but after that it is a game of russian roulette to see if the operation will succeed or hang the machine. The event log is not helpful, as log messages end at the time of the hang, with no record of a warning or error. My only recourse when the machine hangs in this way is to perform a hard reset/power cycle. Any tips on how to further debug this issue are greatly appreciated.

• Computer hangs at BIOS screen. Cannot enter setup.

  - by d2jxp

  I have an HP Pavilion a6500f (it's a year out of warranty) and it's hanging on the blue HP BIOS screen. If I mash F10 while it's starting up, it will say "Entering Setup..." but I will see no results. It will hang there and not do anything. If I actually wait until I can see the screen and then hit F10, there's no response at all and the computer will sit at the BIOS menu. I've dusted and cleaned it out, reseated the memory, switched the RAM slots, and reset the CMOS battery using the reset jumper. I'm out of ideas. I'm pretty sure it's not a hard drive issue, since my problem is at the BIOS. After this post, I'll disconnect the hard drive and try to just boot without it. Anyone have any other ideas? Edit: Okay, so I tried disconnecting the hard drive and now I can get back into the BIOS. I reconnected it and I'm locked out again. So the problem is my hard drive.. I guess I should delete this post unless someone has any ideas as to what's wrong with the drive?

• 100% CPU when doing 4 or more concurrent requests with Magento

  - by pancake

  Currently I'm having trouble with a server running Magento, it's unbelievably slow. It's a VPS with a few Magento installations on it used for development, so I'm the only one using them. When I do 4 request all 2 seconds after each other I'm finished in 10 seconds. Slow, but still within the limits of my patience. When I do 4 "concurrent" requests, however (opening 4 tabs in a row, very quickly) all four cores go to 100% and stay there for like a minute. How is this possible? I know that there are a lot of possibilities here, so any tips on how to make an Apache/PHP server go faster are also welcome. It used to go a lot faster before, and I've also tried APC, but it kept causing problems (PHP errors, something with memory pools) so I've disabled it. By the way, the Magento cache is off and compiling is also off. I know this makes Magento slower than usual, but I don't think a 60 second response time is normal for any Magento installation. Virtual hardware: 4 Cores and 4096MB RAM Swap is never used (checked with htop) 100GB disk space, of which 10% is in use Software: Debian 6 DirectAdmin and apache custombuild PHP 5.2.17 (CLI) If you need more info, please tell me how to get it, because I probably don't know how. I do know how to use the command line in linux and the usage of quite a few commands, but my experience with managing a server is limited.

• Correct use of SMTP "Sender" header?

  - by Eric Rath

  Our web application sends email messages to people when someone posts new content. Both sender and recipient have opted into receiving email messages from our application. When preparing such a message, we set the following SMTP headers: FROM: [email protected] TO: [email protected] SENDER: [email protected] We chose to use the author's email address in the FROM header in an attempt to provide the best experience for the recipient; when they see the message in their mail client, the author is clear. To avoid the appearance of spoofing, we added the SENDER header (with our own company email address) to make it clear that we sent the message on the author's behalf. After reading RFCs 822 and 2822, this seems to be an intended use of the sender header. Most receiving mail servers seem to handle this well; the email message is delivered normally (assuming the recipient mailbox exists, is not over quota, etc). However, when sending a message FROM an address in a domain TO an address in the same domain, some receiving domains reject the messages with a response like: 571 incorrect IP - psmtp (in reply to RCPT TO command) I think this means the receiving server only saw that the FROM header address was in its own domain, and that the message originated from a server it didn't consider authorized to send messages for that domain. In other words, the receiving server ignored the SENDER header. We have a workaround in place: the webapp keeps a list of such domains that seem to ignore the SENDER header, and when the FROM and TO headers are both in such a domain, it sets the FROM header to our own email address instead. But this list requires maintenance. Is there a better way to achieve the desired experience? We'd like to be a "good citizen" of the net, and all parties involved -- senders and recipients -- want to participate and receive these messages. One alternative is to always use our company email address in the FROM header, and prepend the author's name/address to the subject, but this seems a little clumsy.

• Apache Redirect is redirecting all HTTP instead of just one subdomain

  - by David Kaczynski

  All HTTP requests, such as http://example.com, are getting redirected to https://redmine.example.com, but I only want http://redmine.example.com to be redirected. For example, requests for I have the following in my 000-default configuration: <VirtualHost *:80> ServerName redmine.example.com DocumentRoot /usr/share/redmine/public Redirect permanent / https://redmine.example.com </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> . . . </VirtualHost> Here is my default-ssl configuration: <VirtualHost *:443> ServerName redmine.example.com DocumentRoot /usr/share/redmine/public SSLEngine on SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key BrowserMatch "MSIE [2-6]" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown <Directory /usr/share/redmine/public> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> LogLevel info ErrorLog /var/log/apache2/redmine-error.log CustomLog /var/log/apache2/redmine-access.log combined </VirtualHost> <VirtualHost *:443> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> . . . </VirtualHost> Is there anything here that is cause all HTTP requests to be redirected to https://redmine.example.com?

• 100% uptime for a web application

  - by Chris Lively

  We received an interesting "requirement" from a client today. They want 100% uptime with off-site failover on a web application. From our web application's viewpoint, this isn't an issue. It was designed to be able to scale out across multiple database servers, etc. However, from a networking issue I just can't seem to figure out how to make it work. In a nutshell, the application will live on servers within the client's network. It is accessed by both internal and external people. They want us to maintain an off-site copy of the system that in the event of a serious failure at their premises would immediately pick up and take over. Now we know there is absolutely no way to resolve it for internal people (carrier pigeon?), but they want the external users to not even notice. Quite frankly, I haven't the foggiest idea of how this might be possible. It seems that if they lose Internet connectivity then we would have to do a DNS change to forward traffic to the external machines... Which, of course, takes time. Ideas? UPDATE I had a discussion with the client today and they clarified on the issue. They stuck by the 100% number, saying the application should stay active even in the event of a flood. However, that requirement only kicks in if we host it for them. They said they would handle the uptime requirement if the application lives entirely on their servers. You can guess my response.

• Siege - running a stress test benchmark

  - by morgoth84

  I need to do a benchmark test of a HTTPS server using Siege, to see how it behaves under massive load. I'm initiating tests from another machine which is quite powerful and it is connected to the same physical switch the server is connected on. But when I initiate a test, I can't get it to make more than 170 requests per second. With this load the server's CPU usage is at 15-20% and the average response time for a request is approx. 0.03 seconds. Load of the client machine is approx. at 10%. So, I gradually increase the number of users in Siege (the number of worker threads) and request rate linearly increases up to 170 reqs/sec, but it never gets over it. No matter how many more worker threads I start, the load on the server is never more than 20% (and the client's load also doesn't increase any more). How can I overcome this? I've googled a bit and found out that after a request is completed, a socket associated with one ephermal port remains in WAIT_TIME state for some time during which it can't be reused. I tried to overcome this by doing these things: sysctl -w net.ipv4.ip_local_port_range="1024 65535" echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle Oh, and the client machine is a Linux (RedHat, I think, but I'm not sure). Any help would be appreciated.

• Basic IPTables setup for OpenVPN/HTTP/HTTPS server

  - by Afronautica

  I'm trying to get a basic IPTables setup on my server which will allow HTTP/SSH access, as well as enable the use of the server as an OpenVPN tunnel. The following is my current rule setup - the problem is OpenVPN queries (port 1194) seemed to be getting dropped as a result of this ruleset. Pinging a website while logged into the VPN results in teh response: Request timeout for icmp_seq 1 92 bytes from 10.8.0.1: Destination Port Unreachable When I clear the IPTable rules pinging from the VPN works fine.

• Does having TRIM enabled affect other hard drives on a computer (and how do you know when Windows is using it)?

  - by Breakthrough

  I recently purchased a solid state drive (an OCZ Vertex 2 (80 GB)) to use as my primary operating system partition. I also have three other SATA hard drives of assorted sizes. I successfully installed Windows 7 Professional onto the SSD (works awesome, great response time and transfer rate), and used the other three HDDs for data storage. I was browsing through the Bible of OCZ SSDs, and noticed the following in Section 60-76 - Tweaks and TRIM: Q. How do I know if TRIM is enabled on my OCZ SSD? A. In Windows 7, go to start/run/cmd), type the following: fsutil.exe behaviour query DisableDeleteNotify It should respond back with: DisableDeleteNotify=0 if TRIM support is ready and active. If it's not, then type: fsutil.exe behavior set DisableDeleteNotify 0 After a bit of searching on Google, I found similar results elsewhere (set DisableDeleteNotify to 0, which makes sense since for TRIM to work, the solid-state drive needs to be notified when deletes occur (for the garbage collector) unlike a normal hard drive). When I run the query on fsutil, I get the following result: DisableDeleteNotify = 48 Following the instructions I found, I set this to 0 instead of 48. However, I am beginning to wonder. Is this all the proof I really need that the OS is using TRIM? Also, since this applies globally for the computer, is TRIM data being sent to the other hard drives connected to the computer? And if so, would this cause any degradation in disk performance?

  I try to force encoding with IIS 7. When I add in the http response headers the key : Content-Type and value charset=utf-8 i got this key content-type : text/html,content-type=utf-8 it's there a way to remove the comma ? Thanks Justin for your answer. But it's seen don't work.

• VM load and ping problems after replacing server motherboard

  - by Andre

  Recently, we had to replace the motherboard of one of our servers. The procedure was done by IBM as it had guarantee. The server runs ESXi 5.1, with several virtual machines, including our main mail server (Domino) and a file server. After the replacing the motherboard and staring the VMs, ESXi asked us if we had moved it or copied (different motherboard is like a different computer). We clicked the latter. We started each machine and after some basic reconfiguration, all of them were up. However, we have been having problems with the mail server, it has been acting really slow at times (this could be when it syncs with the secondary mail server) and we have been checking with Centreon (a Nagios frontend) that its CPU load has been a bit high at times and ping response too. There was a moment this morning in which I tried connecting via SSH console and it was really slow to show login and basic commands like ifconfig and top. This particular mail server is a CentOS 4.4.7 64-bit. The little configuring we had to do after restarting it was to configure the network connection as it was resolving through DHCP. Our mail software is Lotus Notes server 9. Do you know of any way in which this replacement may be causing these difficulties, and how to fix it? Thanks.

• SQL Server 2008 Replication: Snap Shot Agent timing out on a specific table

  - by Nai

  Hi all, I am going through the process of setting up a transactional replication on my set up. However, I am unable to generate a full snap shot of my database. I keep getting stuck at the same particular point of the process. From snapshot agent: [46%] The process is running and is waiting for a response from the server Other sources have mentioned increasing the timeout period but I do not think this is the problem as this occurs at around the 10 min mark, way within the default value of 1800s. So, I removed that article/table from the snapshot, and lo and behold, it works. So I was looking at the Schema of the table and in my identity column, the NOT FOR REPLICATION was set to TRUE. All my other tables have it set to FALSE. Could this be the source of the error? Also, I tried changing this to false via the GUI but got received a timeout error. Is there a script that allows me to change this? Thanks all.

• How should I configure my Apache Hosts File to serve a different site for localhost than for my domain/publicip?

  - by rofls

  I'm trying to test out a LAMP (with PHP5 specifically) setup with Django already serving a website. I want to do the PHP stuff on localhost for now, so that when I do something like this: curl http://localhost/database/script.php?var=1, I get a response from the php server. Right now I'm getting a Django error. I tried something like this in the default file in sites-available: Listen 80 <VirtualHost aaa.bbb.ccc.ddd> ServerName localhost DocumentRoot /home/phpsite </VirtualHost> where aaa.bbb.ccc.ddd is the local ip address, and changing my actual site's settings to specify the public ip, like this: Listen 80 <VirtualHost www.xxx.yyy.zzz> ServerName mysite.com DocumentRoot /srv/www/mysite WSGIScriptAlias / /srv/www/mysite.wsgi </VirtualHost> but then I start getting all kinds of errors when I start apache, such as port ::[80] is already in use or something. I noticed that the hosts file that's located in /etc/apache2/ is apparently pointing everything to mysite.com, including my local ip as well as 127.0.0.1 and 127.0.1.1; Do I need to change the configuration there too?

• Redirection of outbound UDP port.

  - by pboin

  For my residential service, I changed ISPs to Zoom/Armstrong. Just after that, my NTP daemons stopped working. I dug deep and diagnosed the problem: Unprivileged ports are getting out. When i run 'ntpdate' for example, I go out on a high, unprivleged port, and get a response on UDP 123. That's fine. The 'ntpd' daemon though, expects to go out on 123 and get its reply there as well. This must be a common problem, because it's directly addressed in the NTP troubleshooting guide. Just to see what would happen, I wrote a detailed email to the general support address at Armstrong. They replied almost immediately with a complete technical answer! They have everything <1024 blocked, except for a few ports to support outbound VPN. So, the question: Can I use IPtables to essentially re-write my outbound UDP 123 up to 2123 or something like that? If I do, does there need to be a corresponding 2123-123 rule to translate the reply? This seems like NAT, but with ports, not addresses. I tried, but can't seem to get iptables to do what I want. I'm not sure if it's my lack of skill, or if I'm trying the wrong solution. True, I could run ntpdate from cron, but that loses all of the adjustment smarts of NTP.

• Block SMTP connections from mail domains which don't themselves accept SMTP connection.

  - by bignose

  I'm administrating a mail service for a small business. Their mail host's internet connection is an ADSL service with a permanent IP address. Unfortunately, many misconfigured mail systems will happily deliver to this host, but, when the host attempts to send mail back (e.g. a bounce notice, or a normal response from someone), the original sender refuses to receive connections from this host. That misconfiguration makes their system a one-way mail sender, which is a problem. How can I configure Postfix on this customer's mail host to refuse SMTP sessions that declare a sender domain which itself refuses SMTP from this host? That is, if the SMTP client declares a domain that we can't make SMTP connections back to, then there's not much point accepting the incoming connection in the first place. I'm imagining a late check (after the low-cost checks to winnow most of the rubbish connections) that keeps the client on the other end while it attempts an SMTP client connection back to the declared domain of the sender. If that connection is rejected, the incoming one is also rejected. I'm also open to other suggestions for how this problem might be addressed (short of not using this mail host at all, which isn't an option).

• Can next hop address be same as destination address?

  - by Raj

  Like if host address is 100.0.0.1 and next hop address is 100.0.0.2 and destination ip address is also 100.0.0.2 Is this a valid use case? Any real life usage? <dest ip> <next hop> ip route 100.0.0.2 255.255.255.255 100.0.0.2 weight 1 next-hop-vrf GlobalRouter Above is the command on a router inside a VRF. 100.0.0.2 is pingable from host. 100.0.0.1 & 100.0.0.2 are an ip address assigned to a VLAN on host & destination respectively. On a linux box, Such configuration is valid. [root]# netstat -r -n Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 55.55.55.55 55.55.55.55 255.255.255.255 UGH 0 0 0 eth0 [root]# ip route show 55.55.55.55 via 55.55.55.55 dev eth0 As per my understanding, If a destination IP is reachable (i.e in the same subnet of host IP) we dont need a next hop. I came across one application for using next hop for destination IP in same subnet (i.e for VPN) See this: Will packets send to the same subnet go through routers? If next hop != destination IP but they are in same subnet as that of host, is a valid scenario for VPN, then i am wondering what are the applications of next_hop==dest_ip & subnet same as host? This is my first post in Super User. Extremely happy with the quick and warm response.

• System randomly freezes yet mouse still moves

  - by user784446

  This problem has lasted for the past 48 hours. The first time it happened, a program I was running stopped responding, so I tried to end it from task manager. The processes at first were listed fine until hovered upon. Eventually, despite the mouse still being able to move, after a few persisting clicks the mouse finally stopped moving. The screen went blank shortly thereafter. The second time it occurred, items on the screen stopped responding - hovering over the taskbar or such wouldn't elicit a response. Sound would still play however. Eventually, the mouse became unresponsive and the system restarted itself. I suspect that it may be a problem of my SSD drive. After looking through some Google search results, I downloaded HDTunePro to determine if there's a problem with the drive. Results returned a problem of reallocated sector count. An error scan also revealed 48 bad sectors. Also, an attempt to backup the contents of the most important areas of the drive returned a few explorer "Error: cannot read source from disk" errors. Should I ditch the drive and use another drive or is there anything that can be done to repair the drive? SSD: OCZ Petrol 64gb CPU: AMD Athlon II X4 640 RAM: Generic 3GB DDR2 Motherboard: Gigabyte MA74GM-S2H OS: Windows 7 Ultimate x64 Thanks!

• Can't remote into Virtual PC

  - by Spamela

  I used to be able to remote into my Virtual PCs. It has been working for at least a year. Yesterday just stopped working... I cannot figure it out... Things I have triple-checked: 1. My Virtual PCs have "Allow Remote Access" checked. 2. My Virtual PCs have an account in the Administrator group that is password protected. 3. My Host's entry in the registry for the Terminal Services Port is still the default of 3389. So here is the strange thing. I can't even remote into the Virtual PC from it's host much less another PC... From the host, I can ping the Virtual PC and get a response but when trying to remote into it from the host I get the following error: Remote Desktop can't connect to the remote computer for one of these reasons: 1)Remote access to the server is not enabled. 2)The remote computer is turned off 3)The remote computer is not available on the network My host is running Windows 7. Virtual PCs are running XP. Thank you for looking at this!

• RAIDs with a lot of spindles - how to safely put to use the "wasted" space

  - by kubanczyk

  I have a fairly large number of RAID arrays (server controllers as well as midrange SAN storage) that all suffer from the same problem: barely enough spindles to keep the peak I/O performance, and tons of unused disk space. I guess it's a universal issue since vendors offer the smallest drives of 300 GB capacity but the random I/O performance hasn't really grown much since the time when the smallest drives were 36 GB. One example is a database that has 300 GB and needs random performance of 3200 IOPS, so it gets 16 disks (4800 GB minus 300 GB and we have 4.5 TB wasted space). Another common example are redo logs for a OLTP database that is sensitive in terms of response time. The redo logs get their own 300 GB mirror, but take 30 GB: 270 GB wasted. What I would like to see is a systematic approach for both Linux and Windows environment. How to set up the space so sysadmin team would be reminded about the risk of hindering the performance of the main db/app? Or, even better, to be protected from that risk? The typical situation that comes to my mind is "oh, I have this very large zip file, where do I uncompress it? Umm let's see the df -h and we figure something out in no time..." I don't put emphasis on strictness of the security (sysadmins are trusted to act in good faith), but on overall simplicity of the approach. For Linux, it would be great to have a filesystem customized to cap I/O rate to a very low level - is this possible?

• Help configuring Mercury mail or similiar with XAMPP to send e-mail outside of localhost

  - by user291040

  I'm building a PHP/MySQL driven website for my department at work (installed via XAMPP). I need to be able to send mail to outside e-mail addresses (e.g., Yahoo, Hotmail, etc.) using the PHP mail() function. As I see it I have to solutions: Configure the SMTP directive in php.ini to the server running at my work. Configure/run a mail server that can send e-mails outside of localhost (I'm trying Mercury because it comes installed with XAMPP). Here are problems I've come up against: I took a guess at our SMTP server name, and when calling PHP mail(), I get the error SMTP server response: 530 5.7.1 Client was not authenticated I can't be sure, however, the SMTP name is correct (I can't get help from our IT guys because of politics). I have tried to use mercury mail. Mercury seems to be picking up the request, but it doesn't want to forward the e-mail to the outside. I keep getting a Temporary error 240 (temporary MX resolution error). I've searched high and low but still can't find a definitive answer on how to send e-mails outside of localhost. Any help is greatly appreciated.

• virtual host settings fail on multiple sites

  - by Ricalsin

  Wow. I'm puzzled. On my ubuntu system I've setup an apache2 server and configured three virtual hosts in the /etc/apache2/sites-available directory. a2ensite to symbolic link the sites-enabled. The first two work great; a simple url of localhost.mysitenames.com works great for the first two sites, both finding their DocumentRoot and Directory paths. The third always generates a Bad Request (Invalid Hostname) response. No server error.log as it never hits it. I've copied/pasted the working vhost files, made the minor changes to the ServerName, DocumentRoot and Directory and the same problem persists. I always "sudo /etc/init.d/apache2 restart" whenever I make a change. I've cleared the browser cache as well. No love. There's not a limit to the number of sites you can host, right? My goal was a localhost development environment with the expectation I can run any number of websites locally before pushing them to a live server. Any thoughts on how to debug this? Or, just a simple solution I am missing?

• Join Domain from VM

  - by Adis

  I have two VMs running on VMWare Player. I use NAT adapter settings. The host machine for VMs is running on corporate network. First VM has Domain controller running and I can log in on that machine using domain credentials. I named domain wm.local When I run IP config on this machine: IP: 192.168.87.132 Def Gataway: 192.168.87.2 DNS server: 192.168.87.2 DHCP server: 192.168.87.254 Second VM cannot join domain. When I try it with domain WM I'm propmted for credentials. And I enter Administrator credentials and than it waits for some time and I get response: "The specified domain either does not exist or could not be contacted" If i type wm.local as domain when trying to join it does not prompt me to login but just shows "An Active Directory Domain Controller (AD DC) for the domain wm.local could not be contacted. And here it takes no time to get this error message. Ipconfig on this machine: IP: 192.168.87.134 Def Gataway: 192.168.87.2 DNS server: 192.168.87.2 DHCP server: 192.168.87.254 I can ping second VM from first one. And I disabled firewalls on both machines. Any ideas? Is there any manual for this?

• DNS caching server config problem

  - by Alex

  I have a Bind DNS caching-only server setup that is working. I am bringing up a new AD domain controller that will also be a DNS server for that AD but I don't want it responding to any DNS queries except those that are AD related. So, my goal is to leave this caching server as the primary DNS server for stations on the network and have it forward requests for the AD domain to the domain controller. My understanding is that I just need a forward zone for that domain pointing to the domain controller. However it does not seem to be working. So that leaves me to think that my caching server is not forwarding properly. For example, this AD is going to have a naming convention of hostname.mydomain.local. If I do an nslookup and specify the domain controller's IP address as the server, I can query addresses that exist in DNS on that server, such as dc1.mydomain.local. However, queries to my caching server times out (I get a response from the caching server if I query mydomain.local but none of the objects in that domain). Any suggestions? Here is my named.conf file: options { directory "/var/named"; listen-on { 192.168.0.14; 127.0.0.1; }; forwarders { ; ; }; forward first; }; zone "." in { type hint; file "db.cache"; }; zone "0.0.127.in-addr.arpa" in { type master; file "db.127.0.0"; }; //forward zone for mydomain.local zone "mydomain.local" { type forward; forwarders { 192.168.1.21; }; };
