I`m relatively new to Linux and Ubuntu.Now I have been playing around, editing the settings files for the networks cards, and now I have messed things a bit up.Any way to delete all settings, and make Ubuntu autodetect my hardware again?
View 3 RepliesRecently, I had the courage of installing Fedora 11 on my laptop while risking of trashing my Windows XP. Fortunately, the installation went fine and windows and fedora seems to be working together. But I needed to reinstall Fedora because I didn't do the partitioning right. After that the problem arises. I couldn't connect to the wlan. The first installation it was working fine. Now I can't. I select the network, enter the password and then it just says "Disconnected" or something like that then nothing else happens. So I had to reinstall it again thinking I did something wrong on the installation. But still it wasn't working. But it seems to be working when I boot from the live cd. I must have messed up my network configuration.

I tried downloading the original network manager deb packages from the ubuntu archives, but I couldn't get the core application to run (though I could get the GNOME applet) even wtih chmod I didn't have permission to do anything with it.
I am trying to get my ethernet adapter list to make some sense. This is what ifconfig spits out
Code:
agarzon@euler:~$ ifconfig

the default for /etc/network/interfaces? I believe I screwed it it up because I can detect my wireless, it just won't allow me to connect to it. The settings in the /etc/network/interfaces are all messed up. I'm running Ubuntu 9.10.

I clean installed xubuntu on an old laptop. I think I messed up the original configuration of xorg though because the highest resolution is 800x600.

I recently installed Fedora 11 on my machine, the configuration of which is: Intel Core i7 920 CPU, 3 GB DDR3 SDRAM, nVidia GTX295 Graphics Card. I initially used the default kmod-nvidia driver, but with a yum update, somehow a non-PAE kernel got installed and the kmod-nvidia driver did not get installed with it during the update for some reason. So I uninstalled the PAE kernel and associated kmod drivers, and downloaded the nVidia driver from the nVidia website. It ran just fine for a few days, and then all of a sudden, after a reboot, the X Server crashed and I had to log into the text mode, run
Code: setup and do the default X configuration. Then, I re-installed kmod-nvidia, with no luck. Sorry for being so vague about this, but I finally managed to get the CUDA driver (I need to use CUDA for my project work) to work (downloaded from [URL]). But after one reboot, the same problem resurfaced.
Now, I am in X Windows with a default 800x600 configuration using a generic visa driver, on a 23" monitor I have been rebooting my computer all morning and trying various things to get the driver to work again. I would be happy to furnish any details about the installed packages I have. For now, here is some information.

View 1 Replies View RelatedI have my new router all set up, and everything is working fine, but I'm having problems adding a password to the network.The network from the wireless router is called "auto dlink" by default, and I've tried through the Gnome interface to add a WEP 40/128-bit key that I generated through a website. As soon as I apply the change to the network, the connection drops, so I click on the "auto dlink" network again to connect, and it successfully does, but it never asks me for the key that I configured it to ask for. After checking the network connections history, it shows me as having connected to two different "auto dlink" networks at different times - the one that I added the key to, which is no longer available, and a new one that I am currently connected to, that does not have a key. Every time I try to make a change to "auto dlink," be it a change to the security or to the network name, the change registers and applies, but the network ceases to be available and is instead replaced by a new, default configuration of "auto dlink."

View 5 Replies View RelatedThe other day I was using BitTornado and it was running so slow it was almost unholy. After some research I found out that if the yellow light was on it means I couldn't receive any incoming connections and had to open some ports on the firewall. That, my friends, is not the problem. I tried to manually open up the bittorrent port and did some other things that I can't quite remember but eventually I accidentally killed all bittorrent functionality on my laptop.
Is there any way I can reset my network and ports back to the default settings or am I utterly screwed? I'd really prefer not to have to reinstall my whole OS just to fix my bittorrent or worse, have to download on Vista *shudders*. I'd rather go back to my uber-slow bittorrent than none at all. I've tried everything I can think of, even the godlike might of Google couldn't get me out of this one. Now I am forced to bother you, all because I wanted to see a damn sci-fi film from Switzerland (Cargo[2009]).
For Ubuntu 10.04, I can configure the network by "Network Connections". This configuration is done by doing the following operation sequences(System->Preferences->Network Connections->wired->auto eth0). Then I can connet to and browse the internet. If I type the command "ifconfig", I can see the ip I configured for eth0. Part of the content is as blow:
Quote:
ifconfig
eth0
inet addr:192.168.28.31 Bcast:192.168.28.255 Mask:255.255.255.0
But in the "interfaces" file, there is no eth0 content. The whole content is simply as below:
Quote:
cat /etc/network/interfaces
auto lo
iface lo inet loopback
I think there should be other files that keep the eth0 configuration content.

Based on what I understand, eth0 goes to monitoring and the other 2 ethernet cards go to FE. I am not an expert in system administration but would like to know if there is any issues with the above settings/configuration (in fact, im also looking for what do they infer and what is the settings?
I'm a Linux n00b (very fluent in Windows, though ) that is attempting to set up a (currently) 3-computer cluster. My server node is a Pentium 4, and my client nodes are a Pentium 4 and a Pentium 3 (whatever I have lying around ) I chose to use OSCAR for my clustering interface and CentOS 5 for my server node OS. Yay. I made it through the installation prerequisites, but when it came to configure the NIC, I got stuck.
I opened the /etc/hosts file, tinkered with it, but something inevitably got screwed up. I can still use the Internet, but it won't let me install OSCAR. Running a system-sanity check returns:
Code:
[root@SurgeonfishR ~]# system-sanity
Checking your system...
Success: ssh-check.pl
Success: tftpboot-check.pl
Success: selinux-check.pl
[Code]...
All I need to know is what the /etc/hosts file should look like for a CentOS 5.4 installation with 1 NIC that is not connected to a domain (only a LAN). It is connected to a router which in turn is connected to my home network (I don't know what to do about that). The hostname should be surgeonfishr and the IP address should be 192.168.0.150.
I know this question is probably really stupid, but I've logged a total of about 10 hours time on Linux...ever. (And 35000 hours on Windows.)
I want to create a small network of 3-5 computers. I want to have one computer as my server and have services like NFS, DHCP, NTP, etc. I want to connect it to 2-4 other clients that have the bare minimal installation of linux on them. I would like 1 client computer to have a static ip address and I would like another to receive a dynamic ip address from the server. How would I go about doing all of this without the assistance of GUI's? I want to be able to do all this with the ks.cfg and network config files.
View 4 Replies View RelatedSimilar to the linux command "chattr +i filename", I would sure like to set my eth0 interface immutable. so once I assign the eth0 interface's IP and gateway, make it stay set until I say otherwise.
this way, I can run dhclient or Networkmanager on another interface without having to fret that it may alter this interface. is there something out there that can do this?
I have three 10Gb Fibre PCI ethernet cards and 2 onboard gigabit ports. The two gigabit ports always seem to be mapped to eth0 and eth1. I set the network configuration for eth2, eth3, and eth4 in the /etc/sysconfig/network-scripts/ifcfg-eth# files. Would the NIC in PCI slot 1 always be mapped to eth2, NIC in slot 2 mapped to eth3, and NIC in slot 3 always mapped to eth4?

As the UMW190 is a 'World' capable mobile Broadband adapter is has both CDMA and GSM capability. I only need CDMA for now. However, when network manager detects the VZ UMW190, it does not offer Verizon as a choice in the Provider list. I searched and found references in this forum for using the UMW190 under 9.10 with gnome-ppp via this link:[URL]and tried it without any luck.I have previously used a VZ UM175 on this machine under 10.04 without any issues as Verizon appeared in the Provider list and the configuration worked without a problem.

For my router I need to change Ubuntu server from DHCP to static IP. So to do this I entered: Code: sudo vi /etc/network/interfaces ...and pushed the wrong buttons and exited the session suddenly by mistake. After learning how to use the vi editor I went back but I got a notice that the the last session didn't close properly and that a "swap" file had been created. Anyway, I entered my static IP info, saved the file, and attempted to restart with:
Code: sudo /etc/init.d/networking restart Restart failed and I got a notice that I should delete the /etc/network/interfaces.swp file so I did. Tried to restart again and, didn't get the .swp file conflict message this time, but failed again - this time I got the following message:

This may fall under the "ain't broke don't fix it" category but it's driving me nuts. I've got the Broadcom 4322 wireless adapter in my laptop and it works fine with broadcom-wl driver and kmod. However there is no ifcfg-eth1 file and the card does not show up in system-config-network.

View 4 Replies View RelatedI'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.
