Ubuntu Networking :: Cannot Get The Server To Connect To The Internet
Jan 31, 2011
I cannot get my server to connect to the internet. I have tried everything. I can talk to my local network so thats not a issue. I think it is my dns and gateway. I am trying to use open dns but do not know how to configure it. Here is my configuration now:
I have dynamic internet connection. In my network one machine run glassfish server in port 8080 (it IP address 192.168.1.3). If I type http://192.168.1.3:8080/ that load my glassfish server page. What I want is using dynamic IP like http://<DynamicIP>:8080/ load my glassfish server page. How can I do it ? My router is Dlink GLB-802C > I haven't good knowledge about network.
I have a home network, with an OpenWrt router operating successfully as DHCP server (using DNSMasq). I'm planning to install LinuxMCE on my main fileserver and in order for this to properly detect devices around the home it requires that it is the DHCP server. That would be fine except that I sometimes power down the fileserver (eg. when my in-laws sleep in the spare room where the server lives) and that would leave me with no DHCP which creates problems (when my in-laws want to get their laptop connected to the internet).
One answer is to get new in-laws which would be OK except that I'm still pretty keen on my wife. Alternatively is there any way to set up a fallback DHCP server ie. the router would check if there's a functioning DHCP server on the network (ie. the fileserver) and if it gets no response it will serve DHCP addresses itself.
I have one pc on which I have installed slackware and samba (fixed IP, mask 255.255.255.0) I have another PC (also XP) which also has fixed IP running XP, and I can connect that to the slackware server easily My third PC connects to the internet and gets its IP address from the Cisco router(?) that provides the IP and mask on boot up.
I tried changing the IP and Mask on the slackware server to match the internet PC (which uses a mask 255.255.254.0) but the PC mask and IP changed on the internet PC I want the PC that connects to the internet to also be able to connect to the slackware server, but I see no need for the slackware server to also connect to the internet - I will mainly use it as a file server When I worked for another company I think the IT department talked about having 2 network cards in the PC that connects to the internet
On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.
I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.
However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.
Here are some outputs:
I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.
I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.
The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.
I'm using an wired connection to the router and have the server set up on an internal IP of 192.168.0.100. I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.
The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).
I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.
The ssh server I have at home is accessible from other computers on the LAN. However, on if I try to connect to it from another computer outside the LAN, I get a publickey error saying 'permission denied'. I use key based logins. I have set up port forwarding on my router and the funny thing is that the current configuration worked just once. Here is the output of ssh -v
Code: foobar@IBM-Ubuntu:~$ ssh -v <ip address of server> OpenSSH_5.1p1 Debian-6ubuntu2, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for *
When i boot my computer and open ubuntu version 10.04.1 the internet wireless connection i have connected automatically. Now, for one reason i don't know, the internet did not connect to the internet. The progam display a message to uncheck the checkmark in the File Menu. After doing this, i refresh the system but it still not connect.
When I open my browser in windows vista (I have a duel-boot system), my browser (Firefox) automatically goes to this page, and I log in, and am able to then use the Internet.
Ubuntu also searches for this 10.196.128.11 server, but it continually states "waiting for server to respond". I have checked all the settings I could find in windows and compared them to the ones in ubuntu, and they seem to be identical to me. I am using firefox in ubuntu too so I cannot understand the problem.
I have an Internet connection problem. The computer I'm using which is running Red Hat Enterprize Linux Server cannot connect to Internet. I can ping machines working in our local network. Static IP addresses, DNS, Default Gateway, Subnet mask, they all seem to be correct. I restart network interfaces but that doesnt make any difference. Other machines in our local network are connecting to Internet without any problem.
Yesterday I helped my neighbor install Ubuntu 9.10 on his PC. This PC had XP with many bad viruses is the reason for the change. This is not a dual boot setup. Strictly Linux. I know the hardware is fine because DSL communications was working at the time of the install.
I've found a few threads describing problems with the Network Manager and DSL. [URL] I'm in kind of a "chicken and the egg" situation. This Linux PC has no internet connection right now and many of these fixes are downloads via the terminal. However, at my house, I have XP running and online. Can I download these fixes and copy to a flash drive and install on his Linux box?
I have a Ubuntu desktop on my LAN that has suddenly stopped accessing the net, this morning it was working nicely. The computer DHCPs an address successfully, and it can access other comps/services on the LAN. Other comp have no trouble accessing the web.I've pinged my gateway, and I get a response, but pinging Google for example gets me a 100% packet loss.I've tried to release and renew the IP using dhclient, I've unplugged and replugged in the cable at both ends (didn't really expect it to work since it can dhcp fine), I've rebooted the switch, the router, and the comp, still I'm getting the same problem. I haven't played with any firewall settings either.
I'm just using Ubuntu for the first time, and am trying to get everything working on the Live CD before I install it. The only problem that I'm having right now is getting connected to the Internet. I'm trying to connect to my router, but it keeps asking for the WEP Key. I type it in and it pops up again a minute later. It works on Windows, though. I'm running Ubuntu 10.04 on an old Inspiron 8100 I got from a friend.
I'm pretty new to Ubuntu, and have run into problem after problem with networking. The current one: I can't ssh out or connect to the internet, and ping gives a "unknown host" or "network is unreachable". But I can ssh into my computer from others on my network. "route -n" gives 2 entries, neither of which is "default", which from my reading it seems like you need, but I don't know how to remedy that. Is this a DHCP problem?
I'm on a university network, so I doubt it's a problem at their end, but I don't think I changed anything when this suddenly stopped working. On a more meta level, is it normal to run into a different network connection problem every few weeks? I'm not touching anything, I swear! Every linux user I know seems to know ping/ifconfig/route/netstat like the back of their hand, and if it's always like this, it's enough to drive a girl back to windows.
Both ethernet and wireless connections are down, Windows on the same machiene works with both - not hardware problem. Networking is enabled in the applet, but WiFi indicator and ethernet adapter indicator do not flash. Problem appeared after I closed the lid of the laptop at night (set to suspend), but next morning battery was empty indicating that it failed to suspend. I could not find any "hardware manager" inbuilt to turn devices on.
I don't like using Windows, and internet is a necessity.
PS It's Ubuntu 10.4, Gnome on Dell Inspiron 6400 (x86)
I just installed Ubuntu and it won't connect to the internet. I have an HP Pavilion dv4 laptop. On the top of my keyboard area has my power button, volume and wireless switches (they're all touch sensitive). Anyways, when the wireless is on, the light is blue. Whenever I log on to my Ubuntu account, it just has an orange (meaning off) color, and I can't switch it to on (blue). I'm running Vista 64 bit right now.
i want to connect to Internet via 3G key. But in our country, the operator who is offering that service mentions that 3G key is not compatible with Linux OS. But, when surfing on net, i found some scripts that makes such a service working with Ubuntu 7.xx. I wonder if there is a solution with Ubuntu 10.10
I just installed Ubuntu 10.10 and it works fine, but will not connect to the internet. My wifi card has a CD with drivers, including one for Linux, but it has no 'install' file. I have ZERO idea how to even get to a command line place in Ubuntu [NOR what I'd do or need to do if I got there!!!!] - and need desperately to get online, for all the obvious reasons and to download all the missing drivers needed for things I do. My wifi card [if it matters is a ASUS 802.11n Wireless LAN Card PCE-N13.When I look at what is in the Linux driver folder is foreign to me as Chinese...so those trying to explain, please realize this is my FIRST Linux install and I don't know the terminology...and lacking internet can look up nothing.
I am unable to connect to the internet through DSL. I can use it in Windows 7 easily. I use a Broadband PPPoe with an user name and password along with a service name. I have set up a DSL in ubuntu and I have placed the required user name and password there and I have also entered the service name in the field between the username and password. But it shows to be disconnected every time i try to dial the connection. I have also tried with the "sudo ppoeconf" command and "setpppoe 1.0 software" and failed.
I cant connect to the internet, when i am about to connect to the internet its says you are now offline, then when I put my WPA key in and it starts to connect and when its finished connecting it says you are now offline again, the network name comes up but i cant connect
I tried using the ubuntu 11.04 cd but it didn't work so I had to dig out my old ubuntu 8.04 livecd. I had a computer with windows xp totally get wasted and I decided to do a clean install with ubuntu 8.04 and update to the newer version, however I cannot get the internet to connect (wired), I've tried figuring out of there is a driver problem but was not able to figure it out.
