Networking :: IP Routing WirelessLAN And Ethernet In Same Network

Feb 1, 2010

My hardware has two interfaces: a) ethernet - eth0 b) WirelessLAN - eth1.After power on, eth1 gets associated to WirelessLAN access point.

The ethernet interface of Hadrware and test PC is directly connected to Wireless LAN access point through ethernet cable. Hardware is associated to Wireless LAN access point through eth1 interface.Now, when ethernet cable is connected to hardware, I can ping 192.168.254.254 from test PC.When I removed ethernet cable from hardware, I cannot ping 192.168.254.253 from test PC.I think access point should forward the incoming packet from test pc to hardware's eth1 interface wirelessely. Where am I wrong? Is it related to Kernel's routing table? If yes, how to detect removal of ethernet cable from hardware and change routing table dynmically?

Networking :: Routing To Internet Through One Network And To Local Ips In Another Network?

Mar 31, 2009

I have two networks. One of them is wired, the other is wireless. The wired has an internet connection and a few other computers connected to it. The wireless network has a few hosts connected to it too, but it has no internet connection. What I've been trying, fruitlessly, to do, is make all connections that are bound to the internet, or my wired network, be routed that way, and all the connections to the hosts of the wireless network go that way.

Here's the setup..

Wired:

192.168.1.0/24 Gateway = 192.168.1.1

Route internet through here

Wireless

192.168.2.0/24 Gateway = 192.168.2.1

If my computer sends a packet to the internet, it should be routed through 192.168.1.1 If I send a packet to one of the local hosts of the wireless network, it should be routed through 192.168.2.1. Here's the routing table I've set up(This is one of many configurations I've tried)

Code:

$ ip route show
192.168.2.1 dev wlan0 scope link
192.168.2.0/24 via 192.168.2.1 dev wlan0 src 192.168.2.4

[code]....

With this, and everything else, I get destination host unreachable when pinging. The strange thing is that, if I unplug my eth cable, reboot and connect to the wireless network, everything is fine and I can access the router and the others. I'm trying to improve my networking skills, as I've had this of setting up a small linux box as a router for quite some time, for the fun of it, but I need to get routing under control before I go ruin my network.

Networking :: Iptables Routing Packets On Same Sub-network

Feb 17, 2010

I am running into trouble while trying to set-up a iptables routing policy. I have two machines on the same sub-network (xxx.xxx.153.0). One of the machines is used as a default gw for the other (xxx.xxx.153.250 is a gateway for xxx.xxx.153.142 and xxx.xxx.153.254 is a gw for xxx.xxx.153.250). There is no explanation for why the xxx.xxx.153.250 is in the middle -- xxx.xxx.153.142 can go straight to xxx.xxx.153.254, but is is like that for now.I am trying to find an iptable rule to be executed on the xxx.xxx.153.250 machine to route the packets.

Networking :: VPN And Routing - PC No Longer Visible On Local Network

Aug 26, 2010

I 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.

Ubuntu Networking :: Erroneous Routing When Both Mobile Broadband And Wireless Network Connected

Mar 30, 2011

I have internet access using mobile broadband and i also have a wireless network for home usage without internet access.

When my wireless network is connected every application in ubuntu (Meerkat) tries to use it for inernet access (as neededobviously). As soon as i disconnect from the wireless network (and assuming the mobile broadband is on) everything has access to the internet again using the mobile brodband.

How do i tell ubuntu that i don't want it to use my wireless network for internet access?

Ubuntu Networking :: If Plug Into An Ethernet Network After Boot The Network Never Connects

Oct 5, 2010

I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,

cups cupsys ssh pi memtester nfs-common
aptitude safe-upgrade

At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.

This is used for a headless(no monitor, no keyboard) system running some custom applications.

Here are two problems.

1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?

2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:

Code:

However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.

/etc/cups/printers.conf has been wiped out to look like this:

Code:

My 'good' printer configuration is copied to printers.conf.O

To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.

So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.

Networking :: Why Ethernet Is Used Only In Local Area Network?

Dec 25, 2010

One question that weight a lot of points was about ethernet... the professor asked why ethernet is used only in local area network? resuming i wrote that ethernet is used only in LAN because it is shared and so for big network there could be a lot problem in using the shared channel.. for istance using protocol such as CSMA/CD, if a big network has a lot of hosts, they could wait a long time before sending...is it right or am I wrong?

Networking :: Can Use 2 Ethernet Cards For Green Network In Ipfire?

Jul 5, 2010

Ok, so I've gotten tired of my router, and I've decided to make my own using IPFire as the OS. Right now I'm looking for ethernet cards that I can use for the green network, but I don't know if I can use 2 for the same network. I'm trying to get 4 ports at 1000 Mbs, and the only thing I've been able to find so far that's within my price range is a card from startech that has 2 ports, but would I be able to use 2 for the green network?

Ubuntu Networking :: Use 3G USB Modem Dongle And Ethernet Network At Same Time

Feb 24, 2010

I currently have a computer sitting underneath a router/switch on a Local Area Network that I want to connect to the Internet using a 3G USB dongle modem. If I am connected to the ethernet and then enable the modem connection, only the ethernet LAN side works. If I enable the modem and then enable a (disabled) ethernet connection, only the ethernet LAN side works. If I keep the ethernet disabled and connect using the modem, I can get out onto the Internet, but obviously not the LAN. I need to be able to do both.

General :: Set Up Routing Over Two Network Interfaces

Sep 9, 2011

I'm often on my corporate network but also need to be on another network simultaneously. At the moment I have to manually switch back and forth between the two. I'm using ubuntu 10.04. I've come across an excellent document that explains how to do this: "Linux Advanced Routing & Traffic Control HOWTO" by Bart Hubert. He mentions:

make sure that your kernel is compiled with the "IP: advanced router" and "IP: policy routing" features

I've downloaded the kernel sources, but I don't find any config options with names like these in them.

sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
sudo apt-get source linux-image-$(uname -r)

Searching doesn't reveal anything

~/kernelBuild/linux-2.6.35/debian.master$ grep -iR policy . | grep -i routing
~/kernelBuild/linux-2.6.35/debian.master$

So my question is...how can I tell if the kernel I have has these config options. Failing that, how do I build a kernel that does support these things?

Additional use cases for this knowledge. (1) At work with desktop computer plugged into corporate network. Plug 3g phone into USB port. My corporate network wont allow me to access my external servers over ssh, but the 3g phone will. (2) At home on the corporate VPN, but would like to access my other local network computers.

OpenSUSE Network :: Configure My Server For Routing Between Vlans ?

Jul 29, 2011

I'm trying configure my server for routing between vlans, but I'm having troubles with my server after that vlans are set. I can create vlans and routing is OK, but when I trying remove a vlan, restart the network script or restart the server, the CLI freeze and then I can't do anything. Even Ctrl+C or Ctrl+Z isn't work. I can use other terminal or do other SSH connection (if the network interface used by ssh isn't crashed), but if I try use a ifconfig per example, crash again. The unique solution is restart the server. Nothing about this is found in the log.

Server :: Multiple Network Zone - Firewall Routing

Mar 29, 2010

We have a 10.0.0.x network with a working DNS Server (BIND) setup. Recently we purchased Watchguard firewall and configured three networks, so that our internal network can be divided into three networks and talk to each other through firewall routing. So I configured three ips 192.168.0.1,172.16.0.1 and 10.0.0.1 for local network card in the firewall router. I separated three networks and individually configured machines with static ip and given gateway as the above ips. Now, I need to configure DNS server for each zone in the same server which is in the network 10.0.0.x, is this possible?. If yes do I need to setup ip aliases for eth0 in the DNS server with different ips from each network?

OpenSUSE Network :: Create Network Bridge / Device Hooked Up Via Ethernet Had No Internet Connectivity?

Feb 25, 2011

I'm on opensuse 11.4 (11.3 won't work with my monitor).

My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.

I also tried this command:
echo 1 > /proc/sys/net/ipv4/ip_forward

but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?

Ubuntu Networking :: Broadcom 4401 Ethernet: No "Wired Connections" Showing Up In Network Manager?

Apr 10, 2011

I've been struggling with this a bit now, and I'm not sure what the problem is. I have a laptop with a BCM4401 Ethernet card as well as a BCM4311 Wireless card. The wireless card works great out of the box, I'm able to connect with it perfectly. The problem is the ethernet card. Here is the situation: The NetworkManager menu doesn't list "Wired Networks" at all (ie. it doesn't say "not managed", it just only lists Wireless networks) Going into Network Connections, there is an "Auto eth0" entry ifconfig shows eth0 (which I assume means NetworkManager isn't managing eth0) I have edited /etc/NetworkManager/nm-system-settings.conf to say managed=true I have edited /etc/network/interfaces to remove any mention of eth0 (all that's left is the "lo" lines) So I'm not sure why eth0 is still showing up when I run ifconfig, and why Network Manager is not managing it. Any ideas?

Edit: Not sure what I did but now ifconfig spits out this:

Code:
eth0 Link encap:Ethernet HWaddr 00:1c:26:2c:60:75
inet addr:10.0.1.12 Bcast:10.0.1.255 Mask:255.255.255.0
inet6 addr: fe80::21c:26ff:fe2c:6075/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

[Code]...

The MAC address of the "Auto eth0" entry is 00:1C:23:8F:D4:39, the same as the eth1 entry that ifconfig spits out.
