Ubuntu Networking :: Internet Bandwidth Does Not Share Effectively?
May 16, 2011
I have an Ubuntu box, and there are two another PCs with Windows XP at my home.There is a TP-Link WR340GD wireless broadband router, and a Motorola SB5101E cable modem. Maximum download speed of the Internet connection is about 6 Mbit/sec.While I'm starting some download processes on the Ubuntu box, the other two PCs get only small bandwidth according to their users, although download speed on my computer does not often exceed its maximum.
More precisely: I usually download files at approx. 1 Mbit. The other users complain about that I slow down the Internet connection at their computers, and tell me to stop using the Internet.Is it possible to improve the usage of internet bandwidth, and share the connection fairly between computers

Is it possible to share bandwidth over Internet? A friend of me has made a little radio station with win-amp to screw around with. But as you can guess after 10 users the connection flips due to bandwidth limits. So we where wondering if we somehow can share both our bandwidth. I was thinking about perhaps linking some proxy's and combine that with load balancing... Something like that! But i'm not even sure if it's possible to do so.

I have a router having four ethernet ports and bandwidth of this router is 500kbps. Suppose one user used one Ethernet ports only rest of Ethernet ports are free, that user should get 500Kbps. If I Add one or more user to any of the Remaining Ethernet ports how can i equally share a bandwidth among those two users ,it means each user should get 250kbps.

I have a UBUNTU server 10.04 LTS with 3 network interfaces (eth0,1,2) which eth0 is connected to my lan and others connected to two different ISPs , I would like to know is there any way to share bandwidth of this two ISP for my LAN , I mean for example if eth1 has X MB bandwidth and eth2 has Y MB bandwidth my clients those who use download manager for downloading file from internet has X+Y MB download and upload bandwidth.I do not want just limiting each user or service to use one of those interfaces I want to share them for all to increasing my internet bandwidth

My linux box has 3 network adapter. eth0 connects with ISP, eth1 is for staff network, eth2 is for public user. I want to limit the usage of internet bandwidth. for example, the traffic going through eth0, 75% is for staff network, 25% is for public user.In addition, I setup shorewall on it for port forwarding and filtering, but I felt the traffic shaping of shorewall is complex. I don't need the specific TOS, but only the percentage. could you give me some suggestion?Which software or package I should use to achieve this goal?

I created a the class like this for shaping the packets with a specified bandwidth rate.....
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 15
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 750kbit ceil 750kbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 600kbit ceil 750kbit prio 0
For Our Requirement:-
I dont want to specify the bandwidth rate strictly like this rate750kbit ceil 750kbit,based on whatever speed is coming which should allocate the bandwidth rate for particular class...I need one application for finding the upcoming bandwidth & Is any other method is there for specify the bandwidth rate in a classes.

I have a computer on my LAN that I'm using as a file server for my photography work. What I'm wanting to do is allow my business partner be able to access the file server from his home over the internet. I'd also like to create a share folder on each of our computers so that we can each access and modify so we can sync our work easily without being in the same office.What would be the easiest way to do this and how exactly do you access another person's computer over the internet?

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)?

For a very special project, many hardware issues, unusual limitations, etc, I'm turning my ubuntu into an access point (temporarily) by sharing the Internet from one device to another. I found out that with the devices I'm using, this can't be done with the network manager.
I need to get the internet from a device called 'tun0', to my 'wlan0', so it can broadcast it as a very special access point. I've read that there are ways to do this with the terminal.

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

My computer running Ubuntu 10.04 (latest) is connected to the internet via an ethernet cable. I would like other devices to connect to the internet by sharing its connection via wifi. Is there a guide to do this? I haven't been able to find one which works out of the box.

I have two wireless cards on my pc. One connected to the Internet and one free. I would like to connect the free one to a adhoc network with my netbook to share my connection because my netbook cannot reach the other side of my home.

I want to share my internet connection with my netbook which has a Win 7 starter OS. This is what I did: in Network Connections I set the IPv4 Setting of my network card to shared with other computers, plugged in the network cable into both machines, and now they both see a connection. Win 7 only sees the connection as Unidentified network with "No internet access". What should I do?

I have an internet connection called 'tether0' in ifconfig.I also have a connection eth0 which is connected to a wireless router. I'd like to share the 'tether0' connection with the wireless router, so that wireless clients will access the internet through tether0.The guides I've seen don't seem to apply to my situation.how I should proceed? I'm not very experienced with networking,but understand most of the basic and intermediate terminology.

In the documentation at [URL] it says
Quote:
Note: To clarify the above example here is an example configuration that will work - * 1. You are already connected to the internet using your wireless on port wlan0 * 2. The ethernet port eth0 is connected to the PC that needs to share your internet connection (or you could wire eth0 to a router for multiple machines)
I am trying to do precisely this, with my laptop aready connected to the internet via my HTC Hero on port usb0, and the router needing to share the connection plugged into the laptop's port eth0. Port eth0 is set to "Shared" as the doc describes.
The router in question is an old WiFlyer pocket AP, which has a fixed and unchangeable IP address on its wired port of 192.168.7.77. What happens is that when I plug it into the laptop's eth0, NetworkManager pops up the "eth0 Connected" message...and then "Disconnected"...and then "Connected"...and then "Disconnected"...etc.
I want to be able to share my cellphone's Internet connection through the laptop and out into the WiFlyer so that others can get a wireless connection in a location that has no other form of connectivity.
[Rooting the Hero and making it an AP won't work: it can't run Froyo and it can't broadcast wireless.]

I thought this will be as simple as in Windows 7 (connectify+virtual router). But it's not. So far I've managed to install a driver for an usb wifi dongle and now Ubuntu sees it
Code:
$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 unassociated Nickname:"<WIFI@REALTEK>"
[Code].....
Could it be that the wifi interface is down or something?
PS. when I left click on network manger, I see that under wireless networks it's written "disconnected".

I am running Ubuntu 10.10 on several desktops but they are not close to my router. I would like to use a wireless connection to go from my router to my Ubuntu laptop, then a wired connection from my laptop to a desktop. My laptop is WiFi enabled and has an ethernet connection.

After some fiddling around, I have come to the conclusion my current wifi access point hates my other computer's Broadcom chip or the drivers thereof. So, my current idea is as follows. I would like to use my netbook to connect to the wireless network, and then connect my other computer to it through ethernet. My netbook is dual boot XP and Ubuntu (think Ubuntu is a version behind) and I would be fine to set up this sharing in either and just leave it on as a repeater station. My other computer is dual boot XP and Fedora and I would prefer this work to allow me to have network in both. I have a straight-through cable and have verified that my network card supports the automatic crossing over behavior.

I have been trying off and on for weeks to share my Internet connection with a Windows XP client (netbook). While I can ping back and forth between the two machines, in the form of a ping test, I can't get to the Internet from the client, no matter what I try.
My Ubuntu 9.10 desktop (host) has two NICs, eth0 and eth1. eth0 connects to the Internet. eth1 goes to the Windows XP client. Regardless of whether I use an Ethernet crossover cable or a standard cable, I can get the two machines to talk to each other, but no further.
Things I already tried:
-Tried setting eth1 to "shared" mode in NetworkManager on the host. I set the Win XP machine to automatically acquire an address & DNS. Didn't work.
-Manually configured the IP settings on both machines, like this:
client:
address 10.0.0.2
subnetmask 255.255.255.0
gateway 10.0.0.1
[Code]....
Despite all of the above, I still cannot share the host's Internet connection with the client. I don't understand where the client's traffic is going, and why I can't share the connection. As far as I know, I am not doing any sort of firewalling or blocking on the host, so there is no obvious reason that the client's traffic simply disappears. I just know that whenever I open a Web browser on the client, all I ever get is error messages.
I have had no issues setting up a shared connection when the host runs Windows XP, so I am pretty sure there is no broken hardware causing the problem. Why can't I share the connection under Ubuntu?

My friend is trying to share his clearwire connection with me using Windows ICS. Using network-manager or wicd, I am unable to connect to his share. I am able to connect unencrypted with iwconfig, to the ad-hoc network, and then use dhclient to gain ip address.
I am not able to connect to WPA encrypted share using network-manager or wicd. nm-applet crashes when trying to connect. I am attempting to setup wpa_supplicant, but haven't got it working yet.As usual, the wireless networking out of the box experience in Ubuntu doesn't work. This is extremely frustrating. If Ubunut's goals are to be the default desktop, then these guys need to get wifi that "Just Works"...

I want to share my internet connexion via ad-hoc WiFi. If it's unsecured, it works fine, but when I use WPA encryption, it doesn't work anymore! I can connect from my iPod touch, but no internet. I connect to the internet from my laptop, via eth0 I want to share my internet connection via wlan0 I have no idea what's wrong

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.

Just recently got a new rig, and was wondering, is there a way to share internet via a switch. I understand the problems with switches is that they dont assign IPs like routers do, but if my ubuntu machine worked like a router by assigning IPs, could it work? Current setup is as such. I have one ubuntu machine with 1 ethernet port (this shall be the main preferably) 1 mac with a single ethernet port 1 modem with a single ethernet port that cannot assign more than one IP address. And a 5 port switch. Would it be possible to place the modem into the switch, get the ubuntu machine to receive the IP address, and broadcast all other address' to everyone else via the same switch and ethernet cable?
