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.
View 2 RepliesI'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.
View 3 Replies View RelatedAt 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 am working on Red Hat Linux since last six months and learning it steps by steps. like configurating ftp server,NSF ,DNS and then email server. I want to learn squid server but technically before going into it what you suggest me that may I first learn to configure Linux as a router,Firewall machine or do IP masquerading on a server. Because all these things are directly or indirectly involve in squid.So guide me because going to start squid i may understand Linux IP table ,how to add entries in it,how to delete entries ,I think you understand my point which i want to ask for guidence.
View 4 Replies View RelatedSo I have some entries like the ones below. I have a system setup to do all the routing/dhcp/dns. This is a private network for education purposes only, and I have no idea how half of these addresses got in the arp table.
shell>arp -n
192.58.128.30 (incomplete) eth0
192.228.79.201 (incomplete) eth0
192.36.148.17 (incomplete) eth0
[Code].....
how to just clear the table. That's all I want. Is that too much to ask? I also noticed in Wireshark that packets are constantly being sent to find the MAC address that these IPs belong too. I really want that to stop happening.
EDIT: I have also tried using ip neighbor. I ran "ip neighbor del 192.58.128.30 dev eth0", and it gave no errors but didn't remove the entry. All the ones without a MAC are also listed as FAILED in ip neighbor.
Here is what I tried:
Since I had no aliase in /etc/modprobe.d/, I made one. I have also added entries to blacklist.conf ( even tried blacklist with out the .conf ), added entry to sysctl.conf, and added a no load to my grub.conf ( /etc/default/grub). I am still seeing ipv6 in netstat but not when I check lsmod. Below are my entries:
Code:
cat /etc/sysctl.conf | grep ipv6
#net.ipv6.conf.all.forwarding=1
net.ipv6.conf.all.accept_redirects = 0
net.ipv6.conf.all.accept_source_route = 0
net.ipv6.conf.all.disable_ipv6 = 1
Code:
cat /etc/modprobe.d/blacklist
blacklist ipv6
install ipv6 /bin/true
Code:
cat /etc/modprobe.d/blacklist.conf | grep ipv6
blacklist ipv6
install ipv6 /bin/true
Code:
lsmod | grep ipv6
#
Code:
cat /etc/default/grub | grep DEFAULT
GRUB_DEFAULT=0
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet splash"
Any ideas why I am still seeing service listing with ipv6?

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...

View 3 Replies View RelatedAt 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.
View 2 Replies View Relatedi 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.

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.
Domain name which is registered on the DNS for an IP and the name of the host with that IP need not be the same. am i right? I mean domain name and host name need not be the same. Is this correct?

Using my own domain w/ LAMP
View 3 Replies View RelatedI have my home server set up as an ftp server, LAMP server, ssh server, all that fun stuff. I usually access it externally using my IP address, but I would like to get a domain name for convenience reasons. I wonder If you could recommend a site that will register a domain name for your IP, preferably for free. Or would I be able to do it myself by installing a DNS server on my server? I'm not really sure how that works. I'm pretty sure that you can only do that with local servers, right?
