building a box with no other interface than tcp/ip. now in case something goes wrong when changing the /etc/network/interfaces via ftp and when rebooting the system cannot bring the interface up I would like to be able to detect it and replace the interfaces file with a default one stored on the system.
View 1 RepliesMy Question is I have installed the ssh key authentication in Server A. User can connect this using key file via SSH. without authentication user can't connect this system via SSH. Now I am trying to copy the file from Server B through SCP command. But it is not working. While I am trying use this command from Server B I am getting below error "ssh: connect to host xxx.xxx.xxx.xxx port 22: Connection timed out lost connection". xxx.xxx.xxx.xxx is Server A. SSH is enabled in both server A,B.
why SCP command is not working?
Im a new member here.So please don't get mad at me.If i posted on a wrong section(Am I in the right section?) By the way,Here is my problem. My graphic card is Intel 82852/82855.And it passes the Ubuntu Desktop Effects requirement. I am aware of enabling the graphic card in Ubuntu 10.10, Since enabling the drivers was successful. I enabled the desktop effects.After i switched to Normal(Graphic Mode)the screen went blank. Then after i clicked ALT+TAB. there is an option to keep this option or not.I clicked Keep this settings. Then i proceeded in Web browsing(because i'm a web addict). Then i click CTRL+ALT+LEFT/RIGHT For the workspaces to switch. Then i found this 4 square transparent with black margin boxes.Which has a weird distorting effect.That effect is going crazy. Then i rebooted(Hoping to fix the problem).Then it is still there.
View 1 Replies View Related5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?
I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).

The startup and shutdown displays are a series of vertical black and white lines, and the text displayed on them appears as more or less white blobs. Otherwise, the displays when 11.04 is running are fine, but this startup looks so naff it would be nice to change it so that the diplays can be read. I would hate to demonstrate Ubuntu to someone and have to explain such a display.

Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.

I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.

However, I came home this week to my mothers house, where they have a dsl-router to connect to the internet whih uses bridge mode pppoe. I tried to connect to the internet through it, and it initially couldnt. However, I got around that by doing a clean install of ubuntu. I was able to then connect to the internet using "sudo pppoeconf" and "sudo pon dsl-provider"One night the network manager app on the top left disappeared and would not come on. I figured I had fried my wifi adapter, however, lspci -v confirmed its presence.Further, "system>admn>system testing" detected the adapter aswell.

i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
On my machine (Desktop PC) I have 2 network card : wireless (rt61 802.11) and a wired card (BCM44). When I install debian 5.
The wired card is detected and logical name eth0 is assigned, while wireless is not assigned I install firmeware* software to configure the card. It is done in some way ( I used mnetwork from mepis, it works fine).
Now the problem: eth0 disapears, and no eth0 inteface found? ifconfig gives just wlan0.
Question: Why there is no eth0, it was before configuration of wlan0 ?
How to active again eth0, or ho to create the logical eth0?

How can I start dhcpd after Network manager has set up a new connected device. The reason being that dhcpd will not start when there is nothing connected to the network interface. Therefore I would like dhcpd to start after a new device is connected. Now I have found references if ifup-post but this does not relate to NM, is this correct?
