Ubuntu Networking :: How To Reinstall Network
Nov 14, 2010
How can I reinstall network. I remove dhclient3 because chkrootkit identified it as a possible issue. Well, now I have no internet. I am running from the live cd for ubuntu right now.
I was told to copy files. I tried to copy files but was unsuccessful. I did not see 'dhclient3'.
Is there a way I can reinstall the all of the network part for ubuntu?
I can just reinstall all of ubuntu, but I have some pictures on the drive now that I do not want to lose. Also, unfortunately, I do not have enough storage as I am out of dvds and the usb drive I have is too small to hold all the movies that we recorded with the digitial camera.
I installed SELinux, Chkrootkit, ClamAV, AIDE, and set up UFW firewall. I wrote it all down, so I can do all of that again if needed. I just don't want to lost my videos / pics.

I am using Ubuntu 10.04 LTS 64 bit. I deleted network manager so that I could install wicd but did not install wicd first so now I have no internet. I have read several post and the answer for me is not there.

I have a newly installed CentOS 5.4 on Gigabyte G31M-ES2C, I had to change the motherboard since it has some problems. Unfortunately the new motherboard is a rev 2.x board, which has a different onboard NIC (old one is RTL 8102E, new one is AR8132), so now my ethernet connection doesn't work anymore (no eth0 device), I assume I need to install a new driver for the AR8132? If so, what's the steps to do so?lspci shows Ethernet controller as: Attansic Technology Corp. Atheros AR8132 / L1c Gigabit Ethernet Adapter (rev c0)

This was working for me in 10.10 until I was forced to reinstall Ubuntu. I have a Western Digital Live Hub, basically a hard drive that sits under my telly and lets me stream media from the computer or transfer media to it from the computer. I could access it fine a couple of days ago, but then I reinstalled Ubuntu and now I get the error "Unable to mount location, Failed to retrieve share list from server". Anyone have any idea how I can access it again?

I was trying to configure a wireless network for my pc and it ended in a mess and now I dont see anywhere the wifi icon (yes, I have already tried "add notifications")
The thing is that it seems the whole network manager is not longer there
I have downloaded the package to reinstall it (Im writing now from a friend's pc) without sucess, because network manager needs other packages who are supossed to be downloaded from the internet while the installation, but I do not have Internet!

I can't get my wlan running, although it already worked on my notebook (Dell Inspiron 1545) with opensuse 11.1. Then I installed debian and, I don't know how, it changed my kernel in grub from .pae to .debug (renameing in grub didn't help)
According to the messages scanning fails
My wlan-controller is:
Router is avm Fritz!Box and is working fine with other notebooks and the lan of the Dell
I loaded down and installed the driver from Bradcom (hybrid-portsrc-x86_32-v5.10.91.9.3.tar.gz)
dmesg came up with a failure: not ipv6 server found - so I deactivated it
Below find further info:

So I was messing around trying to uninstall Nibbles and reinstall since I have an issue starting that game and something happened and removed the submenu under Games called "Logic", which had another whole list of games.
Is it possible to reinstall the games package or reinstall the update?I'm thinking more of the lines of a system restore or something so back 2 days from today.

I gave up trying to figure out the problem and just reinstalled 10.10. Anyways, did the reinstall, installed all proprietary drivers and STILL NO WIRELESS. Seriously, what the heck is going on? Again, computer is HP Pavillion dv2500, using 10.10, and the wireless driver is the Broadcom 802.11 Linux STA wireless driver. I previously had access to the Internet, so I really don't know what could have changed.

I did a few things to the drivers and the wireless aspect of my ubuntu system and I'd like to know how would I reset everything back to as if it was a fresh install (but only regarding my wireless drivers and all that jazz)?
I'll have to purge it and then reinstall it over a wired network.

I've been searching forums like for 2 days, but couldn't find any similar problem.
First of all im running Ubuntu 10.04 desktop version on my netbook Acer aspire one (AOD150)
Every time i turn off my netbook and after turn it on, in "Hardware drivers" it says that driver for wifi is not in use, also button for switching on/off wifi is not working.
So everytime i start up i have to go into "Hardware drivers", remove driver for wifi, and then activate it again. And everything is working gr8 after. Its just too annoying to do it everytime.

I recently upgraded Ubuntu 9.10 to 10.04 and my wireless stopped working. It can detect that there are networks around, what their signal strength is, and then try to connect to one, but it just keeps connecting. After around 5 minutes, this stops and nm-applet says no network connection.
After I try to connect, dmesg is spammed with hundreds of the same message. I can not post these here, as I am writing from a different computer and I have no internet access from my main computer.Also, there is nothing in interfaces.conf other than lo. For some reason, my card is referred to as both wlan0 and wmaster0, with this changing depending upon where I look.Most interesting of all is that, even after I reinstalled 9.10, wireless is still broken, even though it wasn't before. It also used to work under liveCD.

I recently reinstalled 10.04. The wireless worked fine for a week or so, but not it cant get a connection for more than a few seconds. Ive downloaded Wicd, and after an eternity of trying to connect, it tells me that no IP address could be established. I can connect no problem when I plug in via Ethernet cable. Nothing when I try to use the wireless though.

After reinstalling Ubuntu, I cannot reach the windows computers (both on the MAISON workgroup). Since I have not changed a thing to these two win machines, I assume something is wrong with my Ubuntu config.Samba is installed and running (or so it seems). Dolphin shows the Samba shares, but give this errormessage:Unable to find any workgroups in your local networkthis is the testparm output :
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

I have a windows XP Pro machine and also a Server running ubuntu, the server was built for me and the builder is no longer available for consultation. The server drives which were on my desktop beside my C drive were working flawlessly allowing me access until windows started running quite badly which meant I had to reinstall it. After the reinstall I could not see the drives displayed and I am unable to access them from windows. And also not able to mount them. The server has not been switched off at any time and does not even have a monitor or keyboard or mouse. I have not done anything to change any settings to it. I have zero knowledge of the system. My windows administrator password is exactly the same I have looked on the server and my files are intact I just cant access them from windows which I need to do.
I got the following details off the server:
KERNAL LINUX 2.6.27.5 - 117. fc10.i686
GNOME 2.24.1
MEMORY 881.4 MiB
Processor AMD LE 1620
Samba Server Version 3.2.4-0 fc10
I was told the drives should appear on their own but that's not happening I am not able to sight them at all file sharing and printer sharing is enabled.

I am having some bizarre problems with a 10.10 install which I am hoping someone here can give me a little input on. Some background info: I have a laptop which I had originally put 10.10 on about 4 weeks ago. I was using the Network Manager applet to change the MAC address by entering a valid MAC in the "Cloned MAC Address" field, and then connecting to a network. This suited me fantastically as the applet applies the MAC to any interface that connects - ie. the internal Intel card or the more often used external USB RTL8187L. For reasons which would take a lot of explaining (and now kicking ones self in the head) I had to install Windoze on the machine for a week to get some specific stuff done - but have now come back to 10.10.
The problem: So just as before, I installed 10.10, connected to my router (without changing MAC) installed system updates and other packages such as Macchanger etc and got the system working and customised how I like it. Problem is, now when I enter an address in the Cloned MAC address field and attempt to connect, the applet just sits there with the pulsing waves likes it's trying to connect but it cannot. Whilst this is happening, ifconfig -a shows that the MAC has indeed been changed. Until I remove the Cloned MAC address entry, I cannot hop on my router - or any other for that matter. Before, these steps were enough to ensure correct and functional cloning.
Things to know: This happens whether I am logged in as me or root. There is no MAC address filtering on 3 routers I have tested on (different brands). There is only MAC filtering on a 4th, and in that case, the cloned MAC is in the routers whitelist. This happens whether I specify IP details and if DHCP is used. All 3 routers without MAC control have been reset. All settings to do with wlan0/wlan1 in the network applet have been removed and re-entered. It happens on 2 different wifi cards (Intel and RTL8187L) but they worked before re-installation. I have also tried the usual commands in the terminal such as:
su
ifconfig wlan0 down
macchanger --mac (mac here) wlan0
ifconfig wlan0 up
also tried hwaddress ether 12:34:56:78:90:00 etc - The problem doesn't seem to be in changing the MAC, more the functionality of wlan0/wlan1 afterwards. I have also tried (although, it worked fine without this before) adding lines to /etc/rc.local and /etc/network/interfaces. It would be worth noting that either networking was restarted or the machine was rebooted after each alteration. No avail.
I can't think of anything significantly different that I have done to this re-installation compared to the first time, so I am not sure if perhaps in the time that it took me to reinstall 10.10, a package update has come out which has altered something and it's chucking a spanner in the works. Having said that, I even reinstalled AGAIN without applying any updates and same result. I would consider myself moderately experienced with Linux - so I am pretty sure that I am not making a complete n00b mistake... this situation is just so puzzling. I have been googling for quite some time and can find others with similar problems, but no actual solution.

I had a dual install of Windows and Ubuntu working for a good week, then I reinstalled Ubuntu, completely wiping the machine. My connection is greatly reduced--updates take hours to install, but internet surfs okay.
Code:
mieum@mieum-1000HE:~$ sudo ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:24:8c:29:5e:4b
inet addr:59.17.55.227 Bcast:59.17.55.255 Mask:255.255.255.224
inet6 addr: fe80::224:8cff:fe29:5e4b/64 Scope:Link

I am running 10.10 on a Samsung n130. Occasionally my wifi adapter locks up, everything looks like it is connected but I cannot connect to the web. I have worked out that removing and re-installing the windows driver brings it back to life (a restart also works). What I was wondering is could it be possible to create a script that would carry out the removal and installation of the driver with one click of a button.

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)
But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)
The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.
Is there a way to have both of these pieces of functionality?
I am using FC14

I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
[87.186415] Stack:
Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.

I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
Code:
#!/bin/sh
case "$1" in

I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common
aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.

I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?

my wireless home network is not recognized by my network card (RealTek RTL8190 mini PCI). The post was as follows: "I am using a new computer with Windows 7 , Athlon quad core 2.60 64 bit, 8GB RAM. Internet conection works fine with ethernet but ubuntu does not see my wireless network. card (RealTek RTL 8190 ID: 10ec:8190). Have searched this forum but unable to come up with a fix. I was looking for windows XP drivers to use Ndiswrapper but could not find a list of .inf files. My network is OK and works perfectly in windows and with my 2 laptops. Can anyone point me in the right direction? Additional info: install was done within Windows using WUBI to a separate partition on my HDD. I am new to this and thouroughly confused as to the procedure for installing the drivers if they are in fact available."
I am very frustrated in that I would like to use Ubuntu 10.04 but it is useless without internet connectability. I am new to linux and do not understand where to get the appropriate drivers or how to install them. I wish someone would answer this post and either give me a clue what to do or just say "give up" and uninstall ubunutu.
