I was struggling frantically this morning for about 5 minutes after I booted up my computer, and wondering why it couldn't connect to the internet. After I figured out that the automatic wired network "Auto eth0" was gone from the network manager, it was easy to manually add it back. But why did it disappear in the first place?
View 3 RepliesNetwork stopped working about a month ago. I installed ubuntu again, and network worked fine, and I turned off updates to keep things stable. Now network stopped working again. No changes had been made to it.I put in the ubuntu install cd, and network works fine off of it. I did not reinstall again. ifconfig shows eth0 with correct ip address, but 0 RX/TX packets.
Cant ping anything from it, and cant ping to it from other computers.I'd really rather not reinstall yet again, any ideas on how I should go about diagnosing this problem?Ubuntu 2.6.35-28-generic-pae #49-Ubuntu SMP Tue Mar 1 14:58:06 UTC 2011 i686 GNU/Linux
I just want to see if anyone else is having problems connecting to networks, wifi or wired. For some reason, I can see both wired and wireless networks available but when I try to connect, it times out. I updated a couple of days ago and suddenly started having problems today. Anyone else having the same problem?I have only tried the router and repeater I have to connect to. My other computers are working just fine. One is actually running as a Debian server with no GUI (which I do not update as often). The other is a Mac.
View 2 Replies View RelatedI woke up this morning to a message saying I have low disk space in /home. My /home partition is 150 GB, but I had only 4 kB left. I promptly rebooted, which helped, but I still only have 40 GB available. Now, I use only 26 GB, so where the rest is, I don't know. In the disk usage analyzer, a lot of the space was not accounted for, as shown in the image.

I've been an Ubuntu 10.04 64 bit user for one year. My Ubuntu distro is installed on an ext2 file system. Occasionally, I experience disk checks during boot without any system freeze or power loss.Sometimes, once reboot, the system works fine but Evolution Mail requests a new account, as if it was used for the very first time.Does anyone know how to fix this problem?

For no apparent reason, the server will just be powered off.I've looked in the dmesg log and /var/log/messages file, but that doesnt show anything, except the "syslogd 1.4.1: restart." message after booting it up again, and hours in advance of the crash a "suhosin" alert message.
View 9 Replies View RelatedI have just installed (after a series of crashes during the install) Fedora 15. I also have Ubuntu Natty installed and use it primarily but I wanted to reach out and try new distros.I've wanted to try Fedora and finally got enough nerve to try. Installing it crashed for no apparent reason several times.ehow it installed and booted right to Fedora.However, when finally figuring out how to run the updates, I began to have the same problem.(Someone elsewhere suggested trying to update through command line--which I did finally though I had a few crashes doing this).
Now I am logging in and then it will just inadvertently crash. I could be in firefox, or using terminal, etc. There doesn't seem to be much rhyme or reason to why this is happening and I feel frustrated. I really want to test out Fedora (it looks so nice!) but can't manage to stay afloat more than a few minutes. I might also mention that this does not happen in Ubuntu at all so I can't account for the issues. I have much to learn but I feel a bit intimidated by Fedora because it's so new to me.

When I go to my network connections, I do not see the eth0 at all. I have not made any serious changes lately and have no clue to what could have caused this. I have tested the cable with my laptop, and it works fine. I have serious reddit browsing that needs to be done!
View 3 Replies View RelatedAfter 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.
5.10 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).
I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all.

I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. 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.
View 3 Replies View RelatedWhen I installed Lucid I got temporary wifi connection. It disconnected for no reason. Then it was constantly trying to reconnect, telling me my password was wrong. Which wasn't wrong at all. So I installed Lucid again from scratch and now everything seems to work fine. The only thing I didn't do was install the 'restricted drivers'. This was only one driver for me which had to do with my modem. Wifi works perfectly now. I hope it stays that way .reinstall Lucid and DO NOT install the 'restricted drivers' for your modem

how to re-set the page numbers of a pdf file within evince (without modifiying the pdf file). The point is that I am reading an article, and I would like the set "page 1" as "page 43". modifying page numbers of a pdf file is a bit tricky. So, I want to avoid that. What I wanna do is to make evince "think" page 1 is page 43.
View 2 Replies View RelatedI have in my hand a CDROM with photos created by some greedy photographer. When I mount it I can see two files in there, two .exe executables about 7.7 MBs in size each. When I try to create an ISO of the cdrom, I get an IO error and only 16 MBs end up at the file.... so I would expect the photo files after the apparent EOF of the device (or whatever it's called in CDROM jargon).
