Ubuntu Networking :: Internal DNS Server With BIND ?
Aug 29, 2010
Basically, i want to be able to type a domain in my browser e.g. default.dev and it direct to the ../www/default folder on the Ubuntu Server on my network. The reason being is that as a web developer i have a number of sites that i'm working on locally and i'm getting tired of adding the domain to my hosts file and then creating a virtual host in Apache - i believe this can be done with BIND - is this right? If so what steps are required?

I have an RHEL5 server running BIND. I'd like to be able to resolve internal, non-FQDN names such as "wiki" for the company internal wiki. in my named.conf file...Named-checkzone returns no errors, and nslookup works when specifying the server explicitly, but no browser resolves the name when entered in the address line. I know this by no means a standard use of BIND, but I'm sure someone out there's pulled this off. I did see when googling someone suggest "load the root zone (.) as master, and add your "hosts" as TLDs, using CNAMEs", but tried that and probably did it wrong since it didn't work.

I have two DNS servers, one local and one remote, and I am trying to get them to talk to each other using views.
The problem I'm having is that the remote server can talk to the local one and receive zone files, but if I update the local server internal view, the remote doesn't receive the update. Here is my config:
Quote:
key "external" {
algorithm hmac-md5;
secret "xxxxx";
};
controls {
inet 127.0.0.1 allow { localhost; };
[Code]....

I have a few external IP's assigned to me by my ISP. I have IPcop as my router/firewall. I am wondering how to bind 1 of my external ip's to my internal ip address. So I do not have to port forward, etc. For Example, 77.77.77.77 to 192.168.1.123 and on the server it see's the external IP address.

There's this domain, that is apparently a cname of a cname which is, I know, not recommended, but it's not forbidden by the rfc. The domain is [URL]. If I try with windows or bind dns I get this results in nslookup:
** server can't find [URL]: NXDOMAIN
but if I try with opendns I have some results.
> [URL]
Server:208.67.222.222
Address:208.67.222.222#53
Non-authoritative answer:
www.groenegordel.becanonical name = www.vlaamsbrabant.be.
www.vlaamsbrabant.becanonical name = waf.vlaamsbrabant.be.
Name:waf.vlaamsbrabant.be
Address: 193.53.37.42
With this I see it's a [URL] it's a cname or a cname. Is there a way to force bind to resolve this domain? Is this a limitation of bind?

- winxp sp3 accpac, xen-nic2 - 192.168.0.2
- win2000 sp4, xen-nic2 - 192.168.0.200
Config: I need a dns server with:

ip: (same as above)
netmask: 255.255.255.0

dns: 192.168.0.129
ldap all machine to zimbra.mycat.kgn for login info and password.
map drive g: to samba.mycat.kgn data-share (with users rights from ldap)
I tried to do this in virtualbox, but fail badly! I created 6 vm using ubuntu 804 and 910, but my dns was not getting any records with dig, so I found an howto on powerdns. But I had to use mycat.com and not mycat.kgn?
I will draw my network to be!
each machine:
ip: (sameas above)
gateway: 192.168.0.1
dns: 192.168.0.129
dns-nameserver 192.168.0.129
nameserver 192.168.0.129
and if the dns server does not find the info it forward it to the gateway 192.168.0.1

I have a registered domain that resolves (via dyndns) xxx.mydomain.com to my external facing router -easy no issues there. Behind the router I have several machines (some VMs) running webservers, mail etc... What I want to be able to do is redirect the external traffic based on xxx to the relevant internal machine and serve the content back to the external world.
I have tried using a http rewrite of xxx.mydomain.com to the relevant machine an it works fine from within my network, however externally the re-direct fails as the master DNS servers have no record of internal DNS setup in my network (obviously).
So is there anything I can do to get xxx. recognized externally? I'm only just starting to get my head around how DNS, HTTP, TCP etc all hang together. Am I barking up the wrong tree with rewrite? Should I be looking at proxys?

Basically, I have a windows 2003 server virtual machine (vmware) inside Ubuntu 9.10.
The Ubuntu machine has IFconfig:
Code: sam@sam-laptop:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:15:c5:b8:c8:8b
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:17
Why can't I ping or simply access the internal server on my ubuntu machine from a another computer on the 192.168.1.0 (slash)25 physical network? Do I need a bridge? Iptables?

i am forwarding HTTP request to a internal server, it is quiet successful but access logs donot show the ip of the external m/c. Rather it shows the ip of the machine on which i have enabled port forwarding.

We're having an issue with HTTP POST file uploads on our two Ubuntu PCs. For some reason, whenever one of our users attempts to submit a file in an HTML form, the request times out, usually with a 500 Internal Server Error message. This problem is not limited to one site, but occurs on all sites that use file uploads. Also, the problem does not appear to be with our network, as a Windows 7 PC on the same network can upload files to the same sites without any difficulties. The problem is not browser-specific; we have tested with Firefox, Epiphany, and Google Chrome and all produce the same results. The issue is relatively new, and was first observed within the last month; before this time, both machines had no problems uploading files.
Does anyone have ANY idea what could be causing this? I've tried a number of things, including rebooting the PCs, rebooting the network, disabling IPv6, etc. I'm not very experienced in Linux system administration, but I can use the terminal and am familiar with some terminal-based diagnostic tools, so if you need any additional info or want me to try something, please let me know! I've exhausted my own computer knowledge with regards to finding a solution to this problem.

I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?

I have a BIND server that I'm setting up with different views. There is another server out on the public Internet that currently handles all inquiries for this domain. I had installed the Yum packages, chroot, etc. and edited the config files by hand. When that didn't work, I erased the server and started over using Webmin to build everything for me. Same result. I want to setup and verify everything is working on this new server before I take it into production.This is in /var/log/messagesQuote:

I am still quite new to all this but I guess we were all beginners once, this forum seems very helpful.Here is my situation, I will give as much detail as I can.I have a dedicated server which is running CentOS release 5.5.Initially I had Plesk installed, but when I upgraded PHP I damaged the Plesk configuration, and so I installed Webmin instead.
All seems to be fine with this, apart from the DNS configuration / BIND server.I know this because I have one site which uses an external DNS server and this works fine (i.e I can access it from a browser). All the others don't resolve - i.e the ones I set up in Plesk.I've done a bit of investigating to see what is going on, but I'm stabbing in the dark a little.

I've been looking for a good tutorial for setting up a BIND DNS server for my local network. What I want to do is..Have BIND running on my home server receiving all DNS requests.Have certain zones (my.zone.lan) pointing to custom IP addresses (I.E. server.lan points to 192.168.{server IP})Zones that don't exist should be passed on to OpenDNS for processing.

I need a bind-server (I mean DNS server) with a SQL backend. As far as I have seen, the only viable option I have is to recompile bind9 with support for either MySQL or PostGre.
Link to this: [URL]with an additional
Code:
apt-get install libpqxx3-dev
From some tutorials I have read, I see I need to recompile it to enable its SQL support.
But when I do it that way, I won't get any security updates, won't I?
So... Is there any bind server with SQL support in the repositories ? For that I don't have to worry about security updates...

What is the fastest setup to do this? All I want is an internally authenticated webmail server that other servers can send mail to for collection of test emails. Don't need LDAP or anything fancy, just a internal LAN only webmail server. I've got Squirrelmail setup on Ubuntu Server and can't get authentication setup with Squirrelmail and every tutorial I read is way over complicated or has nothing on how to authenticate Squirrelmail with internal, system users.

I have read a lot of documentation but it is still hard to find a proper answer to my doubts.About the hostnames in a domain, how is it associate to a determinated port?
For example, when I type on the browser webmail.sparc86.net and then I get redirected to the port of 20000 of this same domain. Fine, but how does it work that it knows it should be redirected to the port 20000? From where is this information (the association webmail-port 20000) taken? The apache will manage this, right? But what about other services like ftp?Another example, If I wrote my own software listening, let's say on the port 40000 and I want to have a domain like "mystuff.sparc86.net" how would I let it be redirected to the port 40000 ?

Currently i using webmin,but it missing some important things like $variable -where $variable would be automatically replaced with added domain,and it's kind a strange since plugin for managing other dns server on webmin does that. Also i was not able to generate 100% correct all records,only partial,which make it useless since i was need to fully replace it anyway.So can someone recommend any script/tools for it?I would be even happy with combination of batch tools(which might be even best solution since then i would not need to bother with installing script). How my dns records look:
PHP Code:
$ttl 38400
@ IN SOA ns1.nameserver.com. root.localhost. (
12520521667
7200
7200
