I am running Ubuntu Server 10.10 still and I finally got a wired connection, but when I use the ifconfig command all I see is the lo(loopback) connection, and i don't know how to enable the eth0 port?

I installed the server version 10.04. The only problem with the install was setting up the network. I believe it was due to the fact that my nic was not setup correctly. The installation reconciled the nic, but upon the reboot after the install, I had no network capabilities. I tried to ping the router, no luck. ifconfig only showed lo. Also, the GUI (command F7) freezes and does not responds. The last thing shown is configuring web server. I tried to ndsiwrapp the drivers to the nic, but found out that ndsiwrapper is for wifi connections.

I would like to allow incoming and outgoing connections when I'm connected to a wired connection, but drop it otherwise. I noticed that ufw can't block outgoing traffic because of will I give iptables a try. I'm unsure if dropping packages that are outgoing will work, the rule after the block rule will allow all outgoing connections.
This what the rules are intended to do, unsure if that is actually the case. Allow all loopback traffic. Allow ping replys Allow incoming on port 12345 if eth0, deny otherwise. Allow outgoing on port 12346 if eth0, deny otherwise.
Code:
iptables -A FORWARD -j DROP

On Fedora 12 eth0 is disconnected (by the NetworkManager) by default until I manually enable it from GNOME. I need to make it connected even if I start my box in runlevel 3 or 4. How?

Yesterday I installed a RaLink RT2800 802.11n PCI on my squeeze system. Now I have a connection to Internet but I can not connect other systems in my home network. An ssh-try to a system in my home network results in: ssh: connect to host xxx.xxx.xxx.xxx port 22: No route to host If I use my eth0, I do not have connection to Internet, but I can connect other systems in my home network.

For about a year I have seen this issue during boot-up on Slackware, openSUSE, freeBSD, even windoze 7 reports issues in device manager.
This is a partial of dmesg:
I am unsure what is connected to port 6. I do suspect however that it is /dev/sdb
My reason for suspecting this is because I have been losing SATA ports on my MB for the past few weeks. I have 4 SATA controllers on the MB, first, SATA 1 died. Then today, SATA 3 died. SATA 1 was connected to /dev/sda and SATA 3 was connected to my other HDD /dev/sdb so I do not think this is a HDD issue. I have swapped out SATA cables, but that has not done anything to help. Today while fsck was running on /dev/sdb2 during bootup, the message: 'hub 2-0:1.0: Cannot enable port 6. Maybe the USB cable is bad?' kept appearing.
I am assuming this either means the HDD is failing or it is something to do with SATA controllers on the MB? But how can I tell? I have already lost two SATA controllers.
I have setup an OpenVPN server on my server box, it had been working perfectly until today. It operates on port 1194 which I am now unable to connect to (tried telnet). I have checked all the firewall rules and they still allow the port and I have also checked to ensure that OpenVPN is still listening to the port, which it's not but I have tried restarting the service and the box which dosent make any difference. The only thing that has changed is that yesterday I installed Openfire, could this have broken something?

View 6 Replies View RelatedI'm trying to enable port forwarding so I can use my computer as an FTP server to some friends. Here's my setup:
CLEAR wireless modem <--> LAN port 4 on router (not WAN) and LAN port 1 on router <---> eth0 in Ubuntu 9.10
The modem acts as a DHCP server which successfully assigns an IP address to my desktop system. I can also go onto the internet just fine on my desktop, and any other computer that connects to the router.
I have enabled port forwarding on the modem (not the router because it's being used as a switch, and not using its WAN port) to forward ports 21 and 80 to my desktop. What I don't understand, though, is that when I try to FTP to the modem's WAN IP address, the connection is refused. However, when I use websites such as:
www.canyouseeme.org
www.yougetsignal.com/tools/open-ports/
They say ports 21 and 80 are open (and not other random ports like 22 or 23 which I tried to see if the site simply said everything was open) but I cannot access my site from a web browser.
I was wondering what it was that's stopping computers from the Internet from communicating with my computer? The modem? The router? Configs?

Now before I begin I am running Openvpn on my CentOS VPS. I have set static IP's for everyone.
Now what I am looking for is this lets say one of my clients wants port 60005 forwarded through my VPS to the internet what are the correct commands to run.
server-ip:60005 to loacl-ip:60005
Sever IP 24.xx.xx.xx

After rebooting, I found that the server couldn't see the network. The machine has dual gigabit ethernet (eth0 and eth1). eth0 is connected to the internet, but disappeared. ifconfig used to show eth0, eth1, and lo, but now only shows eth1 and lo. If I boot into rescue mode I can get internet and ifconfig returns eth0 and lo. Any ideas on how to fix this?
I apologize in advance if I ask any noob questions. I'm not a very experienced Linux user.
I have three VMs (VMWare Server 2) all running Ubuntu Server 10.04. (one I asked to be a samba share from the outset, the others are blank server installs, no pre-config)
I follow the layout in the community documentation regarding setting up firewall rules through iptables. I.e. I create a file called iptables.rules and place it in /etc. I then modify the /etc/network/interfaces file to look like this:
Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo

However this third one I have reinstalled Ubuntu 3 times now, and every time as soon as I modify the /etc/network/interfaces file, eth0 fails to start up (is not visible in ifconfig, only the loopback adapter), and no networking works.
I have tried reducing the iptables.rules file (which is a carbon copy across all machines anyway) to a basic accept all rule, and it still doesn't like it. As soon as I remove those two extra lines in the interfaces file, the network starts up no problems and eth0 is there.
Just Installed Fedora 10 on Dell PowerEdge 2950. Installation went fine. Problem is I cannot Assign a Ip address to eth0. Service "NetworkManager " dies on its own "ifconfig eth0 192168.0.8/24" works though.

I've just setup Fedora 10 x64 on a Supermicro 7045 with dual nic; I setup a web site and ran into a strange problem; I can't see my website from outside my LAN; checking IP on Internet it sees my IP as coming for my dynamic IP (IP of router/switch) and not my static IP.
eth0: Static IP
eth1: Dynamic IP
These are standard Intel 82563EB Dual-Port Gigabit Ethernet Controller.
Is there a way to specify the order in which it sees the nic ports?
I'm wonder if I can mix Static and Dynamic IP's; on the outside they resolve to a static IP; the dynamic one shows up as my router/switch IP; but it allows me to access my DHCP computers; this isn't a web server; but a development machine for writing PHP apps.
Where 123.123.123.3 is my static IP address.
I should mention that nmap -v -p 80 123.123.123.3 shows an open port on 80
My VirtualHost is setup like:
The problem is that samba shares files easily on eth0 while on eth1, every file gives a read error.

I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?

View 7 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?
