Ubuntu Servers :: DNS Zone Delegation ?
Apr 28, 2011
I have an existing bind setup, which serves a local DNS zone: merlin.local.
I would like to setup a subzone, below merlin.local, (preferably ad.merlin.local) to be used by an M$ AD domain, and thus M$ DNS servers. I would like to then be able to lookup addresses in both of the zones mentioned from any machine on my network.
I thought that this would be as simple as creating a zone delegation in bind, however when I have done this, and setup an M$ domain using ad.merlin.local as it's DNS name. Whilst this hasn't presented me with any errors, as such, I have been unable to come up with a setup which allows me to lookup addresses in both the merlin.local domain and the ad.merlin domain. To be perfectly honest, I'm not sure what configuration I need to perform to allow this to happen, I stupidly assumed it would just work!

I successfully configured my local DNS server. I have server1.mydomain.com, pc1.mydomain.com and so on ..
The problem is that my website is hosted on an external server (not on the local network), so www.mydomain.com is not found in the configured zone/subnet
How can I tweak my DNS to fetch ALL subdomains from the gateway (just as it went before the DNS existed)?

I am trying to get bind 9 up and running on a new installation of server 10.04 and keep getting errors when starting the daemon -
* /etc/bind/named.conf.local:19: unknown option 'zone'
* /etc/bind/named.conf.local:20: unknown option 'zone'
* /etc/bind/named.conf.default-zones:3: unknown option 'zone'
* /etc/bind/named.conf.default-zones:11: unknown option 'zone'
* /etc/bind/named.conf.default-zones:16: unknown option 'zone'
* /etc/bind/named.conf.default-zones:21: unknown option 'zone'
* /etc/bind/named.conf.default-zones:26: unknown option 'zone'
The onlything I could find after scrubbing the internet is once ina while there's a missing bracket. But I have checked and triple checked my config files and the syntax and can't find anything wrong. I have another installation of bind9 running on Fedora and the same exact syntax works just fine.

I'm at a loss to why my reverse lookup zone doesn't work for me.I've got two views. One internal and one external. My domain is isp2.datornatverk.se. Public IP: 130.240.133.81.
dig -x @8.8.8.8 130.240.133.81
gives me:
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 2917
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
I've set it up so that the internal subnets gets the domains resolved to the internal IP-addresses. When querying from external addresses I will get public IP.My named.conf.local file:
Code:
acl internals {
127.0.0.0/8;[code]..........
I don't know whether the views has messed something up. It worked before I added the views.

I am planning to implement hardware load-balanced DNS servers. There will be one master and three slaves in the server farm. I will have two virtual servers associated with the server farm that will be listed as external nameservers for our domain.
BIND uses the list of NS records to determine the servers that need zone transfers. The zone NS records will not be the addresses of any of the real servers. How do I tell the master to do zone transfers to the real slave servers?

Has anyone else had trouble with Fedora 14s system-config-bind GUI for named. When I try to save my configuration, there is always an error something like.... "Zone has no adresses either A or AAAA"
Seems system-config-bind is broken is Fedora 14.

I want to change my time zone (not time, but the time zone). Just as an experiment.
I am GMT.
I go to /etc/timezone and enter US/Eastern.
I know that Gmail uses JavaScript to check the computers time zone (not the time). Therefore if I sent an e-mail from Gmail to myself at Gmail it should show the new time.
But it does not. It shows my GMT. Obviously Eastern time is behind GMT.
(The same happens if I just change the time using date -u). Gmail shows the GMT rather than the time a certain number of hours behind the GMT.
How can I set the time zone on my computer so that webmail like Gmail recognises the new time zone?

since the upgrade tzdata (2011c-0ubuntu0.10.04) to 2011d-0ubuntu0.10.04which I installed on Saturday, ntp updates seem to put me in GMT time.I've switched to manual time settings, as it does horrific things to my mythtv database!I'm not sure if its the upgrade, or the ntp time servers. My timezone is Australia/Tasmania.

I have Green Zone which I want to play on my computer. I have libdvdread4 and VLC media player and it has pulse and the whole 9 yards. It will only play the FBI warning. After playing it it won't transition to the next part. I guess I'll try on slow Windows. Also ubuntu needs a DirectX equivalent so you can play the movie on your desktop

I originally installed Kubuntu 7.10 on an ACER laptop (exact model escapes me at the moment) and subsequently upgraded to 9.10 and then to 10.04. Starting with 9.10, I had problems with the computer suddenly turning off in the middle of doing work. Eventually, I figured out that when this happened, the bottom panel had gotten quite warm so it probably a thermal control measure. Further, I discovered that I could prevent this by setting the power regulator to powersave, which effectively kept frequency scaling at 50% and under which I never had the computer suddenly turn, the only exceptions being when unplugged the computer and replugged it in and it would switch to dynamic power policy thus running at full power.
However, after "upgrading" to 10.04, I can't do anything to restrict frequency scaling. Whether I set the regulator to powersave, ondemand or anything, CPU frequency can go to full capacity until it heats the CPU to the critical trip point, invoking poweroff. Sometimes, this would happen just a few minutes after "acpi -t" reported 40C (is there some way to test the output from acpi, I've seen it report obviously wrong figures such as 0C when the room was considerably above freezing?). While trying to figure out what to do, I discovered the /proc/acpi/thermal directory and subsequently the /sys/dev/... directory.
I would like to know which directory I should focus on and what files in order to establish trip points and direct actions that will force the system to reduce heating so it won't reach critical. It's not like it's particularly compute intensive tasks triggering this. I have had it happen while running nothing more than the windowing system, system monitor, terminal and paging through a file with less. I have looked for documentation online but have not found anything that clearly explains what I need to do. The only parts I understand from what I've found are "[critical]: S5", "[active]", and "[passive]". The "[passive]" line included items like "tc=..." and "device=0x...", but I have no idea whatsoever what any of those settings do and the documents do absolutely nothing to explain them.
1) what file I need to edit, 2) what options I can set in the file, 3) what values those options can take and 4) what effects those values have on ACPI's behavior. Lastly, the default setting HAVE GOT TO BE CHANGED. Having poweroff as the first line of defense against overheating is simply UNACCEPTABLE. What would happen if this occurs during the middle of a system upgrade? I know at least enough to figure what needs to be done, even if I can't figure out how to do it. Many users can't even do that and I don't think they should have to. The installation process should automatically detect what methods of reducing thermal output available (reducing frequency scaling, throttling, fans) and set trip points that invoke them before reaching critical.

I have a script to record a weekly radio show from a Sydney radio station.I am in Brisbane.Sydney and Brisbane are both in the same time zone but Sydney(NSW) bounces around on daylight savings time and Brisbane(QLD) does not. Is there a way to specify a timezone for a specific job in the crontab file? If so what would be the format for Sydney so it follows the daylight savings time changes? Right now I will just change the cron schedule when Sydney goes on and off DST.

[URL] When I download the .iso from [URL] and used Kana CheckSum from [URL]i saw the following md5 value 143609CA5B6BB4E5D7341117FE46D0E1 but according to this page [URL]
the value should be 8790491bfa9d00f283ed9dd2d77b3906 for ubuntu-9.10-desktop-i386.iso I really don't understand why there is lot of difference in the .iso file. My instruction for those who are trying hard..
1)download the .torrent version but not the direct download if you are at indian zone
2)use Kana CheckSum from kanasolution.com to check the md5 checksum
3)Tick the "verify after write" when you burn the CD through nuro burn in windows xp

Attempting to install 10.04... I can get to the "Where are you?" screen, then the little circular "please wait" cursor spins forever and ever.
Here are a few things I've tried, with no success:Leaving it alone for hours, hoping it was just taking a really long time. No Dice. Unplugging any hardware that might be causing a problem, including the network card. No dice. Burning it to CD, DVD, and booting from a USB key. No dice. Trying every combination of kernel options I could find in the forums, and setting most combinations found in the "more options" menu in the boot screen. No dice. Booting into the live environment, then installing from there (instead of just choosing "install" directly). No Dice. Booting both from the 32-bit and 64-bit ISOs (my machine is 64-bit)
Note: I have not tried just upgrading from my 9.10 install, and I will not try this. If I can't get a live CD to boot, there's no way I would voluntarily hose my current system by upgrading.
Also note: I checked the MD5 of the ISO, and did the "check the disk for defects" menu option as well. Everything checks out fine.

I frequently travel between San Diego and Boston. I am able to add "Locations" to Gnome's Clock applet, which seems like it should take care of time zone information (see attached screenshot). However, I can't figure out how to set one (or the other) as my current location so that it will update my time zone information.

The thing is, I've created a new local zone here (called "local.lan"), and, aparently, it is working fine, and DHCP3-SERVER is updating DNS info through the controls.But sometimes I get some strange answers from the server, like when I do the "arp" command in one of the clients, and get the server's hostname "mixed" with it's own reverse, like this: "dns.local.lan.2.168. | ether | 00:02:1e:f5:61:74 | C | eth0". Other thing is that sometimes my DNS don't update when a computer "enters" the lan. In the /var/log/syslog the DHCPOFFER appears, but the information about the DNS update isn't there.So, I would like to show you my named.conf file and my local zone db file, and get some feedback from you (what would you change... what is wrong...).
