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.
View 14 RepliesI 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'll apologize in advance for I'm sure this has been covered already, but I'm not sure of the search terms to even use to begin solving this problem. I don't know what I don't know.
I have three computers on my home network and want to reach them by their name instead of IP address since their ip is dynamically assigned. I'm using a Linksys WRT54GL router and have noticed that there exists a "DHCP Clients Table" in the router that seems to hold all the necessary information - host names and ip addresses.
How can I get my computers to use that as the lookup table to resolve the host names? And is this even an optimal way of being able to resolve local names?
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 have set up DNS server set up on my RH 5.5 system. It is working perfectly as Caching only Server but but when i tried to make it a primary server for a zone it didn't resolved. I am actually a newbie so please correct me if i am wrong somewhere. Here are my configuration files code...

resolve.conf has the DNS according to DHCP offer, from command line dig properly resolves the name, ping (e.g. google) works, telnet to domain-name on port 80 works, GET too. When using the browser with the domain-name I tells me "Server not found", tcpdump doesn't display any activity. But when I manually change the domain-name with the IP (received by command line dig) then the browser has no problem how do browsers interact with the network resources of the OS?
I have a NAS server running Debian with Dnsmasq (local DNS and DHCP service). This is working well, including fetching upstream requests from my ISP's DNS service and caching them locally. I have another PC not running Ubuntu which happily resolves DNS and non-DNS names. E.g.
Code:
ping hagrid.
ping hagrid
both work.
However, this is not the case on my Ubuntu PC. It is only able to resolve DNS names, not non-DNS names.
Code:
ping hagrid.
works but
Code:
ping hagrid
does not.
I have the standard nsswitch.conf and host.conf.
I'm confused. Why do I get a response from ping for any scrambled internet server name I type in??The only thing that is necessary is to start with "vvvvvv."(It should be triple W in this post, but I need to do this work around due to the forum rules )And it always resolved to different IPs with similar ping times.What's going on?
Code: > ping vvvvvv.q3g87uv8123907.qt1
PING vvvvvv.q3g87uv8123907.qt1 (80.156.86.78) 56(84) bytes of data.

I have three Debian systems running, along with several XP laptops, PS3 and two DirecTV systems. I use two of the three Debian systems as media servers, and the third is an older system mostly for playing around with. My home network is running fine with the following nuisance. The two newer Debian (Lenny) systems are <barney> and <mitzi>, the older is named <oscar>, running Debian Sarge 3.1. From either locally or remote login to <barney> and <mitzi> I can ssh into either of the other two systems, however when logged into <oscar> I cannot ssh by name to either of the other systems. e.g. ssh: mitzi: Temporary failure in name resolution..However, from <oscar> I can ping outside my network (e.g. ping www.google.com) with no problems.I can also ssh to the other systems via IP address, just not by name.
I've compared the /etc/ssh/ssh_config, /etc/resolv.conf, /etc/ssh/sshd_config and other files between the two systems and not seeing anything peculiar. arp, route, etc., don't show different behavior between the systems either.
before i upgrade to karmic i used to visit some local domains like freenas.local.
But after the upgrade the domains doesnt work. I can go to smb://freenas/ but in firefox / chrome or in fstab i cannot use freenas.local ...
dammit... all that typing and I hit the wrong "submit" button. *sigh*
Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
As the title suggest, I have downlaoded the latest copy of Ubuntu Server from the ubuntu website.Everything installed fine. DHCP configured ok as far as I can tell. I can ping other machines on my network (which are running Windows) and they can ping the Ubuntu machine and conenct to Apache which is running on it.If I try to ping google.com or any other domain, it gives the correct IP address but gives no response to any pings, dont telnet on port 80 (or any toher potr for that matter) on any machine on the internet. I checked the settings using ifconfig to see what DHCP had assigned, and they matched the windows machines configuration (other than the IP address obvisouly). I tried assigning a static IP, even reserving a particular IP for my NIC.
Whatever I do, i cant connect to any machine outside the network via IP or domain.I have searched everywhere and tried everything i can find on the net but still to no avail.The Windows machines are part of a domain called alcom-uk.local and run off of a Windows Small Business 2003 Server. Not sure if i need to manually setup Ubuntu to connect using a domain or anything.
I have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!
This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.
I can't update my ubuntu clock with my server. If i run the command ntpdate domain.local, it gives me this erro (no server suitable for synchronization found) if i run the command nslookup domain.local it works well and found my server

View 1 Replies View RelatedWe installed CentOS 5 at our school and are attempting to get 2 simple DNS servers online. These are simple name resolution servers for our network. We installed the needed caching nameserver packages via Yum and all seems to be well, but for some reason when the server is online, it fails to resolve DNS records except when we direct the requests to its 127.0.0.1 (localhost) interface. As for the server specs, the DNS server is running on a Virtual Machine, and the ESXi server has 2 quad-core Xeon CPU's with 48 Gigs of RAM (in short.. hardware is adequate.)
Here's more details:
When the box boots up, we can confirm that the named service is running and it resolves DNS records when we direct queries to its localhost address:
[root@ns1 ~]# dig hotbot.com @localhost
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @localhost
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55510
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 0 .....
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @66.186.176.2
;; global options: printcmd
;; connection timed out; no servers could be reached
What would cause the Named service to not answer DNS queries from the physical IP but only from it's internal IP?
A while ago I downloaded a VMWare VM for 7.10. I then upgraded it to 8.10 and it was working just fine. I just did the upgrade to 10.04 and I'm having problems with my networking. The really odd thing is that I can ping machines on my local network and out on the Internet by IP address but it will not resolve names using DNS.
I've got the network set up for DHCP. I also tried DHCP address only and manually entered my DNS server addresses but still no luck on resolving names with DNS. At the end of the day, I don't really care if I get this fixed or just get a new VMWare VM. (I can't create one because I only have the player.)
I have setup an static IP on this server, it will ping internal sites , but when I try to browse the internet it does not do anything. I have set up the gateway, the firewall, and the domain fie, but still no luck.NOTE: When I try DHCP it will work ( it will resolve the DNS of the pages), but since this is a server it requires an static IP.
View 2 Replies View RelatedI have an RHEL5 server running BIND. I'd like to be able to resolve internal, non-FQDN names such as "wiki" for the company internal wiki. in my named.conf file...Named-checkzone returns no errors, and nslookup works when specifying the server explicitly, but no browser resolves the name when entered in the address line. I know this by no means a standard use of BIND, but I'm sure someone out there's pulled this off. I did see when googling someone suggest "load the root zone (.) as master, and add your "hosts" as TLDs, using CNAMEs", but tried that and probably did it wrong since it didn't work.

View 5 Replies View RelatedI have a windows PC and a fedora 13 linux box. When connecting to the linux from windows, I'd like to type the hostname instead of the ip address. Apart from setting the hostname, what do I have to do to publish my hostname on the intranet. (set up a nameserver?)
Though hostname works on the linux box, even this fails: nslookup myhostname Also I'm a newbie. I've tried installing some packages like samba and dhcp, using yum...;service chkconfig... and then checking whether nslookup or nmblookup work with my hostname. But it's just guesswork. Under system -> Administration there is no network option. but it is not clear what package is needed to install it, or whether such a thing is supported in fedora 13. I did try system-config-network, but it has few options none of which pertain to hostname resolution. The fedora manuals dont seem to cover it, at least in recognizable plainspeak to me.
I configured my dns server running on redhat5(test.com, ip-192.168.10.1), all is working perfect on the server its-self and on the client machine(xp), it cant resolve the name [url] but can resolve when i use [url]are ok, nslookup displays the following error:
The reverse is working fine from the redhat machine, NO firewall on the client xp machine xp as host name is added in /etc/hosts
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?
