Networking :: How To Allocate Percentages Of Internet Bandwidth For Different Local Connections?
May 18, 2010
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 have a Linux host connected via LAN to Internet. No proxy or squid is used on the host and outgoing traffic to Internet is not limited. I have several local users on this box. Recently bandwidth statistics on the switch/router showed increase in the Internet traffic from this host. How do I monitor the traffic utilization per local user on Linux host? I want to be able to monitor the amount of traffic per port and per user, like user alice downloaded 20GB today via port 22, and so on. Do not offer to use Squid, this is not just web traffic I want to monirot but all amount of incoming/outgoing traffic per user per port.

I want to write a custom rule to allow all connections to the ip addresses on my local network (192.168.2.2 through ...99) but I don't know how. I know adding a custom rule asks me to read a file and put it in "iptables" format, but I don't know how...

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

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

I've got a Ubuntu Server Linux router that I've got 2 internet connections hooked to. One of them is DSL and the other is cable.
What I'd like to do is have everything go through the DSL connection EXCEPT for one desktop, I'd like that system to go through cable for everything.
Here's a diagram of how I've got things set up.

I don't have any more expansion slots on the mainboard of my server for another NIC, also I do a lot of file transferring between a laptop and the desktop I want on the cable connection so I don't want that slowing down the rest of my network.
I've got both providers set up in the providers file and I've got everything going through the DSL connection right now. So far everything I've tried has stopped the desktop from connecting out at all.

I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.

I have a question, regarding the use of two internet connection on the same server. So, the thing is like this: The server will have 3 network adapters: connected to a DSL modem (on this adapter I have one of the internet connections, a PPPoE connection. It's only purpose is to share the internet connection to all LAN users using SNAT.
eth1 ----> the other internet connection, a much more expensive one actually, used for hosting a website, a domain name server, and a qmail server. eth2 ----> LAN connection So what I want is to make eth1 the "default gateway" (for outgoing mail, DNS requests, etc) and, as I said, use the ppp0 connection on eth0 only for internet sharing in LAN.
My question is (since I'l configure this server in about one week), does anybody have any suggestions regarding how could I accomplish this? I mean, I'm affraid that ppp0 will also try to use the default gateway from the other internet connection and vice-versa. Now, I know I can use the ip route/ip rule commands, but for many reasons I'd like to keep it simple and not use them.

I have two internet connections. One is wired ADSL Broadband & another is USB EVDO modem. I can use only one source at a time. That means the traffic will pass through either ADSL or EVDO. Other connection just sits idle. I want to use both the connections together so that I will have increased bandwidth. Is there a way to do that?
My computer has one NIC card. Both ADSL & EVDO use dynamic IPs.

I am a user of Ubuntu 10.04 and I use Firestarter because it lets me know which IPs I am connected to, which ports are used, and which applications are using those ports. The problem is that I can't use Firestarter with my non-sudo account (well, I know that I can change my system settings to do that, but I'd rahther not do it).
So the question is: Is there any application that lets the user monitor the internet connection?

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 set up an openVPN server for a small office. I've gotten the server running, and configured keys, and been able to connect to the server. The trouble is that once I connect with my windows machine to the server, I am unable to bridge through to the www. I have combed through so many settings and tutorials, and I am confused as to how to set up the interfaces configuration file. Here's a sample of my routing table:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0
XXX.XXX.XXX.0 * 255.255.255.128 U 0 0 0 eth0
10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0
default XXX.XXX.XXX.1 0.0.0.0 UG 100 0 0 eth0
How should I be configuring this so that when I'm in the VPN I can get through to the internet?

I have seen several threads lately about slow internet connections here and elsewhere, but I haven't seen anyone post a reply about blacklisting ipv6 so I am curious as to why?Is ipv6 enabled only on certain distro's or is there some other reason that it's not mentioned?
<If anyone wants to try it, to see if it would work for them>
On Slackware 12.2 and Salix 13.0 just add "blacklist ipv6" to the /etc/modprobe.d/blacklist file. I'm not sure about non-slackware based distro's. Unfortunately, I don't know any way of doing it without rebooting.

I'm running ubuntu lucid and i was thinking in purchasing one or more extra wifi cards to try to configure my computer to manage different conections at the same time, with different isp's. The thing is that I'm not quite sure if what i want to do is actually possible.
The easiest way that crossed my mind was to try to configure a / multiple virtual machines that are redirected threw proxies to ubuntu and try to configure that each proxie port goes threw a different internet gateaway. This way i might be able to divide threw different sessions of JDownloader, installed on each virtual machine, the things i want to download. The negative aspect of this idea is having multiple jdownloader sessions will make my laptop work to almost 100% for sure...
Another thought i have was to make JDownloader manage its downloads in only one session redirecting them to my internet conections; the negative thing is that i think i will have to try to modify its source and learn java...
And well my last possible configuration i had in mind was to try to make ubuntu directly add up all my internet conections manage as if it was one. the negative thing here is that i might not be able to get multiple downloads from some sites
Well, all this where just thoughts, im struggling whether to buy another card or not to try to setup any of this configurations but im not really sure if any of them are actually possible. Is there an easy way to manage this?
I just want to take the most out of my internet conections... if i'm at college i have to options that are quite slow, adding them up with two cards would be great, i might also be able to add a third and a fourth conection. Also if i'm on a coffe and i need some bandwith i could try to make it go with an open network arround, etc.

I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.

My problem is that I would like to load balance or aggregate 2 separate Internet connections on my laptop. Currently a hard line ISP is not available so I'm using an Sierra Wireless 885 USB air card. Thing is the card is quite slow. I also can tether an iPhone to the laptop. The ideal solution would be to have both connections being utilized to help speed up the overall experience, even if it is only a modest gain in speed.
as I do not know much about iptables and basic TCP/IP routing, I'm finding it difficult to implement those solutions. If someone can point me in the right direction ( a slightly dumb down how:to? or better explained? )
BTW, both phone and aircard get dynamic IP's. Running Ubuntu 10.4
