lost my internet connection on fedora 12 ? i try to assaing the ip address manual in the configruation part but no nothing happen I've tried googling for the problem
View 4 RepliesI'm using Xubuntu 8.10, network-manager, Atheros AR2413 802.11bg NIC, and Radeon Xpress 200M with open-source ati drivers.
My problem is that I'm frequently losing my internet connection--whether I'm wired or wireless. It happens most often when I'm watching a ..... video but it happens other times too. My cpu usage is high when watching ..... (70-100%), so that may have something to do with it but I'm here because I really don't know.
I started having this problem when I switched from the proprietary fglrx driver to the ati driver. I switched because my laptop was always freezing halfway through a movie using vlc/mplayer. The ati fixed this but gave me my current problem. I do not want to go back to fglrx.
Here's what I've done so far to try to fix it without success:
-tried using noapci boot option
-tried using a different router
-tried using wicd
When I lose the connection I still have a strong signal. My lshw and iwconfig outputs are the same as before I lose my connection. However, I cannot ping my router when I lose the connection. I have to reboot to reconnect.
I just installed fedora 10 on a machine with a netgear ga311 gigabyte Ethernet card. Usually when I start it up I have a connection but after 5 minutes I lose the connection.
View 4 Replies View RelatedI am a windows user with no linux experience prior to Friday. Im setting up a music server (SqueezeCenter) running Fedora 10.
With the help of posts of this site Ive made good progress with complicated stuffnamely getting Samba and VNC working. My Fedora machine and my windows machines now see each others shared files, and I can control my Fedora machine from my windows machine. (The Fedora machine will ultimately be headless.)
But Im having trouble with a seemingly simple issue setting up my Fedora box with a static IP address. With DHCP enabled on my network Ethernet adapter, all works fine. I then used the System>Administration>Network menu to disable DHCP and to assign the same IP address that DHCP chose. When I do this, two cases need to be distinguished:
1. If I keep the box checked for Controlled by Network Manager, the Network Manager Applet reports a network connection, I nevertheless cannot access the internet, but my Fedora machine is able to communicate with my Squeezebox music player (connected to my network via my DSL modem Ethernet connections, and with a fixed IP address). 2. If I uncheck the box Controlled by Network Manger, then the Network Manager Applet reports no network connection and my Fedora machine is not able to communicate with my Squeezebox music player (and I of course have no internet connectivity).
Ive seen references on other posts suggesting that the Network Manager service be disabled. But I see no way to manually configure the network.
I am running Karmic AMD64 on a homebrew desktop PC, but I also previously had this trouble on 32 bit with different hardware and on Ubuntu 9.04 and 8.10. The router is now an ADSL+ Thomson TG585n supplied by O2 and badged O2 Wireless box III. The PC has a direct ethernet connection. The router was replaced by O2 when the problem first appeared, as the Wireless box II was suspect. However, I still have the problem and it is getting more frequent.
The symptoms are these: I generally shut down the PC each night, and only fire it up again when needed, which is usually the following evening, but it remains on for most of the day at the weekend. Very often when started, I find I have no connectivity to the internet, and cannot retrieve my emails. Strangely though, the Skype connection is still present and works, although not every time. My wife's laptop is connected over the wireless link - and that STILL WORKS! Sometimes I can connect to the router interface, but sometimes I can't. I've never lost the connection while the PC is running.
I have tried everything I can find in the router (when I can connect) and also in the Systemreferences:Network Connections and also in System:Administration:Network Tools, but can't find anything that helps. A re-boot of the PC doesn't help. A re-boot of the router doesn't help. A hard reset of the router on it's own doesn't help. The only solution to restore the connection is a hard reset of the router (using the recessed reset switch in the back) followed by a re-boot of the PC.
Since the Skype service remains working, and the lights on the router remain normal and wireless service doesn't fail, I think this has to be a DNS server problem. In the previous release, Jaunty, I changed the DNS service to OpenDNS within Ubuntu, overriding the router's settings. That seemed to help a great deal, although there was still the occasional outage which might have been another cause. I can't find anything in the GUI interface in Karmic that will let me do this, and I can't now remember how I did that in Jaunty.
Since I installed Ubuntu I've had this problem that makes me loose connection to the Internet. The wireless-icon on the panel starts loading, and after like 5 minutes, it works again.I had this problem when I had Mint 11, but it happened more often.Anyone know how to fix?

No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.

View 2 Replies View RelatedI have an Ubuntu Server 10.04.1 that I have given a static IP address. Every six hours or so I will lose connectivity to it and when I type ifconfig to look at the network information, it has been given an address via dhcp. If I run the /etc/init.d/networking restart command the IP address goes back to my static address and things are fine for another 6 hours or so. Here is what is in my interfaces file:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.60.82.15
netmask 255.255.0.0
broadcast 10.60.255.255
gateway 10.60.254.254
This machine is also a DHCP server and I checked to make sure there are no other DHCP servers on my network. Right now my fix is to have a Cron job running that runs the reset command every 5 hours, but I would like to find a more permanent solution.

A friend of mine is running Ubuntu. He used to run Windows XP, but he kept destroying it completely, and I soon got tired of fixing it for him. So I setup Ubuntu, and we're both happier people for it.BUT! The other day he asked me to setup a VPN (PPTP) connection to his workplace, which I promptly did. It also just works, except for one minor problem: When he fires up the VPN connection, I lose the ability to connect to his computer over SSH. As soon as he shutdown the VPN connection, I can once again log in over SSH.I use the SSH connection for basic maintenance and for tunneling port 5900 so I can assist him over VNC.
His nic is setup with DHCP. Gateway is 192.168.57.1. Port 22 is NAT'ed to 192.168.57.2, which is the IP his computer is assigned by the router (it's reserved to his MAC address).
When he connect the VPN, a new interface is created with the IP 192.168.1.32. I'm very much _not_ a network expert. I can manage the very basic stuff, but beyond that I'm quite lost.
Creating a separate /tmp partition manually during install prevents a clean shutdown.
Setup: Debian 8 minimal server configuration (SSH only) using net install as virtual machine on Windows Server 2012 R2 Hyper-V (Gen 2).
1024 MB RAM, 20 GB VHDX, and 1 Processor, EFI boot
Packages installed: openssh-server, sudo, unattended-upgrades, bsd-mailx postfix
Application: IPv6 gateway using 6in4 tunnel
Symptoms: When shutting down the operating system (poweroff or reboot), the message
A start job is running for Unattended-Upgrades ( xx seconds / no limit ).is displayed on the console and will persist for several minutes before eventually timing out and shutting down.I've tried several different configurations. Any configuration that creates /tmp automatically (whole disk with single partition, or disk with separate /home, /var, and /tmp partitions) works fine and shuts down promptly. When I partition the disk manually (512 MB EFI Boot, 17 GB /, 3 GB /var, 512 MB /tmp, and 512+ swap) the problem occurs. I've narrowed it down to just the /tmp partition by testing and comparing various configurations (including/excluding partitions, placing partitions on a separate disk, changing the partition sizes, matching against automatic configurations, etc.).
I have also compared the /etc/fstab and /etc/default/tmpfs configuration file between working and non-working systems and cannot see any meaningful difference.
I did a clean install of 10.10 just under a week ago and something is really wrong with my wired connection. I keep loosing all connectivity and have to connect again from the panel app. After that, every thing works again for about 30 to 60 seconds and the the connection goes again. No lost connection notification pop up or anything like that, but i cannot browse the web or download upgrades while the connection is gone.
Then the really weird part. Sometimes my connection works just fine. On some boots everything is fine for a long time (hours?) but then the problem comes back. My network card is an Intel 82567LF-2 and it uses the e1000e kernel module. I dual boot to Windows Server 2008 R2 and there I have full connectivity all the time.
I have a very strange problem with my Linux Router/Firewall machine where i keep losing my connection on the ethernet card.
I have installed a Debian 4 distro on a PC with 2 nics to create a router/firewall machine. On nic-1 i have connected the ADSL modem and on nic-2 a laptop for testing.
What i want is to build a DMZ with public IP addresses assigned to the servers in DMZ.
Schematic example:
Code:
We have a total of 16 Public IP's assigned to the ADSL modem from our ISP configured in routering mode. Unfortunately our new ISP does not support Bridge mode, otherwise i would not have this problem. (we had modem in bridge mode working fine with our old ISP, but they have stopped so we were forced to switch to another ISP. eth1 and eth2 both have public IP addresses from the modem set hardcoded in the /etc/network/interfaces on Linux pc and on my testlaptop in the DMZ (server-1) i have set another public IP (they all fall in the same network range) I have enabled IP forwarding on Linux router/firewall and for testing the firewall is set to allow all traffic.
When i try to ping the testlaptop in my DMZ from a remote machine outside in our datacenter i get no reply.
However when i run the following command: ip addr add xx.xx.xx.xx dev eth1 to assign the public IP i have chosen for the laptop to the inner nic (eth2) and then try to ping the testlaptop again from the remote machine it still does not reply ... but (and here is the most bizar thing)...
When i then run the following command: ip addr del xx.xx.xx.xx dev eth1 (where xx.xx.xx.xx is the ip of the testlaptop) and try to ping again from the remote machine then it seems to be working fine ... however only for a short time because then connection is lost somehow.
My wireless network is giving me a fit. Slow transfer speeds and then I lose connection and have to reboot.

Sorry if this has already been solved;answered anywhere else - I tried looking it up but to no avail. The problem persists & the hints I found around the forum did not provide a solution to the case, neither other net solutions i looked up I run Winblows at the lab and sometimes take my Ubuntu PC with me. There is an open Wireless network where they set MAC permission, and there's no pwd to access. It so should be fairly easy to change m MAC and access it, right! No. I run ifconfig and macchange, successfully change my MAC addr BUT the connection drops! Then if I change it back (MAC to my original address) it goes back online. And yes, I shut down the service -- "ifconfig wlan0 down" and then up..WHAT ON EARTH am I doing wrong??? No webpages touch this 'trouble-frigging-shooting instance!

If I check the CM logs, it appears that it has rebooted itself prior to the loss of connectivity.

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).
As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message
Quote:
Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0
If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.
If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.
Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.
Does anybody have an idea how to enforce that the vpn connection is actually used?
I'm setting up a computer with xUbuntu installed and wan't to run it as a PPtP VPN server.
I'm using a mobile broadband for internet connection, with DynDNS wich updates the host with public IP-address.
I've managed to set up the connections and installed the needed packages. The problem appears when I connect to the VPN server through another computer;
When I get connected to the VPN server the remote computer recieves an IP-address from the server (xUbuntu) wich is great! But the server changes prefered network, from the mobile broadband to the wired network wich results in the remote computer losing it's connection to the server.

View 3 Replies View RelatedI was trying to assign the static IP address of my internet connection to my home server and managed to make a mess of it. I've configured the router to assign it the address every time but when I rebooted everything the server is cut off from the network completely (rather unfortunate with a headless server...). The only file I've edited on the server when trying to do this is /etc/network/interfaces, everything else network related is default. My intention in editing the file was to make the server accept the IP address assigned by the router since the router was already configured to assign the right one. I put in

I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.
I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.
