Networking :: Domain Won't Load From Local Network?
Feb 15, 2011
Have a domain registered on a public ip. The domain server for the domain is on the same local network as the web server that uses the domain. The web server naturally has a local and public ip address.
The problem is that whenever I try to access the domain from my local network the lookup for the domain fails, as it cannot find the server from the local network. What's the most painless solution to this problem?
TL;DR: need for my domain to be accessible from both my local network and the outside world, now it's only from the outside which is a problem.

I am currently working on a project related to packet sniffing which has been implemented using the concept of raw sockets. I am using C language.I am able to decode the following details from the packets received from a local network,like:
source and Destination Mac Address
source and Destination IP Address
source and Destination port no
But I am having trouble in decoding the domain name when an user in the local network is logging onto internet.For eg. if a user in the local network is trying to log on to web using his browser say if he has logged on to url then from the packet I need to get the following details
source Mac Address from which user had logged on
source IP Address from which user had logged on
domain name

I dual boot windows xp and ubuntu 10.04 LTS and the wireless card works perfectly fine in xp so I know its not a hardware/network issue. In ubuntu, it detects wireless networks, will connect to network and work for about 20 seconds.
[Code]....
and it continues on after this alternating between a normal 20ms and high ping over 200ms. The connection refuses to load anything off the internet/local network.

I'm trying to set up a *simple* MTA in my local network. The only thing it should be able to do is send system / daemon mails to admin@mylocaldomain. but at the moment I'm pretty much overwhelmed by everything i *should* know in order to set up this MTA
my infrastructure:
- servers:
* test01.mylocaldomain --> should send mails (with exim) to admin@mylocaldomain
* dns01.mylocaldomain --> dns-server
* mail.mylocaldomain --> mail-server (postfix / iredmail package)
I configured exim to be in "internet"-mode. now i have a variety of errors I can choose from (and a variety of solutions that i don't like ).. my test is always an email from test01.mylocaldomain:
echo "Hello World" | mail -s Testmail admin@mylocaldomain
- after running the config, i get the error: admin@mylocaldomain: all relevant MX records point to non-existent hosts --> google says, edit and udpate update-exim4.conf.conf --> dc_relay_domains='mylocaldomain' --> but this exim installation should not be a relay at all. it should only be able to SEND (to this domain), not deliver it. or do i get something wrong?
- after i added dc_relay_domains='mylocaldomain', i get --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 550 5.1.1 <root@mylocaldomain>: Sender address rejected: User unknown in virtual mailbox table --> but i don't want to create an account on the mailserver for the SENDER...
- ...so i thought, i'd config exim with the domain "test01.mylocaldomain" (including the server name), so that the sender is clearly from another domain than the mail server handles (e.g. user@test01.mylocaldomain).. but then i get this --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 450 4.1.8 <root@test01.mylocaldomain>: Sender address rejected: Domain not found
I really just wanna send mails in my local network.

I have public IP and registered domain mydomain.eu. On domain provider DNS servers, mydomain.eu points to my machine called solis (10.10.10.1; this is gateway, dhcp and dns server; eth0 is outsite, eth1 inside my network). I have also laptop which is connected to eth1 through wireless AP. From laptop and solis I have access to outside and inside network without problems. Of course my dream is to have access to solis from local network using name 'mydomain.eu' but not fully name 'solis.mydomain.eu'.

ever since upgrading from karmic to lucid, i cannot ping fqdn hosts in .local tlds. nslookup & dig work, but most other utilities fail (ping, traceroute, etc...). i know .local is an invalid tld, but apple seems to have made it a defacto standard on private networks, so i'd imagine somebody else has seen this issue before... is there a simple fix that doesn't require managing hosts file entries on a bunch of systems?

I recently installed bind9 on mandriva 2008.1, after having done the necessary configuration.. I still can't find my domain I configured cant ping on other machines on the LAN but can actually ping on any other website on the internet even though name server is configured to point to local machine..... I dont understand what I'm doing wrong.

I want to use single label host names on my local LAN, without using any domain (at least no registered one). My machines should be named in a fashion similar to 'myserver', 'mydesktop' etc. so that i from a browser on any LAN machine may write 'http://myserver', and get the webserver on 'myserver' (so NO domain part, e.g. myserver.domain).
Do i need to create a DNS zone for each host or is there a way to put all host in a single zone, if so; which? Would such a name be considered a root domain?

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

I have an internal domain (dev.lan) for which my Ubuntu server is authoritative. We have a number of subdomains under that domain (test.dev.lan, svn.dev.lan, etc.). The server also acts as the primary DNS server for my office. It was originally set up under Ubuntu 8 and worked great.
However, ever since we upgraded to Ubuntu 10, our Windows clients periodically lose the ability to resolve domains on the dev.lan domain. Internal IP addresses can still be pinged from the Windows machines so it does not appear to be a network-connectivity issue. External domain names continue to resolve without any problems. The only workaround is to restart networking on the Windows clients. It's frustrating because it happens several times a day.
bind9 logs no obvious error messages.

I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.
However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.
Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?

In the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?

I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.

I have two networks. One of them is wired, the other is wireless. The wired has an internet connection and a few other computers connected to it. The wireless network has a few hosts connected to it too, but it has no internet connection. What I've been trying, fruitlessly, to do, is make all connections that are bound to the internet, or my wired network, be routed that way, and all the connections to the hosts of the wireless network go that way.
Here's the setup..
Wired:
192.168.1.0/24 Gateway = 192.168.1.1
Route internet through here
Wireless
192.168.2.0/24 Gateway = 192.168.2.1
If my computer sends a packet to the internet, it should be routed through 192.168.1.1 If I send a packet to one of the local hosts of the wireless network, it should be routed through 192.168.2.1. Here's the routing table I've set up(This is one of many configurations I've tried)
Code:
$ ip route show
192.168.2.1 dev wlan0 scope link
192.168.2.0/24 via 192.168.2.1 dev wlan0 src 192.168.2.4
[code]....
With this, and everything else, I get destination host unreachable when pinging. The strange thing is that, if I unplug my eth cable, reboot and connect to the wireless network, everything is fine and I can access the router and the others. I'm trying to improve my networking skills, as I've had this of setting up a small linux box as a router for quite some time, for the fun of it, but I need to get routing under control before I go ruin my network.

I was wondering if there is any way to enable an MS Windows client that is otherwise unable of joining a domain to join a domain controlled by (open)SUSE? Is that inability only for joining a Windows based domain but a client that runs XP Home Edition or similar domain- incapable version of Windows could join a domain if it was controlled by Linux?Pardon my newbie style, but answer doesn't have to be detailed step-by-step, just yes/no answer with some pointers would do. I am not new to linux but new to network services... search engines weren't friendly when asked this question at the search bar...

I have update my linux server from mandriva 9 to mandriva 2010
I was working using samba 2.2.8 and now I have samba 3.5.3.I have transfer all passwd and smbpasswd to new linux.I have convert smbpasswd to tdbsam
when i am using win xp to logon on samba domain the windows XP does not load profiles from samba. I think that the problem is NTUSER.DAT storing in /home/user/profile
The same profile is working using samba 2.2.8 but not working in samba 3.5.3..

I find it hard to explain but I will try. I have a small network using CentOS 5.4 with a static ip and I am running a web server which has an local ip of 10.1.10.100 and has the domain name of www.inwoon.net.My problem is I have other computers on the same network and can only access the web server using 10.1.10.100 instead of www.inwoon.net. am finding it to be impossible to test my web site work using external links that call back to my site

As it looks like the number of DNS Top Level Domains are just going to proliferate in the near future, use locally on an RFC 1918 private network in order to prevent a future name collision issue?
.local is the most obvious one but as that was stolen by Apple for mDNS/rendezvous use it's probably wise to avoid it now.

If i want to use SSH to log on to my home computer, which is connected to the router, how do I go about connecting to it?If I get my external IP of the computer at home, it will show me the external IP of the router correct? Then I need to forward the router's external IP to my computer at home. But then, how do I connect using ssh? or do I need to consider my local IP of the computer at the router's network?

Let me start off by saying everything WAS working...I have a lab environment comprised of two subnets (.1.128/25 and .2.0/25). On the .1, I have 3 Solaris 8 servers running NIS, NFS, databases, DNS, various services, etc... the network was setup on VLAN'd Layer 3 switches with the VLAN interface addresses acting as default gateways (dgw) for the two networks (on a single switch). The switch dgw was a router for outside connectivity. The servers are running ODCS OpenSSH.I was having problems with the VLANs, so I reconfigured the network so that each subnet had it's own switch as a dgw, and they route through a point-to-point static route setup as 192.168.0.1&2 on a separate VLAN between the two gateway switches.Here's where the problems start:First, ALL the services (NIS,NFS,databases,DNS,etc) are STILL WORKING. I can ping all the addresses. Traceroutes show the proper path thru the point-to-point, etc. There are NO firewalls setup, hardware or software, network or host-based... no iptables running, etc.
The three servers are on the .1 network. I can ssh to them from hosts on the .2 network no problem. However, I cannot complete an ssh login to them from any host on the .1 network. I get a password prompt, enter the pwd, and then it hangs until I receive a "Connection timed out" error message several minutes later. The next time I log in however, it shows "Last successful login" from the failed attempt.While the connection is hung, netstat on the server shows "ESTABLISHED" to the client on the proper port. nother odd indication is that I CAN sftp to the servers from hosts on the .1 network.

In Windows XP I used to do it by editing the "hosts" file from the following directory

Running Ubuntu 9.10. In the Remote Desktop config dialog I get: "Your desktop is only reachable over the local network. Others can access your computer using the address 127.0.0.1 or tabatha.local." I understand this means only the loopback ip address is available. All my other machines show their true local ip address (e.g., 192.168.1.104) in this dialog. Thus I cannot log on to this desktop from other machines.
When I try to do a remote logon from another Ubuntu 9.10 box (or from an XP box using a VNC viewer), I get: "Connection to 192.168.1.102 has been closed." What steps are needed to make this machine show its actual ip address? All file sharing between the various machines is working properly and all windows shares back and forth between XP and 'nix, and among the the vaious XP boxes and linux boxes are available as designed.

up until about four days ago connecting to the local LAN was as simple as booting Ubuntu, and letting nm-applet automatically connect on Auto Eth0 But the other day it just randomly stopped working, with no cause that I can think of. I can still connect to the internet (This is via a PPPOE connection, running through the same wired interface) so it can't be a hardware problem with the ethernet port/cables themselves. nm-applet just stays spinning in circles, and nothing ever happens. I tried deleting the auto Eth0 entry, and creating another LAN entry with exactly the same settings, but I still get the same problems. way to completely restore nm-applet settings? Or some other way to give me access to the local network?

I've been having strange local network behavior with my Ubuntu 10.04 box. First off DNS was pretty flakey, but I replaced the automated DHCP servers with 8.8.8.8 and 4.4.4.4. Now I see very strange behavior in my local network, the symptoms of which are frequent dropped connections trying to use FTP, VNC, or Samba to try and connect to my other machines. I did a tracepath and got this back:
tracepath 192.168.1.136
1: 192.168.1.105 (192.168.1.105) 0.112ms pmtu 1500

2: no reply
3: no reply
3: 192.168.1.105 (192.168.1.105) 3002.961ms !H
Resume: pmtu 1500
