Networking :: Windows 7 Intermittent - Resolving Host Aliases Against BIND 9.6.2?
Jan 15, 2011
I have a Windows 7 professional x64 pc that intermittently fails to resolve host aliases. The nameserver is a Fedora 11 system running bind 9.6.2-p2. Its cannonical name is trixter.intranet.org, and it serves several web sites, each with a different host alias: hg.intranet.org, svn.intranet.org, bugzilla.intranet.org, etc.
Occasionally, the Windows pc will be unable to find any of the aliased hosts, even when it can find the canonical name. The aliases will be un-resolvable for a period of several minutes, and then, with no intervention, they can be found again. Trixter can always resolve the aliases to itself.
Even stranger, when I use Cygwin from the problematic Windows 7 PC, it CAN resolve the hosts. I can ping hg.intranet.org from a Cygwin shell, but not from a cmd.exe window. Administrator privileges make no difference.

I just installed a dual boot XP/Debian 5.0.4 setup on my Dell 5100 laptop. I now have constant problems with "resolving host" when using Debian. The connection when using a browser or downloading is noticeably slower than when using Windows or my Ubuntu install on my desktop. Also, whenever using the Debian install on my laptop, both it and my desktop, which both connect through the same Linksys router, constantly show "resolving host" (Chrome browser) until it just timeouts. Rebooting the DSL modem sometimes fixes it for a while (although it's still slow even then), but it eventually happens again. Turn off the laptop/switch to the XP OS on it, and the problems disappear on both the laptop and desktop. Is this a known problem for Debian 5.0.4?

I have a strange problem with wireless internet connection. We have 3 computers, 2 of them with Win 7 and 1 with Ubuntu 9.10 + Win XP.
Now if all three computers are connected to the internet through wireless router, the computer with Ubuntu 9.10 frequently fails to resolves hosts using various web browsers. I have to disconnect and reconnect to the router to get internet back but it only works for a maximum of 1 minute before it fails again. If the 2 computers with Win 7 logs out from wireless connection then the Ubuntu 9.10 machine works just fine for long periods.
If i boot with Win XP internet works perfect even when the other computers are connected but i really want to use Ubuntu 9.10. The wireless chip is an Atheros 9285.

At work we run DHCP. hostnames have the format: computername.city.mycompany.com
I have a laptop runing Fedora 13 and a desktop I use for backups, etc. My laptop is named copernicus. Desktop is named galileo. If ping either hostname from itself I get back the localhost IP address. If I ping the fully resolved hostname it tells me unknown host. The desktop is exporting an NFS share I use for backing up work data. I need the laptop to be able to resolve host names to mount the share since we use DHCP. The desktop is dual boot and if it is booted into windows my laptop can resolve the hostname properly. What do I need to do in Fedora to get it to register a hostname with the DNS and/or DHCP server? Should the domain and the search path below both say the same thing?
Here is resolv.conf on the laptop (I am at home). The desktop looks the same, except for a different nameserver. Both computers can resolve other hostnames, just not each other.

I just set up my first ever bind9 DNS server running on ubuntu server 10.04. This server is also my gateway/dhcp server.
Here is what is weird: If I do a dig @8.8.8.8 dschuett-lmtl.scs.local from any of my clients it resolves?!?! Dig shows that it got the answer from MY Bind9 DNS server (and NOT Google's of course), but why is it still resolving when I'm telling it to use and external DNS server?
The other weird thing is that the SAME EXACT dig command above does NOT resolve internal host names if I do it from the Bind9 DNS server. - Which is what i would expect SHOULD be happening if done from the client machines...
Here are the dig results:
From any internal client:

I have this ISP grade Nameserver running on BIND 9.5 on Fedora Core 9 64 Bit.
Its been pretty working well for sometime until a last week when we noticed it stopped resolving for our clients using on our service.
It gives correct authouritative answers for our own ISP domain with the A, PTR and MX intact but does not return resolving queries back to clients.
Below are my files
This is the message from /var/log/messages
The 41.223.x.x and 41.215.x.x ip address are from our ISP subnet and so are our own clients being denied.
The box is also hosting our traffic graph server which is on a LAMP but listens on another IP/ethernet card.
So far the load on the server is minimal as is a Dell R200 rack server.

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?

Issue with the 'host' command that comes with bind-utils package.We don't have any browsing/name resolution issues except to the following two sites:
[code]....
command [URL] returned:
www.aeroplan.com is an alias for www.halb.aeroplan.com.
www.halb.aeroplan.com has address 207.34.195.17
;; connection timed out; no servers could be reached
;; connection timed out; no servers could be reached
[code].....
I have tried to run the "host" command against different DNS caching servers I have access to all produced the same timed out error. I called Aeroplan technical support to report the issue to them and from their perspective, they have no problem accessing the website.And we don't have any problem accessing any websites ourselves if "host" return A record lookup without the timed out error.
1. It's not our firewall filtering out packet. I tried it on external facing server without firewall and got the same result.
2. It's not our DNS caching server cause same errors are observed on our ISP caching server.
3. It works on an altogether network, from a Windows Vista desktop, through IE 8.

I am using Fedora 7 in my server. Currently windows server 2003 (Active Directory integrated with DNS) is running. I want to switch my DNS to Linux. In my small organization there are only 20 users using static IP address and the IP are mostly permanent. so should deploy name server or I just populate eateries in /etc/hosts file ?

I'm new to using a BIND DNS server. I currently have one set as a master zone on my LAN. My question is how can I add a record for my local lan that will resolve without typing in the FQDN? For example I want to be able to type "server" instead of "server.domain.com".

I am able to send a mail message to myself from a server without any problem...
But after I have updated /etc/aliases and added the line for all of root's mail to be routed to me....
Added:
root: myemail@company.com
and ran newaliases to implement it....
If I send a mail message to root, it does not get routed to my email...

I installed bind & did not install chroot. I set up a fictional domain kelly.local. I am able to resolve FQDN (example: angus.kelly.local) in both dig & nslookup & ping on linux boxes.
I want to be able to resolve bare host names (example: angus) using bind. I get mixed results.
(1) linux boxes resolve bare host names & FQDNs just fine using nslookup & ping, but not dig. dig gives error:
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> angus
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 15241

I have a samba mount in Windows, mounted from a local Linux devbox. The projects on this mount contain a lot of symlinked directories. They all work fine and look like normal directories to Windows. What I'd like to do is figure out for a given file what its real UNIX path is.The context is: in my editor I have a script that runs the Perforce open command, to which I pass the file location.p4.exe edit FILE_LOCATION
However, perforce will not understand this FILE_LOCATION, if on the Linux side part of the path is a symlink. It needs to know the real path.What I need is something along the lines of the Linux readlink command, which resolves symlinks in paths.

Is there any way to resolve the hostnames of windows machines from linux systems.My environment is 80% windows and 20% linux.Domain controller,DNS,DHCP servers are on windows 2003. In linux systems,we just create local user account based on the user account created in domain controller,and give the dns servers ip address in the network settings.Authentication of users will be done locally. how to join these linux systems to windows domain so that authentication should be done by domain controller as well as host name resolution of windows systems and linux systems..

I'm trying to get Synergy up and running between my Windows 7 (server) host and my Arch Linux (client) host. In rare exception, synergy works perfect on my windows host, however every time I try and run Synergy on my linux machine I get the following error in messages.log:
[code]...
I'm running Arch with a barebones Xorg install and SLiM with LXDE. I'm not sure what in the world is causing the problem and haven't been able to find anything of substance in a search.

Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu.
I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.

I have Fedora 12 (Fedora-12-i686-Live.iso) installed and booting in a VMWare workstation (version 6.5.3). I am able to login as the LiveUser.
I need information on how to access the drives on my host which is WindowsXP. My C: on the host is shared, and my network adapter for the VM is "NAT".
The only directory listed in my /mnt directory is "live".
My Fedora enviornment is "bare bones". There is nothing installed except for the original files from the "iso" loading procedure.
I also have been unable to get the VMWare tools installed, and I don't know if this is related. I don't mind bypassing this if this isn't required. My only desire right now is to access my C:

I am trying to set up samba in my CentOS virtual machine that is running on a Windows 7 host. I have found a tutorial in the How-Tos on this site but I'm not sure if they are exact and I'm paranoid about messing something up. The link to the tutorial is below. Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines? Please note: I am very inexperienced in the IT field. [URL]...

I have found that there are certain things on the web that I need to print, that simply refuse to work under linux. I have a samba printer server on one of my Slackware boxes and an M$ XP vm under Vbox that can access the server and see the printer. The only problem that I have is that it expects to download a driver from the server which isn't available and the HP driver installer won't install if it doesn't detect the printer. Short of relocating the printer to install the driver, does anyone know how to get the driver installed on the XP host? This is so much easier with my Slack boxes and CUPS!

On testing to see if the nameservers are reachableCode:root@ps1:~# ping 218.248.255.146connect: Network is unreachablePost title pre-pended with [DO NOT REPLY] dnsmasq on a recent Slackware 13.0 install is not resolving.

I have this in my resolv.conf file:
Code:
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:
Code:
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.

I'm on 11.04 on VMware 4.1, trying to get name resolution working. I can ping by IP other systems including on the internet. The network manager Icon on top shows a wireless icon, but the 'Wired Network' is grayed out and below that says 'device not managed'. What can I do to fix this? The interfaces file has the auto lo, then below that
iface eth0 inet static
stuff...
It doesn't work with or without the auto eth0 entries.
I have the nic set to DHCP and on my dhcp server gave it the mac address of the box to assign it an address, that is working.

My system is F13 (upgraded from F11) with all of the latest patches available. I haven't gone through and combined all of the rpmnew configuration files, but none of them seem to address networking.I'm trying to get subinterfaces (secondary IP addresses) to work in Fedora 13. So far, I have been able to configure them on the command line, but not to get them to persist on booting.My base address for the NIC is: A.B.C.254. It is statically assigned.
