Aug 3, 2011
very slow internet connection with a download speed of only five kbps and my problem is i have many softwares installed which startup during my boot and i can see network activity in the system monitor that some software is using my internet speed and all other important downloads run slow...Can anybody tell me some softwares which tell me which software is using my internet bandwidth, I tried iftop and it shows only the connection between client and server with ip address ...I need softwares which tell the software using the internet bandwidth

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

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 just installed ubuntu 10.10 on my windows 7 os as part of a dual boot, and im having trouble connecting to the internet. I have a wireless edimax PCIe adapter and seem to be able to detect the signal fine but when i try to connect ubuntu starts thinking about it and then after a while says "disconnected from wireless internet".
I'm pretty much a noob to lunix but have a small amount of experience with the terminal, also not so great on the networking terms, so please dont go too deep to quick on the terminology!

We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.

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'm looking for a simple way to monitor and log my internet bandwidth usage. Not total network device usage, just internet usage.Something that provides a simple chart of daily, monthly, and yearly usage, but ignoring all bandwidth on my internal LAN.I notice several possible tools, such as vnstat, ntop, iftop. Yet all of them seem focused on tracking the entire network interface. I want to ignore LAN usage. I do not really care about LAN bandwidth.iftop seems intended only for on-the-fly usage and not cumulative logging. I can't tell whether vnstat or ntop can be configured to log only internet usage rather than all traffic through the network device.
I do not want to log every connection like squid. The utility should only log stats on a daily basis, but also be able to display cumulative totals from those daily entries.I don't need DNS resolution, port monitoring, etc.I prefer something that runs in the background as a service or daemon, but can provide statistics quickly with a terminal window. All I want is to view total daily, monthly, and yearly internet usage. Perhaps even pipe the output to a local email each day too.

In one of our network we are using one firewall which works as gateway. All machines are able to access internet through this gateway. There is no filtering and any internet restriction. I would like to setup monitoring system which monitor and log bandwidth and sites access by client machine. Is there any tool which monitor internet access as well as sites which are access from client machines.

I have configured a normal squid & now I want to manage internet bandwidth thru. "squid" proxy only.
Squid proxy server ip is :- 192.168.17.30
Client PC ip addres is 192.168.17.25
Total bandwidth avaialable :- 2 Mbps
Now, I want to limit bandwith of 400 kbps for the ip address 192.168.17.25 pc only. So, is there any method available for bandwidth limiting for a single pc?

In my network I have 25 workstations and some serves. Everything working in local LAN with firewall. The problem is that on one machine (I dont know which one) is installed software which sending data to the internet. Actually I dont know what it is. Last time as I remember was trojan which can create new network interfaces in windows and send some data to the internet. The half speed of my network connection is used by this infected machine. How can I detect which machine it is? How can I listen/capture some traffic and analyze from which machine I have more connections.
Please take a look on this time. Instead of 141-150ms should be 4-5ms.

You may have seen some other posts by me about my final year college project. Im implementing a web based network management website. Iv got a lot of the functionality working at this stage but one part is allocating bandwidth.
Iv got an eircom 3mb broadband connection and I want to be able to split this between users. At the moment I only have my desktop and laptop on the network. Im looking for advice on how i can allocate bandwidth with iptables and/or the tc tool in ubuntu.
My website is on an ubuntu virtual machine and written in php. Whatever about running the iptables and tc commands from php I still need to figure out the actual commands i need to use in the first place.

Since this is my number 1 place for asking questions, I figured I would go here first. So I live in New Zealand where good internet doesn't exist yet, and I'm in a flat with 3 other people and we get 40gb a month which hasn't been lasting more than 2 weeks. It is somewhat of a mystery where all our data has gone, so I need a way to monitor usage. We use a variety of operating systems including linux, xp & windows 7 on my pc, and xbox 360. Is there any kind of integrated solution I can use to monitor everything with password protection so it can't be disabled? I have tried looking in the router, but it doesn't give me many statistics, and I think it combines lan with wan usage. At this stage I don't have the money to make a linux box to put between the router and the switch that can monitor everything, but if it comes to it, I will shell out for one.

I'm having problems with squid, and i don't know how to solve them because I'm new to linux. a. Why squid in my computer often does not work? The process has already started (using the command sudo squid start), but the Internet on client computers can not connect. This can be be resolved if the proxy server computer is restarted. Anybody know why is this happen?
b. How do I set the client bandwidth limitation using squid? I want the client computers can only use maximum 60-70 KB / s. Do I need another additional software package?

I have an ubuntu machine connected to my network which is used as a Minecraft server, storage, and a subsonic server for music. For the most part, the only person using these services, especially during downtime, is just me at home. Which is why I'm surprised that 2-days ago I detected that my network was being slowed to a crawl. There I found that the ip connected to my ubuntu was moving around 170,000 kb on my Netlimiter 3 program.
I have no idea why that is, I closed my ports that were forward for the ubuntu servers, but the bandwidth keeps leaking. Disconnecting the network from the ubuntu computer or turning off the computer stops the odd downloading and uploading. If anybody would have any information of what I can check or shut down in Ubuntu, please let me know. I'm fairly a beginner to the OS, but haven't been able to find a similar problem on this forum.

I'm doing some simulations (using Iperf) to obtain throughputs values of a link between two gigabit ethernet cards for different delays and different drop probability (using netem) .... Now I have to do a 3minute long simulation in which during the firstnute the bandwidth is 1000Mbit/s, 500Mbit/s during the second minute and 1000Mbit/s during ththird one....Does anybody know how can i do this type simulation

I am trying to limit bandwidth of certain ip addresses on my server. I have been doing hours of reading and not getting very far...
So far I believe the iptables command is:
And now I just need the tc command to read those marks and limit bandwidth, I have a gigabit connection and would like to limit each of these ip addresses to 10mbit in and out.
