Ubuntu Networking :: Manage Multiple Internet Connections With Different Cards?

May 25, 2010

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.

Ubuntu Networking :: Change The Network Card Priority With Multiple Cards?

Sep 26, 2010

I've got two network card interfaces on my computer, one wireless and one wired. The wireless card is connected to the Internet and the wired is connected to the LAN. When only the wireless card is active, Internet works. As soon as i enable the second wired card, Internet stops working. And it seems like Ubuntu chooses the wired card for Internet as soon as it's enabled.

Are there any ways to solve this? So my Ubuntu box always chooses the wireless card for Internet traffic and let me use the wired device for LAN only?

Fedora Networking :: Fc12 Networkmanager And Multiple Wireless Cards?

Nov 9, 2010

I'm having problems getting two wlan cards to work under Networkmanager with F12. I have an old server that I wanted to move, so thought I'd get a USB wlan device for it. before setting up the server, I thought I'd try the USB (an Edimax EW-7711USn - Ralink 2870) on my laptop first. My laptop has an inbuilt ipw2200 card that works fine under NM.

So I've down loaded the DPO_RT3370_LinuxSTA_V2.4.0.1_20100831.tgz file from Ralink, and built the driver (after changing the os/linux/config.mk file for the WPA supplicant settings). I also install the rt2870 firmware (from Ralink) in the /lib/firmware directory. I also blacklisted the rt2800usb driver to ensure that that didn't get loaded.

The problem I have is that I can now get both the ipw2200 device and the rt2870 devices 'working', but they both try to assume the same IP (I want fixed IP's and not DHCP for them) - what is the way to configure the 'devices' so that the rt2870 device is always given IP x and the ipw2200 given IP y?

I think my problem is really my lack of understanding where/how NM handles the files under the GUI config. I used to semi understand how the old network config tool set up it's files and where they were etc. But with NM I'm a bit lost as to how it equates the device with the network settings. Once I have the device working with the correct driver on my laptop, I'll look to apply the same settings on the server (which is then FC13 - but should be simpler as it doesn't have an existing wlan interface).

Ubuntu Networking :: SFTP Multiple Simultaneous Connections

Feb 7, 2010

I really hope someone could help me with this problem. I've been stuck on this for a month.I am using the sftp command to upload files using a bash script.The problem is that it is extremely slow to do it this way. as many of you would know if you have shared server somewhere. I would use scp if remote server supported it, but it doesn't.

Anyway, If any of you have ever used FileZilla, in the Settings, if you go to "Transfers" there is a place where you can set the number of "maximum simultaneous transfers". This feature works wonders with SFTP (and FTP too). It really speeds things up. How do I accomplish this same thing with the sftp command... because I don't want to use a GUI. I don't even mind using FileZilla through the command line if possible... but it does not seem to be possible. I've been stuck on this for a month!!! I've searched everywhere and tried a lot of things with no avail...

Ubuntu Networking :: Multiple Network Connections On Different Networks?

Sep 20, 2010

I am total newby in Ubuntu 10.04. I have just installed it in my office where I have two networks card one connect to a router giving the internet access and the other connected to the windows based work network providing access to the work network sources. In XP everything works fine as I can keep both connections alive and have the results I want.

However although I don't know how to do it in Ubuntu 10.04. Till now I have setup the first connection directly to my router and I have internet access but I cannot set the other one. Another question is how I can force ubuntu to use the router connection as the default one when I log in.

Networking :: Multiple Mobile Broadband Connections

Jun 28, 2010

I have a question concerning mobile broadband connections: Is it possible to have multiple mobile broadband connections active at the same time?I currently have two cellphones connected to my Ubuntu box and both of them can successfully setup an Internet connection for my Ubuntu box (say connection X or connection Y), though not at the same time. Unfortunately both connections are very limited in speed (around 10kb/s each. And this is my only access to the Internet where I live). Therefore, I wish to use the two connections simultaneously to download files from the Internet (file 1 with connection X and file 2 with connection Y). Is this method of doubling my bandwidth possible in Ubuntu?

Ubuntu Networking :: Alix 2d13 - Multiple Network Cards - Unable To Bind More Than One Physical Interface?

Jun 2, 2010

I have a strange problem regarding networking on the Alix 2d13 running Ubuntu 10.04. The Alix has 3 physical network interfaces, lspci says:

00:09.0 Ethernet controller [0200]: VIA Technologies, Inc. VT6105M [Rhine-III] [1106:3053] (rev 96)
Kernel driver in use: via-rhine
Kernel modules: via-rhine

Kernel driver in use: via-rhine

It seems, if more than one cable is connected, a random hardware port is chosen as eth0-eth2. If only one cable is connected the port that is connected is chosen as eth0-eth2. Any idea what's going wrong here?

Fedora Networking :: Multiple ADSL Connections To A Fedora10 Box.

May 18, 2009

I got 2 ADSL accounts from a provider, so I decided to configure a server as a gateway for my other PCs.. I created ppp0 device using pppoe-setup over eth0. Then I configured the second one as ppp1 over eth2 to the second modem.. When I finished, I used ifconfig to check the settings and I got only ppp0 and didn't see ppp1, I tried to ifup ppp1 but I still get one device with ifconfig.. The adsl-start command starts only ppp0.What should I do to get the 2 lines to work simultaneously?Are there any configuration files that need to be edited?

Fedora Networking :: DNS Not Working With Multiple Network Connections

Mar 5, 2010

I have a machine that I'm trying to setup as a reverse web proxy. It will have two NICs, eth0 will face the public network, and eth1 will face the "internal" network (connects to a switch that goes out to the other web servers that are statically assigned a private IP address).

When both interfaces are started, I can ping hosts on the network and the network without problem when doing so by IP, but if I try to run a ping or nslookup command with a DNS name, it does not work. I've tried commenting out my entries in /etc/resolv.conf and adding the DNS entries in the /etc/sysconfig/network-scripts/ifcfg-ethX files directly (DNS1=x.x.x.x and DNS2=x.x.x.x), but the results are the same.

Networking :: Multiple Network Connections - Internal And Wireless

Dec 4, 2008

What I want is quite simple, I have my PC running Linux Mint 5 (Elyssa), and I would like to connect it to both an internal network, which has a file/print server, another machine and will soon host a small cluster. I also have a wireless router connected to the tinterweb.

The thing is using my ethernet I want to connect to the internal network whilst simultaneously using my wireless to deal with the internet, I want to keep the internal network off the net as it really doesn't need to be connected. I can connect to my internal quite happily and also my wireless but not both at once.

Networking :: Routing Torrents With Multiple Connections / Adapters

Jul 8, 2010

Running Fedora 13 and have it working great acting as my firewall/router/samba server etc. The problem is the connection is shared by a fair number of us and the ISP is getting annoyed with the amount of torrent traffic. One of us has access to a wireless network and we'd like to figure out how to route some of the traffic through that without having to disconnect from the current network. I put a wireless card in the fedora box and can connect to the wireless but then it messes up the current network and pretty much nothing works.

At the least if I could run a torrent client (e.g. ktorrent or whatever) on the Linux box and have it download through the wireless card on tcp port XXXXX I would be happy. The torrent client and those tcp/udp ports can be dedicated to that wireless card, the rest of the network doesn't need to get involved if that makes things simpler. Not looking for a step by step tutorial, just an explanation of what needs to be done and a shove in the right direction. My experience is limited to single WAN connections up to this point.

Ubuntu Networking :: Monitor Internet Connections ?

Jun 7, 2010

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?

Networking :: 2 Internet Connections With Shorewall?

Mar 24, 2011

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.

Ubuntu Networking :: Bridging Internet Connections And OpenVPN?

Jul 13, 2011

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:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface * UH 0 0 0 tun0
XXX.XXX.XXX.0 * U 0 0 0 eth0 UG 0 0 0 tun0
default XXX.XXX.XXX.1 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?

Fedora Networking :: Two Internet Connections On F10 Server?

Feb 25, 2009

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.

Networking :: Blacklist IPV6 To Speed Up Internet Connections

Sep 18, 2009

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.

Ubuntu Networking :: Load Balance Or Aggregate(combine) Internet Connections

May 12, 2010

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
