Networking :: Bandwidth Limit For The Hosts On The Network?
Oct 1, 2010
I Own a netcafe and I want to limit the netspeed for some of the users on the network because some of them maybe use torrent or other ways to eat the bandwidth and the net became so slow for other users.
My task is a way to limit the net speed for some users on the network, I tried a mikrotik RouterOS but it look like a miss to install I wanted an easier way than this, I use linux or windows or any OS to make this task done please help me to do it !!

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.

I want to put a bandwidth limit on the 8000 port. The limit not have to be global! It must be per connection! For example if i put a 20kB/s limit on the 8000 port and I have 3 clients connected to the port, i want that each have the 20kB/s. How can I do that? I readed something about TC, but i don`t know how to use it... I`m a little noobie Sorry for my bad english

I want to limit bandwidth for downloading files with squid. I want to reserve bandwidth for other traffic (esp. web browsing). I know about delay pools but I don't understand well. Some users use download managers to download large movie files. I don't want to block downloading but I want to give them limited bandwidth. May be 5KBps or 6KBps because I have only 512Kbps (64KBps) connection.

recently i rent a xen vps intended to setup a PPTPD vpn server for me and my friends. so we can by-pass the great firewall in china and get back on ....., facebook and stuff. i have already setup the server and i can connect to it without any problem. but i still want to do some further configuration the server:
1. i want to limit the bandwidth to 400k/s per connection.
2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?

I recently read a windows tip which read: - Windows allots 20% of the bandwidth by default for various services like Windows update, spyware checks etc. We can get hold of this bandwith by changing the values of limit reserve bandwidth under QOS packet scheduler. Now my questions: How to limit the bandwidth usage used by ubuntu updates in the above lines?

The limit bandwidth options in U1 don't work for me. I will check the checkboxes and change the values. When I come back later, they are back to being unchecked, with the default values filled back in.

In my household a number of people use the internet. Up to a maximum of 3 wired connections and 2 wireless connections at its peak, all connection through my D-LINK G604T router. The problem is, when one person is downloading or watching ..... or whatever, the others using the internet suffer. I've spent hours configuring QoS on my router, and long story short, no matter how I configure it, it just simply does not work. QoS in no way shape or form limits connection speed (which it says it should). Anyway.
I have a spare computer under my desk, and I'd like to know if I could set this up with a (free) linux distro that limits bandwidth speed per connection. For example, of the 1500 kb/ps (about) my modem pulls, is there a way to limit that to 768 or 512 per connection? so person A can still download, person B can still watch ....., and person C can still play counterstrike with a latency under 100. This would solve many, many arguments in my house I am *fairly* good with computers, but if the distro came with documentation and a GUI that would be awesome.
* TL;DR: *
Is there a linux distro I can load on a spare computer that limits bandwidth per connection, wireless or otherwise, with good documentation?
Failing that is there firmware I can use for my modem (dlink g604t) that would do the same?
Failing that do you know of any good hitmen that would solve my family arguments, ahem, permanently?

Can I, with only the use of IPTABLES, limit the incoming bandwith for a protocol? We have for example servers that have a FTP and HTTP server running and whenever HTTP has a lot of connections open, the other uploads/downloads get a timeout. I know I can limit the number of connections but prefer to limit on protocol level. Is this possible using IPTABLES and if so, can someone indicate how to proceed or provide a link? If it's not possible can someone point me to the right tool for the job?

I have a small office network with windows machines and a Linux Internet access server (CentOS 5.4). For Internet access I use masquerade, so everione can access every Internet service.
I periodicali have quite big traffic from one of the hosts, but I can't figure out which one is that?
Is there any linux command which will show me the bytes/packets (or any useful infos) going to specific hosts?

I have a network connection between 3 computers sharing the same net bandwidth with the same router (modem), I wanted to know how much every one of this network taking from the bandwidth, I want an easy program like switch-sniffer (see the pic) to scan the network and tell me how much every one taking from this network in real time.

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.

The facts are as follows:
1. I have at work a regular LAN with many PCs, each with a DNS-registered public IP. Therefore I am able to address each of these PCs by their fully-qualified names and, for instance, initiate ssh sessions to any of these computers just by typing "ssh <name_of_machine>" from a terminal.
2. Within the aforementioned LAN I have just created a private network with some clients, which access the LAN through a router (a D-link DIR-825). We have created this private network for many reasons, but most importantly because we need to guarantee that the hosts in this network will remain networked among them even if the LAN goes down for any reason (which unfortunately happens often). But we still need to have access to the hosts in the private network from the LAN.
3. I am able to define port forwarding rules in the router in order to access certain services on the private network's clients. For example. I am able to access (by ssh) hosts "H1" and "H2" on the private network from a client on the LAN by defining rules for forwarding ports "P1" and "P2" on the router's public IP to TCP port 22 on the private IPs of "H1" and "H2", respectively. Then I would access each of these hosts from the LAN by using:
>ssh -p P1 [ip.address.of.router] (for accessing H1) and >ssh -p P2 [ip.address.of.router] (for accessing H2)
4. The problem with the port forwarding approach is that it is not easily scalable. For instance, If I wanted to enable ssh access to each host in the private network, I would have to define a port forwarding rule for each machine, and then REMEMBER all these port rules when initiating a ssh session from the LAN in order to point to the right host. And the problem gets worse when considering more services in addition to ssh.
5. The ideal solution would be to be have a means for addressing each host in the private network individually, in much the same way in which I address the hosts in the LAN (which have DNS-registered names). For instance, in order to access hosts H1 and H2 as in the previous example, i would like to be able to just type
>ssh [name_of_host_H1] (for accessing H1) and >ssh [name_of_host_H2] (for accessing H2)
The bottom line:
I guess I can say that what I need is some kind of combined DNS-ing and routing that allows me to communicate with the hosts in the private network from outside of it in a transparent way.
The question is: what are any possible solutions for accomplishing this? I have searched the web and found stuff about things like VPNs, reverse-proxies and NAT servers, but I really can't understand if any of these could serve to solve my problem (BTW, isn't my router doing some sort of NAT-ing already? could I just add some DNS-ing in some way?)

I'm running Ubuntu 10.04 and all was well on my home network until a household member decided to get a laptop and jump on my network. All he does is watch videos on ....., download crap from P2P sites, and maybe even watch p0rn. Is there something I can use to control this or maybe set my router to give him the minimum resources available? Also, I want to block him from downloading junk from P2P sites or places he might get a virus. I'm on a D-Link DGL 4500 Router.

Is it possible to have different /etc/hosts file for different network connections without having to go in and change it every time? The why: I have dyndns and port forwarding to get to my desktop. My laptop is sometimes on the same network, and sometimes not. Also, sometimes the dyndns doesn't update properly, or the outside connection is down, but I want to get to my desktop (and I'm too lazy to walk up the stairs). I'd like to be able to keep one set of bookmarks, ssh command aliases, etc. that would always get to it the fastest and most reliable way possible.

Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.

I have a third party program (tightvnc) which I want to monitor and detect if it loses a connection with a client. I don't care if the client has the program open but isn't doing anything with it, I only want to know if the actual TCP connection is lost.
Since TCP takes forever to die on it's own I was thinking the best way to detect if a connection is lost is by bandwidth the bandwidth on the tcp port allocated to the VNC connection. Are there any tools built in to redhat (RHEL 5.2) which I could use to do this? Since I don't have full control of the operating system I would prefer to use built in tools rather then trying to get a new tool installed.
