After a long time that I didn't touch my PC I just forgot how to configure the routing table I trying to ping the router and get "destination host untraceable" I manually assign the ip of the machine to 192.168.1.2 .And the gateway ip to 192.168.1.1 the only problem now
Is to get to the router interface on 192.168.1.1 to configure my internet and to browse
When I try wget URL... I get failed: connection timed out.I have created br0 as a bridge over eth0 to run this VM. The host has this IP 172.30.8.135.The host has access to internet through eth0 and this is the output of route inside the host.

Code: eth0[192.168.0.2] eth1[192.168.1.2] and eth2[10.10.165.2]
I am trying to ping eth0 from eth2, but I am not able to succesfully get a response from pinging the device, I am using:

I have tried to insert routing data into the routing table, but it still doesn't work
After making an changes (add/modify/delete) to /etc/static.routes, what command should we use to reload the routing table?

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)

A packet is sent from the computer to the router it's connected with only the destination address in it, right? So - what does "kernel routing table" mean?

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

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

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?

eth1 which is connected to interneteth2 internal networkbecause the server is part of a complicate network i need to setup the routing tables for eth1 and eth2but i need that the default 0.0.0.0 must be read from eth1 while i dont know why the server first read the one on eth2. this creates big problem to me.if i add the default route to eth1 i get an error saying that the default route already exist (i suppose is the one on eth2)how i can solve this ? i must create a script that first delete the default from eth2 and after add it to eth1

What exactly does gateway in a route refer to? I know what a default gateway is- it's the route of last resort. But used in context of a host route (with destination specified), what is a gateway and why is it important?

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.

I have recently upgraded a computer from Wheezy to Jessie, and I'm having trouble getting an internet connection shared via Ethernet by another computer (the provider) to work on it.I have activated the interface of the Jessie computer and configured a static IP on it in the same subnetwork as the provider's ethernet interface with the following commands:
Code: Select all# ip addr add 192.168.123.201/24 dev eth0
# ip link set up dev eth0
I now would like to set the address of the provider as the default route with Code: Select all# ip route add default via 192.168.123.100 dev eth0, but I get the following error message: Code: Select allRTNETLINK answers: File exists.
Indeed, when I run Code: Select all# ip route, the following comes up:
Code: Select alldefault dev eth0Â scope link
I've tried to remove this default route to replace it with mine with Code: Select all# ip route flush table main and Code: Select all# ip route del default but these commands don't seem to work.

I need to be able to do the following: Physical Router located at 192.168.40.1 On Ubuntu 10.04 Lucid machine:
eth0 with static ip 192.168.40.2
eth1 with static ip 192.168.40.3
eth2 with static ip 192.168.40.4
Associate a virtual address to eth1 with an entirely different network address such as 192.168.50.1 Do the same (virtual address) for eth2 -- e.g. 192.168.60.1 In the application:
register phone number A at 192.168.40.1 (The application will automatically use eth0 for this)
register phone number B at 192.168.50.1
register phone number C at 192.168.60.1
Somehow forward all traffic (including the register request) sent to 192.168.50.1 to 192.168.40.1 as if the register had been made directly to 192.168.40.1. In other words, the app "sends" registration and traffic to 192.168.50.1 but then Ubuntu forwards it to 192.168.40.1 (but the app does not know that). Similarly, forward all traffic sent to 192.168.60.1 to the router at 192.168.40.1.
Do the same for the reverse, forward all traffic that the router sends back to 192.168.40.3 (eth1) to 192.168.50.1 (within the Ubuntu machine) so that the app knows it is for phone B. Similarly forward all traffic that the router sends back to 192.168.40.4 (eth2) to 192.168.60.1 so that the app knows it is for phone C. Thus, the application believes that it is registering at 3 completely separate routers on 3 completely separate networks via 3 separate network interfaces but in fact is really registering all three to the same router (but does not know that). Similarly, the router believes that it is receiving 3 separate registrations because it receives each registration request and traffic from 3 separate interfaces and thus 3 separate mac addresses (i.e., of eth0, eth1, and eth2). Traffic sent to and from the router for each of the 3 phone numbers (via eth0, eth1, and eth2) are not mixed because the translation happens in both directions.

I installed FreeBSD on the empty space at the beginning of the drive. The slice I created did not start on the first block. There were a few MB of free space before and after it.
After the installation finished (with no errors), grub would hang on the "Grub loading/Welcome to Grub screen". I booted a squeeze CD in rescue mode and reinstalled grub to /dev/sda. After rebooting, Grub still hangs at the same place.
I booted a live CD and checked the output of fdisk. For each of my partitions, it says "Partition does not end on cylinder boundary". I am hoping that whatever happened to my disk is not recoverable. Fortunately, I backed up some essential files beforehand, but I still don't really want to lose my old squeeze system.
Right now I am fscking all partitions.
