Ubuntu Networking :: Connecting Through A Cable Modem?
Jun 23, 2010
I am using ububntu 9.10,and have a cable modem internet connection. All I have is an ethernet cable given to me,and when plugged in a windows machine and fire a browser am redirected to default login page where i can login, but when i plug it into my linux machine,i cant get the same done. In network connections it doesnt shows my autoeth0, i have deleted my existing dsl settings(not autoeth0),made a new wired network,i doubt what should i put into MAC addrs field(i have put my machines mac given by lshw -c network.) What should I put in DHCP client id? Anyways when i click on network connections it says under my wired connections-device not configured properly.
i'm having problems connecting to the internet unless i manually enter the IP info.
automatic DHCP does not work. I'm on a dual boot machine vista/ubuntu 10.04 LTS connecting to the internet through a lynksys wireless g router and a cable modem.
Linux box could act as a router? I have one machine running ubuntu, another running windows 7, a cable modem and a switch. Is it posible to share the connection between both computers by making the linux box a "router"?
I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.
I am writing a simple script which will transmit files over a serial connection. I have simplified the setup to test the solution, so the final configuration will be a bit more complicated.
Current setup: 1. 2 RS232 com ports connected with a null modem in between. 2. Open minicom on both 3. Put in 19200,8,N,1 as parameters 4. Open text travels both ways 5. Files sent over Zmodem transfer well.
Both serial adapters are USB, but I tried it also with real com ports, and same story. For simplicity, I will call one adapter "receiving" and the other "sending" to signify from which side I want to send the files through zmodem.
Then I close minicom on the "sending" site without reseting the port (I have also tried setting everything up with stty)
On sending site:
Code:
I tried googling but no solution helps. Please do not try to suggest to use minicom on both sides, because this is going to be an unattended process in the end.

Ubuntu and Xubuntu read my Motorola Surfboard SBV5120 cable modem via USB "out of the box"; Puppy LInux doesn't. The computer I've run them on doesn't support ethernet, so it has to be via USB. what can I do to get Puppy online?
I have a vista computer that is connected to a router via a ethernet cord. The router is connected to the internet.I have a computer installed with Debian that does not have a ethernet port in the back of it. Is there a way that I could connect my Debian computer to the internet through my vista?
I cannot connect my Dell Inspiron 1300 through the NetworkManager "wired" connection, when I try to go direct to the cable modem. It fails to connect.
If I connect the cable modem to my (linksys WRT54GS) wireless router, and then connect my laptop to a wired port in the router, it connects in seconds, successfully.
This has happened to me 2 other times, when I tried to connect my laptop to a client's cable modem, because my client did not have a wireless router available, in their home.
My wireless works fine. This has me perplexed. I'm using Ubuntu 10.04 LTS and NetworkManager Applet 0.8
I've tried some things to see what is going on, such as "ifconfig" "dhclient" as well as modifying the "Auto eth0" parameters and adding my laptop's MAC address, etc. Results were no fix or solution. I feel like I'm headed down the wrong road. Would someone set me straight? I have a feeling this is simpler than I think.
Do I have to actually reset my own or someone's cable modem to get this to work? I don't want to do that unless there's no other way. Is there? Let me know what commands I can or should run.
I have an old desktop computer that I installed Ubuntu 10.04 on. I also have a laptop with Windows 7 Pro which is connected wirelessly to the internet. The desktop does not have a wireless card and the modem is in another room. I have a spare ethernet cable, is it possible to connect the Ubuntu desktop to the internet by connecting it to the laptop with the cable? I'm not very good with computers.If this isn't possible, how would I go about connecting the desktop to the internet?
Running 2.6.29-gentoo-r1 on a Sun Ultrasparc 10 with a Sun Happy Meal on eth0 connected directly to my cable modem. Intermittently, with a frequency between a few hours and a few days, I lose internet connectivity. Running ifconfig eth0 indicates all is well and I have a valid IP address but I cannot even ping the cable modem's management address; pings to 127.0.0.1 and eth0's IP address do get a reply but no other address I've tried does. I can 'fix' the problem by issuing
Code:
If I check the CM logs, it appears that it has rebooted itself prior to the loss of connectivity. The strange thing is that the incoming traffic doesn't seem to be affected by this, my PSAD log is full of incoming scans even during the periods when I can't connect to the net. I suspect this is an ISP problem (they own the CM);
Running Gentoo with kernel 2.6.29 on a Sparc Ultra 10. I'm having problems with my cable modem connection failing, so I've added a static route that enables me to log into the modem's diagnostics page at 192.168.100.1 when the connection drops; my /etc/conf.d/net looks like this (with the comment lines removed).
My broadband internet connection came with a Nokia-Seimens C2110 Adsl modem. Please help me connect the modem through USB cable as the ethernet card is used to connect my computer(Asus- P5RD2 VM motherboard) to a different computer on LAN. I am in a fix and have no clue how to proceed.
In my attempt to get my USB 3G modem to work on Ubuntu 10.04 netbook edition I have made some progress to the point of getting the driver for it up and running, though connecting to the Internet after defining a profile is an issue. I have followed this ubuntuforums thread simply to get started with the usb modeswitch to get the usb modem identified by the system.
I've recently installed Natty and the only problem I have with it so far is attempting to connect my Huawei E5830 Three Wireless modem via USB and successfully connecting to the Internet from it. I've fiddled around with the network settings and nothing, I've also done some work in the Terminal to try and correct the problem.
running Ubuntu 9.10 x64bit fresh install and updated.When I connect with my 3g um150 modem it disconnects my home network?? I cannot get them to run both at the same time and of cousre the next thing would be to share the internet connection.

The problem is that when I connect my phone to my machine FC11 x64 via USB and use the phone as a modem NetworkManager does not recognise the phone as a modem. The phone works well on my laptop which is FC11 32bit system, NetworkManager detects it and sets it up as eth2 and away I go, no problems at all. I would like to ask the community how can I go fault finding to find out why it does not work. #lsusb shows that the modem is being detected by the system but beyond this I don't know where to look and get things going.
I was recently asked to get a 3G ZTE 633 modem (not in stores) to connect to the internet whenever it was plugged in. I had it successfully working on my Ubuntu Gutsy Gibbon machine but it does not work on Fedora 10 which is where it is required to work. When the 3G modem is plugged in I use a Udev rule to run usb_modeswitch which changes it from being in usb storage mode to being in modem mode. This part works fine. I then run a second udev rule (on the modem device), this should run a script which connects to the internet. Unfortunately it falls over here. The script does run but it will not connect. However if I run the script manually from root it works fine. I guess that it is a permissions issue.
One thing to note is that there are three udev devices associated with the modem. They are ttyUSB0, ttyUSB1 and ttyUSB2. I use ttyUSB2 to talk to the modem when connecting. Here are the files. If you require any more let me know:
The first udev rule: SUBSYSTEM=="usb", SYSFS{idProduct}=="2000", SYSFS{idVendor}=="19d2", RUN+="/usr/bin/usb_modeswitch"
The second udev rule: SUBSYSTEM=="usb", SYSFS{idProduct}=="0031", SYSFS{idVendor}=="19d2", MODE="0666", RUN+="/outputs/run_internet"
trying to connect to the internet using wvdial but facing problems. the command runs fine until i get PID ppd Carrier detected. Starting PPP immediately.
--> Starting pppd at Sat Oct 23 10:40:09 2010 --> Pid of pppd: 2520
nothing happens after this.. I checked the resolve.conf and it is empty. i put openDNS server addresses but still did not work.
I have just installed ubuntu 7.10 on my computer. The problem is getting it connected to the internet using my Sony Ericsson w580i as a modem. I have used my phone to connect to the internet on XP operating system easily. Please assist me and try to give me a more simplified step by step procedure.
I want to configure my ADSL but I don't know what should I do. Can you explain me How can I configure it?(I use fc10, ethernet cable <Asus Am608 ADSL modem)
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface auto lo iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
sometimes our ADSL connection gives up and we are left without internet connection for days until the problem gets fixed. I mean by this problem along the phone line. It affects all machines that connect to the internet through a Netgear WIFI Modem Router. I recently tried an alternative when this happens is to use a USB Huawei Mobile Broadband UMTS connection which works when you insert it in 1 laptop. Is there a way i could get the Netgear WIFI modem router to connect on that usb stick or PC that is online on that usb stick and give access to other machines that will want to connect to the web ?
I am having a problem when I hook my computer up to my tv the desktop is bigger than the screen will allow. Is there a way to shrink the desktop down so that it fits within the screen? I can not find a way to do it on the tv itself... I should also add that the resolution is set to 19201080 and the video card has a vga and dvi port. I am connecting to the tv with a dvi-hdmi cable
