Ubuntu Networking :: No Internet When Static IP / DNS Set Via Terminal - Fix It?
Jan 11, 2010
I'm having an issue with a new install of 9.10. I've set the ip address in /etc/network/interfaces and I've also set DNS servers in /etc/resolv.conf.
The issue I am having is that no address resolves, nor can I ping outside of my LAN. I've wanted to avoid using the GUI network setup because it hasn't been saving the information correctly. Here are how the files look code...
I don't know what eth1 is; I only have 1 ethernet connection in that machine, so I'm thinking it may have something to do with that. However if the machine is using eth1 (which has no address) than it follows that I shouldn't be able to locally ssh or vnc into it, right?
I set up a static IP address yesterday, following the instructions at the top of this page and since my machine no longer connects to the internet (although all other machines are connecting fine, so I know it's a result of this change).
my computer with ubuntu 9.10 is in a LAN. We use static ip and do not have dhcp. I can go up to our server and browse our website but cannot access internet. my ifconfig, iwconfig, lspci are as follows...
I am currently facing a weird problem, It's that the internet connection becomes extremely slow when using static IP instead of DHCP when Im connected through a cable! The local network seems okay with both, but differs when using the internet!
I've ran a ping test and got the following results!
using static IP
Code: $ ping -c 3 google.com PING google.com (209.85.153.104) 56(84) bytes of data. 64 bytes from 209.85.153.104: icmp_seq=1 ttl=42 time=343 ms
[Code].....
When I used static IP i received only one packet while when using DHCP i received all three!! Also I lost 66% of the packets when using the Static IP connection! And most importantly, the speed, DHCP connection was 8 times faster than Static IP connection!
currently running ubuntu 9.10, the internet connection im hooking up to is a router from a friends personal dish internet (were all deployed to Afghanistan). Here is all the static information that i need to input.now i have all this information input in windows 7 and it works fine since its all broken out exactly how it was given to me in the ipv4 settings page. wicd in ubuntu however wont use these settings.
I don't know where to put this, or even what I'm looking for.
I've tried for 6 hours today to get my WPA2 wireless to work as a static IP on my laptop to no avail.
Basically I put things in correctly (at least according to that thread) but I get no interent. When I restart I get the correct IP address but no internet pages will load.
The network monitor I have on my panel shows that it is trying to send and receive information, but I can not get my pages to load.
I'm desperately in need of help, but I really don't know how to even ask for it correctly.
But to start here is my interfaces file (one config of about 15 I've tried).
I recently used this process to connect my Samba network to be able to access and allow Windows XP machines to access my computer on my office network.
For various reasons, all the XP computers on the network are set to fixed (do we say static?) IP addresses with manual DNS. Hence I realised during the Samba setup that I had to set a static IP on my Ubuntu machine similar to my Windows static IP's (ie 192.168.10.?) in order to be able to see the Windows share PC's properly.
Once I set my Ubuntu machine to static IP of 192.168.10.3 with subnet of 255.255.255.0 and gateway of 192.168.0.1 then I was able to access and be accessed by PC's on the network. However I couldn't access the internet after this. I input the DNS server in the edit connections as you can see per the attachment. All these settings (except the IP address obviously) were all now exactly the same as the PC machines, and I thought I'd now be able to access the windows network, as well as have access to the internet, however, even though my wired network is connected there is still no internet access.
I'm using the GUI under network connections to make all these changes if that is important. I can't understand why this doesn't work?
I am a windows user with no linux experience prior to Friday. Im setting up a music server (SqueezeCenter) running Fedora 10.
With the help of posts of this site Ive made good progress with complicated stuffnamely getting Samba and VNC working. My Fedora machine and my windows machines now see each others shared files, and I can control my Fedora machine from my windows machine. (The Fedora machine will ultimately be headless.)
But Im having trouble with a seemingly simple issue setting up my Fedora box with a static IP address. With DHCP enabled on my network Ethernet adapter, all works fine. I then used the System>Administration>Network menu to disable DHCP and to assign the same IP address that DHCP chose. When I do this, two cases need to be distinguished:
1. If I keep the box checked for Controlled by Network Manager, the Network Manager Applet reports a network connection, I nevertheless cannot access the internet, but my Fedora machine is able to communicate with my Squeezebox music player (connected to my network via my DSL modem Ethernet connections, and with a fixed IP address). 2. If I uncheck the box Controlled by Network Manger, then the Network Manager Applet reports no network connection and my Fedora machine is not able to communicate with my Squeezebox music player (and I of course have no internet connectivity).
Ive seen references on other posts suggesting that the Network Manager service be disabled. But I see no way to manually configure the network.
I can access internet when my eth0 is set toDHCP client. But when I set static I can ping goole.com... but my Firefox browser doesn't connect to Interent!
I have a fedora 14 box which has a static IP and I can not contact the internet or even my gateway router.I know it has to do with my kernal IP routing table but I can not find the command to do what I need...Here is my kernal IP routing table
I need to reinstall my GUI but all I can access currently is a terminal, I have the encryption key and SSID but have found all the how to's I've read really confusing since following certain steps on them give me error messages, I'm connecting wirelessly to wlan0.
First, the network manager would show up on my girlfriend's profile (hers was the first one we created) but it won't show up on mine and it would not detect any internet connections. I found another thread that told me to type "nm-applet &" into the terminal, which works great. It shows the network manager and auto connects. But as soon as I close the terminal, it auto disconnects. Anyone know why and what I can do to make the network manager icon stay besides keeping the terminal open?
I also issued the command sudo iwlist ttyUSB0 scan it gives this as output ttyUSB0 does not support scanning
I also issued the command sudo iwconfig ttyUSB0 essid "MTN DEFAULT" iT GIVES THE OUTPUT Error for wireless request "Set ESSID" (8B1A) SET failed on device ttyUSB): no such device
How can one find out the essid value of a broandband network? How can i connect to the internet from command line for a broadband network?
My Internet connection works.Using no VPN connection, I can access the Tnternet from the gnome-terminal (ping, apt-get, lynx), as well as from any GUI application.As soon as I establish a VPN connection via openconnect, GUI applications such as firefox, transmission and thunderbird still work.But terminal applications (such as mutt, apt-get etc), some daemons (like mpdscribble) and some GUI applications (such as the easytag cddb search) don't work anymore.
When I fire up my F10, I get connected to the Internet through wireless automatically. I jus wanted to experience how the CLI- Command Line Interface world is and to test the text based internet apps like elinks,lynx etc.. So I changed the runlevel to 3 in my /etc/inittab file. Now when I fire it up, it gives me the terminal.
The problem is I am unable to connect to internet. How should i connect to the Wireless Access Points.. n also here internet is under a http proxy ...so how to configure the connection.
I have tried a lot, like
Code:
I have used this part of script many times in runlevel 5 i.e X mode under gnome for spoofing my wireless adaptor's mac id by adding a line before starting the NetworkManager service.
Code:
I have also tried something like
Code:
But this one shows nothing(no output just stays blank) I dont get why it doesnt work under runlevel 3..
I'm trying to connect to the internet though the terminal and I think i've determined my key is off.
Here is what I do:
Code:
So form this i go:
Code:
where the last four #### are actually the numbers but ii'm not sure if it's possible to reverse a wep. My connection uses wpa & wpa2 encryption but doesn't accept that key. I'm not sure what my key is supposed to look like or be but i'm pretty sure the key is whats keeping me from connecting. If I change my key while browsing the internet i can't get any information. So is it possible to just put in my pasword. Or what is the key supposed to look like?
I got this message on Friday from just one domain. uote:mailsrv.forthnet.gr #<mailsrv.forthnet.gr #5.5.0 smtp; 554 5.5.0 Your message was considered to be spam by the FORTHnet Antispamming Policy and was not delivered to the recipient. The following spam tests returned positive for this message:FORGED_RCVD_HELO,RCVD_IN_BRBL. For further information visitWe are not a spamming community but it seems we have a statice IP address that has a Reverse lookup to "myipaddress.static.lyse.net" and not my email domain. Would setting a cname mail.mydomain.no -> myipaddress.static.lyse.net cure this problem or are there more tricks to be performedOnce I have cured the FORGED_RCVD_HELO I can move to getting the IP removed from BARACUDA.
I wanted to give my computer a Static IP so that I can easily connect to it from other computers: ie Mythbuntu.This is what I did. I set it with a static to 192.168.1.107. My gateway is set to 192.168.1.1, and 255.255.255.0 for the subnet mask. I'm using default settings on a Linksys wireless router.I've rebooted several times.Nowthen, I can connect to the computer from my laptop via the IP.Even my Iphone can connect to the computer through that IP, so I've successfully set it's IP to static, but I cannot connect to the internet.
I imagine that there is already a thread for setting up a static IP, but I haven't been able to find it yet, so here we go.I have recently installed Fedora 15 on home machine. I have a very simple home network. Belkin wireless router with Window and Linux systems. The router is setup to be DHCP server. Router is setup to have lease time = Forever. Even with this setup, my router is assigning different IP address for my linux machine every time I boot the machine. So I would like to setup a static IP on my Linux.From my research so far, I'm suppose to make some changes to the file /etc/sysconfig/network-scripts/ifcfg-eth0. But I don't have this file in this folder. Should I just create this fil
I was trying to assign the static IP address of my internet connection to my home server and managed to make a mess of it. I've configured the router to assign it the address every time but when I rebooted everything the server is cut off from the network completely (rather unfortunate with a headless server...). The only file I've edited on the server when trying to do this is /etc/network/interfaces, everything else network related is default. My intention in editing the file was to make the server accept the IP address assigned by the router since the router was already configured to assign the right one. I put in
Code: inet dhcp in the /etc/network/interfaces file, is that wrong? What is that line supposed to be?
I have installed fedora 14 minimum install and I have configured my machine for Static IP but now i cant reach any external sites or repository, in fact all i can do is ssh to the box. below is the configuration in my /etc/sysconfig/network-scripts/ifcfg-eth0 file:
and my DNS is setup to point to my ISP's primary and secondary DNS servers. I have brought the interface down then up after each change but still cannot ping anything.
I am trying to get a Slackware server up and running. I got a static IP working kinda. The computer gets a response when I ping the router but not the internet. Basically it can communicate with other computers on the network but nothing outside of the network. Its not a problem with the router because I have a couple other computer with static IPs. Also the network card works fine as it can get on the internet fine normally.
I need a linux distro who provides the following:1) Has an partitioner who can resize fat , ntfs ,ext* , .....filesystems.2) Has an excellent hardware support3) The installer can install console or graphic mode 4) The updating can be done via console5) In console can be configured internet via: static IP , DHCP , PPPOE and preferably to have support for USB modems.
I am struggling with what might be a minor problem. I have a home computer which I would like to setup as a webserver and hence give it a static IP address. It is connected to by wire to a router that is connected to the WAN via PPPOE. If I enable the network card on DHCP it works fine in browsing the web. If I now set it to static IP address it does not brown. Essentially I use the command setup to run the static IP setup. I then set my IP address to 192.168.254.X , the subnet mask 255.255.255.0 and the default gateway to 192.168.254.1 (this is the router connected to the WAN). I am able to ping the router, however when I try and browse on static it does not work. Your help will be most appreciated as this has taken way too long to solve and I have Googled as much without success.

How can I edit the system proxy setting using the terminal? Which file contains this settings? I want to edit this automatically using cronjobs, cause from 8-5 I need to use a proxy, but at home I don't need the proxy. How do I fix this?
I want to run networking on my laptops in different environment (home, office, airport etc). I found that Netowrk Manager assigns information from DHCP although I requested fixed IP and configured the gateway and DNS. If I reconfigure the DHCP server so that there is no free IP address, the laptop refuses to connect. When I remove the interfaces from the network manager, I get the fixed IP address, /etc/resolv.conf is not overwritten from DHCP but WiFi connection cannot be established, there is no dialog for setting WPA-PSK. The static IP address seems to be taken into account only if the DHCP server is not found. I need the static address at home and in my office because I need the possibility to ssh to my laptop from another computer but I need IP from DHCP possibly authenticating against RADIUS (Eduroam) when travelling somewhere else. Is there an easy way how to achieve it and how to switch profiles easily? And I cannot switch DHCP off because some devices in my LAN cannot work without it.
I have a dell inspirion 6400/1505 laptop running ubuntu 10.04 has 2 network controllers wired and wireless the wired is a Broadcom Corporation BCM4401-B0 100Base-TX (rev 02) the wireless is a Intel Corporation PRO/Wireless 3945ABG I have the wired configured for static ip 192.168.0.105 the wireless through network manager configured static ip 192.168.0.101 static works great,reboot and all is lost for the wireless default back to DHCP (wired stays static) and i loose the nameserver and have to reconfigure it all over. is there away to remove network manager an manually edit the wireless settings? i know how to edit the wired network interfaces do i just add wlan0 as a static ip ?
I'm using an Ubuntu server 10.04 that I set up on an external 2TB USB harddrive. I'm trying to get a static ip on it because I don't have to keep physically going to the computer to find the IP address so I can SSH and configure apache, mediawiki, and all the other cool stuff Ubuntu can do. I can't (aka really don't want to) use an Ethernet b/c its kinda far, but I don't think thats the problem - wifi vs. ethernet. It's connected to a laptop, so it has wifi built-in. I set up some static IP stuff in /etc/network/interfaces as posted here:
Code: # This file describes the network interfaces available on your system and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo iface lo inet loopback
# eth1 with dhcp auto eth1 iface eth1 inet dhcp
# eth1 with static IP # auto eth1 # iface eth1 inet static # address 192.168.2.106 # netmask 255.255.255.0 # network 192.168.2.0 # broadcast 192.168.2.255 # gateway 192.168.2.200
# wlan0 base (don't comment out the line below) auto wlan0 # wlan0 with DHCP #iface wlan0 inet dhcp # wlan0 with static IP iface wlan0 inet static address 192.168.2.101 netmask 255.255.0.0 network 192.168.2.0 broadcast 192.168.2.255 gateway 192.168.2.200 wireless-essid *removed* wireless-key *removed* wireless-mode managed
Where "*removed*" means that I have taken the text out of this post for security. At the top, I WAS going to do static ethernet, but I decided I wasn't really going to use and and set it back to DHCP (that what the commented part is). My laptop (and all other computers, actually) are on DHCP and for some reason switch between 192.168.2.* and 192.168.1.* because some configuration is messed up in my router (I can't fix it; no permissions). I have a samba and apache server on the server and want full-time access to it without ssh-ing and changing the ip to the 192.168.1 or 192.168.2 networks every time my laptop switches networks, respectively. I can't access the server with my laptop when they're on different "networks".
