Networking :: 3G Modem On Debian Try To Share Connection With Lan
Mar 21, 2010
Generally I don't like just asking stuff but just can't crack this one. I got a debian machine. My internet connection is on a 3g usb modem. It connects perfectly. Then I downloaded DHCP 3 and then configured it so I got 172.16.0.0 network address with gateway on 172.16.0.1 (set by DHCP) 172.16.0.1 is also the eth0 address and is assigned as fixed by DHCP. With the modem not connected the other PC connects no prob, gets the default gateway and get assigned an ip by DHCP and there is a proper connection with APACHE serving pages. So it is all grand. Where my prob comes in is that I am not able to get traffic from the modem through to the other PC, and at times the modem would not be used as default connection with eth0 up. Restarting the modem fix this but then also drop the assigned gateway address.They are connected directly via crossover cable. The modem is setup as ppp0 according to ifconfig and then ethernet as eth0 and I tried some masquerading allowing all traffic through but does not seem to do the trick.

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.

My internet is provided by a 3g modem usb. I am sharing the internet connection through my desktop into a router and then to the rest of my Ubunut machines. Currently if I want to file share I have to go into the network manager and change the eth0 settings from shared to dchp automatic and then unplug the cable from the internet port on the router to one of the network ports. Is it possible to add another network card to the main machine and use that exclusively for either internet or file sharing.

I'm running F12 on a Toshiba Satellite laptop. I don't have any problems connecting to eth0 or wlan0 when I'm at work or when connecting to a variety of cable modems, but for some reason I can't connect to AT&T/Bellsouth's dsl modem at my house (can't connect directly, much less through my DI-524 D-Link wifi).Does anyone have any idea why? I've been through every setting I can think of and I've stayed on the phone with techsupport for AT&T and physically watched as they've pinged and reset my modem, so signal into the house/modem is good....and I can hit the modem's IP and go through all of the configuration settings and everything from Bellsouth says that I'm connected and online, but when I attempt to go to another website like google or yahoo or fedora.com, I get a message telling me "Server at ******** not found."After spending 2.5 hours on the phone last night with tech support, I came into the office tonight and hooked right up to TruVista's (cable) network.

I have a usb modem which I plug into my ubuntu 10.10 system for a dial-up service. The modem is recognised by wvdial and dials properly, but the connection is not established.I get "Unable to run /usr/sbin/pppd" (although pppd is certainly in /usr/sbin), followed by "Check permissions of specify a 'PPPD Path' option in wvdial.conf", and finally "Connected, but carrier lost", then it gives up.

I have a MTS MBlaze USB dongle, with which I can connect to the internet. The question is, how do I set up a ssh connection accessible over the internet so that any one can connect to my PC through that (using valid username/password provided by me of course) ? If not possible, what do I need to make this possible ?

I'm trying to use Speedtouch USB modem.
According to [url].
After a bit of fighting interface works I can ping any domain name or ip address. I can even connect to web server via telnet, for example telnet www.org 80. I can see the response from Web server, but Mozilla says that it is offline, System Update says that no connection.
What can be the problem if manually I can connect but any Gnome GUI program says you are offline?

I'm running Lucid xubuntu. i have a netgear WG111v3 usb wireless card. The router and the modem recognize each other,. but the connection drops constantly.Other times it takes many tries to connect. There are 3 windows and one Xbox users in my house, all on the same router. When I spoke with 2 different people at Radio Shack, I was told that the software on the router is Windows based, so the Windows modems get top priority over Linux, hence the dropped signals. I was advised I could do One of three things:
1. Buy another router, one that specifically recognizes every operating system. That way, we all get equal bandwith.
2. Buy an antennae that boosts the signal.
3. Buy a booster for the signal that one cable end plugs into the router,then the device into a power outlet; the other in any power outlet, and then hardwire that to my ethernet card in my computer, so the signal stays constant. This is the output from the terminal:
[Code]....
Based on this information, what would be my best option. I can't run line all the way across the house to my computer; that would take 50-75 feet after winding it's way through the house. I don't use the ethernet card although it's still in the machine. Could it interfere with the signal?

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).
Code:
dns_domain_lo="MYNETWORK"
config_eth1=("192.168.0.1 netmask 255.255.255.0 broadcast 192.168.0.255")
config_eth0=("dhcp")
routes_eth0=(
"192.168.100.1/32 via 0.0.0.0"
) dhcpcd_eth0="-N"
This works but after a period of several hours to several days, this static route disappears from the routing table.

I am wondering how I can share connection with my IPv6 connection.
I am using slackware and ip6tables so far. But the problem is that IPv6 or ip6tables has no "-t nat", so how could I just simply share Internet with the computers behind the firewall?

I've been trying to get a USB modem stick to work with Karmic.The modem is the ZTE MF626 HSDPA on a Telstra Next G plan.I've followed all the guides and links on the forums:Have deactivated the CD autorun on the USB stick in XP lsusb is showing "Bus 002 Device 003:ID 19d2:0031 ONDA Communication S.p.A." demsg is showing "usb 2-2: GSM modem (1-port) converter now attached to ttyUSB1"This seems stable as well, ie checking periodically it doesn't seem to be disconnecting By the way,the blue light indicating network communication/modem active lights up after the device has been plugged in for a second or so.
When I go through Network Connections and add a new mobile broadband connection, there is nothing listed in the "Create a connection for this mobile broadband device" drop-down on the first configuration screen - all the guides I've read say that it should be listed here, but none say any debug steps if it doesn't.Some other guides for older versions of Ubuntu and earlier versions of the modem reference a "/usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi"file which I don't have.

I have two Desktops. Both running Fedora 9 and connected to each other with a crossover cable. I have a GPRS connection via a USB bluetooth Dongle. I can connect thru rfcomm on Kppp. Assigned static ip's 192.168.10.1/2 and can ping from one computer to the other. So far so good but now I want to share the internet connection between the two computers and run into a maze of gateways and DNS and iptables and am spinning around with no clues. Some of the things I do not understand are
1. What gateway does one assign when your computer directly connect to the internet through a GPRS and not through a NIC or router??
2. When I try to load the shared NFS folder, why does it say "could not load the location: internal error"?
3. Is there somewhere I could get a step-by step instruction??

I'm trying to connect two PCs to the Internet (or at least to create a local network) using a crossover cable. My main PC (the one that has two ethernet adapters and is connected to the Internet) runs Windows 7 and my secondary PC runs Ubuntu 10.04.Unfortunately, it doesn't work. Both systems send out packages but don't receive anything. How can I possibly fix this, so that I could use LAN and share the Internet connection between PCs? Does Windows need special software to recognize Ubuntu (or the other way around)?

I have a small wireless network running IPv6 connected though a 802.15.4 usb stick, and a network connection through eth1. I can access the nodes on the wireless network from my computer, but not from any other on the wired LAN. Also the nodes on the wireless cannot see even the address of eth1. I'm guessing i have to forward all packets from the wireless to eth1 in some way, but am unable to find an guides for this with IPv6.

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 have got a laptop running Debian squeeze. I wish to share the wireless connection of the laptop (wlan0) to the ethernet port of the laptop, so that I can share the wireless connection to my desktop PC which is connected to the ethernet port.
[My desktop PC]---Ethernet---[My laptop]---))) WiFi )))---[Public network/ ISP]
I have read the article on Ubuntu community: [url]
I followed the steps, and the /etc/network/interfaces file on my laptop is:
Now the situation is: My laptop can connect to Internet (i.e. ping debian.org from laptop is fine), my desktop PC can connect to my laptop (i.e. ping 192.168.1.1 from desktop PC is fine). However, the desktop PC cannot reach the Internet.
I also read the information on Debian Wiki: [url]
It seems I must install and configure ebtables before sharing my wireless connection to ethernet port. Is it true? (But why the article on Ubuntu community doesn't mention it?) Or I just made some mistakes?

Trying to share my internet connection with other computers on my LAN. I've tried doing this with Debian, Ubuntu & Fedora so far...
My Intended Setup is as follows;
The Problem: So far I've not been able to get an internet connection from any computer connected to the HUB. I currenty have Fedora 13 on PC1 but have also tried with both Ubuntu 10.04 & Debian Lenny. I am open to using any Linux based distro on PC1 as long it has a Gnome Desktop. eth0 on PC1 can be Static or Dhcp, but I would prefer to set Static IPs on eth1 & all of the Client PCs
To the best of my knowledge I have enabled ipv4 forwarding in sysctl.conf (& some other changes);
Code:
All changes I made to the Firewall (all other Firewall settings are still at default, no custom rules added yet);
Router is set up to assign dhcp from 192.168.xxx.100 & 192.168.xxx.200
At the moment I have only 1 PC attached to the HUB. It's Ubuntu 10.04 (PC2)
It's details are;
ip 192.168.xxx.103
netmask255.255.255.0
gateway 192.168.xxx.101
Thus Far I can't ping 192.168.XXX.103 from PC1 & I can't ping 192.168.XXX.101 from PC2. (unreachable) I have an internet connection on PC1 (of course)

From the command shell, how do I get to a network connected drive?I do a "Connect to Server" -> "Windows share" and connect to one of my Windows XP systems. Everything is fine. But how do I get to that drive from the command line prompt so I can do terminal commands or open files programmatically (hmmm is that spelled right?) Thus far, I see no way to do it.
