OpenSUSE :: 11.2 - How To Reconnect Network Cable From Console
Jan 18, 2010
My network connection breaks almost every day. I don't know whose this problem - is it my system or my provider. Everything goes ok until some moment when network disappears and ping my gateway returns "Unreachable host". In that situation I usually plug out cable and plug it in again - now network works.
I wounder if there is a way to do something from console which has the same effect as plugging out/in cable? Or may be more preferred way - can I know what exactly doesn't work when network disappears? What i must repair? May be it save me from reconnecting cable

Just having updated from SuSE 10.3 to 11.1 I'm struggling with some network issues. WLAN connection setup with Network manager worked, the connection comes up on login to KDE 3 and works for some time. All of a sudden, the wlan connection fails and reconnection via NM is not possible. The normal wired ethernet stays fully operational and connection is established at plug in of the cable. I tried to track the issue down by browsing through /var/log/NetworkManager but I did not find the answer. A rcnetwork restart brings back a fully operational network including wlan connectionvia NM.
Working connection fails, NM fails to reconnect:
Code:
Jan 6 13:04:30 mars NetworkManager: <info> (eth1): supplicant connection state: scanning -> associating
Jan 6 13:04:30 mars NetworkManager: <info> (eth1): supplicant connection state: associating -> associated
Jan 6 13:04:31 mars NetworkManager: <info> (eth1): supplicant connection state: associated -> 4-way handshake
Jan 6 13:04:31 mars NetworkManager: <info> (eth1): supplicant connection state: 4-way handshake -> group handshake .....

I have a ppoe internet connection. I was easier and faster to configure it in Yast than in Windows XP. When
The provider here sometimes goes through some problems and the connection may disappear and return at any unexpected moment. In Windows there is a icon on system tray that dysplays such information and I know when the connection is gone. It also allows me to try to reconnect manually. Where do I find these information on Opensuse here do I manage to reconnect. In Windows it was also possible to set the connection to re-dial automatically when it was out. It was very useful if it failed in the middle of a download, the system reconnected and the download manager retried until download resumed. Is there some way to adjust opensuse to reconnect automatically when connection fails or some software that does it? Furthermore, is there a good download manager that works in Opensuse that pause, accelerates downloads and retries when connection fails?

I got a new cable modem so I could get rid of the one I've been leasing from the cable company. It is a Motorola sb6120. Everything is fine with the ISP, it's approved for operation on their network, the only hitch was I had to use my Windows laptop to run their activation software.
At any rate, with the new modem installed, I hop on my Linux box and go to work. I'm seeing some terrible delays in looking up names. When I look with firebug, all the dns lookups for new names are taking 15+ seconds. First I just think maybe the names aren't cached or something is weird for a minute and it will get better, but no. After several restarts and then a couple days persevering with the new cable modem, all DNS queries are still terribly slow (including zypper, mail client, web client).
Suddenly I remember an issue I was having with, I believe version 11.1 when I first installed it. For just the computer on my network with a fixed IP address, DNS resolution was slow like this and if I disabled IPv6 then all was well. I believe there was even a patch issued back then for gethostbyname() that was supposed to fix the issue? So, when I disable IPv6, DNS lookup is back to normal. The two Linux computers on my network had been working fine with IPv6 and the old modem, though, and the Windows box is still working fine even with the new modem.
I can disable IPv6 and make it fast again, but really why should I have to?

My WiFi can connect to internet without any problem, until I plug my ethernet cable ...then I lose internet.
So the question is : how do I configure my ip/dns and stuff to still have internet when I'm plugged by cable at the same time! it was working on windows ;-)

I am using Nokia x2-00 phone. I am able to connect to the EDGE/GPRS using Blueman. However, if I use the USB cable along with KNetworkManager with the same dialing number and APN I am unable to connect. What might be the cause?

Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.

I'm running squeeze testing. I have noticed an issue with the way NetworkManager acts when the wireless connection is dropped. I believe it should automatically reconnect but it immediately puts up a dialog requesting me to enter the wifi password. This dialog stays indefinitely until I intervene and click "OK" (the password from the previous successful connection is still there). I would think that something as basic as wireless networking should not require 24 hour human interaction to stay connected. I have considered a cron job checking the network status and restarting it if necessary, but there is a configuration change or something else I can do to resolve this.

I am using tcp for data transmission between 2pcs running linux.During transmission, I have noticed that if I unplug the network cable and reinsert it quickly,connection is not lost(same as i expect)and the sender start to resend the packet after 5s(what i expect is that network packets sent immediately after quick physical disconnect and reconnect).My question is can i reduce 5s to 0s(resend immediately after network cable reconnect)?Any parameters(tcp rto,txqueuelength,..) can be modified to achieve this condition?

I have SUSE 11.0 set up to act as a router/firewall for my home network to the internet through a cable modem attached to an Ethernet card. When I was laid off several years back, I found information that let me connect my network to an ISP via a standard serial modem. I am considering going to the Sprint U1901 4G USB modem and dropping cable internet. Sprint claims the U1901 is Linux compatible. My thoughts are that using the 4G modem should be similar to the old dialup modem. I had a script that connected to the internet whenever internet traffic was detected. Unfortunately, I did not save notes on what I had done to setup the modem to dial automatically, and I have been unable to locate information that seems good to set this up again. I already know that all I had to do to get routing working was simply replace the internet port in the firewall/routing script with the port for the modem. So I assume that is rather trivial.
Would you please point me to a doc, perhaps SuSE specific, that gives reasonable directions on how to set up a "dial on demand" ISP connection? I assume that the 4G modem will be very similar to my old serial modem so that a dial on demand script will work. I did find a dial on demand howto, however, it did not seem to apply.

I upgraded my openSUSE to 11.4 and wifi was still working out of the box.
However now when I turn the wifi off using the hardware button and than back on, or when I wake up from hibernate, (k)networkmanager won't recognize the wifi device... I actually have to run /etc/init.d/network restart to reconnect to network. The problem is that it worked in 11.3... why not in 11.4? Now every time I hibernate my laptop I had to manually restart network. In 11.3 it was automatic...

I have my openSUSE 11.2 connected to router by wifi. I want frequently to access it from my LAN or even Internet, but even so frequent the connection is lost for some reason.
When I am at the box, I can easily do a ifdown/ifup and it will reconnect, but that is a pain when I am not local.
is there some way or maybe a script to check the connection so now and then and if not online then re-connects it automatic ?

i cant get Qinternet to auto reconnect when connection is lost due to dynamic IP changes from my ISP.Im using Ifup method.Thing is, every 24 hours, ISP changes my IP and thus, disconnects me from the internet. I need it to reconnect but dont know how to do it.

I have a hp dv3 2110eg laptop with OpenSuse 11.1 (KDE 3.5.10) and Windows 7 dual boot. My wireless disconnects and connects automatically at random intervals. I do not observe this behaviour when operating my laptop under Windows 7. Following some suggestions given in this forum , I uninstalled networkmanager and installed wicd. However, this does not seem to solve the problem. Given below are the relevant information.

how I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:
Three Ethernet Cables
Two Printer Peripheral USB Cables
The Two Computers
A 2GB Flash Drive
That is all I can think of right now. I do not want to use CDs. In a way, I would like to do a network boot. So, how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? I want to put Xubuntu on it, and earse the rest of the Hard Drive. The computers getting this are the iMac G3s and the eMac G4. The eMac has 256MB RAM, 40GB HDD, and a 700MHz processor. Two iMacs have 128MB RAM, 40GB HDD, and a 600MHz Processor. The other iMac is the same as the rest but has a 500MHz processor.

I have a Verizon wireless/wired router that I access the internet through. I have a desktop computer running Slackware 13.1 i386, but it is in a place where it would be impossible to run a network cable to. Would you buy a USB wireless card? Would it work with Linux? Is there another way I can get my computer networked that I am not thinking of?

At the outset I would like to tell everyone that I am still relatively a newbie in linux. I use a usb mobile broadband data card to connect to the internet, and I recently purchased another desktop for my wife. Both of us do not share any files, but I do not have a router and was wondering if I could share my connection with her using a crossover cable.I did a lot of Googling around and tried various different things, I even followed another thread in the same forum but the most that I have got is my network manager saying that connection has been established. I am however not able to see her computer under my windows network and don't know how to proceed.I don't know where I am going wrong, and considering that my knowledge of networking is at below basement level, I would really appreciate any help in this regard.

I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.

I have a kubuntu 10.04 box and it runs virtualbox with windows 2000. For the most part, the network cable will be plugged in and i should be able to rdp into my windows 2000 install just fine, however, for testing purposes and for backup server testing, I will not have the cable plugged in all of the time.How would I rdp into that windows 2k install on the same machine if no cable is plugged into the ethernet port?I have both the kubuntu install and the windows 2k install setup with static ip's, but it is not working.
