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 RepliesA 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 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 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'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 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 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.
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?
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.
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?
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.

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.
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 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:

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.
I have a netbook (toy) running Ubuntu 9.04. It has a wired Ethernet NIC and a wireless NIC. They both work fine but I have a question about how to integrate the netbook into my network.
Here is my network design:
Each computer has the reserved IP address devices listed in its host file.
So now comes the netbook, taylor13. For the moment I have hard coded IP addresses on the netbook as follows:
I have added to each host file:
I can now connect to the netbook with the desired interface so I guess all is well. However, this seems a little like a jury rig approach.
Is there a better way? Perhaps a configuration where I could request a connection to "taylor13" and the "system" would figure out what if any paths were available to the device and make the connection?
My router flippeth me the bird if I try to assign the same name to two IP addresses or the same IP address to two device names.
I also realized as I write this that I have a chance of stepping on 192.168.0.113 if I do not reserver it in DHCP.
We are making an embedded product based on Fedora 10 (this could change, but right now we stick to 10 because it works ok). We have an intel PC board with a build a normal ethernet adapter. Then we have a home build PCI-express card with 4 ethernet adapter build into a Xilinx FPGA (Xilinx Temac) (we got the driver from git.xilinx.com and modified it enough to make it work).
Now, by problem is: How do we control the device names of these ethernet adapters? It would be really nice to have them called eth0, eth1-eth4 in the order mentioned above, such our software always knows which to use for what.
Also: What to we do when the our adapter card is replaced because it is broken? A new card will have new MAC addresses and therefore the adapters will get new names destroying our IP configurations.
when I'm in my campus I saw things like this from tcpdump:
client-64-15.department.univ.edu
client-x-y.department.univ.edu
gw.nettokurabu.univ.edu
and my laptop got a name like that too (x and y being last 2 segments of the IP)out of curiosity, how to assign names like that to each IP? well, the names are not in dns records (can't resolve them to IPs)... when I set up (illegally) my on subnet with a routing software the addresses I used also already have their name without me configuring it before...
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.
Is it possible to have one static IP address with a NAT network forwarding each domain name to certain internal/DMZ IP addresses? I know you can do it by port but if both websites are on port 80 can you forward to the corresponding server on the dmz.I ask this because I noticed the website braemere.com.au had to be typed into a web browser and entering the IP which is 202.47.5.7 did not take me to the website.
View 5 Replies View RelatedI found problem in FC 12 release. I installed fc 12 to server (earlier there was FC 7). Then as always i realised that names of interfaces (eth0, eth1, eth2 .... eth9) changed after install. eth0 became eth9, eth1 became eth5 ... Earlier on previous fedora releases i solved this problem correcting HWADDR in ifcfg-eth files, so i linked MAC addresses to names (eth0, eth1, eth2) as i wanted in a right order. Now I can't do this. After correcting these files and restarting network sevice i constantly get a message: device ... has different mac than expected. I looked ifup-eth file and compare it with the same one in fedora 7. And i found that in fedora 7 there is function rename_device which processes if HWADDR value doen't coincide with real mac address value. See code:
# remap, if the device is bound with a MAC address and not the right device num
# bail out, if the MAC does not fit
if [ -n "${HWADDR}" ]; then
FOUNDMACADDR=`get_hwaddr ${REALDEVICE}`
if [ "${FOUNDMACADDR}" != "${HWADDR}" ]; then
curdev=`get_device_by_hwaddr ${HWADDR}`
if [ -n "$curdev" ]; then
rename_device "${REALDEVICE}" "${HWADDR}" "${curdev}" || {
echo $"Device ${DEVICE} has different MAC address than expected, ignoring."
[Code].....
But in fc 12 release there is no function rename_device!!!!!!!!! So in this case if HWADDR value is not the same as FOUNDMACADDR value (which equal to REALDEVICE mac address) i just get an error message So I can't change interfaces names, as result i can't organize right order of network interfaces as it was earlier on fc7.
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.
Since two days i m not able to browse websites using the domain names but able to ping/browse using IP addressed. I have done the following:
1. Using wireless i m able to get IP address of DNS (8.8.8., Gateway, localhost & router ip address
2. Disabled wireless and connected ETH0 but still the same problem
3. not able to edit resolv.conf
sudo gedit resolv.conf

I am building a custom RedHat+<our-software> installer iso for our own appliance. I am using Red Hat 5.4. The appliances has two on-board eth interfaces. On the back panel of the appliance, these ports are marked 1 and 2. When I install RH, I find the device names assigned such as eth0/eth1 are arbitrary. I understand this is to be expected with kernels 2.6+. Most of our customers connect their eth cables to the port marked 1 on the back and assume they should configure eth0 to make the device reachable. However, sometimes port 1 gets assigned "eth1". This is not a blocking issue, but its going to confuse our customers and we wanted to make it easier on them.
From reading online discussion boards, I know HOW to switch the assignment of the eth names. However, what I am do not know is whether I need to switch them at all. So I have two questions
1) Is there anyway for me to tell which eth mac corresponds to which port on the back? Since they are soldered on the motherboard and not movable, I would think there would be some way to figure out that x mac address corresponds to the upper port (marked '1' etc).
2) Is there a way to tell this by running a linux command? We need to do this automatically so I need to be able to figure it out at install time from the kickstart post-install or similar.
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:
Code:
In my network my proxy / firewall (iptables + squid) works as dns forwarder. I needed to configure an url at my /etc/hosts in my linux boxes which are behind the firewall into the lan. I want my machine to look at its local /etc/hosts file before querying the dns to the firewall.
Despite I configured my /etc/host.conf this way:
My machine keeps resolving the name through the dns forwarder (firewall) and not from the /etc/hosts file first.
Is there any action needed after configuring /etc/host.conf? Any service to restart?
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?
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.
