I messed up my Network Connections when I put a different NIC in my computer. Now I just went back to using the old NIC. It shows up in ifconfig, but the GUI Network Connections is blank. When I manually Add the connection back to the GUI Network Connections, the settings are not reflected when doing ifconfig.For example, I change the IP address for eth0 in GUI Network Connections, save the settings,

I recently installed fedora 12 in my server where I had a page published in my local net by tomcat, and I was looking on the Internet how to set up an static ip address and this is what I did
on /etc/sysconfig/network-scripts/ifcfg-eth0
# Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express
#
# File: ifcfg-eth0
[code]....
then I can access via ssh by two addresses the one I got from dhcp (10.17.148.223) and the static one (10.17.148.26) I put ifconfig and and 10.17.148.223 appear on eth0 I restart my server and I just can access from 10.17.148.223 I have to put
ifdown eth0
ifup eth0
Again...to access by my static ip, y can access my page by its dns on my server, but I cant access from other computer...so, I guess when my static adress appears on ifconfig I would be able to access my page from other computer...
I have windows 2003 server which i stored some important data that the workstation will connect it or access by thru network connection...
My current setup is: i have a linux distro i used mandriva 2009 and i installed samba...if i used windows to browse in network i can see the name of the pc of linux and i can able to access the linux shared folder.
My problem is if the linux try to access the windows 2003 thru network it seems to be nothing happened coz everytime i click the linux network it shows me a blank after a few seconds...
I really dont have idea if there is any requirements for the windows.
I really want to implement the linux workstation but i still have a big problem issue in networking.
My connection manager shows wired connections and shows wireless as being disabled. here is some terminal info getting wireless going?

I'm on Fedora core 14 linux. and I'm online with the HSPDA modem. My modem is /dev/ttyUSB0 and when it's dialed it creates the interface /dev/ppp0 , My question is when I hit ifcofig it shows two IP addresses in the ppp0 interface.
Code:
[nature@localhost ~]$ ifconfig

I have got Ubuntu 10.10 on a Dell Inspiron Laptop. Can't get anywhere with wireless network. Tried a few bits of poking it blindly with a stick:

I reckon *-network DISABLED is a problem, I tried sudo ifconfig wlan0 up but that didn't work. The output of that and lspci are on the ubuntu side of my machine. I have also tried pressing my wireless on/off key (F2) but that doesn't work either.
I have installed CentOS. I have two ethernet card (one onboard and one PCI). I am able to set ip for realtek ethernet card and my atheros(on board) is not shown in network ifconfig shows only one ethernet card (PCI) hen i gave the command lspci i got the following output

I'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.
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
once I updated , there will be no connections to Internet in GUI , while it's available in TUI . So it's wired , huh ? Before upating, it's available both in TUI and GUI, though all the time the network-manager shows no connection , in fact , there is and both GUI and CUI . Now I updated , and it can't access Internet from GUI.

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.
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

How to check Linux server network connections generally?
View 3 Replies View RelatedAll connections on my computer start loading and then hang: it happens when running apt-get update (a few repositories load successfully and then it hangs at a random one) and when loading web pages with the browser (it says "Connecting...", then "Waiting for....", sometimes some part of the page loads, and then it hangs).
This happens both with my wired and my wireless connection. It does not happen on Windows on the same computer.
Any idea on what it might be?
I have a bunch of Ubuntu boxes on one subnet, 192.168.1.0. I have a Windows 7 box on another subnet, 192.168.2.0. I am able to ping and SSH to all servers on the .1 subnet except for one server, which I will call PITA. I will attempt to SSH to PITA, and it won't respond, nor does it respond to pings. I will the SSH to PITA from another of the test servers, successfully connect, and then when I SSH from my Windows 7 machine I can connect successfully. If I first connect via console to PITA and send some pings out (to anywhere, like 4.2.2.2), I can also connect from my Windows 7 machine. I've never seen anything like this.
One of the weird things is that I used PITA to create an image that I then used to create many of the other test servers, and they work fine, so I'm not sure what the problem is. I've checked /var/log/messages and syslog and there's nothing in them that indicates a problem. I've rebooted this server, restarted SSH, changed the IP in case it was conflicting with something else, forced an ARP update in case it was cached (since I had bonded the interfaces), cleared the ARP cache on my own machine, verified Network Manager is not installed...and I still have this issue.
Here are some network-related config:

that open files value set to 1024, but is it valid only for real files ("file handles/descriptors" of files on your filesystems: hd partitions / cdrom / floppy / usb devices) or does it counts also network/sockets connections? i'm just asking without a reason. it's just curiosity ... as you can see sockets with lsof, somebody like me could think connections are counted as they were "files" by ulimit too
