Since I installed ubuntu 10.04 I dont see my eth0 card in System->Preferences->Network _connections. Everything works fine but it puzzles me. In ifconfig iI just see the eth0, networking seems to be working fine, but it keeps puzzling me. Adding theinterface is no solution: add it and it doesnt show again
View 4 RepliesI recently setup a new SUSE box for the purposes of acting as an ftp/sftp server. It's currently setup to run ProFTPD 1.3.3.rc3 and mod_sftp/0.9.7. The server has two internal network interfaces eth0 and eth1. eth0 is purely for internal use to accept ftp and ssh. eth1 is outward facing and receives connections from the WAN via SFTP over port 22. The problem I am facing is that after half hour to an hour eth1 stops accepting connections whenever there is no SSH connection present on eth0. I can't figure out why this is happening.
ProFTPD is setup as follows: SocketBindTight directive is on, default server and port are commented out.
[code]...
When the external interface is unreachable the proftpd and proftpd-sftp logs show no record of any connection attempt. I have noticed however if I leave eth0 down eth1 stays contactable without problem. Can anyone give me some pointers on what I can check to find out why this may be happening.
I got two IP's in my dedicated server. Both are external IP's. I would like to make connections using 2nd IP address under eth0:0 interface. For example: when using "lynx whatismyip.com" should display my 2nd IP. How to do this using iptables ?

View 2 Replies View RelatedI'm trying to share some folders over the network, but the shared folders are not visible on another computer. This is through double clicking my computer from the Network list in Nautilus. However, I can access the share by typing the full address(<computer name>/<share name>) in "File > Connect to Server...".Since I can't type the address manually from my blu-ray drive, I need to get the shares to show on the network. What is wrong with my settings?
View 2 Replies View RelatedI've set up Samba under Ubuntu for windows SMB file sharing (currently unauthenticated but soon to be backed off against A.D.) This is great within Windows where l folders are available as mounted in all applications but from my Ubuntu desktop and Ubuntu laptops, we can only access network folders and files from the File browsers and bookmarks one finds in the "Places" menu. Our issue is that most (but not all) dialogue boxes don't have any options for viewing non-local files and folders. i.e. when I'm in my web browser and I go to upload a file from our local network file server to an internet location, the "Open" dialogue box cannot see any of our local network locations.
View 3 Replies View RelatedI'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
I am using Ubuntu 9.10 and I've installed a Samba Server. Unfortunately I can't see any Linux/Unix/Mac systems in the networ environment. Only the Windows computers are visible.
View 1 Replies View RelatedI have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).
My work computer, an IBM ThinkPad T43 running Win 7, connects.
My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.
I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system"
Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal
Why can I see the network but it is disabled/grayed-out?
hello guys, i had a problem regarding my network icon missing. two days a go it just work fine and I'm using this desktop pc almost 6 months with no problem.just yesterday the network icon suddenly disappear.I've put the notification area it doesn't solved my problem. well this is odd, because when I go to the terminal and "nm-applet" their the network icon appears from where it is and became visible BUT when I close the terminal/terminate the terminal it disappears. HOW CAN I PUT BACK THIS NETWORK ICON VISIBLE AND PERMANENTLY VISIBLE?
View 5 Replies View RelatedI am using Network Manager to connect to a VPN server so that I can access some of the computers on the local network there. When I'm connected, I have two problems: All my internet traffic goes through the VPN. My computer is no longer visible on my local network. I waste a lot of time connecting and disconnecting the VPN. Is there any way I can set up a VPN so that I am still on my local network and only requests to 172.x.x.x go through the VPN. I suspect it can be done with iptables, but all the info about iptables goes WAY over my head.
View 8 Replies View Relatedi have 3 comps(running ubuntu 10.04) and a laptop(running vista sp2). i have installed samba on all ubuntu comps. i have a printer attached to one of the comps and it has been shared also the internet connection on that comp has been shared. all the computers are connected using lan cables through an ethernet switch. i also have a wireless router which is connected to the ethernet switch.
I am able to view all the comps on the network except the laptop running vista. all the desktops are visible on the network and are able to print and share files on the network and also connect to the internet.the laptop running vista can connect to the internet but its not visible on the network and nor can it share files across the network or access the printer.all the systems have a static ip.
Neither of my wired network connections are listed in the network manager applet. I know that networking seems to be functional since I can ping local devices on the network. I can't resolve DNS names however. I suppose this is because network manager usually handles DNS? I've posted the outputs of various configurations below.
Code:
/etc/NetworkManager/nm-system-settings.cfg
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
View 5 Replies View RelatedHere is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:

i've installed ubuntu 11.04 on a friends Asus Eee pc 1005HA netbook. after the installation i tried to connect to the router using wireless, and when i enter the key, it fails to connect, so i tried using an Ethernet cable to connect but that doesn't work either,the network devices on the computer are:
Atheros AR8132 PCI-e fast ethernet controller
Atheros AR 9285 wireless network adapter
It lists the wireless device and the solutions to the problem, however, the solutions seem to be for Ubuntu 10.04 and also 10.10, and im not sure if it will work for 11.04 so far i have been unable to find out anything on the forums about the ethernet
So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,auto loiface lo inet loopbackBut I have a perfectly working eth0 connection. Why does not it appear here?

I'm having trouble running 2 network connections on an Ubuntu 10.10 machine. My wireless connection provides my internet access and is assigned the ip 192.168.1.7 My ethernet connection provides access to a separate network containing a nas box/server. The ip address for this is 192.168.5.100 When I am only connected to the wireless network, the internet works fine. However, once I connect to the ethernet network, I lose internet access via browsers and email client I cannot ping external web servers. It doesn't appear to be an ip address conflict so I'm at a loss as to what is causing my internet connection to drop.
View 8 Replies View RelatedI am total newby in Ubuntu 10.04. I have just installed it in my office where I have two networks card one connect to a router giving the internet access and the other connected to the windows based work network providing access to the work network sources. In XP everything works fine as I can keep both connections alive and have the results I want.
However although I don't know how to do it in Ubuntu 10.04. Till now I have setup the first connection directly to my router and I have internet access but I cannot set the other one. Another question is how I can force ubuntu to use the router connection as the default one when I log in.
Using xubuntu 11.04, how do I maually give myself a static IP address and other IPv4 settings? I see the edit connections panel and saved a setting there but can't see how to use that setting. The only useable setting when I'm connected by ethernet is Auto eth0.

View 3 Replies View RelatedI was browsing the net very well and without any issues for the past 15 days since I installed FC14. Fantastic experience and then suddenly yesterday after nearly 2 hours of a smooth online session I lost internet connectiivity.At that point I noticed that the network icon on top was showing a red cross. After clicking on it I could NOT eth0. I specifically remember seeing it there before.I checked the cables and the setting to no avail and just could not get it back. Any idea what I should be doing to see eth0 in the connection?Also FYI I have been noticing this from day one since I installed FC14----When going through administration-->network-->One cannot see the red and GREEN activate button that I am used to seeing in FC9. In fc14 its greyed out. So I actually had to go and enter the /etc/init.d/network start command to change the status from inactivate to activate.Also the network manager does not seem to be managing eth01 as it does not appear as an entry in its console.
View 1 Replies View RelatedUpgraded To Ubuntu 10.04 The Other Day. And when I first installed it everything worked great except for my sound card which I fixed. But there was no problem with connecting to my Router via an Ethernet cable. Then I updated the video card drivers, restarted my PC and it wouldn't connect. It would try over around 1-2 mins then tell me its disconnected. No green light activity on the router / network card either.
I've reinstalled fresh copies of Ubuntu a couple of times now, Hoping to get the default settings back. But nothing has worked since.
I looked around the net and found quite a few people had this problem on previous versions of Ubuntu but it would seem most of there fixes were for there Version, so it hasn't helped me.
Heres some info:
ifconfig:
I've tried all the various things from dhclient to ifup/ifdown etc etc.
