Fedora Networking :: Finding The Upcoming Bandwidth And Specify The Bandwidth Rateto Classes
Nov 18, 2010
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'm trying to shape bandwidth using HTB method and filtering classes with destination mac address. for this I've found two codes but none of them seem to filter bandwidth as i want (test with iperf)
code 1 Code: tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 1000kbit ceil 1000kbit
tc filter add dev eth0 parent 1: protocol ip prio 3 u32 match u16 0x0800 0xFFFF at -2 match u16 0xM4M5 0xFFFF
code....

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.

We have a DSL , how can we calculate the available bandwidth so that we can shape the packet, We can assume the bandwidth to be 100mbps on the ethernet interface However, in DSL devices, the train rate(Bandwidth rate ) is varies according to different situation. How can i get the available bandwidth rate(from varies)?. Any method is there for getting the available bandwidth value....

Calculating the available bandwidth methods IGI/PTR,PATHLOAD,SLOPS,PACKET PAIR...I gone through above methodogies ,when i finish one methods(IGI/PTR) i came to know,one application should run in client side and another application should run in server side (i.e,) Internet Service Provider side,In IGI/PTR method ./ptr-client.c & ./ptr-server.c is there .,if we want available bandwidth,I Should run ./ptr-client.c (in myside)correspondingly ./ptr-server.c then only we wil get a availble bandwidth...My need is without run any application on the server side ./ptr-server.c like that,but I should develop the application only on client side (in my routerside based on linux).. 1:whether it is possible to get the available bandwidth run application in client side only?.if possiblehow i implement the code in client side( only )for getting the available bandwidth ...whether any source code is available?

I'm on Comcast (insert vomit sound here) and they have a 250GB monthly limit. I don't think I'm remotely close to this on a normal month and want to figure out if I could perhaps squeak by with the 5GB limit imposed by Verizon's 3G wireless broadband.
I'm ideally looking for a quick easy-to-use GUI application, rather than something that's done via the command line.
I thought perhaps I could look in my Account and find a nice "You've used X percent of 250 GB thus far" window. Then I called, but Comcast couldn't tell me. They just borked me off to some Windoze application 3rd party which I'm supposed to install.
I run Skype and occasionally download Fedora iso images and so on. Rarely am I doing more than surfing the web, chatting, and sending emails. I doubt I'm even close to 250GBs but I'm guessing that 5GB will end up being problematic.
Are there any programs that will keep track of how much bandwidth I'm using? It'd be great to have an application that runs there in the taskbar and just shows a graph of how much I've used thus far.

how to Divide Equal Bandwidth between / Among Network Clients? e.g if there is total bandwidth = 10Mbps and only 5 clients are online then bandwidth should be divided evenly i.e each client to 2Mbps and if 20 clients are online then 0.5Mbps to each client automatically. [in windows this can be done by bandwidthcontroller software now how it can be done in linux]

i want to ask a question. sometimes i use a gprs modem to connect to the net. the gprs modem uses the usb port. i've connected this pc to another machine through crossover cable. the problem is that when there are two active connections, firefox can't load anything. also how can i share the gprs modem with my other pc that is connected via crossover?
PS. in my active network connections it shows:
eth0- the NIC
and auto eth1 - the gprs modem
i have also tried to change the firefox preferences but to no avail.
Both my computers run on FC11.

I'm using Fedora 9 (64 bit).At the moment, I'm trying to download Fedora 11 using a bit torrent, which is reportedly connected at an average of about 25kbps.The only problem is that whilst the download is active, I can hardly even surf the net properly, even though my current isp connection speed is 5.5mbps.There don't appear to be any background processes running that would utilise any of the bandwidth, and as soon as I pause the torrent the problem disappears.I'm dual booting with Vista, and I don't seem to get the same problem under that OS, so I'm guessing it's something to do with my network settings in Fedora.

I am renting a VPS from[URL].They do not supply a webhosting panel for restarting/shutting down or for seeing monthly bandwidth consumtion. I am running CentOS 5.3. I was wondering if theres any programs that you can install to view monthly/daily bandwidth consumption on our server?

Im looking for a program to monitor the ammount of bandwidth usage per network. Ex: I have lots of networks connected to one server, and i would like to know for example how much is the average bandwitdh usage for network 172.16.2.0/24 and 172.16.5.0/24 for one hour, for example.

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.

I am Network Administrator in a Degree College managing around 2500 Comps. My ISP has terminated its Internet link (15 Mbps) to our Linux Server (Installed 2 NIC) from where Internet connection is extended to rest of the machines in network. I am supposed to send different bandwidth to different departments say 5 Mbps to Hostel, 2 Mbps to Staff room etc. I am new to linux and don't know anything about Bandwidth Management in linux.

I want to use the tc rules for bandwidth control in my lan.i have a linux router(traffic shaper).how i can limit the amount of bandwidth every user has access to per day? For example, any user can't download more than 2 gb per day(or per month).
The information about lan's users(such as a group type,userid,etc.but not any thing about time limiting per user)is in ldap directory on ldap server.the linux server uses ldap server for authentication users when the user login.

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.

I have a proxy/gateway server with X routable addresses and X clients, each connecting to his corresponding address from my server. All clients have public static IP's. I need something like the output of 'pktstat -1 -w 10 -B -i eth0 -n -P -t -T' but that would indicate the biggest'traffic hogs' from my clients.
Something like:
67.78.89.90 <-> my.public.ip.1 1344KB/s up 289KB/s down
56.67.78.89 <-> my.public.ip.2 1203KB/s up 200KB/s down
With this output, I can limit the traffic passing thru my server using a bandwidth limiter on my.public.ip.1 and my.public.ip.2. Pktstat only shows the total traffic from-to the respective IP's gathered in a 10second interval (-w 10). I would like something that would indicate the bandwidth per ip more precisely, I don't want to divide the total traffic by 10 (seconds).
Please note that this will go in a cron job. The interactive tools like iftop are useless (I would like something like a text screenshot of iftop from which I could extract the needed information).

I have a network camera, with a linux OS. We need it to be really precise in its timing for the specific application we want it for. But it's not!
After killing some of the garbage processes on it (and having some achievements, but not enough), it seems that there's some kind of bandwidth limiting applied on the outgoing traffic.
My question: What are all the things that should be done on a machine, running linux, to remove all the bandwidth limitations?
Notes:
1- With my very basic knowledge about traffic shaping in linux, I have made these observations:
# tc qdisc ls dev eth0
qdisc pfifo_fast 0: root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
# tc qdisc del dev eth0 root
RTNETLINK answers: No such file or directory
2- I am trying to download the images from an HTTP link, and I already have about 14Mbps. I want it to reach at least 50Mbps. I can download with speeds higher than this when downloading from another PC on a windows network. So I assume this is not a problem with the cables. Also the eth0 on the camera is said to be a 100Mbps device.

On occasion I see my bandwidth usage using the gnome system monitor going up to 300kbit/s. I just cant figure out what is causing it. I want to know what process or program in using my network like that? I do ssh into different machines and servers, where I would really like to beable to monitor bandwidth usage. It would be very useful to know which utilities people use to see what bandwidth is being used and by which applications / programs / processes / or threads. I don't even know where to start looking. The two small programs I have found are insufficient. bmon and bwm-ng. And tools like wireshark (packet sniffers) are over kill. I would like some thing in the middle, preferably text console based.

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 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.
