The little home server of mine has bind configured as a caching dns server. I would like to configure it to resolve local host names. I know dnsmasq can do this, so what would someone need to do to get bind to do this?The network is entirely private with all private IPs which are distributed by dhcpd.(While writing this, the feeling creeps in that it would be easier to just have dnsmasq running.)
View 2 RepliesI bought a network printer, gave it a host name, address should be assigned by my cable or DSL router. Thats what DHCP and DNS is made for right?Now I will print to that printer from my (Lucid) Kubuntu box and resolve it by it's hostname.I can't ping it by printername, I can't ping it by printername.local.It works when I login my router, read out the IP address and hostname the printer registered at the routers DHCP-table and use that address.What can be done that a router transfers the hostnames it has in it's IP-table to clients upon DHCP resolve AND whenever a client get's a new IP-Address?

There's this domain, that is apparently a cname of a cname which is, I know, not recommended, but it's not forbidden by the rfc. The domain is [URL]. If I try with windows or bind dns I get this results in nslookup:
** server can't find [URL]: NXDOMAIN
but if I try with opendns I have some results.
> [URL]
Server:208.67.222.222
Address:208.67.222.222#53
Non-authoritative answer:
www.groenegordel.becanonical name = www.vlaamsbrabant.be.
www.vlaamsbrabant.becanonical name = waf.vlaamsbrabant.be.

Address: 193.53.37.42
With this I see it's a [URL] it's a cname or a cname. Is there a way to force bind to resolve this domain? Is this a limitation of bind?
I'm using NAT on an AP with linux. Is it possible to route an OUTGOING host not over NAT?
I'm using SNAT but could also use MAQUERADING I think. Because both are in POSTROUTING table and this table is the last one I don't think there is a solution or is there any solution?
Background:
I'm using a local VoIp client which I want to have an own ip for routing question in my network but don't want all other local machines as seperate ip's because if done so i.e. without NAT the routing table is very complicated ...
Problem:Your company network has internal only hosts / websites with names that end in .local, e.g.Your freshly installed Ubuntu machine works fine on the network, has internet access, etc. but cannot connect to these particular systems.Testing DNS with tools like dig / nslookup works fine, but normal name resolution with ping / telnet / browsers does not work.Solution:1. Open a terminal window2. Enter the command sudo nano /etc/nsswitch.conf3. Change the following line:hosts: files mdns4_minimal [notfound=RETURN] dns mdns4to this:hosts: files dns4. Press Ctrl-X, Y, Enter to saveExplanation:Ubuntu ships configured to do name lookups for self-configuring networks, based on the AppleTalk / mDNS / Bonjour protocol. In the configuration shipped for the resolver, this protocol is considered the final aurhority for the ".local" top level domain, and DNS will not be checked. The above configuration change eliminates this and restricts lookups to (a) /etc/hosts file, followed by (b) DNS
View 1 Replies View RelatedI 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 can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.
It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.
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'm finding that I can not resolve .local domains anywhere except with nslookup and found on the LucidLynx release notes that there is a problem with avahi causing this. Although the avahi service is convenient for locating printers and such can anyone else tell me what other services/options will be impacted on a default installation of Ubuntu if I disable this service?

View 14 Replies View RelatedI 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.
Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.
It's possible to configure a second level zone like this:
IN CNAME www.domain2.ext
For example, if I want:
host domain1.ext -> CNAME of www.domain2.ext?
and NOT only www.domain1.ext -> CNAME of www.domain2.ext?
Recently my home PC crashed and I had to re-installed it. I put a "clean" install of Fedora11, then copied my /home directory and some other stuff over from the old installation.I have a couple of PHP scripts I wrote, and one of them stopped working. It uses cURL, and when I enable error tracking I get:cURL error number:6cURL errorouldn't resolve host 'www.host.com'I started digging around and I found out Apache doesn't resolve anything at all, so it's not only a cURL problem. For example,
$ip = gethostbyname('host.com');
echo $ip; die();
returns "host.com" and not an IP address.My best guess so far is that Apache has no access to the DNS service (from command line and in browsers everything resolves). had a suspicion it's a SElinux issue and disabled it, but that didn't change anything.I found some old forum posts mentioning problems with chroot-ed Apache, but I haven't done anything to mine and in any case couldn't figure out what the problem was, or the solution, so I'm stuck.

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 1 Replies View RelatedI am using FC13 with BIND. I have a slave zone setup for my work domain. I can resolve .local FQDNs from the shell using NSLOOKUP but any .local FQDN from an application (GUI or CLI) results in "ping: unknown host". All other domains resolve fine. My guess is there is something with BIND that sees .local as an invalid domain suffix. Is there an option that I need to set/modify to force the resolution of .local entries?
View 3 Replies View RelatedI have an RHEL 5.3 system where NIS logins are working perfectly, but authentication doesn't seem to be working for non-root local users. I can't login either remotely or at the console with a local user, and I can't even su to them unless I'm doing so from root (i.e. when no password is required).
I've reset the password, I've deleted and recreated the user, and nothing. nsswitch.conf does have "files" listed as part of the config, which was really the main place I'd have assumed the issue could be. su gives "incorrect password", and ssh gives "userauth failure". /var/log/secure shows "su: pam_listfile(su:auth): Refused user <username> for service su", and same for the ssh attempts (with ssh in for su, of course). I've reviewed my pam.d files, and they seem to be the same as on a working machine, but I'm not 100% conversant with pam so I might be missing something.
How do you get linux to resolve local hostnames without DNS?
I've recently migrated from a fully windows home network, to a few linux machines and im unable to ping any local machines with hostname via these linux machines. i can ping IP and internet hostnames. also, windows > anything pings ok too. however linux > anything will not ping via hostname.
I beleive it's an additional service running on windows to resolve hostnames without DNS (wins/netbios).
DNS is done via a netgear DG834 router (DNS forwarding).
I know i could either use direct IP, or add machines into the hosts file, but im wondering if theres some way around that and to have it dynamically update like it does on the windows machines. static mappings seem a bit silly inside DHCP zones
I've seen some reports of avahi causing local network issues (taking over the .local domain), but i think this only extends to having to manually enter in .local after the hostname and even after removing avahi, the problem is still present.
