General :: Combine Two Internet Connections To Get A Faster Connection?
Oct 25, 2010
I am using Red Hat Linux enterpriser 4 using two physical LAN cards.There are two different ISP internet lines coming into a single gateway computer. Is it possible that if in our one network we are using 2 MB bandwidth and from another network we are getting 2 MB bandwidth.(Two different Networks) and combine it into 4 MB. In bonding it combine the bandwidth or it do loadbalancing ?
The question is can we accumulate or add these two bandwidth in Linux machine and it sent total bandwidth 4 to the end users ?
Lan Card A
IP Address: 192.168.1.250 2MB Bandwidth

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

So I switch between Ubuntu and Windows alot, because some games I can only get to run smoothly in the windows environment. Anyways, one thing I have been noticing ever since I got Ubuntu but never really questioned, was about my download speeds. When downloading a torrent in Windows, I topped out out about 2.0 mb/s. Where as in my Ubuntu install, running the same torrent program (utorrent) and downloading the same file, I was getting 3.0 mb/s. I was wondering, what is it about Ubuntu that is utilizing my internet connection better? Only a hand ful of times have I ever reached 3.0 in my windows install (such as right now while I am downloading a game through steam).

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 have an openvpn bridge up and running (ubuntu to ubuntu, both in vmware fusion machines on macs). My problem is that I cannot get a connection faster than ~9mbps even though 20+mbps is available. I've been troubleshooting for a while and have tried many fixes. I just now did ethtool tap0 and I think maybe I found it. It says the link is 10mbps. I tried to change it with:
sudo ethtool -s tap0 speed 100
but it says ethtool cant change speed on tap0. How can i define the link speed of tap0?

I came to know about namebench tool while working on a setup of DNS server, test results showed some servers working pretty fast. After investigating different options and many tests i managed to keep a good rank of DNS slave server. The idea was to keep checking available fastest DNS servers in the region and modify named.conf accordingly.As many of us are not building a DNS server, I am not going to discuss it in details here, however in case you are using some flavour of GNU/Linux, UNIX you can use following method to have a faster internet experience.
To have it accomplished we are going to use namebench, cron and a small script. namebench looks for the fastest DNS (Domain Name System) servers accessible to your computer.

When I typed netstat -lna, the output:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:580 0.0.0.0:* LISTEN
...
...
Active UNIX domain sockets (servers and established)
Proto RefCnt Flags Type State I-Node
unix 2 [ ACC ] STREAM LISTENING 23581
...
...
Can anyone explain to me:
1. What is "Active Internet connections" & "Active UNIX domain sockets"?
2. What is unix Proto?
3. Difference between LISTEN and LISTENING state.

I would like to have all traffic from the ethernet connection out through the wireless (basically using the box as a router) however I am having some trouble doing this.
I have done this before on Windows however I am having some trouble doing this on linux, I have tried using Squid Proxy however I am having some trouble using configuring/using it.
I am using Yellow Dog Linux however I am willing to change to any other distro as long as it is compatable with PS3 (as this is what im using linux on)

I'm having a bit of Internet trouble with a fresh install of Ubuntu Natty and I haven't been able to track down the problem. I have my desktop running over a wireless network, which connects without fail. Somewhat frequently, however, connections to particular websites will start timing out (google, facebook, stackoverflow, us ubuntu archive, etc.). I'm also having a strange issue where my home page [URL] is redirecting to [URL].
Initially I thought it might be an issue with Comcast DNS, so I updated the router to use OpenDns servers. When that didn't work I started to try accessing some of the problematic sites through my laptop (which is using the same router) and they all connect without problem. The issue seems to be with my Ubuntu install, but I'm not sure where to look.
EDIT After doing some further digging, this is starting to look like a DNS issue. My home page appears the resolve to an incorrect ip address when the redirect issue occurs. Still not sure how to track down the problem, however.

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.

I was having trouble with my wireless connection, it was dropping every 5 minutes or so after upgrading to 10.04 and ran across a thread where someone recommended entering
Code:
sudo apt-get install linux-backports-modules-wireless-lucid-generic
After entering the command I have lost all ability to even use my wireless ability even if it was for 5 minutes. Now I am using a different kernel, internet still drops every 5 minutes, but would love to get my internet up and running again.
I am using a Dell Studio XPS Laptop
Code:

product: MCP79 Ethernet

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.
[URL]
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 3 partitions: 2 linux and 1 windows.
I have been using the 3 OS regularly with no problems. But today suddenly, I had no internet connection with the 2 linux partitions which are complete independent, but no problems with windows. i can keep using the internet under windows with no problems.
I haven't touched any conf files.
I have a usb wifi internet connection.
I just noticed a change in my dmesg file when i start any of my 2 linux partitions.
At the end of the lines I have the following :

I'm having a problem connecting to the Internet on my gNewSense installation. My Internet works fine through Ubuntu and Windows, but not through gNewSense, is there anyway of fixing this? Also, while searching around I found that somebody said I ought to type "dmesg" and copy the results.

I just downloaded openSUSE 11 but I don't have an internet connection. I thought that it will find my cable connection automatically like Ubuntu does, but it didn't. It doesn't have a normal network configuration set-up, there is nowhere that it even gives me a choice to select local internet connection or a cable connection. What do I have to do to set it up.

I am new to Linux. Just installed Ubuntu 10.04 few days back. The problem I am having is not able to connect to internet. Mine is direct cable connection using CAT5 cable terminted to my ethernet card. and I connect to the net using a dial-up connection. I think other end of the cable is terminated to a common switch.I have tried searching it over net. The only thing I could figure out is that I have to do some configuration on pppoe (am i right?)Are there any commands I have to enter or anything like we used to do in windows?

I have a Fedora core 3 box that I am trying to use to replace my current document server. This box was part of a domain at a different location previously. At this location we use a "work group" network. I have set the IP, Gateway, Subnet, and DNS servers. I can see the machine from my XP machine, but cannot get a connection to the internet?

I have just installed Linux Mint 8 Helena & it appears to be working well alongside my xp system. The problem I do have is setting up the much needed broadband connection. I have an adsl speedtouch330 usb modem, with tesco.net as my server, which works just fine on xp hence this mail. Am I missing something obvious, or have I got myself into depths much deeper & complex than I thought.

I want to identify why my ISP is sometimes slow, and wonder how and what tools to use. The problem is as follows: While the lines are very fast, I experience that at times of day where there are presumably high traffic, a new initial connection is very slow and unstable. For example getting response from DNS is slow. And after getting the answer, getting response from a web server is also slow. Or sometimes there is no response at all, and I have to retry. Running a speed test will show high data rates. So it is only initial connection that is slow/unstable.
What is the explanation for these symptoms? Are there some tools and tests I can use to pinpoint the problem from home, without/before contacting the ISP?

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.

When setting up my server I noticed that I could control the amount of connections; the maximum seems to be 256. My server is currently windows 2003 server which is unlimited connections - before I change the server to F10 I need to be able to have unlimited connections (I often go over 256 connections, I have 25 web sites hosted). How do I do this on F10 or is there a better distro for web servers that have thousands of Internet connections at the one time?

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?
