Networking :: Network Has An Intermittent Fault - File Share Network Stops Working
May 7, 2011
Sometimes my file share network stops working,and will then work again.I'm lost with this problem. The server pc is a Zenwalk pc.The other pc is a win7 pc. This error only occurs on Zenwalk. When i run puppy from the live cd the file shares are always visible,without fail.Under puppy i use pNethood. When the ping command is used there is no problem, and the pc name can be pinged.This is shown below:
I'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.

and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.
I have an issue on a few servers where IPv6 stops working after a reboot. I can ping anything within the same subnet but anything outside of that it gives me host unreachable. I believe that it is not routing for some reason, but I am not sure why. I have tried adding a default Ipv6 route for Eth3 but nothing seems to work.

I just recently erased my hard drive and installed ubuntu 9.10 all over again. I updated as expected and everything was going well, until, my internet stopped working after maybe 40 mins or so after a successful boot. Now this same thing happens every 40 mins and I have to reboot the computer by forcing my laptop to shut down by holding down the power button. This also made me aware of another problem when restarting or logging off my laptop. The laptop hangs at that terminal-syled screen and the underscore blinks and fails to shut the computer down/log off. I resort to holding down the power button to restart. I am using a wireless connection with WEP key protection.
Atheros network chip Laptop Acer Aspire 5532 It just happened again..... I am typing now in tomboy notes.... Time to restart again...... I also try to open terminal and it fails to function (after the internet stop working), any reason for that? I would also like to note that the signal strength decreases as time passes by.......
this is with both network manager and WICD, a problem i've had since i got ubuntu - multiple wipes and reinstalls the wifi is supported out of the box, the problem i've randomly run into since installing is, it will randomly stop detecting networks "no networks detected"
i've noticed over time as this as been happening, that it usually happens whenever there is a high load - multiple videos going on multiple tabs, videos queued up etc. its never happened during regular browsing - theres always a lot going on when it happens, almost like it collapses. the only way to fix this, is to quit the manager - shut off the computer (restarting doesnt work) and then it comes back after
my server which shares my internet connection with the rest of the house recently started to randomly quit the eth0 connection and the sharing connected with that. after a reboot all is fine again /var/log/messages shows the following
Code: Aug 18 19:53:36 Gomorrah kernel: [93072.000029] ------------[ cut here ]------------ Aug 18 19:53:36 Gomorrah kernel: [93072.000048] WARNING: at /build/buildd/linux-2.6.31
I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
My samba seems to be mis-configured somehow. I had been using Ubuntu 10.04 and my samba browsing of my samba shares on my HTPC (running XBMCLive) had all been working fine. Then I upgraded to openSuSE 11.2 64bit. Great OS by the way!Ok so I chekced my other PC's running Ubuntu and going to the network folder I see my XBMCLive machine. Double click him and now I see my shares on that PC. So now I know its specific to my SuSE install.
Now on SuSE if I use Dolphin file manager and go to Network -> Samba Shares -> workgroup I dont see anything. And then down the bottom of the window I will see timeout error on workgroup. "workgroup" is the correct workgroup. All the services are running winbind, smbd, nmbd, xinit, swat. Firewall disabled.However when I try the above and I get the timeout error I then go to the address bar in Dolphin where it has smb as the drop down item and in the text field type in the XBMCLive PC ip address and hit enter. Then immediately I can see my shares!!! So it is working but I cant see my shares under Network->Samba Shares->workgroup.I notice in my samba error logs for log.smbd I keep seeing this;smbd_open_once_socket: open_socket_in: Address already in use
firefox is not working . error : /opt/firefox/firefox-bin error while loading share libraries: /opt/firefox/libxul.so. cannot restore segment prot after reloc: permision denied.when i start firefox above error rises on linux terminal.
Over the past two months I've migrated two NetWare servers 6.5 SP7 to SLES10 SP3 and OES2 SP2.'ve had some consulting assistance and been learning linux as I go. Now I have a b!tch of a problem with a Dell PE SC 1430 with integrated Broadcom BCM 5751 GB Ethernet working ok, but then after a reboot it will come up with no networking. I've used Network Manager to configure a static IP but it willsometimes come up and ifconfig will show no ip assigned.I can manually assigned ip, netmask, gw and can ping the gw, but can't ping any host on the subnet. I disabled the integrated NIC and installed another, but same problem.
My problem is that my wireless network traffic sometimes just stop.Like when I tries to update my system, update NetBeans or just download using Uget. I have no clue on what's wrong,Here is my system info:
I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?
i have ubuntu 10.04 i believe and i cant connect to the intenret i guess its not detecting my wireless adapter. i cant try ethernet cord which prolly would work because i cant move pc to another room....is there any fix for this? i googled linux drivers but i cant find any...i do have the cd that came with the adapter.
I'm running Federa12 on my Asus EeePC 1005HA and I can't upgrade my system because my network connection flakes in and out. I'm connecting to the D-Link DIR-655 802.11n router. Any hints or ideas? I'd rather solve this than just plug-in the ethernet cable.
i have 3 comps(running suse 11.3) and a laptop(running vista sp2). i have installed samba on all suse comps. i have a printer attached to one of the comps and it has been shared also the internet connection on that comp has been shared. all the computers are connected using lan cables through an ethernet switch. i also have a wireless router which is connected to the ethernet switch.
I am able to view all the comps on the network except the laptop running vista. all the desktops are visible on the network and are able to print and share files on the network and also connect to the internet. the laptop running vista can connect to the internet but its not visible on the network and nor can it share files across the network or access the printer.
I'm having intermittent network failure on my laptop but I can't figure out why. I have a cable modem and a 10Mb/s (bits) connection (at least that's what I'm paying for). The modem is connected to a wireless router, to which my laptop connects wirelessly. Quite often my speed drops considerably-- sometimes as low as a few hundred bytes per second. Other times it fails completely. This will happen with just about any server you can imagine, including the Debian FTP mirrors in the US.
- When I do file transfers over the local network from my laptop to my desktop, they go pretty fast, around 2 MB/s. I believe my wireless card (Intel 3495) maxes out at 3 MB/s (bytes), so that seems reasonable. - When I download a file from the outside network, it usually goes pretty fast too, around 1 MB/s, which is close to my limit.
So why is it that the connection between the laptop and the external network is so slow? I've tried power cycling, but it doesn't really help. I can't think of anything else to try.
In Googling around it appears that the Network Manager used to have a nice simple (obvious, logical, straightforward, intuitive, easy-to-use... ... can you tell I'm a bit surprised that there's not a simple button to do this, it's pretty common functionality ) option in the IPv4 tab called "Shared to other computers" allowing you to share your network connection with any computers connected to yours... kind of like this:
Professor Google seems to indicate that this may have existed in Debian at one point but, I don't see this option anymore. How do I get it back (or is there another gui way to do this without editing the /etc/network/interfaces file... if there's no other way to do this... that's fine but I'd prefer an easy method of enabling and disabling sharing)?
What I'm trying to do... I have a Beaglebone Black connected via IP over USB. When I'm ssh'ed into the BeagleBone, I want to be able to use aptitude install to grab new packages etc... and that kind of requires access to the outside world. Everything I've found so far seems to to require a modification to the interfaces file but since (according to the interfaces man page) the preferred method is to use the network manager if possible... I'm trying to avoid that.
* It should be noted that I'm running sid with the experimental 4.3 kernel so... maybe in doing so I've shot myself in the foot?
I have a Karmic server install on which I've set up a network drive mapping to a NAS (CIFS). I'm having trouble with automounting the disk though, as (from what I can tell) the disk is attempting to mount before the network is up.dmesg shows the following:
Installed openSUSE 11.3 over an existing 'very stable' 11.2 installation and started experiencing wireless connectivity issues immediately. Network Manager would show connected 100% - 92% but I would lose connectivity to mail, browser and messenger(s). This disconnect would last less than 30 secs but would occur every 2 to 4 minutes.
[ 3663.672098] iwl3945 0000:03:00.0: Failed to get channel info for channel 3  [ 3664.101085] iwl3945 0000:03:00.0: Failed to get channel info for channel 3  [ 3664.529050] iwl3945 0000:03:00.0: Failed to get channel info for channel 3 
BTW Channel 3 is the channel my wifi is broadcasting on. I've tried other channels and other computers and it is only openSUSE 11.3 having an issue. I am also using WPA2. Modifying the Global Options in Network Settings from User Controlled with NetworkManager to Traditional Method with ifup seemed to stabilize most of the issues, but I do notice occasional drops. I've also switched from Network Manager to wicd to provide some UI while dealing with this issue. Since iwl3945 drivers are now in the kernel I don't know if I should try to revert to an older driver or if there is another issue.
share a Dreambox HDD over the network. To those who don't know - Dreambox is a digital TV tuner with Linux OS and in my case it has a fairly large hard drive, which I would like to make available over the Local Network, so I can use it as a network hard drive on my Ubuntu Karmic and Windows 7.
The Dreambox has an ftp server set up but I can't watch video files directly from an ftp server somehow, it forces me to download those files first. So what I want is to make that hard drive available as a normal local network shared item with permissions to read write and execute, so that I could also keep my Movies in that hard drive or maybe even be able to download to that hard drive directly.
I think it has to be possible somehow Or at least if it was possible to mount it somehow on the Ubuntu, hmm.
Be the way my Dreambox model is DM 7020 and if I connect to it using telnet it uses the sh Shell I think.
Paths displayed in Nautilus appear to be just that. Nautilus private syntax. Esp with respect to anything "special". Apparently when you hand a path like this to a program to open, you get a folder in your home directory: smb://cyberstorm/c_drive/
At least that is what my program does with it. A folder called smb: in my home directory. Probably because the default folder for the program is the home directory [~]. Is there a universal network folder syntax for the network and other "special" file systems?
I see things like: network:/// and computer:/// showing up in "properties" dialogs for some things. But these are useless to a program apparently.
At least a program written in Qt. Is this a Qt problem, or a problem with Ubuntu not yet making the network a first class citizen in the world of paths? Who do I complain to? Time for the network to be a first class citizen, right?
I have installed Samba on my one of my computers that has Fedora 12 installed 192.168.1.2, and the other PC that has Windows Vista installed 192.168.1.3 Hostname Adam-PC Network: WORKGROUP. Both PCs are connected to Wireless Netgear Router with DHCP enabled on the router as well as the two computers. How do I set up File sharing on these two systems?
I am trying to share a hard drive on the network. (Essentially the hard drive is for another computer which didn't have the physical space for it so this computer is like a holding place for the hd). I read somewhere that I can use samba to do this. But in all honesty I have no idea what I am doing. What would be the best way to share this drive? Also understand, I know little about networking.
In this post I will give a quick solution for a possible problem with sharing a folder in Fedora 15.I had to spend some time for research and frustration so, hopefully this post will save you from both. If you have Samba installed and configured to share certain folders on your Fedora machine for a Windows network but, they can't be accessed then following might solve the problem:
1. Go to Applications, Other and run FIREWALL
a). go to TRUSTED SERVICES and check SAMBA and SAMBA CLIENT that are located in the list of services b). click APPLY c). go to ICMP FILTER and check ECHO REPLY (PONG) and ECHO REQUEST (PING) c). click APPLY
If your Samba is configured correctly, your shared folder should be available on your Windows network.A little hint: if you don't want other users to use passwords for accessing your shared folder, select SHARE as an Authentication Mode in Samba GUI Configuration Tool, Preferences, Server Settings, Security
