Networking :: Resolve All Random Server Names?

Apr 9, 2010

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.
64 bytes from vvvvvv.q3g87uv8123907.qt1 (80.156.86.78): icmp_seq=1 ttl=249 time=55.6 ms

Ubuntu Networking :: NAS Server - Cannot Resolve Non DNS Names

Feb 14, 2010

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.

Ubuntu Networking :: Wireless Names Random Garbled Characters?

Apr 16, 2011

So... as I tried to connect to the internet i saw a load of garbled characters as names of wireless areas. I took pics w/ a camera (because I suck and don't know how to take screenshots) and I'll try to get them up. Its all nonsensical and is really making me concerned about the state of my computer.

CentOS 5 Server :: DNS Does Not Resolve Names Except To Localhost

Feb 9, 2010

We 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?

Ubuntu Networking :: 10.04 - Cannot Resolve Names Using DNS

Sep 16, 2010

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.)

Networking :: SLES 10 SP3 Will Not Resolve DNS Names?

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.

Server :: Using BIND To Resolve Internal Non-FQDN Names

Sep 3, 2009

I 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.

Fedora Networking :: F13 - Resolve Names On Intranet?

Jun 16, 2010

I 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.

Ubuntu Networking :: Resolve Local Network Names?

Mar 27, 2010

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?

Ubuntu Networking :: Windows Clients Lose Ability To Resolve Local Domain Names

Dec 2, 2010

I 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.

Ubuntu :: Gnome 3 Random Crashes / Resolve This?

Jun 4, 2011

About 1-2 times a day (3 today and it's just 9 AM here...) Gnome 3 decides to just not care about me any more, crashes and logs me out. No warning, no error on screen, just some black screen with text (like when shutting down the computer and it's stopping services) which lasts half a second, then back to the login screen.

Any ideas what might be wrong or where I could find some logs to post them here?

Debian Configuration :: Cannot Resolve Local Network Names Only

Jul 25, 2010

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.

Fedora :: Browsers Don't Resolve Domain Names While Other Programms?

Apr 16, 2010

I'm new here, so please be gentle! I recently installed F12 64 KDE on my Acer Aspire 1810TZ, could connect to the WLAN router but neither the native Konquerer nor Firefox could open any pages...

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?

Software :: Windows Computers Can't Resolve Samba Share Names In 10.04

Oct 2, 2010

After upgrading my ubuntu server from 9.04 to 10.04, the window computers couldn't resolve samba shared names anymore, the error code displayed by Windows was 0x80070035.

I was using the ubuntu server as a samba server, using 'share' as the security authentication method, it has been working very well under previous ubuntu versions but, after upgrading to 10.04, the windows computers can't access the server shares anymore; the linux computers don't have any problems (I can access the shares from linux).

As a workaround, I've added the name of the server in c:windowssystem32driversetchosts; but I'd like to know how to fix the problem without modifying every windows computer.

Networking :: Resolving Names From DNS Server ?

I have this in my resolv.conf file:

I have also used external DNS servers just to eliminate there being a problem with 192.168.1.67 (which many other computers are using successfully).

When I attempt to ping Google just to see if it works I receive this:

Code:

If I issue a host command against google.com I receive this:

I had thought that host and the name lookup routine would use the same DNS server and it should fail on the host command as well as the ping, but evidently not.

Networking :: Random Network Connection Loss On Debian Server?

May 15, 2011

I have been having this problem for about two weeks now where Debian's network and internet connection randomly fails. It works perfectly fine and hosts all the services I need for a while, and then without warning all network connectivity fails. I can't ping any other network device. Regardless of how much I try to fix it, the only thing that works is restarting the computer. First, the server went 7 days without a problem; then 5 days; now it lasted 2 days. Judging from my Teamspeak server logs, it crashed today at 12:31. I grep'd through my log files and found this information:

Networking :: Resolve CNAME With Bind DNS Server

May 5, 2011

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.
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?

OpenSUSE Network :: Cannot Resolve Host Names On Local Network?

Mar 9, 2010

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.

Ubuntu Networking :: Mount NFS - Failed To Resolve Server (Name Not Known)

Here's the entry in /etc/fstab:

Ubuntu Networking :: DNS - Clients Unable To Properly Resolve The Server's Ip Address

Oct 4, 2010

I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.

I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.

What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver

I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).

If, however, I put a dot in there: ping linuxserver.

I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.

The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.

Networking :: Ubuntu Server Cant Ping Or Connect External / Can Resolve Hostname And Domain

Oct 15, 2009

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.

Ubuntu Networking :: Unable To Connect To A Small Number Of Random Websites: Otherwise Networking Is Fine

Dec 29, 2010

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net

As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)

ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:
