Im trying to learn BIND DNS! (yes im bored) Running Ubuntu Server 10.04 LTS.
What files to edit.
1) I want to add a A record for a machine
2) I want to forward none-discoverable lookups to another DNS server.
I found on google seems a bit harsh for me to understand.
p, li { white-space: pre-wrap; } Laptop connects to a (wired) ethernet port on a DLINK DIR-625 wireless router using dhcp. All works perfectly.
Using the same laptop connecting to the same wireless router, but using the wireless adapter and dhcp instead of wired ethernet, I can ping IP addresses on the LAN and also WAN IP's to/from anywhere on the net. I can perform reverse name resolutions (ip to host name), but not forward lookups (host names to ip addresses). I can use the DNS server obtained from dhcp or specify, by ip address, a DNS server to perform the lookups. This makes no difference.
Web pages (LAN server pages or from the internet) are not accessible by site address name or by ip address specifically.

Removed the thread; figured out that this does work in the zones config:

I've gotten everything working on this laptop but bluetooth on a 10.10 setup. I know that the system detects that there is an internal bluetooth adapter but isn't correctly configuring or using it. Here is some background, the dm1z comes with an Ralink wifi / Motorola BC8 3.0+ Adapter for bluetooth. This combo wasn't detected by the system on fresh install but I've managed to confgure the wifi driver but the bluetooth is another thing. The problem I have with the dm1z internal bluetooth is not turning on the bluetooth but discovering something. Here is some feedback from the bluez stack.
Code:
$ hciconfig -a
hci0: Type: BR/EDR Bus: USB
BD Address: 90:00:4E:A4:63:EC ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:1579 acl:0 sco:0 events:45 errors:0
[Code]....
Which leads me to believe that the bluez stack can't configure the combo wifi/bluetooth driver.
My kind isp had set up a authoratitive dns server that can't be cancelled that points to the wrong ip address. Hence I need to take all the traffic going into server A at the ip address aa.aa.aa.aa and send it all onto server B at ip address bb.bb.bb.bb. After much head scratching, I managed to achieve it as follows:- On the server at ip address A, set up following :-
iptables -t nat -A PREROUTING -d aa.aa.aa.aa -j DNAT --to bb.bb.bb.bb
iptables -t nat -A POSTROUTING -d bb.bb.bb.bb -j MASQUERADE
I have an apache2 server on a Debian box that I am using as the reverse proxy for my sites that are sitting behind it and everyone is happy. But now I want to be able to access my vmware server console from outside the network without exposing the vmware server port to the internet. So I did this I created a new virtual host for apache and it looks like this (edited for the real world)
Code:
<VirtualHost *:80>
ServerName server.my.domain
# RewriteLog "/var/log/apache2/rewrite.log"
# RewriteLogLevel 9
[Code]....
So here is what I want to be able to do. I want to be able to punch in [URL] and have the reverse proxy just take care of everything else without having to punch in the port number or anything else. I'd also like to have if possible the ssl on the vmware box just pass through the proxy back to the end user. If that isn't possible and I need to create a new ssl for the apache box then that is ok too. I have googled this and looked at several other sites but I'm still a little bit lost.
i have a web site and i need to forward all requests to the same page. Basically i would like to show a maintenance page while we are working with our database behind the application and in the meantime i would like to redirect all url in the root directory as following :
http:[url].....
http:[url]....
i tried to perform the action using mod_rewrite in this manner :
Code:
RewriteEngine On
RewriteRule . http://www.mysite.com [L][code].....
The webpage at http:[url]....has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.
I am using Squid Proxy Server alongwith Dansguardian, dhcp3 and ClamAV on my local network. Everything is working fine except for .flv files like [URL]. The problem is that Squid wants to download the whole .flv file first to its cache and then serve it to the client.
It has an advantage that the whole video loads at once on the client's browser but that is not what our users want.
What they want is that these files load on the fly as they do on a normal internet connection. How do I configure squid to serve .flv files on the fly to the client PCs?
I have linux server setup on a network with 2 interfaces. One (eth0) is connected to the regular network and the other (eth1) has a DHCP server and transparent web cache listening on it. The machines connected on the eth1 side are on a different subnet and the linux server is there gateway. Untrusted machines are introduced to this network to keep them isolated.
This isolation works well, too well. There are a small set of resources on the regular network I would like to make available to machines on untrustworthy network. I think I need to use iptables but alas I've had no luck in piecing together the command I need (in one case looking myself out and having to physically reset the machine).
I am not a complete GNU/Linux newbie, each day I discover how little I know of this wonderful OS. The title of this post is actually a question for which I already have an answer, however, I can't seem to figure out why this happens. In order to enable ip_forwarding, I always enable it the same way, by issuing an:
#echo "1" > /proc/sys/net/ipv4/ipv4_forwarding.
I don't enable forwarding at boot time on purpose, I prefer to do it manually if the server crashes.
The thing is, I always write rules for iptables in order to enable it to NAT my packages through the router. However, last night, I forgot to load the proper iptables script, and instead, used a script I am currently tweaking. In this script, no rules are listed for both the forward chain and nat table in the POSTROUTING chain. Since forwarding was working (to my surprise, I might add) this could only mean, that the kernel default forwarding policies include masquerading. Is there a way to verify this?
my server runs fedora 12 i686 LXDE and has an 80 gig hd.on ftp i have a high volume of files that do not fit on the 80 gig hd, however if i could somehow connect to a lan fileserver on the lan and make it accessible through the server, all my problem would be solved. how do i do this?the reason i dont attach more HD's to the server is that all my hard drives are sata and the server doesnt support this
View 11 Replies View RelatedI have a server on my router on the DMZ. All outside traffic goes to it. This server has Apache running and the domain mysite.com resolves to the the DMZ web server. I have a second server on the LAN that also has apache running. I want to set up another domain, myothersite.com to resolve to the second server on the LAN. Since the main server is on DMZ I have the DNS A records for myothersite.com pointing to the public IP that the DMZ is on.
How do I get myothersite.com to resolve to the second webserver on the LAN? What configuration do I need to do on my DMZ server so it routes traffic for myothersite.com to the other server on teh LAN? Do I use BIND DNS? If so please advise on how to set that up. BIND DNS seems confusing and I having trouble knowing how to configuring it. Is there another option besides BIND?

View 3 Replies View RelatedI'm running Ubuntu 11.04 and I'm really new to linux. My problem is that whenever I try to browse a site I notice the website loads very slowly because it takes a long time to do lookups. I installed Ubuntu with an onboard NIC and later switched to a PCI NIC (Dlink DGE-530T). Although I disabled the onboard NIC in the BIOS, it doesn't help. Could this conflict in configuration be a problem? My download rates are fine, its just lookups that take really long ( upto ~ 10 seconds). I know the PCI network card is fine because when I jump to Windows 7, lookups are normal again (~ 300ms). At first I thought about installing the sk98lin drivers for the PCI NIC but I saw a couple of places where people have mentioned that the skge driver that comes along with the kernel is better.
I have tried a system wide as well as Firefox disable of IPv6. Here is my /etc/udev/rules.d/70-persistent-net.rules
Code:
# PCI device 0x1186:0x4b01 (skge)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:01:14:eb:39", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x10de:0x0373 (forcedeth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:3e:19:ed", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
The interface I want to use according to the listing above is the one with the MAC - 00:24:01:14:eb:39.
I tried removing one of the entries in the file above and rebooting but it still didn't work. Here is a look at my /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static

way to get nginx to perform DNS lookups at regular intervals against hostnames that are defined for upstream servers? It seems nginx only performs a DNS lookup once, the first time it starts, and subsequently does not perform any other DNS lookups. This causes problems when the ip addresses of our upstream servers change.
I posted this same question in the nginx forum; however I also posted it here as it seems that not many of the posts there get answered.

I have an odd issue with postfix 2.5.5 trying to relay email internally to a range of mail servers and it keeps ignoring the transport map [ ] and instead always doing mx lookups.
Essentially the server is only allowing connections from an internal network and only for certain domains that it will relay to other mail servers.
It has no local delivery and yet every time I get email passed to it, it will check the local network DNS server for MX information or with diable_dns_lookups enabled (as below) the A record for the domain, and try to deliver to that instead of the transport map destination.
Here's the main.cf
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
disable_dns_lookups = yes
# appending .domain is the MUA's job.

I'm running some vm's in FC12 with kvm-qemu and using virt machine manager. I'd like to have some ports automatically forward on startup and be able to add redirections on the fly. Redirection on the fly is talked about here, but I am getting lost on what should be basic instructions.[URL]
As far as startup, In the past I just ran qemu from the cli and manually specified redirection with redir. I can't figure out how to do it with The virt machine manager which I am using to start my VM's now. I do not want the guests to see the host. From cli startup without virt machine manager, it looked like this: qemu -m 256 -hda vm.img -redir tcp:5555::80 -redir tcp:5556::445 &
We have bind 9.3 running on CentOS 5.2. We are able to do reverse lookups for the public IP's but not able to resolve to the private IP's on our network.

View 5 Replies View RelatedNow I know how to set up port forwarding on a router so this is not that. What I want to do is, if possible, connect from Computer A to computer B and use computer B as a proxy for all of the Transmission (bit torrent) connections. I know how to do this with DNS, Http, etc etc but I'm not quite sure how to go at this with torrenting.Note that in this case Computer B is a ubuntu 10.04 server with an SSH server but no torrenting program installed.
View 1 Replies View RelatedI need to be able to do the following: Physical Router located at 192.168.40.1
On Ubuntu 10.04 Lucid machine:
eth0 with static ip 192.168.40.2
eth1 with static ip 192.168.40.3
eth2 with static ip 192.168.40.4
Associate a virtual address to eth1 with an entirely different network address such as 192.168.50.1 Do the same (virtual address) for eth2 -- e.g. 192.168.60.1 In the application:
register phone number A at 192.168.40.1 (The application will automatically use eth0 for this)
register phone number B at 192.168.50.1
register phone number C at 192.168.60.1
Somehow forward all traffic (including the register request) sent to 192.168.50.1 to 192.168.40.1 as if the register had been made directly to 192.168.40.1. In other words, the app "sends" registration and traffic to 192.168.50.1 but then Ubuntu forwards it to 192.168.40.1 (but the app does not know that). Similarly, forward all traffic sent to 192.168.60.1 to the router at 192.168.40.1.
Do the same for the reverse, forward all traffic that the router sends back to 192.168.40.3 (eth1) to 192.168.50.1 (within the Ubuntu machine) so that the app knows it is for phone B. Similarly forward all traffic that the router sends back to 192.168.40.4 (eth2) to 192.168.60.1 so that the app knows it is for phone C. Thus, the application believes that it is registering at 3 completely separate routers on 3 completely separate networks via 3 separate network interfaces but in fact is really registering all three to the same router (but does not know that). Similarly, the router believes that it is receiving 3 separate registrations because it receives each registration request and traffic from 3 separate interfaces and thus 3 separate mac addresses (i.e., of eth0, eth1, and eth2). Traffic sent to and from the router for each of the 3 phone numbers (via eth0, eth1, and eth2) are not mixed because the translation happens in both directions.
For some reason in the 10.10 installer (I'm on a liveusb right now) I can't move forward. I'm in the Who are You? section. It just says "ready when you are" at the bottom though I can't move forward. I've typed in all the fields, what's wrong?I tried going back a few times and going forward but that doesn't help.
View 9 Replies View RelatedI set up debtorrent on all my machines on my LAN, which is a varied mix of machines, including one Karmic, one Lucid, and a Debian Squeeze. These are behind a NAT-based firewall. I'm not sure if I'm getting any benefits from the bittorrent peer-to-peer features because I am not forwarding any ports.
Does anyone have a similar configuration? How does one deal with debtorrent on multiple machines? Does it really help if ports are forwarded? If forwarding helps, does one need to segment the forwarded ports for each different machine?
