OpenSUSE Network :: Name Lookup DNS - Unknown Host
Jan 8, 2010
I can lookup DNS hostnames with dig and nslookup, but nothing else seems to be able to resolve anything. ping, telnet, Firefox, everything gets "unknown host".
Many of mails sent from my mail server that are in Queue;The main reason is deffered by domains like yahoo,aol,etc.but there is one more error that i keep getting and that is Host Unknown,Below is an example from mail log,The catch is,test mail sent on the same email id sent from my personal mail from the same server i.e. url was deliveredHowever,another mail containing client information sent from customercare@mycompanysdomain ended up in queue.
There are more examples of the same,around 20 domain have the same problem.
I am trying to use a ZTE AC2726 USB EVDO Modem on openSuSE Linux 11.3 Gnome to connect to the internet. I have edited the /etc/wvdial.conf file as follows:
When I execute the wvdial command on the terminal the following error appears joey-suse:~ # wvdial --> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK .....
The /etc/resolv.conf file has the DNS addresses as below nameserver 212.49.70.22 nameserver 212.49.70.23
How do I resolve this and connect to the internet?
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 just intalled OpenSuse 11.2 on VmWare Server 2.0.2, the network is configured as Bridged and is sucefully configured a fixed IP in my network. Ok... The problem is... I can ping / trace all addresses from OpenSuse console. But I Can't wget all of them... It's a random thing. the same address that trace's ok, don't work for HTTP.
I installed 11.1 when it first came out. The PC I used gave up the ghost and I bought a refurbie, HP xw4100 and installed the 11.1 drive in it. All works except Internet connection. I am befuddled, bemused, confused and at a complete loss! The router on USB is not detected.

I have just loaded Suse 11.4 and have had (2) problems, 1st: When I installed some additional programs, such as, Scribus, the system showed them as installed but they did not show up in the "applications" menu any where. I finally tracked them down and edited them in and they work fine - Why aren't they being automatically placed into the menu system? 2nd: I have a home network setup and all systems can see and work with each other, however, the host system is not shown as if it did not exist at all. for example; if I go to "network services" and select "Samba Shares" if other computers are connected it will show them but not the host - if no other computers are connected it shows nothing. On my 11.3 system it shows the host eg; "Linux-12fx blah blah" this is of course my host machine. I have replicated all of my settings on the 11.3 settings on my 11.4 system - no luck!
When I type in hostname -f it says unknown host in /etc/sysconfig/network hostname=servix.example.com in /etc/hosts 127.0.0.1 servix.mydomain.com localhost localhost.localdomain 192.168.1.101 example.com www.example.com in /etc/resolv.conf search servix.mydomain.com COMCAST SNS SERVERS nameserver 192.168.1.1
In linksys router I have host as servix and domain as example.com. So why is it returning unknown host?
When I open Konqueror, on Fedora 15 KDE, it opens to the default Start Page just fine. When I try to visit any other website, it gives me an Unknown Host Error. The documentation I found for KDE just said that if I get that error, it means that either the website does not exist or I am not connected to the internet, but I'm quite sure I'm connected to the internet.
I am using ubuntu 9.10 and I still cannot figure out this thing. I work behind a proxy managed by my university. Now, I cannot ping the other users on my network although they can ping me. Not to mention, I also cannot ping [URL]... It says : ping: unknown host [URL]... But I can ping the proxy server.
EDIT: Thread name should be "No network on XEN guest ofcourse". I am trying to run OpenSUSE 11.3 as guest in OpenSUSE 11.2 as host. First problem I came across was libvirtd service wasnt started and after that I was able to install guest OS. Now there is a problem as guest doesnt have connection with internet. Here is the script for the guest
this issue which has suddenly occurred on both my Desktop and my Laptop. When I try to configure an IP address to any interface I get the following error....
I get this for ethernet interfaces as well. I do not understand what is different as I was able to configure the ip address only the day before yesterday on the laptop..? The Desktop has had this issue for about 3 weeks now.
OpenSUSE version: 11.2 *and* 10.0 I am unable to send email. It appears I am being blocked by my ISP [URL]... A Wireshark trace shows ICMP type 3 Code 13 - "Administratively filtered". It's important to note that I don't know exactly when the problem started, because I seldom use my ISP email account, I use Yahoo web mail due to the "throwaway" nature if I get hit with spam. I only discovered the problem when testing the functionality of 11.2. I suspect the problem started several months ago: I restored openSUSE 10.0 and the problem exists there too. I wish I'd sent that last email via 10.0 before the upgrade.
The weird thing is that using Windows 2000 box I can get a successful connection using telnet (Telnet also fails on the openSUSE box.) It appears to me there is something in the Linux TCP stack that Teksavvy doesn't like. I am on dial up and I pointed this out to Teksavvy tech support, as I am probably the only person left on dialup and the reason no one else has reported the problem
On my laptop (HPDV7), using DHCP for network access, KDE4.
I use Network Manager to manage wired and wireless connectivity.
I also have Samba server running for connectivity to Windows machines.
My router runs DD-WRT.
How do I tell this HPDV7 system to propagate a Host Name up to the router?
In the DD-WRT status screen, I see Host Name as "*" associated with the assigned IP address.
I cannot, for example, ping my HPDV7 machine from my windows machine, I assume because the router (also providing DNS for my network) does not provide the name to address translation.
I CAN ping the IP address directly, and Samba connectivity from the Windows machine to HPDV7 works.
I am running 11.2 and set ssh to boot at runlevel 3 and 5 through yast and started the service through the terminal. I have turned off the firewall on my wireless router and in the local firewall. When I try to connect from a machine in my office, I get the following
Code: ssh: connect to host xx.xxx.xx.xxx port 22: Connection refused When I run telnet from the machine, I get: Code: telnet: connect to address xx.xxx.xxx.xx: Connection refused telnet: Unable to connect to remote host: Connection refused netstat -tlnp on my machine shows: Code: tcp 0 0 :::22 :::* LISTEN 31622/sshd

I don;t have physical access to the system and it is a server located in Europe. Fedora release 10 (Cambridge) is installed in it.
I've encountered a problem after doing a fresh install with xubuntu 10.10 (2.6.35-23-generic).some sites are blocked like [url]....if I do dig [url]....- I receive the A, CNAME records and the IP address and everything.when ping[url].... - I receive 'unknown host'.when ping <theipaddress> - I receive responses
I am trying to enable DHCP so that it will give out IP's to some XP boxes when they boot. I have had success doing it dynamically, but not statically using the host declaration. host xpTest { hardware ethernet 00:50:56:2A:3B:00; fixed-address 192.168.100.2; } My question is, what should the subnet declaration be if I only want to hand out static IP's like this? Also, the host is the same name that is specified in /etc/hosts correct?
I'm running openSUSE 11.2 (Linux piura 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux) and have a network problem. At work, ethernet works fine. When I plug it into my DSL router at home (which works with other computers), I encounter the following behavior: ping can resolve host names, however, traceroute and Firefox and Thunderbird cannot. It happens for both wired and wireless connections.
How I setup my NetworkManager to use the correct host name on my system, if that is possible. NetworkManager ignores the specified hostname and uses 'localhost', which is a bit annoying.
I'm having an issue configuring eth0. I'm using ubuntu 8.10 in a virtual machine (VirtualBox). The correct adapter is being used and it has worked in the past. I've tried placing eth0 in dhcp through the GUI and bash, but always get a 169 address or 127.
I just installed (n this 11.2 system) vmware server (v 2.02), to have access to a few small systems. One of them is a 11.1 guest which I just upgraded to 11.3, successfully (almost).
I have a problem, though: from the host I can not ping/ssh the guest.
Guest to host works fine (including names).
Code:
The firewall is down on both sides. I don't see anything with iptraf in the guest. The IP addres of the guest is correct, unless I'm too tired to see.
The internal network is behind nat done by the PC Router.The TP Link is recieving wireless signal from outdoors and it has switching and basic routing capabilities. I'm using the PC router for better routing options.PC Router (or R for short) is a triple-booting machine - Linux, FreeBSD and Windows. It has two lan cards - external (ext_if) - 100Mbps Realtek 8139 and internal (int_if) - 1Gbps integrated Realtek 8169.The problem is that all traffic from R to the network is slow - about 5-20K, while the traffic in the oppoiste direction is all right - about 10MB that is fine for 100Mbps cables, NICs and switches. The problem persist no matter the OS the pc R is running.I've tried some debugging on the situation as follows:
- put another PC at the place of R - everything is fine. That exclude the possibility of damaged cables, RJ-45s, switches and etc. - connected both of the NICs to the Internet while the internal network is being disconnected and they both work fine (no delays) - traffic shaping is not running - there is nothing in firewalls except NATing the internal network (and it is working fine). Actually these firewall rules have been operational for more than months and everything was fine untill a week or two ago. - changed the internal NIC with another - connected the internal network directly to the TP and all of the PCs are getting good network performance. Then connected the R machine to the TP as well and there was good performance between the internal network PCs and R. - R has good performance to the TP. In fact everything has good performance directly to the TP (when not connecting trough R). - the problem persist only between R and machines from the internal network.
