I installed ubuntu 10.10 today and when i open the browser it doesn't show any sites. I tried
> ping www.google.com
ping : unknown host www.google.com
> telnet > open localhost
[code]....
I have this annoying problem since day one.I am testing out Red Hat RHEL5, everything is fine except DNS look up.If I ping www.google.com, it doesn't work, ping ip address it all works;if I bring up browser, put www.google.com it doesn't work, can't find the name, however, simply put ip address there it works.My DNS seeting seems ok, and the DNS works from Windows box.
View 2 Replies View Relatedhow to go about getting Ubuntu to receive an ad-hoc wireless ICS enabled connection. The internet connection is shared through a virtual machine running XP (with the USB wireless dongle under XP's control), on my desktop PC, in order to escape my ISP's no NAT policy. Ubuntu is on both the desktop PC (the sender), and the laptop (the receiver). The desktop and laptop also run windows 7. I managed to get my laptop Ubuntu to connect to my virtual machine XP, by setting the IP, subnet and gateway of all wireless devices, as was suggested in [URL] - I did use the Network Manager GUI, but pinging the desktop doesn't work.
Even with the IP configuration, Windows 7 on the laptop receives the internet fine. The next step is getting Ubuntu to receive. I can do any kind of configuration in a virtual machine, such as install Ubuntu. In virtual machine XP I used 192.168.0.1 with subnet 255.255.255.0 and gateway 1.1.1.1. On the laptop Ubuntu 192.168.0.2 same everything else. I understand nothing about networks. I know there is stuff I can do in the console, but how will Network Manager cope with me doing that?
I use my computer as a gateway to the internet for the rest of the house which is split into two LANs. I also have VPN's linking the office side of the LAN to a remote site. All of the PC's other than mine that should have access to the VPN works, but my PC doesnt and I firmly believe this is because I need to add a static route. ping 192.168.10.1 doesnt work but ping -I eth2 192.168.10.1 does. 192.168.10.1 is the remote router on the other side of the VPN. I've tried this route:
Code: route add -net 192.168.10.0 netmask 255.255.255.0 gw 192.168.1.1 dev eth2 192.168.1.1 is my computer... the gateway for the rest of the house/office. My computer has a quad NIC, only 3 ports are used. WAN, LAN1 and LAN2. Aside from this routing issue, I have everything working perfectly.
Ive got a problem on my server ....installed Debian 5 , Webmin and than syscp settung up syscp ready ....
I try to ping "localhost" ansver ping: unknown host
I try to ping "localhost." there is a host with IP 127.0.0.1
I need it to change it in "localhost"
Is that the bind9 maybe?
I am using an virtual machine. where I need to ping from one machine to another. earlier I was able to ping. But after going to google.com once, I cannot ping back to this machine.
But if I gave ping -I eth1 <IP> then I can ping.
I cannot install any package, so tell me solution which includes not installing any package.
I can't seem to get ping to work on my home computer. I actually have two separate installations of Ubuntu 9.10. One is at home, sharing space with Windows Vista (dual-boot) on a Dell Inspiron 1525. The other is at workusing Sun VirtualBox on a Windows XP host. ping works quite well at work, through VirtualBox. For example, Code:ping linuxcommand.org always gets 0% packet loss. However, when I do the same thing at home, I always get 100% packet loss.

The same setup works fine in Ubuntu 10.10 setup that i have.
When I ping a destination IP address, it responds. However, when I try to telnet or ftp or sftp to the same IP address, it does not connect.
I do not know the physical location of the machine.
I run an centos server. From the console I can ping google.com and get a reply. But when I ping another address say xyz.com, the IP address is resolved (11.22.33.44) but there is no reply. In the same network in our office from my desktop I ping [URL] and there is a reply.I turned of the firewall but still the same problem.

Code:
# brctl show

I can ping and ssh to the server ...
Then I try to copy (scp) a file (2.8 M) to the server and, near the end, the copy stops and the server stops responding to ping and is not able to ping nothing except itself.
"ifconfig down ; ifconfig up" and the server is on line again.
I have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.
I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:
Code:
Ping by IP - the responses come VERY quickly one after the other:
Code:

So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.
I have recently installed ubuntu 10.04. After some days of trying I can say that ekiga doesn't work with 10.04. With the same computer I was perfectly able to use ekiga with ubuntu 8.1, the 10.04 gives me connections problems.... it simply say says "Could not register (Failed)".I'm trying to connect with my voip provider (12voip.com) but it seems that I can't. I have even tried other programs like empathy, Twinkle, QuteCom but with none of them I can connect with my voIP provider. I think there are some connection problems but I really don't know how to face them. We have to configure router in 10.04 for sip connection? Actually I can't phone at all.
View 4 Replies View RelatedI've tried to use netcat in the past and assumed it was my stupidity that was preventing it from working... but this is getting ridiculous. I'll execute nc -l 3333 on a server at 192.168.0.105 (after opening it on the firewall of course) then I run nc 192.168.0.105 3333 on my laptop (from 192.168.0.101). and nothing happens... i start typing and nothing comes up on the terminal.
I run nc -z 192.168.0.105 80 which should ideally do a port scan of port 80 on that server (of which I'm running a web server that clearly works) but it doesnt even give me any feedback. Nothing happens. Now when I use the verbose flag i see that I am indeed connecting to the specified port on the server successfully (so the port scan one is a success but only with the verbose flag... which shouldnt be the case I believe). But still once I have the server listening and the laptop connected... I type in both windows and nothing happens...

i've installed it on my parents old computer, mostly for downloading. But wired internet did work all the time but then i had to reset our router because of some problems and now it doesn't work anymore! But the strange thing is, if i put the cable on my own laptop with windows on it, then it works as normal.
So i guess its some kind of DNS problem, but i'm very new with ubuntu and also not so good with computers. Our network is simple just an modem connected to an router: Sitecome WL-341.

I just upgraded from 9.04 to 9.10. When I restarted, I admired the new login menu, then went to Firefox. I noticed that my wireless didn't work (it did in 9.04) Thinking I'd just need to reinstall the drivers, I plugged in the computer to a working Ethernet outlet with a working cord. I noticed that Ubuntu didn't tell me that Auto eth0 was connected. It didn't tell me anything. And then I went to Google and realized that the wired connection didn't work either. Then I came here on an iPod Touch and you know the rest.
Edit: And other devices work too on the network.

setup consist of three machines: 2 servers (A and B)(ubuntu) and my local laptop Server A is a company controlled server which holds project data Server B is our office local server, which we use for development purposes. The problem occurs when i ssh from my local laptop to server B. After loggin in, i execute a script to transfer data from A to B. This script mounts server A using gvfs-mount. It fails to mount completely and gives me the following error
Code:
Error mounting location: volume doesn't implement mount
However if i log onto server B, using the servers keyboard and monitor (using a gnome session) i can execute the line. To verify that it's something related to the ssh login, i tried the following: (My local laptop is also running ubuntu) from laptop open a terminal. See the gvfs mount work as expected. open another terminal and ssh localhost tried to execute gvfs-mount from the local ssh session and i get the above mentioned error. After googling a bit, i found that it might related to dbus (which i know _nothing_ about) and i tried
Code:
dbus-launch gvfs-mount and then tried to gvfs-mount server A, but it fails again.
