Ubuntu Networking :: Increase Capacity / Bandwidth With More ADSL Line And Modem Combination
May 14, 2010
I am currently running a network with a file server that runs Ubuntu 10.04 Desktop at the moment. DHCP and samba are setup on it for now. Has multiple network cards but we only use the gigabit interface. Here's what I want to do in the near future. I want to provide internet access to the network via ADSL (no better option currently) So what i'll have is one or more ADSL lines and their corresponding modems (most likely D-link ones as they are cheap). As i understand it the server will be doing the job of a router. anyway, point wise here's what i want to be able to do:
1. Have ability to increase capacity/bandwidth with more ADSL line & modem combinations
2. Have user accounts (probably web based setup or any other option) for internet access so that they can be billed per GB.
3. Still be able to share files that are on the local network using local DHCP if possible.
So to an existing network that has files i want to add internet access capability. but users will have to log on so that their usage can be monitored. I have been searching around but maybe the search terms are wrong for what i need accomplished. i don't mind upgrading the ubuntu version to the server edition so long as i can use X11 forwarding atleast so that i can do remote monitoring. VNC is too slow, and using nautilus forwarded via X11 to my desktop sorts out most of my needs. The network provide has suggested maybe using pppoe but i am thinking if there was a welcome page based authentication system then it'd be more easy to monitor?
I want to configure my ADSL but I don't know what should I do. Can you explain me How can I configure it?(I use fc10, ethernet cable <Asus Am608 ADSL modem)
I have an ADSL Internet connection with static IP.I connected through PPPOE from my modem to my ISP.I need to ssh from outside of my home to my home, But i don't know to use which connection between my computer and my modem.(dhcp ,static , bridge or ....)
I want to get an adsl 1 internal pci modem card for my home server. Netcomm's NB100 seems to be the most readily available. Does anyone know if there are ubuntu drivers for it? If not can you suggest a card that does and is easy to get a hold of?
While communicating with cpanel , they said they don't support on any NAT router based network. To host website with cpanel internet should be connected directly with modem (no router) I have a dell poweredge server and recently brought PCI modem. I have 8 IP static addresses from my ISP. cpanel as they said that they don't support networking.
I have 2 pcs at home. I dont have a switch so I can connect only one PC at a time to my adsl router/modem for internet access. In the past I had successfully connected the two PCs (NIC to NIC) to each other using the same ethernet cable which was supplied with my dlink adsl modem.
Recently the motherboard of on of my PC went bad so I replaced it with a new one. The problem is when I connect the two using the same Ethernet cable they won't connect. The lights on the Ethernet port won't light up. I can still connect both of them to the adsl router (NIC to Router) (one at a time).
What are the pros and cons of various current model ADSL modem routers for use with DD-WRT, OpenWRT or Tomato? There are, of course, hardware compatibility lists (HCLs) for each of these (DD-WRT, OpenWRT and Tomato) but many of the models are no longer available and there are so many that researching them all would be onerous. Many pages on the Internet recommend the WRTG54L and that would be great but it is no longer an option except second user which is increasingly difficult. What are the pros and cons of the various chipsets: ADM5120, AR7, IXP4xx and BCM63xx?
My broadband internet connection came with a Nokia-Seimens C2110 Adsl modem. Please help me connect the modem through USB cable as the ethernet card is used to connect my computer(Asus- P5RD2 VM motherboard) to a different computer on LAN. I am in a fix and have no clue how to proceed.
I use an atom based processor of 1.60 ghz on intel d945gclf board. My ram is a zion 1gb @ 533mhz. Hdd is from western digital 80gb @ 7200 rpm. I have a broadband(dsl) connection from bsnl dataone (a state owned telecom service provider). I connect to internet via a huawei wa1003a ethernet/usb/wireless modem which is provided by my service provider. I need a username and a password everytime i connect to internet via dial-up.
I was using windows xp service pack ii. It was nice and easy installing my modem on xp either via usb or ethernet. Both ways it was easy as i have both the drivers with me.Only and main problem was fighting viruses. I tried many free downloadable anti-virus software to protect my maching. Initially they were fine. But after few months they stopped taking regular updates and became non-functional. I also tried symantec corporate v.10. But it has its drawbacks also. It made my machine perform like a snail.I had previously heard about linux based operating systems. But never tried one. As i am an ameteur in using computers windows xp was suiting my needs. Recently i saw an article in the newspaper about ubuntu which is a free open source operating system. And most important to me it is virus free.But here is a problem also. I cannot connect to internet. My ubuntu 9.10 karmic koala is not identifying my modem and a network between my modem and my machine cannot be established. Also i cannot create a dial-up option where i can give username and password.
i cant connect to adsl with pon dsl-provider or any command line. just network manager applet GUI works for me. i follow this guide [URL] and try about 3 hours but without success. i edit /etc/network/interfaces following this thread: [URL] but after any alteration in /etc/network/interfaces and restart network my adsl connections are not work at all and also i lost my GUI applet connections too. then i have to back /etc/network/interfaces to its original content and restart my computer to restore my connections
pon dsl-provider error is:

i have a leased line ( speed 2 MB ) which we use to connect to our mail server , oracle ERP etc.. we have a dhcp scope defined as 192.168.100.1-192.168.101.254. with a default gateway as 192.168.100.90 ( which is a cisco router ) we have a pix firewall ( 192.168.100.10 ).. now the gateway passed all the request to firewall..
we have an ADSL of 4 MB speed.. ip is 83.*.*.230 from ISP. i have a proxy server ( squid ) eth0 is connected to ISP (83.*.*.230).. eth1 to LAN ( 192.168.100.79 ) now the problem is when i put default gateway to eth1 ie 192.168.100.90 the squid connects to internet via leased line.. if i leave the default gateway field empty on eth1 , the squid connects to internet via ADSL ( which i want ) but the problem is no one on the lan cant ping the squid server ( no connectivity to internet for the whole LAN ) how can i solve this problem? i want squid to connect to internet with ADSL, but if i put gateway on eth1 ie LAN squid goes through leased line which i dont want to happen.

I'm trying to establish a connection between two seperate ADSL LANs (coming into the house, but from separate ISPs) to a situation where all hosts on either LAN will be able to reach any host on eiher LAN WITHOUT having to use an excess of plastic routers around the house, and please no Wireless bridges. WiFi will only be available as Access Points.
I've heard that Debian does this kind of static routintg / RIP stuff quite well. And I just happen to have one lined up in the right place, that haven't got at snowballs chance in hell of running WINXP or above. But it kills at textbased datamanipulation/forwarding/rerouting/dropping/scanning ... so I'vew made up my mind. That is what I want to do... Now how do io get around doing stuff like that.
The Debian box is connected to both networks: Hostname: AsusAnd (192.168.1.0/24 - TDC network) and to (192.168.15.0/24 - Profiber network)
Needless to say, but both netmasks are 255.25.255.0 hence the /24 The respective router's LAN addresses are 192.168.1.1 and 192.168.15.1 My Debian are locked to the following IP's (reserved DHCP):
eth0:192.158.1.56 via DHCP from 192.168.1.1 eth1:192.168.15.177 via DHCP from 192.168.15.1
So far so good - Now here we go ! This is not a scenario where i'd like to always want all network-packages to travel the shortest path, nor NESSESARILY use the other ISPs gateway if the first is down or slow, although that'll be super nice.
I suspect that'll involve router-protocols like RIP. I'll be super pleased to get some guidelines there as well, as i suspect it'll be quite easy to implement once everything else is in place. Although RIP isn't our main goal, it probably comes as a close second. I think we all would like as stable and fast a connection as possible.
I was actually so naive that i thought if i added two static routes to the two routers x.x.1.1 and x.x.15.1, that my problems would automatically be solved by my Debian box, and that it would automatically act as a gateway when the routers send their packages for the other net. As long as i was connected to both LANs at the same time.
Note: I haven't changed or tweaked the Debian kernel to do routing. this is a simple stable install from the net-inst.iso of Debian 5. I'd like to keep it that way unless there's no way around it.
my routers have static routes to each other (WITH PROPER CABLING), configured as follows:
(On router with LAN 192.168.1.1) [static route] to 192.168.15.0 with nmask 255.255.255.0 going throuhg gateway 192.158.1.56 ( Taken from above info ) - metric around 2 Similary on my other NIC directly cabled to another switch ---and-then-to-another---> Router
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.
I'm going to set up a new linux router for a company, and have to set up bandwidth throttling. They have an unlimited ADSL internet connection which will be shared between 2 businesses, one being them. I will need to set it up so their connection will never be slowed down by the other business. They will both be connected to the same NIC, but will be on different subnets. How would I go about doing this?
i've just installed opensuse 11.2 everything is working fine but i'm unable to connect to the internet through my adsl modem the network is shown to be active but after i configure the dsl connection i can't see any option from where to connect
Due to PCI limitations on our server, we are trying to connect a Trandnet TDM=C400 ADSL modem via USB but are not having any luck, as the modem appears not to be recognised.
My router/adsl modem is not connected to a power supply so when power goes and comes the network will do a re-boot. Now the problem is my OpenSUSE network won't come back on! I set the static ip as Autoeth0 to eth0 however when network updates I losse eth0. Why is this happening? Why doesn't the PC simply re-connect? Can I do it via command line?
Without Gdm (The GUI Desktop running), or an Internet connection, how does One get pppd or wvdial to connect to a wireless broadband modem?I'm SURE this can be done with any modern Distro without additional downloads...but seem to be missing some crucial step...? I've been trying things like: (scrips for pppd and chat and ln {links} ttyACM0 to /dev/modem?) the modem is definitely on ttyACM0.
I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !
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 would like to increase my "/" filesystem, as you can see, it has 81% occupied, and i would like to decrease the capacity of "/home" and pass it to the /Is this possible?

I have been using an ethernet ADSL Westell modem for years and would like to upgrade to a newish Allied Telesyn USB Modem AT-AR206 in Fedora Core 10. The modem power goes on when plugged into my pc and lsusb shows that it has been recognized with this:
Bus 002 Device 003: ID 1110:9022 Analog Devices Canada, Ltd (Allied Telesyn) ADSL Loader
I used system-config-network but don't have the option of adding this new hardware.
I'm trying to install my first linux system. I would like to use it as a server on an old 386 PC.For the internet connexion (ADSL) i use a Speedtouch USB modem.When i list the peripheral installed on the system, i see the modem with apparently a driver, but the device is listed as non classified. For me it should be directed to DSL0 but..According to some tuto i declared a DSL connection, ppp with ATM (VPI8 and VCI35).I launch the connection with pinternet but the connection failed.
I am doing a school project in which I want to get the bandwidth of a network interface at any given second, or some other small increment of time. I need this for a Perl script I am working on. Therefore it needs to be non-interactive and just prints results.
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.
Just rebuilt my file/print server using an ECS 945GCD-M Atom motherboard. Running it under 9.10 (2.6.31-20) using the same cable and port on my Netgear switch that my old server connected to at 1GB/s without issue (old server's NIC was Intel-based).
Found the driver is an AR813x, & downloaded & installed the latest driver from here (1.0.1.9). sudo lshw -C network now shows that it's using the new driver, but still sitting at 100MB/s:
I have two Linux machines both running Debian (I do not want Windows to be involved at all). One is a desktop and one is a laptop. I desire to connect a not-yet-purchased printer/scanner combination machine only to the internal LAN via my router (Linksys WRT54G) via Ethernet cable, or via wireless if the printer/scanner has that capability. I want to be able to print to that printer (and scan from its scanner) by only having to turn on the printer/scanner and only one of the other computers, and not have to have both Linux machines turned on in order to print and/or scan.
So my questions are: When I look at specific models of printers, what should I be looking for in their specifications that indicates that this configuration is possible (i.e., should I be looking exclusively for printers that say they are "wireless printers" or "network printers")?The reason I ask this question: In my online searching, I thought "networked printer" or "stand-alone network printer" meant just that, but what I found instead are pages and pages of instructions on how to connect the printer locally to a Linux machine, with the associated setup to allow that Linux machine to serve print requests coming from other machines on the LAN. And that approach is not what I want to do (with the notable exception of temporary setup to validate that the printer is responding to requests for printing and scanning from Linux).
Are there particular brands, makes, or models that I would have better luck in getting to work in this manner (i.e., "better stick with HP or Xerox")? Am I kidding myself that a combination printer/scanner would work in the same fashion and still be relatively easy to set up on both Linux machines without resorting to some Windows-centric approach? Result of my searching so far (I have not worked my way through all of these in detail, but plan to): References to local printer connection which is not what I want: Setting_Up_a_Network_Printer_using_CUPS Set up a network printer using cups Set up a printer
The post inside Setting_Up_a_Network_Printer_using_CUPS that starts with "running an HP Photosmart 8450 as a stand-alone networked printer" (where is the permalink?) is as close as I could get, but I am concerned that the instructions given are specific to the HP Photosmart 8450, or specific to the HP vendor, versus for all printers that can be connected to an Ethernet network (not that being locked into HP is going to be a problem necessarily, but I would like to know why if that is the case). Linux compatible printers says "Have a look at LinuxPrinting for known working drivers for printers data base. Also buy from a linux friendly company, ie HP, Brother, Epsom." Later in that thread, someone said Definitely don't buy canon.
