Ubuntu Networking :: Can See APs But Can't Connect

Jun 11, 2010

I'm typing on my newly installed Ubuntu 10.04 Lucid Thingy-Magiggy on a cable!Being a windows convert with no experience in DOS/Terminal and the like, I have no idea what I'm doing and have no clue what's up with my wireless connection!Using Wicd Network Manager- I can see all the Access points in range, I tried to connect to my home access point to no avail.... "Bad Password"... (I was the one who set that password, I should know what it is!).

What's going on? I tried with wifi radar but that just crashed at the 'obtaining ip' bit so I guess that's the problem?On a evesham laptop with 32bit desktop edition. Wireless = IntelPRO/wireless 2200BG (i think)

-ifconfig
eth0 [irrelevant]
eth1 Link encap:Ethernet HWaddr 00:15:00:42:bf:de
inet6 addr: fe80::215:ff:fe42:bfde/64 Scope:Link

Ubuntu Networking :: Unable To Connect To The Internet But Can Connect To The Router

Apr 6, 2011

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.

Ubuntu Networking :: Internet - Cannot Connect - But Can Connect Through XP On VMware

Aug 15, 2010

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.

Networking :: Kubuntu - Can't Connect To The Internet But Can Connect To The LAN

Nov 12, 2009

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.

Networking :: 3 Nics - Connect To Internet - Share To Local Net - And Connect To Local Net - Not Working

Sep 15, 2009

I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.

It is running Ubuntu server 8.10

The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.

My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.

I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.

Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.

Ubuntu Networking :: Cable Modem Networking - Can't Connect To Each Other On The Home Network

Feb 14, 2010

I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

Ubuntu Networking :: Unable To Connect To A Small Number Of Random Websites: Otherwise Networking Is Fine

Dec 29, 2010

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net

As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)

ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

Fedora Networking :: Networking - Connect To The Internet Using BSNL Broadband Connection

Mar 6, 2010

I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.

There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

Networking :: Networking Script Doesn't Allow Local Machines To Connect To Each Other?

Jan 21, 2009

I wanted to be able to have separate NICs with separate IPs connecting to separate gateways on a machine so I could put an ftpd on each one. I tried binding an ftpd to each, and running separate instances of the ftpd. I tried virtual hosts.

NOTHING worked. I could either use one ftpd or the other. I could either connect via ssh on one IP or the other. the second I turned one NIC off stuff would work again. I messed with basic iproute commands, andnothng worked until I got this script to run, which allowed me to use each NIC independant of the other.

Code:
#!/bin/sh
#ip route flush all
ip route del default dev eth1
ip route del default dev eth0
ip route del table 1
ip route add table 1 to default via 10.10.10.1 dev eth1
code....

But now, samba client doesn't work. cifs mounting doesn't work either. It can't connect.

BEFORE I ran that script, I could connect via ssh, or to the ftpd running on the machine using a LOCAL IP - 10.10.10.2. AFTER, I have to use the external IP, or I cannot connect. I know that has something to do with it, but I do not have the advanced linux routing knowledge to redo the script or come up with a solution.

I have 10.4 and wish to connect to my XP MsHome LAN. Before ubuntu I tried the MEPIS distro and it worked first go as it must have been installed with the package. I can see all the XP boxes on my Linux Network Manager panel but when I try to get to them I get the 'Error can't mount' etc panel. I am now in Synaptic on the Linux box and samba is showing with a red icon next to it, but there are many other samba entries. Do I just need the one with the red icon next to it or others as well?

Ubuntu Networking :: Can't Connect To VPN.

I've been trying to get VPN to work but i keep getting the following error:

Code:

anon warn[open_inetsock:pptp_callmgr.c:329]: connect: Connection refused
anon fatal[callmgr_main:pptp_callmgr.c:127]: Could not open control connection to 94.75.253.244

anon fatal[main:pptp.c:357]: Child process died

I'm running 10.10 (had exact same error in 10.04)

I've followed all the instructions I can find but they all say you have to have: "Use Point-to-point-encryption MPPE" enabled AND have PAP ticked.

But as soon as i select MPPE the option to select PAP is grayed out! I can't have both!

Anyone gotten the free VPN from [URL] working in Ubuntu?

Ubuntu Networking :: Can't Connect To Wi-Fi?

Dec 16, 2010

I am running a Acer Aspire 5251 as a duel boot, Windows 7 and Ubuntu 10:10. which I upgraded from 10.04. The computer has a Atheros Comm. AR928X Network Card. I was using Network Manager to connect to the internet through a Belkin Play router. A few week ago I noticed I didn't have as much signal as usually. Then last week Update Manager updated my Ubuntu, after the update I had no internet connection through Network Manager. After I had exhausted all of Google lead I could find, everyone was bragging on Wicd and I tried to set it up following all the lead I could find, and it never worked either. The window 7 is connecting fine and has all along, so I don't feel like it is the antenna. I have Ath_hal and ath_pci drivers for the Network Manager and Ath9K driver and Ath-5K driver for the Wicd

Ubuntu Networking :: Can't Connect To Ad-Hoc

I've been searching for hours about how to connect Ubuntu TO Windows. Meaning Windows is hosting the Ad Hoc network, and I'm using Ubuntu to connect to it and use internet. All the tutorials I can find is about Ubuntu being the host, and I can't find any help about my issue. This is the only thing holding me back from using Ubuntu; I can't use anything until I get internet working.

Ubuntu Networking :: New Install 9.10 Now Cannot Connect To Net

Jan 6, 2010

I can't seem to get connected to the net. This is a new install of 9.10 and i last had 8.04 installed. I think that version got on the net automatically but the previous 3 versions of Ubuntu i used did not and i had to put in the dns whatever numbers. I think I have all the right numbers on hand but nothing seems to work. Wicd or network connections is set out differently from the previous version and I tried putting in whatever wherever but am getting no where. I can't seem to remember to use ip4 or 6? Or well I took everything back to what it was and also tried the modems(Speedstream 6520) page using a browser. No luck there. I googled and one page said use 10.1.1.138 and another said use http://speedstream but nothing happened. Not sure where to go from here....have i missed something?

Ubuntu Networking :: 9.10 Detect Wi-fi But Could Not Connect?

Jan 15, 2010

I could not connect to any wireless network on my laptop with ubuntu 9.10. Network manager detects all wireless networks avaliable, but could not connect to any of them. When I try to connect, system asks for wpa-key, but typing it gives no result. I tried home and office network, but it is the same. There is WinXP installed on the other disc partition and no problem with wireless connection at all.

I have Acer 3680 with broadcom wireless adapter 4318 (driver was installed via ndiswrapper). I've already spent hours, browsing the Internet, but it does not help unfortunately, so I'll appreciate any advice of experienced user.

Code:
lo no wireless extensions.
