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 1 RepliesI 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 RelatedAnyone can point me to a document, page, or something that will tell me exactly how to implement DNS step by step. I don't mean just the concept, i.e. you'll need two name servers, and to download BIND, etc. NO, I mean command line commands and all. Step 1, step 2, how to register the name servers, how to resolve different domains, etc.
I'd really appreciate it, as I need to implement internal DNS and external DNS for my company soon. Our set up is pretty standard: Firewall, DMZ, Solaris/Linux/Windows servers, and Windows clients, etc.
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?
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 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.
For what purpose does "nslookup" command should be used? Any examples.

Not really a linux specific thing I have gooled the heck out of it and tried nslookup -a and a few other options nothing gets me what I need. The question is I have a machine with several aliases in dns. How do I do a nslookup and display all the aliases for a system.
I am trying to see if something it aliased correctly but i cannot list all the names a system is know by.
I am sure its something simple I am missing with a switch.
I am not so experienced with networking in Linux. I've successfully installed Red Hat Linux Enterprise 5.2 on a VMware host. When I issued nslookup command, it returns "connection timed out" error as follows:
Code:
[root@rac1 ~]# time nslookup rac1
;; connection timed out; no servers could be reached
real 0m15.038s
user 0m0.000s
sys 0m0.000s
My questions are:
(1) Is that error normal?
(2) Is there a way to decrease the 15.038s value? rac1 is the local hostname, so why it takes all that time to resolve it.
Following info may help:
Code:
[root@rac1 ~]# hostname
rac1.mydomain.com
[root@rac1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

I'm trying to find a command to tell nslookup, "I want you to try to resolve hostname X using DNS server Y, and if the lookup fails, just output failure do NOT fail over to some other DNS server as a backup and use it to try to resolve the same hostname."I'm trying to follow the man page instructions for doing this, but it doesn't seem to work. The man page for nslookup on my system (CentOS 5.5) includes the line:
"[no]fail Try the next nameserver if a nameserver responds with SERVFAIL or a referral (nofail) or terminate query (fail) on such a response."But if I try using that option, the output seems to indicate that after the lookup failed on ns1.afraid.org, nslookup failed over to 208.67.220.220 (the first nameserver listed in my resolv.conf -- an OpenDNS nameserver) and used it to resolve the hostname instead.
Recently I installed RedHat Enterprise 5 on a windows machine. The machine is configured to use DHCP, but I have been seeing some strange behavior if I do nslookup on the machine's IP:
[someuser@lin01 mydir]$ nslookup 10.5.x.x
Server: 10.10.x.xx
Address: 10.10.x.xx#53
x.x.5.10.in-addr.arpa name = xyz.something.
x.x.5.10.in-addr.arpa name = lenovo-d1690047.
x.x.5.10.in-addr.arpa name = pqdlds.
x.x.5.10.in-addr.arpa name = lin01.mydomain.com.
Where only the last entry of [URL] is actually correct, how can remove the other entries? I spoke to my IT Manager and he cannot see these stale entries in the DNS (we are using windows AD)
I 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.
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.
Running knode with 11.3 and KDE 4.5 (same problem with 4.4) it is

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)
View 6 Replies View RelatedI 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 thought, perhaps from one and one, have public IP blocked, but the funny thing is that from another PC that I have at same room (with Ubuntu 10.04 too) connected to the same internet connection (with the same public IP Address) works perfectly. What else can I check?
I'll post an scenario and hopefully you can help me understand the concept and put me in the right track and do what I intend, if possible. Let's say I have a dedicated server with 2 static IPs each with an associated domain, let's call them www.site1.com and www.site2.com. Now, apache is running on it, I'd like to redirect anyone coming from site1.com to /home/site1/public_html and anyone coming from site2.com to /home/site2/public_html.In short, apache serving 2 entire roots depending on the accessed IP/domain. Whether the sites root are in the same parent folder, such as /home/site/site1_public_html and /home/site/site2_public_html or like above doesn't really matter, as long as it works.Additionally, do something similar with Postfix, so that I can have it running imap/smtp for foobar@site1.com and foobar@site2.com on the same server.At this moment, both apache and postfix are working, and we host only www.site1.com with the respective foobar@site1.com. But I'm not sure how to proceed or even if it's possible to achieve the above solution.

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?
I have installed ubuntu netbook addition and all is good, but when I try to connect to internet I get comcast(my service provider) site. Which means I am connecting to outside world just need to know what to enter in Search Domains field.
All my pc's/laptops at home have 2 DNS names entered for ipvr4 listed in the field but no Search Domains field value specified and it works great off of wireless router.
Well here when I go to IPvr4 tab it seems like I am required to enter value in search domains field. The question is what do I enter there COMCAST domain? Like this one: hsd1.il.comcast.net?

View 1 Replies View RelatedI 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.
