Ubuntu Servers :: Can't Ping Loopback Or Domain Names / But Ip's Work
Jan 7, 2010
I have been logging into a server remotely and trying to set up a mailing list on it. The server is the newest version of ubuntu server: uname -a: Linux Themis 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:48:10 UTC 2009 i686 GNU/Linux.I noticed I could not download packages with apt-get or ping domain names, and I can't even ping 127.0.0.1.And do you think there is something wrong with the network card?
For clairification, I can ping. I have tried several IP addresses and 100% success rate. When I noticed the problem I was trying to run sudo apt-get update && apt-get upgrade After some time I noticed these error messages to start with
[Code]
I tried to ping the adddress security.ubuntu.com from my Windows machine to verify that I could connect and was surprised when I could. I then pinged the address 91.189.92.167 which is what my windows machine resolved the name as and it went though.
My thoughts on this are that when my Ubuntu Router came up, for some reason it did not incorporate the ISP's DHCP servers into the ip address it obtained. Sadly I know to view ALL IP infomation in windows via ipconfig /all command but I do not know what this is in the *nix world. need commands that I can use to check and troubleshoot this apparently DHCP issue so I Can start to update my server and expand on its services?
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 ** (gedit:4179): WARNING **: Hit unhandled case 0 (Error opening file: Input/output error) in parse_error.
i have registered two domain names that i want to use to connect to my ubuntu server. I was wondering how to do this i was looking at bind9 but that didn't work that great. The server is behind a router with firewall i can connect to it using the external IP address but i like to use the two domain names if that is possible.
This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.
In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
I have a debian server installed with a static ip. Now i am able to ping my ip, but when i try to configure a domain name with the nameserver as my ip, i am not able to ping the domain name
I'm not to sure this is the place I should post this, but couldn't find any place for it to fit. So here is the deal..I am running 10.10 with the standard LAMP setup. I am running a drupal 7 site no problems. What I need to do is run a multi site sub directory. (domain.com/newsite). So far the best I can do is get a directory index of the second site (domain.com/newsite), but cant run the installer. (I did the symbolic link to the doc root of the drupal install.)If I type in the url domain.com/newsite/install.php I get not found. I placed an index.html test page and it renders fine. I think I'm close but just not there yet.
Any ideas from anyone? I can get Sobdomains to work fine on a test mache, but sadly I need the domain/site to work due to lack of DNS support at the moment. I tried to get some info from the drupal forum, but everything always points to subdomin setups. I also posted over there, but it seems like the forums have very little support and are a bit on the slow side.
I have a domain through google (enom) I have one website which I host web forums My friend has a website which he hosts the frontpage We're on two separate hosts We're trying to combine the websites together and my friend wants to utilize his hosting.Is it possible to get this one domain to work on two webservers without doing a redirect? For exmaple: have [URL] be the frontpage and [URL] be the forums
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.
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.
So I'm looking to host potentialy three different...sites...I want to call them from the same machine. One is a radio station and the other 2 are just straight websites. So I wanted to know if I had to use different machines to accomplish this or can I alter maybe the http conf file or what. I did find this in the forums but wasn't quite sure if this applied to me.

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 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.
Here is my scenario and what I want to try and achieve.
I have:
Quote:
Server A = 192.168.1.5 (serverA.home.com) Server B = 192.168.1.6 (serverB.home.com)
Currently I have serverA.home.com domain name set up using a free dns service online. When I am anywhere in the world I just type the domain name it hits my static ISP IP via the free dns servers online, hits my home router, gets port forwarded to 192.168.1.5 Server A and I am up and running.
Now...
I have bought a second domain for serverB and want it set up like serverA but I am totally baffled on how I can resolve 2 domain names on a single network? I need (somehow) to try and tell the dns servers that when I enter in serverB.home.com it will hit my static ISP IP as above and then hit my home router but then get directed/split to Server B and not to Server A.
Basically all I want to do is name the machines and get traffic resolved to them.
I'm setting up a loopback server for work related testing. I have a small program that needs to be executed through telnet from about 200 IP's on the same network. On the server, I have to set a static ip, enable telnet login, and place my 2 program files in the appropriate folders so it will run. I have been on this for 2-3 days and haven't got far.
My /etc/Network/interfaces file is this... Auto lo iface lo inet loopback
The rest of terminal is filled up with these, and it states that the file only has 32 characters. I don't know if this is a privilege issue or not. I've read several threads on telnet, and lots of arguments about ssh, but I can't run ssh, so I need to enable telnet. There is not a security issue. I run a private network where the only valuable resource would probably be the text file with my IP address on it. Its also accessed by people that have very limited networking knowledge and no linux knowledge...
So, Set static IP Setup telnet server... Any takers?
I'm using Wordpress on Apache localy to keep a diary (it's convenient because of the tags). When I'm connected to any network (be it wired or wireless) my Apache (and Wordpress, of course) works just fine. But as soon as I go offline, I can't access the web server neither through browser nor by telneting to the 80th port. Pinging localhost works just fine.Here is my ifconfig when offline and when online:Online:
Code: eth0 Link encap:Ethernet HWaddr 00:24:54:6f:07:aa UP BROADCAST MULTICAST MTU:1500 Metric:1
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?
I have a centOS 5 server running apache 2 with it's web root at /var/www/html. By setting up a dns entry to point to the computer's IP, I was able to go to testing.myservername.com and reach the contents of that directory.My question is, how can I go about mapping multiple future domain names to folders that are under this webroot?For example how would i bind www.temporarydomain.com to the /var/www/html/temporarydomain/ folder and also be able to map www.anotherdomain.com to /var/www/html/anotherdomain/?
here are the steps that i have taken already to resolve and troubleshoot the issue. i can ping Google. i can browse the Internet i can browser the repo Index of / through my browser. i have insured that ipv6 is disabled through network configuration through yast.
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.
