Networking :: Routing Table For 2 Servers?

May 18, 2009

routing tables using "ip route 2" I have a server(server1 from now on) with eth0(internet connection) and eth1(lan connection). eth1 have 2 more alias devices = eth1:1 and eth1:2 On my server 1 the eth0=public ip, on eth1=192.168.10.1/24, eth1:1=192.168.20.1/24 and eth1:2=192.168.30.1/24 server1 is running squid and iptables to all 3 networks (eth1, eth1:1 and eth1:2) All of the clients have access to internet. Now what i want to do is add 3 more networks via a router(linuxBox = server2 from now on) connected to server1 in eth1. so the network will be like this:

Code:

server1
eth0=internet
eth1=192.168.10.1/24 (connected to server2 and other clients)

Ubuntu Servers :: 9.10 - Routing Table Getting Corrupted

Jul 25, 2010

I have an Ubuntu 9.10 server installation which have been working flawlessly for some months. The server runs bridged networking, because of some VMs that runs on it. But, a couple of weeks ago the network connectivity have started to disappear now and then (usually once a day or so). Running "sudo /etc/init.d/networking restart" always kicks it back to life.

After a bit of debugging I noticed that when OK the routing table looked like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 br0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
default 192.168.1.1 0.0.0.0 UG 100 0 0 br0

While when in the non-working state it looked like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 br0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
default 192.168.1.1 0.0.0.0 UG 100 0 0 eth0
default 192.168.1.1 0.0.0.0 UG 100 0 0 br0

Deleting the two routes to eth0 restores the networking again. Why these "erronous" routes gets added, and what adds them? How to further debug this?

Networking :: Restore Back The Default Ip Routing Table?

May 16, 2010

Is there any way to restore back the default ip routing table? For example, my current routing table is something like

Code:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
109.123.95.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 109.123.95.1 0.0.0.0 UG 0 0 0 eth0

Then i connect to a vpn service and the routing table get's changed..now when i close it, it doesn't reset back to my default routing table.

OpenSUSE Network :: Hostname Not Saved In Router Table / Broadcast It To Entire Network?

Jun 13, 2010

I setup the hostname for my linux machine to Linux. If I try ping Linux from the same computer it works. If I try from another computer inside my network the host can not be resolved. If I ping the IP from another computer it works.

I take a look in my router at DHCP client list and my linux machine doesn't have the Hostname set up.

How to broadcast the hostname to the entire network?

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.

OpenSUSE Network :: Routing From Host To Vmware - Server - Guests

Oct 30, 2010

I just installed (n this 11.2 system) vmware server (v 2.02), to have access to a few small systems. One of them is a 11.1 guest which I just upgraded to 11.3, successfully (almost).

I have a problem, though: from the host I can not ping/ssh the guest.

Guest to host works fine (including names).

Code:

The firewall is down on both sides. I don't see anything with iptraf in the guest. The IP addres of the guest is correct, unless I'm too tired to see.

Why?

OpenSUSE Network :: Complete Freeze When Downloading Torrents?

Apr 16, 2011

I'm experiencing complete system freezes when dowloading torrents with more than 800kb/sec (I think this is the limit, I've capped it at 750, and it seems to be running ok now). I had this same problem in Ubuntu aswell. But not in Win 7. The problem also appeared in ubuntu when streaming video through VLC with more than 800kbps.

As my connection gives me quite alot higher download speeds this kind of annoys me, and me being quite new to this whole Linux thing, don't really know what to do. I had a dialogue with someone at Ubuntuforums regarding this, but we pretty much got nowhere.

I have an ASUS 1201N laptop, with ION chipset.

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.

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.

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 :: 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.

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?

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?
