Networking :: How To Test If Bind9 Really Working
Dec 15, 2010
Set up a server with Bind, Dovecote, Apache etc. Registered a domain and made all the necessary things for it to work. The server can send/receive mail on my domain, but when I try to look up the site I have it returns a lookup failure. I know Apache is working as I can browse the site when I used my ip address but I can't when I use the domain name. Anyone got a few tricks I could try to dumb down and find the possible failures I did when setting this up?

I am migrating my server from Kloxo (lxadmin) to Ubuntu (webmin/virtualmin), and I already had my Nameservers on my register (Godaddy) to go to [URL] and [URL] along with my IP. (I set the ttl to 60 cuz I thought that might be a problem) Now, I do a dig [URL], it gives me this output.
Code:
; <<>> DiG 9.6.1-P2 <<>> thedomz.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 40276
[code]...
I can go to my website only when I change my hosts file (on my windows machine).

I have the following bind9 configuration, and I'm trying to resolve reverse lookup IP address to name.
$ttl 38400
mydomain.org.INSOAmyhosting.com. (
1243281304
10800
[code]...
** server can't find 1.2.3.4.in-addr.arpa: NXDOMAIN
Is my PTR wrong, or what do I need to have the reverse lookup working ?
Note: I replace real IP by 1.2.3.4, same for my domain name.

I have Ubuntu 9.10 PC on my home network acting as a VPN gateway. It is using vpnc & iptables to provide access to the remote network - other computers on my local network have routing rules in place to go via the Ubuntu gateway if trying to reach an IP on the remote network. This works just fine, except DNS lookups for names on the remote network don't work.
I'm trying to solve this by using Bind9 on the gateway, so it can act as DNS for the local network. I don't want to create excess VPN traffic or load on the remote DNS, so I want the gateway to forward the lookup to my ISPs DNS first and if the name is not found then try the remote network DNS. Is this possible, or is there another (better) way around this? The Bind9 configs seem to admit multiple DNSs, but use them in a failover sense - only using secondary DNSs when the first one in the list is not reachable at all.

when i try to set up bind9 to resolve the top level of the name it cant do it. for current sake of arguement i have 4 servers on the network
192.168.0.200 diana.undernets.lan
192.168.0.201 jen.undernets.lan
192.168.0.202 amanda.undernets.lan
192.168.0.203 alex.undernets.lan
those are the IP addresses of the servers and their respective hostnames
so if i send a request for anything to just undernets.lan it will fail because there is no record for that. so i added this to the bottom of the zone record
Code:
IN CNAME amanda
thinking that a blank would refer to the top of the zone
here is my named.conf.local which is called in my named.conf
Code:
zone "undernets.lan" {
type master;
file "/etc/bind/undernets.db";
};
zone "0.168.192.in-addr.arpa" {
[Code]....
i want to be able to lookup undernets.lan and it give me the IP address of amanda.undernets.lan

I'm trying to configure bind9 to block porn by having it pretend to be authoritative for a list of porn domains. It can then return a "fake" IP for the port sites, which points to a page on my server. So far, the only way I have found to do in this in bind requires a separate zone for each porn domain. This doesn't work because of memory problems - I have 1000's of porn domains to block.
I'd like to instead have bind forward queries to rbldnsd, which can take a list of domains in a "data set" file, and use it to return a single A record (pointing to my "access denied" page). However, I think this will not work because I would still need a separate "zone" for each porn domain name.

I have installed CentOS 5.5 final on VM ware 7.0 workstation.... and I was trying to install and configure bind9.. it installed alright but it refused to start because named.conf is not in the /etc/ directory. I have copied the template for /usr/share/doc/named/* to (/etc/ and /var/named/) the appropriate directory but it still fails but on it does not gives me any error message. Oh... least I forgot I was trying to configure it as a cache only server for now.

v10.4 {I have completely re-edited this thread because I have started over fresh. I am no longer using bind9, but now using the installation-defaults nameserver and dhcp and trying to get a handle on how things ought to be setup properly. My previous attempts was a disaster.}
Coming fresh out of a newly installed 10.4, I obviously was able to get network connectivity but then I ran into trouble the minute that I tried to change eth0/eth1 connections via network-manager's applet. What I found was, that when I attempted to define static connections, all bets were off. It seems that once one attempts to change eth0/eth1 which are wired devices, I was no longer able to recover my network connectivity!
I was however able to setup a wireless connection, so in this way I was able to get back network (and Internet) connectivity, and write this thread on this forum. I notice also, that there is no longer 'Networks' in the System->Administration menus! Geez, what the hell is going on? how to properly configure my static wired connection? Networks in 10.4 have really changed alot!

I was trying to make a skype call to someone. However, I can hear them, but they can't hear me. I did a skype sound test. And discovered it was my mic not working. However, I can't see any configuration to see if my mic is muted or not.

I'd like to ask you if there is a way to test if RAM modules are working/stable. I don't mean memtest86+ test, my previous motherboard crashed after inserting another module (problem could not be specified/or/and was in RAM, so I got new ones from seller). So now I'd like to ask you, if there is some way to determine if RAMs are working and stable. I don't know any other way than applying them to them motherboard and testing, but now it really is not what I want to do. Maybe there could be some device which can test them, or something.

So I activated the Firefox profile:
Code:
And restarted Firefox (even rebooted), but it doesn't seem to be working. When I open Firefox I am able to perform a "Save Page As" in locations I shouldn't be able to, like my Desktop or Pictures folder.
The following command says the Firefox process is in enforce mode:
Code:
Of the following lines, the only directory which is "rw" is /Downloads, why am I still able to write to other places?
Code:
OS: Ubuntu 10.10
Can someone with an active Firefox profile do this simple test for me? Click File -> Save As and try to save somewhere the Apparmor profile shouldn't let you, and let me know the results.

Basically, it is a Bluetooth scanner that is designed to do just one thing, scan for discoverable devices in range and record their MAC, name, and the time/date they were found to a log file. There are only a few options, it is pretty much a set it and forget it sort of thing. The only requirements are BlueZ (3.x or 4.x), and that your computer has a Bluetooth device that is supported by Linux.
Obviously you will also need at least one device to scan for, and the more the better. If you want to take a walk through your mall while running it and seeing what you found, I would be ecstatic. A word of warning, I am not a very good C programmer and I have no doubt that there are mistakes in the code and improvements that could be made. You can download the source and get a little more specific information about it from: [URL].

I have an issue with Skype video similar to this thread [URL] where the test video doesn't work and I only see a white screen from my own webcam. The receivers can see my video and I can see their video, however. Video from my webcam works fine in Cheese and Guvcview. It seemed to start after I loaded the Compiz-config-settings-manager in an effort to fix video tearing (didn't work). Also Kdenlive now crashes every time I try to run a clip, but it was working great before. Even if I remove CompizConfig I still have the problem.

I have a Logitech ClearChat Stereo headset, and can hear music playing with the headset connected to the PC speakers (external Logitech). Have setup Empathy to be able to talk to someone using Google Talk. It seems to have been setup correctly, as I can see 2 contacts in the offline list. I don't have PulseAudio installed (I think ??), and can see only System | Preferences | Sound , which doesn't show me much. Here are the settings at present (inboard audio card) ..
Code:
:~$ sudo aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0 .....
How can I test that the microphone is working correctly?

Dell Mini 9 Netbook with Windows XP OS died. It has a 16GB SSD. I was in the middle of installing HP printer software when it shutdown unexpectedly. Then upon turning it back on it says something about a media test failure, check cable and then Operating System Not Found. I've been able to boot using Damn Small Linux using an external cd drive.
When I type 'fdisk -l' I get:
Disk /dev/hda: 15.4 GB, 15408046080 bytes
255 heads, 63 sectors/track, 1873 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/hda doesn't contain a valid partition table
My wife has lots of pictures on the drive that she would like so I took it to a couple data recovery places and they were charging anywhere from $1000 just for jpegs up to $2600 for all files retrieved. That's more than I can budget for this. So my wife accepted the fact that the pictures are gone, but I figured I might as well try what I can because we have nothing more to lose.
I thought I'd try to get a hard drive cubby and attach it through USB to a working PC, but apparently Dell's SSDs are proprietary and the design is not accommodated. I thought maybe just the partition table information got erased somehow, so I tried using gparted and it found nothing. Whenever I use cfdisk and create partitions, I quit cfdisk after writing and it still says there is no valid partition table. I have no other ideas as to what I can do.

I was windering, if you are writing a C program, I don't think you are supposed to commit the .o files and executables. How can you test your program without making a copy outside the git working dir?

I've a issue on Skype 2.1 beta, my Ubuntu version is Karmic Koala. Well, my camera works perfectly in guvcview and in skype test (I already modified config.xml in my user dir to have 640x480, my cam is Ricoh r5870). OK, as soon as I start my video or I get itautomatically started it goes 320x240 and very bad. I turn it off during the call and I restart it: it works perfectly. Could I solve this issue by telling skype to open the video "just like if it were the second time" ?
