Server :: External Machines Can See SOME Subdomains But Not All?
Sep 16, 2010
I have a DNS server on my LAN at 192.168.140.25. Going by the example in the O'Reilly DNS and BIND book I bought, I set up the domain movie.edu and [URL]. To my great surprise and delight, I can access toystory.movie.edu in a browser from another PC on the LAN (as long as I add 192.168.140.25 to the DNS servers). Encouraged by this victory, I decided to try to set up another subdomain at [URL].
This kind of worked but not completely. Interestingly, I can get to both [URL] and [URL] on my server, but on my PC, I can only get to [URL] not [URL]. Here is my db.movie.edu:
Code:
$TTL 3h
movie.edu. IN SOA toystory.movie.edu. al.movie.edu. (
1 ; Serial
3h ; Refresh after 3 hours

I've got a DNS problem I cannot figure out. I've been digging and pinging all day and I've waited for caches to expire and I'm not having much luck.From my desktop mac, I can't seem to resolve mail.port-o-call.net:
I have set up a dedicated server running Ubuntu Server Edition. I have apache2 installed and running great. I wish to let friends and family host their individiual websites on it, but I'm running into a bit of a dillema. It seems that my server automatically redirects them to my home page and not theirs.
I run my own DNS servers and host my own domains. I'd like to host a few subdomains of one of my domains on a server with a dynamic IP. Is there a way to do this? I *believe* that I can host one subdomain by using a CNAME record and a dynamic DNS service.
[code]....
How can I host more than one subdomain on a server with a dynamic IP address?
When I first encountered this problem, I though it would be a simple solution, but i must just be missing something obvious.i have a few name based hosts configured in apache.when i go to "www.adomainname.com" i get the first website on this list, not "adomainname.com", as i would like. Does anyone have any ideas on how to fix this?here is the relevant part of my config files:
I want to setup a mail virtualserver in apache so that a mail. subdomain whats pointed to the box will automatically goto my roundcube install. i have all of the document root stuff working, however, mail.* doesnt work for a server name.
I have Fedora 9 on an external disk, I use it at home on a desktop and at work on a laptop. It works great except that the two machines have different display adaptors. I currently have the xorg.conf arranged so that I manually comment out the driver that I am not using. It works, but I would like not to have to edit the xorg.conf every time I switch machines:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildmeister@builder63) Thu Feb 5 00:18:17 PST 2009 # Xorg configuration created by system-config-display

I have tried googleing for something but cannot arrive at a satisfactory search phrase to yield the required results. I looked at [URL] and tried multiple Device and Screen sections but could not get it to work.
I'm running a "relatively standard" home network environment. That is, I've got a DSL connection to my ISP, and am running a router/NAT environment that connects a number of machines -- Mac, Windows, and Linux -- to the external network. Internally, all the machines have addresses in the range of 192.168.0.x. However, because of the static/NAT address mapping, the machines whose internal addresses are mapped to external static addresses show up at external hosts as 216.xxx.yyy.zzz (the address range assigned to me by my ISP).
The other machines, which are on the network via NAT, show up as 66.xxx.yyy.zzz, the address assigned by my ISP. Finally, I'm running a local DNS server that handles addressing issues for my domains and sub-domains that are hosted on local machines. All the machines use this local server for their DNS, with my ISP's DNS server as secondary. All of this is to say that it's more or less a pretty typical configuration, and, in general, everything is working fine.
Here's where it gets tricky:
* Machine A is a Fedora 10 linux box, which hosts an externally visible domain and runs, among other things, a web server. It's assigned to one of the addresses that's mapped to a static IP address.
* Machine B is a MacBook Pro, running Snow Leopard (10.6). It typically runs at 192.168.0.6, which is NOT one of the addresses mapped to a static address, but "just" a NAT address.
Now, suppose Machine B hits the web browser run by Machine A: the log files should show the traffic arriving from the local address, 192.168.0.6. However, it instead shows up as coming from 66.xxx.yyy.zzz, the external NAT-affiliated address. This seems wrong, especially since all the other machines on my network show 192.168-type addresses when hitting the web server.
I now change Machine B's address to 192.168.0.5 -- one of the statically-mapped addresses. Browsing traffic is now arriving from 192.168.0.5, which is (I think) as it should be. I now change Machine B's address back to 192.168.0.6. The web traffic on Machine B is now reported to be arriving from 192.168.0.6 -- NOT 66.xxx.yyy.zzz. It's complicated by the fact that I don't know where to look for the problem. All the log files on all the machines seem relatively normal; there are least no glaring problems screaming out from them.
I have a rather large USB drive that I'd like to be able to use across the different machines I own. I'm having a hard time figuring out what would be the best file system to use on it to be able to read/write things from the 3 OSs I'm in contact with: Windows, Linux and Mac.
I'm rather (VERY) inexperienced when it comes to Linux, but Fedora 14 is the environment I have to use on my laptop at work, so please forgive any dumb that comes out of me.
How do I tell php to send an email with mail() using an external mail server?
The situation: I've got apache/php running a webserver on my local machine. It's for dev purposes only, and the website files I'm using are checked out from our SVN. This lets me make changes to our website while not actually changing our website.
I've come across an issue I'm fixing where I need to verify that an email is successfully getting sent out, and unfortunately, this email is sent out using php's mail(), and not our website's usual $mail object. Unfortunately, I don't have the authority to change how this sends out right now, just when it sends out.
I've been running everything fine on my machine for a month now, and haven't needed the mail stuff until now. How do I tell php to send an email using an external server?
I installed a server called Oracle VM Manager, which is actually a web based application to manage Oracle VM server.After successfully installed everything, it suppose to be access by browser using But strange thing is, I can see web pages from the server itself with but any other machines to access it with hostname or ip address all failed.
Internet <-> [public IP] Router [192.168.x.x] <-> Local Local <-> DMZ Local <-> HostB Local <-> HostC
I have a system set up as a DMZ which works great for accessing SSH and other various services. I have a dyndns account that points to my public IP and allows me to access my DMZ box from around the world. I would like to make a subdomain of my current dyndns account and point it to HostB so that it can host a webserver on it, and have another subdomain point to HostC with a separate webserver on it. each would have SSH, FTP, Etc and have to not conflict with one another behind one IP. I don't even know if it is possible, but it seems like if there is a request for dev.host.homelinux.com that packet would have to hit [URL]and could be iptable'd to be routed to the appropriate local machine somehow.
I am not using cpanel or anything, just SSH PuTTY client. my domain is [URL]now I want to craete a sub domain i.e [URL] , how will I create this ? so I can upload files to the sub domain
i was looking for a way to find out all subdomains of a domain and i have found dig.But it doesn't seam to work how i sow in those tutorials.this is what i get:
PHP Code:[code]....
Is there other way that i can find out all subdomains of a domain?
I'm doing development on a site, let's call it mysite.com. mysite.com and www.mysite.com works fine, but proxy.mysite.com and dev.mysite.com point to the LAMP stack running on my computer. Pinging mysite.com gives me:
Code: 64 bytes from server.myhost.com (64.64.0.102): icmp_req=1 ttl=47 time=47.4 ms Whereas dev.mysite.com gives me: Code: 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=1 ttl=64 time=0.031 ms Subdomains of any other site work fine. I am absolutely baffled. What in the world could be causing this? I haven't been messing around in /etc/hosts or anything like that.
I've got a home server running Ubuntu Server 9.04 and several machines running Ubuntu Desktop (9.04 and 8.04) and Windows (XP, Vista and 7). Now what I want to do is to create a domain and directory server similar in function to Windows Server w/ AD and join my other machines to the domain, but am not sure where to start. I already have file shares with Samba but now I want to setup a domain.
I only have one IP adress to access the server. But the server will host 3 web sites and I want them to be hosted in a vm. So, I want to setup 3 virtual machines to do it and use apache reverse proxy and vhosts to redirect the domain requested to the right vm. Now. I understand the concept, but I am not an expert to set that up....
I have an openSUSE 11.3 server. So, I have to set a virtual machine server, is that right? I have been told that I cannot do it with VMware server in oS 11.3. Can I use virtualbox for this? I only have to install virtual box? Is there a special version to install? Once the virtual machine server is install, is it trivial to create 3 vm? So, I want to know wich are the steps I have to take to set that up.
suddenly ,I get a project to shutdown all xp's by a Linux server(RHEL5) using a single command.by net command i did that.but in this case i have to specify all the ip addresses manually .Is there any way that Linux server obtain the ip addresses automatically on a network and then shut down all the pc's
I would like to setup grsync to auto backup me xp desktop and win7 laptop.I have setup samba and can access the directories on the ubuntu server.I can see the desktop and laptop on the network from the server.But when I try to find the machines i want to backup in source in grsync they are not there.What should the permissions be on the windows machines?
I am having a server in a corporate data centre. There are some virtual machines running on it.The main server is accessible from internet via SSH. There are some people who within the lan access the virtual machines whose IPs on LAN are
from internet only one host is allowed SSH. This machine has public IP and is also connected to LAN on the IP 192.168.1.50. Tunnel is not allowed on our network.So now I am came across a solution as explained on this link. I am not clear with on which machine .ssh/config file I add following
Code: Host securehost.example.com ProxyCommand ssh user1@insidemachine.com nc %h %p Should above be done on gateway where public IP and ssh is allowed or client on internet who has to login. Do I need to create separate accounts on the gateway also so that the users who can SSH to gateway then are forwarded to inside machines? Or one account on gateway is sufficient for different people logging in via internet to my gateway and then forwarded to internal machine?
Then do I need to create an account user1 on the gateway also?
1) What is the correct syntax for ProxyCommand on gateway's .ssh/config should I use
Code: ProxyCommand ssh user1@inside.machine nc %h %p or I should use Code: ProxyCommand ssh user1@gateway.com in nc %h %p
2) Should I create new user accounts on gateway also which exist on internal machine?
I'm planing to get 4 dedicated, remote servers for my start up, the question I have is: how to do only one installation and then duplicate or clone this installation into all the other machines. I could install those 4 servers manually, but the problem is - we have a lot of things that our application needs, and later there will be more servers. So an automatic way to do that would be better. We are using Debian. Perhaps there's a way to create a "big package" that will contain all of the necessary software in it, then simply require from the hosting provider that all of our servers come with Debian installed, and then manually upload the "big package" and install it?
I cant get my linux server ( centos5 ) with virtualbox run 2 virtual machines in headless mode. Only one machine gets network connection. Can anyone tell me how to make 2 or more virtual machines work with 1 eth-port in headless mode using virtualbox ?
I am trying to add subdomains on ubuntu 9.10 desktop edition and and I am not sure whether I need to add some info.(such as 127.0.0.1 sub1.example.com and so on) to the /etc/hosts file like the windows' windows/system32/drivers/etc/hosts file. I used to use the wamp-server(on Windows 7), I needed to edit 3 files, httpd.conf, httpd-vhosts.conf and hosts. And almost every edit is made in the httpd-vhosts.conf file on wamp-serveriles should be edited? or what else should be done that I didn't mention?
I am quite interested in one thing. I am trying to code my dns server that when I connect to one of my subdomains it connects not only to an ip address but to an ip : port address. For this I tried using SRV record, but with lack of success.
Dns server specification: OS Ubuntu server 10.10 and using bind9 I have configured everything so that my subdomains work on an ip address, but I need some of them to work on ip : port too. In my brfconcept.lv.db file i used: (what I mentioned below isn't the full content of the file)
Code: _http._udp IN SRV 0 5 27017 testing.brfconcept.lv testing IN A 83.99.211.134 in my rev.0.168.192.in-addr.arpa i used: (what I mentioned below isn't the full content of the file) Code: 134 IN PTR testing.brfconcept.lv
What I would want is not just for 1 service to aim at at the 27017 port but all services if its possible, when you enter testing.brfconcept.lv Is that possible and what am I doing wrong?
I used to use server 64, and it handled memory well with Jaunty and Karmic but with Lucid the memory usage is always high and can't run virtual machines.
I have developed a website. Now i would like to monitor the IP address of machines who are accessing the server. The simplest possible solution to this that comes first into my mind is to use jsp inbuilt tags.
I am currently investigating channel bonding for rhel5.5.Is there any way I can create one bond from nics on two different linux machines.They will be a cluster without any clustering software like beowulf or LVS.There will be a cluster interconnect through which they can communicate.Should I tweak the bonding module??
