Networking :: Domain Name Resolves To Wrong Ip From Lan?
Nov 12, 2010
I have a peculular routing problem on my hands. I have a server running in my office. it has various services running on it (httpd sshd etc.) in order to access these services I have a domain name pointing to my IP.If I try to connect to the server from an external IP, all is fine and working as normal.However, if I am connecting from the interal lan to the server, my domain name resolves to the address of the routerSo for instance everywhere on the interent my domain name resolves to the correct external IP (12.23.34.45) which is then connecting through my cable modem (12.23.34.45) to my router (192.168.55.66) and directed to my server (80.80.80.80)however if I resolve my domain from within my lan, I get my routers ip 192.168.55.66 so trying to connect to my server times out while connection to the wrong device.My network setup is very simple. nothing fancy.I think I'm using google's 8.8.8.8 for my dns server

For example, given the range:172.128.0.0 - 172.191.255.255I need to find some domain that resolves to an IP-adress within the range. Is it possible ? I'm using a Linux system.

I have a Suse 11.2 machine named "susepc" on a network with some other windows machines. From the Suse 11.2 machine, I try ping winpchere winpc is the name of a windows machine on the LAN but the name resolves to an odd ip address:PING winpc.HOMENET (72.215.225.9)he "HOMENET" is the correct name of the windows workgroup, but the ip address is completely wrong. My LAN is based on 10.20.x.x and the winpc ip address should be 10.20.0.100. I can "ping 10.20.0.100" and it works correctly.Some things:- DHCP server is on the router- pinging from winpc to susepc works perfectly ("ping susepc" resolves to the correct IP address 10.20.0.101 and the pings respond)- "net view" on winpc lists the susepc - SAMBA is installed on susepc- the Netbios name is set to susepc- I have a shared folder on susepc that I can see, create files in, etc. on winpc with no problems.- IPV6 is disabled on susepc- I have tried setting up susepc as a WINS server (Wins Support)
- I have tried setting up susepc as a Local Network Browser

Im running a Samba server as a PDC
Every thing works fine When I log in it creates a folder on the server for the user. when the user logs out, it is copying the user data to the server, for example folders like Documents,Favorites and so on.
My problem is,Im using a Dutch version of Windows 7 but the folders sync are English

I just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being user@mydomain.biz it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my main.cf. I am running ubuntu 9.10.# See /usr/share/postfix/main.cf.dist for a commented, more complete version# Debian specific: Specifying a file name will cause the first# line of that file to be used as the name. The Debian default

I see when going to websites in firefox that they resolve to 1.0.0.0 on port 80. I added the ISP's nameserver to /etc/resolv.conf as below. Also configured my router to give the client;s the ISP's DNS server, but it's intermittent.. Some pages load, then when refreshing some time later, they fail again.
cat /etc/resolv.conf

nameserver 203.0.178.191

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.

At the school i work in i have a server2k3 server that provides a domain to all the windows clients, aswell as a fedora server that acts as an imaging machine and webserver.
Im rather concious of the fact that if for any reason the Server2k3 server was to die there is no backup of active directory, or anything that can take its place whilst a replacement is found.
So is it possible to use a fedora machine with samba as a secondary domain controller? so it can be used as a login server, and has a copy of AD.

I have a home server running Ubuntu Server 10.10, it is running Samba for file sharing with a mix of Windows and Linux boxes in my house. My main problem is that the server is only accessible by IP or by using hostname.local, but it is not possible to connect to it by just typing the hostname. Further more, it is not being automatically discovered and listed by Windows or Linux clients.
What's really odd is that I also have an Ubuntu Desktop 10.10 install on a separate computer, and that computer is accessible using just the hostname and is automatically being discovered and listed by other computers.
What is missing on the server? What is responsible for resolving just hostname, avahi seems to only deal with hostname.local and that is working fine. I also compared the samba config of the desktop and server Ubuntu installs but wasn't able to find any setting that would be influencing this. Is there some package I'm missing on the server?

This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

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 registered two domain names that i want to use to connect to my ubuntu server. I was wondering how to do this i was looking at bind9 but that didn't work that great. The server is behind a router with firewall i can connect to it using the external IP address but i like to use the two domain names if that is possible.

At work, we run Windows... Windows domain, windows workstations, etc. Today my boss asked me my thoughts on running an Ubuntu lab within the mixture of our existing Windows setup.
Well, that brought several questions to mind. So I understand you can bind an Ubuntu computer to a Windows domain, seems easy enough, whether you do it through Samba or the other guide I read that I kind of forget at the moment, but anyway...
I was just curious how Ubuntu interacts with domain users when on the windows domain. For example, if we have an Ubuntu machine on the Windows domain with a local user "administrator" and that's it, would any domain users be able to log into the Ubuntu work station, similar to how it is on Windows?

I want to host 5 websites on my new virtual server so I have created 2 nameservers that point to my virtual server's IP addresses as a glue record. What confuses me is when I create a new domain on my server it gives the new domain it's own nameservers (ns1.thenewdomain.co.uk etc) do I need to change these records so they use the nameservers I created earlier? If I do? Which particular records should I change? I'm running a Unix virtual server with a Plesk control panel.

i need to allow window domain controller user to use file share of linux.windows DC user can see the share file and directories of linux file server but not able to access.
below is brief--
I have a Linux machine which is on my network but not on my domain. I have configured SAMBA FILESERVER for file sharing purpose. I have a Windows XP PC which is on the domain(windows server) that I am trying to connect to a share on the Linux box. I supply my credentials but regardless of which login I use I always get Logon Failure. I have created an account on the Linux machine with the same user name and password as my domain account but so far no luck. Can I connect from a domain PC to a non-domain Linux box? Is there something else I should be checking?

I'm working for a smallish non-profit that has gone through some recent growing pains. We have two sites that are currently without a domain controller, and no money for MS licenses, so I was thinking of trying to add a couple of additional Linux machines (we already run Linux for web services internally, and I've set up a test case previously to see if I could get a server to join the domain, which was a success) and was trying to find out if I can get them to act as Domain Controllers without replacing the domain. The main issue that I'm having at those locations is drive mappings are not happening correctly against our DFS file servers. The one other location that had this issue had it go away when we added a local DC. The domain is a Server 2008 domain.

Is there a way to know the dns entries of a certain domain? Let's say I want to know its IN A records on their DNS Server. I know you can find the MX Record using the host command but I want to know the other IN A records associated with the specific domain.

I realize this is not a Linux specific question, but I figure Linux admins have a better understanding of networking in general. I assume this is a very basic/beginner question, but it has been puzzling me for a little while. Here goes: If I register a new domain (let's mydomain123.com) and I want to use my own DNS server. After registering the domain name, at the registrar, I want to set my DNS servers to be:
[URL]
My question is, how does the registrar (or root name servers) know what the ip address of ns1.mydomain123.com is? I will obviously set the IP address on my dns servers. At first glance, I would think this is impossible, since ns1 is just a record inside the specific domain that it is authoritative for. However, I have seen several examples companies who have a setup exactly like this.

I have a domain and the settings for it are pointed at my IP address. But when I look up my IP address, it does not show my domain as the hostname. What settings do I have to change to make my IP translate into my domain as the hostname?
