Ubuntu :: Internet Connection Breaks When Idle?

Aug 9, 2010

I ve been a loyal fan of RedHat Linux for last 5 years.I switched to Ubuntu just few days back.Let me tell you, I ve already started loving it.However I m facing few issues while downloading from the Net.While downloading some softwares from the net using 'Package Manager' or 'BitTorrent Client' or directly through Firefox, I m getting the following error if my computer remains Idle for around 20-30 minutes.Error Says, Check your internet Connectivity'.I then need to Redial to connect to Internet.I never faced this issue in RedHat or Windows.I use to put my machine to download for the entire night and never faced connectivity problem.Where as if the computer is not idle and I m hitting keyboard keys, the download happens smoothly.It seems like some thread is checking my status. and if my status is Idle its disconnecting the net

Ubuntu Networking :: Internet Connection Dying If It's Idle

Jan 23, 2011

I'm using BSNL 3G USB datacard in India. After connecting to internet, if I leave without browsing, the connection is dying. But if I'm running any downloads in the background, it's staying alive. I'm facing more of this problem when I'm using Ubuntu. And if I'm browsing the download speed received is less than the speed received while downloading using a download manager.

Fedora :: FC12 - DHClient Breaks My Internet Connection

Mar 17, 2010

Latest FC12 update included dhclient-4.1.1-9.fc12 which fails to configure eth0 after restarting the computer. Had to remove/downgrade to 4.1.0* (and reinstall dracut and NetworkManager(-glib)). There is no config file in /etc/dhcp/dhclient.d so I don't know how to reset dhcp/eth0 to connect. Thought some one smarter than me might have noticed this by now and worked out a solution. Can't tell that anything in Bugzilla sounds like my problem. Might only be x86_64 or KDE-4.4 problem as my 32-bit Gnome install is not affected. Easy enough to grab the rpms, just annoying. Still haven't learned how to keep a package at version x.x with Fedora yet but that's another topic.

Ubuntu Networking :: Server With Both NICs Enabled Breaks Internet Connection?

Nov 25, 2010

I have installed Ubuntu 64 10.04 server. I have two nics and have set them up to both be static with their own IP with the correct gateway, network, broadcast, subnet and dns-nameserver. When I have both enabled, I can ping local pc's but I can't ping Internet sites like Google nor can I get out to the Internet with apt-get or Lynx.

If I disable one, then I am able to get out to the Internet. All my configs look good, and it does not matter which one I disable, just so long as there is only one NIC on, everything is good.

Ubuntu Networking :: Wired Network Breaks When Idle

Feb 27, 2010

I'm having a problem where the wired network wired network (eth0) disconnects when the connection is idle for a while (usually tens of minutes). It works fine every time I boot up, but eventually it dies, and I can't ping the machine, or ping anything from the machine. ifconfig shows that it still has an IP address. Running ifdown/ifup causes it to work again. I intend for this machine to be a server, so I can't afford to go restart it when I need network access. sudo lshw -class network gives me this:

Ubuntu :: SSHFS Over VPN Breaks When Connection Lost?

Dec 2, 2010

I am mounting a remote directory using sshfs, over VPN. If the VPN connection is lost, the directory obviously can't be read. But, when I try to "ls" in its parent directory, the command just stalls. No error messages, and ctrl-d, ctrl-c, ctrl-z don't do anything. The command I ran to mount the directory was:
Code:
sshfs -o workaround=rename bt@example.com:/dir1 /dir1

Ubuntu Servers :: FTP Breaks With Outbound Connection

Jul 24, 2011

I'm sending files to a remote server by way of FTP via a PHP script. With the firewall turned on these files are getting to the remote server with 0kb and the remote server is timing out before all the files are received. When the firewall is turned off the all files are received in tact. There are no outbound rules set in the iptables, looking for ideas on what to check next.

Ubuntu Networking :: Connman Installation Breaks Ethernet Connection

May 16, 2011

I was browsing the available packages to install the weather indicator and noticed that a network indicator was available. apt-get said that it needed to install 'connman' and remove 'network-manager' and 'network-manager-gnome' in order to install the network indicator. I foolishly assumed it knew what it was doing so I went ahead and performed the installation/removal and restarted the computer.

Now I cannot connect to the internet. I only have an ethernet card for connection to the internet, no wireless or otherwise. The configuration I use is not DHCP, but a manual settings of address/subnet/gateway and name servers

When I try to set the network values through the network indicator some of them do not stay set. The gateway value appears to be set, but then after closing down the indicator window completely it comes up with the value 'Modified'. The DNS servers is the only other value that does not stay set, but it only changes to be blank. The connection never works.

So, I downloaded 'network-manager' and 'network-manager-gnome' on another computer, transferred the packages by USB, and reinstalled them (uninstalling connman and the network indicator). But the network connection remains broken. At least with 'network-manager-gnome' the values I set stay set, they just don't work anymore. I've tried editing /etc/network/interfaces to previously working values directly, but they do not seem to have any effect either. The connection no longer works.

I really do not care if I use the network indicator or not at this point, I simply want the network connection to work properly.

Edit: I realize I forgot to say that I'm using Ubuntu 11.04 (upgraded from 10.10). The network card is the "Integrated Broadcom 57780 Gigabit Ethernet controller".

Networking :: Breaks In Fedora - No Internet

Oct 21, 2010

Another weird one I think. I have two integrated LAN's on the MB. All was OK in Windows and figured I'd do some work in Fedora 13. When I got there I had no internet. I messed around trying to get it working and gave up; went into Ubuntu; same deal. I booted Windows and the same; no network. I tried the other integrated connection and it worked. No way could I get the other nic to work so I tried shutting right down; pulled the plug; waited a few seconds; plugged it back and booted up and it's working again. Now I'm leery about going into Fedora. Anyone else have this problem. I think it happened to me once bofore and I thought my nic had bit the dust and plugged into the other connection?

OpenSUSE Wireless :: Strange WiFi Behavior Breaks Connection Repeatedly

May 30, 2011

I have recently upgraded to 11.4 and also had to renew an AP (HP ProCurve 10ag). This was several years old but replaced an identical model which had been working well until recently. I thought it would be appropriate to flash newer firmware as the device four releases behind the times. The access point serves partner's XP laptop and my openSUSE 11.4 laptop and after flashing the firmware both machines would make a connection and then break and remake, to the extent that the openSUSE machine became unusable. I thought it was an encryption problem and spent hours changing the AP and Client setups to no avail

After reading a thread here I checked out dmesg and this is what I found:-
[78.639247] wlan0: authenticate with 00:1d:b3:4b:ae:14 (try 1)
[78.640804] wlan0: authenticated
[78.642507] wlan0: associate with 00:1d:b3:4b:ae:14 (try 1)
[78.651195] wlan0: RX AssocResp from 00:1d:b3:4b:ae:14 (capab=0x411 status=0 aid=1)
[78.651200] wlan0: associated

[78.652283] cfg80211: Calling CRDA for country: DE
[78.674378] cfg80211: Regulatory domain changed to country: DE .....
This went on and on.

General :: CPUs Keep Toggling Between 100%idle And 0% Idle

Mar 22, 2011

When I run top d 0.5 on my machine and I press 1 to enable the SMP View, I notice that all of the CPUs keep toggling between 100%idle and 0% idle.

The odd part is that when a CPU goes to 0.0% idle, I would expect to see one or more of the other columns peek, but they are not.

What is causing this?

Networking :: Use The Laptop With The Wireless Connection To Share The Internet Connection?

Feb 4, 2010

I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.

OpenSUSE Network :: Masquerad Internet Using Knetwork Manager - Share The Internet Connection To A Desktop

Jul 5, 2011

OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.

It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.

Ubuntu Networking :: Internet Connection: 'Work Offline' - "No Network Connection"

Oct 31, 2010

I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.

The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:

eth0
Link encap:Ethernet HWaddr 001:aa0:91:a7:51
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets: 0 errors: 0 dropped: 0 overruns: 0 carrier: 0
collisons: 0 txqueulen: 1000
RX bytes: 0 (0.0 B) TX bytes: 0 (0.0 B)
[Code]...

If I comment out "auto eth0" as well, it makes no difference. If I uncomment both lines ("auto eth0" and "iface eth0 inet dhcp") then I lose the internet connection altogether.
