I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

up until about four days ago connecting to the local LAN was as simple as booting Ubuntu, and letting nm-applet automatically connect on Auto Eth0 But the other day it just randomly stopped working, with no cause that I can think of. I can still connect to the internet (This is via a PPPOE connection, running through the same wired interface) so it can't be a hardware problem with the ethernet port/cables themselves. nm-applet just stays spinning in circles, and nothing ever happens. I tried deleting the auto Eth0 entry, and creating another LAN entry with exactly the same settings, but I still get the same problems. way to completely restore nm-applet settings? Or some other way to give me access to the local network?

I recently setup motion on one of my computers with a USB camera. On that computer if I type [URL] I can see my live video. If however I type [URL] on that computer or any other on my wireless network, I get a page cannot be displayed. I checked that UFW was disabled and I am able to ping the motion computer from any other computer on my network. Also I am not sure if it matters but I do have apache installed on my motion computer as well. why I cant view my live video from different computers I am using Ubuntu 10.4 on all computers

I Have Ubuntu 9.10 Server installed and for some reason after updating our server with the ubuntu update manager, we can no longer connect to the network via remote desktop, let alone not even able to ping. We are actually able to connect to the internet itself just fine so I dont understand why this isn't working

I am trying to connect to a nfs server on my local network ( the server is a fedora 12 box ) using slackware 13.1 but I am having some problems. First of all I am sure that the server is configured ok and my desktop can ping the server but when I try :
mount -t nfs 10.0.0.1:/home/usr/file /home/usr/tmp I get the following error : mount.nfs: No route to host
And when I try to rpcinfo -p 10.0.0.1 I get the error :
rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host

Problem:Your company network has internal only hosts / websites with names that end in .local, e.g.Your freshly installed Ubuntu machine works fine on the network, has internet access, etc. but cannot connect to these particular systems.Testing DNS with tools like dig / nslookup works fine, but normal name resolution with ping / telnet / browsers does not work.Solution:1. Open a terminal window2. Enter the command sudo nano /etc/nsswitch.conf3. Change the following line:hosts: files mdns4_minimal [notfound=RETURN] dns mdns4to this:hosts: files dns4. Press Ctrl-X, Y, Enter to saveExplanation:Ubuntu ships configured to do name lookups for self-configuring networks, based on the AppleTalk / mDNS / Bonjour protocol. In the configuration shipped for the resolver, this protocol is considered the final aurhority for the ".local" top level domain, and DNS will not be checked. The above configuration change eliminates this and restricts lookups to (a) /etc/hosts file, followed by (b) DNS

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.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

I'm unable to connect to a particular home wireless network under Fedora 9, although I can connect to it using WinXP on the same machine. My Fedora installation is able to connect to my college's unsecured wireless network, so it's not a driver issue I think.It seems to be an authorisation issue, as I'll describe below, but there's one other thing that's bothering me. The SSID for the network I have problems with is for some reason not listed in Network Manager's drop-down list, nor is it in the output of iwlist wlan0 scan. But I'm pretty sure it's not a "hidden" network - I don't know exactly how those work, but I helped the owner of the wifi network in setting it up, and don't remember doing anything that would make it hidden. As far as I can remember, Windows found the network automatically without having to be told the SSID. What's the best way to confirm whether it's a hidden network or not?
Anyway, I try to connect by selecting connect to other wireless network in Network Manager, and entering the SSID. As far as I can tell from the error messages below, the machine does contact the network and attempt to connect, but I'm not authorising myself properly. That may be a completely wrong diagnosis, but hopefully someone can see from the below info whether it's correct or not.I'm not sure which option to use for "Wireless Security": at the time we set up the network, it gave us a Hex WEP key of 26 characters, which is 104 bits. But none of the options in Network Manager's list match that. Here are the options it has, and the error message I get with each one:None - if I select this, it fails to connect, with no error message.
WEP 128-bit passphrase - if I select this and attempt to use my 26-character WEP key, it brings up a new dialog, saying "Passwords or encryption keys are required to access the wireless network [SSID]." It has a drop-down box labelled "Wireless Security", but this time the only option is "None", and the connect button is disabled, I can only click cancel.
WEP 40/128-bit hex - as above.
WEP 40/128-bit ASCII - The connect button is disabled when I try to use the WEP key, as the string is too long. Despite the fact that it says 40/128-bit, it actually accepts 5 and 13-character strings (40 or 104-bit). Since I've got a 104-bit hex key, I tried converting it to ASCII, but it consists of mostly unprintable characters, so I'm not sure there's any way to actually enter it into the textfield. I might have done something wrong here, so I've put my code below to see if anyone can point out a mistake.
LEAP - requires a username, not applicable here I think. Windows doesn't need one, and we don't have one from when we set the network up.Dynamic WEP (802.1x) - requires username, private key and various other things, all N/A WPA & WPA2 Personal - Brings up a dialog with the same text as for "128-bit passphrase", but this time "WPA & WPA2 Personal" is the only option in the drop-down list, instead of "None". It asks for a password, so I just enter the hex key again - now it asks for the password for the Gnome Default Keyring, which I don't think I've ever set up. Don't know if I can go any further with that, but my understanding is that since we were given a WEP key when we set up the network, WPA will be N/A.WPA & WPA2 Enterprise - as Dynamic WEP. N/A.Hopefully that's enough info that someone can help diagnose the problem. Some of the behaviour of Network Manager described above doesn't make sense to me, and I'm wondering if it's buggy.

I see the network applet in the panel which shows that I am connected but I cannot access the net. I found out that I had to do this in firefox
about:config --> IPv6 --> disable.IPv6 true
With this tweak I was able to connect to the net. But when I use the Update Manager or Synaptic I am not getting connected, even if I use the cli and do

Yhe only ptoblem was that he had forgotten the password to his network. This was really anoying and has happened before sp yesterday i decided to install some kind of WEP cracking tool so that it would not happen anymore.. After using sometime without getting anything to work i found this tutorial: [URL]
and started following it. i only got to the point where he has updated his computer using update manager and is about to patch his wificard. Then i noticed that the network manager for gnome was gone and the virtualbox logo in my top panel was changed to a red circle with a line running through it. I have tried to download network manager from another computer and installing it on my laptop but it needs internet to install. Then i tried to connect to my local network using terminal that did't work either i also tried connecting using a cable but had no luck connecting. The command iwconfig gives me:

Just purchased a Dell Inspiron 580 MT tower pc with Windows Professional. However unable to connect to the network or the internet when I load a copy of Ubuntu Karmic on dual boot. Windows networking and internet working fine. Is this an ethernet adaptor hardware issue? Broadcom NetXtreme 10/100/1000 Gigabit Ethernet controller-PCI Express card Will try later connecting through a usb ethernet adaptor to see if this is really the problem.

I reported recently that I have a problem connecting to a Windows network, and someone suggested upgrading to Ubuntu 10.4 I have done, and still have the problem.
The error message I get is: "Unable to mount location. Failed to retrieve share list from server".

I installed 11.04 ubuntu 2 days ago. I have had thousands issues trying to connect to my wireless network router dlink di524. My wireless card is a dlink dwl g122 ver c1. I can't connect to the network no matter what configuration I try.
- first time i tried to connect i had static ip settled on my router so I tried to configure Network manager from GUI. I couldn't connect; it kept trying to connect forever. so I completely removed from terminal NM (using guides on internet) e installed wicd: same problem. Tried to configure manually network/interfaces file. Didn't work. Reset router and set dhcp . Tried everything again first with NM and then wicd. Didn't solve. Reinstalled ubuntu, fearing I messed up with some configuration files and reset again router. No solution
Tried pinguy os, zorin e linux mint . Nope Borrowed a network card from a friend after reading dlink dwl g122 could have some issues with linux. Tried this realtek card : same problems as above. Finally I tried again after the fifth reinstallation of ubuntu. Both NM and wicd keep saying wrong password. Changed different password. Password is fine of course (i'm using it now with win) So I Reset router password to none. Now it says: "acquiring ip address" and keep saying that forever. So i tried the last attempt: I tried to connect from zorin5 live to the same wifi network.. Ok so I happily reinstalled everything again (zorin5). first access after installation: same problems as above
Now I'm using win7 on the same wifi network, router, and same card (cards) and everything works fine at first attempt.

I have a network of 5 Windows Machines and 1 Linux Server. I created a Filemaker Pro Database on a windows machine and share it with the other machines through web publishing (only locally). - On any Internet browser, they only have to go the IP of the computer hosting the database - http://192.168.1.99:120 to enter & use the database, and all the other windows machines connect perfectly.
However, when I type the same IP(+port No.) into Firefox on my Linux computer, it can't reach the windows computer with the database (It just times out). Is there a firewall preventing it from connecting to other computers on the network, or do I need to update firefox or run another Internet browser or install Samba? I don't have much experience with Linux, as a programmer set the server up for me, so a simple solution with as little programming as possible would be fantastic.

I followed (or at least tried to follow) tutorials on doing this. I installed network-manager-pptp and tried to configure network manager to connect to a VPN. In the settings when I select MPPE with 128-bit encryption, after I've selected it and applied it, I check the settings and it's invariably unchecked. I tried using KVpnc after getting frustrated with network manager, and I can't seem to get that working either. I've been trying to search for info on this, and I can't seem to find anything on why I can't select MPPE with 128-bit encryption. That seems like it might be why I'm unable to connect to the VPN?

I have Windows XP with a gigaset adapter which connects to wirelessly to a Belkin router. I'm with Virgin Media.
I installed Wubi Ubuntu to try it out, and it all worked perfectly accept no wireless networks, not even nextdoors were listed.
It's enabled but it says it's disconnected. I have no idea what to do.
Is it recognizing my adapter?

I am unable to connect to any network, wired or wireless. Network-manager and wicd are both gone, as in no longer installed. Please don't tell me to apt-get anything. I have no network connection. I have tried downloading packages for nm onto a usb stick only to find myself in dependency hell which ended with the impassible error "Requires installation of untrusted packages".

Currently I'm having trouble connecting to the guest wireless network at my work. I've read through a couple threads that seem similar to my problem. I tried going through the terminal window and following the instructions that was offered to others. I'm just wondering if my hardware is different, if I need drivers, if my permissions aren't correct.
1. I recently received a Sony Vaio laptop model # VGN-FE770G from a friend, and I'm enjoying running Ubuntu.
2. I followed another thread that suggested to change some lines in /etc/network/interfaces, but I don't have permission to edit this file. I don't really have the need to set up multiple users on my laptop, so how can I change my permissions to root? (Or is it a good idea even?) Should I log in as root?
3. How can I set my laptop up to be flexible with network selections, using hardware: (built-in camera and microphone for example), and useful applications?
I ran "ifconfig -a" and this is what I got.

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

O currently have 2 USB WiFi adaptors: a Linksys WUSB54G v4 and a D-Link DWA-110. Both these USB adaptors worked extremely well in Windows: they could connect to any network: unsecured, WEP and WPA1/2I have tested these adaptors in DreamLinux, OpenSUSE and Mandriva: in these 3 distributions, i could use both adaptors to connect to my home's WPA2 network.Both adaptors also work well in Fedora 10.In Fedora 11 Alpha though, its a different thing: only the D-Link is able to connect to the home WPA2 network. My Linksys WUSB54Gv4 can 'see' the network, but when i enter in the WPA2 key, it takes forever to try to negotiate a connection before timing out and disconnecting.
