I used my computer this morning before leaving for the office, but when I returned this evening, I am unable to reach the internet. Also the light on the mobo where the ethernet cable is plugged in is steady yellow.
My limited experience would tell me it is a hardware failure, but it seems so strange with nothing happening during the day. How might I best diagnose the problem from within Ubuntu (10.04)?
I use Fed 14. I have China Telecom internet. The wired dsl connection works fine, but the wireless won't work. It has WPA security. The password taken from beneath the router is n2nqrcqx. This password is accepted. Network Manager says I am connected to ChinaNet-TRtk, but in fact, I can't reach the internet via wireless. If I disconnect the cable, I can't get through. I have the settings on automatic dhcp. I have nothing in BSSID, I don't know what that is. I unchecked the box 'require ipv4 addressing for this connection to complete' Ditto that for ipv6.

I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.

But only Fedora can't connect anymore, the Windows PC has connection as well as my Mac OS X (I dualboot Linux on my MacBook). The Ethernet connection works as well, when I unplug the cable, Fedora gives me a message, but I just don't get into the internet!
Does anyone have an ides what I have to do? I don't know anything about network connections and I'm new to Linux...
I already restarted the Computer, but that didn't work, and Google didn't really held either.
My laptop has been working fine with ubuntu 10.04, and earlier today it shut down after running out of battery. I came to use itr and discovered that the wifi icon had disappeared from the panel bar, and it won't connect to the wireless networkor via a wired connection.I have had a play around with this, tried ping -c5 google.comresult was:ping: unknown host google.comand ping -c5 4.2.2.1result: onnect:etwork is unreachable.I have other computers connecting to this network and know that it is working fine.

View 6 Replies View RelatedI have a Windows XP virtual machine under Virtualbox PUEL 3.1.2. I have always been able to browse the Web or do anything else I wanted over the network.
Suddenly, the guest XP machine can't reach the Internet any more. There is no indication of any problem with the network connection. I checked my router, and the virtual machine is indeed getting assigned an IP address. So why can't it reach the internet?
Yes, the virtual network adapter is in bridged mode. It always worked that way before. I can see local network shares from the virtual XP machine, and even reach the Apache server running on the host OS (Ubuntu 9.10 64-bit).
Also possibly significant: Even though the virtual XP machine is detected by the router & assigned an IP address, the printer attached to the virtual XP machine cannot be seen by another Windows machine (a real one, not virtual) on the network. I never had a problem sharing the printer before. I have to share it from a virtual Windows XP machine when I'm running Ubuntu because there are no Linux drivers available (it's a Winprinter).
I recently upgraded my HP DV7 to 11.2. I did the install with wired network connection, my WiFi is always on as well. Install went fine, ran updates via YAST. I am running KNetworkManager, it loaded, configured eth0 and wlan0, prompted me for WEP keys and showed both connections working OK. I later found that when eth0 was disconnected, wlan0 was still connected but I could not reach internet sites. My router address was set as the gateway address and the DNS server address. Following several items on the forum, I tried 'dig' and 'route' commands.
I found that
Code:
HPDV7-Linux:/etc # dig [URL]

returned a valid URL for that server - DNS seemed to me working properly via my router.
I found that
Code:

I then opened the Network Manager connection editor, went to edit for the wireless connection and found under the IP_Address tab, Routes option box that both

Unchecking these yielded

I've installed apache2 on ubuntu 10.04 and everything works fine, but when I use functions that needs to connect to Internet, it doesn't work. Is there a simple setup I've forgot? I've been searching and looking for a solution, but I'm stuck!

I had internet connectivity prior to installing the updates. Now I can't reach the internet since installing the updates. I can reach my router, log in to the router I also ping the router but I can not ping the WAN side ip on the router.
When I boot into redmond, no issues, which is what I'm using as I write this.
I have security enabled, WPA2 Personal, not that I think that is an issue as I can reach the router, my server, network printers, and PC's.
I am running a Linksys router but have replaced the standard Linksys software with DD-WRT v24-sp2 build date 12/28/09 std. One note, DD-WRT does hand out IpV6 address but I have disabled FF from using IpV6 address along with the network connection configuration applet from accepting them. (I don't remember the applets name)
In the redmond world this would be a certificate error, is this the same type of an issue? If so how do I fix it?

I have set up my guest OS in VirtualBox so that it has a static ip and is using a bridged adapter. As a result, I can see the webserver that's hosted in guest from my host OS's web browser. However, for some reason my current setup does not allow my guest to reach the internet. What settings do I need to enable both?

I have 3 partitions: 2 linux and 1 windows.
I have been using the 3 OS regularly with no problems. But today suddenly, I had no internet connection with the 2 linux partitions which are complete independent, but no problems with windows. i can keep using the internet under windows with no problems.
I haven't touched any conf files.
I have a usb wifi internet connection.
I just noticed a change in my dmesg file when i start any of my 2 linux partitions.
At the end of the lines I have the following :
I have a problem reaching some hosts on the Internet, namely newegg.com and djangoproject.com. On the same machine and network connection using Windows 7 the host names resolve properly and I can connect to them. The host names are resolving in Ubuntu, but I cannot connect to them.

The network is working fine except for the fact that I can't reach anything on my LAN (can't even ping the router), but everything on the outside works just fine.

Where should I begin looking for faults?
Here, enjoy some data. I'm using my wlan0 interface, not sure whether eth0 works or not.

I am running a server that needs both a wired and wireless connection with static IPs, with wireless as the default link. I'm using the SMCWUSB-G for wireless. I was running Debian for a while and had some routing tables set up as in [URL].... Everything worked until I recently switched to Ubuntu Server 9.10. After the switch a weird behavior showed up: if wlan0 is down, eth0 works fine. But if wlan0 is up, I can't reach any host with either interface (even nameservers or the gateway I am supposedly connected to). ifconfig indicates that nothing is wrong. It's really not clear what is causing this problem. It seems like something has to be wrong with both the wireless hardware/drivers and the routing tables in order for turning wireless on to interfere with "ping -Ieth0".

I'm running ubuntu 9.04 and I have set up 2 ip aliases using the /etc/network/interfaces file http://pastie.org/775037 -- when I ping the main address 10.0.2.16, all works fine, same with the first alias 10.0.2.22 -- but I can't reach the 2nd alias 10.0.2.23 I get the following from ping:
PING 10.0.2.23 (10.0.2.23): 56 data bytes

My machine's IP address is 10.5.0.34 I can't figure out why I can ping 10.0.2.22 but not 10.0.2.23 -- seems like there is probably some kind of routing thing that I'm missing, but I'm confused how it would have gotten set up for 10.0.2.22 but not 10.0.2.23 -- hopefully someone out there has an idea -- or can point me to references where I might be able to learn how to debug routing issues on a network?
I have linux firefox installed on my notebook, and after having a bit of a problem with it, I did a full factory reset back to all the original settings. Now when I connect to the internet, some of the pages now are not displayed properly. For instance, when visiting E-bay, the listings look fine, but my E-bay page is all listed down the page, (if that makes sense) and I cannot look at any of the photos. MSN is also, how can I put this, spread out across the page. I have done a live update to see if that makes a difference, but no joy.

eth0 - external NIC, DHCP IP from ISP

IPTABLES set up to masquerade on eth0
I have a computer connected up via server's eth1. It's IP is 192.168.0.201 (/etc/init.d/networking restart) gives me a DHCPOFFER and everything, so DHCP seems to be working fine.

I have read many, learning linux,apache,samba,vsftp,ssh..etc from this forum but now i am realy stucked and confused. My samba server has always been reached from internal aswell external networks.
I have switched 5 months ago to Telfort network ( i am not sure... ) but as far as i know it was no poblem to connect the samba server with windows explorer everywhere.No i get the only the login screen when connecting from outside the network and when filling in the credentials it just come back with the login screen. I don't have any problems internal when connecting to these shares and supplying the credentials.
I've set up ubuntu server 10.04 x64 with kvm and bridged networking and installed win server 2008 as a guest os. The guest os has full access to the network including lan/wan but the host os can only reach my lan and not the wan. This is true even when the guest machine is powered off?I have to admit that my knowledge of networking, particularly with respect to linux is very flakey but surely if the guest has internet access this should also apply to the host? My only suggestion is an issue with mac addresses but i don't know where to start. Has anybody ran into this problem before?
View 3 Replies View RelatedRecently I've been unable to load web pages, hosted on my Ubuntu Guest in Apache, from my OSX Host. In fact, I can no longer even ping the Guest OS from the Host. In the past, when I did ifconfig on the Guest, I got an IP of 10.0.1.n. Now I'm getting 10.0.2.15--the default NAT Address. The thing is, I didn't change any settings recently. What I did do is run software update for OSX, Ubuntu, and updated VirtBox.
Current Versions:
VirtBox 4.0.8 r71778
Host: OSX 10.6.7
Guest: Ubuntu 11.04
why I can no longer access my Guest OS from my Host? I spent hours on this last night, to no avail. What would cause the Guest IP to change from 10.0.1.n to 10.0.2.15? As I say, I manually made no config changes.
I recently set up an Ubuntu server computer (10.04) with the hostname 'morbo', and with a static IP address. With all my other ubuntu systems i can ping and ssh using their host names, like:
[code]...
i can't reach it via 'morbo.local' nor can i reach my other ubuntu systems from morbo by their hostnames. I have seen a 'quick and dirty' solution which might help here : [URL]... , but i don't want to have to add every system to morbo's list and morbo to every systems list, and because it works without manual configuration on all my other systems, i don't see why it shouldn't be possible here. Currently everything connects to one d-link router - does this mean it is the DNS server?
I am not sure if this is a problem with my router or a problem with the fedora 12 server i am using.
- internal here means within my home network, external means from outside it.
I can access my server and webpage:
internally using http://192.168.0.192
externally using http://MYDNS___EXAMPLE.com
but I cannot access the server internally using http://MYDNS___EXAMPLE.com
This is a pain in the butt because I have all of my client software setup with an internal and external access point (ssh, proFTPd, http, MS Access database connected to MySql, etc.)
I have a simple home network with a windows and fedora clients. I'm running fedora 13, but I"m having problems connecting to the pc on certain ports from my windows pc. I can connect from windows to fedora using VNC, and even connect to my postgresql database. However, can not get connected to my Apache Tomcat or JBoss server. When I first installed the OS I went through and configured the firewall but have since disabled it (stopped service). However, I still can't get to the app/web servers.
